What a 0% balance transfer card does

A 0% balance transfer credit card is a card that charges no interest on debt you move to it from another card, for a set period of time. You transfer an 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 regular interest rate kicks in on any remaining balance.

The catch is that most of these cards charge an upfront balance transfer fee — usually 3% to 5% of the amount you move. So if you transfer $5,000, you might pay $150 to $250 just to move it. That fee is added to your new balance on the card.

These cards are useful if you have high-interest debt (like a regular credit card charging 18% to 25%) and you can pay down the balance during the interest-free window. They are not useful if you plan to carry the balance past the promotional period, because the regular rate will be higher than what you started with.

Key Takeaways

  • A 0% balance transfer card charges no interest on moved debt for a promotional period, usually 6 to 21 months, but adds a one-time transfer fee of 3% to 5%.
  • You must transfer the balance from another card within a set window (often 60 days of opening the account) to lock in the 0% rate.
  • After the promotional period ends, any remaining balance is charged the card's regular interest rate, which is typically 15% to 25%.
  • The math only works in your favor if you pay down most or all of the balance before the 0% period expires.
  • You cannot transfer a balance from one card issued by the same bank to another card from that same bank.

How to move a balance to a 0% card

When you open a 0% balance transfer card, the issuer gives you a window to complete the transfer — usually 60 days. You do not move the money yourself. Instead, you tell the new card issuer the name of the old card, the account number, and the amount you want to move. The new issuer contacts the old card company and arranges the transfer directly.

You will need the account number and issuer name of the card you are transferring from. Have that information ready when you explore. Some issuers let you start the transfer during the process process; others send you a form or a link after your account opens.

The transfer usually posts within 7 to 14 days. During that time, keep making at least the minimum payment on your old card, because the balance is still there until the transfer completes. Once the transfer posts to the new card, you can stop using the old card (though you may want to keep it open to preserve your credit history).

Understanding the transfer fee and the math

The balance transfer fee is not optional — it is charged automatically when you move the balance. A $5,000 transfer at 4% costs $200. That $200 is added to your new balance, so you now owe $5,200 on the 0% card.

To decide whether a balance transfer makes sense, compare the fee plus what you would pay in interest during the promotional period against what you would pay if you stayed with your current card. If your current card charges 20% interest and you can pay off the balance in 12 months, the 0% card saves you money even after the transfer fee. If you plan to carry the balance for years, the savings shrink.

Use a calculator: take your current balance, multiply it by your current interest rate, and divide by 12 to estimate your monthly interest cost. Then compare that to the transfer fee. If the transfer fee is less than three months of interest on your current card, a balance transfer is probably worth considering.

What happens when the 0% period ends

When the promotional period expires, any balance still on the card is charged the card's regular interest rate. That rate is set by the issuer and varies by creditworthiness, but typically ranges from 15% to 25%. You will see the rate listed in the card's terms and conditions before you open the account.

The goal is to pay off the entire balance before the 0% period ends. If you cannot, at least pay down as much as you can. Every dollar you pay off during the promotional period is a dollar that will not be charged interest later.

Some people use a second 0% balance transfer card to move the remaining balance again, but this only works if you have good credit and can open another card. Each transfer incurs another fee, so this strategy only makes sense if the new card's fee and promotional period are better than the interest you would pay on the old card.

Who can get a 0% balance transfer card

Most 0% balance transfer cards require good to excellent credit — typically a credit score of 670 or higher. Cards with longer promotional periods (18 to 21 months) usually require scores of 740 or higher. If your score is below 670, you may not be approved, or you may be approved with a shorter promotional period and a higher fee.

You must also have an active credit history. Issuers want to see that you have used credit before and paid your bills on time. If you are new to credit or have a history of missed payments, approval is less likely.

There is no income requirement, but the issuer will verify your income during the process process. They use this to set your credit limit, which must be high enough to cover the balance you want to transfer.

Restrictions and things to watch for

You cannot transfer a balance from a card issued by the same bank. If you have a Chase card, you cannot transfer that balance to another Chase card. You can only transfer between different issuers.

Some cards limit how much you can transfer. The limit is usually your credit limit minus any fees, or a percentage of your credit limit. If you want to transfer $10,000 but your credit limit is $8,000, you can only transfer $8,000 (minus the transfer fee).

Balance transfers do not count as a new purchase. If you make a purchase on the card during the promotional period, that purchase is charged interest when ready at the regular rate, even though your transferred balance is at 0%. Pay off the transferred balance first, then use the card for new purchases only after the 0% period ends.

Opening a new card temporarily lowers your credit score because the issuer runs a hard inquiry and you have a new account with no history. The score usually recovers within a few months if you make on-time payments.

Alternatives to a 0% balance transfer card

If you do not may have access to for a 0% card or do not want to open a new account, other options exist. A personal loan from a bank or credit union often charges lower interest than a credit card and has a fixed repayment term, which forces you to pay it off. A debt consolidation loan works the same way. Neither has an upfront fee like a balance transfer card does.

If you own a home, a home equity line of credit (HELOC) or home equity loan typically charges lower interest than a credit card, though it puts your home at risk if you cannot pay.

If you cannot pay the debt down quickly, negotiating directly with your creditor or working with a nonprofit credit counselor may be a better path than taking on new debt.

Frequently Asked Questions

Can I transfer a balance from a debit card or savings account?

No. Balance transfers only work between credit cards. You cannot transfer from a debit card, bank account, or loan. You can only move debt that is already on a credit card.

What if I miss a payment during the 0% period?

Missing a payment can end the promotional rate when ready. The issuer may charge you the regular interest rate on the entire balance, even the part that was supposed to be 0%. Check your card agreement for the exact terms, but assume that one late payment will cost you the promotional period.

Can I transfer a balance if I just opened the card?

Yes. Most issuers let you transfer a balance as soon as your account opens, as long as you do it within the promotional window (usually 60 days). You do not have to wait or make a payment first.

Does a balance transfer hurt my credit score?

A balance transfer temporarily lowers your score because of the hard inquiry and the new account. However, it can improve your score over time if it lowers your credit utilization ratio — the amount of credit you are using compared to your total available credit. Moving a $5,000 balance from a maxed-out card to a new card with a $10,000 limit lowers your utilization and helps your score recover.

What if I cannot pay off the balance before the 0% period ends?

Any remaining balance will be charged the regular interest rate. If you know you cannot pay it off, consider a personal loan or a second balance transfer card instead. A personal loan has a fixed term and interest rate, so you know exactly what you will pay. A second transfer card gives you more time, but costs another transfer fee.
