- You open a new card (or use an existing one) offering a balance transfer promotion.
- You request a transfer of your existing balance(s) from other cards to the new one.
- The new issuer pays off the old balance, and the debt now sits on the new card, usually at 0% or a low promotional APR.
- You pay off the balance during the promotional period before the regular APR kicks in.
What a Balance Transfer Costs
- Transfer fee: Typically 3% to 5% of the amount transferred, charged upfront.
- Regular APR after the intro period: Whatever balance remains starts accruing interest at the card’s standard rate.
- Possible loss of the promo rate: Missing a payment can sometimes end the promotional APR early, depending on the card’s terms.
Is a Balance Transfer Worth It?
Run the math: compare the transfer fee against the interest you’d pay by not transferring. For example, transferring a $5,000 balance at a 3% fee costs $150 upfront, but if that balance is currently accruing interest at 24% APR, transferring to 0% APR can save hundreds of dollars over the promotional period, even after the fee.
How to Use a Balance Transfer Card Wisely
- Have a real plan to pay off the balance before the promotional period ends.
- Divide the balance by the number of promotional months to know your target monthly payment.
- Avoid putting new purchases on the card unless they also qualify for the promotional rate — some cards apply the intro rate only to transfers, not new spending.
- Don’t close your old card immediately, since that can affect your utilization and credit history length. See secured vs. unsecured credit cards for other card fundamentals.
What Happens If You Don’t Pay It Off in Time?
Whatever balance remains starts accruing interest at the card’s regular APR, which can be high. Some cards also apply deferred interest retroactively to the entire original balance if it’s not paid off by the deadline, so read the terms carefully before transferring.
Frequently Asked Questions
Does a balance transfer hurt your credit score?
Opening a new card involves a hard inquiry, which can cause a small, temporary dip. Paying down debt through the transfer generally helps your score over time by lowering utilization.
Can I transfer a balance between cards from the same bank?
Usually not. Most issuers don’t allow transfers between their own cards, so you’ll typically need a card from a different bank.
Is 0% APR really free?
The rate itself is free during the promotional window, but the transfer fee still applies, and any balance left after the promo ends is charged the regular APR.
How many times can I do a balance transfer?
There’s no fixed legal limit, but each new card application creates a hard inquiry, and repeatedly transferring debt without paying it down doesn’t address the underlying spending.
