Amortization Schedule Calculator

An amortization schedule breaks down each loan payment into its principal and interest components across the entire loan term. When you enter your loan amount, interest rate, and term length, the calculator applies the standard amortization formula to determine your fixed monthly payment. It then generates a complete month-by-month table showing how each payment is allocated. In the early years of a mortgage, the majority of each payment covers interest charges. As the loan matures, the balance shifts so that more of each payment reduces your principal. This pattern occurs because interest is calculated on the outstanding balance, which shrinks with every payment. The calculator produces a full table displaying the payment number, payment date, principal portion, interest portion, and remaining balance for every single month of the loan. Interactive charts illustrate how your principal and interest split changes over time, and a cumulative interest graph shows the total cost of borrowing at any point during the term. You can use this schedule to plan ahead by identifying milestones such as when you will have paid off half the principal or when your equity crosses a specific threshold. The schedule also helps you understand the true cost of extending or shortening your loan term. Comparing schedules for different scenarios lets you see how even small changes in rate or term dramatically affect total interest paid over the life of the loan.
