What a balance transfer is and why people do it
A balance transfer means moving debt you owe on one credit card to a different credit card, usually one with a lower interest rate. The new card's issuer pays off your old balance, and you then owe that amount to them instead. People do this to reduce the interest they pay each month, especially if their current card charges a high rate or they are carrying a large balance.
The math is straightforward: if you owe $5,000 at 22% interest on one card and move it to a card charging 0% for the first 12 months, you stop paying interest during that period and can put more of each payment toward the actual debt. After the promotional period ends, interest kicks in at the card's regular rate, so the goal is usually to pay down the balance before that happens.
Balance transfers work best when you have a concrete plan to pay down what you owe before the promotional rate expires. Without that plan, you end up with the same debt at a higher rate once the offer ends.
Key Takeaways
- Balance transfer cards typically offer 0% interest for 6 to 21 months, but you pay a one-time fee (usually 3% to 5% of the amount transferred) upfront.
- You need to be approved for a new card before the transfer happens, which requires a credit check and takes a few days to a week.
- The transfer itself takes 5 to 14 business days after approval, during which time you still owe interest on your old card.
- Your old card account usually stays open after the transfer, which can affect your credit score and may tempt you to run up new debt.
- Balance transfers only make sense if you can pay down the balance during the promotional period, because the regular interest rate after that is often higher than what you started with.
How to find and compare balance transfer cards
Start by checking what interest rate and fees your current card charges, and what your credit score range is. Most balance transfer cards require a credit score of 670 or higher, though some accept lower scores. The better your score, the better the promotional offer you will see.
Look at three things on any card you consider: the length of the 0% promotional period (ranges from 6 to 21 months depending on the card), the balance transfer fee (usually 3% to 5% of the amount you move, with a minimum of $5 to $10), and the regular interest rate that kicks in after the promotion ends. A card with a longer 0% period but a 5% fee might still save you money compared to a card with a shorter period and a 3% fee — the math depends on how much you owe and how fast you can pay it down.
You can research cards through the card issuer's website, through comparison sites that show multiple cards side by side, or by calling the issuer directly to ask about current offers. Offers change frequently, so the rate or period you see online may not be what you are offered when you apply.
The approval and transfer timeline
Once you have chosen a card, you submit an application. The issuer runs a credit check (a hard inquiry, which temporarily lowers your credit score by a few points) and decides whether to approve you within a few minutes to a few days. You will receive a decision by email, phone, or mail depending on the issuer.
If approved, the issuer gives you a credit limit and asks you to provide the details of the balance you want to transfer: your old card number, the amount, and sometimes the old card issuer's name. You can request the transfer immediately or wait. The transfer itself takes 5 to 14 business days. During this time, you still owe interest on your old card, so continue making at least the minimum payment until the transfer shows up on your new card's statement.
Once the transfer posts, your old card balance drops to zero (or to whatever you did not transfer), and your new card shows the transferred amount. The promotional 0% period starts on the date the transfer posts, not the date you applied.
Fees and what they actually cost
The balance transfer fee is the most visible cost. If you transfer $5,000 and the fee is 3%, you pay $150 upfront — either added to your new balance or charged separately depending on the card. A 5% fee on the same amount is $250. This fee is not negotiable and applies to everyone, regardless of credit score.
Beyond the transfer fee, you may also pay an annual fee on the new card (some cards charge $0, others charge $95 to $450 per year). Factor this into your decision: if the card charges $95 per year and you plan to keep it open for two years, that is $190 in annual fees on top of the transfer fee.
The real cost of a balance transfer is whether you actually pay down the balance before the promotional period ends. If you transfer $5,000 at 3% fee ($150 total cost) and pay it off in 12 months during a 0% promotional period, your cost is $150. If you transfer the same amount, pay off only $2,000 during the 12 months, and then carry $3,000 at 18% interest for another year, your cost is $150 plus $540 in interest — much higher than staying on your original card might have been.
How the transfer affects your credit score
A balance transfer affects your credit in two ways. First, the hard inquiry from the credit check lowers your score by a few points for a few months. Second, opening a new card lowers your average account age (credit bureaus like older accounts) and uses up some of your available credit, both of which can temporarily lower your score.
However, if the transfer significantly lowers your credit utilization — the percentage of your available credit that you are using — your score may recover and even improve within a few months. For example, if you owed $5,000 on a card with a $6,000 limit (83% utilization) and transfer that $5,000 to a new card with a $10,000 limit, your utilization on the old card drops to 0% and on the new card is 50%, which is better for your score overall.
The key is not to run up new debt on your old card after the transfer. Many people transfer a balance, then use the now-empty old card to make new purchases, ending up with more total debt than they started with.
What happens to your old card after the transfer
Your old card account usually stays open after you transfer the balance, even if the balance is now zero. You have three options: keep it open and unused, keep it open and use it for small purchases you pay off each month, or close it.
Closing the card removes that available credit from your credit utilization calculation, which can lower your score slightly. Keeping it open preserves your available credit and your account history, both of which help your score. However, keeping an old card open means you have another account to monitor and another card that could be compromised if lost or stolen.
If you decide to close the old card, do so after the balance transfer has fully posted and you have confirmed the balance is zero. Call the card issuer's customer service line, confirm there are no remaining balances or pending transactions, and ask them to close the account. Request written confirmation of the closure.
When a balance transfer does not make sense
A balance transfer is not worth doing if you cannot pay down the balance during the promotional period. If you owe $10,000 and the 0% period is 12 months, you need to pay roughly $833 per month to clear it. If you cannot commit to that, the transfer fee and the eventual higher interest rate will cost you more than staying put.
A balance transfer also does not make sense if your current card's interest rate is already low (under 10%) or if you only owe a small amount (under $1,000). The fee eats up too much of the savings. Similarly, if your credit score is very low, you may not be approved for a card with a good promotional offer, making the transfer not worth the hard inquiry.
Finally, do not do a balance transfer if you are planning to apply for a mortgage, car loan, or other major credit in the next few months. The hard inquiry and new account will lower your score temporarily, which can affect the interest rate you are offered on that loan.
Frequently Asked Questions
Can I transfer a balance from one card to the same card issuer?
No. Most card issuers do not allow you to transfer a balance from one of their cards to another of their cards. You must transfer to a card from a different issuer. If you want to move a balance within the same company, you would need to close one card and open a new one, which is not the same as a balance transfer.
What if I am denied for the balance transfer card?
A denial usually means your credit score is below the card's minimum requirement or you have too much existing debt relative to your income. You can reapply after a few months if you have improved your score or paid down other debts. Each application triggers a hard inquiry, so space them out. Applying to multiple cards in a short time can lower your score further.
Can I transfer a balance from a store card or a loan?
Most balance transfer offers are limited to credit card debt, but some cards allow transfers from store cards, medical bills, or personal loans. Check the specific card's terms before applying. The process and timeline are the same, but the fee structure may differ.
What happens if I miss a payment during the promotional period?
Missing a payment usually ends the promotional 0% rate immediately, and the regular interest rate applies to your entire balance right away. You may also face a late fee and a mark on your credit report. Even one missed payment can wipe out all the savings from the balance transfer, so set up automatic payments or calendar reminders.
Can I do multiple balance transfers to different cards?
Yes, you can transfer balances to multiple cards if you are approved for them. Some people move different balances to different cards to maximize promotional periods. However, each application triggers a hard inquiry, and managing multiple cards with different due dates increases the risk of missing a payment.
