Monthly r = nominal annual rate ÷ 12. Payment = P × r ÷ (1 − (1+r)^−n); at 0%, P ÷ n. The annuity uses floating-point math; regular payment is rounded to cents. Monthly interest rounds half up; the final payment clears the balance and may differ. Cent rounding can shorten payoff for small amounts. No fees, extra payments, dates, insurance or tax.

CurrencyTwo decimal places; no conversion.

How it works & useful details

Formula & assumptions

A fixed nominal annual interest rate is divided by 12. The annuity formula estimates equal monthly payments; monthly interest is then rounded to cents on the remaining principal. The final payment clears the balance and may differ. This is a monthly model, not a lender quote or APR calculation. It excludes fees, daily accrual, dates, insurance, tax and extra payments. Principal must be positive; terms are 1–600 months. Inputs that cannot amortize at cent precision are rejected.
