The value of the monthly installment for the remaining payments: 66.500 JOD, including the principal, interest, and sales tax on the interest.
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: (represents the expected income): enter 0
IRR = 0.02812
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) = 32.791%
