What to look for in a balance transfer card
A balance transfer card is useful only if it saves you money on interest. The three numbers that matter are the introductory APR (the interest rate during the promotional period), the length of that period (usually 6 to 21 months), and the balance transfer fee (typically 3 to 5 percent of what you move). A card with a 0% intro APR for 18 months and a 3% fee is better than one with 0% for 12 months and a 5% fee, because you have more time to pay down the balance before interest kicks in.
The regular APR that kicks in after the intro period also matters, especially if you cannot pay off the full balance in time. Cards marketed for balance transfers often have regular APRs between 16% and 28%, depending on your credit score. Check what the card issuer says the regular APR will be before you move any money.
You will also want to know whether the card charges an annual fee. Most balance transfer cards do not, but some premium cards do. If the annual fee is $95 or higher, the math has to work very clearly in your favor for it to be worth it.
Key Takeaways
- The best balance transfer card for you depends on how long you need to pay off the debt and what your credit score is, because both affect the intro APR length and the regular APR you will face later.
- A 0% intro APR for 18 months with a 3% balance transfer fee usually saves more money than a shorter 0% period with a lower fee, because you have more months to pay without interest.
- After the intro period ends, interest charges resume at the regular APR, so read what that rate will be before you transfer a balance.
- Most balance transfer cards have no annual fee, but some do — factor that into whether the card actually saves you money.
- You can only transfer a balance if the card issuer approves you, which depends on your credit score and payment history.
Cards with longer 0% intro periods
If you have good to excellent credit (usually a score of 670 or higher), you may see intro periods of 18 to 21 months with 0% APR. Citi, Chase, and American Express each offer cards in this range. The longer the intro period, the more months you have to pay down the balance before interest charges begin. A 21-month window gives you nearly two years to work with.
These longer-period cards typically charge a 3% balance transfer fee, sometimes waived for the first 60 days if you move the balance quickly. The regular APR after the intro period usually falls between 16% and 24%, depending on your credit at the time of approval. If you know you can pay off most or all of the balance within the intro period, a longer window is worth the 3% fee upfront.
Cards with lower balance transfer fees
Some cards charge only 1% or 2% to move a balance, which is lower than the standard 3% to 5%. These cards tend to have shorter intro periods — often 6 to 12 months at 0% APR — so the lower fee compensates for less time to pay. A 1% fee on a $5,000 balance costs $50, while a 3% fee costs $150, a meaningful difference if your balance is large.
Lower-fee cards are most useful if you can pay off the balance in 6 to 12 months anyway, or if your balance is small enough that the fee difference is not significant. They are also a reasonable choice if your credit score is lower and you cannot get approved for the longest intro periods — you still get a 0% window, just a shorter one.
Cards with no balance transfer fee
A small number of cards waive the balance transfer fee entirely, though these are rare and usually come with trade-offs. The intro APR period may be shorter (6 to 12 months), or the regular APR after the intro period may be higher. Some cards waive the fee only if you transfer the balance within the first 60 days of opening the account.
A no-fee card makes sense if your balance is very large — a 3% fee on $20,000 is $600, so even a shorter intro period might be worth it to avoid that cost. Check the fine print carefully, because "no balance transfer fee" sometimes applies only to transfers made in a specific window, not to all transfers on the card.
How to compare cards side by side
Create a straightforward spreadsheet with the card name, intro APR length, balance transfer fee, and regular APR. Then do the math: multiply your balance by the fee percentage to see the upfront cost, and estimate how much you could pay down each month. If you can pay $500 a month on a $5,000 balance, you need 10 months without interest to clear it — so an 18-month intro period gives you 8 months of cushion, while a 12-month period gives you only 2.
Next, calculate what happens if you do not pay off the full balance by the time the intro period ends. Take the remaining balance, multiply it by the regular APR, and divide by 12 to see the monthly interest charge. A $2,000 balance at 20% APR costs about $33 per month in interest. If you are not confident you can clear the balance in time, a longer intro period is worth more than a lower fee.
Cards for people with fair or lower credit
If your credit score is below 670, you may not be approved for the longest intro periods or the lowest fees. Cards marketed to fair-credit borrowers often have intro periods of 6 to 12 months at 0% APR, with balance transfer fees of 3% to 5%. The regular APR after the intro period is often higher — sometimes 22% to 28% — because the issuer sees you as higher risk.
Even with these less favorable terms, a balance transfer card can still save money if you are currently paying 25% or higher on an existing card. Moving a balance to 0% for 12 months, even with a 3% fee, costs less than 12 months of interest at 25%. Focus on cards that report to the credit bureaus, because making on-time payments can help improve your score over the intro period.
What happens after the intro period ends
When the 0% APR period expires, interest charges resume at the regular APR. If you still have a balance, you will start paying interest on the remaining amount. This is why the regular APR matters: if you have $3,000 left and the regular APR is 24%, you will owe about $60 per month in interest alone.
Some people move a balance to a second card before the first intro period ends, a strategy called "balance transfer stacking." This works only if you have good credit and can get approved for another card with a new intro period. Each transfer costs a fee, so the math has to work — you need enough time and low enough fees to make it worthwhile. Most people are better off focusing on paying down the balance during the intro period rather than chasing new cards.
Frequently Asked Questions
Can I transfer a balance from one card to another card from the same bank?
Most banks do not allow you to transfer a balance between their own cards. For example, you usually cannot move a balance from one Chase card to another Chase card. Check the card's terms before you explore, or call the issuer to confirm.
Does a balance transfer hurt my credit score?
A balance transfer involves a hard inquiry and a new account, both of which can lower your score slightly in the short term. However, moving a balance also lowers your credit utilization (the percentage of available credit you are using), which can raise your score over time. The net effect is usually a small dip followed by improvement.
What if I cannot pay off the balance before the intro period ends?
Interest will begin accruing at the regular APR on any remaining balance. You can continue paying the card normally, or you can try to transfer the remaining balance to another card with a new intro period — though this costs another balance transfer fee and requires approval.
Do I have to use the card for new purchases?
No. You can transfer a balance and never use the card for anything else. However, if you do make new purchases, those usually accrue interest when ready at the regular APR, not at the 0% intro rate. Keep new purchases off the card during the intro period if you want to focus on paying down the transferred balance.
How long does a balance transfer take to show up?
Most balance transfers take 5 to 14 business days, though some can take up to 21 days. During this time, you are still responsible for payments on the old card. Continue making at least the minimum payment until the transfer is complete and shows on your new card statement.
