Estimate loan amortization

A fixed-rate amortizing loan uses equal monthly payments that cover interest and gradually reduce principal. Enter loan amount, annual interest rate and loan years to estimate monthly payment, total interest and total paid. It is useful for mortgages, auto loans, personal loans and debt planning.

Fixed-rate payment math

The estimate assumes one fixed interest rate, monthly payments and no extra principal payments.
