Amortization Schedule
Watch every dollar of principal and interest unfold across the life of your loan.
About the Amortization Schedule
This amortization schedule provides a detailed, month-by-month breakdown of any fixed-rate loan for up to 360 payments. Enter your loan amount, annual interest rate, loan term in years, first payment date, and optional extra monthly payment to generate a complete payment table showing each month's payment number, date, beginning balance, total payment, principal, interest, extra payment, and remaining balance. Two embedded charts visualize the loan balance over time and the principal-versus-interest breakdown per payment. Conditional formatting highlights when the loan reaches a zero balance, and data validation ensures all inputs fall within valid ranges. Use it alongside the Mortgage Calculator for a complete home-loan analysis.
