Credit Card Debt Trap

Revolving balances turn convenience into a treadmill.

Start this lessonWhat is the credit card debt trap

The revolving mechanic

Unpaid balances accrue interest; new charges add to the pile. Without a plan, you pay interest on interest-class balances—often at high APR tiers.

Why minimums fail

Minimums often cover little principal—sometimes barely above the monthly interest. See the timeline with a payoff calculator; the years can shock you.

Breaking the cycle

  • Stop adding new charges you can’t pay in full.
  • Negotiate hardship or transfer options carefully—fees matter.
  • Use avalanche or snowball strategies—consistency beats perfection.

Should I invest while carrying card debt?

Usually pay off high-APR debt first—the guaranteed “return” equals the interest rate you avoid.
