About Loan Calculator

Loan repayment calculator — mortgage, car, personal loan. Enter principal, interest rate, and term; see monthly payment, total interest paid, and an amortisation schedule.

The monthly payment formula assumes a fixed-rate loan with monthly compounding (the standard for US mortgages and most car loans). Adjustable-rate mortgages start with this monthly payment but recalculate periodically based on the index rate — the schedule shown here is for the introductory rate.

Total interest paid is often eye-opening — a 30-year $400k mortgage at 6.5% pays ~$510k in interest over the life of the loan. The amortisation schedule shows how each early payment is mostly interest, gradually shifting to principal.
