The dollar amount depends entirely on the house price

A 3 percent down payment means you pay 3 percent of the purchase price upfront, and the lender finances the rest. On a $200,000 house, that's $6,000. On a $350,000 house, it's $10,500. On a $150,000 house, it's $4,500. The math is straightforward: multiply the house price by 0.03.

The reason this matters is that 3 percent is one of the lowest down payments available through conventional loans (loans not backed by the federal government). Most lenders require at least 3 percent, though some require 5 or 10 percent. Federal Housing Administration (FHA) loans allow down payments as low as 3.5 percent, and VA loans (for military members and veterans) sometimes allow zero down.

Key Takeaways

  • A 3 percent down payment on a $200,000 house is $6,000; on a $300,000 house it is $9,000.
  • Putting down only 3 percent means you borrow more money and pay more interest over the life of the loan.
  • With less than 20 percent down, you will pay private mortgage insurance (PMI), an extra monthly cost that protects the lender if you stop paying.
  • The total cost of buying a house includes the down payment plus closing costs (typically 2 to 5 percent of the price), which are separate from your down payment.

Why the down payment amount matters to your monthly payment

The down payment reduces the amount you borrow. If you put down 3 percent on a $200,000 house, you borrow $194,000. If you put down 20 percent, you borrow $160,000. A smaller loan means a smaller monthly mortgage payment, but it also means you pay more interest overall because you are borrowing more money for 15 or 30 years.

The difference adds up quickly. On a $200,000 house at current interest rates (which change daily), the monthly payment difference between 3 percent down and 20 percent down can be $200 to $300 per month. Over 30 years, that is tens of thousands of dollars in extra interest.

Private mortgage insurance: the hidden cost of a small down payment

Private mortgage insurance (PMI) is a monthly fee you pay when you put down less than 20 percent. It protects the lender, not you — if you stop paying the mortgage, PMI covers part of the lender's loss. On a 3 percent down payment, PMI typically costs 0.5 to 1.5 percent of the loan amount per year, divided into monthly payments.

On a $194,000 loan (3 percent down on a $200,000 house), PMI might cost $80 to $240 per month. You pay this in addition to your regular mortgage payment, property taxes, homeowners insurance, and possibly HOA fees. PMI does not build equity — it is pure cost. You can stop paying it once you have paid down the loan to 80 percent of the original house price, which typically takes 8 to 12 years.

Down payment versus closing costs: two separate expenses

The down payment is not the only money you need at closing (the day you sign the final paperwork and take ownership). Closing costs are separate fees for the loan itself, the title search, the appraisal, inspections, and other services. Closing costs typically run 2 to 5 percent of the house price.

On a $200,000 house, closing costs might be $4,000 to $10,000 on top of your $6,000 down payment. Some lenders allow you to roll closing costs into the loan, but that means you pay interest on them for 15 or 30 years. Others require you to pay them upfront. Ask the lender for a Loan Estimate — a form that shows all costs before you commit.

How to calculate your total cash needed at closing

Add your down payment and closing costs to find the total cash you need on closing day. If you are buying a $200,000 house with 3 percent down and closing costs of $6,000, you need $6,000 (down payment) plus $6,000 (closing costs) = $12,000 minimum.

Some buyers ask the seller to cover part of the closing costs as a negotiation point. This is called a seller concession. The seller agrees to pay some of your closing costs in exchange for a higher offer price. This does not reduce your down payment, but it reduces the cash you need to bring to closing. Ask your real estate agent or lender whether seller concessions are common in your area.

Programs that help with down payments and closing costs

If you do not have $12,000 or more saved, several programs exist. FHA loans require only 3.5 percent down instead of 3 percent, which saves money on the down payment itself but adds mortgage insurance costs. Some state and local governments offer down payment information programs that give grants (money you do not repay) or low-interest loans to first-time homebuyers.

Employer programs, credit unions, and nonprofits sometimes offer down payment help too. The terms vary widely — some are grants, some are forgivable loans (you do not repay if you stay in the house for a set number of years), and some are regular loans you repay. Contact your state housing finance agency or a local nonprofit to learn what is available where you live.

Frequently Asked Questions

Can I put down less than 3 percent?

Conventional loans typically require at least 3 percent. FHA loans allow 3.5 percent. VA loans (for may be able to access military members and veterans) often allow zero down. Some lenders have special programs for specific groups, but 3 percent is the standard minimum for conventional financing.

Does a larger down payment always mean a better deal?

A larger down payment lowers your monthly payment and eliminates PMI, but it also ties up cash you might need for emergencies or other goals. If you have $20,000 saved and the house costs $200,000, putting down 20 percent ($40,000) is not possible. Putting down 3 percent ($6,000) and keeping $14,000 for emergencies may be the smarter choice, even with PMI costs.

What happens if I cannot save the full down payment?

Explore down payment information programs in your state or county — many offer grants or forgivable loans. Ask your employer, credit union, or a local nonprofit about programs. You can also negotiate with the seller to cover closing costs, which reduces the total cash you need upfront.

Can I borrow the down payment from family?

Some lenders allow it, but most require a signed letter from the family member stating it is a gift, not a loan. If it is a loan, the lender counts it as debt and it affects how much you can borrow. Ask your lender about their gift letter policy before accepting money from family.
