See how much you'll save by paying off your mortgage early
This calculator shows exactly how much time and interest you'll save by making extra payments toward your mortgage principal. Compare strategies — extra monthly, biweekly, or a lump sum — and see whether paying down your loan actually beats investing the same cash in the market.
Add a fixed amount to every monthly payment. Even $100/month on a 30-year loan can shave 3-5 years and save tens of thousands in interest.
Pay half your monthly payment every two weeks. Because there are 26 biweekly periods, you make one extra full payment per year — a "painless" acceleration.
A single one-time principal payment (e.g. tax refund, bonus, inheritance). Most effective early in the loan, when your payments are heavily interest-weighted.
Compares the guaranteed "return" from saving mortgage interest against investing the same extra dollars at a market rate. Your mortgage rate is the hurdle — beat it, and investing wins.
