What happens when you move a balance to a new card

A balance transfer moves debt you owe on one credit card to a different credit card, usually one with a lower interest rate. You request the transfer from the new card's issuer, they pay off your old card's balance directly, and you then owe that amount to the new card instead. The goal is to reduce the interest you pay while you work down the debt.

The new card issuer does not pay your old card in full and hand you the difference. They pay the exact balance you ask them to transfer — nothing more — and that amount becomes your new debt with them. You remain responsible for any remaining balance on the original card if you do not transfer all of it.

Most balance transfers happen between cards from different banks, but some issuers allow transfers between their own products. The process typically takes 5 to 14 business days from request to completion.

Key Takeaways

  • The new card issuer pays your old card directly, so you do not handle the money yourself.
  • A balance transfer fee — usually 3% to 5% of the amount transferred — is added to your new card balance on day one.
  • The low introductory rate applies only to the transferred balance, not to new purchases you make on that card.
  • If you miss a payment during the promotional period, the issuer can end the offer and charge you the regular interest rate retroactively.
  • The transfer does not close your old card, so your credit report will still show that account and its available credit.

The balance transfer fee and how it affects your total cost

When you transfer a balance, the new card issuer charges a fee upfront. This fee is typically 3% to 5% of the amount transferred, though some cards charge as little as 2% or as much as 5%. The fee is added to your new balance immediately, so if you transfer $5,000 with a 4% fee, you now owe $5,200 on the new card.

This fee is a real cost, not something you can avoid by paying faster. Even if you pay off the transferred balance in full during the promotional period, you still owe the fee. The benefit of a balance transfer comes from the interest you save during the low-rate period, not from avoiding the fee itself.

To know whether a transfer makes sense, compare the fee cost against the interest you would pay on your current card over the same timeframe. If your current card charges 22% interest and the new card offers 0% for 12 months with a 4% fee, you save money unless you need more than 18 months to pay off the debt. Many card issuers publish a "savings calculator" on their website that does this math for you.

Introductory rates and what happens when they end

The new card offers a promotional interest rate — often 0% — for a set period, usually 6 to 21 months depending on the card and the issuer's current offers. This rate applies only to the balance you transferred, not to new purchases or cash advances. If you make a new purchase on the card, that purchase typically starts accruing interest at the card's regular rate immediately.

When the promotional period ends, the regular interest rate kicks in for any remaining balance. If you still owe $3,000 of the transferred balance after 12 months of 0%, you will start paying interest on that $3,000 at the card's standard rate — often 18% to 24% — on month 13. The issuer will tell you the regular rate before you complete the transfer.

If you miss a payment during the promotional period, most issuers will end the offer and charge you the regular rate on the entire transferred balance, sometimes retroactively to the transfer date. This is called a "penalty APR" or loss of promotional status. Missing even one payment can cost you hundreds of dollars in interest.

How to request a balance transfer

Start by choosing a new card with a promotional rate that fits your payoff timeline. Check the card's terms to confirm the fee amount, the length of the promotional period, and the regular interest rate that applies after. You can find this information on the issuer's website or by calling their customer service line.

Once you have opened the new card, log into your account online or call the issuer's balance transfer department. You will need the account number of the card you want to pay off, the exact balance you want to transfer, and the name and address of the old card's issuer. Some issuers let you request the transfer immediately after opening the account; others require you to wait a few days.

The issuer will confirm the transfer amount, the fee, and the promotional rate before processing. The transfer typically completes within 5 to 14 business days. During this time, keep making at least the minimum payment on your old card to avoid a late fee or damage to your credit score. Once the transfer posts, the old card's balance will drop by the transferred amount.

What to do with your old card after the transfer

Do not close the old card immediately after the transfer completes. Closing it can lower your credit score because it reduces your total available credit and may shorten your average account age. Instead, leave the account open with a zero balance.

If the old card had a remaining balance that you did not transfer, you still owe that amount and must make payments on it. Some people transfer only part of their balance to keep the old card's balance manageable while they work on paying down the transferred amount on the new card.

You can close the old card after the promotional period on the new card ends, or after you have paid off the transferred balance — whichever comes first. This timing minimizes the impact on your credit score. If the old card charges an annual fee, closing it sooner may make sense to avoid that cost.

When a balance transfer makes financial sense

A balance transfer saves you money only if the interest you avoid during the promotional period exceeds the transfer fee and any other costs. If you currently owe $4,000 at 20% interest and you can transfer it to a card with 0% for 12 months and a 3% fee, you pay $120 in fees but save roughly $400 in interest — a net savings of $280.

The math breaks down if you cannot pay off the balance before the promotional period ends. If you transfer $4,000 with a 3% fee and 0% for 12 months, but you only pay $200 per month, you will still owe $1,600 when month 13 arrives. That $1,600 will then accrue interest at the regular rate, potentially erasing your savings.

A balance transfer also makes sense if you are consolidating multiple cards. Instead of juggling payments across three cards at 18%, 21%, and 23%, you move all three balances to one card at 0% for 12 months. This simplifies your payment and gives you a clear deadline to work toward.

Balance transfers and your credit score

Opening a new card for a balance transfer causes a small, temporary dip in your credit score. The issuer performs a hard inquiry into your credit report, which typically lowers your score by a few points. This dip usually recovers within a few months.

Your credit utilization — the percentage of your available credit that you are using — may also change. If you transfer $5,000 from a card with a $10,000 limit to a new card with a $15,000 limit, your utilization on the old card drops from 50% to 0%, which helps your score. Your utilization on the new card starts at 33%, which is neutral to slightly positive.

Over time, a successful balance transfer can improve your score because you are paying down debt and demonstrating that you can manage credit responsibly. The key is making all payments on time and not running up new balances on either card.

Frequently Asked Questions

Can I transfer a balance from one card to the same issuer's different card?

Some issuers allow transfers between their own cards, but many do not. Check the specific card's terms or call the issuer before opening a new account. Even when allowed, the fee and promotional rate apply the same way as a transfer between different issuers.

What if I cannot pay off the balance before the promotional rate ends?

You will owe the regular interest rate on any remaining balance. If the regular rate is high, you may want to request another balance transfer to a different card before the first promotional period ends. This requires opening another new account and paying another transfer fee, so calculate whether the savings justify the cost.

Does a balance transfer hurt my credit score?

Opening a new card causes a small temporary dip from the hard inquiry. However, the transfer itself — moving debt from one card to another — does not directly harm your score. Your score may improve over time as you pay down the transferred balance and lower your overall credit utilization.

Can I transfer a balance if I am behind on payments?

Most issuers will not approve a balance transfer if your account is currently delinquent. You typically need to be current on all payments before requesting a transfer. If you are behind, contact your current issuer about a hardship program or payment plan first.

What happens to the old card's rewards or benefits?

Transferring a balance does not affect the old card's rewards program or other benefits. You can still earn rewards on new purchases made on that card. However, the promotional rate on the new card usually does not apply to new purchases, so rewards earned on the old card may be more valuable during the promotional period.
