The right down payment depends on what you can afford without breaking your budget, not on a single "good" number

There is no universal down payment that works for everyone. A 20% down payment is often called the standard, but it is neither required nor always the best choice for your circumstances. What matters is the amount you can put down without depleting your savings, without taking on high-interest debt to fund it, and without leaving yourself unable to cover closing costs, inspections, and repairs after you buy.

Lenders will work with down payments as low as 3% on conventional loans, though lower percentages come with trade-offs: you will pay mortgage insurance, your interest rate may be higher, and your monthly payment will be larger. A larger down payment reduces what you borrow, lowers your monthly payment, and may may have access to you for better interest rates—but only if the money is already yours and you are not borrowing it or draining your emergency fund to get there.

Key Takeaways

  • Down payments range from 3% to 20% on conventional loans, and the "best" amount is what you can afford without going into debt or emptying your savings.
  • Putting down less than 20% means you will pay private mortgage insurance (PMI) each month until you reach 20% equity, which adds hundreds of dollars annually to your payment.
  • A down payment of 10% to 15% often balances a reasonable monthly payment against keeping cash reserves for emergencies and closing costs.
  • Your credit score, debt-to-income ratio, and the local housing market all affect what down payment amount makes financial sense for you.
  • Saving for a down payment while paying off high-interest debt usually costs you more than buying sooner with a smaller down payment.

How down payment size affects your monthly payment and total cost

The larger your down payment, the less you borrow, and the lower your monthly mortgage payment. On a $300,000 house, a 3% down payment ($9,000) means you borrow $291,000. A 20% down payment ($60,000) means you borrow $240,000. The difference in monthly principal and interest alone is roughly $300 to $350 per month, depending on your interest rate and loan term.

But the real cost difference includes mortgage insurance. If you put down less than 20%, your lender requires you to pay private mortgage insurance (PMI)—a monthly fee that protects the lender if you default. PMI typically runs 0.5% to 1.5% of your loan amount per year, paid monthly. On a $291,000 loan, that is $120 to $360 per month. You pay PMI until you reach 20% equity in the home, which takes years even if you make extra payments. Once you hit 20% equity, you can request that PMI be removed, but you have to ask—it does not stop automatically.

Over the life of a 30-year loan, a smaller down payment costs more in total interest and insurance. But if the alternative is delaying your purchase for years while you save, or borrowing the down payment at a credit card rate, the smaller down payment often wins financially.

Why 20% is not a requirement, even though lenders promote it

The 20% figure became standard because it is the threshold where PMI disappears and lenders see lower risk. It is a marketing number, not a rule. Most borrowers do not put down 20%, and lenders know this. Conventional loans routinely close with 5%, 10%, or 15% down. FHA loans, which are government-backed, allow down payments as low as 3.5%. VA loans (for military members) and USDA loans (for rural properties) often require no down payment at all.

Lenders push 20% because it is better for them: you borrow less, you pay no PMI, and your loan is less risky. But they will lend to you with less if you meet their other requirements—a credit score typically above 620, a debt-to-income ratio below 43%, and proof of income. The trade-off is PMI and a higher interest rate, both of which cost you money each month.

Balancing down payment size against keeping cash reserves

One of the biggest mistakes is putting every dollar into the down payment and closing costs, leaving nothing for emergencies. Homeownership brings unexpected costs: a water heater fails, the roof leaks, the furnace stops working. If you have no savings left after closing, you end up on a credit card or taking out a home equity loan at a worse rate than you could have gotten on your mortgage.

A practical target for many buyers is 10% to 15% down, which keeps your monthly payment reasonable while leaving you with 3 to 6 months of expenses in savings. This assumes you have already paid off high-interest debt (credit cards, personal loans) and have a stable income. If you are self-employed, recently changed jobs, or carry significant debt, a larger down payment—even 20%—may be necessary to get approved, and that is worth the trade-off.

Do not raid your emergency fund or retirement accounts to increase your down payment. The cost of borrowing against a 401(k) or paying early-withdrawal penalties usually exceeds what you save on PMI.

