What happens when you transfer a balance
A balance transfer moves debt you owe on one credit card to a different card, usually one with a lower interest rate. You do not pay off the first card yourself — the new card's issuer pays it on your behalf, and you then owe that new issuer instead. The debt moves, but you still owe the money.
Balance transfers typically come with a temporary lower rate, often 0% for a set period (commonly 6 to 21 months, depending on the card and the offer). After that period ends, the regular interest rate kicks in. Most cards charge a balance transfer fee — usually 3% to 5% of the amount you move — added to your new balance on day one.
The math matters: if you transfer $5,000 at a 4% fee, you owe $5,200 immediately, plus whatever interest accrues after the promotional period. A balance transfer only saves you money if the interest you avoid during the 0% period exceeds the fee you pay upfront.
Key Takeaways
- Balance transfers move your debt to a new card with a lower rate, but you pay a fee (usually 3% to 5%) upfront and owe the full amount to the new issuer.
- The 0% promotional period typically lasts 6 to 21 months; after it ends, the regular interest rate applies to any remaining balance.
- You must request the transfer from the new card's issuer, who contacts your old card company to arrange payment.
- Paying down the balance during the promotional period is the only way a transfer actually saves you money.
- Your credit score may dip temporarily when you open a new card and when the new issuer checks your credit, but it usually recovers within a few months.
How to start a balance transfer
Contact the credit card company whose card you want to transfer the balance to — the new issuer, not your current one. You can do this by phone, online through their website, or by mail. Tell them you want to transfer a balance and provide the account number of the card you're transferring from, the amount you want to move, and the cardholder name on that account.
The new issuer will then contact your old card company to arrange the payment. This usually takes 5 to 14 business days. During this time, keep making minimum payments on your old card to avoid late fees; the transfer does not stop interest from accruing on the old card until the payment actually clears.
Once the transfer completes, your old card's balance drops (or goes to zero if you transferred everything), and the new card's balance increases by the amount transferred plus the fee. You now owe the new issuer. Your old card remains open unless you close it, which you can do anytime after the transfer settles.
When a balance transfer makes financial sense
A transfer saves money only if you pay down the balance during the 0% period. If you transfer $5,000 at a 4% fee ($200) and pay it off in 12 months while the rate is 0%, you save the interest you would have paid on the old card. If your old card charged 18% APR, you would have paid roughly $900 in interest over a year — so the $200 fee is worth it.
If you do not pay off the balance before the promotional period ends, the regular interest rate applies to whatever remains. Transferring $5,000, paying $1,000, and leaving $4,000 for after the 0% period means you pay interest on that $4,000 at the new card's standard rate, which may be as high as 20% or more. In that case, you may have been better off keeping the debt on the original card.
Balance transfers work best when you have a concrete plan to pay down the debt within the promotional window and when your old card's interest rate is significantly higher than the new card's regular rate. If you're just moving debt around without reducing it, you're not solving the underlying problem.
Balance transfer fees and what they cost
The fee is charged once, when the transfer completes, and added to your new balance. A 3% fee on a $10,000 transfer costs $300. A 5% fee on the same amount costs $500. Some cards offer 0% balance transfer fees for a limited time (usually the first 60 days after opening the account), but this is rare and usually paired with a shorter promotional interest period.
The fee is not optional — you cannot avoid it by negotiating or by paying it separately. It is built into the transfer process. However, you can reduce the total cost by transferring only the amount you actually need to move. If you have $8,000 on an old card at 20% and $2,000 on a new card at 0%, transferring only the $8,000 means you pay a fee on $8,000, not $10,000.
How balance transfers affect your credit score
Opening a new card triggers a hard inquiry into your credit, which typically lowers your score by a few points. This dip is temporary and usually recovers within a few months. At the same time, the new card adds to your total available credit, which can improve your score if it lowers your overall credit utilization ratio (the percentage of your total credit limit you're using).
When the transfer completes, your old card's balance drops, which also improves your utilization ratio. However, if you close the old card after the transfer, you lose that available credit, which can hurt your score. Most people leave the old card open (but unused) to keep the credit line active.
The net effect on your score depends on your overall credit profile. If you have good credit, the dip is usually small and temporary. If your credit is already low, the hard inquiry and new account may have a larger impact. Either way, the effect fades over time, especially if you make on-time payments on the new card.
What to do if you cannot transfer the full balance
Balance transfer limits are set by the card issuer and depend on your credit score, income, and credit history. You might be approved for a $5,000 transfer when you owe $8,000. In that case, you can transfer $5,000 to the new card and leave $3,000 on the old card.
You then have two debts: the $5,000 on the new card at 0% (for the promotional period) and the $3,000 on the old card at its original rate. You can pay both simultaneously or focus on paying down the 0% balance first, then tackle the old card once the promotional period ends. Some people prioritize the old card to reduce the amount of interest accruing there.
If the transfer limit is too low to be useful, you can reapply with a different card issuer or wait a few months and reapply with the same issuer after your credit profile improves. Applying multiple times in a short period can lower your score further, so space out applications if possible.
Alternatives if a balance transfer is not an option
If you do not may have access to for a balance transfer card or the limit is too low, other options exist. A personal loan from a bank or credit union may offer a lower interest rate than your credit card, and you pay it back on a fixed schedule. A debt consolidation loan works similarly but is designed specifically for combining multiple debts into one payment.
Some credit card issuers offer hardship programs that lower your interest rate or pause payments if you contact them and explain your situation. This does not move the debt, but it can reduce what you owe over time. You can also negotiate directly with your card issuer to ask for a lower rate — they sometimes agree, especially if you have been a long-term customer with a good payment history.
If you're struggling with multiple debts, a nonprofit credit counselor can review your situation and help you decide whether a balance transfer, consolidation loan, or payment plan makes the most sense. The National Foundation for Credit Counseling (NFCC) offers free or low-cost consultations.
Frequently Asked Questions
Can I transfer a balance to a card from the same bank?
Most banks do not allow you to transfer a balance between their own cards. You typically must transfer to a card from a different issuer. Check the specific card's terms, as some issuers have exceptions, but this is uncommon.
What happens to my old card after the transfer?
The old card remains open with a zero or reduced balance. You can close it anytime, but leaving it open preserves your available credit and can help your credit score. If you close it, make sure the balance is fully paid first.
Can I make new purchases on the card I'm transferring to?
Yes, but new purchases usually have a different interest rate than the transferred balance. The 0% promotional rate typically applies only to the transferred balance, not to new charges. Check your card's terms to confirm.
What if I cannot pay off the balance before the 0% period ends?
The regular interest rate applies to whatever balance remains. If you owe $2,000 when the promotional period ends and the card's standard rate is 19%, you'll start paying interest on that $2,000. You can still pay it down, but interest will accrue going forward.
How long does a balance transfer take?
Most transfers complete within 5 to 14 business days after you request them. Some issuers are faster; others take longer. Contact your new card issuer to confirm the timeline and track the status of your transfer.
