What happens when you transfer a balance between cards
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, who pays off part or all of your old card's balance directly to that creditor. The debt then appears on your new card instead, and you owe the new issuer rather than the old one.
The main reason people transfer balances is to reduce interest charges during a promotional period. Many cards offer 0% annual percentage rate (APR) for a set number of months on transferred balances — commonly 6 to 21 months, depending on the card and the issuer. If you have high-interest debt on an existing card, moving it to a 0% card can save you hundreds of dollars in interest, but only if you pay down the balance before the promotional period ends.
Balance transfers are not free. Most cards charge a balance transfer fee of 3% to 5% of the amount you transfer, calculated upfront and added to your new balance. Some cards waive this fee for transfers completed within a certain window, usually the first 60 days after opening the account. You should factor this fee into your decision — on a $5,000 transfer with a 4% fee, you pay $200 when ready, so you need enough interest savings to make the move worthwhile.
Key Takeaways
- A balance transfer moves your debt from one card to another, typically to take advantage of a 0% promotional APR period that lasts between 6 and 21 months.
- Balance transfer fees range from 3% to 5% of the amount transferred and are added to your new card balance, though some cards waive the fee if you transfer within 60 days of opening the account.
- You must request the transfer from the new card's issuer, who contacts your old card company directly — you do not pay the old card yourself.
- After the promotional period ends, any remaining balance reverts to the card's regular APR, which is often higher than your original card's rate, so a repayment plan before that date is essential.
- Not all of your balance may transfer if the new card's credit limit is lower than the amount you owe, and you will still owe the remainder on your original card.
How to request a balance transfer
Start by opening a new credit card that offers a 0% balance transfer promotion. You can find these offers on the card issuer's website, on comparison sites, or in pre-approved offers you receive in the mail. Read the terms carefully: note the length of the 0% period, the balance transfer fee, and any restrictions (some cards limit transfers to balances opened within the last 60 days, or exclude transfers from the same issuer).
Once you are approved for the new card and receive it, contact the issuer to request the balance transfer. Most issuers let you do this online through your account, by phone, or by mail. You will need to provide the account number of the card you are transferring from, the name of that card's issuer, and the amount you want to transfer. The new card's issuer will then contact your old card company and arrange payment directly.
The transfer typically takes 5 to 14 business days to complete, though some issuers are faster. During this time, keep making at least minimum payments on your old card — the transfer does not happen when ready, and you remain responsible for that debt until it is paid off. Once the transfer posts, your old card's balance will drop by the transferred amount, and your new card's balance will increase by that amount plus the transfer fee.
Understanding promotional periods and what happens after
The 0% APR period applies only to the balance you transfer, not to new purchases you make on the card. If you use the new card for shopping during the promotional period, those purchases accrue interest at the card's regular APR from day one. To avoid confusion, many people stop using the new card for purchases and use a different card instead until the promotional period ends.
The length of the promotional period varies widely. Cards aimed at people with good credit often offer 12 to 21 months at 0%, while cards for fair credit typically offer 6 to 12 months. A longer promotional period gives you more time to pay down the balance without interest, but these cards may have higher regular APRs or annual fees. Calculate whether the interest savings justify any annual fee the card charges.
When the promotional period ends, any remaining balance on the transferred amount switches to the card's regular APR. This rate is often 15% to 25%, depending on your creditworthiness and the card's terms. If you have not paid off the balance by then, you will owe interest on whatever remains. This is why a repayment plan is critical: divide your transferred balance by the number of months in the promotional period to find the monthly payment you need to make to reach zero by the time the offer expires.
When a balance transfer makes financial sense
A balance transfer saves you money only if the interest you avoid exceeds the transfer fee and any annual fee. Here is how to do the math: multiply your current balance by your current APR and divide by 12 to find your monthly interest charge. Multiply that by the number of months in the promotional period to estimate total interest you would pay without transferring. Then subtract the balance transfer fee and any annual fee from that number. If the result is positive, the transfer is worth considering.
Balance transfers work best when you have a concrete plan to pay down the balance during the promotional period. If you cannot commit to a monthly payment schedule, the transfer may not help — you will straightforward move your debt to a new card and owe interest again once the promotion ends. Be honest about your ability to pay: if you are currently unable to pay more than the minimum on your existing card, a balance transfer alone will not fix that problem.
