Loan Calculator

Estimate monthly loan payments, total interest and total repayment. Free to use online with no sign-up. Fast and mobile-friendly.

Use the standard amortization formula to estimate fixed payments for personal, auto or other installment loans.

Formula

Payment = P × r ÷ (1 − (1 + r)^−n), where r is the monthly rate and n is the number of payments.

Example

A loan with a lower rate or shorter principal produces less total interest.
