Calculate mortgage payments given principal, interest and term. Reverse calculate any one variable given the other three.

Enter a down payment amount or percentage and let the calculator show how large a mortgage you require.

See how the monthly payment changes when you factor in additional monthly or annual loan costs such as PMI, HOA, taxes and insurance.

The calculator supports Fixed and Adjustable Rate Mortgages (ARM) loans with up to five changes in interest rates. Interest-only mortgages loans are also supported.

You can pay off your mortgage early with extra payments. Add one-off, monthly and annual extra payments. Choose up to ten additional extra payment amounts and payment periods and the calculator will show how much money you can save on the loan.

    Back in 2003 the original java applet calculator was instrumental in helping me discharge my mortgage. You're in good hands with this app.
