About Loan Amortization

Builds a fixed-payment amortization schedule under nominal APR and a chosen payment frequency. Extra payments (fixed each period or one-off) go directly to principal and shorten payoff time and total interest.

Formulas

  • Rate per period: i = APR / m, periods: N = years × m, where m is payments per year.
  • Payment (PMT): PMT = P·i / (1 − (1+i)^{-N}) (if i=0, then P/N).
  • Each period: interest = balance · i; principal = PMT − interest.

If the custom payment is ≤ interest for a period, the balance grows (negative amortization), which this tool will flag as invalid.
