How a balance transfer works

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 pay off your old card's balance, and you then owe that amount to the new card instead. The goal is to reduce how much interest you pay while you work down the debt.

The new card typically offers a promotional period — often 0% interest for 6 to 21 months, depending on the card and the issuer. After that period ends, the regular interest rate kicks in. Most cards charge a balance transfer fee upfront, usually 3% to 5% of the amount you move. That fee gets added to your new balance.

Balance transfers work best when you have a plan to pay down the debt during the promotional period, before interest resumes. If you carry the balance past the promotional window, you may end up paying more in interest than you would have on your original card.

Key Takeaways

  • A balance transfer fee of 3% to 5% is charged upfront and added to your new balance, so calculate whether the savings from a lower rate outweigh that cost.
  • The promotional 0% interest period typically lasts 6 to 21 months, after which the regular interest rate applies to any remaining balance.
  • You must request the transfer from the new card's issuer, who contacts your old card company to pay off the balance directly.
  • Balance transfers only save money if you pay down the debt during the promotional period before regular interest rates resume.
  • Your credit score may dip temporarily when you open a new card and when the transfer is reported, but usually recovers within a few months.

Steps to transfer a balance

First, find a card that offers a balance transfer with terms that fit your situation. Compare the length of the promotional period, the regular interest rate after it ends, and the transfer fee. You can check these details on the card issuer's website or by calling their customer service line.

Once you have chosen a card, open the account. You will need to provide your name, address, Social Security number, and income. The issuer will run a credit check and tell you whether you are approved and what your credit limit is. This usually takes a few minutes to a few hours.

After your account is open, contact the new card issuer to request the balance transfer. You can usually do this online, by phone, or through their mobile app. You will need to provide the account number of the card you want to transfer from, the amount you want to move, and the old card issuer's name. The new issuer will then contact your old card company and arrange payment.

The transfer typically takes 5 to 14 business days to complete. During this time, keep making minimum payments on your old card to avoid late fees. Once the transfer posts to your new card, your old balance will be paid off and you will owe the amount on the new card instead.

Balance transfer fees and how they affect your savings

Most cards charge a balance transfer fee of 3% to 5% of the amount transferred. Some cards offer 0% transfer fees for a limited time, usually the first 60 days after opening the account. A few cards have no transfer fee at all, though these are less common and may have shorter promotional periods or higher regular interest rates.

To decide whether a transfer makes financial sense, calculate the fee cost against the interest you would pay on your current card. For example, if you transfer $5,000 with a 4% fee, you pay $200 upfront. If your current card charges 20% interest and you plan to pay off the balance in 12 months, you would pay roughly $1,000 in interest without the transfer. The $200 fee is worth it. But if you only plan to pay $1,500 of the balance during the promotional period and then carry the rest at the new card's regular rate, the math changes.

Write down the promotional period length, the regular interest rate after it ends, and the transfer fee. Then estimate how much you can pay each month and whether you will reach zero before the promotional period ends. This calculation tells you whether the transfer will actually save you money.

What happens when the promotional period ends

When the 0% promotional period expires, any remaining balance on the new card begins accruing interest at the card's regular rate. That rate varies by card and by your creditworthiness, but typically 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 when ready.

Some people transfer the remaining balance to another card with a new promotional period, a strategy called balance transfer stacking. This can work if you find another card with a long promotional period and low or no transfer fee. However, each new card process and transfer affects your credit score, and opening multiple cards in a short time can signal financial stress to lenders.

The safest approach is to pay down as much as possible during the promotional period so that little or no balance remains when it ends. If you know you cannot pay off the full amount, a balance transfer may not be the right move.

How a balance transfer affects your credit score

Opening a new credit card triggers a hard inquiry on your credit report, which typically lowers your score by a few points. This dip is temporary and usually recovers within a few months. The new account also lowers your average account age, which can reduce your score slightly.

When you transfer a balance, your credit utilization on the new card increases when ready. Credit utilization is the percentage of your available credit that you are using. If you transfer $5,000 to a card with a $10,000 limit, your utilization on that card is 50%. High utilization can lower your score, though this effect also tends to reverse as you pay down the balance.

Your old card's balance drops to zero, which improves your overall utilization across all your cards. This positive effect often offsets some of the damage from the new account and higher utilization on the new card. Most people see their score recover to its previous level or higher within 3 to 6 months, assuming they make on-time payments on both cards.

When a balance transfer does not make sense

A balance transfer is not worth doing if you cannot pay down the debt during the promotional period. If you are only able to make minimum payments and the balance will still be substantial when the promotional rate expires, you will end up paying interest at the new card's regular rate anyway. In that case, the upfront transfer fee is just an extra cost.

Balance transfers also do not help if your current card already has a low interest rate or if you have poor credit. Cards with the longest promotional periods and lowest transfer fees typically require good to excellent credit. If you are denied for the cards with the best terms, the savings may not be large enough to justify the fee and the credit score impact.

If you are struggling to pay your debt and do not have a realistic plan to pay it down, a balance transfer is a temporary fix that can make your situation worse. In that case, talking to a nonprofit credit counselor about a debt management plan or other options may be more helpful.

Frequently Asked Questions

Can I transfer a balance to a card from the same bank?

Most banks do not allow you to transfer a balance between their own cards. You typically must transfer to a card from a different issuer. Check the card's terms or call the issuer to confirm whether they accept transfers from other banks.

What if my balance transfer is denied?

The issuer may deny a transfer if your credit limit is too low to cover the amount you want to move, or if they determine you are too high-risk. You can request a higher credit limit after your account is open, or you can transfer a smaller amount. If you are denied by multiple issuers, your credit may not be strong enough for the best balance transfer cards right now.

Do I have to pay off the entire balance during the promotional period?

No, but any balance remaining when the promotional period ends will start accruing interest at the regular rate. The promotional period is your window to pay down the debt interest-free. The longer the period, the more time you have to pay it off without interest charges.

Can I make new purchases on a balance transfer card?

Yes, but new purchases typically have a different interest rate than the transferred balance and do not get the promotional 0% rate. New purchases usually start accruing interest when ready at the card's regular rate. To avoid confusion, many people use a balance transfer card only for the transferred balance and make new purchases on a different card.

How long does a balance transfer take to show up on my new card?

Most transfers take 5 to 14 business days, though some issuers complete them faster. You can track the status by logging into your new card's account online or by calling customer service. Until the transfer completes, keep making minimum payments on your old card to avoid late fees.
