How the down payment is calculated
The down payment is the home price multiplied by the down payment percentage. The loan amount is simply the remaining balance — the home price minus the down payment. A larger down payment lowers the loan amount and the loan-to-value ratio, which can reduce your rate and help you avoid mortgage insurance.
Down payment = Home price × (down payment % ÷ 100)Loan amount = Home price − Down payment- Home price
- Purchase price of the home
- Down payment %
- Share of the price paid up front
$400,000 home with 20% down
On a $400,000 home, a 20% down payment is $80,000 paid up front, which leaves a $320,000 loan to finance. At 20% down, the loan is 80% of the price, the threshold that typically lets buyers avoid private mortgage insurance.

Down payment FAQ
Do I really need 20% down?
No. Many loan programs allow much smaller down payments — some as low as 3% to 5%. A 20% down payment is simply the common threshold that lets buyers avoid private mortgage insurance and can qualify for better pricing.
Are closing costs part of the down payment?
No. Closing costs are separate from the down payment and typically add a few percent of the price on top. Budget for both when planning the cash you need to bring to closing.
