About Loan Calculator

Loan Calculator is a free tool that shows exactly what a loan will cost you. Enter the amount, interest rate, and term, and it instantly works out your monthly payment, the total interest you'll pay, when the loan is paid off, and a complete month-by-month breakdown.

What it does

Beyond the monthly payment, you get the full picture: total interest, total amount paid, payoff date, and a principal-versus-interest breakdown. The built-in amortization schedule shows every payment across the life of the loan — how much goes to principal, how much to interest, and the remaining balance each month.

See what extra payments save you

Add an optional extra monthly payment and the calculator shows how much sooner your loan is paid off and how much interest you save. It's an easy way to see the real impact of paying a little more each month.

Works for any loan

Because it's a general loan calculator, it works for personal loans, auto loans, student loans, and more — anything with a fixed amount, rate, and term.

Private and free
