Citi Double Cash review

Best for

The Double Cash is for someone who wants to consolidate existing debt and earn meaningful rewards on forward spending — without juggling two cards. The 2% flat earn rate (1% at purchase, 1% at payoff) is competitive with the best flat-rate cash-back cards on the market, and the 18-month 0% intro on transfers is enough runway to clear a $5,000–$8,000 balance with steady fixed payments. It's a strong default card for someone who values simplicity over category-tier complexity.

Not for

If your only goal is dropping a big balance to zero, a longer-window card will save you more interest. It's also the wrong pick for anyone who can't reliably pay off purchases in full each month — you only earn the second 1% on payments toward purchases, and any new spend during the intro window accrues interest at the regular APR. Travelers should look elsewhere given the 3% foreign-transaction fee.

Transfer fee math: when this card actually wins

Citi's intro 3% transfer fee (in the first four months) is one of the lowest on a card with this length. Take a $6,000 balance currently at 21% APR — that's about $1,260 in annual interest, or roughly $1,890 over 18 months at typical revolving rates. Move it to the Double Cash and you pay $180 upfront and $0 interest if you clear it before month 19. Net savings: roughly $1,710. Layer on $1,500 a month in regular spending earning 2% back, and you add another $540 in cash back across the intro window — the rewards effectively offset 3x the transfer fee. We are not a card issuer; final terms come from Citibank N.A.

The fine print: APR, fees and gotchas

The 0% intro APR applies only to balance transfers, not purchases. The 3% intro transfer fee window is four months from account opening — transfers initiated after that revert to a 5% fee. The first 1% in cash back is earned at purchase; the second 1% is earned only when you pay for that purchase, which can take a billing cycle to post. Late payments may end the intro APR. The post-intro APR ranges from 18.49–28.49% based on creditworthiness.

How to apply

Pre-qualification is available on Citi's site without a hard credit pull. Decisions are typically issued in seconds. Once approved, request your transfer through the Citi mobile app within the four-month window to lock in the 3% transfer fee. Transfers post to the old issuer in 4–14 days. Set up two recurring auto-payments: a fixed monthly amount toward the transferred balance, and a separate "pay in full" rule for new purchases, so the rewards math stays clean.

Citi Double Cash vs. closest competitor

The natural cross-shop is the Chase Slate Edge, which takes the opposite approach — 0% on purchases for 18 months and an automatic APR-reduction feature, but no rewards. Pick the Double Cash if rewards on forward spending matter; pick the Slate Edge if your bigger problem is the post-intro rate. Readers prioritizing balance-transfer length over rewards should compare the Citi Diamond Preferred (same issuer, 21 months, no rewards) or the Discover it Balance Transfer for Cashback Match in year one.
