How to Calculate Accrued Interest on A Credit Card

Accrued interest is a financial term that refers to the interest that has been earned but not yet paid on a credit card or other debt. Understanding how to calculate accrued interest helps you manage your finances more effectively and avoid unexpected charges.

What is Accrued Interest?

Accrued interest is the interest that has been calculated but not yet paid on a credit card or other debt. It represents the portion of interest that has been earned during a billing period but hasn't been added to the principal balance yet.

For example, if you have a credit card with a balance of $1,000 and an APR of 18%, the interest accrues daily. At the end of the billing cycle, the accrued interest is added to your statement balance.

Key Point

Accrued interest is different from interest charged. Accrued interest is calculated but not yet added to your balance, while interest charged is the amount that has been added to your balance.

How to Calculate Accrued Interest

Calculating accrued interest involves determining the interest earned on a debt over a specific period. The formula for calculating accrued interest is:

Accrued Interest Formula

Accrued Interest = (Principal × Daily Interest Rate × Number of Days) / 365

Where:

Principal = The amount of money borrowed or outstanding
Daily Interest Rate = Annual Percentage Rate (APR) divided by 365
Number of Days = The number of days in the billing period

Here's a step-by-step guide to calculating accrued interest:

Determine the principal balance on your credit card.
Find the Annual Percentage Rate (APR) for your credit card.
Calculate the daily interest rate by dividing the APR by 365.
Determine the number of days in the billing period.
Multiply the principal by the daily interest rate and the number of days.
Divide the result by 365 to get the accrued interest.

Example Calculation

Let's walk through an example to illustrate how to calculate accrued interest.

Suppose you have a credit card with a balance of $1,500 and an APR of 18%. You want to calculate the accrued interest for a 30-day billing period.

Principal = $1,500
APR = 18%
Daily Interest Rate = 18% ÷ 365 ≈ 0.049315%
Number of Days = 30
Accrued Interest = ($1,500 × 0.00049315 × 30) ÷ 365 ≈ $1.10

In this example, the accrued interest for the 30-day period is approximately $1.10.

Note

The actual amount of interest charged may vary slightly due to rounding and the specific calculation method used by the credit card issuer.

When is Accrued Interest Reported?

Accrued interest is typically reported on your credit card statement. The exact timing can vary depending on the credit card issuer and the billing cycle. Generally, accrued interest is added to your statement balance at the end of the billing period.

For example, if your billing cycle runs from the 1st to the 28th of each month, the accrued interest for that period will be added to your balance on the 28th.

It's important to review your credit card statements regularly to track accrued interest and ensure you understand the charges on your account.
