What is Credit Card Interest?

Credit card interest is the amount charged by banks when you do not pay your full outstanding balance by the due date. Interest is usually calculated daily and added to your total balance.

How Credit Card Interest is Calculated

Credit card companies charge interest when the outstanding balance is not paid before the due date. The interest is usually calculated monthly based on the annual percentage rate (APR).

Formula:

Monthly Interest Rate = Annual Interest Rate ÷ 12

Interest = Balance × Monthly Rate × Number of Months

Credit Card Interest Calculation Example

Example scenario:

  • Credit Card Balance = ₹20,000
  • Annual Interest Rate = 36%
  • Repayment Period = 6 months

Monthly Rate = 36% ÷ 12 = 3%

Interest = ₹20,000 × 3% × 6

Total Interest = ₹3,600

Total Payment = ₹23,600

Using this **credit card interest calculator**, you can estimate how much interest you will pay if the balance is carried forward.
