An example

With 10,000.00 USD at a fixed 12 % nominal annual rate for 12 months, without extra payments, the ordinary installment is 888.49 USD; the interest totals 661.86 USD and the total 10,661.86 USD. The last installment is adjusted to 888.47 USD.

Calculation assumptions

The nominal annual rate is fixed; it is divided by 12 for the monthly interest.
Paid at the end of each month. Interest uses the balance at the beginning of the month.
Extra payments go to principal after the installment and end upon settlement.
Installment and interest are rounded to the minor currency unit of the chosen currency; the final installment may vary.
