What a down payment is and why lenders ask for one
A down payment is money you give upfront when you borrow for a large purchase — usually a home or car. The lender then finances the rest. If you buy a $300,000 house and put down $60,000, the lender gives you a $240,000 mortgage. The down payment is yours to lose if you stop paying; it's the lender's cushion against that risk.
Lenders require down payments because they reduce the lender's exposure. If you default and the house sells at auction for less than the loan amount, the lender's loss is smaller when you've already paid part of the price yourself. A larger down payment also signals to the lender that you have savings and are serious about repaying.
Down payment size varies by loan type. Mortgages typically ask for 3 to 20 percent of the home price. Auto loans often require 10 to 20 percent. Personal loans may ask for nothing, or they may require collateral instead. The amount you can afford to put down directly affects the monthly payment you'll owe and the total interest you'll pay over the life of the loan.
Key Takeaways
- A down payment reduces what you borrow, which lowers your monthly payment and the total interest you pay over time.
- Putting down less than 20 percent on a mortgage usually triggers private mortgage insurance, which adds to your monthly cost until you reach 20 percent equity.
- Down payment money comes from your own savings and is not borrowed; it's the only part of the purchase price you own outright from day one.
- The down payment amount you choose affects both the interest rate the lender offers and whether you'll need to pay insurance or meet other conditions.
- Some programs and loan types allow down payments as low as 3 percent, while others require 10 to 25 percent depending on your credit and the lender's rules.
How down payment size changes your monthly payment
The larger your down payment, the smaller the loan amount, and the smaller your monthly payment. On a $300,000 house at 7 percent interest over 30 years, a $60,000 down payment (20 percent) means you borrow $240,000 and pay roughly $1,596 per month. A $30,000 down payment (10 percent) means you borrow $270,000 and pay roughly $1,797 per month — about $200 more each month for the same house.
That difference compounds over 30 years. The extra $200 per month adds up to $72,000 in additional payments. You also pay interest on the larger loan amount, so the total interest you owe rises even faster than the payment difference suggests. A smaller down payment is cheaper upfront but more expensive over time.
Down payment size also affects the interest rate itself. Borrowers who put down 20 percent or more often receive lower rates than those who put down 10 percent, because the lender's risk is lower. A rate difference of even 0.5 percent compounds significantly over 30 years, adding tens of thousands of dollars to what you ultimately pay.
Private mortgage insurance and the 20 percent threshold
Private mortgage insurance (PMI) is a monthly fee you pay when you borrow more than 80 percent of a home's value — in other words, when your down payment is less than 20 percent. PMI protects the lender, not you. It covers the lender's loss if you default and the home sells for less than what you owe.
PMI typically costs 0.5 to 1.5 percent of the loan amount per year, paid monthly. On a $270,000 loan, that's $112 to $337 per month. You pay PMI until you reach 20 percent equity in the home — either by paying down the principal or by the home appreciating in value. Once you hit that threshold, you can request that PMI be removed, though you must ask; lenders do not remove it automatically.
PMI is a real cost that makes smaller down payments more expensive than the payment calculation alone suggests. A 10 percent down payment might look affordable at first, but PMI adds hundreds of dollars per month until you've paid enough principal to reach 20 percent equity — which can take 5 to 10 years depending on your payment schedule and home appreciation.
Down payment sources and what lenders will and won't accept
Lenders want to know where your down payment money came from. They ask because they want to confirm you actually have savings and are not borrowing the down payment from someone else (which would increase your total debt). Most lenders accept down payment money from your own bank account, savings account, or money market account.
Many lenders also accept down payment gifts from family members, though they usually require a signed letter from the gift-giver stating the money is a gift and not a loan you must repay. Some programs allow down payment information from nonprofits or government programs, but the rules vary by program and lender. A few lenders will not accept gifts at all, or will only accept them from when ready family.
Lenders typically do not accept down payment money that is itself borrowed — for example, a personal loan, a credit card cash advance, or a loan from a friend. They also scrutinize large deposits that appear shortly before you explore, because they want to confirm the money has been in your account long enough to be genuinely yours. Ask your lender what documentation they need before you move money around.
Down payments on cars versus homes
Auto loans and mortgages handle down payments differently. For a car, the down payment is usually 10 to 20 percent of the purchase price, and the dealer or lender deducts it from the price before calculating the loan. A $30,000 car with a $6,000 down payment means you finance $24,000. The down payment reduces the loan amount when ready and proportionally.
