Balance Transfer Calculator
A 0% balance transfer can pause your interest — but the fee and the intro deadline decide whether it's actually worth it. Enter your numbers to see your net savings.
Is a balance transfer worth it?
It comes down to two numbers: the one-time fee (usually 3–5% of the balance) versus the interest you'd otherwise pay. If you're carrying a few thousand dollars at 20%+ APR, you could pay hundreds or thousands in interest — so a one-time 3% fee often saves far more than it costs. The catch is the deadline: anything left when the 0% period ends starts accruing at the card's regular APR. Divide your balance by the intro months and pay at least that much so it reaches zero in time.
Frequently asked questions
Is a balance transfer worth it?
Usually yes when the interest you'd avoid exceeds the transfer fee and you can clear the balance before the intro rate ends.
How does the fee work?
It's 3–5% of the amount moved, added to your new balance up front. $6,000 at a 3% fee adds $180.
What if I don't pay it off in time?
The leftover balance accrues at the regular post-intro APR. Pay balance ÷ intro months each month to finish before the promo ends.
Does it hurt my credit?
A small temporary dip from the new account, but lower utilization often helps over time. Paying the balance down matters most.
