Taxable Account vs Retirement Account: Where to Save

Every dollar you save has to land somewhere, and personal finance spends most of its energy explaining the containers rather than the choice between them. There is thorough coverage of what a 401(k) is, what an IRA does, and how a Roth differs from a traditional account. There is far less on the question people actually face on a Tuesday afternoon with 500 dollars they did not spend: does this go into the retirement account or the ordinary brokerage account? The accounts are not competing on quality. They are competing on fit, and fit depends on when you need the money.

This comparison works through that ordering question from both directions. It covers the funding priority most savers are taught and the caveats that priority quietly assumes, what a taxable account really costs in annual tax drag and exit tax, and the things a taxable account buys that no retirement wrapper offers at any price. It then works through the four situations where a plain brokerage account genuinely wins, the asset-location question of which holdings belong in which container, and the withdrawal-order problem that shows up decades later because the accounts interact. Every rate, age, threshold, and dollar figure here is an illustration chosen to show a mechanism, never a statement of current tax law. Confirm today’s rules with the IRS and your own situation with a qualified tax professional, and use the calculator to price your own version.

Why the ordering question is the one that matters

Most savers do not get to choose between a retirement account and a taxable account in the abstract. They have a finite amount of money each month and a set of containers with different rules, and the decision is really an allocation. Ask it that way and the question sharpens: what does each additional dollar buy me in this container versus that one, and what does it cost me in flexibility?

The reason this gets skipped is that the answer sounds obvious. Tax-advantaged accounts have a tax advantage, so use them. That is true and it is also incomplete, because the advantage is paid for with a restriction, and the restriction has a price that varies enormously by person. A 27 year old with a stable job, a full emergency fund, and no plans to stop working before their sixties pays almost nothing for the restriction. A 41 year old who wants out of full-time work at 52 pays a great deal for it.

So the honest framing is a trade rather than a ranking. You are exchanging liquidity for compounding, and the exchange rate depends on your own timeline. Our survey of retirement account types maps the containers themselves; what follows is about the order you fill them in and when the plain one deserves to go first.

What a tax-advantaged wrapper actually buys

Strip away the acronyms and every retirement account does one of two things to the tax timeline. A pre-tax account lets you contribute before income tax is applied, grow with no annual tax, and then pay ordinary income tax on the way out. A Roth account takes money that has already been taxed, grows with no annual tax, and lets qualified withdrawals leave untaxed. Both share the same engine, which is the middle part: nothing is taxed while it compounds.

That middle part is the whole product. In an ordinary account, tax is not a single toll at the end but a recurring leak. Every year a slice of your dividends and realized gains is removed, and every removed slice stops compounding for good. Over one year that is trivial. Over thirty years it is the difference the rest of this comparison is measuring.

The second thing the wrapper buys, in workplace plans only, is access to matching money, which is not a tax feature at all but frequently the single largest reason to use the account. Our explainer on how 401(k) matching works covers the formulas; the comparison of Roth and traditional treatment covers which side of the tax timeline to prefer.

What a taxable brokerage account actually is

A taxable brokerage account, sometimes called an individual or general investment account, is the version with no special rules in either direction. You open it, you fund it with money that has already been taxed, and you buy the same funds you would buy anywhere else. There is no contribution limit, no income eligibility test, no age gate, no required withdrawal, and no paperwork about qualifying events. It is a plain container.

What makes it taxable is that the tax system keeps looking at it every year. Dividends and interest are reported as income in the year they arrive. When a fund inside the account sells holdings, it passes the realized gains through to you. And when you sell, the difference between the sale price and what you paid, your cost basis, is a capital gain that gets taxed.

This is the point where most explanations stop, having established that the taxable account is the worse one. That conclusion is too fast. The taxable account has a genuine set of advantages that no wrapper offers, several of them tax advantages, and the middle sections of this comparison are about those. First, though, the ladder people are usually handed.

The standard priority order most people are taught

The commonly repeated funding order runs roughly like this. Contribute to the workplace plan up to the full employer match. Pay off high-interest debt. Build or top up an emergency fund. Then fill the remaining tax-advantaged space, which typically means a health savings account if you are eligible, an IRA, and the rest of the workplace plan’s allowance. Only then does money go to a taxable brokerage account.

The ladder is built on a single principle: take the highest certain return first. A match is a certain return the moment it lands. Paying off a debt is a certain return equal to its interest rate. Cash reserves are a certain avoidance of borrowing at bad rates later. Tax-advantaged compounding is a strong but uncertain advantage, since it depends on future tax rates. A taxable account is the same investment with the advantage removed, so it goes last.

