How a down payment calculator works

A down payment calculator shows how much cash you put down on a home and how large a loan you will need, working from the home price and either a down payment percentage or a fixed dollar amount.

How do you calculate a down payment on a house?

Down payment amount = home price x down payment percent / 100, and the loan amount is the home price minus the down payment. For example, 20% down on a $300,000 home is a $60,000 down payment and a $240,000 loan. Estimates only, not financial advice.

How much down payment do I need to avoid PMI?

On a conventional loan, putting down at least 20% of the home price typically lets you avoid private mortgage insurance (PMI). Below 20%, lenders usually require PMI until you build enough equity. Confirm specifics with your lender.

Can I enter a dollar amount instead of a percentage?

Yes. This calculator links the percent and dollar fields both ways: type a percentage and it fills the dollar amount, or type a dollar amount and it fills the percentage. The loan amount updates automatically. Estimates only, not financial advice.
