Intro APR on purchases vs. balance transfers: not the same offer

Issuers advertise both offers under the same "0% intro APR" headline, but they're independently configured. A card might pair 15 months of 0% on purchases with 12 months of 0% on balance transfers — or vice versa — and a few cards offer 0% on only one of the two. Always read the cardholder agreement's two-line breakdown before you apply. If you plan to finance a $4,000 furniture purchase, you want a long purchases intro. If you're moving an existing balance, you want a long balance transfers intro and a low transfer fee. The Wells Fargo Reflect and Discover it Cash Back are notable in our table because they cover both. The Chase Freedom Unlimited and the Capital One Savor in this table cover purchases primarily.

What "deferred interest" is — and why it isn't the same as 0% APR

Retailer-issued financing — the "0% for 24 months" furniture-store, jewelry-store and dental-office cards — is structurally different from a real 0% intro APR credit card. A real 0% intro APR card charges interest going forward only, on whatever balance remains after the intro window. A deferred-interest retail card calculates interest the entire time, silently, at the regular APR. Pay the full balance off before the deadline and the calculated interest is waived. Have one dollar remaining and the issuer back-charges every penny from the original purchase date — sometimes adding $800 to $1,200 to a balance you thought was almost gone. Look for "deferred interest" or "no interest if paid in full by" in the offer terms. None of the cards in our partner table use deferred-interest structures. We are not a card issuer.

Stacking 0% intros across cards (and what it does to your score)

Some users open a second 0% intro card before the first one's window closes — effectively rolling a remaining balance forward at zero interest. The math can work, but it has costs. Each new card application is a hard inquiry (5 to 10 points off your FICO, fades within a year), and the new account drops your average account age. More importantly, your total credit utilization is what FICO weights heavily, and stacked balances on multiple cards (even at 0%) can keep your reported utilization high if you're slow to pay down. The stack-then-pay-aggressively strategy works for disciplined users with stable income. The stack-then-keep-spending pattern is how people end up with five maxed-out cards and an unrecoverable score.

What happens at month 13 (or 16, or 22)

The day after your intro window closes, any remaining balance starts accruing at the card's regular APR — currently 17.49% to 28.49% across our partner network. There's no second chance, no grace period, and most issuers send a single email reminder roughly 60 days before the cliff. Set a calendar alert with the exact remaining balance and a payoff plan three months before the expiration date. If the math says you won't clear it in time, line up either a balance transfer card from a different issuer or a personal loan to consolidate, and time the move so the funds arrive before the regular APR snaps on. Don't wait until month 22 to start planning month 23.
