Is a 0% Balance Transfer Worth It?

A promotional rate can lower interest costs, but the transfer fee and payoff deadline matter. Use this checklist before moving a balance.

A 0% balance transfer is worth it when the transfer fee is clearly smaller than the interest you’d otherwise pay, and when you can pay off most or all of the balance before the promotion ends. If you can’t make meaningful payments during the promo period, it mostly just moves the problem to a new card.

Run the numbers with your own balance

Here’s a typical example. You owe $6,000 on a card charging about 22%, which is roughly the average rate the Federal Reserve reported for accounts paying interest in mid-2026. You find a card offering 0% for 15 months with a 3% transfer fee.

Transfer: the fee is $180, so you owe $6,180. Dividing by 15 months gives a payment of $412. Pay that every month and the balance is gone before the promotion ends. Total cost: $180.
Stay put: paying the same $412 a month on the old card takes about 18 months and costs a bit over $1,000 in interest.

Here the transfer saves around $850. But change one thing, say you can only afford $200 a month, and the picture shifts. After 15 months you’d still owe about $3,200, which then starts collecting interest at the new card’s regular rate. You’d still come out ahead of staying put, but not by as much, and you’d be relying on that regular rate being reasonable.

Transfer fees typically run 3% to 5% of the amount moved. Promotional periods commonly last anywhere from 6 to 21 months.

Read the offer carefully

Before applying, find:

the transfer fee, and whether there’s a minimum dollar amount
how long the 0% rate lasts, and exactly when it ends
the rate that applies afterward
whether the transfer has to be completed within a certain window, often the first 60 days or so
whether the promo applies to purchases too, or only to transfers

Also check the credit limit you’re approved for. If you’re approved for $5,000, you can’t move a $6,000 balance plus the fee. You’ll have to keep paying the remainder on the old card.

Most issuers won’t let you transfer a balance between two of their own cards, so the new card usually needs to come from a different bank.

Keep paying the old card until the transfer posts

Transfers can take a week or two, sometimes longer. Until the old card shows the balance paid, keep making at least the minimum payment there. A missed payment during the switch can mean a late fee and a mark on your credit report.

Don’t shop on the transfer card

This is the trap that catches the most people. If you carry a promotional transfer balance and also use the card for purchases, those purchases may collect interest from day one, because you’re no longer paying the whole balance each month and so lose the grace period. How Credit Card Grace Periods Work explains why. Put everyday spending on a different card, or on debit.

Pay on time, too. A late payment can cost you the promotional rate, and once you’re more than 60 days late the issuer can apply a penalty rate to the balance.

When it makes sense

A transfer tends to work when the fee is small next to the interest saved, the monthly payment needed to clear it fits your budget, and you’ve stopped adding to the debt. It works less well if you’re likely to run the old card back up or if the payment is out of reach. In that case, a structured plan from How to Get Out of Debt or a nonprofit credit counselor may be the better first step.
