Flexible 3% choice category with no annual fee
If you already bank with Bank of America and can qualify for a BofA Rewards boost, this card is an easy keeper: $0 annual fee, a 3% category you can switch monthly (6% for your first 12 months), and a useful 2% tier—great for everyday spend (within the $2,500/quarter cap), not big one-off purchases. Note that Bank of America renamed Preferred Rewards to BofA Rewards in May 2026 and moved the goalposts: the 75% boost now takes $1 million in balances instead of $100,000.
If you don't bank with Bank of America, this card usually isn't the standout. Citi Custom Cash is simpler and typically richer: it automatically gives 5% on your top eligible category each billing cycle (up to $500), no toggling required. Pair that with a basic 2% everywhere card and you'll beat 3% most months.

Step 1: Open a Bank of America checking account (that alone gets you the Member tier and a 10% boost, with no balance minimum)
Step 2: Maintain qualifying balances across your accounts to move up:
BofA Rewards boosts your earned cash back by:
The boost applies to your earned cash back after purchase, but doesn't change the $2,500 quarterly cap or your ability to change categories monthly.
