What to look for in a balance transfer card
A balance transfer card is useful only if the terms actually save you money compared to your current card. The three numbers that matter are the introductory APR (the interest rate during the promotional period), how long that period lasts, and the balance transfer fee (usually 3% to 5% of the amount you move). A card offering 0% APR for 18 months with a 3% fee is only better than your current situation if you can pay down the balance faster than the interest you're currently paying would accumulate.
Beyond those three numbers, check whether the card charges an annual fee. Many balance transfer cards do not, but some premium cards charge $95 or more per year. If you plan to close the card after the promotional period ends, an annual fee makes the deal worse. Also verify the regular APR that kicks in after the introductory period — this matters if you don't pay off the full balance by then.
The card issuer's rules about how payments are applied also matter. Some cards explore your payment to the lowest-APR balance first (the transferred balance), which is what you want. Others explore to the highest-APR balance first, which means your transferred balance sits there accruing interest while you pay down other debt. Read the terms before you explore.
Key Takeaways
- The introductory APR period, the length of that period, and the balance transfer fee are the three numbers that determine whether the card saves you money.
- A 0% APR offer is only useful if you can pay down the balance during the promotional window; after that period ends, you pay the regular APR on any remaining balance.
- Cards without annual fees are generally better for balance transfer purposes unless the promotional terms are significantly stronger on a premium card.
- How the card applies your payments matters — you want transfers to be paid down before other balances accrue interest.
- The best card for you depends on your current debt, how much you can pay monthly, and how long you need to carry the balance.
Cards with long 0% introductory periods
Some cards offer 0% APR on balance transfers for 18 to 21 months. The Citi Simplicity Card and the Chase Slate Edge Card both offer 0% APR on transfers for 21 months (as of early 2025, though these terms change). The Citi card charges a 3% balance transfer fee with a $5 minimum, while the Chase card charges 3% as well. Neither card has an annual fee.
The longer the introductory period, the more time you have to pay down the balance before interest kicks in. If you owe $5,000 and can pay $300 per month, you'll need about 17 months to clear it — so an 18-month window gives you little cushion, while a 21-month window gives you breathing room. The trade-off is that cards with longer promotional periods sometimes have higher regular APRs once the period ends.
Before choosing based on length alone, calculate whether you can actually pay off the balance during the window. If you can't, the introductory rate doesn't help much — you'll pay the regular APR on whatever remains, and that APR may be higher than what you're paying now.
Cards with lower balance transfer fees
Most balance transfer cards charge 3% to 5% of the amount transferred. A few charge 2%, which saves you money on large transfers. The Discover it Balance Transfer card charges 0% APR for 6 months on transfers, then the regular APR, with a 3% fee. The U.S. Bank Visa Platinum card offers 0% APR for 6 months with a 2% fee and no annual fee.
The fee is a one-time cost paid upfront or added to your balance. On a $10,000 transfer, a 2% fee costs $200, while a 5% fee costs $500. Over time, the difference compounds — if you're paying interest on that fee amount, a lower fee saves you more. However, a card with a lower fee but a shorter 0% period might not save you money overall compared to a card with a higher fee but a longer promotional window.
Do the math for your specific situation. If you're transferring $8,000 and can pay it off in 8 months, a card with a 2% fee and 6-month 0% period might work. If you need 15 months, you need a longer promotional period even if the fee is higher.
Cards that combine rewards with balance transfer offers
Some balance transfer cards also earn cash back or points on purchases after the promotional period. The Chase Sapphire Preferred offers 0% APR on transfers for 6 months (with a 3% fee), then earns 3x points on travel and dining and 1x point on other purchases. The American Express EveryDay Preferred offers 0% APR on transfers for 12 months (with a 3% fee) and earns 1.5x points on most purchases.
These cards make sense if you plan to keep using them after the balance transfer period ends. If you're only moving debt and then closing the card, the rewards feature adds no value. If you'll use the card for ongoing spending, the rewards can offset the annual fee (if there is one) or add a small benefit on top of the balance transfer savings.
