Bank of America Business Advantage Unlimited Cash Rewards Mastercard Credit Card Review (2026): One Rate, No Categories, and a Balance Test

The terms describe the rate as $0.015 for every $1 of net purchases, which is 1.5% expressed the long way. There are no bonus categories, no merchant category code puzzles and no annual or quarterly ceiling: the rate holds as long as the account stays open with active charging privileges. For a business whose spending refuses to sit inside anyone's category definitions, that predictability is the product.

The relationship uplift is where the arithmetic changes. Bank of America measures a three-month combined average daily balance across business deposit and Merrill business investment accounts, then applies a fixed bonus to each purchase as it posts. Gold, at $20,000 to just under $50,000, adds 25% and makes the effective rate 1.875%. Platinum, at $50,000 to just under $100,000, adds 50% for 2.25%. Platinum Honors, at $100,000 and up, adds 75% for 2.625%. Because the measure is a three-month average rather than a month-end snapshot, cash parked briefly before a large purchase does not move the tier.

Rewards pay out as dollars: into an eligible Bank of America checking, savings or Merrill investment account, onto the card as a statement credit, or as a check that expires 90 days after issue.

The standing public offer pays $500 in cash rewards once at least $5,000 in net purchases posts within 90 days of account opening. It is limited to one $500 bonus per company and arrives within the next one to two billing cycles. Elevated versions appear from time to time; this is the version posted publicly. Net purchases exclude balance transfers, cash advances, fees, returns and adjustments, so only genuine spending counts toward the $5,000. And the application acknowledgment allows the bank to decline additional card accounts if the business entity currently has, or has had, another Bank of America business card in the preceding 24 months.

There is no travel credit, no lounge access and no statement credit program here. What it offers instead is administrative: employee cards at no extra charge, all earning the same 1.5%, and rewards redeemable on demand with no stated minimum and no conversion through a points currency.

The terms attached to the account deserve equal attention. Opening it grants a security interest and a contractual right of offset in deposit accounts the business or the owner holds at Bank of America or its affiliates, meaning those balances can be applied to card debt. The owner is personally liable for all charges on every card issued under the account. The bank may also fund a new line by reallocating available credit from an existing Bank of America card account rather than raising the overall limit.

Nothing to hold: no annual fee and no employee card fee. Purchases run 0% for the first seven billing cycles, then 16.74% to 26.74% variable based on personal or business creditworthiness at opening, indexed to Prime as of July 31, 2026 with disclosures accurate as of August 2026. Balance transfers carry that same variable rate from day one with no promotional period and a 5% fee. A cash advance runs 5% up front and then 27.74% variable. Foreign purchases carry a 3% fee, which erases two full years of rewards on any dollar spent abroad. There is no penalty APR, late fees are tiered at $0, $29, $39 and $49 by balance, and the due date falls at least 25 days after each cycle closes.

The strongest case belongs to a business that already keeps meaningful cash at the bank and wants a card it never has to manage. A firm with $100,000 across business deposit and Merrill accounts earns 2.625% on everything. It also suits companies running several employee cards with scattered spending, since there is no category to optimize.

Without a deposit relationship at the bank, this is a 1.5% card, and 1.5% is not a competitive flat rate in the current business card market. Anyone with concentrated spending in a single category will do better on a card that pays a bonus rate there, and businesses buying regularly in foreign currencies should look past it given the 3% surcharge. A company hoping to move an existing balance gets no help here either.

**Is there a limit on how much cash back I can earn?**

No. The terms state there is no cap on total cash rewards as long as the account stays open with active charging privileges, and the rate is identical on the first dollar and the millionth, including spending on employee cards. Cash rewards also do not expire while the account is open.

**How does Bank of America measure my Preferred Rewards for Business tier?**

By a three-month combined average daily balance across eligible Bank of America business deposit and Merrill business investment accounts. Gold begins at $20,000, Platinum at $50,000 and Platinum Honors at $100,000, and the matching bonus is applied as each purchase posts rather than at redemption.

**Does opening this card put my personal finances on the line?**

Yes, in two ways. The owner agrees to be personally liable, in an individual capacity, for all charges and fees on every card issued under the account, and the application grants the bank a security interest and right of offset in deposit accounts held at Bank of America or its affiliates.

The rate on the card and the balance in the bank are one decision, not two. At Platinum or Platinum Honors this becomes a 2.25% or 2.625% card with no fee, no categories and no ceiling. Below roughly $50,000 in qualifying balances the case thins quickly, and below $20,000 it disappears, leaving a flat 1.5% and a 3% foreign transaction fee to justify themselves alone.
