What happens when you move a balance to a new card

A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You request the transfer from the new card's issuer, they contact your old card company, and the new issuer pays off part or all of your old balance. You then owe that amount to the new card instead, at whatever rate and terms that card offers.

The process is not instantaneous. The new card company typically takes 5 to 21 days to complete the transfer after you request it. During that time, you still owe your old card company — do not stop paying them until the transfer clears and your old statement shows a zero balance. If you miss a payment on the old card while the transfer is pending, you can damage your credit score even though you are in the middle of moving the debt.

Balance transfers are useful only if the new card's interest rate is genuinely lower than what you are paying now, and only if you can pay down the balance before any promotional rate expires. If you transfer a balance and then carry it for years at a higher rate than you started with, you have made your situation worse.

Key Takeaways

  • A balance transfer moves your debt from one card to another; the new card issuer pays off your old balance, and you owe the new card instead.
  • The transfer takes 5 to 21 days to complete, and you must keep paying your old card during that time or risk a missed-payment mark on your credit report.
  • Most balance transfer cards offer a promotional rate (often 0% APR) for a limited period, usually 6 to 21 months depending on the card.
  • You pay a balance transfer fee, typically 3% to 5% of the amount transferred, charged to your new card immediately or added to your balance.
  • A balance transfer only saves you money if the new card's rate is lower than your current rate and you pay down the balance before the promotional period ends.

How the transfer request works and what the card company needs

You start by contacting the new card issuer — the company whose card you want to transfer the balance to. You can do this online through their website, by phone, or sometimes through their mobile app. You will need to provide the account number of the old card, the card issuer's name, and the amount you want to transfer.

The new card company will tell you immediately whether they can transfer that amount. They check your credit limit on the new card; you cannot transfer more than your available credit allows. If you have a $5,000 credit limit and already owe $2,000, you can transfer up to $3,000. Some issuers also set a separate cap on balance transfers — for example, they might limit you to 90% of your credit limit for transfers even if you have more room available.

Once you confirm the transfer amount, the new card company sends a payment to your old card company. This payment comes from your new card's credit line, so the transferred amount immediately appears as a balance on your new card. Your old card's balance drops by that amount (or to zero if you transferred the full balance). The old card remains open unless you close it yourself.

Balance transfer fees and how they are charged

Every balance transfer costs a fee. The fee is usually 3% to 5% of the amount you transfer, though some cards charge as little as 2% or as much as 5%. A few cards offer a 0% transfer fee for a limited time, but this is rare and usually only for new cardholders in their first 60 days.

The fee is charged to your new card immediately. If you transfer $3,000 at a 4% fee, you owe $120 in fees plus the $3,000 balance, for a total of $3,120 on your new card. Some issuers add the fee to your balance; others deduct it from your available credit. Either way, you pay it — it does not disappear.

This fee is why a balance transfer only makes sense if you are moving to a significantly lower rate. If you are paying 22% APR on your old card and moving to a card with a 0% promotional rate for 12 months, the fee is worth it because you will save far more in interest than you pay in fees. If you are moving from 18% to 16%, the fee might cost you more than the interest you save.

Promotional rates and what happens when they end

Most balance transfer cards offer a promotional period at a reduced rate, often 0% APR. This period typically lasts 6 to 21 months, depending on the card and the issuer's current offer. During the promotional period, you pay no interest on the transferred balance — only the principal you owe.

When the promotional period ends, the card's regular APR kicks in. This rate is usually between 15% and 29%, depending on your creditworthiness and the card. If you still owe a balance at that point, you will start paying interest at the new rate on whatever amount remains.

This is why timing matters. If you transfer $5,000 to a card with 0% APR for 12 months, you need to pay down that $5,000 (or close to it) within those 12 months. If you pay $400 per month, you will owe $200 when the promotional period ends, and you will then pay interest on that $200 at the card's regular rate. If you pay nothing, you will owe the full $5,000 at the higher rate — and interest will accrue on top of it.

How a balance transfer affects your credit score

A balance transfer can temporarily lower your credit score, usually by 5 to 10 points, because the new card company runs a hard inquiry on your credit report when you request the transfer. This inquiry shows up on your report and signals that you have recently sought new credit.

Your score may also drop because your credit utilization ratio changes. If you transfer $3,000 from an old card to a new card, your utilization on the old card goes down (good for your score) but your utilization on the new card goes up (bad for your score). The net effect depends on your total credit limits across all cards.

Over time, a balance transfer can improve your score if it helps you pay down debt faster. By moving to a lower rate, you can afford to pay more toward principal each month, which reduces your overall balance and lowers your utilization ratio. However, this only happens if you actually pay down the balance — simply moving it does not improve your score on its own.

When a balance transfer makes financial sense

A balance transfer saves you money only in specific situations. First, the new card's interest rate must be meaningfully lower than your current rate. Moving from 20% APR to 18% APR probably will not save enough to cover the transfer fee. Moving from 22% to 0% for 12 months usually will.

Second, you must have a realistic plan to pay down the balance before the promotional rate ends. If you cannot pay $400 per month on a $5,000 balance, do not transfer it to a 0% card for 12 months — you will owe the full amount at a higher rate when the promotion ends. Calculate how much you can actually pay each month, then check whether that amount will clear the balance in time.

Third, you should not use the balance transfer as an excuse to run up new debt on your old card. If you transfer $3,000 to a new card and then charge another $3,000 on the old card, you have not reduced your total debt — you have just moved part of it. The old card's new balance will still accrue interest at the old rate.

What to do during the transfer period and after

While the transfer is processing (5 to 21 days), continue making at least the minimum payment on your old card. Your old card company does not know the transfer is coming and will report a missed payment if you skip a month. A missed payment damages your credit score and can trigger a higher interest rate, even if the transfer eventually goes through.

Once the transfer completes, your old card's balance will drop. You can then decide whether to close the old card or leave it open. Closing it will reduce your available credit and may slightly lower your score. Leaving it open keeps your available credit high, which helps your utilization ratio, but it also tempts you to use it again. If you leave it open, do not charge anything new to it — focus all your payments on the new card's transferred balance.

On your new card, pay as much as you can afford each month, especially during the promotional period. Any amount you pay during the 0% period goes entirely toward principal, with no interest. After the promotional period ends, your payments will include interest, so paying aggressively now saves you money later.

Frequently Asked Questions

Can I transfer a balance if I have bad credit?

Balance transfer cards typically require fair to good credit (a score of 650 or higher). If your credit is lower, you may not be approved for a balance transfer card, or you may be approved with a higher interest rate and a lower credit limit. Some cards offer balance transfers to people with lower scores, but the promotional rate may be shorter or the regular APR higher.

What if my old card company refuses the balance transfer payment?

This is extremely rare. Credit card companies routinely accept payments from other issuers. If there is a problem, the new card company will contact you and let you know. You can also call your old card company directly to confirm they received the payment and to ask what your new balance is.

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

No. You cannot transfer a balance from a card to itself. You must transfer to a different card from a different issuer. Some people open a new card with the same issuer and try to transfer between them; most issuers block this as well.

What happens if I miss a payment on the new card during the promotional period?

Missing a payment can end your promotional rate immediately. The card company may apply their regular APR to your entire balance, even though you are still in the promotional period. You will also face a late fee and a mark on your credit report. Set up automatic payments or calendar reminders to avoid this.

Can I do another balance transfer if I still owe money on the first one?

Yes, you can transfer a balance from one card to another even if you are still paying off a previous transfer. However, each transfer costs a fee and requires a hard inquiry on your credit. Doing multiple transfers in a short time can damage your credit score and may make it harder to get approved for new cards.
