A balance transfer moves your debt from one card to another, usually one with a lower interest rate

A balance transfer is when you move the money you owe on one credit card to a different card, typically one offering a lower interest rate for a set period. The new card's issuer pays off your old balance, and you then owe that amount to them instead. Most balance transfers come with an introductory rate — often 0% APR — that lasts anywhere from 6 to 21 months, depending on the card and the offer.

The catch is a transfer fee, usually 3% to 5% of the amount you move. So if you transfer $5,000 at 4%, you pay $200 upfront. That fee gets added to your new balance. The math still works in your favour if the introductory rate is low enough and you pay down the balance before the regular rate kicks in, but you need to do the calculation yourself — the card issuer will not tell you whether it makes sense for your situation.

Balance transfers work best when you have a concrete plan to pay off the debt during the 0% period. If you straightforward move the balance and keep spending, you end up with more debt at a higher rate once the introductory period ends.

Key Takeaways

  • Balance transfers charge a fee (usually 3% to 5%) added to your new balance, so calculate whether the savings on interest outweigh that cost.
  • The 0% introductory rate lasts only for a set period — typically 6 to 21 months — after which the regular APR applies to any remaining balance.
  • You must stop using the old card and ideally close it after the balance is paid, or you risk running up new debt on both cards.
  • The new card issuer handles the payment to your old card, but you should confirm the transfer posted before assuming the old balance is gone.

Check your credit score and find cards offering balance transfer rates

Balance transfer cards are not offered to everyone. Most require a credit score of 670 or higher, and the best introductory rates go to people with scores above 740. Before you search for a card, check your own score through your bank, a free service like Credit Karma, or by requesting your annual free credit report from Equifax or TransUnion.

Once you know your score range, search for balance transfer cards that match it. Major issuers like Chase, TD, RBC, and Scotiabank all offer balance transfer products, but the introductory rates and lengths vary. Read the fine print on each card's website — the rate, the length of the promotional period, the transfer fee, and any limits on how much you can transfer. Some cards cap transfers at a percentage of your credit limit; others have a flat maximum.

Compare at least three cards before explore. The difference between a 12-month 0% offer and a 21-month offer is significant if you are paying down a large balance slowly. Similarly, a 3% fee versus a 5% fee on a $10,000 transfer is $200 — money worth finding.

explore for the new card and request the balance transfer

Once you have chosen a card, explore through the issuer's website or by phone. The approval process usually takes a few business days. Some issuers let you request the balance transfer as part of the process; others require you to explore for the card first and then request the transfer separately once you are approved.

When you request the transfer, you will need the account number of the card you are transferring from, the amount you want to move, and the name and address of the old card's issuer. The new card issuer will contact your old card company and arrange the payment. This process typically takes 5 to 14 business days, though it can occasionally take longer.

Do not close your old card when ready. Wait until the transfer has posted to your new card and you can confirm the old balance is zero. Closing a card too quickly can hurt your credit score and may cause the transfer to fail if the old issuer tries to reverse it.

Understand what happens when the introductory period ends

The 0% rate is temporary. When the promotional period ends, any remaining balance on the new card will be charged the regular APR — often 19% to 22% for balance transfer cards. If you have not paid off the full amount by then, you will owe interest on whatever is left.

To avoid this, calculate how much you need to pay each month to clear the balance before the rate changes. If your introductory period is 18 months and you owe $6,000, you need to pay roughly $333 per month to finish before interest kicks in. Build that into your budget before you explore.

Mark the end date of the promotional period on your calendar. Some people set a phone reminder three months before it ends so they can reassess whether they will finish paying on time. If it looks like you will not, you might be able to transfer the remaining balance to another 0% card — though this only works if your credit score remains strong and you have not missed any payments.

Stop using the old card and manage both accounts carefully

Once the balance transfer is complete, do not use the old card. If you keep charging on it while paying down the transferred balance, you end up with debt on two cards and lose track of your payoff plan. The old card's issuer may also close the account if it sits unused for too long, which can affect your credit score.

The best approach is to close the old card once the balance hits zero and you have confirmed no pending charges are coming. Call the issuer, confirm the balance is paid in full, and ask them to close the account. Get a confirmation number. Do this in writing if possible — a phone call alone may not create a record.

On the new card, set up automatic payments for at least the minimum due each month, but ideally for the full amount you calculated earlier. Automatic payments prevent missed important date, which would trigger a penalty APR and damage your credit score. Missing even one payment during the promotional period can end the 0% rate when ready on some cards.

Watch for balance transfer limits and credit limit issues

Not all of your old balance may transfer. Some cards limit transfers to 95% of your credit limit, or they may have a flat cap — for example, a maximum of $25,000 per transfer. If your old balance exceeds the limit, the remainder stays on the original card at the original rate.

Your new card's credit limit also affects how much you can move. If you have a $10,000 credit limit on the new card and you want to transfer $8,000, you will have only $2,000 of available credit left for other purchases. This matters because credit utilization — the percentage of your limit you are using — affects your credit score. Using more than 30% of your available credit can lower your score.

Before requesting a transfer, check your new card's credit limit and calculate whether the transfer leaves you with enough room to avoid high utilization. If the limit is too low, you can request an increase before transferring, though this may trigger a hard inquiry on your credit report.

Calculate whether a balance transfer actually saves you money

The math is straightforward but straightforward to skip. Write down three numbers: your current balance, the interest rate you are paying now, and the transfer fee you will owe.

Use an online balance transfer calculator or do it by hand. Multiply your balance by your current APR and divide by 12 to find your monthly interest charge. Multiply that by the number of months until your promotional period ends. That is the interest you would pay if you did nothing. Then subtract the transfer fee from that number. If the result is positive, the transfer saves you money.

Example: You owe $5,000 at 22% APR. Your monthly interest is roughly $92. Over 18 months, that is $1,656 in interest. A balance transfer card charges 4% ($200) and offers 0% for 18 months. You save $1,456 — but only if you pay off the full $5,200 (balance plus fee) within 18 months. If you do not, the math reverses and you lose money.

Frequently Asked Questions

Does a balance transfer hurt my credit score?

Yes, temporarily. The new card process triggers a hard inquiry, which lowers your score by a few points. Opening a new account also lowers your average account age. However, the transfer itself reduces your utilization on the old card, which helps your score. The net effect is usually a small dip that recovers within a few months if you make on-time payments.

What if I cannot pay off the balance before the 0% period ends?

The remaining balance will be charged the regular APR, which is typically 19% to 22%. You can try to transfer the remaining balance to another 0% card, but this only works if your credit score is still strong and you have not missed any payments. Each transfer also charges a fee, so this strategy only makes sense if the new card's rate and length justify the cost.

Can I transfer a balance from a card issued by the same bank?

Most banks do not allow transfers between their own cards. You will need to transfer to a card from a different issuer. Check the card's terms before explore to confirm it accepts transfers from your current card's bank.

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

Most transfers post within 5 to 14 business days, though some take up to 21 days. During this time, you still owe the old card issuer. Keep making minimum payments on the old card until the transfer clears and you can confirm the balance is zero.

Should I close my old card after the balance transfers?

Yes, once the balance is confirmed at zero and no pending charges are coming. Closing the account prevents you from running up new debt on it. However, wait until the transfer has fully posted before closing — closing too early can cause the transfer to fail or reverse.
