What a balance transfer is and how it works
A balance transfer moves debt you owe on one credit card to a different card, usually one with a lower interest rate. You do not pay off the first card yourself. Instead, the new card's issuer pays your old balance directly to your previous card issuer, and you then owe that amount to the new card company.
The process typically takes 5 to 14 business days. During that time, you should keep paying your original card's minimum payment to avoid late fees, even though the balance is being transferred. Once the transfer completes, the old card's balance drops to zero (or near zero if new charges posted after you initiated the transfer), and the new card shows the transferred amount as your balance.
Balance transfers are most useful when you are paying high interest on existing debt and can move it to a card offering a lower rate or a promotional period with no interest. The math only works if the new card's rate or offer is genuinely better than what you are currently paying.
Key Takeaways
- A balance transfer moves your debt from one card to another; the new card issuer pays your old issuer directly, and you owe the new card company instead.
- Most balance transfers take 5 to 14 business days to complete, and you should continue paying your original card during this time to avoid late fees.
- Balance transfer fees typically range from 3 to 5 percent of the amount transferred, charged upfront and added to your new balance.
- Promotional 0% interest periods usually last 6 to 21 months depending on the card and your creditworthiness, but the regular interest rate applies once the promotion ends.
- You need an active account with the new card issuer before you can request a transfer; some issuers let you open and transfer on the same day, while others require you to wait.
How to request a balance transfer from your new card issuer
Contact the card issuer you want to transfer the balance to—the new card company, not your old one. You can usually request a transfer through their website, mobile app, or by calling their customer service number. The issuer will ask for the account number of the card you are transferring from, the amount you want to move, and confirmation that you authorize the transfer.
Some issuers process balance transfer requests immediately; others require you to wait a set number of days after opening the account. Check your card's terms or call before you apply if timing matters. A few issuers let you request a transfer during the application process itself, so the transfer begins as soon as your account opens.
You do not contact your old card issuer to approve the transfer. The new issuer handles the entire process with your previous card company. However, you should log into your old account periodically during the transfer window to confirm the balance is dropping and no new interest is accruing on the amount being moved.
Balance transfer fees and how they are charged
Most card issuers charge a balance transfer fee of 3 to 5 percent of the amount you transfer. Some cards charge a flat fee instead (for example, $5 or $10), but percentage-based fees are far more common. A few cards marketed to people with excellent credit offer 0% balance transfer fees, though these are rare and usually come with other trade-offs like higher regular interest rates or annual fees.
The fee is charged upfront and added to your new card balance immediately. If you transfer $5,000 at a 3% fee, you owe $5,150 on the new card from day one. This amount is separate from interest; the fee is a one-time charge, while interest accrues on your balance going forward (unless you are in a promotional 0% period).
The fee is charged whether the transfer succeeds or fails. If the new issuer cannot complete the transfer for any reason—for example, because your old account was closed—you may still be charged. Read the card's terms to understand the issuer's policy on failed transfers before you request one.
Promotional 0% interest periods and when they end
Many cards offer a promotional period during which no interest accrues on your transferred balance. These periods typically last 6 to 21 months, depending on the card and your credit profile. The issuer determines your specific promotional length based on your creditworthiness at the time you open the account.
The promotional period begins on the date the transfer posts to your account, not the date you request it. If your transfer takes 10 days to complete, your 0% period starts 10 days after you initiated the request. The end date is fixed; it does not extend if you make late payments or miss a payment deadline.
Once the promotional period ends, the card's regular interest rate applies to any remaining balance. This rate is stated in your card agreement and may be different from the rate you saw in the offer. If you do not pay off the transferred balance before the promotion expires, interest will accrue on whatever amount remains at the regular rate, which can be 15% to 25% or higher depending on the card and your creditworthiness at that time.
What to do with your old card after the transfer
You have three options: keep the card open with a zero balance, keep it open and use it for new purchases, or close it. Each choice affects your credit differently.
Keeping the card open with a zero balance preserves your available credit and the card's history on your credit report, both of which can help your credit score. However, if the card has an annual fee, you will continue paying it even though you are not using the card. Check your card agreement to see if a fee applies.
Closing the card removes it from your active accounts and may lower your credit score slightly because it reduces your total available credit and removes an account from your history. The impact is usually small if you have other cards open, but it is worth considering if this is your oldest card or your only card with a high credit limit.
If you close the card, do so after the balance transfer completes and the zero balance is confirmed. Closing an account while a transfer is in progress can sometimes cause the transfer to fail or reverse. Contact the issuer to confirm the transfer is complete before you request closure.
Timing: when to request a transfer and how long it takes
Request a balance transfer as soon as your new card account is open and active, assuming the issuer allows transfers immediately. The sooner you transfer, the sooner you stop paying interest on that debt at your old card's rate.
The transfer itself typically takes 5 to 14 business days. Weekends and holidays do not count. If you request a transfer on a Friday, the clock starts Monday. Some issuers are faster; a few take up to 21 days. Your new card issuer will tell you the expected timeline when you request the transfer.
During the transfer window, your old card's balance remains active and interest continues to accrue on it. This is why you should keep making minimum payments to your old card—you are still responsible for it until the transfer completes. Once the transfer posts, the old balance drops and interest stops accruing on that amount.
When a balance transfer makes financial sense
A balance transfer saves you money only if the new card's interest rate or promotional offer is better than what you are currently paying, and only if you pay off the balance before the promotional period ends.
For example: you owe $3,000 on a card charging 22% interest. A new card offers 0% for 12 months with a 3% transfer fee. The fee costs $90, bringing your new balance to $3,090. Over 12 months with no interest, you pay $3,090 total. On your old card, that same $3,000 would cost roughly $3,660 in interest alone over 12 months. The transfer saves you about $570, minus the $90 fee, for a net savings of $480.
The math breaks down if you cannot pay off the balance before the promotional period ends. If you still owe $2,000 when the 0% period expires and the new card's regular rate is 20%, you will then pay interest on that remaining balance at the new rate. Plan your transfer only if you have a realistic path to paying off the balance during the promotional window.
Frequently Asked Questions
Can I transfer a balance to a card from the same issuer?
Most issuers do not allow you to transfer a balance from one of their cards to another of their cards. Some do, but the terms are usually less favorable than transferring to a different issuer. Check with your current card issuer before assuming a transfer is possible; if they do allow it, ask whether the promotional rate applies to internal transfers.
What happens if I miss a payment during the promotional period?
Missing a payment can end your promotional 0% period immediately, even if you are only a few days late. Once the promotion ends, the regular interest rate applies to your entire balance. Some issuers will reinstate the promotion if you call and explain the missed payment, but this is not may provide. Set up automatic minimum payments to avoid this risk.
Can I transfer a balance if I have bad credit?
You can transfer a balance only if a card issuer approves you for a new account first. Cards offering balance transfer promotions typically require good to excellent credit (usually a score of 670 or higher). If your credit is lower, you may still be approved for a card, but it may not offer a promotional rate or may offer a shorter promotional period.
Does a balance transfer hurt my credit score?
A balance transfer involves a hard inquiry and a new account, both of which can lower your score slightly in the short term. However, moving debt to a lower-rate card and paying it down usually improves your score over time because it lowers your overall credit utilization. The temporary dip is typically worth the long-term benefit if you use the transfer to pay down debt.
What if the transfer fails or does not go through?
If a transfer fails, the new issuer will usually contact you to explain why—often because your old account was closed, the account number was incorrect, or the old issuer rejected the request. You may still be charged the balance transfer fee even if the transfer fails. Contact the new issuer immediately to request a reversal of the fee and to troubleshoot why the transfer did not complete.
