Is it too good to be true?
In this guide, we’ll break down everything you need to know about cc APR, how zero percent interest works, and highlight the top-rated no-interest credit cards in 2025. Whether you’re trying to pay off debt, finance a big purchase, or just looking for a smart credit card move, this article will help you make the right decision.
💳 What is CC APR? (Credit Card APR Simplified)
APR, or Annual Percentage Rate, is the interest rate you’ll pay on any balance you carry on your credit card after your statement due date. Simply put:
-
If you pay your balance in full every month → You typically won’t pay any interest.
-
If you carry a balance → You’ll be charged a percentage (APR) on that amount.
CC APR is how lenders make money from your revolving credit account.
🧮 How Is Credit Card APR Calculated?
APR is expressed as a yearly rate, but it’s applied daily. The formula used is:
Daily Periodic Rate = (APR ÷ 365)
Interest Charge = Daily Periodic Rate × Average Daily Balance × Days in Billing Cycle
For example, if you have a credit card APR of 18% and an average balance of ₹50,000 over 30 days:
-
Daily Rate = 0.0493%
-
Interest = ₹50,000 × 0.000493 × 30 = ₹739.50
That’s how much you’ll pay just in interest!
