How the loan payment calculator works

This calculator uses the standard amortization formula to compute your fixed monthly payment given a principal, annual interest rate, and loan term. Each payment covers the accrued interest first; the remainder reduces the outstanding principal. Over time a larger share of each payment goes toward principal, which is why early payments feel mostly like interest.

The total interest figure shows the true cost of borrowing beyond the principal. A longer term lowers the monthly payment but raises total interest paid; a shorter term does the opposite. Use this tool to compare scenarios before committing to a loan.

FAQ

Does this work for mortgages? Yes. A fixed-rate mortgage follows the same amortization math. Enter your home loan amount, the quoted annual rate, and term in years.

What about extra payments or adjustable rates? This calculator covers fixed-rate loans only. Extra principal payments or rate adjustments would require a more detailed schedule.

Is my data sent anywhere? No. All calculations happen locally in your browser.
