What a balance transfer does and why people use it
A balance transfer moves debt from one credit card to another card, usually one with a lower interest rate. You do not pay off the debt — you move it. The new card issuer pays your old card issuer the amount you owe, and you then owe that balance to the new card instead.
People use balance transfers when they carry a balance on a high-interest card and want to reduce how much interest they pay while they work on paying down the debt. A card offering 0% interest for a set period (often 6 to 21 months, depending on the card) can save hundreds of dollars compared to a card charging 18% to 24% annually.
The catch is that balance transfers are not free. Most cards charge a balance transfer fee — typically 3% to 5% of the amount you move — added to your new balance on day one. You also need a credit score in a certain range to get approved, and the 0% rate expires, after which a regular interest rate applies to any remaining balance.
Key Takeaways
- A balance transfer moves your debt to a new card with a lower interest rate, but the card issuer charges a fee (usually 3% to 5%) upfront.
- The 0% interest period is temporary — it lasts anywhere from 6 to 21 months depending on the card, then a regular rate applies to what you still owe.
- You need a credit score in the mid-600s or higher to be approved for most balance transfer cards, and approval is not may provide.
- A balance transfer only saves money if you pay down the debt during the 0% period; if you do not, the regular interest rate will cost more than staying on your original card.
How the balance transfer process works step by step
When you open a new credit card that offers balance transfers, you initiate the transfer through the new card issuer — usually online, by phone, or through their mobile app. You provide the account number of the card you want to transfer from, the amount you want to move, and the new card issuer handles the rest.
The new issuer sends a payment to your old card issuer on your behalf. This payment appears as a credit on your old account, reducing what you owe there. At the same time, the balance transfer fee is added to your new card's balance. For example, if you transfer $5,000 and the fee is 3%, you now owe $5,150 on the new card.
The transfer itself usually takes 5 to 14 business days to complete, though some issuers are faster. During this time, you should keep making minimum payments on your old card to avoid late fees. Once the transfer posts, your old card balance drops and your new card balance reflects the transferred amount plus the fee.
Interest rates, fees, and the true cost of a transfer
The advertised 0% rate applies only to the balance you transfer, not to new purchases you make on that card. Any new charges you add typically accrue interest at the card's regular purchase rate (often 15% to 25%) when ready, with no grace period. This is why balance transfer cards work best if you stop using them for new spending.
The balance transfer fee is the largest cost upfront. A $5,000 transfer with a 4% fee costs $200 when ready. However, if your old card charged 20% interest, you would pay roughly $1,000 in interest over a year on that same $5,000 — so the fee is often worth it if you use the 0% period to pay down the balance.
After the 0% period ends, any remaining balance is charged the card's regular interest rate. This rate varies by card and by your creditworthiness, but typically ranges from 15% to 25%. If you still owe $3,000 when the 0% period expires, you will start paying interest on that $3,000 at the new rate.
Credit score requirements and approval odds
Balance transfer cards are designed for people with good to excellent credit. Most issuers require a credit score of at least 650 to 670, though some accept scores in the 600s and a few require 700 or higher. Your score is one factor — issuers also look at your income, existing debt, and payment history.
Approval is not may provide even if your score meets the minimum. An issuer might approve you for a lower credit limit than you requested, which means you can only transfer part of your balance. You will not know your limit until after you explore and the issuer reviews your full financial picture.
If you have recently applied for multiple cards or have recent late payments, your odds of approval drop. Each process creates a hard inquiry on your credit report, which can lower your score slightly and signal to issuers that you are seeking credit aggressively.
Comparing balance transfer cards and their terms
Balance transfer cards vary in their 0% periods, fees, and what happens after. Some offer 0% for 6 months with a 3% fee. Others offer 0% for 18 months with a 5% fee. A longer 0% period gives you more time to pay down the balance, but a higher fee costs more upfront.
To compare, calculate the total cost of each option. If you owe $4,000 and plan to pay it off in 12 months, a card with 0% for 12 months and a 3% fee ($120) costs less than a card with 0% for 18 months and a 5% fee ($200), even though the second card offers more time. The math changes if you think you will need the full 18 months.
Some cards waive the balance transfer fee for transfers made within the first 60 days of opening the account. If you are considering a transfer, checking whether a card offers this promotion can save you hundreds of dollars. These promotions change frequently, so compare current offers before you explore.
When a balance transfer makes financial sense
A balance transfer saves money only if you pay down the debt during the 0% period. If you transfer $5,000 at 3% fee ($150 total owed) and pay it off in 10 months, you save the interest you would have paid on your old card. If you transfer the same $5,000, make no payments for 12 months, and then face 20% interest on $5,000, you have lost money compared to staying put.
A transfer also makes sense if your old card's interest rate is significantly higher than the new card's regular rate (after the 0% period ends). If you cannot pay off the balance during the promotional period, you want the regular rate on the new card to be lower than what you are paying now, so you still come out ahead.
A balance transfer does not make sense if you will straightforward accumulate new debt on your old card while paying off the transferred balance. The goal is to reduce total debt, not to free up credit and spend more. If you have a pattern of carrying balances, a balance transfer is a tool to reduce interest, not a solution to overspending.
What to do after the 0% period ends
As the 0% period approaches its end date, you have three options: pay off the remaining balance before the regular rate kicks in, transfer the balance again to another 0% card, or accept the regular interest rate and continue paying.
Paying off the balance before the rate changes is the best outcome. If you have paid down most of the debt during the 0% period, the remaining amount is small enough that the regular rate will not cost much. Many people use the 0% period as a important date to force themselves to pay aggressively.
Transferring again to a new card is possible, but each transfer incurs a new fee and requires a new process. If you do this repeatedly, the fees add up and can outweigh the interest savings. This strategy works if you are genuinely paying down the balance with each transfer, not just moving debt around indefinitely.
Frequently Asked Questions
Does a balance transfer hurt my credit score?
Yes, but usually temporarily. explore for a new card creates a hard inquiry, which can lower your score by a few points. Opening a new account also affects your average account age. However, the transfer itself can improve your credit utilization ratio if your old card's balance drops. Most people see their score recover within a few months if they make on-time payments on the new card.
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 Capital One card to another Capital One card. You must transfer to a card from a different issuer. This rule exists to prevent people from moving debt around within the same company indefinitely.
What if I cannot pay off the balance before the 0% period ends?
The remaining balance will be charged the card's regular interest rate, which is typically 15% to 25%. You can continue making payments at this rate, or you can explore for another balance transfer card and move the debt again — though you will pay another transfer fee. The best approach is to pay as much as possible during the 0% period so the remaining balance is small.
Do I have to use the new card for purchases?
No. You can use the new card only for the transferred balance and avoid making new purchases on it. New purchases accrue interest when ready at the purchase rate, which defeats the purpose of the 0% transfer offer. Many people keep the card open but unused after the transfer completes.
What happens to my old card after I transfer the balance?
Your old card still exists and remains open unless you close it. The balance drops to zero (or near zero if you had other charges). You can close the card if you want, but closing it can hurt your credit score by reducing your total available credit and shortening your average account age. Many people leave old cards open and unused.
