Moving a balance means transferring debt from one credit card to another, usually to a card with a lower interest rate or a promotional period with no interest charges

A balance transfer works like this: you open a new card or use an existing one, request the transfer, and the new card's issuer pays off part or all of the balance on your old card. You then owe the new card issuer instead of the old one. The main reason people do this is to reduce how much interest they pay while they work down the debt.

The catch is that balance transfer cards charge a fee — typically 3 to 5 percent of the amount you move — and the low or zero interest rate lasts only for a set period, usually 6 to 21 months. After that period ends, a regular interest rate kicks in. This means a balance transfer only saves you money if you pay down the debt faster than you would have on your original card, or if the promotional rate is low enough to offset the fee.

Key Takeaways

  • Balance transfer fees run 3 to 5 percent of the amount moved, charged upfront or added to your new balance.
  • The interest-free period typically lasts 6 to 21 months, after which a regular purchase or balance transfer rate applies.
  • You need good credit (usually 670 or higher) to be approved for a card with a competitive promotional rate.
  • The math only works if you pay down the transferred balance before the promotional period ends or if the fee is smaller than the interest you would have paid on the old card.
  • Some cards let you transfer from multiple old cards at once, but each transfer counts toward your credit limit on the new card.

When a balance transfer makes financial sense

A balance transfer saves money only under specific conditions. First, you must have a plan to pay down the debt during the promotional period. If you transfer a $5,000 balance to a card with a 12-month zero-interest offer and a 3 percent fee, you pay $150 upfront and need to pay at least $417 per month to clear it before interest kicks in. If you cannot commit to that pace, the transfer may not help.

Second, compare the fee plus the promotional rate against what you would pay on your current card. If your old card charges 22 percent interest and you carry a $5,000 balance for one year, you pay roughly $1,100 in interest. A balance transfer with a $150 fee and zero interest for 12 months costs $150 total — a clear win. But if you can only pay $200 per month, you will still owe $2,600 when the promotional period ends, and then interest accrues on that remaining balance at the new card's regular rate.

Third, check whether you can avoid new charges on the new card during the promotional period. Some cards offer zero interest on transfers but charge regular interest on new purchases. Others extend the zero-rate offer to both. If you plan to keep using the card, the second type is safer.

Credit score requirements and approval odds

Balance transfer cards with the best promotional rates typically require a credit score of 670 or higher, and many issuers prefer 700 or above. If your score is lower, you may still be approved for a balance transfer card, but the promotional rate will be shorter or the regular rate higher. Some cards offer 0 percent for 6 months instead of 18, or charge 15 percent after the offer ends instead of 12 percent.

Your approval odds also depend on your credit utilization — how much of your available credit you are currently using — and your payment history. If you have missed payments or carry balances on multiple cards, issuers see you as higher risk. A hard inquiry will temporarily lower your score by a few points, so explore for multiple cards in a short window can hurt your approval chances on later applications.

Before you explore, check your credit report for errors at annualcreditreport.com, which is free and does not hurt your score. If your score is below 650, you may want to wait a few months and pay down existing balances to improve it before explore for a balance transfer card.

How to request and complete a balance transfer

Once you are approved for a new card, you can request the balance transfer in several ways: through the card issuer's website or mobile app, by calling the customer service number on the back of your new card, or sometimes during the process process itself. You will need the account number and balance of the card you want to transfer from, and the issuer's mailing address.

The issuer will then send a payment directly to your old card's issuer, usually within 5 to 7 business days. Some cards allow you to transfer from multiple old cards at once, but the total transferred cannot exceed your credit limit on the new card. For example, if your new card has a $10,000 limit and you transfer $8,000, you have $2,000 left to use for new purchases.

After the transfer posts, stop using the old card if possible. Leaving it open does not hurt your credit, and closing it can actually lower your score by reducing your available credit. Just make sure you do not rack up new debt on it while you are paying down the transferred balance on the new card.

