About this loan amortization calculator
The Loan Amortization Calculator turns a loan amount, annual interest rate, and term into a monthly payment and a complete amortization schedule. For every payment it shows how much goes to interest, how much reduces the principal, and the remaining balance, so you can see how early payments are mostly interest while later ones are mostly principal. You also get the total interest and total amount paid over the life of the loan, and you can copy the whole schedule as CSV. All calculations run locally in your browser and nothing is uploaded.
