💡
By paying an extra $200 a month, you're effectively earning a guaranteed, tax-free return equal to your mortgage interest rate.

How We Calculate Mortgage Payoff

This calculator runs a true month-by-month amortization schedule to perfectly simulate exactly how banks apply extra principal payments.

Standard Payment (PMT)= P × [r(1 + r)^n] / [(1 + r)^n - 1]
Monthly Interest= Remaining Balance × (Annual Rate ÷ 12)
Principal Reduction= PMT + Extra Payment - Monthly Interest

Important: Ensure your loan servicer is applying your extra payments directly to Principal, not prepaying future interest.
