About this tool

A personal loan's sticker rate hides two things: the monthly-payment arithmetic and the origination fee that quietly raises your true cost. This calculator handles both. Enter amount, rate and term to get the standard amortized payment (M = P × r(1+r)^n / ((1+r)^n − 1)), total interest, and total repaid — then add a typical origination fee and the tool shows what you actually receive, recomputes the fee-adjusted effective APR the way fee-inclusive disclosure works, and splits your first payment into interest and principal. The APR-versus-rate note explains why a 10% loan with a 5% fee costs meaningfully more than 10%. All math runs in this page and nothing is transmitted anywhere. It is an educational estimate for comparison shopping — not a lender offer and not professional financial advice.
