What a balance transfer is and how it works
A balance transfer moves debt from one credit card to another, usually to a card with a lower interest rate. You request the transfer through the new card's issuer, who pays off your old card's balance directly. You then owe the new card issuer instead of the old one.
The main reason to transfer is to reduce interest charges. Many balance transfer cards offer a 0% introductory rate for 6 to 21 months, depending on the card. After that period ends, the regular purchase or cash advance rate kicks in. You pay a one-time balance transfer fee—typically 3% to 5% of the amount transferred—when you move the balance.
Balance transfers work best if you can pay down the debt during the 0% period. If you carry the balance past the promotional rate, you may end up paying more in interest than you would have on your original card, especially if the new card's regular rate is higher.
Key Takeaways
- Balance transfers move your debt to a new card, usually one offering a 0% introductory rate for several months.
- You pay a one-time fee of 3% to 5% of the transferred amount when the balance moves.
- The new card issuer pays your old card directly, so you do not send money between cards yourself.
- You must request the transfer through the new card's issuer, not your old card, and have the new card open before you start.
- Balance transfers only work if you pay down the debt during the 0% period—after it ends, interest rates can be higher than your original card.
Step-by-step process for requesting a balance transfer
First, open the new credit card before you request the transfer. You cannot transfer a balance to a card that does not yet exist. Once your new card arrives and is activated, log into your online account or call the card issuer's customer service number on the back of your card.
Tell them you want to request a balance transfer. They will ask for the name of your old card issuer, your old account number, and the amount you want to transfer. Have your old card in front of you so you can provide the account number quickly. You can transfer part of your balance or all of it, but the amount cannot exceed your new card's credit limit.
The issuer will confirm the balance transfer fee (usually shown as a percentage) and the 0% promotional period length. Ask them to put this in writing or take a screenshot of the confirmation screen. The transfer itself typically takes 5 to 14 business days. During this time, keep paying your old card's minimum payment to avoid late fees.
Once the transfer posts to your new card, you will see the balance appear in your account. Your old card balance will drop to zero or near zero (depending on any new charges or fees). You can now focus on paying down the new card during the 0% period.
Understanding balance transfer fees and interest rates
The balance transfer fee is a one-time charge applied when the balance moves. If you transfer $5,000 with a 4% fee, you pay $200 upfront. This fee is usually added to your new card balance, so you owe $5,200 total. Some cards charge a flat fee instead of a percentage, but this is less common.
The 0% introductory rate applies only to the transferred balance, not to new purchases you make on the card. Any new charges accrue interest at the card's regular purchase rate when ready. To avoid confusion, do not use the new card for purchases during the promotional period—use a different card or pay in cash.
After the 0% period ends, the remaining balance converts to the card's standard interest rate. This rate varies by card and your creditworthiness, but it often ranges from 15% to 25%. If you still owe $3,000 when the promotional period ends, you will start paying interest on that $3,000 at the higher rate.
When a balance transfer makes financial sense
A balance transfer saves money only if the interest you avoid during the 0% period exceeds the balance transfer fee. If your current card charges 20% interest and you transfer $5,000 with a 4% fee, you pay $200 upfront but save roughly $1,000 in interest over 12 months—a net gain of $800.
The math changes if you cannot pay down the balance before the promotional rate ends. If you transfer $5,000, pay $1,000 during the 0% period, and still owe $4,200 when it expires, you will then pay interest on $4,200 at the new card's regular rate. Calculate how much you can realistically pay each month and whether you will clear the balance in time.
Balance transfers also make sense if your credit score has improved since you opened your original card. A higher score may may have access to you for a card with a longer 0% period or a lower regular interest rate, making the transfer more valuable. Check your credit score before explore for a new card so you know what rates you are likely to receive.
What to do with your old card after the transfer
Do not close your old card when ready after the balance transfers. Closing a card reduces your available credit and can lower your credit score. Instead, keep the account open with a $0 balance. You can set up a small recurring charge (like a streaming service) and pay it off monthly to keep the account active.
If you are concerned about overspending, ask the card issuer to lower your credit limit or remove the card from your wallet. You can still keep the account open without using it. After 6 to 12 months of inactivity, some issuers close accounts automatically, but this is less common than it once was.
Watch your old card's statements for a few months to confirm the balance is truly zero and no unexpected charges appear. Once you are certain the transfer is complete and the account is settled, you can decide whether to keep or close it based on your overall credit strategy.
Balance transfer vs. other debt payoff strategies
A balance transfer is not the only way to reduce credit card interest. A personal loan from a bank or credit union often carries a lower fixed interest rate and a set repayment timeline, which can force you to pay faster. However, personal loans require a credit check and take time to fund, whereas balance transfers are faster if you already have the new card open.
A debt consolidation loan combines multiple debts into one payment, which simplifies your finances but does not necessarily lower your interest rate. A 0% purchase card is different from a balance transfer card—it offers 0% on new purchases, not transferred balances, so it does not help with existing debt.
If you cannot may have access to for a balance transfer card due to a lower credit score, a personal loan or credit counseling service may be better options. If you have multiple cards with high balances, you might transfer the highest-rate card to a 0% card and pay minimums on the others while focusing extra payments on the transferred balance.
Common mistakes to avoid when transferring a balance
The most common mistake is making new purchases on the new card during the 0% period. Those purchases accrue interest when ready at the regular rate, which defeats the purpose of the transfer. Use a different card or cash for purchases until you have paid off the transferred balance.
Another mistake is missing a payment on the new card. Even one late payment can end the 0% promotional rate early and trigger a penalty interest rate, sometimes as high as 29.99%. Set up automatic minimum payments or calendar reminders to avoid this.
A third mistake is transferring to a card with a higher regular interest rate than your current card, then failing to pay off the balance during the 0% period. Always compare the regular rates before explore. If the new card's standard rate is 24% and your current card is 18%, the transfer only makes sense if you can pay off the balance before the promotional period ends.
Finally, do not explore for multiple balance transfer cards at once. Each process triggers a hard inquiry on your credit report, which can lower your score temporarily. Space out applications by at least a few months if you need multiple transfers.
Frequently Asked Questions
Can I transfer a balance from one card to the same card issuer?
Most issuers do not allow you to transfer a balance between their own cards. You must transfer to a card from a different issuer. If you want to move a balance within the same company, contact their customer service to ask about your specific situation, but expect the answer to be no.
What credit score do I need to get a balance transfer card?
Most balance transfer cards require a credit score of 670 or higher, though some accept scores as low as 600. Cards with longer 0% periods and lower fees typically require higher scores. Check the card issuer's website or call to ask about their minimum score before you formally request a card.
How long does a balance transfer take?
Most transfers post within 5 to 14 business days. Some issuers complete transfers in 3 to 5 days. During the transfer period, continue paying your old card's minimum to avoid late fees. Once the balance appears on your new card, you can stop paying the old card (unless there are remaining charges).
Can I transfer a balance if I am behind on payments?
You can request a transfer, but most issuers will deny it if your account is 30 or more days past due. Bring your account current first, then request the transfer. If you are in hardship, contact your current card issuer about a hardship program before explore for a new card.
What happens if I do not pay off the balance before the 0% period ends?
The remaining balance converts to the card's regular interest rate, and you begin accruing interest on that amount. If you owe $2,000 when the promotional period ends and the regular rate is 20%, you will pay roughly $33 per month in interest alone. Pay as much as possible before the period ends to minimize this.
