What Is a Balance Transfer?

A balance transfer moves existing credit card debt from one or more high-interest cards to a new card with a lower rate, typically a promotional 0% APR period lasting 12-21 months. The goal is to eliminate or reduce interest charges so more of your payments go toward paying down the actual debt. Most balance transfer cards charge a fee of 3-5% of the transferred amount.

How to Use This Calculator

Enter your current balance, your current card's APR, the balance transfer fee percentage, the promotional APR (usually 0%), the promotional period in months, and the regular APR after the promotional period ends. The calculator shows your total interest saved, the break-even point where savings exceed the transfer fee, and the monthly payment needed to pay off the balance before the promotional rate expires.

Transfer Fee = Balance x Fee Rate
Monthly Payment to Pay Off = (Balance + Fee) / Promo Months
Interest Saved = Current Interest - Transfer Fee

When a Balance Transfer Makes Sense

A balance transfer is worthwhile when the interest savings exceed the transfer fee and you can realistically pay off the balance during the promotional period. If you have $8,000 at 22% APR and transfer to a card with 0% for 18 months and a 3% fee ($240), you save roughly $2,400 in interest over 18 months minus the $240 fee. That is $2,160 in net savings. The key is committing to paying $457/month to eliminate the balance before the promo ends.

Balance Transfer FAQ

What happens when the promotional period ends?
The remaining balance begins accruing interest at the card's regular APR, which is typically 18-26%. Any balance left after the promotional period can quickly become expensive. This is why it is critical to calculate the monthly payment needed to pay off the full balance during the promotional window and commit to that payment.
Does a balance transfer hurt my credit score?
Opening a new card creates a hard inquiry (small temporary dip) and lowers your average account age. However, it also increases your total available credit, which can lower your credit utilization ratio and improve your score. The net effect is often neutral or slightly positive if you do not close the old card and do not add new debt.
Can I transfer balances between cards from the same bank?
Usually not. Most issuers do not allow balance transfers between their own cards. You need to transfer to a card from a different issuer. Check the terms of the balance transfer offer before applying.
