A group of 3 women, one of them is renewed for the third time, the group is received a JOD1,500 loan from Tamweelcom, the share of each member being JOD 500, with a tenor of 15 months and at a declining interest rate/annual of 31.8% which is equivalent to fixed interest rate/annual of 18%.

3. How to calculate the effective interest rate (EIR) for the loan
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 = 0.02943
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) = 41.63 %
