Balance transfer credit cards let you move high-interest debt to a card offering 0% APR for 12-21 months, saving hundreds or thousands in interest. Top options include Wells Fargo Reflect (21 months 0% APR), Citi Double Cash (18 months plus 2% cash back), and Chase Slate Edge (18 months with annual APR reductions). Most charge 3-5% balance transfer fees but eliminate interest charges during promotional periods if you pay on time.
You’re paying $200 monthly on a $6,000 credit card balance at 22% APR. At this rate, you’ll spend nearly three years paying off the debt and fork over $1,400 in interest charges. What if you could eliminate that interest entirely?
Balance transfer credit cards offer promotional 0% APR periods ranging from 12 to 21 months, during which every dollar you pay goes directly toward principal rather than interest. The right card can save you thousands while helping you become debt-free faster. The challenge lies in understanding transfer fees, meeting credit requirements, and choosing cards that match your repayment timeline.
This guide reveals which balance transfer cards offer the longest promotional periods, lowest fees, and best long-term value after the 0% APR expires. You’ll learn exactly how much you can save and avoid the common mistakes that cost people money.
How Balance Transfer Cards Actually Work?
Balance transfer cards function as debt consolidation tools that move your existing credit card balances to a new card offering significantly lower interest rates for a promotional period.
When you’re approved for a balance transfer card, you provide details about your current credit card debts—account numbers, amounts owed, and creditor information. The new card issuer pays off those balances directly, effectively buying your debt. Your old cards show zero balances, but you now owe that same amount to the new issuer. The key benefit is the promotional 0% APR period during which your balance stops accumulating interest charges.
Here’s what happens with your $6,000 debt example. Transfer it to a card with 18 months at 0% APR and a 3% transfer fee. You’ll pay a $180 fee upfront, making your starting balance $6,180. Divide that by 18 months and you need $343 monthly payments to eliminate the debt before regular rates kick in. You’ll pay $6,180 total—saving $1,220 compared to keeping the debt at 22% APR.
The transfer process takes one to two weeks to complete. During this time, you must continue making minimum payments to your old cards to avoid late fees and credit damage. Once the transfer finishes, your old cards are paid off but remain open unless you specifically close them. Keeping them open actually helps your credit score by maintaining your total available credit.
Not all debt qualifies for transfers. Most issuers won’t let you transfer balances between cards they issue—you can’t move Chase debt to another Chase card, for example. Some cards also limit transfers to credit card debt only, while others accept personal loans, auto loans, and even medical debt. Always verify what types of debt your target card accepts before applying.
Top Balance Transfer Cards Worth Considering
Current market leaders offer promotional periods ranging from 15 to 21 months with varying fee structures and rewards programs.
The Wells Fargo Reflect Card provides a 21-month 0% introductory APR on both purchases and balance transfers, making it the longest promotional period available. After that, rates range from 17.74% to 28.49% variable APR depending on creditworthiness. The balance transfer fee sits at 5%, higher than some competitors, but the extra months of interest-free repayment often justify the cost. You have 120 days after opening your account to complete transfers at the promotional rate.
The Citi Double Cash Card combines an 18-month 0% APR on balance transfers with long-term rewards value through its 2% cash back structure—you earn 1% when you buy and another 1% as you pay. The balance transfer fee is 3% for transfers within the first four months, jumping to 5% afterward. Regular APR ranges from 18.24% to 28.24% variable after the promotional period. This card makes sense when you want rewards earning potential after paying off your transferred balance.
Chase Slate Edge offers 18 months at 0% introductory APR on both purchases and balance transfers, with regular APR of 18.74% to 28.74% variable. The unique feature is automatic consideration for APR reductions—pay on time and spend at least $1,000 annually, and you could receive up to a 2% rate decrease each year. This matters significantly if you can’t pay off your balance during the promotional period.
