Loan Calculator
Quick Answer
A loan calculator estimates your monthly payment for an amortising loan based on the amount borrowed, interest rate, and repayment term.
What Is Loan Calculator?
Loan Calculator is a free online calculator tools tool that calculate monthly loan payments, total cost and interest for any loan. A loan calculator estimates your monthly payment for an amortising loan — one where every payment covers both interest and a portion of the principal. You enter the loan amount, annual interest rate, and the term (number of payments, often monthly), and the tool returns the fixed payment amount, the total interest paid over the full term, and the total cost. Early payments are weighted toward interest because the outstanding balance is still high. Over time, as the principal shrinks, more of each payment goes toward the loan balance. This calculator does not account for fees or prepayment penalties, so your actual loan cost may differ slightly. Use it to compare offers: a lower rate or shorter term usually saves substantial interest, even if the monthly payment is higher. All math runs in your browser and your numbers are never uploaded. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits.
