Balance transfer cards offer a window — typically 12-21 months at 0% APR — to pay down high-interest credit card debt without compounding interest eating your progress. The math works when you can pay the transferred balance within the intro window. Here are the 4 cards worth shopping for balance transfers.
21 months at 0% APR on balance transfers — the longest intro window available in 2026. Balance transfer fee 3% or $5 minimum. Strong pick for larger balances that need the full runway to pay off.
Up to 21 months 0% APR (15 months base + 3-month extension for on-time payment + 3 more with qualifying activity). $0 AF. Fee 3% or $5. Solid backup if Citi doesn't approve.
18 months 0% intro APR on balance transfers. After intro, earns 2% flat cash back on all purchases — so the card stays useful post-payoff. Transfer fee 3% or $5.
15 months 0% intro APR. Shorter window but Discover is the most accessible issuer on this list for applicants at fair-credit scores. First-year Cashback Match adds value post-intro.
You apply for the new card, request a balance transfer from your old card(s) to the new card, and the new issuer pays off the old balance. You then owe the new card. The old card balance is gone — paid by the new issuer. The 0% intro APR applies to the transferred balance (and sometimes purchases; check the terms). You pay off the transferred balance within the intro window to avoid interest.
Typically 3% of the transferred amount (minimum $5). On a $5,000 transfer, that's $150 upfront. If your current card charges 24% APR, 12 months of interest on $5,000 = $1,200. The $150 transfer fee is a clear win. Run the math on your specific balance and current APR — the fee is almost always worth it when the current APR is above 15%.
The remaining balance starts accruing interest at the card's regular purchase APR — typically 19-29% depending on your credit profile. Unlike deferred-interest products, there's no retroactive interest on what you already paid off. Only the remaining balance starts accruing. Set a payoff plan before you transfer.
