Introduction
When applying for a personal loan, home loan, credit card, or other borrowing product, you may come across two important terms: interest rate and Annual Percentage Rate (APR). Although they are closely related, they do not mean the same thing.
The interest rate tells you how much interest a lender charges on the amount you borrow. APR gives you a broader picture of the annual borrowing cost by including the interest rate and certain additional loan charges, depending on the loan and applicable rules.
Understanding the difference between interest rate vs APR can help you compare loan offers, understand repayment costs, and make informed borrowing decisions.
What Is an Interest Rate?
An interest rate is the percentage a lender charges a borrower for using borrowed money. It is usually expressed as an annual percentage of the outstanding loan amount.
For example, if you borrow ₹1,00,000 at an annual interest rate of 10%, the interest rate helps determine how much interest you pay over the loan tenure. The actual amount depends on factors such as the repayment schedule, outstanding principal, and loan calculation method.
Types of Interest Rates
-
Fixed interest rate: Remains unchanged for the agreed period, subject to the loan terms.
-
Floating interest rate: Can change according to the applicable benchmark or lending terms.
-
Simple interest: Calculated on the original principal amount.
-
Compound interest: Calculated on the principal and accumulated interest, where applicable.
What Is APR (Annual Percentage Rate)?
APR stands for Annual Percentage Rate. It represents the annualised cost of borrowing and generally considers the interest rate along with certain applicable fees and charges.
For example, a loan may have a 10% interest rate but a higher APR if the lender also charges an upfront processing fee. This means the loan's overall borrowing cost may be higher than the interest rate alone suggests.
APR is useful when comparing borrowing options because it can provide a more complete picture of the cost of credit. However, the charges included in APR calculations can vary by product, jurisdiction, and applicable calculation rules.
What Can APR Include?
Depending on the loan and applicable rules, APR may account for:
-
The interest charged on the loan.
-
Certain processing or origination fees.
-
Other mandatory charges associated with obtaining the credit.
-
The timing of payments and applicable repayment terms.
Not every fee is necessarily included. Always review the lender's loan agreement and Key Facts Statement (KFS), where applicable, to understand the disclosed APR and total borrowing cost.
