Our take
Discover it Cash Back suits people who don't mind a little quarterly homework. It pays 5% in rotating categories — gas, EV charging, flights, transit and rideshare, and drugstores all appear in its lineup — and it holds the number-one spot in SwipeCaddy's rankings for EV charging, transit and rideshare, and drugstores. With no annual fee, it fits households that can steer real spending toward whatever the quarter rewards.
The 5% comes with three strings attached. You have to activate each quarter, the bonus categories share a combined cap, and once you hit that cap the rate drops. Outside the rotating categories the card earns a flat 1%, which is a thin floor for everyday spending. There is no signup bonus either, so the first-year value rests on the Cashback Match, which doubles all the cash back you earn that year.
In a small wallet, treat this as the bonus slot, not the workhorse. Pair it with a flat-rate card that beats 1% for everything outside the active quarter, and pull out the Discover it Cash Back only where the 5% applies. Because rewards are plain cash back, every dollar earned is worth exactly a dollar, with no valuation math to second-guess. It also charges no foreign transaction fees.
The math
Run $200 a month of gas through this card and you're earning about $120 a year at our conservative valuations. There's no annual fee to earn back — everything above the 1% base rate is pure upside.
Where it lands in our rankings: #1 for drugstores · #2 for transit & rideshare · #3 for gas
