### Formula and Example

The formula for calculating credit card interest can be expressed as:

**Interest for the Month = (Average Daily Balance) x (Daily Periodic Rate) x (Number of Days in Billing Cycle)**

Here’s an example of how to calculate credit card interest for a billing cycle:

Let’s say you have a credit card with the following details:

- Outstanding balance at the beginning of the billing cycle: $1,000
- Annual percentage rate (APR): 18%
- Billing cycle: 30 days

**-Calculate the daily periodic rate**:

Daily Periodic Rate = (18% / 365) = 0.0493% (rounded to four decimal places)

**-Calculate the average daily balance.**

For this example, let’s assume your balance remained constant at $1,000 for the entire billing cycle: Average Daily Balance = $1,000

**-Calculate the interest for the month**:

Interest for the Month = ($1,000) x (0.000493) x (30) = $14.79

So, in this example, the interest charged on your credit card balance for that billing cycle would be approximately $14.79.