As a default for a salaried saver with a conventional retirement date, this order is hard to improve on. The sections that follow are not an argument against it. They are an argument for checking which of its assumptions apply to you, because every rung carries one.

Why the employer match sits at the top

The match is at the top because it is the only immediate contractual return available to an ordinary saver. Take an illustrative salary of 60,000 dollars and a plan that adds 50 cents for every dollar you contribute, up to 6 percent of pay. Contributing that 6 percent means putting in 3,600 dollars of your own money and receiving 1,800 dollars from the employer. That is a 50 percent return on the matched portion before the market does anything at all.

Compounded, the match alone becomes a serious number. That 1,800 dollars a year, arriving as roughly 150 dollars a month and growing at an illustrative 7 percent for 30 years, reaches about 183,000 dollars. No allocation decision anywhere else in this comparison moves the result that much, which is why the match outranks every other consideration including high-interest debt in most versions of the ladder.

The caveat is vesting. Matching money commonly becomes fully yours only after a stated period of service, on either a cliff or a graded schedule, and leaving before that point can mean leaving part of it behind. Check your own plan document rather than assuming. The rules that follow the money when you change employers are covered in our walkthrough on what happens to a 401(k) when you leave a job.

Where high-interest debt fits in the order

Paying down a debt is an investment with a guaranteed return equal to its interest rate, and guaranteed is the operative word. A credit card at an illustrative 20 percent is offering a certain 20 percent return on every dollar you send it. No investment account, sheltered or otherwise, can promise that. This is why high-interest debt sits directly under the match on almost every version of the ladder.

The interesting part is where the line falls. At an illustrative 20 percent the answer is obvious. At an illustrative 6 percent, on a fixed-rate loan, against an illustrative 7 percent expected return inside a tax-advantaged account, the comparison is genuinely close and the certainty of the debt payoff has to be weighed against the tax break and the match you might displace. There is no universal cutoff, and anyone who tells you there is has assumed a return they cannot know.

What the ladder does not capture is the psychological weight of debt, which is a real input even though it does not appear in a spreadsheet. Our walkthrough on paying extra on a mortgage works through the same certain-return arithmetic on the largest debt most people carry.

The honest caveats to the standard order

Four assumptions sit underneath the standard ladder, and each one fails for somebody. The first is that you will not need the money before penalty-free withdrawal age. If that is untrue, every dollar you put behind the gate is a dollar you will pay a penalty to retrieve, which can wipe out years of tax advantage in a single withdrawal.

The second is that your workplace plan is reasonably priced. Plans vary widely in what they charge, and past the match, an expensive plan is competing on tax treatment alone against a cheap brokerage account. There is a crossover point, and it is closer than most people expect.

The third is that your tax rate today is at least as high as it will be when you withdraw. Pre-tax contributions are worth the most to people in higher brackets now, and worth least to someone whose income is unusually low this year. The fourth is that you have somewhere to put the money at all: contribution limits are annual, set by the IRS, and revised regularly, and once a year’s room is unused it does not come back.

Tax drag: what a taxable account actually costs

The cost of a taxable account during accumulation has a simple shape. Each year, the account distributes some income, that income is taxed, and the tax money leaves. The size of the leak is roughly the distribution yield multiplied by the tax rate applied to it.

Two illustrative examples show how much the holding matters. A broad stock index fund distributing an illustrative 1.5 percent in qualified dividends, taxed at an illustrative 15 percent, leaks about 0.22 percentage points a year. A bond fund distributing an illustrative 4 percent in interest, taxed at an illustrative 22 percent ordinary rate, leaks about 0.88 percentage points a year, roughly four times as much. Same account, same tax code, very different drag.

The worked example throughout this comparison uses an illustrative drag of half a percentage point, which sits between those two and reflects a mixed portfolio with some turnover. That means a 7 percent gross return compounds at 6.5 percent net inside the taxable account and at the full 7 percent inside a wrapper. Half a point sounds like nothing. Watch what it does across three decades.

One dollar of gross pay, three wrappers

Here is the comparison done fairly, which most versions are not. The fair way is to start from the same amount of gross pay, because a pre-tax contribution and a taxable deposit do not cost the same take-home. Assume 500 dollars a month of gross pay directed at savings for 30 years, an illustrative 7 percent return, an illustrative flat 22 percent income tax rate, and an illustrative 15 percent long-term capital gains rate.

