Is a balance transfer worth it?
Last updated November 9, 2026
A balance transfer moves debt from one credit card to another, usually to get a low or 0% introductory rate. Done well, it can save a lot of interest. Done carelessly, it can cost more than it saves.
How it works
A new card pays off your old card, and you now owe the new issuer. Many offers carry 0% interest for a set period, often 12 to 21 months. Most charge a transfer fee, commonly a few percent of the amount moved.
A worked example
You owe $6,000 on a card at 24% APR and pay $300 a month. The new card offers 0% for 18 months with a 3% fee.
| Plan | Time to pay off | Interest plus fee |
|---|---|---|
| Stay on the 24% card | 26 months | about $1,740 |
| Transfer, pay $300 a month | 21 months | about $210 ($180 fee plus about $30 interest) |
| Transfer, pay about $344 a month | 18 months | $180 (the fee only) |
The fee is $180 (3% of $6,000). With $300 a month, about $780 is left when the 0% period ends, and a few months at the regular rate cover it. Paying about $344 a month clears the balance inside the promotional window.
What to check before you transfer
- The fee. Add it to the balance. A 5% fee on $6,000 is $300.
- The promo length. Divide the new balance by the number of months to see the payment you need to finish in time.
- The rate afterward. It may be higher than your current card.
- Whether new purchases get the 0% rate. Often they do not.
- Late payments. Some offers end the promotional rate if you pay late.
- Approval and limit. You may not be approved, or the limit may be lower than your balance.
The main risk
The biggest risk is behavior. If the old card fills up again, you can end up with both balances. Consider keeping the old card unused while you pay down the new one.
Compare with your other options
A balance transfer is one tool. A consolidation loan or a lower rate from your current issuer may fit better. Use the planner to see how a lower rate changes your payoff date.
