What Is APR? Understanding the True Cost of Your Loan

APR vs Interest Rate: What Is the Difference?

The interest rate is what the lender charges on the principal amount. The APR (Annual Percentage Rate) includes the interest rate plus all additional costs — processing fees, documentation charges, insurance premiums — expressed as a yearly percentage.

Why APR Matters More Than Interest Rate

Two loans can have the same interest rate but wildly different APRs. Consider this example:

  • Loan A: 12% interest, 3% processing fee → APR = 14.8%
  • Loan B: 12.5% interest, 0.5% processing fee → APR = 13.2%

Loan B has a higher interest rate but is actually cheaper because of lower fees. APR reveals the true cost.

How to Calculate APR

APR accounts for the total cost of borrowing over the loan tenure. The formula considers:

  1. The principal amount you receive (after fee deductions)
  2. All monthly EMI payments
  3. The effective annual rate that makes these equal

  • Documentation charges
