This tool uses the standard equal-payment (amortizing) method and is for reference only. Your actual payment may differ due to grace periods, fees, rate changes or day-count conventions — always rely on your lender's official schedule.

Understanding every payment is the first step to borrowing smart

Whether it's a mortgage, car loan or personal loan, most use the amortizing method: you pay the same amount each month, but the split between interest and principal shifts over time — heavy on interest early, heavy on principal later. This loan amortization calculator lays that whole process out so you can see exactly how much interest you pay and how the balance falls month after month.

Total interest is often more than you think

On a 30-year mortgage, total interest can approach or even exceed the amount borrowed. Enter your loan amount, rate and term and the calculator instantly shows total repayment and total interest, plus the crossover point where remaining balance meets cumulative interest. See the Wikipedia article on amortization for the underlying math.

A little extra each month can shave off years

Enter an amount in the extra monthly payment field and the calculator compares paying off with and without it, telling you how much interest you save and how many months earlier you're debt-free. Even a small extra payment compounds into big savings over time. Pair this with our compound interest calculator and rent vs buy calculator to plan your bigger financial decisions.
