How Much Down Payment Do You Need for a House?

Short answer: Your down payment is the home price multiplied by whatever percentage your loan program accepts, commonly cited figures run from around 3 to 3.5 percent on some low-down programs up to 20 percent on a conventional loan that avoids mortgage insurance. On an illustrative $350,000 home that spans roughly $12,250 to $70,000. Below 20 percent, budget for PMI; at every level, budget separately for closing costs, commonly cited around 2 to 5 percent of the price, which is cash due on top of the down payment itself.

How much down payment do you need for a house? The honest answer is a multiplication, not a memorized number: take the price of the home you are aiming for, multiply by the percentage your loan program and lender will accept, and that product is your target. The percentage is where all the real variation lives, from low-down programs built for first-time buyers up through the 20 percent line that unlocks a loan with no mortgage insurance attached. Most buyers never see this as one equation, because the number gets handed to them in pieces: a loan officer quotes a minimum, a friend mentions 20 percent, a listing shows a price, and nobody puts the three together into a single, personal target.

This walkthrough puts them together. The basic math of price times percentage, why 20 percent became the line everyone references and what PMI actually costs below it, the second number buyers chronically underestimate, closing costs, where the saved cash should live while you build toward the goal, and a monthly plan that turns the target into an automated habit rather than a vague someday. It pairs with our sinking fund walkthrough, because a house down payment is the largest dated savings goal most households ever run, and the calculator turns every figure here into your own numbers.

What the down payment actually buys you

A down payment does three jobs at once, and naming them clarifies why the size matters beyond simply satisfying a lender’s minimum. First, it is your initial equity stake, the slice of the home you own outright on day one rather than financing. Second, it shrinks the loan amount directly, which lowers your monthly principal and interest payment and the total interest you will pay across the life of the loan. Third, above the 20 percent line on a conventional loan, it eliminates PMI entirely, a monthly charge that otherwise persists until your equity crosses a threshold.

None of those three jobs require the same percentage, which is exactly why there is no single correct answer. A buyer prioritizing the lowest possible monthly payment and total interest leans toward the largest down payment they can comfortably afford. A buyer prioritizing getting into a home sooner, perhaps because rent is rising or a family is growing, may reasonably choose a smaller down payment and accept PMI as a temporary cost of timing. Both are rational, and the right choice depends on which job matters most to your situation right now.

The basic math: price times percentage

Strip away the jargon and the calculation is one multiplication: home price times down payment percentage equals your target. On an illustrative $350,000 home, a 20 percent down payment is $70,000, a 10 percent down payment is $35,000, a 5 percent down payment is $17,500, and a 3.5 percent down payment, the figure commonly cited on some low-down first-time buyer programs, is $12,250. The spread between the smallest and largest of those figures is nearly $58,000 on the same house, which is why picking a percentage is the single highest-leverage decision in the entire plan.

The percentage also sets your loan amount, since the loan is simply the price minus the down payment. On the $350,000 example, a 10 percent down payment leaves a $315,000 loan, while a 20 percent down payment leaves a $280,000 loan, a $35,000 difference that reduces both the monthly payment and the total interest paid over decades. Run your own home price and percentage through the calculator to see your version of this spread before picking a tier.

The 20 percent line and why it exists

Twenty percent is not a magic number so much as a threshold most conventional lenders use to decide whether they need extra protection against default. Below that line, the lender’s exposure if you stop paying and the home sells for less than the loan balance is larger, so most conventional loans require PMI to offset that risk. Above the line, your equity cushion is considered large enough that PMI is typically not required at all. The 20 percent figure is a lending convention rather than a law, and some loan types handle the insurance question differently, so confirm how your specific program treats the threshold.

The line matters because it changes two things at once: it removes a monthly cost, and it often improves the interest rate you are offered, since a larger down payment signals lower risk to the lender. For some buyers, reaching 20 percent is a realistic, worthwhile goal to save toward before buying. For others, especially in markets where prices rise faster than a household can save, waiting for 20 percent means renting, and paying someone else’s mortgage, for years longer than accepting PMI on a smaller down payment would require. Neither answer is universally correct, which is exactly why the trade-off deserves its own section below rather than a slogan.

