Frequently asked questions
Any fixed-rate installment loan with equal monthly payments — personal loans, student loans, small business loans, and similar. It does not handle variable rates, interest-only periods, or balloon payments.
No. The calculator works from the loan amount and rate only. If your lender charges origination fees, late charges, or insurance, the true total cost will be higher than shown.
When the rate is zero, the formula reduces to M = loan amount / number of payments. The result is the principal divided evenly over the term, with zero interest.
