Effective interest rate calculator
The effective interest rate accounts for fees and shows the real annual cost of the loan, not just the advertised nominal rate.
This calculator finds the rate that sets the net present value of the loan’s cash flows to zero (IRR) — the same principle used in standardised Norwegian effective-rate calculations.
