Same issuer, same approval bar, different earning shape
Discover it Chrome and Discover it Cash Back are both $0-annual-fee cards from the same issuer, both suggested around a 580 credit-score floor (Discover's more accessible tier), and both carry Discover's standard first-year cash back match. Where they differ is how the ongoing rewards actually work.
The rate table
| Discover it Chrome ($0) | Discover it Cash Back ($0) | |
|---|---|---|
| Gas stations & EV charging | 2% (shared cap, see below) | 1% |
| Dining & fast food | 2% (shared cap, see below) | 1% |
| Rotating 5% categories | Not offered | Up to 5%, changes quarterly — not modeled |
| Category cap | $1,000/quarter combined across gas/EV + dining, then 1% | $1,500/quarter on rotating categories, then 1% |
| Category selection required | No — automatic | Yes — manual quarterly activation |
| Everything else | 1% | 1% |
| Foreign transaction fee | 0% | 0% |
Why Chrome's 2% is automatic and Cash Back's 5% isn't modeled
Discover it Chrome's 2% on gas stations, EV charging, dining, and fast food applies automatically — there's no activation step and no quarterly category to track, just a $1,000/quarter shared cap across those two category pairs before the rate drops to 1%. Discover it Cash Back works differently: its headline 5% runs on a category that rotates every quarter (grocery stores one quarter, restaurants the next, and so on), requires manual activation each time, and caps at $1,500 in quarterly spend. Because the active category changes on a schedule this app can't predict from a static spend profile, that 5% isn't included in Cash Back's modeled rate here — which is why the table above shows Cash Back earning a flat 1% outside gas/EV/dining, even though real-world Cash Back holders who activate every quarter can out-earn that in the categories that happen to be live.
What this means in practice
If your spend concentrates in gas, EV charging, or dining and fast food, Discover it Chrome's automatic 2% is the more reliable pick — you get the rate every quarter with nothing to remember. If you're willing to check Discover's app each quarter, activate the current 5% category, and your spending happens to land in whatever category is live, Discover it Cash Back can out-earn Chrome in those specific quarters — but that's a real behavioral requirement, not something either card's rate table guarantees on its own.
Who should pick which
- Choose Discover it Chrome if: your spend is steady across gas, EV charging, dining, and fast food, and you'd rather have an automatic rate than track a rotating category.
- Choose Discover it Cash Back if: you're willing to activate Discover's rotating 5% every quarter and your typical spend tends to land in whatever category comes up.
- Either way: both share the same $0 fee, the same 0% foreign transaction fee, and the same accessible approval bar, so neither is a worse "starter" card than the other — the difference is entirely in how actively you want to manage the reward.
Run the optimizer with your real spend mix to see how either Discover card compares against a broader category-bonus setup.
