APR Calculator

Estimate nominal APR including upfront finance charges for a fixed monthly-payment loan.

How It Works

Net proceeds=contract principal−upfront charges. Solve the monthly discount rate matching net proceeds to scheduled payments; estimated APR=12×monthly rate.

Equal monthly periods, no irregular dates or balloon payment. This is a simplified cash-flow APR estimate, not a full Regulation Z disclosure calculation.
