Use This Tool to See the Real Cost of Credit Card Debt

The Hidden Cost of Your Credit Card Purchase

That $100 jacket. The $500 flight. The $1,200 laptop. You probably didn’t think twice when you swiped your card — especially if it felt like a necessary purchase. But if you're like most Americans, you might carry that balance for a few months… and that $100 isn’t really $100 anymore.

Credit cards are convenient, but they come with a cost when you don’t pay them off right away. The average credit card interest rate is over 20% — and that means purchases grow more expensive every month you carry a balance. What seemed affordable at checkout can quietly add up to much more.

Use This Calculator to Find Out What You’re Really Paying

Try it for yourself. Just enter the purchase amount, your credit card’s interest rate (APR), and how many months you'll carry the balance. We’ll show you what that item actually cost in the end.

Why This Matters

When you pay in full before interest hits, your credit card works like a free 30-day loan. But once you carry a balance, interest compounds — meaning you’re not just paying for what you bought, you’re paying interest on the interest. Over time, this adds up fast.

The True Cost of Your Credit Card Purchase

Use this calculator to see how much a credit card purchase really costs if you don’t pay it off right away. Just enter your purchase amount, interest rate, and how many months you'll carry the balance.

Purchase Amount ($):

Interest Rate (% APR):

Months Unpaid:

Total Cost: $143.86

Interest Paid: $43.86

That $100.00 purchase really costs you $143.86 if you don’t pay it off for 22 months at 20% APR.

That’s money that could’ve gone to your emergency fund, your savings, or your next goal. Instead, it quietly disappears into interest payments.
