How to use the loan calculator
Enter how much you want to borrow, the annual interest rate, and the term in years. The calculator returns your fixed monthly payment along with the total interest and the total amount you will have paid by the end of the loan. Everything is computed in your browser.
Why the total cost matters as much as the payment
It is easy to focus only on whether the monthly payment fits your budget, but the total interest tells the real story. Stretching a loan over a longer term lowers each payment yet can dramatically increase what you pay overall, because interest accrues for more months. Comparing the total-interest figure across different terms is often more revealing than comparing the monthly amounts.
Trying different scenarios
Because the result updates instantly, this tool is well suited to what-if comparisons. Try the same amount over 3, 5, and 7 years, or compare two interest rates, and watch how the monthly payment and total interest move in opposite directions. That trade-off — lower payments versus lower total cost — is the central decision in any borrowing choice. The figures here are estimates for planning; your lender’s official quote is the binding one.
