Bank of America Customized Cash Rewards Card: How the 3% Category Works

The Customized Cash Rewards card gives you one active 3% category at a time. Bank of America sets the list of six options — you pick from what's available, not from a category you define yourself. Your choice stays in place until you change it, and you can make that change once per calendar month through the mobile app or online banking. Switches take effect immediately and apply going forward, not retroactively to purchases already made.

The six eligible categories

• Gas and EV charging stations
• Online shopping — includes cable, internet, streaming services, and phone services billed online, not just retail purchases
• Dining — restaurants and food delivery
• Travel — airfare, hotels, rental cars, and vacation packages
• Drug stores and pharmacies
• Home improvement and furnishings

The merchant has to be coded in Bank of America's system under the right category for the 3% rate to apply. If a transaction doesn't code correctly — a gas station purchase that codes as a convenience store, for example — it earns 1% instead.

The $2,500 quarterly spending cap

The 3% category rate and the 2% grocery and wholesale club rate share a single combined quarterly cap of $2,500. Once your combined spending in those two tiers hits that threshold in a quarter, both tiers drop to 1% for the rest of that quarter. The 1% base rate on everything else has no cap at all. The cap resets at the start of each calendar quarter — January, April, July, and October.

For most cardholders spending at a moderate pace, $2,500 per quarter across two tiers is enough room that the cap never becomes a practical constraint. For high-volume spenders concentrating purchases in a single category, it's worth tracking.

Log in to Bank of America's mobile app or online banking portal and navigate to the card's rewards settings. The change saves immediately — there's no waiting period. You're allowed one change per calendar month, not per billing cycle, so the timing is tied to the calendar rather than your statement date.

Timing your switch strategically

• If a large purchase in a new category is coming up, switch before the transaction posts — switching after the fact won't help
• Switching mid-month does not apply retroactively to purchases already made that month
• If your spending is consistently concentrated in one category — say, you fill up a truck for work every week — there may be no reason to switch at all

The once-per-month rule is generous enough that cardholders with predictable but seasonal shifts in spending — heavier travel in summer, more home improvement spend in spring — can track their category to where the money is actually going.

For existing Bank of America customers, the card's earn rates can increase meaningfully through the Preferred Rewards program. Preferred Rewards boosts cash back by 25% to 75% depending on the combined deposit and investment balances you hold at Bank of America and Merrill. The multiplier is applied as a percentage increase to the base earn rate — it's not a flat add-on.

Preferred Rewards tiers

• Gold — $20,000–$49,999 in qualifying balances, 25% bonus: 3% becomes 3.75%
• Platinum — $50,000–$99,999, 50% bonus: 3% becomes 4.5%
• Platinum Honors — $100,000 or more, 75% bonus: 3% becomes 5.25%

The multiplier applies to all tiers — the 3% category, the 2% grocery tier, and the 1% base rate. At Platinum Honors, effective rates become 5.25%, 3.5%, and 1.75% respectively. For someone already keeping substantial balances at Bank of America, this stacking makes the card significantly more competitive without adding any annual fee.

No annual fee baseline

Because the card carries no annual fee, the rewards don't need to offset a recurring cost. Cash back is earned as reward points redeemable for statement credit, direct deposit to a Bank of America account, or credit to an eligible Merrill account. The card is issued by Bank of America, N.A., an FDIC member headquartered in Charlotte, NC, founded in 1904.

The card works best when your spending has a natural center of gravity — one category where most of your discretionary dollars land month after month. The 3% mechanic rewards focus. Cardholders who spread spending evenly across groceries, gas, dining, and travel with no clear concentration may find a flat-rate cash back card simpler to manage.

Cardholders who get the most from it

• People with predictable monthly spending concentrated in one or two categories
• Existing Bank of America customers eligible for Preferred Rewards, where the multiplier meaningfully increases effective earn rates
• Cardholders who want cashback flexibility without paying an annual fee
• Consumers who want one card to cover a primary spend category at 3% and use groceries and wholesale clubs as a 2% fallback

Where it's less likely to fit

• Cardholders who spend heavily across many categories with no clear concentration — a flat-rate cash back card may be simpler and earn more overall
• Travelers who want points transferable to airline or hotel loyalty programs — this card earns cash back, not transferable points
• Spenders who regularly exceed $2,500 per quarter across the 3% and 2% tiers — the cap limits upside for high-volume spenders in those categories
