Loan Calculator

Free loan repayment calculator. Calculate monthly loan payments, total interest, and full amortization for any personal or auto loan.

How the Loan Calculator works

The calculator uses the standard amortization formula to determine a fixed monthly payment that pays off both principal and interest over the loan term. Each payment covers the interest accrued that month, with the remainder reducing the principal.

Formula

M = P × r(1+r)^n / ((1+r)^n − 1)
