Balance Transfer Calculator

Find out whether moving a credit card balance to a 0% intro APR card is worth the transfer fee. Enter your balance, your current APR, and what you can pay each month, then the new card’s fee, intro rate, and how long the intro period lasts.

The calculator compares total interest and fees on both cards, shows how much you’ll still owe when the intro rate ends, and tells you the monthly payment that would clear the balance before it does.

Frequently Asked Questions

Is a balance transfer worth it?

Usually, if you can pay down most of the balance during the intro period. Moving $6,000 from a 24% card to an 18-month 0% card with a 3% fee and paying $300 a month costs $180 in fees and about $30 of interest, versus roughly $1,739 of interest staying put.

How much is a balance transfer fee?

Typically 3% to 5% of the amount transferred, added to your new balance. A few cards offer no-fee transfers, often with shorter intro periods.

What happens when the 0% APR ends?

Any remaining balance starts accruing interest at the card’s regular APR. To avoid it, divide the transferred balance plus fee by the number of intro months and pay at least that each month.

Can I lose the intro rate?

Yes. Paying late can end the promotional rate early. Many cards also apply the regular APR to new purchases, so avoid using the card for spending while you pay off the transfer.
