⚠️ Key rules for balance transfers: Always make at least the minimum payment on time — one late payment typically ends the 0% promo immediately. Don't use the new card for purchases (different APR applies). Aim to pay off the full balance before the promo period ends. Set a calendar reminder for when the promo expires.

Frequently Asked Questions
How does a balance transfer work? ▾
You apply for a new credit card with a 0% introductory APR offer. If approved, you transfer your existing balance to the new card and pay a transfer fee (typically 3-5%). For the promotional period (usually 12-21 months), no interest accrues — every dollar you pay goes directly to principal. After the promo ends, the remaining balance is subject to the regular APR. The goal is to pay off the balance before the promo expires.
What credit score do I need for a balance transfer card? ▾
Most 0% balance transfer cards require good to excellent credit — typically a FICO score of 670+ for standard offers and 720+ for the best offers with the longest 0% periods. Check your credit score before applying. Hard inquiries temporarily ding your score by a few points, so only apply if you're likely to be approved. Pre-qualification tools at Credit Karma and NerdWallet can check your odds without a hard pull.
What happens if I don't pay off the balance before the promo ends? ▾
The remaining balance becomes subject to the regular APR, which is often higher than your original card. Any accrued interest is NOT retroactive on a balance transfer card (unlike deferred interest store cards). You'll still save on interest for the months you had the 0% rate, but you should have a plan to pay off the full amount before expiration or transfer again if eligible.
