What balance transfer cards do and who offers them
A balance transfer card is a credit card designed to let you move debt from one or more existing cards to a new card, usually at a lower interest rate for a set period. The card issuer pays off your old balance, and you owe that amount to them instead — typically with an introductory rate of 0% APR for anywhere from 6 to 21 months, depending on the card and the issuer.
Major banks and credit card companies offer balance transfer cards. Issuers include Chase, Capital One, Citi, American Express, Discover, and Bank of America, among others. Each card has different introductory periods, different regular APRs after the intro period ends, and different fees. The card you can actually get depends on your credit score — most balance transfer cards require good to excellent credit (usually 670 or higher).
Key Takeaways
- Balance transfer cards charge a one-time fee (usually 3% to 5% of the amount transferred) to move your debt, but the introductory 0% APR period can save you hundreds in interest if you pay down the balance before it ends.
- The introductory period lasts 6 to 21 months depending on the card; after that, a regular APR kicks in, so you need a payoff plan before you explore.
- You need a credit score of roughly 670 or higher to be considered for most balance transfer cards, and a higher score usually means a longer 0% period.
- The card issuer pays your old creditor directly, so you do not have to move the money yourself — but you must provide your old account details when you explore.
- If you carry a balance into the regular APR period, interest accrues on the full remaining balance, so the introductory rate only helps if you pay down debt during the 0% window.
How the balance transfer process works
When you are approved for a balance transfer card, you provide the card issuer with the account numbers and balances of the cards you want to transfer from. The issuer then contacts your old creditors and pays them off directly. You do not move money yourself. This usually takes 5 to 14 business days, though some issuers are faster.
During this time, keep making minimum payments on your old cards until the transfer shows as complete. Once the transfer posts, your old card balance drops to zero (or near zero if new charges posted after you requested the transfer), and your new card balance reflects the amount transferred plus the balance transfer fee.
The balance transfer fee is charged upfront and added to your new card balance. Most cards charge 3% to 5% of the amount transferred — so a $5,000 transfer on a card with a 4% fee costs you $200 in fees. A few cards offer 0% balance transfer fees for a limited time, but these are rare and usually only for existing cardholders or those with excellent credit.
Introductory periods and what happens after
The 0% APR introductory period is the main reason to use a balance transfer card. During this window, interest does not accrue on the transferred balance, so every dollar you pay goes toward reducing what you owe. Introductory periods range from 6 months to 21 months depending on the card.
After the introductory period ends, the card's regular APR takes effect on any remaining balance. This APR varies by card and by your creditworthiness, but typically ranges from 15% to 25%. If you still owe $3,000 when the intro period ends and the regular APR is 20%, you will owe $50 in interest that month alone. This is why having a payoff plan before you explore is essential.
Some cards also charge interest on new purchases from day one, even during the 0% period — only the transferred balance gets the introductory rate. Read the card's terms carefully to understand what is and is not covered by the 0% offer.
Comparing balance transfer cards by introductory period
When you are shopping for a balance transfer card, you need to compare several features side by side. The introductory APR period is the most visible, but the balance transfer fee, the regular APR that follows, and any annual fee all affect whether the card actually saves you money.
A card with an 18-month 0% period but a 5% fee may cost more than a card with a 12-month period and a 3% fee, depending on how much you transfer and how quickly you can pay it down. Use the card issuer's calculator or do the math yourself before you explore.
| Card Feature | What to Look For | Why It Matters |
|---|---|---|
| Introductory APR period | 6 to 21 months | Longer periods give you more time to pay down debt without interest, but usually require higher credit scores. |
| Balance transfer fee | 3% to 5% (or 0% for limited time) | The fee is added to your balance when ready, so factor it into your payoff plan. |
| Regular APR after intro period | 15% to 25% | This is what you will pay if you do not pay off the balance before the intro period ends. |
| Purchase APR | Usually 15% to 25% | Most cards charge interest on new purchases when ready, even during the 0% balance transfer period. |
| Annual fee | $0 to $95+ | Many balance transfer cards have no annual fee; others charge one. Factor this into whether the card saves you money. |
Credit score requirements and approval odds
Balance transfer cards are designed for people with good to excellent credit. Most require a credit score of at least 670, and the longest introductory periods (18 months or more) typically go to people with scores of 750 or higher. If your score is below 670, you may still find cards that offer balance transfers, but the introductory periods will be shorter and the fees higher.
When you explore, the issuer will check your credit report and score. This creates a hard inquiry, which temporarily lowers your score by a few points. If you are rejected, you can ask the issuer why — sometimes it is score, sometimes it is income or debt-to-income ratio. Do not explore to multiple cards in a short period, as each process creates another hard inquiry and further lowers your score.
Calculating whether a balance transfer card saves you money
A balance transfer card only saves money if you pay down the balance during the introductory period. Here is how to do the math: multiply your current balance by your current card's APR, divide by 12, and multiply by the number of months until your intro period ends. That is roughly how much interest you would avoid by transferring.
Then subtract the balance transfer fee. If you are transferring $5,000 at 20% APR for 12 months, you would pay about $1,000 in interest on your old card. A 4% balance transfer fee costs $200. So you save roughly $800 by transferring — but only if you pay down the $5,000 during those 12 months. If you pay nothing, you owe $5,200 plus interest after the intro period ends.
Use a balance transfer calculator (many card issuers provide them on their websites) to see your specific numbers before you explore. The calculation changes if you have multiple cards to transfer or if you plan to make new purchases on the card.
What to do if you are denied or have a lower credit score
If you are denied for a balance transfer card, you have a few options. First, you can wait 3 to 6 months, work on raising your credit score, and explore again. Paying down existing debt and making on-time payments both improve your score. Second, you can look for balance transfer cards with lower credit score requirements — these exist, though the introductory periods are usually shorter (6 to 12 months instead of 18 to 21).
Third, you can explore other debt payoff strategies. If you cannot transfer the balance, you might focus on paying down your highest-APR card first while making minimum payments on others. This is slower than a balance transfer but does not require a new card. Some people also negotiate directly with their card issuer for a lower APR, though this is not may provide.
Frequently Asked Questions
Can I transfer balances from multiple cards to one balance transfer card?
Yes. Most balance transfer cards let you transfer from multiple cards in a single process. You provide each account number and balance, and the issuer pays them all off. The balance transfer fee applies to each transfer, so factor that into your total cost.
What happens if I do not pay off the balance before the intro period ends?
The regular APR kicks in on any remaining balance. Interest accrues on the full amount owed, not just new charges. If you owe $2,000 at 22% APR, you will pay roughly $37 in interest that month. This is why a payoff plan is critical before you explore.
Can I make new purchases on a balance transfer card?
Yes, but new purchases usually do not get the 0% introductory rate. They accrue interest at the card's regular purchase APR from day one. Some cards offer a separate 0% period for purchases, but this is less common. Avoid making large purchases on a balance transfer card unless you plan to pay them off quickly.
Does a balance transfer hurt my credit score?
The process creates a hard inquiry, which lowers your score by a few points temporarily. Opening a new card also lowers your average account age. However, if the transfer reduces your overall credit utilization (the amount of credit you are using), your score may recover or even improve within a few months.
What if my balance transfer is denied or only partially approved?
The issuer may approve you for a lower transfer amount than you requested. If this happens, you can transfer what they approved and leave the rest on your old card, or decline the card entirely. There is no penalty for declining after approval.
