What Is a Payment Calculator?
A payment calculator estimates how much you may need to pay for a loan or financing plan. It uses the loan amount, interest rate, loan term, payment frequency, fees, and optional extra payments to calculate the payment per period, total interest, total repayment, payoff time, and amortization schedule.
This free online payment calculator is useful for personal loans, installment loans, car payments, business loans, debt repayment planning, and general finance comparisons. It helps you understand the real cost of borrowing before you accept a loan offer.

How Payment Calculations Work
Most fixed-rate payment calculations use amortization. At the beginning of repayment, more of each payment may go toward interest. Later, more of the payment goes toward principal. This calculator estimates that repayment structure and shows the balance over time.
Payment Formula Explained
The payment formula estimates the fixed payment needed to repay a balance over a selected term. The calculator also includes optional loan fees and extra payments so you can compare repayment scenarios.
