A balance transfer is when you move a debt you owe on one credit card over to a different credit card — usually one that charges a lower interest rate for a set period. The goal is simple: pay less in interest so more of your payment goes toward the actual balance instead of finance charges.
How a balance transfer works
When you open or already hold a card that offers balance transfers, you ask the new card to pay off some or all of a balance on another card. The new card now holds that debt, and the old card balance drops (often to zero).
Many cards advertise a promotional period during which transferred balances are charged a reduced or temporarily lower interest rate. After that promotional window ends, any remaining balance typically returns to the card’s regular interest rate. The exact rate and length of any promotion vary widely by card and by your approval terms.
The balance transfer fee
Most cards charge a one-time fee to move a balance over, commonly calculated as a percentage of the amount you transfer. That fee is added to your new balance, so it is worth comparing the fee against the interest you expect to save.
Because fee structures differ between issuers and even between offers from the same issuer, always confirm the exact percentage and any minimum dollar amount on your official card terms before transferring.
When a balance transfer makes sense
A balance transfer can help most when you have higher-interest debt and a realistic plan to pay it down during a lower-rate window. The math works in your favor when the interest you avoid is larger than the transfer fee.
It tends to work against you if you only make minimum payments, let the promotional period lapse with a large balance remaining, or keep adding new purchases to the old card. A transfer reorganizes debt; it does not erase it.
Things to check before you transfer
Look at the length of any promotional rate, the regular rate that applies afterward, the transfer fee, and whether new purchases are treated differently from the transferred balance. Also confirm whether there is a deadline to complete the transfer after opening the card.
Finally, you generally cannot transfer a balance between two cards from the same issuer, and approval amounts are not guaranteed. Treat any number you see in an ad as an example and verify your own terms.
Frequently asked questions
Does a balance transfer hurt my credit?
Applying for a new card can involve a credit inquiry, and opening an account changes your average account age and available credit. Paying down debt over time is generally viewed positively, but effects vary by individual. This is educational information, not a prediction about your specific score.
Can I transfer more than one balance?
Many cards let you transfer balances from multiple cards, up to your approved credit limit and any transfer caps the issuer sets. Confirm the limits on your card terms.
What happens after the promotional period ends?
Any balance still remaining typically begins accruing interest at the card’s standard rate. The best way to benefit is to pay the balance down before the promotion expires.
