The basic steps for transferring a balance

A balance transfer moves debt from one credit card to another, usually one with a lower interest rate or a promotional period where you pay no interest at all. The process itself is straightforward: you open a new card, tell the issuer how much of your old balance to move over, and they pay off that amount on your original card. The debt then sits on the new card under whatever terms that issuer offers.

The new card's issuer handles the mechanics. You do not pay the old card issuer directly; instead, the new issuer sends a payment to your old card on your behalf. This typically takes 5 to 21 days to complete, depending on the card companies involved. During that window, you may see the balance on both cards — the old one temporarily and the new one as it processes.

You will owe a balance transfer fee, usually 3 to 5 percent of the amount you move. Some cards waive this fee for transfers completed within the first 60 or 120 days of opening the account. The fee is added to your new card balance, so factor it into your math before you decide whether the transfer makes financial sense.

Key Takeaways

  • The new card issuer pays your old balance directly to your previous card company, so you do not handle the payment yourself.
  • Balance transfer fees range from 3 to 5 percent of the amount moved, though some cards offer a waived fee for transfers made early in your account life.
  • The transfer takes 5 to 21 days to post, and you may see the balance appear on both cards temporarily during that time.
  • A promotional 0 percent interest rate typically lasts 6 to 21 months, after which a standard purchase or cash advance rate kicks in.
  • You must continue making minimum payments on your old card until the transfer completes, or you risk late fees and credit damage.

What to do before you apply for the new card

Check your current credit report and score. Most balance transfer cards require a credit score of 670 or higher, and the best promotional rates go to people with scores above 740. You can pull your credit report free once per year at annualcreditreport.com, which is the only federally authorized site for free reports. Your credit score itself is not free from that site, but many banks and credit card issuers show your score for free if you are already a customer.

Add up the exact balance you want to move. Look at your current card statement and note the total you owe. Decide whether you want to transfer all of it or only part of it. Some people transfer the full balance; others move only the portion with the highest interest rate and leave smaller balances on cards with lower rates. Write down the account number of the card you are transferring from — you will need it when you apply.

Calculate whether the math works. Multiply the balance by the transfer fee percentage (usually 3 to 5 percent) and add that to your balance. Then look at the promotional interest rate period on the new card. If the promotional period is 12 months and you have $5,000 to move, you need to pay roughly $417 per month to clear it before interest kicks in. If that is not realistic for your budget, the transfer may not save you money.

Choosing which card to transfer to

The most important number is the length of the promotional 0 percent period. Cards vary widely: some offer 0 percent for 6 months, others for 18 or 21 months. The longer the period, the more time you have to pay down the balance before interest charges resume. A longer promotional window is usually worth a higher balance transfer fee, because you save more on interest.

Check what the regular interest rate will be after the promotional period ends. Most cards show this as a range — for example, 18 percent to 25 percent depending on your creditworthiness. This matters because if you do not pay off the full balance during the promotional period, you will owe interest on whatever remains. Some cards also charge interest on new purchases immediately, even during the promotional period, so read the terms carefully.

Look at whether the card charges an annual fee. Many balance transfer cards have no annual fee, but some premium cards do. If the annual fee is $95 and your promotional period is 12 months, that cost is built into your decision. A card with a $0 annual fee and a slightly higher balance transfer fee is often the better choice.

How to complete the transfer

Apply for the new card through the issuer's website or by phone. During the application, you will be asked whether you want to do a balance transfer. Say yes, and the application will ask you for the account number of the card you are transferring from and the amount you want to move. Enter the exact balance or the amount you calculated earlier. Do not guess — if you enter too low a number, you will have to call and request a second transfer later, which may trigger a second fee.

Once you are approved, the issuer will send you the new card and a welcome packet with your account details. Do not wait for the physical card to arrive if you want to start the transfer immediately. Most issuers let you initiate a transfer online or by phone as soon as your account is open, even before the card reaches your mailbox. Log into your new account online or call the number on your approval letter.

Request the balance transfer through your new card's website or customer service line. You will need the account number of your old card, the amount to transfer, and the old card issuer's name. The new issuer will then send a payment to your old card company. You will receive a confirmation number — save this. It lets you track the transfer's progress and proves you requested it if there are any delays.

