Balance Transfer Credit Cards: How They Work

A balance transfer moves debt from a high-APR card to a card offering 0% APR for an introductory period — typically 15 to 21 months. Used correctly, it can save thousands. Used wrong, it makes things worse.

The math

Example: $8,000 balance at 24% APR. Keeping it: $1,920/year in interest. Transferring to a 0% APR card for 18 months with a 3% fee: $240 fee, $0 interest. Net savings if paid off in 18 months: ~$2,640.

Eligibility

Most 0% offers require a credit score of 680+. The new card's credit limit determines how much you can transfer — sometimes less than your full balance. You can't transfer between cards from the same issuer.

The traps

• Deferred interest: Some "0% for 12 months" offers retroactively charge interest from day one if not paid off. Read the fine print — "0% intro APR" is safer than "no interest if paid in full."
• Post-promo APR: Jumps to 18–29% when the intro ends. Have a payoff plan for the full balance before applying.
• Running up the old card: A balance transfer doesn't fix the underlying spending. Many users end up with double the debt.
