The basic mechanics of moving your 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, and the new issuer pays off part or all of your old balance. You then owe that amount to the new card instead of the old one.
The process typically takes 5 to 14 business days. During that time, you still owe your original card company—do not stop paying them until the transfer shows as complete on your account. Once the transfer posts, your old card balance drops and your new card balance rises by the transfer amount.
Most balance transfers come with a promotional interest rate, usually 0% APR for a set period (commonly 6 to 21 months, depending on the card and the issuer). After that period ends, the regular APR kicks in. If you have not paid off the transferred balance by then, interest accrues on whatever remains.
Key Takeaways
- The new card issuer pays your old card company directly, so the transfer does not require you to move money yourself.
- Balance transfers typically charge a one-time fee of 3% to 5% of the amount transferred, added to your new balance immediately.
- The promotional 0% period applies only to the transferred balance, not to new purchases you make on the new card.
- You must pay down the transferred balance before the promotional period ends, or you will owe the regular APR on whatever is left.
- Your credit score may dip temporarily because the transfer counts as a new account inquiry and increases your overall credit utilization.
The balance transfer fee and how it affects your payoff math
Nearly every balance transfer charges a transfer fee, typically 3% to 5% of the amount you move. If you transfer $5,000, expect to pay $150 to $250 as a one-time fee. This fee is added to your new card balance immediately—you do not pay it separately.
The fee matters because it increases the total amount you need to pay off. If you transfer $5,000 at 4% fee, you now owe $5,200 on the new card. Your promotional 0% period only covers interest, not the fee itself. The fee is part of your principal balance from day one.
Some cards marketed to people with excellent credit offer 0% transfer fees, but these are rare and usually come with shorter promotional periods or higher regular APRs. Compare the fee cost against the interest you would pay on your old card over the promotional period to decide whether the transfer makes financial sense.
What happens to your old card after the transfer
Your old card account stays open unless you close it. The balance drops to zero (or near zero if the transfer did not cover everything), but the account itself remains active. You can still use that card for new purchases if you want, though most people leave it alone during the payoff period.
Closing the old card immediately after a transfer can hurt your credit score because it reduces your total available credit and shortens your average account age. If you want to close it, wait until after you have paid off the new card's balance and your credit has recovered from the transfer inquiry.
If your old card had an annual fee, check whether it will charge you again. Some cards waive the fee for the first year or do not charge it if the balance is zero, but others will bill you even with a $0 balance. Contact the old card issuer to confirm before deciding whether to keep the account open.
The promotional period and what happens when it ends
The 0% APR period is a fixed window—typically 6, 12, 18, or 21 months depending on the card. This period applies only to the balance you transferred, not to new purchases. If you make new purchases on the card during the promotional period, those purchases usually accrue interest at the regular APR immediately.
Mark the end date of the promotional period on your calendar. On the day after it expires, any remaining balance on the transferred amount will start accruing interest at the card's regular APR. If you owe $2,000 when the period ends and the APR is 18%, you will owe roughly $30 in interest that first month alone.
Some cards offer a separate 0% period for new purchases, but you have to read the fine print carefully. Most do not. Assume that only the transferred balance gets the promotional rate unless the card explicitly states otherwise.
How the transfer affects your credit score
A balance transfer typically causes a small, temporary dip in your credit score—usually 5 to 10 points. This happens for two reasons: the new card issuer runs a hard inquiry on your credit report, and opening a new account lowers your average account age.
More significantly, the transfer increases your credit utilization ratio on the new card. If you transfer $5,000 to a card with a $10,000 limit, you are using 50% of that card's available credit. High utilization hurts your score. However, if your old card now has a $0 balance, your overall utilization across all cards may actually improve, which can offset some of the damage.
The score recovery is usually quick—within 3 to 6 months if you make on-time payments and do not open other new accounts. The bigger risk is if you run up the old card again after transferring its balance. That would increase your total debt and utilization, which would hurt your score more than the transfer itself.
When a balance transfer makes sense and when it does not
A balance transfer makes sense if you have high-interest debt (typically 15% APR or higher) and can realistically pay it off during the promotional period. The math is simple: if you owe $5,000 at 20% APR, you will pay roughly $1,000 in interest over one year. A transfer to 0% for 12 months with a 4% fee costs $200 upfront—a net savings of $800.
A transfer does not make sense if you cannot pay off the balance before the promotional period ends, or if you will rack up new debt on the old card while paying off the transferred balance. It also does not make sense if your current interest rate is already low (under 10%) or if you have poor credit and cannot may have access to for a card with a meaningful promotional period.
Be honest about your spending habits. If you have transferred balances before and ended up with debt on both the old and new cards, a transfer is a temporary fix, not a solution. The real work is cutting expenses or increasing income so you can actually pay down the principal.
Steps to request a balance transfer
First, choose a new card and get approved for it. You cannot request a balance transfer before you have an active account. Once approved, log into your new card's online account or call the customer service number on the back of the card.
Look for a "balance transfer" or "transfer balance" option in the account menu, or ask the representative directly. You will need to provide the name of your old card issuer, your old account number, and the amount you want to transfer. Some cards let you transfer from multiple old cards in one request.
The issuer will tell you the transfer fee and confirm the promotional period before processing. Review these details carefully—once you authorize the transfer, the fee is locked in. The transfer typically posts within 5 to 14 business days. Check both your old and new card accounts to confirm the transfer completed.
Frequently Asked Questions
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 open a new card with a different issuer (or occasionally a different product from the same issuer, but this is rare). The new card must be approved and active before you can request the transfer.
What if I cannot pay off the balance before the 0% period ends?
The remaining balance will start accruing interest at the regular APR. You can request another balance transfer to a different card with a new promotional period, but each transfer charges a fee and affects your credit. This approach works once or twice but becomes expensive and damaging if repeated.
Do I have to use the new card for anything else?
No. You can use it only for the transferred balance and leave it otherwise untouched. However, making small purchases and paying them off during the promotional period can help your credit utilization and shows the issuer you are using the account responsibly.
What if my old card company refuses the transfer?
This is extremely rare. Card issuers routinely process balance transfers from competitors. If there is a problem, the new card issuer will contact you with details. The most common issue is a mismatch in account information—make sure you provide the exact account number and cardholder name from your old card.
Can I transfer a balance from a store card or a loan?
Most balance transfer offers apply only to credit card debt. Some issuers allow transfers from store cards, but very few allow transfers from personal loans, auto loans, or medical debt. Check the specific card's terms before applying if you have non-credit-card debt you want to move.