A balance transfer is less useful if your current card already has a low APR, if your balance is very small, or if you have poor credit and cannot may have access to for a card with a long 0% period. In these cases, the fee and effort may outweigh the benefit. It is also not a solution for ongoing overspending — if you are transferring a balance because you are using credit cards to cover expenses you cannot afford, the underlying problem remains.
What to do with your old card after the transfer
Once the balance transfer completes and your old card's balance is zero, you have three options: close the card, keep it open and unused, or keep using it for new purchases. Closing the card when ready has a small negative effect on your credit score because it reduces your total available credit and shortens your average account age. However, this effect is usually temporary and minor.
Keeping the card open with a zero balance can help your credit score over time, since it maintains your available credit and shows a long account history. The downside is an annual fee if the card charges one — check your card's terms to see whether you will owe a fee on an inactive account. If there is no annual fee, leaving it open costs nothing and may benefit your credit profile.
If you keep the old card, do not use it for new purchases during the promotional period on your transfer card. New purchases on the old card will accrue interest at its regular rate, and you may be tempted to carry a balance again. Once you have paid off the transferred balance on your new card, you can reassess whether to use either card going forward.
Common mistakes to avoid
The biggest mistake is underestimating how much you need to pay each month. If you transfer $10,000 at 0% for 12 months, you need to pay roughly $833 per month to reach zero by the time the promotion ends. Many people transfer a balance, feel relieved by the lower interest rate, and then pay only the minimum — which may be $200 or $300 per month. When the promotional period ends, they still owe $6,000 or $7,000, and suddenly face interest charges again.
Another common mistake is making new purchases on the transfer card during the promotional period. These purchases accrue interest when ready at the regular APR, and if you are only making one payment per month, that payment is typically applied to the 0% balance first and the purchase balance second. This means your purchases stay on the card longer and cost more in interest.
Some people also transfer a balance without checking whether they may have access to for the promotional rate. Card issuers sometimes advertise a 0% offer but explore it only to people with excellent credit scores. If your score is lower, you may be approved for the card but offered a shorter promotional period or a higher APR. Always read your approval letter carefully to confirm the actual terms you received.
Alternatives to balance transfers
If you do not may have access to for a balance transfer card or the promotional period is too short to make a difference, other options exist. A personal loan from a bank or credit union often carries a lower fixed APR than a credit card, and you know exactly how long you will pay and what your monthly payment will be. Personal loans also force you to commit to a repayment schedule, which can help if you struggle with discipline.
A debt consolidation loan works similarly — it combines multiple debts into one loan with a single monthly payment. This can simplify your finances and sometimes lower your overall interest rate, though the loan itself carries a fee and you may pay interest for a longer period than you would have on the original debts.
If your debt is very high or you are unable to pay, you might explore credit counseling through a nonprofit agency. These organizations do not lend money but help you create a budget and sometimes negotiate with creditors to lower your interest rate or set up a debt management plan. Be cautious of for-profit credit counseling companies, which often charge high fees and may not have your best interests in mind.
Frequently Asked Questions
Can I transfer a balance from one card to the same issuer's other card?
Most issuers do not allow transfers between their own cards. If you want to transfer a balance from a Chase card to another Chase card, for example, Chase will typically decline the request. You will need to open a card from a different issuer, such as American Express, Citi, or Capital One, to move the balance.
What happens if I cannot pay off the balance before the promotional period ends?
Any remaining balance will start accruing interest at the card's regular APR once the 0% period expires. You can continue paying the balance down after the promotion ends, but you will owe interest on whatever remains. Some people transfer the remaining balance to another 0% card to extend the interest-free period, though this incurs another transfer fee.
Does a balance transfer hurt my credit score?
A balance transfer typically causes a small, temporary dip in your credit score because the new card issuer performs a hard inquiry and opens a new account. However, moving debt from one card to another does not change your total debt, so your credit utilization ratio may improve if the new card has a higher credit limit. The score usually recovers within a few months.
Can I transfer a balance if I have bad credit?
You can try, but approval is less likely and the terms will be less favorable. Cards that accept applicants with lower credit scores may offer shorter promotional periods (6 months instead of 18) or charge higher balance transfer fees (5% instead of 3%). You may also be approved for a lower credit limit, which means you cannot transfer your entire balance.
Is there a limit to how much I can transfer?
Yes. The amount you can transfer is limited by your new card's credit limit, which the issuer sets based on your credit score, income, and credit history. If your balance is $8,000 but your new card's limit is $5,000, you can transfer only $5,000 and will still owe $3,000 on your original card. You can request a credit limit increase after you open the account, but the issuer is not required to grant it.
