Amortization Schedule Calculator
Visualize how every payment is applied to principal and interest. Experiment with extra payments to see how quickly you can get debt-free and how much interest you can save.
How extra payments help
Every additional dollar goes straight to principal, cutting interest and shortening your payoff timeline. Even $100/month can save tens of thousands over a 30-year loan.

Line chart shows how the remaining balance shrinks each month with your current plan. Add extra payments to see the curve drop faster.
Interest vs. Principal
Early payments mostly cover interest. As the balance drops, more of each payment goes toward principal.