Fees and what they really cost

The balance transfer fee is the biggest hidden cost. A 3 percent fee on a $5,000 transfer is $150. A 5 percent fee on the same amount is $250. This fee is usually charged upfront and added to your balance on the new card, meaning you owe it even if you pay off the transfer when ready.

Some cards advertise "0 percent balance transfer fee" for transfers made within a certain window — often the first 60 days after opening the account. If you may have access to for this offer and can transfer quickly, you save the fee entirely. However, these offers are rare and usually come with shorter promotional interest periods (6 months instead of 18) or higher regular rates after the offer ends.

Beyond the transfer fee, watch for annual fees on the new card. Some balance transfer cards charge $95 or more per year. If the promotional period is only 6 months, the annual fee might outweigh your savings. Read the card's terms and conditions — the document called the Schumer Box, which shows fees and rates — before you explore.

What happens when the promotional period ends

When the zero-interest or low-interest period expires, the card's regular balance transfer rate or purchase rate applies to any remaining balance. This rate varies by card and by your creditworthiness, but typically ranges from 12 to 25 percent. If you still owe $2,000 when the promotional period ends and the new rate is 18 percent, you will pay roughly $30 per month in interest alone.

Some cards give you a warning — an email or statement message — a few weeks before the promotional period ends. Use that time to decide whether to pay off the remaining balance, transfer it again to another card, or accept the higher rate. If you transfer again, you will pay another balance transfer fee, so the math needs to work a second time.

If you cannot pay off the balance before the promotional period ends and do not plan to transfer again, a balance transfer may not have been the right choice. In that case, you would have been better off keeping the debt on your original card or exploring other options like a debt consolidation loan or a nonprofit credit counseling service.

Alternatives to balance transfers

A balance transfer is not the only way to lower your interest rate. A personal loan from a bank or credit union often charges a fixed rate of 8 to 15 percent, depending on your credit score and the loan term. Unlike a balance transfer, a personal loan has a set payoff date — usually 2 to 7 years — so you know exactly when you will be debt-free. The downside is that you pay interest for the entire loan term, not just a promotional period.

A debt consolidation loan works similarly: you borrow money to pay off multiple debts, then repay the loan over time. The advantage is simplicity — one payment instead of many — but the total interest paid may be higher if the loan term is long.

If you are struggling with debt, a nonprofit credit counseling agency can review your situation and help you create a repayment plan. Many offer this service for free or a small fee. You can find a counselor through the National Foundation for Credit Counseling (nfcc.org) or the Financial Counseling Association (fcaa.org).

Frequently Asked Questions

Can I transfer a balance if I have bad credit?

You can explore, but approval is unlikely if your score is below 620. If you are approved, the promotional rate will be shorter or the regular rate higher. Some cards designed for fair credit offer 0 percent for 6 months instead of 18, or charge 16 percent after the offer ends instead of 12 percent.

How long does a balance transfer take?

The transfer usually posts within 5 to 7 business days after you request it. Some issuers are faster — 1 to 3 days — but a few take up to 14 days. Check your new card's terms or call customer service to ask about their timeline before you request the transfer.

Can I transfer a balance from a store card or a card from a different bank?

Yes. You can transfer from any credit card, store card, or line of credit. The issuer of your new card will contact the old issuer directly to arrange payment. You do not need to do anything with the old card except stop using it.

What happens if I make a new purchase on the balance transfer card during the promotional period?

It depends on the card. Some cards offer 0 percent on both transfers and purchases for the full promotional period. Others charge 0 percent on transfers but regular interest (12 to 25 percent) on new purchases when ready. Check the card's terms before you explore, and avoid new purchases if the promotional rate does not cover them.

Can I transfer a balance to a card I already own?

Yes, if the card issuer allows it. Not all issuers permit transfers between their own cards, so call customer service and ask. If they do allow it, the transfer fee still applies, and the promotional rate (if any) is the same as for a new card.
