How This Calculator Works
APR reflects the true yearly cost of a loan by including upfront fees. The calculator finds the rate that makes the present value of your payments equal to the net amount you actually receive (loan minus fees).
Formula
Solve r where: net = PMT × [1 − (1+r)^−n] / r
Example
A $20,000 loan at 8% with $500 in fees over 5 years has an APR of about 9.1% — higher than the nominal rate.
Practical Use Cases
