- Choose the operation and enter every labeled input, keeping units and the time period consistent.
- Calculate, compare the worked example below and inspect any warnings.
- Change one assumption to compare another scenario; keep the model’s limits in view.
Formula & calculation method
Let P be principal, r the annual nominal rate divided by 1200 and n the number of months. Monthly payment = P × r ÷ [1 − (1 + r)^−n]. At zero interest, payment = P ÷ n.

A quick example
With a zero interest rate, a 12,000 loan over 12 months has a 1,000 monthly payment.

Questions about Loan Repayment
Does the loan repayment estimate include fees or insurance?
No. It models principal and interest only. Compare actual lender disclosures, including fees, payment dates, insurance and the distinction between nominal interest and APR.
Can I calculate a loan at 0% interest?
Yes. The principal is divided by the monthly payment count. The term must correspond to a whole number of months. The model does not add fees disguised as interest.
