Loan Calculator

Calculate your monthly loan payment, total interest paid, and see a full amortization schedule. Works for personal loans, auto loans, student loans and more.

Loan Payment Formula

Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1] where P is principal, r is monthly rate, and n is number of payments.

A lower interest rate or longer term reduces monthly payments, but a longer term means paying more total interest. Use this calculator to find the right balance for your budget.