Below 20 percent: what PMI actually costs

PMI is commonly cited as running roughly a half percent to one percent of the loan amount per year, charged monthly until your equity, through paydown, appreciation, or both, crosses the threshold the lender requires. On an illustrative $315,000 loan, the low end of that range is about $1,575 a year, or roughly $131 a month, and the high end is about $3,150 a year, or roughly $263 a month. These figures vary by lender, your credit profile, and the loan type, so treat them as a planning range to budget around rather than a quote you can expect to match exactly.

The important mechanic is that PMI is typically not permanent. As you pay down the loan and, often, as home values rise, your equity share grows, and many lenders remove PMI once the loan balance falls to a commonly cited threshold around 78 to 80 percent of the original or current value, depending on the loan terms. That means a smaller down payment is not a lifetime commitment to an extra monthly bill, it is a bridge cost that usually ends once the equity math catches up, which is the detail that makes the trade-off in the next section worth running rather than dismissing.

The low-down-payment programs, in brief

A range of loan programs exist specifically to make homeownership reachable with less than 20 percent down, and some first-time buyer programs are commonly cited around 3 to 3.5 percent, with others allowing down payment assistance or gifted funds to cover part or all of the requirement. The specific minimums, eligibility rules, and available assistance change by program, by lender, and over time, so this walkthrough deliberately does not assign a single fixed figure to any named program, confirm the current terms directly with a loan officer before building a plan around a specific percentage.

What stays true across programs is the shape of the trade-off: a lower minimum down payment gets you into a home sooner and preserves more of your cash for an emergency fund, moving costs, or furnishing the new place, while it also means a larger loan, likely PMI, and less equity cushion on day one. None of that makes a low-down program the wrong choice, for many buyers it is the only realistic path to ownership within a reasonable timeline, it simply means running the PMI-versus-waiting math honestly rather than assuming more down payment is automatically better.

PMI versus waiting: the trade-off math

The decision between accepting PMI now and waiting to save the full 20 percent comes down to one comparison: the total PMI cost over your expected bridge period versus what you lose by waiting, which includes continued rent, any appreciation you miss on the home you did not buy, and the opportunity cost of your saving rate sitting idle a few more years. On the $315,000 loan example, roughly $200 a month in PMI for three years is about $7,200 total, a real but bounded cost, against perhaps three more years of rent that could easily exceed that figure in many markets, plus whatever home prices do in the meantime.

There is no universal winner here because both sides of the comparison are personal: your local rent, your local price appreciation expectations, which should be treated as uncertain rather than assumed, and how quickly you can actually save the remaining gap all change the answer. A buyer who can close the gap to 20 percent within a year or two, and who is not under time pressure from a lease ending or a growing family, often finds waiting attractive. A buyer facing years of additional saving, or real upward pressure on local prices, often finds that accepting PMI as a temporary bridge cost is the cheaper path overall. Price your own numbers in the calculator rather than defaulting to either extreme.

Closing costs: the second number buyers forget

The down payment gets all the attention, but it is not the only cash due at closing. Closing costs, covering the lender’s origination fee, appraisal, title insurance and search, recording fees, and several smaller charges, are commonly cited at roughly 2 to 5 percent of the home’s purchase price, and they are due separately from the down payment, in cash, at the closing table. On the illustrative $350,000 home, using a 3 percent planning estimate, that is an additional $10,500, a figure many first-time buyers do not budget for until uncomfortably close to closing day.

Closing costs vary by location, lender, and loan type, so the 2 to 5 percent range is a planning estimate rather than a number to expect exactly, and your loan estimate disclosure, provided by the lender during the application process, will show your actual figure well before closing. Some of these costs are occasionally negotiable or partially covered by the seller depending on the market and the terms you negotiate, which is worth raising with your agent, but planning as though you will pay the full estimate yourself is the safer default until a specific credit is confirmed in writing.

Total cash needed: down payment plus closing costs

Add the two numbers together and you get the real cash target, the figure that actually needs to sit in your account before you can close. On the illustrative $350,000 home at 10 percent down, that is $35,000 for the down payment plus $10,500 for closing costs, for a total of $45,500. That combined number, not the down payment alone, is what your savings plan should be built around, because showing up at closing with exactly the down payment and nothing left over is a common and avoidable shortfall.

