Amortization Calculator

Calculate the monthly payment, total interest, and full payoff schedule of an amortized loan such as a mortgage or car loan.

About the Amortization Calculator

The monthly payment uses the standard amortization formula: PMT = P × i / (1 − (1+i)−n), where P is the loan amount, i the monthly rate and n the number of payments. Each payment pays the month's interest first; the remainder reduces the principal, so the interest share shrinks every month.