Route one, pre-tax: the full 500 dollars goes in, grows to about 610,000 dollars, and is taxed as ordinary income on the way out. At 22 percent that leaves about 475,800 dollars of spendable money. Route two, Roth: the 500 dollars of gross pay becomes 390 dollars after tax, which grows to about 475,800 dollars, all of it spendable. At an identical rate now and later, the two wrappers land on exactly the same number, which is the classic result.

Route three, taxable: the same 390 dollars a month goes in, compounds at 6.5 percent after drag to about 431,400 dollars, of which 140,400 dollars is your basis and 291,000 dollars is gain. Selling the whole balance at an illustrative 15 percent leaves about 387,750 dollars.

The gap between the sheltered routes and the taxable route is about 88,000 dollars on these assumptions, about 18.5 percent of the sheltered result. That is the honest size of the tax advantage over 30 years for this saver. It is large. It is also not infinite, and the next section shows where it comes from, which turns out to matter for how you respond to it.

Where the gap actually comes from

Split the 88,000 dollar gap into its two charges. The annual drag cost 44,400 dollars, being the difference between the 475,800 dollars the Roth reached and the 431,400 dollars the taxable balance reached. The capital gains tax on the sale cost 43,650 dollars. The two are almost the same size, which surprises most people, because the exit tax is the one everybody thinks about and the drag is the one nobody sees.

That split has a practical consequence. Roughly half the cost of a taxable account is charged before you sell anything, which means you cannot avoid it by holding forever. But the other half you have real control over: you choose when to sell, whether to sell at all, and what rate applies when you do. Nobody controls the timing of a required distribution from a pre-tax account in the same way.

Look at the small dark segment. A full liquidation of a 30 year taxable account cost about a tenth of the balance, because only the gain is taxable and only at long-term rates. The same balance inside a pre-tax account would have been taxable in full as ordinary income. This is the fact that makes the taxable account far less punitive than its reputation suggests.

What the taxable account buys that the wrapper cannot

Set the tax arithmetic aside and list what the plain account gives you that no retirement wrapper does. You can withdraw any amount at any age for any reason. You are never told to take money out. Your long-term gains are taxed under a separate and generally gentler set of bands than ordinary income. You can deliberately realize losses and use them. Your heirs may receive a reset cost basis. And you can hold the money for a goal that has nothing to do with retirement.

None of these are consolation prizes. Several are genuine tax features, not merely liquidity features, and one of them, the basis reset, is a tax advantage a retirement account cannot match at any contribution level. The reason they get overlooked is that they are hard to compare against a single compounding number, so they do not appear in the chart above.

The rest of this section takes them one at a time, because a decision made only on the 88,000 dollar figure is a decision made on half the information.

Access at any age, and what the penalty gate costs

The retirement wrapper’s restriction has a price, and you can put a number on it. Withdrawing from a pre-tax account before the commonly cited penalty-free age generally means ordinary income tax plus an additional penalty. On an illustrative 10,000 dollar withdrawal at an illustrative 22 percent tax rate and an illustrative 10 percent penalty, you would hand over about 3,200 dollars and keep about 6,800.

That 32 percent haircut is what the flexibility of a taxable account is worth in a bad year, and it is worth comparing against the 18.5 percent advantage the wrapper produced over 30 years in the chart. One forced early withdrawal can undo a great deal of patient tax sheltering. This is the strongest argument for not routing your entire savings capacity behind the gate.

There are recognized exceptions to the penalty, including certain separations from service, a series of substantially equal periodic payments, disability, and specific expense categories, and the list is maintained by the IRS and revised over time. Direct Roth IRA contributions are the notable soft exit since the tax on them was already paid; the ordering rules are in our walkthrough on Roth IRA withdrawal rules, and the pre-tax side is covered in our walkthrough on 401(k) withdrawal rules.

No required distributions on money you already own

A pre-tax retirement account carries a deferred tax bill, and the tax system does not defer it forever. At an age set by legislation, holders of pre-tax accounts are generally required to withdraw a minimum amount each year, calculated by dividing the balance by a factor that shrinks as you get older. Those withdrawals are ordinary income whether or not you need the money.

The mechanism is worth feeling rather than just knowing. Take the illustrative 610,000 dollar pre-tax balance from the worked example and an illustrative divisor of 25. That forces about 24,400 dollars of taxable income in a single year, which stacks on top of pension income, benefits, and anything else, and can push you into a higher band or across an income-tested threshold you had not thought about. The real divisors and ages come from IRS tables and have changed more than once; our explainer on required minimum distributions covers the mechanism in full.