Discover it Chrome delivers 18 months at 0% introductory APR on balance transfers plus category rewards—2% cash back at gas stations and restaurants up to $1,000 in combined quarterly purchases, and 1% on everything else. The intro balance transfer fee is 3%, increasing to 5% for future transfers. After the promotional period, APR ranges from 17.99% to 26.99% variable.
Chase Freedom Unlimited and Freedom Flex both offer 15-month 0% introductory APR periods with solid rewards programs. While shorter than alternatives, these cards provide excellent long-term value through their cash back structures—5% on rotating categories, 3% on dining and drugstores, and 1% on all other purchases. The shorter promotional window works if you can afford larger monthly payments to clear debt faster.

Understanding Balance Transfer Fees and Real Costs
Balance transfer fees typically range from 3% to 5% of the transferred amount, and this cost gets added to your new card balance immediately. Understanding whether the fee justifies the interest savings requires calculating your total costs under different scenarios.
Consider transferring a $10,000 balance currently charging 20% APR. With $300 monthly payments on your existing card, you’d pay $2,911 in interest over 47 months to eliminate the debt, totaling $12,911. Transfer that balance to a card with 18 months at 0% APR and a 3% fee. You’ll pay a $300 fee upfront, making your balance $10,300. Dividing by 18 months requires $572 monthly payments—higher than your current payment but doable. Your total cost is $10,300, saving you $2,611 in interest despite the transfer fee.
But what if you can’t afford $572 monthly? Say you stick with $300 payments on the balance transfer card. You’ll pay $5,400 during the 18-month promotional period, leaving a $4,900 balance when the regular APR kicks in at 19%. Continuing $300 payments for another 19 months adds $874 in interest, bringing your total cost to $11,174. You still save $1,737 compared to leaving the debt on your original card.
The math changes when your debt is small or your original APR is moderate. Transferring a $2,000 balance at 15% APR to a card with a 3% transfer fee costs you $60 upfront. If you plan to pay off the balance in six months anyway, you’d only pay about $90 in interest on the original card. The transfer fee nearly equals the interest savings, making the hassle questionable.
Missing even one payment during the promotional period can cancel your 0% rate and immediately cause interest rates to jump to 30% or more. Many cards include penalty APRs that apply when you’re 60 days late on payment. This effectively eliminates any savings from the balance transfer and leaves you worse off than before. Setting up autopay for at least the minimum payment protects you from this expensive mistake.
Credit Requirements and Approval Odds
Balance transfer offers are typically available only to consumers with good to excellent credit, usually meaning credit scores of 690 or better. However, credit scores alone don’t guarantee approval—issuers examine your income, existing debt levels, payment history, and recent credit activity.
Someone with a 720 credit score but a debt-to-income ratio exceeding 50% might face denial or receive a lower credit limit than requested. The issuer questions whether you can afford additional debt even at 0% APR. Conversely, a 680 score with strong income, low existing debt, and perfect payment history for two years might get approved because other factors outweigh the borderline credit score.
Recent credit activity heavily influences approval decisions. Applying for three credit cards in the past six months signals financial stress to underwriters. Each hard inquiry on your credit report temporarily lowers your score and suggests you’re desperately seeking credit. Space credit applications at least three to six months apart to avoid this red flag.
Your credit utilization ratio—the percentage of available credit you’re using—matters enormously. Someone using 85% of their available credit across all cards appears financially stretched. Even with good credit scores, high utilization suggests you’re barely managing current debt, making issuers hesitant to extend more credit. Ideally, keep utilization below 30% before applying, though this creates a catch-22 when you need a balance transfer specifically because your cards are maxed out.
Many issuers offer prequalification tools that let you check approval odds without impacting your credit score. These tools perform soft inquiries that don’t affect your score and provide preliminary decisions based on limited information. Successful prequalification doesn’t guarantee approval, but it indicates you meet basic requirements. Always prequalify before submitting formal applications to avoid unnecessary hard inquiries.
Creating a Payoff Plan That Actually Works
The promotional period only helps if you stay disciplined in paying off debt and avoid adding new charges to the balance transfer card. Without a structured payoff plan, you’ll find yourself owing a large balance when the 0% APR expires and regular rates apply.
