What Your Down Payment Actually Needs to Be
Your down payment is the cash you hand over at closing, expressed as a percentage of the home's purchase price. If you buy a house for $300,000 and put down $60,000, that is a 20 percent down payment. The lender finances the rest through a mortgage.
The minimum down payment depends on the loan type. Conventional loans typically require 3 to 20 percent down. FHA loans allow as little as 3.5 percent. VA loans (for military members and veterans) often require zero down. USDA loans (for rural properties) also often require zero down. The lower your down payment, the higher your monthly mortgage payment and the more interest you pay over the life of the loan.
Down payment requirements also depend on your credit score, debt-to-income ratio, and the property itself. A lender may require 10 or 15 percent down if your credit is below 620 or if you have high existing debt. A property that appraises below the purchase price may force you to put more down to cover the gap.
Key Takeaways
- Down payment is the cash you pay upfront, calculated as a percentage of the home's purchase price, with minimums ranging from 0 to 20 percent depending on loan type.
- Putting down less than 20 percent on a conventional loan triggers private mortgage insurance (PMI), which adds to your monthly payment until you reach 20 percent equity.
- Your credit score, debt-to-income ratio, and the appraised value of the home all affect how much down payment a lender will require.
- Down payment calculators let you test different percentages against a specific purchase price to see how the amount changes your monthly payment and total interest cost.
How to Calculate the Dollar Amount
Start with the purchase price of the home you want to buy. Multiply that price by the down payment percentage you are considering. That product is the dollar amount you need to bring to closing.
Example: A house costs $350,000. You want to put down 15 percent. Multiply $350,000 by 0.15. The result is $52,500. That is your down payment.
If you do not yet have a specific house in mind, work backward from the cash you have available. If you have saved $40,000 and want to put down 20 percent, divide $40,000 by 0.20. The result is $200,000 — the maximum purchase price you can afford with that down payment percentage. You can then adjust the percentage down (to 15 or 10 percent) to see what purchase price becomes possible with your available cash.
Why 20 Percent Matters (and What Happens Below It)
Lenders treat 20 percent as a threshold. When you put down less than 20 percent on a conventional loan, the lender requires you to carry private mortgage insurance (PMI). PMI protects the lender if you default; it does not protect you. The cost is typically 0.5 to 1.5 percent of the loan amount per year, added to your monthly payment.
Example: You buy a $300,000 house with 10 percent down ($30,000). Your loan is $270,000. PMI might cost $1,350 to $4,050 per year, or roughly $112 to $337 per month. That amount stays on your bill until you have paid down the loan to 80 percent of the home's original purchase price — meaning you have built up 20 percent equity.
PMI does not last forever, but it can take years to reach 20 percent equity if you are putting down only 5 or 10 percent. Some borrowers pay PMI for the entire 30-year loan term because they never accumulate enough equity. FHA loans require mortgage insurance for the life of the loan if you put down less than 10 percent, even after you reach 20 percent equity.
Closing Costs Are Separate from Your Down Payment
Down payment and closing costs are two different line items. Your down payment is the equity stake in the home. Closing costs are fees paid to the lender, title company, appraiser, inspector, and other parties involved in the transaction. They typically range from 2 to 5 percent of the purchase price.
Example: A $300,000 home with a 20 percent down payment ($60,000) might have closing costs of $6,000 to $15,000. You need to bring both amounts to closing — the down payment plus the closing costs. Some lenders allow you to roll closing costs into the loan, but that increases your monthly payment and total interest paid.
Ask your lender for a Loan Estimate as soon as you are pre-approved. This document lists all closing costs and is required by federal law. It lets you see the full cash requirement before you make an offer on a house.
How Down Payment Affects Your Monthly Payment
A larger down payment lowers your monthly mortgage payment in two ways: it reduces the amount you need to borrow, and it eliminates or reduces PMI.
Example: A $300,000 house at 7 percent interest over 30 years. With 20 percent down ($60,000), your loan is $240,000 and your principal-and-interest payment is roughly $1,596 per month, with no PMI. With 10 percent down ($30,000), your loan is $270,000, your principal-and-interest payment is roughly $1,797 per month, and PMI adds another $150 to $200 per month — a total of roughly $1,950 to $2,000. The difference is $350 to $400 per month, or $4,200 to $4,800 per year.
Over 30 years, that difference compounds. A smaller down payment means you pay more in total interest and PMI. However, if you have limited cash and the alternative is waiting years to save more, putting down 5 or 10 percent and buying sooner may make sense — especially if home prices are rising in your market and you can refinance later when you have more equity.
Down Payment Assistance and Gift Money
If you do not have enough cash saved, several paths exist. Down payment assistance programs are offered by some state and local housing agencies, nonprofits, and employers. These programs may grant you money (which you do not repay) or a low-interest loan. Requirements and amounts vary widely by location and program.
Family members can also gift you down payment money. Most lenders allow gift funds, but they require a signed letter from the donor stating that the money is a gift and does not need to be repaid. The lender may also verify that the donor has the funds available. Gifts do not count as your own income or savings, so they do not hurt your debt-to-income ratio.
Some first-time homebuyer programs allow you to put down as little as 3 percent on a conventional loan, or they waive PMI requirements. These programs often have income limits or geographic restrictions. Your lender or a local housing counselor can tell you which programs exist in your area.
Using a Down Payment Calculator
Online calculators let you input a purchase price and test different down payment percentages to see the resulting loan amount, monthly payment, and total interest cost. These tools are free and available from most major lenders and financial websites.
A calculator shows you the trade-off between putting down more cash now and paying less interest over time. It also helps you understand how PMI affects your payment at different down payment levels. Run the numbers for 5, 10, 15, and 20 percent to see the full picture.
Keep in mind that calculator results assume a fixed interest rate and do not include property taxes, homeowners insurance, or HOA fees — all of which add to your actual monthly housing cost. Ask your lender or a real estate agent for estimates of these costs in your area so you can see your true monthly obligation.
Frequently Asked Questions
Can I use a gift from family for my down payment?
Yes. Most lenders allow gift funds, but they require a signed letter from the donor stating it is a gift and not a loan. The lender may also ask the donor to show proof that the money is available. Gifts do not count against your debt-to-income ratio.
What happens if the house appraises for less than the purchase price?
If the appraisal comes in low, your down payment percentage increases because the loan amount stays the same but the home's value is lower. You may need to bring more cash to closing, renegotiate the price with the seller, or walk away from the deal. This is why getting a pre-approval and appraisal early matters.
Can I put down less than 3 percent?
Conventional loans typically require at least 3 percent down. FHA loans allow 3.5 percent. VA and USDA loans often allow zero down if you meet their requirements. Some first-time homebuyer programs may offer lower percentages, but they are less common and have strict income or location limits.
Does a larger down payment help me get approved?
Yes. A larger down payment lowers the lender's risk, which can help you get approved if your credit score or debt-to-income ratio is borderline. It may also help you negotiate a better interest rate, though that depends on the lender and market conditions.
Should I put down 20 percent or invest the extra money instead?
That depends on your interest rate and investment returns. If your mortgage rate is 7 percent and you believe you can earn more than 7 percent in the stock market over 30 years, investing the extra cash may make financial sense. However, a larger down payment gives you peace of mind, eliminates PMI, and lowers your monthly payment — which matters if cash flow is tight.
