What a balance transfer is and how it works
A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You contact the new card issuer, give them your old card details, and they pay off that balance on your behalf. You then owe the new card issuer instead of the old one.
The main reason people do this is to save money on interest. If your current card charges 22% annual interest and you transfer to a card offering 0% for 12 months, you pay nothing in interest during that period — as long as you don't add new charges and you pay down the balance before the promotional rate ends.
Balance transfers are not the same as a cash advance or a personal loan. The new card issuer is paying your old creditor directly, so the money never touches your hands. This also means you cannot transfer a balance to a card from the same bank that issued your current card.
Key Takeaways
- Balance transfers move your debt to a new card, usually with a lower interest rate for a set period, but you pay a one-time fee of 3% to 5% of the amount transferred.
- You need an active credit card account with the new issuer before you can request a transfer, and the new card must be approved and in your hands first.
- The promotional interest rate lasts only as long as the card issuer states — typically 6 to 21 months — and the regular rate kicks in after that period ends.
- You must pay down the transferred balance before the promotional period ends, or you will owe interest on whatever remains at the card's standard rate.
- Balance transfers work best if you have a concrete plan to pay off the debt during the promotional window and you avoid charging new purchases to the new card.
Check your credit score and find cards that accept balance transfers
Most balance transfer cards require a credit score of 670 or higher, though some issuers accept scores as low as 600. You can check your own credit score free through your bank's online portal, through a service like Credit Karma or AnnualCreditReport.com, or by asking your current card issuer directly — many display your score in your account dashboard.
Once you know your score range, search for balance transfer cards that match it. Look at the promotional interest rate (how long it lasts), the balance transfer fee (usually 3% to 5% of the amount you move), and any annual fee. A card with a 0% rate for 18 months and a 3% transfer fee is often better than one with 0% for 12 months and no fee, because the longer window gives you more time to pay down the balance without interest charges.
Read the fine print on the card issuer's website. Some cards limit how much you can transfer — for example, you might only be able to move up to 95% of your new credit limit. Others charge a flat fee instead of a percentage, which matters if you are transferring a small balance.
Request the balance transfer from your new card issuer
Once your new card arrives and is activated, log into your online account or call the card issuer's customer service number. Tell them you want to request a balance transfer. They will ask for your old card number, the card issuer's name, and the amount you want to transfer.
You can usually transfer up to your new card's credit limit, minus any fees. If your new card has a $5,000 limit and the transfer fee is 3%, you can move up to about $4,850 in debt (the $150 fee comes out of your available credit). Some issuers let you request the transfer online through your account portal; others require a phone call.
The issuer will give you a confirmation number and an estimated timeline — usually 5 to 14 business days for the transfer to post. During this time, keep paying your old card's minimum payment to avoid late fees. Once the transfer completes, your old card balance will drop to zero (or near zero if you made new charges), and the amount will appear on your new card's statement.
Understand the promotional period and plan your payoff
The 0% interest rate (or reduced rate) lasts only as long as the card issuer promises. If your card offers 0% for 12 months, that clock starts the day the transfer posts to your account, not the day you requested it. After 12 months, the regular interest rate applies to any remaining balance.
Calculate how much you need to pay each month to clear the balance before the promotional period ends. If you transferred $3,000 and have 12 months at 0%, you need to pay at least $250 per month. Build in a small buffer — aim to pay it off a month or two early — so that if you miss a payment or make a smaller one, you still clear it before interest kicks in.
Write down the end date of the promotional period and set a phone reminder for one month before. If you cannot pay off the balance by then, you have time to look for another balance transfer card and move the remaining debt again, though each transfer costs another fee.
Avoid new charges and late payments on the new card
Do not use the new card for everyday purchases while you are paying down the transferred balance. New charges usually carry the card's regular interest rate when ready — they do not get the 0% promotional rate. This means you could be paying interest on new purchases while your transferred balance sits at 0%, which defeats the purpose of the transfer.
Set up automatic payments for at least the minimum amount due each month, or better yet, set up a fixed payment that will clear the balance by the end of the promotional period. Missing even one payment can trigger a penalty interest rate, which is usually much higher than the regular rate and can wipe out your savings.
Keep your old card open after the balance transfers, even though the balance is now zero. Closing it can hurt your credit score by reducing your available credit and shortening your credit history. Use it occasionally for a small charge and pay it off when ready, just to keep the account active.
Know what happens when the promotional period ends
If you have paid off the entire transferred balance before the promotional rate expires, you owe nothing more on that transfer. Any remaining credit limit on the card is yours to use, and you will not be charged interest on the transferred debt.
If you still owe a balance when the promotional period ends, the card issuer's regular interest rate applies to whatever remains. This rate varies by issuer and by your creditworthiness, but it is typically between 16% and 25%. You will start accruing interest on the remaining balance when ready, so the longer you wait to pay it off, the more you owe.
If you cannot pay off the balance in time, look for another balance transfer card with a new promotional period. You can transfer the remaining balance to that card and start the clock again. Each transfer costs another fee, so this strategy only works if the new card's promotional period is long enough to make up for the fee cost.
Balance transfers versus other debt payoff methods
A balance transfer is not the only way to lower your interest rate. A personal loan, a debt consolidation loan, or a home equity line of credit (if you own a home) can also move your debt to a lower rate. The trade-off is that these loans have fixed terms and fixed monthly payments, whereas a balance transfer card lets you pay as much as you want each month.
Balance transfers work best if you have a realistic plan to pay off the debt within the promotional window and if your credit score is high enough to get a card with a long 0% period. If your score is lower, the promotional period may be shorter, which makes the math tighter. If you cannot commit to a payoff plan, a personal loan with a fixed monthly payment might be easier to manage.
You can also use the debt avalanche or debt snowball method without a balance transfer — paying extra on your highest-interest card first, or your smallest balance first. These methods take longer but do not require a new credit process or a balance transfer fee.
Frequently Asked Questions
Does a balance transfer hurt my credit score?
Yes, but usually only temporarily. The new credit card process triggers a hard inquiry, which can lower your score by a few points. Opening a new account also lowers your average account age. However, as you pay down the transferred balance, your credit utilization drops, which helps your score recover. Most people see their score bounce back within a few months.
Can I transfer a balance from one card to the same bank's other card?
No. Most card issuers do not allow you to transfer a balance between their own cards. You must transfer to a card from a different bank. If you want to move debt within the same bank, you would need to use a personal loan or another method instead.
What happens if I miss a payment during the promotional period?
Missing a payment can trigger a penalty interest rate, which is usually much higher than the regular rate and may explore to your entire balance, not just the missed payment. It can also damage your credit score. Set up automatic payments to avoid this risk, even if the automatic amount is just the minimum due.
Can I do multiple balance transfers to the same card?
Some cards allow multiple transfers during the promotional period, but each transfer counts as a separate transaction and may have its own fee. Check your card's terms to see if this is an option. If you want to move debt from multiple old cards, it is often simpler to transfer all of it in one request rather than doing separate transfers.
What if I pay off the balance before the promotional period ends?
You owe nothing more on that transferred amount. You will not be charged interest, and you can use any remaining credit limit on the card for other purchases. The promotional period ends automatically, but since you have no balance left, it does not affect you.
