A balance transfer moves your debt from one card to another, usually to a card offering a lower interest rate for a set period

A balance transfer is a way to move an existing balance from one credit card to a different card, typically one with a lower interest rate. The new card issuer pays off your old balance, and you then owe that amount to the new issuer instead. Most balance transfer cards offer a promotional period — usually 6 to 21 months — during which you pay little or no interest on the transferred amount. After the promotional period ends, the regular interest rate kicks in.

Balance transfers work best if you have a plan to pay down the debt during the promotional period. If you transfer a balance but don't pay it off before the promotional rate expires, you'll start paying the card's standard interest rate, which can be as high as 20% or more. The transfer itself usually costs 3% to 5% of the amount you move, though some cards waive this fee during a promotional window.

Key Takeaways

  • Balance transfer cards typically offer 0% interest for 6 to 21 months, but charge a transfer fee of 3% to 5% unless the issuer is running a promotional offer.
  • You need to know your current balance, the interest rate you're paying now, and how much you can pay monthly to determine whether a transfer will actually save you money.
  • The transfer process takes 5 to 14 days after you open the new card, and you should not close your old card when ready because it can hurt your credit score.
  • If you can't pay off the balance before the promotional rate ends, the regular interest rate will explore to any remaining balance, potentially costing more than you save.

Calculate whether a balance transfer saves you money

Before you move a balance, do the math. Write down three numbers: your current balance, your current card's interest rate, and the monthly payment you can afford. Then look at the balance transfer card's promotional rate and length, and its transfer fee.

Use this formula: multiply your current balance by your current interest rate, then divide by 12 to see how much interest you pay per month. Now multiply that monthly interest by the number of months until your promotional period ends on the new card. That's the interest you'd pay if you stayed put. Next, add the transfer fee (3% to 5% of your balance) to see the total cost of moving. If the transfer fee plus zero interest for the promotional period costs less than the interest you'd pay on your current card, a transfer makes sense — but only if you can pay down the balance during that promotional window.

For example: a $5,000 balance at 18% interest costs about $75 per month in interest alone. Over 12 months, that's $900 in interest. A balance transfer card with a 4% fee ($200) and 12 months at 0% costs you $200 total. If you can pay $500 per month, you'd pay off the balance in 10 months and save roughly $700. But if you can only pay $200 per month, you won't finish before the promotional rate ends, and you'll owe interest on the remaining balance — making the transfer less worthwhile.

Find and open a balance transfer card

Balance transfer cards come from most major issuers: Chase, American Express, Citi, Bank of America, Capital One, and Discover all offer them. Compare the promotional period length, the transfer fee, and the regular interest rate that applies after the promotional period. Some cards waive the transfer fee for the first 60 or 90 days after opening, which can save you hundreds of dollars.

Once you've chosen a card, open it through the issuer's website or by phone. You'll need to provide your name, address, Social Security number, income, and employment information. The issuer will check your credit and give you a credit limit. This typically takes a few minutes to a few hours, though some decisions take up to a week.

After your new card arrives, you'll have a window — usually 60 to 120 days — to request the balance transfer. Don't wait. The sooner you request it, the sooner the promotional period begins counting down.

Request the balance transfer and track the process

To request a balance transfer, log into your new card's online account or call the issuer's customer service number. You'll need the account number of the card you're transferring from, the balance amount you want to move, and the name and address of that card's issuer. Some issuers let you request the transfer online; others require a phone call.

The transfer itself takes 5 to 14 days. During this time, the new card issuer contacts your old issuer, confirms the balance, and arranges payment. You'll see the transferred balance appear on your new card's statement within two weeks. Your old card's balance will drop to zero (or to whatever portion you didn't transfer).

Keep your old card open during and after the transfer, even though the balance is now zero. Closing it when ready can lower your credit score because it reduces your total available credit and shortens your credit history. Wait at least six months, or until the promotional period is nearly over, before closing the old card.

