Simple 2% Cashback on Everything
If you want simple, guaranteed money back with no annual fee, this is it. Citi Double Cash gives you 2% back on everything—1% when you buy and another 1% when you pay the bill—so you're rewarded for not carrying a balance. No categories to track, no quarterly activations, no "read the fine print" homework.
Two caveats: there's a foreign transaction fee (about 3%), so don't use it abroad, and it's a straight-shooting cash card—travel hackers will want a companion card later. Bottom line: a fantastic default, do-nothing card for everyday spend; add a travel card only if you're ready to learn the points game.
Citi Double Cash is an easy, guaranteed 2% back. If you want extra value, pair it with Citi Strata Premier (formerly Citi Premier): move your rewards into the Premier account, then transfer to airline/hotel partners for redemptions that can beat the simple "one cent per point" math. It's not magic—you'll need to learn award bookings and be flexible. Check out our Level 2 Travel Learning section.