What happens while the transfer is processing

Keep making minimum payments on your old card until the transfer completes. The balance transfer does not happen instantly, and your old card issuer will still charge interest and late fees if you miss a payment. Many people assume the transfer is done once they request it and stop paying the old card, which damages their credit and costs them money. Treat the old card as active until you see the balance drop to zero.

Watch for the balance to appear on your new card. Within 5 to 21 days, you should see the transferred amount show up on your new card statement. At the same time, the balance on your old card should drop by that amount. If 21 days pass and the transfer has not posted, call your new card issuer and reference your confirmation number. Delays are rare, but they happen, and you want to catch them before you accidentally miss a payment.

Do not close your old card once the transfer completes. Closing it can hurt your credit score by reducing your available credit and shortening your credit history. Instead, leave it open with a zero balance. You can use it occasionally for small purchases and pay it off in full each month, which keeps the account active and helps your credit.

Avoiding common mistakes during a balance transfer

Do not make new purchases on your new card during the promotional period unless you understand the terms. Many balance transfer cards charge the regular purchase interest rate on new charges immediately, even if your transferred balance is at 0 percent. This means a new purchase could cost you interest from day one. Read your card's terms to see whether new purchases are covered by the promotional rate or charged at the standard rate.

Do not miss a payment on your new card. If you are late by even one day, the card issuer can end your promotional rate and charge you the regular interest rate on your entire balance, including the transferred amount. This is called a "penalty rate" and can jump to 25 percent or higher. Set up automatic minimum payments if you are worried about forgetting, and aim to pay more than the minimum so you actually reduce the balance.

Do not transfer more than you can realistically pay off. The promotional period is not infinite. If you transfer $10,000 and the promotional period is 12 months, you need to pay roughly $833 per month to clear it. If your budget does not support that, you will owe interest on the remaining balance. Calculate your monthly payment target before you apply, and make sure it fits your income.

When a balance transfer does not make sense

If your current card already has a low interest rate — say, under 10 percent — a balance transfer may not save you money once you factor in the transfer fee. A 4 percent fee on a $5,000 balance costs $200. If your current card charges 8 percent interest and you pay off the balance in one year, you would owe roughly $200 in interest anyway. The transfer fee washes out the savings, so you are better off staying put.

If you have poor credit and can only get approved for a card with a short promotional period — say, 6 months — and a high transfer fee, the math may not work. A 5 percent fee plus a 6-month window leaves little time to pay down a large balance. In this case, focusing on paying down your current card without transferring might be faster and cheaper.

If you are planning to apply for a mortgage, car loan, or other major credit in the next few months, a balance transfer can temporarily lower your credit score. The new account and the hard inquiry both affect your score. If you are close to a credit milestone that affects your loan terms, it might be worth waiting to transfer until after you have closed on the loan.

Frequently Asked Questions

Can I transfer a balance from one card to the same issuer?

Most issuers do not allow you to transfer a balance between their own cards. You must open a card from a different issuer. A few issuers make exceptions for customers moving balances between product lines, but this is uncommon. Call the issuer before you apply if you want to transfer within the same company.

What if my balance transfer is denied?

The issuer may deny a transfer if your credit score is too low, your income is too high relative to your debt, or you have recent late payments. If you are denied, wait a few months, pay down other debts, and bring any late payments current before you apply again. You can also ask the issuer why you were denied — they are required to tell you.

Can I transfer a balance from a store card or gas card?

Yes, as long as it is a credit card with a balance. You cannot transfer a balance from a charge card that requires you to pay the full balance each month, or from a line of credit that is not a credit card. The issuer will tell you during the application whether your card type is may be able to access.

Does a balance transfer hurt my credit score?

A balance transfer causes a small, temporary dip in your credit score because of the hard inquiry and the new account. The dip usually recovers within a few months. However, if you close your old card or miss a payment on your new card, the damage is much worse and lasts longer. The transfer itself is not harmful if you manage the new card responsibly.

What happens if I do not pay off the balance before the promotional period ends?

Any remaining balance will start accruing interest at the card's regular rate, which is typically 18 to 25 percent. You will owe interest on that balance going forward until you pay it off. This is why calculating your monthly payment target before you transfer is important — it helps you avoid this situation.
