The basic steps for transferring a balance

To move a balance from one credit card to another, you contact the card you want to transfer to (the receiving card), tell them the name of the card you're transferring from, and provide your account number on that old card. The receiving card's issuer then requests the balance from your old card's issuer, and the two banks handle the transfer between themselves. You don't move money yourself — the card companies do it.

The process usually takes 5 to 21 days, depending on the two banks involved. During that time, you'll still owe the old card if the transfer hasn't posted yet, so keep making payments on the original card until you see the balance drop to zero. Once the transfer completes, your debt moves to the new card and you start paying that one instead.

Most balance transfers come with a transfer fee — typically 3% to 5% of the amount you move. This fee is added to your new balance, so if you transfer $5,000 with a 3% fee, you'll owe $5,150 on the new card. Some cards waive the fee for transfers completed within the first 60 or 90 days of opening the account, so check your card's terms before you start.

Key Takeaways

  • You initiate a balance transfer by calling or logging into the card you want to transfer to, not the card you're transferring from.
  • A transfer fee of 3% to 5% is added to your new balance unless your card offers a promotional waiver for transfers made within a set window.
  • The transfer takes 5 to 21 days to post, and you should keep paying your old card during that time to avoid late fees.
  • Balance transfers only make financial sense if the new card's interest rate is lower than your current rate or if it offers a 0% promotional period.

When a balance transfer saves you money

A balance transfer is worth doing only if the new card charges you less interest than you're paying now. If your current card has a 22% interest rate and you move the balance to a card with a 0% promotional rate for 12 months, you stop paying interest for that year — that's real savings. But if you transfer to a card with a 20% rate, you've just paid a 3% to 5% fee to save 2% in interest, which doesn't make sense unless you plan to pay off the balance very quickly.

The math changes if the new card offers a 0% introductory period. These typically last 6 to 21 months, depending on the card. During that time, interest doesn't accrue on the transferred balance, so every dollar you pay goes toward the principal instead of interest. If you can pay off the balance before the promotional period ends, a transfer fee of $150 on a $5,000 balance is worth it — you'd pay far more than that in interest on a 22% card over the same months.

Calculate your break-even point: divide the transfer fee by the difference between your old card's interest rate and the new card's rate. If your fee is $150 and you're dropping from 22% to 0%, you break even after about 8 months of payments. If you can't pay off the balance in that time, the transfer may not help.

What happens after the promotional period ends

When a 0% promotional rate expires, the card's regular interest rate kicks in. You'll find that regular rate in your card agreement — it might be 18%, 24%, or higher, depending on your credit score and the card's terms. If you still carry a balance when the promotion ends, you'll suddenly start paying interest again, often at a rate higher than your original card.

This is why balance transfers work best as part of a payoff plan, not as a way to shuffle debt indefinitely. Before you transfer, calculate how much you need to pay each month to clear the balance before the promotional period ends. If you're transferring $8,000 and the 0% period lasts 12 months, you need to pay roughly $667 per month to finish before interest kicks in.

Documents and information you'll need

When you contact the receiving card to start a transfer, have the following ready: your account number on the card you're transferring from, the name of that card's issuer (Discover, Chase, Capital One, etc.), and the amount you want to transfer. Some cards let you do this online through your account dashboard; others require a phone call to their customer service line.

You'll also need to know your Social Security number and current address, as the receiving card will verify your identity before processing the transfer. If you're transferring from a card at a different bank, have that card in front of you so you can read the account number correctly — a typo can send the transfer to the wrong account or delay it by days.

Limits on how much you can transfer

You cannot transfer your entire credit limit. Most cards allow you to transfer up to 95% of your available credit limit, and some allow less. If your new card has a $10,000 limit, you might only be able to transfer $9,500. The remaining $500 stays available for new purchases.

Your available credit also matters. If you have a $10,000 limit but already owe $6,000 on the card, your available credit is $4,000, and that's the maximum you can transfer. Paying down the new card first creates more room for a transfer, but that defeats the purpose if you're trying to move debt away from a high-interest card.

What to do if the transfer is denied or delayed

A transfer can be denied if the receiving card's issuer suspects fraud, if you've recently missed payments, or if your credit score has dropped significantly. If your transfer is denied, the issuer will usually tell you why — check the letter or call their customer service line to ask. You can try again after addressing the issue (like making a late payment current), or you can look for a different card with less strict requirements.

If a transfer is taking longer than expected, contact the receiving card's customer service and ask for a status update. Transfers typically take 5 to 21 days, but if yours is approaching three weeks with no movement, the issuer may need additional information from you or from your old card's bank. Don't assume it's lost — follow up and get a specific date when you can expect the balance to post.

Avoiding common mistakes

The biggest mistake is transferring a balance and then running up the old card again. Once you move the debt, close or stop using the card you transferred from, or you'll end up owing money on both cards. If you need the old card for emergencies, keep it open but put it away — don't carry it or use it for new purchases.

Another common error is missing the deadline for a promotional 0% rate. If the promotion lasts 12 months, mark your calendar for month 11 and check your balance. If you still owe money, contact the card issuer and ask about options — some will extend the promotional period if you ask, though this is not may provide. Waiting until the rate has already switched means you're now paying interest retroactively on the entire balance.

Finally, don't transfer to a card with an even higher regular interest rate just because the promotional period is longer. A 0% rate for 18 months on a card with a 26% regular rate is worse than a 0% rate for 12 months on a card with an 18% regular rate, because you'll pay more interest after the promotion ends if you can't pay off the balance.

Frequently Asked Questions

Does a balance transfer hurt my credit score?

A balance transfer causes a small, temporary dip in your credit score because the receiving card issuer runs a hard inquiry and opens a new account. Your score typically recovers within a few months. The transfer itself doesn't hurt you — what matters is whether you pay on time and keep your credit utilization low on both cards during the transfer period.

Can I transfer a balance from a store card to a regular credit card?

Yes, most regular credit cards accept balance transfers from store cards, though the transfer fee still applies. Store cards often have higher interest rates, so moving the balance to a card with a 0% promotional period can save significant money. Call the receiving card's customer service to confirm they accept transfers from the specific store card you have.

What if I can't pay off the balance before the 0% period ends?

The regular interest rate will apply to any remaining balance once the promotional period expires. You can try to negotiate with the card issuer for an extension, though this is not may provide. Your other option is to transfer the remaining balance to another card with a 0% promotional period, though you'll pay another transfer fee.

Do I need to close my old card after transferring the balance?

You don't have to close it, but you should stop using it. Closing a card can hurt your credit score by reducing your total available credit. Instead, keep the card open with a zero balance and don't use it for new purchases. This preserves your credit history and available credit without tempting you to carry a balance on two cards.

How long does a balance transfer actually take?

Most transfers post within 5 to 21 days, depending on how quickly the two banks communicate. Some cards are faster — certain issuers complete transfers in 3 to 5 days. During the waiting period, continue paying your old card to avoid late fees. Once the transfer posts, your old card balance should drop to zero and your new card balance will reflect the transferred amount plus the transfer fee.