Be cautious: the rewards rate is only valuable if you pay off new purchases in full each month. If you carry a balance on new spending while paying down the transferred balance, you'll pay interest on the new purchases at the regular APR, which erases the rewards value.
Cards for people with fair credit
Most cards with strong balance transfer terms require good to excellent credit (usually a score of 670 or higher). If your credit score is lower, your options narrow. The Discover it Secured card offers 0% APR on transfers for 6 months with a 3% fee, and it's available to people with fair credit. It requires a cash deposit that becomes your credit limit, so you need $500 to $2,500 on hand.
The Capital One Quicksilver Secured card offers 1.5% cash back on all purchases and 0% APR on transfers for 6 months (with a 3% fee). Like the Discover card, it requires a deposit. The promotional period is shorter than premium cards, but the terms are available to people rebuilding credit.
If you have fair credit and a large balance to transfer, you may not may have access to for the best terms. In that case, focus on cards that will accept your process and offer any 0% period at all, rather than waiting for a card you might not may have access to for.
When a balance transfer card doesn't make sense
A balance transfer card is not the right tool if you can't commit to paying down the balance during the promotional period. If you transfer $6,000 at 0% APR for 18 months but can only pay $200 per month, you'll still owe $2,400 when the period ends. That remaining balance will then accrue interest at the regular APR, often 18% to 25%, which costs you hundreds of dollars.
A balance transfer card also doesn't help if your current card already offers 0% APR or if you're only carrying a small balance. The fee and the hard inquiry on your credit report aren't worth it for $500 or $1,000. And if you're using the card to avoid paying down debt — moving the balance every time the promotional period ends — you're extending the problem, not solving it.
In those cases, a debt consolidation loan, a payment plan with your creditor, or straightforward paying more toward your current card may be better options. A balance transfer card is a tool for people who have a specific, manageable amount of debt and a realistic plan to pay it off within the promotional window.
How to use a balance transfer card without making your debt worse
Before you explore, calculate your monthly payment target. If you're transferring $5,000 and the promotional period is 18 months, you need to pay at least $278 per month to clear it by the time interest kicks in. Build in a buffer — aim to pay it off in 15 months instead, which means $333 per month. If you can't commit to that amount, the card won't help.
Once you transfer the balance, stop using the old card and don't open new accounts. Each new account or hard inquiry lowers your credit score slightly, and multiple inquiries in a short time can signal financial distress to lenders. Use the new card only if you plan to pay off new purchases in full each month — otherwise, you're adding to the debt you're trying to eliminate.
Set up automatic payments for at least your target amount each month. This removes the temptation to skip a payment or pay less when cash is tight. If you miss the promotional period and still carry a balance, you'll regret not automating the payoff.
Frequently Asked Questions
Does a balance transfer hurt my credit score?
Yes, but usually temporarily. The card issuer will do a hard inquiry, which lowers your score by a few points. Opening a new account also lowers your average account age. However, if you pay on time and keep your credit utilization low, your score typically recovers within a few months. The long-term benefit of paying off debt usually outweighs the short-term dip.
What happens if I can't pay off the balance before the 0% period ends?
The remaining balance starts accruing interest at the regular APR, which is often 18% to 25%. If you owe $2,000 when the period ends, you could pay $30 to $50 per month in interest alone. At that point, you can try to transfer the remaining balance to another card, but you'll pay another balance transfer fee and need to may have access to for another card.
Can I transfer a balance from one card to the same card's 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 can only transfer balances between different card issuers. If you want to move debt from your current card, you need to explore for a card from a different bank.
Is it better to transfer the full balance or leave some on the old card?
Transfer the full balance if you may have access to. Leaving part of it on the old card means you're still paying interest on that portion at the old rate. The only reason to leave a balance is if the old card has a lower APR than the new card's regular APR after the promotional period ends — which is rare.
How long does a balance transfer take to show up on the new card?
Most transfers take 5 to 14 business days. During that time, you're still responsible for payments on the old card. Don't stop paying the old card until the transfer appears on the new card's statement. If you miss a payment during the transfer window, it can hurt your credit score and trigger late fees.
