A client received a JOD 2,500 loan from Tamweelcom, with a tenor of 20 months and at a declining interest rate/annual of 0% which is equivalent to fixed interest rate/annual of 0%.
1- What is the total interest rate paid for the loan?
Total interest rate for the loan = 0 JOD
Stamps duty on the Contract = 9 JOD
2- What is the monthly payment for the loan (principal, interest and sales tax on interest)?
First month payment amount: 125 JOD (Principal 125 JOD, interest 0 JOD and sales tax on interest 0 JOD)
The remaining monthly payments amount: 125 JOD (Including principal payment, interest and sales tax on 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: (represent the expected income) enter 0
IRR = 1.866
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) = 1.796%
