Interest Calculator Credit Card Cash Advance

Credit card cash advances can be convenient but often come with high interest rates. This calculator helps you understand the total cost of borrowing money through a cash advance, including daily interest charges and the total amount you'll need to repay.

How Credit Card Cash Advance Interest Works

When you take a cash advance from your credit card, you're essentially borrowing money against your available credit limit. The interest on cash advances is typically calculated on a daily basis, and the rate can be significantly higher than the rate you pay on purchases.

Key Differences from Purchases

Cash advances are treated differently from regular purchases on your credit card statement. The interest rate for cash advances is often:

Higher than the purchase APR (typically 5-10% higher)
Calculated daily rather than monthly
Not subject to the same grace period as purchases

How Interest is Calculated

The interest on a cash advance is calculated using the daily balance method. Here's how it works:

Your cash advance amount is posted to your account immediately
Daily interest is calculated based on the daily balance
Interest is added to your balance each day until the amount is paid in full
You'll receive a statement showing the total interest charged

Cash advances are often used for emergencies or large purchases, but they should be used carefully due to the high interest rates and potential impact on your credit score.

Formula and Assumptions

The total interest for a credit card cash advance can be calculated using the following formula:

Total Interest = (Daily Interest Rate × Advance Amount × Number of Days) / 365

Where:

Daily Interest Rate is the APR divided by 365
Advance Amount is the cash you withdrew
Number of Days is the time until full repayment

Assumptions

Interest is calculated daily on the outstanding balance
No grace period is applied to cash advances
The APR is the same for the entire period
No minimum payment requirements are considered

Worked Example

Let's calculate the interest for a $500 cash advance with a 24% APR, paid in full after 30 days.

Daily Interest Rate = 24% ÷ 365 ≈ 0.06575%

Total Interest = (0.06575% × $500 × 30) ÷ 365 ≈ $2.44

In this example, the total interest charged would be approximately $2.44. The total amount you would need to repay would be $502.44.

Comparison Table

Days Until Payment	Interest Charged	Total Repayment
15 days	$1.22	$501.22
30 days	$2.44	$502.44
60 days	$4.88	$504.88
