Build loan payoff schedules with principal, interest, and balance details.

Amortization-Calc is a web calculator for estimating fixed loan payments and generating a payment-by-payment amortization schedule. It breaks each payment into principal and interest, shows the remaining balance over time, and includes explanatory FAQ material for common loan-amortization questions.

Why it stands out

  • Shows the full repayment schedule rather than only a monthly payment estimate.
  • Breaks results into principal, interest, and balance for every payment.
  • Groups long schedules by year, which is useful for 15- or 30-year loans.
  • Covers several loan contexts from one site, including refinance and business loans.
  • Pairs the calculator with plain-language explanations of amortization concepts.

Good to know

  • Calculations are most reliable for standard fixed-rate amortizing loans; adjustable-rate loans need recalculation when the rate changes.
  • The schedule is an estimate, not a lender quote or a substitute for the loan agreement.
  • Past payments are not reconstructed automatically; for an existing loan, users must enter the current balance and remaining term.
  • Lender-specific fees, taxes, insurance, and prepayment penalties are not captured by the basic amortization inputs.

Under the radar: For a loan already in progress, use the current outstanding balance and the number of payments left rather than the original loan amount and original term.
