Start with what you can actually afford to save

A down payment is the money you put toward a house or car at the time you buy it — the rest comes from a loan. The amount you need depends on three things: what the lender requires, what you can save without emptying your emergency fund, and what makes sense for your monthly payments afterward.

Begin by looking at your savings. A down payment should not be money you need for rent, food, or unexpected costs. If you have $8,000 saved and $3,000 of that is your emergency cushion, you realistically have $5,000 to work with. That is your ceiling, not your goal.

Next, find out what lenders in your area actually require. This varies by loan type and by lender. A conventional mortgage might ask for 10 to 20 percent of the home price. An FHA loan (a federal program for first-time buyers) might accept 3.5 percent. A car loan might require 10 to 15 percent. Call three lenders and ask what they need from someone in your situation — do not guess based on what you read online.

Key Takeaways

  • Your down payment comes from savings you can afford to part with after keeping an emergency fund of three to six months of expenses.
  • Lenders set minimum down payments that vary by loan type, so you need to call and ask what your specific lender requires, not assume a percentage.
  • A larger down payment lowers your monthly payment and the total interest you pay, but only if it does not leave you unable to handle emergencies.
  • Putting down less than 20 percent on a house usually means paying mortgage insurance, which adds to your monthly cost but lets you buy sooner.
  • The right down payment balances what the lender requires, what you have saved, and what keeps your monthly payment manageable on your actual income.

How lenders decide what they will accept

Different types of loans have different rules. A conventional mortgage — a loan from a bank or mortgage company that is not backed by the government — often wants 15 to 20 percent down. An FHA loan, backed by the Federal Housing Administration, might accept 3.5 percent. A VA loan, for military members and veterans, sometimes requires zero down. A car loan might ask for 10 to 15 percent, though some lenders will go lower.

The lender's rule is not a suggestion — it is a requirement before they will give you money. If a lender says they need 10 percent and you offer 5 percent, they will say no. Call the lender directly and ask: "What is the minimum down payment you require for someone with my credit score and income?" Write down the answer and the lender's name.

If you cannot meet the minimum, you have two choices: save longer, or find a different lender with a lower requirement. Some lenders specialize in smaller down payments. Some programs exist specifically to help people with lower savings — your local housing authority or a nonprofit housing counselor can tell you which ones operate in your area.

The math between down payment size and monthly cost

A larger down payment means a smaller loan, which means a smaller monthly payment. If a house costs $200,000 and you put down $20,000, you borrow $180,000. If you put down $40,000, you borrow $160,000. The second option costs less per month.

But there is a catch: if you put down less than 20 percent on a house, the lender adds mortgage insurance to your monthly payment. This is insurance that protects the lender if you stop paying, not insurance that protects you. It typically costs 0.5 to 1 percent of the loan amount per year, split across your monthly payments. On a $180,000 loan, that might add $75 to $150 per month.

This means putting down 10 percent instead of 20 percent does not always double your monthly payment — the difference is usually smaller. But it does make the payment higher than it would be with 20 percent down. You need to run the actual numbers with a lender to see whether the smaller down payment still fits your budget.

How to calculate what you can afford to put down

Write down three numbers. First, your total savings right now. Second, the amount you need to keep as an emergency fund — most people aim for three to six months of expenses, though even one month is better than nothing. Third, subtract the second from the first. That is your available down payment pool.

Next, call a lender and ask what they require as a minimum. If your available pool is larger than the minimum, you have choices. If it is smaller, you need to either save longer or look for a lender with a lower requirement.

Once you know the minimum, decide whether to put down exactly that amount or more. Putting down more lowers your monthly payment and removes mortgage insurance (on a house). But it also uses money you could keep for emergencies, home repairs, or life changes. There is no single right answer — it depends on your job stability, whether you have family nearby to help in a crisis, and how comfortable you feel with less cushion.

Down payment help from government programs and nonprofits

Some programs help people save for a down payment or provide money toward one. These vary by location and by what you are buying. A few examples: some cities have down payment information for first-time homebuyers, some employers offer down payment help as a benefit, and some nonprofits run matched savings accounts where they add money to what you save.

To find what exists in your area, contact your local housing authority, call 211 (a referral line that connects you to local programs), or search "[your city] down payment information." Be specific about what you are buying — a house program will not help with a car, and vice versa.

These programs often have requirements: you might need to be a first-time buyer, live in a certain area, or have income below a certain level. But they are worth checking, because the money is real and does not have to be repaid.

What happens if you do not have enough saved yet

If your available savings are below what lenders require, you have three paths. The first is to keep saving. Set a monthly savings goal and a target date. If you need $10,000 and can save $300 a month, you will reach it in about 33 months. Write that date down and track your progress.

The second path is to find a lender with a lower requirement. Some lenders accept smaller down payments than others. Some specialize in people with limited savings. Call at least three lenders and ask what they require — do not assume they are all the same.

The third path is to look for a down payment information program in your area. These are real programs with real money, though they have requirements and may take time to process. A housing counselor or your local 211 line can tell you which ones are currently open.

Common mistakes when choosing a down payment amount

The biggest mistake is putting down every dollar you have. If you buy a house with a $50,000 down payment and then your car breaks down or you lose hours at work, you have no cushion. You end up borrowing on credit cards or missing payments. A down payment should not leave you fragile.

The second mistake is assuming all lenders have the same requirement. They do not. If one lender says they need 15 percent down, another might accept 10 percent. It is worth calling around.

The third mistake is not asking about mortgage insurance. Some people put down 15 percent thinking they are avoiding insurance, then discover they still have to pay it because their lender requires 20 percent. Ask directly: "If I put down [amount], will I pay mortgage insurance?"

Frequently Asked Questions

Can I borrow my down payment from someone else?

Some lenders allow it if the money is a gift and comes with a signed letter saying it does not have to be repaid. Other lenders do not allow borrowed money at all. Ask your lender before you accept a loan from family or friends. If they say no, borrowing anyway and hiding it can disqualify you later.

What if I put down more than the lender requires?

You can always put down more than the minimum. This lowers your monthly payment and removes mortgage insurance if you hit 20 percent. But make sure you keep enough in savings for emergencies — do not empty your account to reach 20 percent.

Does a bigger down payment help my credit score?

No. Your credit score is based on your payment history and how much debt you carry, not on how much you put down. A larger down payment does not build credit. Making your monthly payments on time does.

Can I use my retirement account for a down payment?

Some retirement accounts allow withdrawals for a first home purchase, but this usually comes with taxes and penalties. Talk to the company that holds your account before you withdraw anything. A financial counselor can help you understand the cost.

What if the house costs more than I expected?

Your down payment is a percentage of the actual price, so if the house costs more, your down payment amount goes up too. If you planned to put down 10 percent of a $200,000 house ($20,000) but the house costs $250,000, 10 percent is now $25,000. Make sure you know the final price before you commit to a down payment amount.
