Free Loan Amortization Schedule Generator
See exactly how much of each payment goes to principal vs. interest over the life of your loan. An amortization schedule is a complete table of periodic loan payments that shows the amount going toward principal and the amount going toward interest, along with the remaining balance after each payment. This is essential for understanding the true cost of borrowing and planning your debt repayment strategy.
How Amortization Works
In a standard amortizing loan, each payment is the same amount each month, but the composition changes over time. Early payments consist mostly of interest with a small amount going toward principal. As the principal balance decreases, the interest portion shrinks and more of your payment goes toward paying down the principal. This process continues until the loan is fully paid off at the end of the term. Our calculator generates a full schedule showing this breakdown for every payment period.

Why Use an Amortization Schedule
Homebuyers use amortization schedules to understand how their mortgage payments are applied and how extra payments could save interest. Financial planners use them to model debt scenarios for clients. Students learning about finance can visualize how loan mathematics work in practice. By seeing the full schedule, you can make informed decisions about loan terms, extra payments, and refinancing options.

What Can Change The Real Schedule
Actual loan schedules can differ because of payment timing, escrow changes, extra principal payments, fees, variable rates, rounding rules, late payments, refinancing, or lender-specific amortization methods. Use this table to understand the structure of repayment, then compare it with your lender's official documents.
Quick Answer
An amortization schedule shows how each payment is split between interest and principal. Early payments usually pay more interest; later payments pay more principal as the balance declines.
