Credit cards aren't free money

A credit card looks like magic — buy now, pay later. The 'pay later' part is where it gets ugly.

When you swipe a credit card, the bank pays the store and you owe the bank. If you pay the bank back in full each month, it's basically free. If you don't… they start charging you interest. A LOT of interest.

~22.5% APR

Average credit card interest

Federal Reserve G.19 (2026): the average APR on cards assessed interest is around 22–23%. If you owe $1,000 and only pay the minimum, it can take 5+ years to pay off — and you'll pay $600+ extra in interest.

The two rules that keep cards safe

  • ONLY buy what you'd pay cash for.
  • Pay the WHOLE balance every month — never just the minimum.
The minimum payment trap

The 'minimum due' is designed to keep you in debt as long as possible. Banks make money when you only pay the minimum.

Real life: meet Two friends, one card

Aiden and Eli each charge $500 on a 22% APR card. Aiden pays it in full — owes $0 in interest, builds his score. Eli pays the $25 minimum — three years later he's still paying it off and has spent $720 total.

Aiden: $500 · Eli: $720 over 3 years

Takeaway

Credit cards are tools — used right, they build credit and earn rewards. Used wrong, they're the most expensive borrowing in your wallet.

What happens if you only pay the minimum on a credit card balance?

For parents & teachers

Takeaway: Used like a debit card and paid in full, a credit card is a free credit-history builder.

Try together: Look at a real credit card statement (yours or a sample). Calculate what the 'minimum payment' would cost over 3 years.
