The effective interest rate (EIR) = (1+IRR)12 - 1
The Internal rate of return (IRR) calculated using Microsoft Excel by using the equation of IRR:
Value field: enter all the cash flows (plus and minus)
Guess field: (represent the expected income) enter 0
IRR = 0.01930
Which represent the Monthly Effective rate
The effective interest rate (EIR) calculated by substitute the IRR in the following equation:
The effective interest rate (EIR) = (1+IRR)12 - 1
The effective interest rate (EIR) = 34.692%
