Why Credit Card Debt Is So Expensive
Credit cards typically carry among the highest interest rates of any common consumer debt, often 20-30% APR, compared to single-digit rates for mortgages or auto loans. Because interest compounds daily on most cards, a balance left unpaid grows faster than borrowers often expect from the advertised annual rate alone.
Why Minimum Payments Barely Move the Balance
Card issuers typically set minimum payments at just 1-3% of the balance, an amount often barely above the monthly interest charge. Paying only the minimum on a high-APR balance can stretch payoff out for decades and multiply the total interest paid many times over the original balance — this is the single most common reason credit card debt becomes difficult to escape.
Payoff Strategies When Carrying Multiple Cards
Debt avalanche: Pay minimums on all cards, then put every extra dollar toward the highest-APR card first. This minimizes total interest paid and is the mathematically optimal approach.
Debt snowball: Pay off the smallest balance first regardless of rate, then roll that payment into the next-smallest. This pays slightly more interest overall but tends to build momentum through early wins, which research on behavioral finance suggests helps some people stick with the plan longer.
Balance Transfers as an Alternative
Some cards offer promotional 0% APR balance transfer periods (commonly 12-21 months), which can dramatically cut interest cost if the balance is paid off before the promotional period ends. Transfer fees (typically 3-5% of the transferred amount) need to be weighed against the interest saved to know if a transfer is actually worthwhile.