How your credit score and debt affect the down payment you need

Lenders use your credit score and debt-to-income ratio to decide whether to approve you and at what interest rate. A higher down payment can offset a lower credit score or higher existing debt. If your credit score is below 700 or you carry student loans, car payments, and credit card balances, lenders may require 15% or 20% down to approve you, even though they could technically lend with 5%.

Your debt-to-income ratio is your total monthly debt payments divided by your gross monthly income. Most lenders want this below 43%. If you earn $5,000 per month and already pay $1,500 in student loans and car payments, your new mortgage payment can only be about $650 to stay under 43%. A larger down payment lowers your mortgage payment and helps you stay within that limit.

Before you decide on a down payment amount, get pre-approved. A lender will tell you the exact down payment they require based on your credit, income, and debts. This is more useful than any general guideline.

Down payment assistance programs and what they actually cover

Some employers, nonprofits, and state programs offer down payment assistance—grants or forgivable loans that reduce the amount you have to save. These vary widely by location and employer. Some cover up to 5% of the purchase price; others cover closing costs only. A few require you to repay the assistance if you sell within a certain number of years.

If you work for a large employer, check your benefits portal or ask HR whether down payment assistance is available. If you are a first-time buyer, search your state's housing finance agency website for programs specific to your state. The National Council of State Housing Agencies maintains a directory. Be aware that assistance programs often have income limits and may require you to complete a homebuyer education course.

Down payment assistance does not change the math of what you can afford—it just shifts where the money comes from. If a program covers 5% and you put down 5% of your own money, you are still putting down 10% total and still paying PMI if that is below 20%.

When a smaller down payment makes more sense than waiting to save more

If you are renting and paying $1,500 per month, and a mortgage payment (including taxes, insurance, and PMI) would be $1,400, buying now with 5% down costs you less than waiting two years to save 20%. The math changes if you are in a rapidly appreciating market—prices may rise faster than you can save—or if you are paying high rent relative to local home prices. In a market where the rent-to-price ratio is high, renting is cheaper; in a market where it is low, buying sooner often wins.

The other factor is interest rates. If rates are low and you are approved, locking in a rate now and paying PMI for five years may cost less than waiting for rates to drop further (which is not may provide) while you save. PMI is temporary; a high interest rate locks in for 30 years.

Frequently Asked Questions

Is 10% down enough, or should I wait and save 20%?

Ten percent down is enough to get approved on most conventional loans, and you will pay PMI until you reach 20% equity. If you can afford the monthly payment including PMI, and you have emergency savings left over, 10% down is a reasonable choice. Waiting years to save 20% only makes sense if rents are rising faster than you can save, or if your credit score or debt situation will improve significantly in that time.

What happens if I put down less than 3%?

Most conventional lenders require at least 3% down. FHA loans allow 3.5%. Some programs—VA and USDA loans—allow zero down. If you cannot save 3%, you may not may have access to for a conventional loan, but you may may have access to for an FHA loan if you meet income and credit requirements. Talk to a lender about which programs you are may be able to access for.

Can I borrow money for my down payment?

Most lenders will not approve you if they discover you borrowed the down payment on a credit card or personal loan, because it increases your debt-to-income ratio and signals financial strain. Some lenders allow a gift from a family member if you document that it is a gift, not a loan. Check with your lender before accepting borrowed money.

Does a larger down payment may provide a lower interest rate?

A larger down payment improves your approval odds and may may have access to you for a slightly lower rate, but your credit score and the current market rate are the biggest factors in your interest rate. A 20% down payment with a 650 credit score may not get you a better rate than 10% down with a 750 credit score. Get rate quotes from multiple lenders to compare.

What if I put down 15% instead of 20%—how much extra does PMI cost?

PMI on a $255,000 loan (15% down on a $300,000 house) typically runs $120 to $360 per month, depending on your credit score and the lender. You pay it until you reach 20% equity, which takes roughly 5 to 7 years of regular payments. The total cost is $7,200 to $30,000 over that period, but that is often less than the cost of delaying your purchase or borrowing the extra 5% at a higher rate.
