ℹ️ About Amortization Calculator
Enter a loan amount, an annual interest rate and a term in years, and the Amortization Calculator builds the full month-by-month repayment schedule. It reports the level monthly payment, total paid, total interest and the projected payoff month, then lists every installment split into principal, interest and remaining balance. Borrowers use it to see how heavily the early payments go to interest. The schedule exports to CSV or prints, and all of it is calculated in your browser.
💡 Use Cases
