How a balance transfer actually works
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 pay off your old card's balance, and you owe that amount to the new card instead. The entire transaction happens between the two card companies — you do not send money yourself.
The new card typically offers a promotional period, often 6 to 21 months, during which the interest rate is 0% or very low. After that period ends, a regular interest rate kicks in. The catch is that balance transfers usually cost 3% to 5% of the amount you move, charged upfront, and you must may have access to for the new card based on your credit score and income.
Balance transfers work best when you have a concrete plan to pay down the debt during the promotional period. If you straightforward move the balance and keep spending, you end up with more total debt and a higher bill when the promotional rate expires.
Key Takeaways
- The new card's issuer pays your old card directly, so you need your old card number and current balance before you start.
- Balance transfer fees run 3% to 5% of the amount transferred and are added to what you owe on the new card.
- You must be approved for the new card first, which requires a credit check and usually a credit score of 670 or higher.
- The promotional 0% rate period lasts anywhere from 6 to 21 months depending on the card, so calculate whether you can pay off the balance in that time.
Step 1: Choose a balance transfer card and check if you may have access to
Start by looking at cards that offer a 0% promotional rate on balance transfers. Compare the length of the promotional period, the regular interest rate that applies after, and the transfer fee. Cards marketed for balance transfers typically have longer promotional periods (12 to 21 months) than cards with general 0% offers.
Check the card issuer's website for the credit score range they typically approve. Most balance transfer cards require a credit score of 670 or higher, though some go lower. If your score is below 650, you may not be approved, and a hard inquiry will still appear on your credit report even if you are denied.
Read the terms carefully for any restrictions. Some cards limit the transfer to a percentage of your credit limit, or they may not allow transfers from cards issued by the same company.
Step 2: Gather your old card information and calculate the true cost
Pull out your current credit card statement and note the exact balance you want to transfer, the card number, and the issuer's name. You will need this when you explore.
Calculate what the transfer will actually cost you. If you are transferring $5,000 and the fee is 4%, you owe $200 upfront, making your new balance $5,200. Then figure out your monthly payment: if the promotional period is 12 months, you need to pay roughly $433 per month to clear the debt before the regular rate kicks in. If that is not realistic for your budget, the transfer may not help.
Also check whether your old card issuer charges a fee for paying off the balance early. Most do not, but it is worth confirming.
Step 3: explore for the new card
explore online through the card issuer's website or by phone. You will be asked for your name, address, income, employment status, and Social Security number. The issuer will run a hard inquiry on your credit report, which temporarily lowers your score by a few points.
You will usually get a decision within minutes to a few days. If approved, the issuer will tell you your credit limit and your promotional rate terms. Write down the exact end date of the 0% period — this is critical.
Do not close your old card yet. Wait until the balance transfer is complete and shows on your new card statement.
Step 4: Request the balance transfer from the new card issuer
Once your new card arrives or you have your account number, contact the issuer to request the balance transfer. You can usually do this online through your account, by phone, or by mail. Provide your old card number, the issuer's name, and the exact amount you want transferred.
Ask the issuer how long the transfer will take. Most transfers post within 7 to 14 days, though some take up to 21 days. During this time, your old card is still active and you can still charge to it — do not do this, as you will end up with more debt.
Request written confirmation of the transfer request, including the amount, the promotional rate period, and the transfer fee. Keep this for your records.
Step 5: Monitor the transfer and set up a payment plan
Check your new card account online a few days after you request the transfer to see if it has posted. You should also see the transfer fee added to your balance. Once the transfer appears, log into your old card account and confirm the balance has been paid to zero.
Set a calendar reminder for the last month of your promotional period. This is when you need to have the balance paid off, or you will owe the regular interest rate on whatever remains.
Set up automatic monthly payments from your bank account to the new card. Calculate the payment so you will pay off the full balance before the promotional period ends. For example, if you owe $5,200 and have 12 months, set up a $433 automatic payment each month. This removes the risk of forgetting a payment and triggering a penalty rate.
What happens if you cannot pay off the balance in time
If you still owe money when the promotional period ends, the regular interest rate applies to the remaining balance. This rate is usually 15% to 25%, depending on your creditworthiness and the card. You will owe interest on whatever is left.
If you are close to paying it off, you may be able to do another balance transfer to a different card with a new promotional period. However, each transfer costs 3% to 5%, so this strategy only works if the new promotional rate is long enough to justify the fee.
If you fall behind on payments during or after the promotional period, the card issuer may charge a penalty rate of 25% to 29.99%, which is the highest rate allowed by law. Missing a payment also damages your credit score.
Frequently Asked Questions
Can I transfer a balance from one card to another card from the same bank?
Most card issuers do not allow transfers between their own cards. Check the terms before you explore. If you are stuck with one issuer, you will need to explore for a card from a different bank.
What if my credit score drops after I explore but before the transfer completes?
The issuer approved you based on your credit at the time of process, so a small drop in the meantime will not affect the transfer. However, if you miss a payment or max out another card before the transfer posts, the issuer could cancel the approval or reduce your credit limit.
Do I have to use the new card for anything other than the balance transfer?
No. You can leave the card unused after the transfer. However, some issuers close accounts that show no activity for a long time, which could hurt your credit score. If you want to keep the account open, charge something small occasionally and pay it off in full.
What if I want to cancel the balance transfer after I request it?
Contact the card issuer when ready and ask to cancel the transfer request. If the transfer has not posted yet, they can usually stop it. Once it posts to your account, you cannot undo it, but you can pay the balance back to your old card if you change your mind.
Does a balance transfer hurt my credit score?
Yes, temporarily. The hard inquiry and the new account lower your score by 5 to 10 points. However, if you pay on time and keep your credit utilization low, your score will recover within a few months and may end up higher than before because you have less debt.
