Discover it Cash Back: worth a spot in your wallet?

The honest math on the Discover it Cash Back: what its cash back earns beyond a plain 2% card and what its protections would cost to buy.

Discover · No annual fee · cash back

Earning rates

5x Rotating quarterly bonus categories ($1,500 in combined purchases per quarter (then 1%), activation required each quarter)
1x Everything else

No Foreign Transaction Fees — Discover charges no foreign transaction fee on purchases made outside the US.

Verified accurate — no benefit or fee changes. Fee, the $1,500/quarter rotating cap, and the card's lack of purchase/travel protections re-confirmed against discover.com and secondaries.
Refreshed the rotating-category examples to the live Q3 2026 categories (gas stations, transportation, drug stores) — display text only; no valued field depends on the specific quarter.

Added discover-it-cash-back (new card, $0 annual fee), researched from discover.com with a Bankrate cross-check (issuer page, Bankrate).
Earning: 5% rotating quarterly bonus categories (activation required each quarter, $1,500 combined spend cap per quarter — valued through an opt-in "how much of the cap would you realistically capture?" question, never assumed), 1% unlimited on everything else (source).
Benefits: No Foreign Transaction Fees is the card's only listed benefit — Discover eliminated purchase protection, extended warranty, price protection, and return protection card-wide in Feb 2018 and has not reinstated any of them (Bankrate).
True flat cash back (1¢/$ redemption via statement credit, deposit, or gift card), single preset per the null-currency convention.
Not included: Cashback Match (unlimited first-year dollar-for-dollar match of all cash back earned) — out of scope as a first-year-only welcome-style bonus per the calculator's sign-up-bonus exclusion rule; only ongoing/ordinary-year earning is modeled.

Valuation upgrade; no fee or fact changes. The 5% rotating quarterly categories now drive the same opt-in capture question as Freedom Flex's, instead of sitting as an unvalued display chip.
