How Is Interest Calculated on Credit Card Cash Advance

Credit card cash advances provide quick access to funds, but they come with high interest rates. Understanding how interest is calculated on cash advances helps you make informed financial decisions and avoid costly borrowing.

How Cash Advance Interest Works

When you take a cash advance on your credit card, you're essentially borrowing money from the card issuer. This transaction is treated differently from regular purchases, and the interest calculation follows specific rules:

Cash advances typically have higher interest rates than regular purchases because they're considered higher risk by lenders.

The interest on cash advances is calculated based on the card's annual percentage rate (APR) or annual percentage yield (APY), depending on the issuer's pricing structure. The key difference is that APY includes compounding interest, while APR does not.

Daily Interest Calculation

Most credit cards calculate cash advance interest daily. The formula typically used is:

Daily Interest = (Daily Balance × Daily Interest Rate) / 365

Where the daily interest rate is derived from the card's APR. For example, if your card has a 25% APR, the daily interest rate would be 25% ÷ 365 ≈ 0.0685% per day.

Difference Between APR and APY

Understanding the difference between these two terms is crucial when comparing cash advance options:

APR (Annual Percentage Rate) is the simple interest rate charged on the cash advance. It doesn't account for compounding.
APY (Annual Percentage Yield) is the effective annual rate that includes the effect of compounding interest.

For cash advances, APY is typically higher than APR because the interest compounds daily. The relationship between them can be expressed as:

APY = (1 + APR/365)^365 - 1

For example, a 25% APR would have an APY of approximately 28.9% when compounded daily.

How to Calculate Cash Advance Interest

To calculate the total interest on a cash advance, follow these steps:

Determine the cash advance amount
Identify the card's APR or APY
Calculate the daily interest rate (APR ÷ 365)
Determine the number of days the advance will be outstanding
Calculate the total interest using the formula:

Total Interest = Cash Advance Amount × (1 + Daily Interest Rate)^Number of Days - Cash Advance Amount

This calculation accounts for compounding interest, which means the interest grows with each passing day.

Example Calculation

Let's say you take a $500 cash advance with a credit card that has a 25% APR. Here's how the interest would accumulate over 30 days:

Day	Balance	Daily Interest	New Balance
0	$500.00	-	$500.00
1	$500.00	$0.34	$500.34
2	$500.34	$0.34	$500.68
3	$500.68	$0.34	$501.02
...	...	...	...
30	$500.00	$0.34	$516.72

After 30 days, the total interest would be $16.72, bringing the total amount owed to $516.72.

Key Takeaways

Cash advance interest is typically calculated daily and compounds over time
APR is the simple interest rate, while APY accounts for compounding
Cash advances often have higher interest rates than regular purchases
Interest grows significantly over time, making cash advances expensive
Always compare APRs and APYs when evaluating cash advance options
