Quick answer
A balance transfer moves debt from one credit card to another, usually to take advantage of a 0% or low introductory APR. You typically pay a one-time transfer fee, often a percentage of the amount moved. It saves money when the fee is lower than the interest you would otherwise pay and you can pay off the balance before the promotional rate ends.
Key takeaways
- Divide the transferred balance plus fee by the number of promo months to find your required monthly payment.
- Most issuers don’t allow transfers between their own cards.
- Intro offers often require transfers within a set window after account opening.
- Late payments can end a promotional rate on some cards.

Estimated time: 14 days
- Add up your balances and rates. List the card balances you want to move and their current APRs.
- Compare offers. Compare intro APR length, transfer fee, regular APR and the transfer window on cards you are likely to qualify for.
- Calculate savings and the required payment. Compare the transfer fee with the interest you would pay otherwise, then divide the new balance by the promo months.
- Apply and request the transfer. Apply for the new card and submit the transfer with the old account numbers and amounts.
- Keep paying the old card until it posts. Continue minimum payments on the old card until the transfer is complete.
- Pay off the balance before the promotion ends. Set up automatic payments large enough to clear the balance within the promotional period.
If you are paying high interest on a credit card balance, a balance transfer can pause the interest for months and let every payment go toward the debt itself. It is one of the most effective tools for getting out of credit card debt — but only if you understand the fee, the timeline and the fine print.
How a balance transfer works
- You open a new card (or use an existing one) that offers a promotional APR on transferred balances — often 0% for a set number of months.
- You ask the new issuer to pay off some or all of your old card’s balance.
- That amount, plus a balance transfer fee, becomes a balance on the new card.
- You pay down the new balance during the promotional period, with little or no interest.
- When the promotion ends, any remaining balance begins accruing interest at the card’s regular APR.
The balance transfer fee
Most cards charge a fee on each transfer, commonly a percentage of the amount moved, sometimes with a minimum dollar amount. The fee is usually added to your new balance.
On a $6,000 transfer with a 3% fee, you would pay $180; with a 5% fee, $300.
Does it save money? The math
Suppose you owe $6,000 at 24% APR and can pay about $375 a month.
| Option | Time to pay off | Interest + fees |
|---|---|---|
| Keep it on the current card | about 20 months | about $1,300 |
| Transfer to a 0% card for 18 months with a 3% fee | 17 months (payments of about $364) | $180 |
In this example, the transfer saves about $1,100. Try your own numbers in the credit card payoff calculator.
Find your required monthly payment
(Transferred balance + fee) ÷ number of promotional months = monthly payment needed
For $6,000 plus a $180 fee over 18 months: $6,180 ÷ 18 ≈ $343 per month. Set up autopay for at least that amount.
What to compare between cards
| Feature | Why it matters |
|---|---|
| Length of intro APR period | More months means a lower required payment |
| Balance transfer fee | Eats into your savings |
| Transfer window | Many offers apply only to transfers made within a set period after opening |
| Regular APR after the promotion | What you pay on any remaining balance |
| Credit limit | Determines how much you can transfer |
| Purchase APR | Whether new purchases also get a 0% rate |
| Annual fee | Adds to your cost |

Rules and pitfalls
- You usually can’t transfer between cards from the same issuer.
- Your new credit limit may be lower than your balance. You may be able to transfer only part of it.
- Keep paying the old card until the transfer is complete to avoid a late payment.
- Avoid new purchases on the transfer card unless purchases also have a 0% rate. Minimum payments may be applied to the lower-rate balance, though amounts above the minimum generally go to the highest-rate balance first under federal rules.
- Don’t miss a payment. Some cards can end the promotional rate or apply a penalty APR after a late payment.
- Watch for deferred interest on some store cards — unlike a true 0% APR, it can charge all the interest from the start if the balance is not paid in full by the deadline.
Who a balance transfer is right for
A balance transfer tends to work best when you:
- Have good enough credit to qualify for a strong offer
- Can afford a monthly payment large enough to clear the balance within the promotion
- Have stopped adding new card debt
If your credit doesn’t qualify you for a long 0% period, a fixed-rate debt consolidation loan or a nonprofit debt management plan may be a better fit.
Effect on your credit
Opening a new card causes a hard inquiry and lowers the average age of your accounts, which may dip your score slightly. Over time, the added credit limit can lower your overall utilization, and on-time payments build positive history. Keep the old card open (with a zero balance) if it has no annual fee.
The bottom line
A balance transfer is a powerful, temporary tool: it buys you interest-free time to pay down debt. Make sure the fee is worth it, calculate the payment needed to finish before the promotion ends, automate it and avoid new charges. For a full payoff plan, read how to pay off credit card debt.
