What Is a Balance Transfer and How Does It Work?

Quick answer: A balance transfer moves debt from one credit card to another, usually to take advantage of a 0% introductory APR for a set period (often 12–21 months). You'll typically pay a balance transfer fee of 3%–5% of the amount moved. It saves money only if you pay off the balance before the intro period ends.
How a Balance Transfer Works
- You're approved for a card with a 0% intro APR on balance transfers.
- You ask the new issuer to pay off a balance on another card (from a different bank).
- The new card charges a transfer fee and adds the debt to your new balance.
- You pay down the debt interest-free until the promo ends; then the regular APR applies.
Cost Example
| Keep on old card (25% APR) | Transfer to 0% for 18 months (4% fee) | |
|---|---|---|
| Balance | $3,000 | $3,000 + $120 fee |
| Monthly payment | $180 | $174 |
| Interest paid over 18 months | About $600 | $0 |
| Total cost | About $3,600 | $3,120 |
How to Do a Balance Transfer in 5 Steps
- Check your credit; the best offers need good credit.
- Compare intro length, transfer fee and regular APR.
- Apply and request the transfer (you'll need the old card's account number).
- Keep paying the old card until the transfer shows as complete.
- Divide the balance by the promo months and pay that amount each month.
Watch Out For
- You can't transfer between cards from the same bank (for example, Chase to Chase).
- New purchases may not get the 0% rate.
- A late payment can cancel the promo rate.
Balance Transfer With Bad Credit?
Most 0% offers require good credit, and secured cards rarely allow transfers. If your credit is fair or poor, consider a credit union personal loan or a debt management plan from a nonprofit credit counselor instead.
