Should I Do a Balance Transfer? When 0% APR Saves You Money
A 0% balance transfer can save $1,500–$4,000 in interest on a typical credit card balance, but the 3–5% transfer fee, the requirement to clear the balance before the promo ends, and credit-score impact mean it is not always the right move. Here is when it pays off.

Step-by-step

Confirm the balance is large enough to matter
For balances under $2,000, the 3% transfer fee ($60) usually exceeds 6 months of interest at 22% APR (~$220). The math works for $2,000+ balances; below that, just pay it off aggressively from the existing card.

Find the longest 0% APR period you can qualify for
Top current offers in 2026: Citi Diamond Preferred and Wells Fargo Reflect at 21 months, Discover It at 18 months, Chase Slate Edge at 18 months. Length matters more than fee — saving 18 months of interest at 22% APR easily covers a 3–5% upfront fee.

Calculate your monthly payment to clear before promo ends
Take the transfer balance + transfer fee, divide by promo months. A $5,000 balance with a $150 fee on a 21-month 0% promo = $5,150 / 21 = $246/month minimum. If you cannot reliably hit this number, the promo expires, the rate reverts (often to 26%+), and you owe interest going forward on the remaining balance.

Confirm your credit score qualifies
670+ FICO is typical for the longer (18–21 month) 0% transfer cards. 740+ for the best terms. Soft-inquiry pre-qualification tools at most issuer sites tell you your odds without a credit pull.

Watch for the deferred-interest trap
Some 0% promos (often retail store cards) use "deferred interest" — if you do not clear the entire balance by the promo end, you owe ALL interest from day one retroactively. Real bank-issued balance-transfer cards usually use "waived interest," which only charges interest on the remaining balance going forward. Read carefully.

Move the balance, then close the door behind it
Once transferred, do not put new purchases on the new card (any new purchase typically accrues interest at standard APR even during the 0% promo). Use a different card or debit for spending. Treat the transfer card as a closed-loop payoff vehicle.
💡 Tips
- Apply for the new card BEFORE you tell your current issuer you plan to transfer. Otherwise the current issuer can lower your credit limit, hurting utilization the moment you transfer.
- You can usually transfer up to 90–95% of your new card's credit limit. Apply for a high enough limit that the transferred balance leaves headroom — high utilization on the new card hurts your score during payoff.
- Transfers between cards from the same issuer are not allowed (Chase to Chase, Citi to Citi). Plan transfers across issuer brands.
FAQ
Does a balance transfer hurt my credit score?
Short-term yes, by 5–15 points from the new-account hard pull and shortened average account age. Medium-term it usually helps because the new card adds to your total available credit, dropping overall utilization. Long-term, paid-off debt is a meaningful score positive.
Is a balance transfer fee tax deductible?
No. Personal credit card fees and interest are not deductible. The savings come from the math (lower interest paid), not from a tax angle.
Can I transfer the same balance multiple times?
Technically yes, but each transfer charges a new fee, and after 2–3 transfers most issuers stop approving new accounts for that pattern (it shows up as "balance shopping" on your credit profile). The play works best as a one-time tool.
What happens if I miss a payment on a 0% balance transfer card?
Most cards revoke the 0% promo immediately on the first missed payment, reverting to the standard APR (typically 22–28%) on the remaining balance. Some cards even charge retroactive interest. Set autopay for at least the minimum.
Should I close my old card after transferring?
No, keep it open with a zero balance. Closing reduces your total available credit, raising utilization and hurting your score. The only reason to close is if it has an annual fee greater than the score-impact value.