The combined figure also argues for a small buffer above the calculated total, since the closing cost estimate can shift modestly between your initial estimate and the final numbers, and moving expenses, immediate repairs, or furnishing costs typically follow right behind closing day. Treat the total cash needed line in the calculator as a floor to clear comfortably, not a target to hit exactly with nothing left over.

Where the money should live while you save

A house down payment is a dated, non-negotiable goal, usually one to five years out, and that shape dictates where the money belongs using the same three-word test our emergency fund walkthrough and sinking fund walkthrough apply to every dated goal: safe, liquid, and separate. Safe means no exposure to market swings, because a downturn in the year you plan to buy can force an unwanted choice between selling at a loss or delaying the purchase. Liquid means reachable without penalty or long delay when the closing date arrives. Separate means walled off from everyday spending, so the balance is not quietly eroded by smaller withdrawals along the way.

Within those constraints, a high-yield savings account is the natural home for money you might need within a year or two, while a short-term certificate of deposit timed to land before your target closing date can capture a modestly better rate on money you are confident you will not touch early. What fails the test is the stock market: the temptation to invest a multi-year house fund for better returns ignores that the same correlation our compounding walkthrough warns about for emergency funds applies here too, a downturn can arrive in exactly the year you planned to buy.

Picking a savings timeline

The timeline you choose interacts directly with the monthly number you will need to save, and it is worth setting deliberately rather than letting it default to whatever pace feels comfortable this month. A shorter timeline, a year or two, demands a larger monthly contribution but gets you into a home sooner and reduces the number of years prices can rise out from under your saved percentage. A longer timeline, three to five years, eases the monthly burden considerably but extends your exposure to both rising prices and rising rents paid in the meantime.

There is no universally correct timeline, but two practical anchors help choose one. First, back into it from your gap and a monthly saving rate you can sustain without straining the rest of your budget, covered by our budgeting and 50/30/20 walkthroughs, rather than picking a date first and forcing the math to fit. Second, if your current lease or living situation has a natural end point, let that realistically bound the shortest timeline worth considering, since a plan that requires moving twice is rarely the cheaper path overall.

The monthly number: turning a target into a plan

Once you know your total cash target and your timeline, the monthly saving number falls out of straightforward division: the gap between what you have saved and your target, divided by the number of months until your target date. On the illustrative buyer with a $35,000 down payment target, $8,000 already saved, the gap is $27,000, and at $900 a month that gap closes in 30 months, about two and a half years.

That monthly figure is the one to automate, the same habit our goal-setting walkthrough prescribes for every dated goal: a transfer that happens the day after payday, into the safe, liquid, separate account described above, before the money has a chance to get spent elsewhere. Treat windfalls, a bonus, a tax refund, a gift, as accelerants that shorten the timeline rather than as money that quietly gets absorbed into regular spending, and recompute the monthly number whenever your target price or percentage changes, since both inputs move the target more than most people expect.

A worked sizing: one buyer, start to finish

Run the full machine on an illustrative buyer targeting a $350,000 home with 10 percent down. The down payment target is $35,000, and closing costs at an estimated 3 percent add $10,500, for a total cash need of $45,500. The buyer has $8,000 saved already and can automate $900 a month. The down payment gap alone, $27,000, closes in 30 months at that pace, and folding in the closing cost portion stretches the full plan modestly further unless the buyer saves slightly more or allows a bit more time.

Because the loan amount at 10 percent down is $315,000, the buyer also budgets for PMI: at a planning estimate around 0.75 percent annually, that is roughly $197 a month, added to the mortgage payment once the loan closes rather than during the saving phase. The buyer treats this as a known, bounded bridge cost, expected to end once equity crosses the lender’s threshold through a combination of paydown and, possibly, appreciation. Change any input in the calculator, a different price, a different percentage, a different monthly rate, and the entire plan reprices around your own numbers.

A second worked sizing: a 20 percent down buyer

Run the same machinery on a different shape of buyer, one targeting a smaller $275,000 home but choosing the full 20 percent down payment to avoid PMI entirely. The target is $55,000, and closing costs at the same 3 percent estimate add $8,250, for a total cash need of $63,250. This buyer has already saved $40,000 and automates $1,250 a month, a higher rate made possible by a smaller home price and a longer saving history. The remaining gap, $15,000, closes in 12 months, about a year.

