How to use this mortgage calculator
Start with the home price, then set your down payment as a percentage of that price. A 20% down payment is conventional because it usually lets you avoid private mortgage insurance (PMI), but many loan programs accept far less down. Enter the interest rate you've been quoted — even a fraction of a percent compounds across 30 years.
The large green figure is your monthly principal and interest payment. The PITI figure below it adds estimated property taxes and home insurance so you see the full monthly cost of owning the home.
What changes your payment the most?
Three inputs matter most: home price, interest rate, and loan term. Over 30 years on a typical loan the total interest can rival the price of the home itself — which is why a lower rate or a shorter term can save tens of thousands. Move the sliders to compare scenarios side by side.
