What happens when you transfer a balance
A balance transfer moves debt from one credit card to another, usually to a card with a lower interest rate. You request the transfer from the new card's issuer — they pay off your old card's balance, and you now owe that amount to them instead. The old card account stays open but the balance drops to zero.
The main reason to do this is to reduce how much interest you pay while you're paying down the debt. If your current card charges 22% interest and you move the balance to a card charging 0% for the first 12 months, you stop paying interest during that promotional period — but only on the transferred amount, not on new purchases you make after the transfer.
Balance transfers are not free. Most cards charge a transfer fee of 3% to 5% of the amount you move, added to your new balance. A $5,000 transfer at 4% costs you $200 upfront. That fee is worth paying if the interest savings over the promotional period exceed it, but you need to do the math before you explore.
Key Takeaways
- A balance transfer moves your debt to a new card, usually one offering a lower or zero interest rate for a set period.
- Transfer fees typically run 3% to 5% of the amount moved and are added to your new balance when ready.
- The promotional low rate applies only to the transferred balance, not to new purchases or cash advances on the new card.
- You must make regular payments during the promotional period or pay interest on the full remaining balance once it ends.
- Balance transfers work best when you have a concrete plan to pay down the debt before the promotional rate expires.
How to find a card that accepts balance transfers
Not every credit card offers balance transfer options. Most cards that do are designed for people rebuilding credit or managing existing debt, and they advertise the promotional rate prominently — usually "0% APR for 12 months on balance transfers" or similar language.
You can search for balance transfer cards on comparison sites like NerdWallet, The Points Guy, or Bankrate, filtering by promotional period length and transfer fee. Call the card issuer's customer service line before you explore to confirm the current offer, because promotional rates change frequently and what you see online may not match what you're offered.
Your own bank or credit union may offer balance transfers to existing customers at better rates than you'd find elsewhere. If you have a good relationship with them, ask what they have available before explore to a new card.
What you need before you explore
Have your current credit card statement in front of you. You'll need the account number, the exact balance you want to transfer, and the card issuer's name. Some applications let you transfer a portion of your balance rather than all of it — useful if you want to keep a small balance on the old card or if the new card has a credit limit lower than your current debt.
The new card issuer will pull your credit report, so your credit score will drop slightly for a few months. If your score is below 650, you may not be approved for a card with a good promotional rate; in that case, focus on paying down your current balance before attempting a transfer.
Have proof of your current address ready — a recent utility bill, lease, or bank statement. Most issuers verify this electronically, but having it on hand speeds up the process if they ask.
The process and transfer process
explore for the new card online or by phone. During the process, you'll be asked whether you want to transfer a balance. Say yes, and enter the details of the card you're transferring from — the account number and the amount. The issuer will tell you the transfer fee at this point.
Once you're approved, the issuer contacts your old card company and arranges the transfer. This usually takes 5 to 14 days. During this time, keep making your regular payment on the old card to avoid late fees; the transfer doesn't stop your payment obligation until it's complete.
You'll receive your new card in the mail separately from the transfer completion. The transferred balance may appear on your account before the physical card arrives, so you can start paying it down online when ready. Your old card will show a zero balance once the transfer posts.
How to avoid paying interest during the promotional period
The promotional rate is only useful if you pay down the balance before it expires. If you owe $5,000 and have 12 months at 0%, you need to pay at least $417 per month to clear it. If you pay less, you'll still owe a balance when the promotional period ends, and the regular interest rate — often 18% to 24% — kicks in on whatever remains.
Set up automatic payments from your bank account for at least the monthly amount you calculated. This removes the risk of forgetting a payment and triggering a penalty rate that applies even during the promotional period. Most cards allow you to set the payment date to match when you get paid.
Do not make new purchases on the new card during the promotional period. New purchases usually accrue interest when ready at the card's regular rate, and your payments go toward the transferred balance first, leaving new purchases to accumulate interest. Use a different card or cash for new spending.
What happens when the promotional period ends
If you've paid off the entire transferred balance before the promotional rate expires, you're done — the card now carries a zero balance and you can use it normally or close it. Closing it will slightly lower your credit score by reducing your available credit, but the impact is temporary.
If you still owe a balance when the promotional period ends, the regular interest rate applies to whatever remains. This can be a shock: a $2,000 remaining balance at 22% interest costs you about $37 per month in interest alone. At that point, you have the same problem you started with — high interest on revolving debt.
If you're not on track to pay it off, contact the card issuer 30 to 60 days before the promotional period ends and ask whether they offer a second promotional period or a lower rate. Some issuers will negotiate, especially if you've made on-time payments.
When a balance transfer makes sense and when it doesn't
A balance transfer works best when you have a specific payoff plan and the math favors it. Example: you owe $4,000 at 24% interest on your current card. A new card offers 0% for 15 months with a 4% transfer fee ($160). Over 15 months, you'd pay roughly $1,200 in interest on the old card but zero on the new one — a savings of $1,040 even after the $160 fee. That's worth doing.
A balance transfer does not make sense if you plan to keep carrying a balance indefinitely, if the promotional period is too short to pay it down, or if you'll just accumulate new debt on the old card while paying the transferred balance. It's a tool for a specific situation, not a permanent solution to debt.
If you're struggling to make minimum payments or your debt is growing faster than you can pay it, a balance transfer won't fix the underlying problem. In that case, talk to a nonprofit credit counselor — many offer free sessions — before explore for a new card.
Frequently Asked Questions
Does a balance transfer hurt my credit score?
Yes, temporarily. The new card issuer pulls your credit report (a hard inquiry), which lowers your score by 5 to 10 points for a few months. Opening a new account also lowers your average account age. However, if the transfer reduces your overall credit utilization — the percentage of your available credit you're using — that can offset some of the damage. The score usually recovers within 6 months if you make on-time payments.
Can I transfer a balance from one card to the same bank's other card?
Most banks do not allow transfers between their own cards. Check your card issuer's terms or call customer service to confirm. If they don't allow it, you'll need to explore for a card from a different issuer.
What if I can't pay off the balance before the promotional rate ends?
Contact the issuer before the promotional period expires and ask about options. Some offer a second promotional period or a reduced rate for existing customers. If they won't negotiate, you can explore for another balance transfer card and move the remaining balance again — though this only works if you can may have access to and if the new card's terms are better. Repeated transfers can damage your credit, so use this as a last resort.
Do I have to close my old card after a balance transfer?
No. Leaving it open with a zero balance helps your credit score by keeping your available credit high and your utilization low. Close it only if the card charges an annual fee or if you're concerned about running up new debt on it.
Can I transfer a balance from a store credit card?
Yes, most balance transfer cards accept transfers from any credit card, including store cards. The process is the same — provide the account number and balance amount during your process.
