Free Mortgage Payoff Calculators That Show Real Numbers

AmortWise gives you two free calculators that show exactly how your mortgage payoff changes: one for biweekly payments and one for extra payments. Both run on standard amortization math, require no registration, and have no hidden charges. Type in your loan details and the numbers update instantly — payoff date, total interest, and what you would save.

Biweekly Mortgage Calculator

See what happens when you pay half your monthly payment every two weeks: your new payoff date, the interest you save, and a year-by-year balance comparison against the standard schedule.

Extra Payment Calculator
