Loan calculator with a full amortization schedule
Enter your loan amount, annual interest rate, and term in years, then click Calculate. You'll get your estimated monthly payment plus a complete amortization schedule showing how every payment splits between principal and interest — and how your balance falls to zero over the life of the loan.
How to use this calculator
Enter the total amount you plan to borrow. Input the annual interest rate offered by your lender. Set the loan term in years (for example, 30 for a typical mortgage). Click Calculate to see your monthly payment, total interest, total cost, and the month-by-month amortization table. Switch the table between Yearly and Monthly views, and use Export CSV to download the full schedule.
Understanding your amortization schedule
An amortization schedule lists every scheduled payment across the life of the loan. Each row shows the payment amount, how much goes to interest, how much reduces the principal, and the remaining balance afterward.
Early in the loan, most of each payment goes toward interest because interest is charged on a larger outstanding balance. As the balance falls, the interest portion shrinks and more of each payment reduces the principal. This is why extra payments made early save the most interest.
The monthly payment shown covers principal and interest only. It does not include property taxes, homeowners insurance, HOA dues, or mortgage insurance, so your real-world payment may be higher.
Why the amortization table matters
Seeing the full schedule helps you compare loan terms, understand how much interest you'll actually pay, and decide whether extra payments are worth it. Exporting the schedule to CSV lets you keep a record or run your own what-if analysis in a spreadsheet.