A taxable account has no such rule, ever. It is money you already own outright, on which tax has already been settled except for the unrealized gain. Nobody makes you touch it, which is a genuine planning asset in the years when your income is already high.

Long-term capital gains are not ordinary income

This is the most underrated point in the whole comparison. Money leaving a pre-tax retirement account is ordinary income, taxed under the same bands as wages. Money leaving a taxable account after a long enough holding period is a long-term capital gain, taxed under a separate schedule of bands that is generally gentler, and only the gain is taxed, not the whole withdrawal.

Both statements together produce a result that looks wrong at first. In the chart above, liquidating the entire taxable account cost about a tenth of the balance. Withdrawing the entire pre-tax balance at an illustrative 22 percent cost 22 percent of the balance. The wrapper still won overall, because it started with more money in it and never leaked along the way, but the exit was the taxable account’s better half of the trade, not its worse one.

The holding period matters, since gains realized within a short window are generally taxed as ordinary income instead, and the bands, rates, and holding thresholds are all set by law and revised. Treat the mechanism as durable and the numbers as needing a check with the IRS each year.

Tax-loss harvesting, the one-way advantage

A retirement account has no concept of a loss. If an investment inside a 401(k) falls, nothing happens on your tax return, because nothing inside the wrapper is on your tax return. A taxable account is different: a realized loss is a usable thing.

The mechanism is that realized capital losses first offset realized capital gains, and net losses beyond that can be deducted against ordinary income up to a limit set by law, with anything above that limit carried forward to future years indefinitely. At an illustrative 22 percent rate, deducting an illustrative 3,000 dollars of net losses against ordinary income is worth about 660 dollars in that year. It is not transformative, but it is a benefit the wrapper structurally cannot offer.

Two honest limits. The wash-sale rule disallows the loss if you buy back a substantially identical holding within a defined window around the sale, and it can reach across accounts you control, so it is easy to trip accidentally. And harvesting a loss lowers your basis, which means part of the benefit is deferral rather than elimination. The annual deduction limit and the wash-sale window are set by the IRS, so confirm both before relying on either.

The basis step-up at death

Of all the taxable account’s features, this is the one with the largest potential value and the one most exposed to legislative change. Under the treatment commonly described today, assets held in a taxable account can have their cost basis reset to the value at the date of death when they pass to heirs, which can erase the embedded capital gain entirely for the person inheriting.

Apply it to the worked example. The taxable account held 291,000 dollars of unrealized gain. An heir receiving a stepped-up basis and selling promptly could face little or no tax on that embedded gain. The 610,000 dollar pre-tax account has the opposite property: every dollar of it is untaxed income to the heir, generally on a compressed withdrawal timetable, so the deferred tax bill is inherited along with the money.

Two cautions apply with force here. Estate rules, basis treatment, and inherited-account timetables have all been changed by legislation before and can be again, so nothing above should be treated as a settled plan. And estate planning is genuinely specialist territory where a qualified professional is worth the fee.

When taxable wins: retiring before penalty-free age

This is the clearest case. If you intend to stop working meaningfully before the commonly cited penalty-free withdrawal age, the years between your last paycheck and that age have to be funded by something, and a pre-tax retirement account is an expensive way to fund them.

A taxable account is the natural bridge. It has no age gate, its gains are taxed under the gentler long-term schedule, and in early retirement your ordinary income is often unusually low, which can make realizing gains cheaper than it would ever be during your working years. Someone who spent their entire savings capacity filling retirement wrappers has technically optimized the tax math and practically built a bridge with no first span.

There are alternative bridges. Substantially equal periodic payments, staged conversions timed years ahead, and Roth contribution basis can each supply part of the answer, and our walkthrough on doing a Roth conversion covers the timing that a conversion ladder depends on. A taxable account remains the simplest bridge, because it requires no rule to be satisfied at all.

When taxable wins: a goal five to fifteen years out

The wrapper’s advantage is a compounding advantage, which means it grows with time and is small when time is short. Its restriction, by contrast, is fully in force from the first day. That asymmetry is why medium-horizon money often belongs in a taxable account even when sheltered space is available.

