What it does

A simple loan calculator with three inputs and three outputs. Enter the amount borrowed, the APR, and the term in years. See the monthly payment, the total amount paid, and the total interest. No ads in the middle of the tool, no jargon, no tricks.

Useful for any fixed-rate installment loan where you just want a fast answer — loaning money between family, estimating a personal loan, or doing a quick sanity check on a lender’s quote.

Frequently asked questions

Does this calculator account for origination fees?
No. Add any origination fee to the principal before calculating. For example, a $10,000 loan with a 3% origination fee becomes $10,300.
