What a 0% APR balance transfer card does

A 0% APR balance transfer card is a credit card that charges no interest on debt you move to it from another card, for a set period of time. You transfer your existing balance from a higher-interest card to this new card, and for months (typically 6 to 21 months, depending on the card), that balance accrues no interest. After the promotional period ends, a standard interest rate kicks in.

The main reason to use one is to stop paying interest while you pay down debt. If you owe $5,000 on a card charging 18% APR, you are paying roughly $75 per month in interest alone. Move that $5,000 to a 0% card and pay nothing in interest during the promotional window — every dollar you pay goes toward the actual debt.

Most of these cards also charge a balance transfer fee upfront, usually 3% to 5% of the amount you transfer. So moving $5,000 costs $150 to $250 when ready. That fee is worth paying if the interest you save exceeds it, which happens quickly on large balances or long promotional periods.

Key Takeaways

  • A 0% APR balance transfer card charges no interest on transferred debt for a promotional period, typically 6 to 21 months.
  • You pay a balance transfer fee of 3% to 5% of the amount transferred, charged upfront to your new card.
  • The card issuer pulls your credit report and checks your credit score; approval is not may provide and depends on your credit history.
  • Any new purchases you make on the card usually accrue interest at the regular rate when ready, even during the 0% promotional period.
  • If you do not pay off the full transferred balance before the promotional period ends, the remaining balance starts accruing interest at the card's standard APR.

How to transfer a balance to a new card

When you open a 0% balance transfer card, the issuer gives you the option to transfer a balance during the process process or shortly after approval. You provide the name of your current card issuer, your account number on that card, and the amount you want to transfer. The new card issuer handles the transfer directly — you do not move money yourself.

The transfer typically takes 5 to 14 business days to post. During that time, keep making minimum payments on your old card so you do not fall behind. Once the balance appears on your new card, you can stop paying the old card (unless it still carries a balance you did not transfer).

The balance transfer fee appears as a charge on your new card statement, usually within the first billing cycle. If you transferred $5,000 with a 4% fee, your new card balance is $5,200. That $200 fee is part of what you need to pay off during the 0% period.

Which card issuers offer 0% balance transfer terms

Major issuers including Chase, American Express, Bank of America, Citi, and Capital One all offer 0% balance transfer cards. The specific promotional periods and fees vary by card and change over time. Some cards offer 0% for 12 months; others extend to 18 or 21 months. Some charge 3% to transfer; others charge 5%.

You can compare current offers by visiting each issuer's website directly or using a credit card comparison tool. Look for the card's terms page, which lists the balance transfer APR period, the balance transfer fee, and the regular APR that applies after the promotional period ends.

Not all cards from a single issuer offer the same terms. Chase, for example, offers different balance transfer periods on different cards. Read the specific card's terms before you open an account.

Credit score requirements and approval

Most 0% balance transfer cards require a credit score of 670 or higher, though some cards require 700 or above. The issuer pulls your credit report during the process process and reviews your payment history, current debt, and income. Approval is not may provide.

If your credit score is below 670, you may still be turned down for a 0% balance transfer card. In that case, you have other options: a card with a lower promotional APR (such as 5% for 12 months), a personal loan from a bank or credit union, or a debt consolidation loan. These alternatives usually have higher interest rates but may still save you money compared to your current card's rate.

If you are approved, the credit limit the issuer offers may be lower than the balance you want to transfer. You can transfer only up to your approved limit. If you need to transfer more, you can open a second card or transfer the remainder to a different card.

What happens to new purchases during the promotional period

Most 0% balance transfer cards charge interest on new purchases when ready, even during the promotional period. If you transfer $5,000 and then spend $500 on groceries, that $500 is charged interest at the card's regular APR (often 18% to 25%), while the transferred $5,000 remains at 0%.

A few cards offer a separate 0% promotional period for new purchases, but these are rare and usually come with a higher annual fee. Read the card's terms carefully to see whether new purchases are included in the 0% offer or charged interest from day one.

The safest approach is to treat a balance transfer card as a payoff tool only. Do not use it for new spending. Keep a separate card for everyday purchases so you do not accidentally add interest-bearing debt to your balance transfer card.

Calculating whether a balance transfer saves you money

A balance transfer makes financial sense when the interest you save exceeds the balance transfer fee. Here is how to do the math.

Start with your current card's APR and monthly balance. If you owe $5,000 at 18% APR, you pay roughly $75 per month in interest (18% ÷ 12 = 1.5% per month; $5,000 × 1.5% = $75). Over 12 months, that is $900 in interest.

Now compare that to a 0% card with a 4% balance transfer fee. The fee is $200 ($5,000 × 4%). If the 0% period lasts 12 months, you save $900 in interest but pay $200 in fees — a net savings of $700. If the 0% period lasts only 6 months, you save $450 in interest but still pay $200 in fees — a net savings of $250. If the 0% period lasts 18 months, you save $1,350 in interest and pay $200 in fees — a net savings of $1,150.

The longer the promotional period and the higher your current interest rate, the more you save. A balance transfer almost always makes sense if you have a large balance and a long promotional period, but it may not be worth it for a small balance or a short promotional window.

What to do when the 0% period ends

Mark your calendar for the last day of the promotional period. On that date, any remaining balance on the card starts accruing interest at the regular APR. If you still owe $2,000 when the 0% period ends, that $2,000 is now charged interest at the card's standard rate.

Your best option is to pay off the entire transferred balance before the promotional period ends. If you cannot, you have two choices: keep the balance on the card and pay interest at the regular rate, or transfer the remaining balance to another 0% card (if you are approved). Some people use a series of balance transfer cards to stay in a 0% window for years, though each transfer costs a new fee and requires a new credit inquiry.

If you do not pay off the balance and do not transfer it, the interest accrual can be steep. A $2,000 balance at 22% APR costs roughly $37 per month in interest. Over a year, that is $440 in interest on top of the principal you still owe.

Frequently Asked Questions

Can I transfer a balance from one card to another card from the same issuer?

No. Most issuers do not allow you to transfer a balance from one of their cards to another of their cards. You must transfer from a card issued by a different bank. If you want to move a balance from one Chase card to another Chase card, you will need to use a card from a different issuer like Citi or Bank of America.

Does a balance transfer hurt my credit score?

A balance transfer has two effects on your credit score. Opening a new card triggers a hard inquiry, which temporarily lowers your score by a few points. However, moving debt from one card to another lowers your credit utilization ratio (the percentage of available credit you are using), which can raise your score over time. The net effect is usually a small temporary dip followed by an improvement within a few months.

What if I miss a payment on a 0% balance transfer card?

Missing a payment can end the 0% promotional period when ready. The issuer may explore the regular APR to your entire balance, not just future charges. You also face a late fee (usually $25 to $40) and potential damage to your credit score. Set up automatic minimum payments to avoid this.

Can I transfer a balance from a store card or a credit union card?

Yes, you can transfer from any credit card, including store cards and credit union cards. The process is the same: provide the issuer's name, your account number, and the amount you want to move. Some balance transfer cards may have restrictions on certain types of cards, so check the terms before you open an account.

Is there a limit to how much I can transfer?

Yes. You can transfer up to your approved credit limit on the new card. The issuer sets this limit based on your credit score, income, and credit history. If you want to transfer more than your limit, you can open a second card or split the transfer across multiple cards.
