The Citi® Double Cash Card looks like a boring 2% cash-back card, and if you use it alone, it is. But held alongside a Citi Strata card, it quietly transforms into one of the best no-annual-fee transferable-points earners in the country: a flat 2x ThankYou points on everything, which you can move 1:1 into airline and hotel partners for premium-cabin awards. It's the "second card" that makes a Citi setup hum.

How the "double" cash actually works
You earn in two halves: 1% when you make a purchase, and another 1% when you pay it off. So the second half only lands when you pay your bill — an incentive baked into the card to keep you paying on time. Marketed as "2% cash back," the rewards actually accrue as ThankYou points at 2 points per dollar. That distinction is the whole trick: points are convertible; cash isn't.
What the points are worth
On its own, redeem for cash and you get a flat 1¢ per point — a plain 2% card. But hold an eligible Citi Strata Premier or Strata Elite in the same ThankYou account and you can pool the Double Cash points and transfer them 1:1 to Citi's partners, where we value ThankYou points at 1.8¢ each.
Our CPP formula for every award example on the site:
(cash price − taxes/fees) ÷ points × 100 = cents per point (CPP)
So the same $1,000 of spend is either:
- $20 cash (Double Cash alone), or
- 2,000 ThankYou points ≈ $36 in travel value (1.8¢) once paired — an 80% raise on identical spending, for $0 in extra fees.
Where your points can go
The Double Cash only unlocks transfers when it's paired with a premium Citi sibling — a Citi Strata Premier or Citi Strata Elite held in the same ThankYou account. Once paired, your pooled points transfer 1:1 to these airline and hotel programs — tap any partner to see how to use those points, what they're worth, and the best redemptions:

Earning rates
| Rate | Category |
|---|---|
| 2x | Everything (1x at purchase + 1x at payment) |
| — | No bonus categories, no caps, no activation |
The appeal is exactly this simplicity: nothing to track, no rotating categories, no spend limits. It's the card for all the spending your bonus-category cards don't cover.
Why pair it (the strategy)
- Fill the gaps. Put dining, gas, groceries and travel on a 3x card like the Strata Premier; put everything else on the Double Cash at 2x. Nothing earns below 2x.
- One shared point bucket. ThankYou points from all your Citi cards pool together, then transfer out as one balance.
- Free to keep forever. With no annual fee, it's a no-brainer long-term hold that also helps your credit-age and utilization.
- The catch: the transfer ability lives with the premium card. If you cancel your Strata card, your Double Cash points typically drop back to 1¢ cash value. Keep at least one Strata card open to preserve transferability.
A worked example
Say you spend $2,000/month on "everything else" (utilities, insurance, subscriptions, general shopping) that earns no bonus elsewhere:
- That's $24,000/year → 48,000 ThankYou points at 2x.
- Cashed out: $480.
- Transferred at 1.8¢: ~$864 in travel — enough, combined with a Strata bonus, to cover a one-way business-class award to Europe via Flying Blue or Turkish.
($4,000 lie-flat fare − $250 taxes) ÷ 50,000 miles × 100 = 7.50¢ — the kind of redemption those "boring 2%" points quietly fund.
Fine print worth knowing
- Foreign transaction fees apply (~3%) — leave this one home when you travel abroad; use a no-FTF card overseas.
- The 48-month Citi bonus rule applies across the ThankYou family; a recent Citi bonus can block any intro offer here.
- Points don't expire while the account is open. If you close every ThankYou-earning premium card, remaining points must generally be used before the account fully closes.
- The second 1% only posts as you pay your statement — carrying a balance both costs interest and delays that half of your rewards.
Who should get it
Get the Double Cash if you're building a Citi setup and want a free, no-think 2x card to catch all your uncategorized spending and feed the transfer program. It's not a standalone travel card — its whole value comes from the pairing.
On its own, most people are better served by a card that's transferable by itself, like the Chase Sapphire Preferred. Within the Citi world, the Double Cash + Strata Premier is the classic two-card combo; add the Strata Elite if you want lounges and credits on top.
Bottom line
The Double Cash is the unsung glue of a Citi points strategy: $0 fee, flat 2x on everything, and — paired with a Strata card — a real transferable currency instead of plain cash back. Keep one premium Citi card open to unlock transfers, and this becomes one of the highest-value no-fee cards you can carry.