Consider a house deposit eight years out, a sabbatical at eleven years, or a business you intend to start in six. Over that span the tax drag on a reasonably tax-efficient portfolio costs a modest amount, while the penalty for pulling the money out of a retirement account at the moment you need it costs a great deal. The illustrative 32 percent haircut from the access section arrives in year eight, and no plausible amount of tax sheltering over eight years covers it.

There is a separate question about whether money needed in five to fifteen years should be invested at all or held closer to cash, which depends on how fixed the date is and how much of a shortfall you could absorb. Our walkthrough on setting financial goals works through matching a horizon to a container, and our explainer on high-yield savings accounts covers the cash end of that spectrum.

When taxable wins: you have already filled the space

This is the simplest case and the one that needs the least argument. Tax-advantaged room is capped annually, the caps are set by the IRS and adjusted over time, and once you have used the workplace plan allowance, the IRA allowance, and a health savings account if you are eligible, there is nowhere else sheltered to put the money.

At that point the taxable account is not a compromise, it is the next container. The relevant question stops being whether to use it and becomes how to use it well, which is mostly a matter of holding tax-efficient investments in it, keeping turnover low, and being deliberate about when gains are realized. Those are the asset-location and withdrawal-order questions below.

High earners who hit the limits early also face a second question, which is whether income-based eligibility rules block the direct route into some accounts. That is a separate mechanism with its own workaround, and it is covered in our walkthrough on the backdoor Roth IRA. Our comparison of IRAs and 401(k) plans covers the sequencing between the two main wrappers before the taxable account comes into play.

When taxable wins: an expensive plan menu

Here is the case people miss, and it deserves arithmetic rather than assertion. Suppose your workplace plan, past the match, effectively costs a full percentage point more per year than what you could buy in a brokerage account, so the wrapper compounds at 6 percent while the taxable account compounds at 6.5 percent after its half point of drag.

Run the same 500 dollars a month of gross pay for 30 years. The pre-tax route now reaches about 502,300 dollars and, taxed at an illustrative 22 percent, leaves about 391,800 dollars spendable. The taxable route still lands at about 387,750 dollars. A gap of roughly 88,000 dollars has collapsed to about 4,000 dollars, which is inside the margin of error on every assumption feeding it.

The conclusion is not that expensive plans should be avoided past the match, because a real plan’s costs are rarely that stark and the match itself is untouchable. The conclusion is that fees and tax treatment are the same kind of quantity, both measured in percentage points a year, and they can be compared directly. Look up what your plan actually charges before assuming the wrapper wins by default.

Asset location: which holdings belong where

Once you hold both account types, a further optimization appears: given that different investments are taxed differently, which ones should sit in which container? The principle is to put the holdings that generate the most annual taxable income where that income cannot be taxed.

That points in a few consistent directions. Bond funds, high-turnover funds, and real estate trusts tend to distribute income taxed at ordinary rates, so they generally do more damage in a taxable account and fit better inside a tax-deferred wrapper. Broad stock index funds and exchange-traded funds distribute relatively little and defer most of their return into unrealized appreciation, so they sit in a taxable account comparatively well. Assets with the highest expected growth have the strongest case for a Roth account, since the wrapper never taxes what they become.

Three honest caveats. Asset location is second-order: your savings rate and your overall allocation move the outcome far more, and a portfolio that is correctly located but wrongly allocated is not winning. It complicates rebalancing, because you can no longer treat every account as interchangeable. And the drag figures that drive it depend on current tax treatment of dividends, interest, and distributions, all of which change.

Withdrawal order in retirement

Decades later, the same accounts pose a mirror-image question. The conventional answer is to spend taxable money first, then tax-deferred, then Roth last, on the reasoning that the sheltered accounts should keep compounding as long as possible and the Roth is the most valuable shelter of all.

It is a sensible default and it is beaten often enough to be worth questioning. Many people have a window of unusually low income between their last paycheck and the start of required distributions and claimed benefits. Spending only taxable money in that window wastes low tax bands that will never come back, and it leaves the pre-tax balance to grow into a forced withdrawal at a higher rate later. Deliberately drawing some pre-tax money in that window, or converting some of it, can cost less across the whole retirement than the conventional order does.

That is a multi-year optimization involving your own income, your state, benefit timing, and income-tested thresholds, which is why it is one of the few places where paying for advice reliably pays for itself. Our walkthrough on doing a Roth conversion covers the mechanism, and our explainer on required minimum distributions covers the forced-income side of it.