Because this buyer reaches the full 20 percent, the resulting $220,000 loan carries no PMI at all, and the total cash needed, while larger in absolute dollars than the first buyer’s 10 percent scenario, buys a cleaner monthly payment with nothing extra attached. Notice what decided the difference between the two buyers was not virtue, it was starting point and home price: the second buyer simply had more saved already and chose a smaller home, both of which make the 20 percent tier reachable in a shorter window. Your own version of either path prices out in the calculator.

Gift funds and down payment assistance

Many loan programs allow part or all of a down payment to come from a gift, most commonly from a family member, provided the lender receives a gift letter confirming the funds do not need to be repaid, along with documentation showing the money’s origin. Rules on how much can be gifted, from whom, and whether any portion must come from the buyer’s own funds vary meaningfully by loan program and lender, so this is a conversation to have directly with a loan officer rather than an assumption to plan around in advance.

Separately, various down payment assistance programs exist at different levels, aimed at helping qualifying buyers, often first-time buyers or those in specific income bands, cover part of the down payment or closing costs, sometimes as a grant and sometimes as a second loan with its own terms. Because eligibility, amounts, and terms vary widely and change over time, this walkthrough intentionally does not name specific programs or dollar figures, if you suspect you might qualify for assistance, a local housing counselor or your lender is the right first stop to find what currently applies in your area.

Using home sale proceeds: the move-up buyer’s path

Buyers who already own a home and are moving up often fund their next down payment from the equity in their current home, the proceeds from the sale after paying off the existing mortgage and any selling costs, like real estate commissions and typical closing costs on the sale side. This path can produce a much larger down payment than a first-time buyer saving from income alone, sometimes comfortably past the 20 percent line, since years of paydown and any appreciation on the current home both flow into the proceeds.

The planning wrinkle is timing: selling and buying rarely close on the exact same day, so move-up buyers often need a bridge plan, whether that is a contingency written into the purchase offer, a short-term bridge loan, or simply accepting a gap where they carry two housing payments briefly. None of that changes the underlying down payment math, price times percentage still sets the target, it simply changes where the cash comes from and adds a sequencing question worth discussing with your agent and lender well before you list the current home.

Does a bigger down payment always win?

Not automatically, and the question deserves the same honest treatment our debt-versus-investing walkthrough gives to every extra-dollar decision. A larger down payment reduces your loan amount, your monthly payment, your total interest, and, below the threshold, your PMI, all genuinely valuable. But every extra dollar that goes into the down payment is a dollar that cannot also fund an emergency reserve, cover near-term repairs on the new home, or stay invested and compounding if your mortgage rate is relatively low and your investment horizon is long.

The households most often well served by stretching toward a larger down payment are those where reaching it does not drain the emergency fund, delay the purchase meaningfully, or require skipping an employer retirement match in the meantime. The households better served by a smaller, program-eligible down payment and PMI as a bridge cost are often those for whom waiting costs more in rent and foregone appreciation than the insurance ever would. There is no universal answer, only your own numbers, run honestly in the calculator.

How the down payment changes your monthly payment

The mechanical link between down payment size and monthly payment runs through the loan amount: a larger down payment means a smaller loan, and a smaller loan means a smaller monthly principal and interest payment at any given rate and term, exactly the inverse of the extra-payment math our extra mortgage payments walkthrough covers for an existing loan. Below the 20 percent line, the effect compounds, since eliminating PMI removes an entire line item from the monthly bill, not just a fraction of the loan payment.

Over the full life of a loan, this effect becomes large. A smaller loan amount means less interest paid across every remaining year of the mortgage, an effect that is easy to underestimate when staring only at the difference in the upfront cash requirement. If a larger down payment is within reach without compromising your other financial priorities, the monthly and lifetime savings are real and durable, which is exactly why the trade-off in the earlier section deserves honest numbers rather than a reflexive assumption in either direction.