Start by calculating your monthly payment requirement. Divide your total transferred balance by the number of promotional months, then add 10% buffer. If you transferred $8,000 to an 18-month 0% APR card, the minimum monthly payment is $444. Add 10% buffer and aim for $490 monthly. This buffer accounts for unexpected expenses that might force you to skip a month or make a smaller payment occasionally.
Create a dedicated checking account or use a separate savings account specifically for balance transfer payments. Set up automatic transfers from your main checking account to this dedicated account each payday. When the credit card payment is due, the money is already segregated and available, reducing temptation to spend it elsewhere. This psychological separation makes following through much easier.
Track your remaining balance weekly rather than monthly. Seeing progress in real-time motivates continued discipline. Use spreadsheets, budgeting apps, or simply a notebook where you log each payment and calculate remaining balance. Many people find that watching the number decrease week by week provides the motivation needed to avoid new debt and stick with the plan.
Avoid making new purchases on your balance transfer card. If you transfer a balance, interest will be charged on your purchases unless you pay your entire balance including balance transfers by the due date each month. This means carrying a transferred balance eliminates the grace period on new purchases, causing those purchases to accumulate interest immediately at the regular APR. Use a different card for new purchases you can pay off in full each month.
Plan ahead for the promotional period ending. Set calendar reminders for six months, three months, and one month before your 0% APR expires. These reminders let you assess whether you’ll pay off the balance in time or need to explore alternatives like another balance transfer or a personal loan to cover the remaining balance. Waiting until the last minute limits your options and might leave you stuck paying high interest on whatever remains.
Mistakes That Cost People Thousands
Common errors transform potentially money-saving balance transfers into expensive financial disasters that leave people worse off than before.
Not factoring in the balance transfer fee skews the comparison between the transfer cost and the interest cost of carrying debt. People see “0% APR” and assume they’ll save money without calculating whether the 3-5% upfront fee exceeds the interest they’d pay over their realistic payoff timeline. For small balances or short payoff periods, the transfer fee might cost more than the interest savings.
Continuing to use old credit cards after transferring balances creates a dangerous situation. Your paid-off cards have available credit again, tempting you to charge them up for purchases, emergencies, or other expenses. Within months, many people carry both the balance transfer card debt and new debt on their original cards. This pattern leaves you with even more debt to pay off, defeating the entire purpose of the balance transfer.
Underestimating required monthly payments leads to failure. People transfer $12,000 to an 18-month 0% APR card planning to “pay as much as possible each month.” Without calculating the exact payment needed—$667 monthly in this example—they make inconsistent payments averaging $400 and still owe $4,800 when the promotional period ends. That remaining balance then accrues interest at 20-25% APR, eliminating much of their savings.
Transferring balances from low-interest loans to credit cards rarely makes financial sense. Your car loan at 4.5% APR or student loans at 5.5% shouldn’t be transferred to credit cards, even at 0% APR for 18 months. The transfer fee alone costs more than several months of interest on the original loan, and you risk not paying off the balance before the regular credit card APR kicks in at 19-25%—much higher than your original loan rate.
Applying for multiple balance transfer cards simultaneously hoping one approves damages your credit through multiple hard inquiries and signals desperation. Each hard inquiry lowers your score by 3-10 points, and multiple applications within weeks compounds the damage. Worse, issuers reviewing your application see other recent credit applications and interpret this as financial distress, reducing your approval odds.
Maximizing Long-Term Value After Transfers
Successfully paying off your transferred balance doesn’t mean discarding the card. Many balance transfer cards offer long-term benefits worth keeping even after eliminating your debt.
Cards offering ongoing rewards programs provide value for years after your initial balance transfer. The Citi Double Cash Card’s 2% cash back on all purchases, Chase Freedom’s rotating 5% categories, or Discover it Chrome’s gas and dining rewards continue generating returns long after you’ve paid off transferred debt. Keep the card active with small monthly purchases you pay in full, earning rewards while building positive payment history.
