This is independent, informational comparison and not financial advice. A 0% intro period only helps if you have a clear payoff plan before it ends, because the regular APR afterward is high and applies to any remaining balance.

Pay close attention to whether the 0% offer applies to purchases, balance transfers, or both, and to the balance transfer fee. All figures here can change, so verify the current intro length, fees, and regular APR at the issuer before applying.

Wells Fargo Reflect: longest intro window (21 months)

The Wells Fargo Reflect offers the longest intro period of these three: 0% for 21 months on both purchases and qualifying balance transfers (transfers must generally be made within 120 days of opening). It has a $0 annual fee and no rewards, since it is built purely for the intro period.

After the intro window, the regular APR is roughly 17.49%–28.24% variable, and the balance transfer fee is 5%. If you need the most time to pay down either a purchase or a transferred balance, Reflect's 21 months is the standout, but confirm the transfer deadline, fee, and APR with Wells Fargo.

Citi Double Cash: 18 months on balance transfers only

The Citi Double Cash offers 0% for 18 months, but on balance transfers only, not on new purchases. That is a crucial distinction: if you make purchases on this card during the intro period, they can accrue interest at the regular rate.

It has a $0 annual fee, a balance transfer fee of 3% to 5%, and a regular APR of roughly 17.49%–27.49% variable. It also earns 2% cash back (1% when you buy, 1% as you pay), which Reflect does not. Choose it if your goal is specifically a balance transfer and you want ongoing rewards afterward. Verify the BT-only terms at Citi.

Chase Freedom Unlimited: 15 months plus rewards

The Chase Freedom Unlimited offers 0% for 15 months, the shortest of the three, but it pairs the intro period with a full rewards program: 5% on Chase Travel, 3% on dining and drugstores, and 1.5% on everything else, with a $0 annual fee.

Its regular APR is roughly 18.24%–27.74% variable. This card fits someone who wants some interest-free room on purchases and ongoing cash back afterward, rather than the maximum payoff window. Note Chase's 5/24 rule can affect approval. Confirm whether the 0% applies to purchases, transfers, or both, plus any transfer fee, at Chase.

Purchase intro vs balance-transfer intro, and the fees

Two cards here, Reflect and Freedom Unlimited, advertise a 0% intro on purchases, while the Double Cash's 0% applies to balance transfers only. Match the card to your actual need: a 0% purchase offer does not help a balance transfer, and vice versa.

Also weigh the upfront balance transfer fee, which can offset the interest you save: Reflect charges 5%, while Double Cash charges 3% to 5%. On a $5,000 transfer, a 5% fee is $250 up front. After any intro period, the regular APR (roughly 17%–28% variable across these cards) applies to leftover balances, so aim to finish before it ends.