Earnest money versus down payment

These two terms are often confused, and the confusion causes real budgeting mistakes. Earnest money is a smaller deposit, commonly cited in the range of 1 to a few percent of the purchase price, submitted with your offer to show you are serious about the purchase, and it is held in escrow during the transaction. Critically, earnest money is typically applied toward your down payment or closing costs at closing, it is not an additional amount on top of what this walkthrough has calculated, it is usually a portion of the total cash need, paid earlier in the process.

The budgeting mistake to avoid is treating earnest money as separate pocket cash you need on top of your down payment and closing cost total, when in most transactions it simply moves from being held in escrow to being credited at the closing table. Confirm with your agent and lender exactly how your earnest money will be applied, since the specific mechanics can vary by transaction and by local practice.

What happens if you fall short of your timeline

Plans slip, income changes, an unexpected expense interrupts the saving pace, or home prices in your target area rise faster than your fund grows. When that happens, you have several honest levers rather than one forced outcome: extend the timeline and keep saving at the same pace, increase the monthly contribution if your budget allows, target a smaller or different home price that fits your current trajectory, or accept a lower down payment percentage and the accompanying PMI as a temporary bridge rather than delaying the purchase indefinitely.

What falling short should not trigger is raiding your emergency fund or other dated goals to force a closing date that your actual savings do not yet support, a mistake our emergency fund walkthrough specifically warns against, since the fund exists for a different job entirely. Recompute honestly in the calculator, choose one of the real levers above, and treat a shifted timeline as a plan adjustment rather than a failure.

Common down payment mistakes

The recurring failures, gathered for prevention.

• Forgetting closing costs. Budgeting for the down payment alone and discovering a second, separate cash requirement days before closing.
• Sizing on a home price you have not actually confirmed. Saving toward a target that shifts once real listings and local market conditions are factored in.
• Investing a short-horizon fund. Chasing better returns in the market on money needed within a few years, exposed to a downturn at the worst possible time.
• Ignoring the PMI-versus-waiting math entirely. Assuming more down payment is always better, or assuming PMI should always be avoided, without running the actual comparison.
• Treating earnest money as extra cash. Budgeting it on top of the down payment and closing costs rather than understanding it typically applies toward them.
• Draining other goals to force a closing date. Raiding an emergency fund or retirement contributions to hit a timeline the real savings do not yet support.
• Never confirming current program minimums. Planning around a remembered or assumed percentage instead of the figure a current lender actually quotes.

Each mistake adds friction or cost to a plan that the basic multiplication, price times percentage, never required in the first place.

A pre-approval reality check

Before shopping seriously, a mortgage pre-approval from a lender translates your income, debts, credit, and planned down payment into an actual loan amount and estimated rate you qualify for, which is the moment the illustrative math in this walkthrough meets your real numbers. Pre-approval also surfaces the lender’s actual current minimum down payment for the programs you are eligible for, their actual PMI pricing, and a real closing cost estimate, replacing every illustrative figure here with a number specific to you.

Getting pre-approved before setting a final savings target is worth the modest effort, since it can reveal that a program you assumed required 20 percent actually allows less, or that your real closing costs run higher or lower than the 2 to 5 percent planning range used throughout this walkthrough. Treat everything above as the framework for understanding the moving parts, and treat pre-approval as the step that fills in your actual figures.

The bottom line

How much down payment you need for a house is never a fixed number, it is home price multiplied by the percentage your program and comfort level land on, anywhere from a low-down program’s roughly 3 to 3.5 percent up through the 20 percent line that avoids PMI. Add closing costs, commonly cited around 2 to 5 percent of the price, as a separate, equally real cash requirement, keep the savings somewhere safe, liquid, and separate while it builds, and automate the monthly transfer that closes the gap on your chosen timeline. Price your own target in the calculator, confirm the specifics with a lender through pre-approval, and the whole plan turns from a vague someday into a monthly line you can actually track to a closing date.

Everything above is educational and independently written, and none of it is financial or mortgage advice. The percentages, PMI estimates, and closing cost figures are illustrative planning ranges rather than quotes, and every mortgage program, lender, and local market differs. Confirm current minimums, rates, and costs with a licensed loan officer, and take your own purchase decision to a qualified professional before committing to a timeline or a figure.
