What the numbers are doing
Blue Cash Preferred's 6% on groceries runs out: it applies to the first $6,000 of groceries spend a year, and everything past that earns 1%.
The table is earn rate only — annual fees are not netted out of it. These cards charge Blue Cash Preferred $95 and Cash Magnet Card $0 a year, so a thin lead in one category may not cover the difference.
Where they differ: Cash Magnet Card takes everything else; Blue Cash Preferred takes groceries, gas, ground transportation and streaming.