Credit line increases become available after six to twelve months of on-time payments. Many issuers automatically review accounts for increases, while others let you request them. Higher credit limits improve your credit utilization ratio even if your spending doesn’t increase. Someone with a $5,000 balance across three cards totaling $15,000 in limits has 33% utilization. Increase those limits to $25,000 through strategic requests, and utilization drops to 20%—a significant credit score boost.
Some cards offer annual APR reductions for responsible use. Chase Slate Edge reduces your rate by up to 2% annually when you pay on time and spend at least $1,000. Over five years, this could lower your rate from 20% to 10%, providing substantial savings if you ever carry a balance in the future. This benefit only applies if you keep the card open and active.
Never close your balance transfer card immediately after paying it off unless it charges an annual fee. Closing credit cards shortens your credit history length and reduces your total available credit, both of which can lower your credit score. If the card charges no annual fee, keep it open with occasional small purchases to maintain positive payment history and available credit.
Consider whether to close your old cards after transferring balances. If they charge annual fees and you don’t use them, closing makes sense once the transferred balances are confirmed paid. However, no-annual-fee cards should generally stay open to preserve your credit history and available credit. Simply secure them in a drawer and don’t use them, or make one small recurring charge that autopays monthly.

Frequently Asked Questions
Can you do another balance transfer if you don’t pay off the balance in time?
Yes, you can transfer remaining balances to another 0% APR card before or after your promotional period ends, though this isn’t guaranteed to work. Card issuers examine your credit history, income, and payment patterns when you apply. If you’ve been paying consistently on your current balance transfer card and your credit score remains good, approval odds stay reasonable. However, repeatedly transferring balances every 12-18 months without making substantial progress signals to lenders that you’re avoiding debt rather than eliminating it. This pattern can lead to denials or reduced credit limits on future applications. The better strategy is committing to pay off the balance during your initial promotional period rather than planning to transfer again.
Do balance transfers hurt your credit score permanently?
Balance transfers create temporary credit score impacts through hard inquiries and changes to credit utilization, but these effects are rarely permanent. Applying for a new card generates a hard inquiry that lowers your score by 3-10 points for about 12 months. Opening the new account briefly lowers your average account age. However, paying down debt with the promotional period substantially lowers your credit utilization ratio, which typically outweighs the initial negative impacts. Most people see their scores return to or exceed pre-transfer levels within six months if they make on-time payments and avoid accumulating new debt. The long-term effect usually improves your credit by demonstrating responsible debt management and reducing overall balances.
Should you close your old credit cards after transferring the balance?
Keep old credit cards open unless they charge annual fees you can’t justify, especially when those cards have long credit histories. Closing cards reduces your total available credit, which increases your credit utilization ratio and can significantly lower your score. For example, if you have $30,000 in total credit limits and owe $6,000 after a balance transfer, your utilization is 20%. Close cards representing $15,000 in limits, and your utilization jumps to 40% on the same debt—a score-damaging increase. Closed accounts also stop contributing to your credit mix and eventually fall off your credit report, shortening your credit history length. If annual fees aren’t an issue, keep cards open with occasional small purchases that autopay monthly to maintain account activity.
Conclusion
Balance transfer credit cards offering 0% APR periods up to 21 months can save you thousands in interest charges while helping you eliminate credit card debt faster. The best balance transfer cards combine long promotional periods with reasonable transfer fees and valuable rewards programs that provide ongoing benefits after you’ve paid off transferred balances. Wells Fargo Reflect leads with 21 months interest-free, while Citi Double Cash and Chase Slate Edge offer 18-month periods plus additional perks.
Success requires calculating your exact monthly payment needs, avoiding new debt during the promotional period, and making consistent payments that eliminate your balance before regular APRs apply. The 3-5% transfer fee typically justifies the savings when you’re paying off significant high-interest debt over 12-18 months. Compare multiple cards using prequalification tools before applying, create a realistic payoff plan before transferring, and commit to changing the spending habits that created the debt originally.