Common mistakes in the ordering decision

The first is treating the ladder as a rule rather than a default, and locking away money that a foreseeable life event will demand back at a penalty. The ladder assumes stability it cannot verify on your behalf.

The second is the opposite error: keeping everything liquid because retirement feels distant, and permanently forfeiting annual tax-advantaged room that does not carry forward. Unused space is the quietest expensive mistake in personal finance, because nothing ever shows up as a loss.

The third is comparing accounts on different amounts of money, which is what happens whenever someone compares a pre-tax contribution to a taxable deposit of the same size without accounting for the tax the taxable deposit already paid. The fourth is buying a tax-inefficient holding in a taxable account when the identical exposure could have sat inside a wrapper. The fifth is ignoring fees entirely, which the expensive-plan section above prices. And the sixth is emptying an emergency fund into a retirement account, which converts a three month cash cushion into a penalty-gated balance; our walkthrough on building an emergency fund covers what that cushion is for.

Pricing your own version

Every number in this comparison is an illustration, and the useful move is to replace them with yours. The variables that matter are your monthly amount, your horizon, the return you assume, the income tax rate you expect now and later, the capital gains rate you expect, and how much annual drag your actual holdings produce. Change any one of them and the gap between the containers moves.

Three things are worth testing deliberately. First, the horizon: shorten it from 30 years to 10 and watch the wrapper’s advantage shrink, which is the mathematical version of the medium-horizon argument. Second, the future tax rate: assume a lower rate at withdrawal than at contribution and the pre-tax route improves sharply, which is the whole pre-tax case in one input. Third, the drag: run it at a quarter point and at a full point and see how much of the answer was riding on an assumption about which funds you hold.

If the conclusion flips inside a range of assumptions you consider plausible, that is genuinely useful information. It means the decision is close, and a close decision is one where flexibility deserves more weight than a marginal tax edge. The calculator runs the underlying compound growth engine, and our explainer on compound interest shows the engine on its own. Our walkthrough on how much to save each month covers the input that matters more than any of this.

When to bring in a professional

Some versions of this decision are straightforward enough to reason through alone. A salaried saver with a conventional retirement date, a decent plan, an emergency fund in place, and no plans to stop working early can follow the standard ladder, put the overflow in a brokerage account, and be close enough to optimal that the remaining difference is not worth agonizing over.

Others are not. If you are planning to stop working well before penalty-free age, if you hold concentrated stock or equity compensation, if you are within a few years of claiming benefits or enrolling in Medicare, if you are weighing a move between states, if estate planning and the basis question are in play, or if the amounts are large enough that being wrong matters in absolute terms, the interactions get complicated quickly and a mistake can be permanent.

The relevant professional is often a tax professional rather than an investment one, because most of what is being decided here is tax timing. Our explainer on fiduciary financial advisors covers what to look for in someone whose recommendations are not conflicted.

The bottom line

Taxable account versus retirement account is not a quality contest. It is a trade of liquidity for compounding, and the exchange rate depends entirely on when you need the money. The standard order, match first, then high-interest debt, then a cash cushion, then the rest of the tax-advantaged space, then taxable, is a strong default for a conventional working life, and in this comparison’s illustration the wrapper was worth about 88,000 dollars over 30 years on 500 dollars a month of gross pay, about 18.5 percent of the sheltered result. That advantage was split almost evenly between annual drag and exit tax, and a single percentage point of extra plan fees very nearly erased it. What the taxable account gives back is access at any age, no forced distributions, gentler long-term gain treatment, harvestable losses, a possible basis reset for heirs, and a home for goals that are not retirement, which is why it deserves a place in most plans rather than only the leftovers. Every rate, age, threshold, and dollar figure above is a teaching illustration rather than current law, and contribution limits, capital gains bands, penalty ages, and estate basis rules all change, so confirm today’s figures with the IRS and take your own situation to a qualified tax professional. Run your own numbers through the calculator before you decide which container gets the next dollar.

SumLoft writes about how financial arithmetic behaves, and nothing in this comparison is tax advice, investment advice, or a recommendation to fund or avoid any account. The returns, tax rates, drag assumptions, penalty percentages, divisors, and dollar amounts used here were chosen to make a mechanism legible, not to describe the rules in force on any particular day: contribution limits, capital gains bands, penalty-free ages and their exception lists, required distribution factors, wash-sale definitions, and the treatment of inherited assets are all set by the IRS and by legislation, and all of them have moved. Your own answer also turns on facts this article cannot see, including your state, your plan documents, your future income, and your timeline.
