Most people with multiple credit card balances make the same error: they split their extra cash evenly across all their cards, or they throw it at the card with the lowest balance because it "feels" like progress.

Neither approach is wrong exactly. But both waste money.

Here's why. If you're carrying three cards — one at 24.99% APR, one at 19.5%, and one at 0% promo — and you send an extra $200 split evenly across all three, you just sent $67 to a card charging you nothing. That $67 could have gone to the 24.99% card instead, where it would have saved you real interest every single month.

Over 12 months, that kind of misallocation can cost $500+ in interest you didn't need to pay.

The fix is simpler than people think:

1. Map every balance — card name, balance, APR, minimum, due date, and any promo expiration

2. Pay every minimum first — protect yourself from late fees

3. Send every extra dollar to the card with the highest APR

4. Before each payment, ask three questions: Is this the highest-APR card? Is the minimum already covered? Is a promo rate about to expire?

That's it. No spreadsheet wizardry. No debt consolidation loan. Just a clear order and a quick check before each payment.

The people who pay off debt fastest aren't the ones who pay the most — they're the ones who pay the right card first.