Avoid common mistakes during the promotional period

The biggest mistake is making new purchases on the balance transfer card. Most cards explore new purchases to a different interest rate — often 15% to 25% — and you must pay off the transferred balance before the new purchases are covered by the promotional rate. This means your monthly payment goes toward the new purchase first, leaving the transferred balance to accrue interest after the promotional period ends.

Another mistake is missing a payment. Even one late payment can end your promotional rate early and trigger a penalty interest rate, sometimes as high as 29%. Set up automatic payments for at least the minimum due, and aim to pay more if you can. Calculate what you need to pay monthly to clear the balance before the promotional period ends, and stick to that number.

Don't assume the promotional period is longer than it actually is. Mark the end date on your calendar. If you haven't paid off the balance by then, you'll owe the regular interest rate on whatever remains. Some cardholders transfer again to a new 0% card, but this only works if you can open new cards without damaging your credit and if you're disciplined about paying down the balance each time.

Understand what happens after the promotional period ends

When the promotional period expires, any remaining balance will be charged the card's regular interest rate. This rate varies by issuer and by your creditworthiness, but typically ranges from 15% to 25%. If you have a $2,000 balance remaining at 20% interest, you'll pay about $33 per month in interest alone.

If you know you won't pay off the entire balance before the promotional period ends, consider a different strategy. Some people use a balance transfer card to buy time while they pay down debt aggressively, then move the remaining balance to another 0% card before the first promotional period ends. This only works if you have good credit and can open new cards without excessive damage to your score. Each new card process triggers a hard inquiry, which temporarily lowers your score by a few points.

Alternatively, if the remaining balance is small, you might straightforward accept the regular interest rate and focus on paying it down as quickly as possible. The math depends on your situation: how much is left, how long until the rate kicks in, and how much you can pay monthly.

Balance transfers versus other debt-reduction options

A balance transfer is one way to reduce interest on credit card debt, but it's not the only way. A personal loan from a bank or credit union often carries a fixed interest rate of 6% to 12%, which may be lower than your current card's rate but higher than a 0% promotional period. The advantage of a personal loan is that the interest rate doesn't change, so you know exactly what you'll pay. The disadvantage is that you'll start paying interest when ready, whereas a balance transfer gives you months at 0%.

A debt consolidation loan works similarly to a personal loan but is designed specifically for combining multiple debts into one payment. If you have balances on several cards, consolidation might be simpler than doing multiple balance transfers.

If you have significant debt and a lower credit score, you might not be approved for a balance transfer card or a personal loan. In that case, a debt management plan through a nonprofit credit counselor might help. These plans don't reduce your debt, but they can lower your interest rates and consolidate your payments into one monthly amount.

Frequently Asked Questions

Does a balance transfer hurt my credit score?

Yes, but usually only temporarily. Opening a new card triggers a hard inquiry, which lowers your score by a few points for a few months. The new account also lowers your average account age. However, the transfer itself reduces your credit utilization on your old card, which can help your score. Overall, the impact is usually small and recovers within 6 to 12 months if you pay on time.

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

No. You cannot transfer a balance from a Chase card to another Chase card, or from a Citi card to another Citi card. You must transfer to a card from a different issuer. This is a rule set by the card networks, not the individual issuers.

What if I don't have enough credit limit on the new card to transfer my full balance?

You can transfer a partial balance — whatever fits within your credit limit — and leave the rest on your old card. You'll continue paying interest on the portion that stays behind. You can request a credit limit increase on the new card after a few months of on-time payments, then transfer the remaining balance if the issuer approves the increase.

Can I transfer a balance if I'm behind on payments?

Most issuers will not approve a balance transfer if your account is currently delinquent. You'll need to bring your account current first. If you're struggling to make payments, contact your current issuer to discuss hardship options before explore for a new card.

What happens to my old card after the balance is transferred?

Your old card will show a zero balance, but the account remains open. You can use it for new purchases if you want, though it's usually better to avoid using it during the promotional period so you don't mix transferred debt with new purchases. Keep the card open for at least six months to avoid damaging your credit score.
