The Short Answer
A balance transfer moves debt from one credit card to another, usually to take advantage of a promotional interest rate — often 0% for a set period. Instead of paying down a balance at a high ongoing APR, you shift it to a card offering little or no interest for, say, 12 to 21 months, which lets more of each payment go toward the actual debt instead of interest charges.
In short, a balance transfer is a way to buy yourself a temporary break from interest while you pay down what you owe.
How a Balance Transfer Works
- Apply for a card with a balance transfer offer, or check if a card you already have extends one.
- Request the transfer, specifying which balance(s) and how much to move.
- The new issuer pays off the old card directly, up to your approved limit.
- You now owe the new card, ideally at 0% or a low promotional APR for a set window.
Balance Transfer Fees and Promotional Periods
A balance transfer isn’t free, and the offer isn’t permanent:
- Transfer fee. Typically 3% to 5% of the amount moved, charged upfront and added to your new balance.
- Promotional period. Commonly 12 to 21 months at 0% or a low rate.
- After the promo ends, any remaining balance starts accruing interest at the card’s regular ongoing APR.
A Simple Example
Example: You carry a $6,000 balance at 24% APR. You transfer it to a card offering 0% for 18 months, with a 3% transfer fee — $180, added to your new balance of $6,180. If you pay about $345 a month, you’d clear it within the promotional window, paying only that $180 fee instead of the roughly $1,300-plus in interest you’d have paid staying on the 24% card over the same period.
Is a Balance Transfer a Good Idea?
- Have a payoff plan. It works best when you can clear the balance before the promo rate ends.
- Do the math on the fee. Confirm the transfer fee is smaller than the interest you’d otherwise pay.
- Don’t run up the old card again. Moving debt only helps if you don’t recreate it on the card you just paid off.
- Watch the deadline. Some cards apply retroactive interest to the whole balance if it isn’t paid off by the time the promo ends.
The Bottom Line
A balance transfer moves debt to a card with a lower, often 0%, promotional rate so more of your payment reduces the actual balance instead of vanishing into interest. It typically costs a one-time fee of 3% to 5% of the amount moved, and the benefit only holds if you pay it off before the promotional period ends. Used with a real payoff plan, it can save meaningful money; used without one, the debt simply moves and the clock keeps running.
Frequently Asked Questions
What is a balance transfer in simple terms?
It’s moving a credit card balance to a different card, usually one with a lower promotional interest rate, so more of your payment goes toward the debt instead of interest.
How much does a balance transfer cost?
Most cards charge a transfer fee of 3% to 5% of the amount you move, added to your new balance upfront. Weigh that fee against the interest you’d save.
What happens if I don’t pay off the balance before the promo ends?
Whatever is left starts accruing interest at the card’s regular ongoing APR. Some cards may also charge deferred interest back to the transfer date, so check your card’s specific terms.
Does a balance transfer hurt my credit score?
Opening a new card involves a hard inquiry and can briefly dip your score. Over time, though, lower balances and on-time payments on the new card typically help your score more than the initial dip hurts it.
Can I transfer a balance between cards from the same bank?
Usually not. Most issuers won’t let you transfer a balance from one of their own cards to another of their cards — the offer is meant to win business from a competitor’s card.
Is a balance transfer better than a personal loan for paying off debt?
It depends on the numbers. A balance transfer can beat a personal loan if you can realistically pay it off within the promo window; if you need longer, a fixed-rate personal loan may end up cheaper and more predictable.
