What happens when you transfer a balance
A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You request the transfer from the new card's issuer — they contact your old card company, pay off part or all of what you owe, and that debt now appears on your new card instead. The goal is to pay less interest while you work down what you owe.
The new card typically charges you an upfront fee, usually 3 to 5 percent of the amount transferred. So if you move $5,000, you might pay $150 to $250 as a one-time cost. In return, the new card often offers a period — sometimes 6 to 21 months — where interest does not accrue on that transferred balance. After that period ends, the regular interest rate kicks in.
Balance transfers work best when you have a concrete plan to pay down the debt during the interest-free window. If you straightforward move the balance and keep spending, you end up owing more across two cards.
Key Takeaways
- Balance transfers move your debt to a new card, usually one with a lower interest rate or an interest-free introductory period.
- You pay an upfront fee of 3 to 5 percent of the transferred amount, added to your new card balance.
- The new card issuer contacts your old card company directly — you do not need to call both yourself.
- Interest-free periods typically last 6 to 21 months, after which the regular rate applies to any remaining balance.
- You must stop using the old card or pay it down separately, because the transfer does not close the account.
Before you request a transfer
Check your credit score first. Most cards offering favorable balance transfer terms require a score of 670 or higher. You can view your score free through your bank's website, through a service like Credit Karma or AnnualCreditReport.com, or by asking your current card issuer directly — many display it in your online account.
Look at the cards you are considering and compare three numbers: the transfer fee (usually shown as a percentage), the length of the interest-free period, and the regular interest rate that applies after. A card with a 0 percent introductory rate for 18 months and a 4 percent fee is often better than one with 0 percent for 12 months and a 3 percent fee, because you have more time to pay without interest.
Calculate whether you can realistically pay off the transferred balance during the interest-free window. If you owe $3,000 and have 12 months interest-free, you need to pay $250 per month. If that is not realistic, a longer introductory period matters more than a lower fee.
How to request the transfer
Once you have chosen a new card, explore for it through the card issuer's website or by phone. During the process, you will see a field asking whether you want to transfer a balance from another card. This is where you enter your old card number, the issuer's name, and the amount you want to transfer.
You do not need to contact your old card company. The new card issuer handles that part — they will request the payoff amount, send the payment directly to your old issuer, and the transfer typically posts within 7 to 21 days. You can track the status in your new card's online account.
Some issuers let you request a balance transfer after you receive the card, through their website or by calling customer service. This option is useful if you want to wait for a promotional offer or if you were not approved for a transfer at the time of process.
What to do with your old card
The balance transfer does not close your old card. The account stays open with a zero balance (or near-zero if the transfer did not cover everything). You have three choices: keep it open and unused, keep it open and use it for small purchases you pay off monthly, or contact the issuer and ask them to close it.
Closing the card can lower your credit score slightly, because it reduces your total available credit and shortens your average account age. Keeping it open costs nothing if there is no annual fee. Many people keep old cards open for this reason, even if they do not use them.
If you do keep the card open and use it, pay the full balance each month. Any new purchases on that card will accrue interest at the regular rate — they are not covered by the balance transfer terms. The interest-free period applies only to the transferred balance.
Timing and what to expect
The transfer usually posts 7 to 21 days after you request it, though some issuers are faster. During this window, you still owe your old card company. Keep making your regular minimum payment on the old card until the transfer completes and you see the balance drop to zero (or close to it).
Once the transfer posts, your new card statement will show the transferred balance plus the transfer fee. For example, a $5,000 transfer with a 4 percent fee appears as a $5,200 balance on your new card. That $5,200 is what you need to pay down during the interest-free period.
Set up automatic payments or calendar reminders to stay on track. Many people set a monthly target — dividing the total by the number of interest-free months — and pay that amount automatically on the same day each month. This removes the temptation to skip a payment or let the balance sit.
Common mistakes to avoid
Do not assume the entire card has an interest-free rate. The 0 percent period covers only the transferred balance. Any new purchases you make on the new card accrue interest at the regular rate when ready, even during the promotional period. Some cards offer a separate 0 percent period for new purchases, but you have to check the terms.
Do not miss a payment. If you miss even one payment during the interest-free period, many issuers cancel the promotional rate and charge you the regular interest rate on the entire transferred balance, retroactively. This can happen even if you are only a few days late. Set up automatic payments to avoid this.
Do not transfer more than you can pay off. If you move $10,000 but can only pay $300 per month, you will not finish during the interest-free window. The remaining balance will then accrue interest at the regular rate, which defeats the purpose of the transfer.
When a balance transfer does not make sense
If your current card already has a low interest rate — under 10 percent — the fee and hassle may not be worth it. Calculate the total interest you would pay over the next year on your current card, then compare it to the transfer fee plus any interest after the promotional period ends.
If you cannot stop using credit while you pay down the transferred balance, a transfer will not help. You will straightforward accumulate new debt on top of the transferred amount. In this case, talking to a credit counselor about a debt management plan may be more useful.
If your credit score is below 650, you are unlikely to be approved for a card with favorable transfer terms. Focus on paying down your current balance first, then revisit a transfer once your score improves.
Frequently Asked Questions
Does a balance transfer hurt my credit score?
A hard inquiry and a new account will lower your score slightly — usually 5 to 10 points — but this is temporary. Your score typically recovers within a few months as you make on-time payments. The long-term benefit of paying less interest often outweighs the short-term dip.
Can I transfer a balance from one card to the same card?
No. You cannot transfer a balance from a card to itself. You must transfer to a different card from a different issuer. Some people open a new card with the same issuer and transfer between them, but this is rare and usually not worth the fee.
What happens if I do not pay off the balance before the interest-free period ends?
Any remaining balance starts accruing interest at the card's regular rate. This rate is usually 15 to 25 percent, depending on your creditworthiness and the card. You will owe interest on the unpaid portion going forward, so it is important to have a payment plan before you transfer.
Can I transfer a balance if I am behind on payments?
Most issuers will not approve a balance transfer if you are currently late on any credit account. You need to bring your accounts current first. Once you have made on-time payments for a few months, you become a stronger candidate for approval.
How many balance transfers can I do?
There is no legal limit, but each transfer costs a fee and triggers a hard inquiry. Doing multiple transfers in a short time can lower your credit score and make you look risky to lenders. Most people do one transfer and focus on paying it down, rather than moving balances repeatedly.
