If you are planning to take a loan, then it is important for you to know the concept of ROI and APR. A clear understanding of these terms will empower you to compare between lenders and various loan offerings
Let us understand this further and how it’s calculated.
What is ROI?
The Rate of Interest is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned. The interest rate does not include any other fees charged for the loan
What is APR?
The Annual Percentage Rate is the total annual cost of your loan expressed in percentage. It includes the yearly rate of interest charged by the lender and other fees levied such as processing fees, administrative charges, loan insurance costs, etc.
How are the ROI and APR calculated?
The ROI is set by the lender and is expressed as a percentage of the principal.
The formula to calculate the total amount payable (principal plus simple interest) is
A = (P(1+rt)), where
As an example, let’s say Alok has borrowed Rs 5 Lakh for a personal loan at anannual interest rate of 24% with a repayment tenure of 3 years. Alok also paid an upfront processing fees of 2% of the loan ie Rs 10,000.
Alok’s total amount payable using the above formula is [(500000 x (1+0.24 x 3)] = 8,60,000
The formula to calculate the total interest amount payable is Total amount due – Principal (A-P) which means in this case 8,60,000 – 5,00,000 = 3,60,000
In this case, the total amount paid by Alok is Rs 8,70,000 (500,000 towards principal + Interest of Rs 3,60,000 + Processing fee of Rs 10,000)
Now, let’s take the similar example of Alok to calculate the APR.
Interest payable as calculated above is 3,60,000
The formula used to calculate APR is: [{(Interest + Other Fees) / Principal} / Duration of the loan in years] x 1 x 100
so the APR is {(3,60,000 + 10,000) / 5,00,000} / 3] x 1 x 100 = 24.67%
As we see, Alok’s actual loan cost is coming at 24.67%, which is higher than the annual interest rate of 24 %
To summarise the APR of 24.67 % is the same as paying a ROI of 24% with a 2% processing fee.
Other Important Aspects to Consider
Bottom Line
It is important to remember the distinction between ROI and APR and treat them separately. Most people make the mistake of just checking the ROI (or treating both as the same) and using it as the main factor to calculate their cost of borrowing. As you now know, that is not the case.
Using the Annual Percentage Loan not only gives you a better idea on the cost of the loan beforehand, but also helps you choose the lender wisely and get the best loan deals. Therefore, whenever you apply for a loan ensure you confirm the APR with your lender before signing the loan documents
