Introduction

Bank of America Preferred Rewards is the simplest way to push a flat-rate cash back card past 2.5% without paying a premium annual fee. There are no transfer partners and no award charts. Park enough money at Bank of America or Merrill, and every personal credit card you hold earns 25%, 50%, or 75% more on the same purchases you were already making. As of April 2026, the tier ladder is unchanged, and the multiplier is still the most generous relationship bonus any major US issuer offers on credit card earning.

The program is worth understanding because it answers a specific question cleanly: what's the best no-annual-fee cash back card if you already keep meaningful balances at one bank? With Platinum Honors status, the answer comes from the Bank of America lineup.

How the Tiers Work

Preferred Rewards uses a three-month average combined balance across eligible Bank of America deposit accounts and Merrill investment accounts. Three tiers are relevant for credit card earning:

  • Gold ($20,000 to $49,999): 25% bonus on credit card rewards.
  • Platinum ($50,000 to $99,999): 50% bonus.
  • Platinum Honors ($100,000 or more): 75% bonus.

Two higher tiers exist (Diamond at $1 million and Diamond Honors at $10 million) and stack additional banking and wealth-management benefits on top. For credit card earning specifically, the bonus stays at 75% across Platinum Honors, Diamond, and Diamond Honors. The break point that matters for most cardholders is $100,000.

Eligible balances include checking, savings, money market accounts, CDs, and Merrill brokerage and IRA accounts. 529 plans and HSAs do not count. The three-month rolling average means a one-time deposit doesn't qualify you immediately. Move money in, then plan on roughly a quarter before the multiplier activates.

What the Multiplier Does to Each Card

The bonus applies to every personal Bank of America credit card on your account. Run the math on the four most common rewards cards in the lineup:

  • Travel Rewards ($0 fee, 1.5x base): becomes 1.875x at Gold, 2.25x at Platinum, 2.625x at Platinum Honors.
  • Premium Rewards ($95 fee, 2x travel and dining, 1.5x base): becomes 3x and 2.25x at Platinum; 3.5x and 2.625x at Platinum Honors.
  • Customized Cash Rewards ($0 fee, 3% chosen category): becomes 3.75% at Gold, 4.5% at Platinum, 5.25% at Platinum Honors.
  • Unlimited Cash Rewards ($0 fee, 1.5% flat): becomes 1.875% at Gold, 2.25% at Platinum, 2.625% at Platinum Honors.

The Customized Cash Rewards rate at Platinum Honors is the headline number. A 5.25% no-fee card on a category you choose monthly (gas, online shopping, dining, travel, drug stores, or home improvement) is competitive with any 5% category card on the market, and you don't have to enroll in rotating categories. The Unlimited Cash Rewards at 2.625% beats every flat-rate cash back card we track at the no-fee tier.

Welcome Bonus Angle

Each card carries its own welcome bonus, and Preferred Rewards multiplies the ongoing earn rate but not the welcome offer itself. As of April 2026, the Premium Rewards card is offering 60,000 online bonus points after $4,000 in spend in 90 days, which is worth $600 against travel statement credits. Customized Cash and Unlimited Cash both offer $200 cash rewards online bonuses after $1,000 in 90 days. Travel Rewards offers 25,000 points (worth $250 in travel credits) after $1,000 in 90 days. Confirm the current banner before applying, since BoA rotates these offers quarterly.

The strategic move: open the card after Preferred Rewards status is active, not before. Earnings on the spending requirement itself get the multiplier, which is real money. At Platinum Honors, the $4,000 spend on the Premium Rewards card earns 14,000 bonus points (worth $140) on top of the welcome offer instead of the base 8,000.

How to Qualify

Most households reach Gold or Platinum without much effort. Consolidate emergency fund and high-yield savings into a Bank of America savings account, and you're at $20,000 to $50,000 quickly. Platinum Honors at $100,000 typically requires moving brokerage assets to Merrill. Merrill Edge has commission-free stock and ETF trades and a competitive mutual fund lineup, so a brokerage transfer isn't a sacrifice for self-directed investors. For managed money, compare Merrill's expense ratios and advisor fees against your current setup before transferring; the rewards bonus has to clear that gap to be a net win.

A common qualifying mix at Platinum Honors: $20,000 in checking and savings, $60,000 in a Merrill brokerage account, $20,000 in CDs. Three accounts, one tier, all four card multipliers active.

Where the Program Falls Short

Preferred Rewards earns its reputation on simplicity, but the trade-off is real. Bank of America has no transfer partners, so no premium-cabin redemption strategy is possible. Points and cash back redeem at a flat 1 cent against statement credits or deposits. A reader chasing 4 cents per point through Air France-KLM Flying Blue or Air Canada Aeroplan is in the wrong ecosystem and should look at the Chase Sapphire Preferred instead. The relevant program comparison is in our Bank of America vs Chase rewards breakdown, which lays out the trade-offs by use case.

The other constraint: Preferred Rewards bonuses don't apply to small business cards. The personal lineup does the work. Self-employed earners running heavy business spend should pair the Platinum Honors-boosted personal cards with a separate business card from another issuer.

Bottom Line

For households that keep $50,000 or more at Bank of America or Merrill, Preferred Rewards turns no-fee cards into category leaders. A 5.25% card on a chosen category and a 2.625% card on everything else is a setup most issuers can't match without an annual fee. Verify your three-month average, pick the card matched to where you actually spend, and apply through Bank of America's site after the multiplier activates.
