Loan Amortization Calculator & Schedule
Loan amortization structures monthly payments so that every installment covers accrued interest and reduces the principal balance. Use this calculator to analyze your mortgage or loan payoff timeline.
Frequently Asked Questions
Why do early payments go mostly toward interest?
Interest is charged against the remaining balance. Because the initial principal balance is largest at the beginning, the required monthly interest charge is highest early on.
