What is the Down Payment Calculator?

The down payment is the first big number in any home purchase, and it drives everything after it: your loan size, your monthly payment, and whether you'll pay mortgage insurance. This calculator turns a home price and a percentage into the two figures that matter — what you pay up front and what you borrow.

It runs in your browser and flags when you'd likely owe PMI.

What does this tool do?

Enter a home price and a down payment percentage, and it shows your down payment in money and the loan amount you'd need. Preset buttons cover common down payments from 3.5% to 25%, and if you go below 20% it notes that lenders usually require private mortgage insurance.

It's the quick way to see how much cash you need and how big your mortgage would be.

Tips

20% down avoids PMI and shrinks your loan — but don't drain every reserve; keep an emergency fund.
A bigger down payment can also earn a lower interest rate, saving more over the life of the loan.
Budget for closing costs on top — typically a few percent of the price — which this tool doesn't include.
Low-down-payment loans (e.g. 3.5%) get you in sooner but cost more monthly with PMI.
Pair with a mortgage calculator to turn the loan amount into a monthly payment.

Common mistakes to avoid

Forgetting closing costs

Fix: Budget a few percent of the price on top of the down payment.

Emptying savings for 20%

Fix: Keep an emergency fund; a slightly smaller down payment with reserves can be safer.

Ignoring PMI in the monthly budget

Fix: Under 20% usually adds PMI — factor it into affordability.

Stopping at the down payment

Fix: Feed the loan amount into a mortgage calculator for the real monthly cost.