For a home, the down payment works the same way mathematically, but the consequences are larger and longer-lasting. A mortgage lasts 15 to 30 years, so a smaller down payment affects your finances for decades. An auto loan lasts 3 to 7 years, so the impact is shorter. Additionally, a home can appreciate or depreciate, which affects when you reach 20 percent equity and can remove PMI. A car depreciates predictably, so you're underwater (owing more than the car is worth) for the first few years regardless of down payment size.
Auto lenders are also more flexible about down payment size. Some offer loans with no down payment required, especially to borrowers with good credit. Mortgage lenders almost always require at least 3 percent down, and many require 5 to 10 percent. The stakes are higher with a home, so lenders are more cautious.
Strategies for saving for a down payment
If you're saving for a down payment, the amount you need depends on the purchase price and the lender's minimum requirement. For a $300,000 home with a 10 percent minimum, you need $30,000. For a $25,000 car with a 10 percent minimum, you need $2,500. Calculate the target amount first, then work backward to figure out how much to save per month.
Keep down payment savings in a separate, high-yield savings account so the money is straightforward to find and earns interest while you wait. Do not invest down payment money in stocks or other volatile assets if you plan to buy within the next few years; you need the money to be there when you're ready, not subject to market swings. A high-yield savings account currently pays 4 to 5 percent annually, which is better than a regular checking account and keeps your money safe.
If you're buying a home, look into down payment information programs in your state or county. Some programs offer grants or low-interest loans specifically for down payments, and some allow you to put down as little as 3 percent if you meet income requirements. Your mortgage lender or a local housing counselor can tell you which programs you might explore. These programs exist because down payment size is often the biggest barrier to homeownership, and reducing that barrier helps more people buy.
What happens if you can't save a full down payment
If you cannot save the down payment amount a lender requires, you have a few options. You can wait and keep saving, which delays the purchase but gives you more time to build equity from day one. You can look for a lender with a lower minimum — some mortgages accept 3 percent down instead of 5 or 10 percent, though you'll pay PMI longer and at a higher rate. You can explore down payment information programs, which may cover part or all of the gap.
You can also ask family members for a gift, as long as you're prepared to provide the gift letter lenders require. Some employers offer down payment information as an employee benefit, especially for first-time homebuyers. Credit unions sometimes have more flexible down payment rules than banks. The key is to ask — many options exist, but they're not always advertised.
Putting down less than you'd prefer is not ideal, but it's often better than waiting years to save. A smaller down payment means higher monthly payments and PMI costs, but you build equity from the moment you buy, and you stop paying rent. Run the numbers for your specific situation: compare the cost of renting for another two years while you save versus buying now with a smaller down payment and paying PMI. Often, buying sooner is the better financial choice even if your down payment is smaller.
Frequently Asked Questions
Can I use a 401(k) or IRA withdrawal for a down payment?
Yes, but there are tax consequences. You can withdraw from a traditional IRA penalty-free if you're a first-time homebuyer (up to $10,000 lifetime), but you'll owe income tax on the withdrawal. A 401(k) withdrawal is more complicated and usually triggers both income tax and a 10 percent penalty unless you may have access to for a hardship exception. Speak with a tax professional before withdrawing retirement savings, because the tax bill can be substantial.
Does a larger down payment mean a better interest rate?
Usually yes. Lenders offer lower rates to borrowers who put down 20 percent or more, because the lender's risk is lower. The difference is often 0.25 to 0.5 percent, which sounds small but adds tens of thousands of dollars over a 30-year mortgage. However, the relationship between down payment and rate varies by lender and by your credit score, so compare offers from multiple lenders before deciding.
What if I want to put down more than 20 percent?
You can, and it's often a smart move if you have the savings. A larger down payment means a smaller loan, lower monthly payments, and you avoid PMI entirely. You also build equity faster. The only downside is that you're tying up more cash upfront, so make sure you have an emergency fund separate from your down payment savings before you commit extra money to the purchase.
Can I borrow my down payment from a family member?
Most lenders will not allow it, because borrowing increases your total debt and makes you riskier. However, a gift is different — if a family member gives you the money with no expectation of repayment, you can use it. You'll need a signed gift letter stating the money is a gift, not a loan. The lender will verify the gift with the family member, so be honest about the arrangement.
What if my down payment is not enough to reach 20 percent?
You'll pay PMI until you reach 20 percent equity through a combination of principal payments and home appreciation. You can also refinance once you have 20 percent equity, which removes PMI and may lower your rate if rates have dropped. Some lenders allow you to request PMI removal once you hit 20 percent equity; others require you to refinance. Ask your lender about their PMI removal policy before you sign the mortgage.
