How Does Credit Card Interest Work?

Credit card interest is usually calculated on a daily basis using the daily periodic rate.

Here’s how it works:

1. The annual interest rate (APR) is divided by 365 days
2. Interest is applied daily to your outstanding balance
3. If you don’t pay the full amount, interest keeps adding up

This process is called compounding, and it can significantly increase your debt over time.

Credit Card Interest Formula

The interest is generally calculated using this formula:$$Interest = Balance \times \frac{APR}{365} \times Days$$Interest=Balance×365APR​×Days

Where:

• Balance = Outstanding amount
• APR = Annual Percentage Rate
• Days = Number of days the balance is unpaid

The calculator automatically applies this formula to give you accurate results.
