How it is calculated

  1. Payment = P × i ÷ (1 − (1 + i)^−n), rounded to the cent, where i = rate ÷ 12.
  2. Each month: interest = balance × i, rounded to the cent; the rest of the payment repays principal.
  3. The last payment pays exactly what is left, to end at 0.

Example

1,000 at 12% over 12 months: 88.85 a month; in month 1, 10.00 of interest and 78.85 of principal.

Good to know

  • Fixed rate and constant payments.
