Bank of America customers are waking up to an uncomfortable math problem.
The bank's flagship savings account still pays a national average of just 0.01% APY, according to the latest data compiled by Bankrate and DepositAccounts.
That means $10,000 parked there for a full year earns you roughly $1.00—barely enough to cover a vending machine soda.
The gap has widened dramatically since the Federal Reserve's rate-hike cycle pushed online banks and credit unions into the 4% to 5% range on high-yield savings accounts.
While those rates have cooled somewhat as the Fed signals cuts, the spread between a big-bank savings account and a top online account remains one of the most lopsided deals in personal finance.
So why do millions of Americans keep their cash at Bank of America anyway?
Convenience, branch access, and inertia top the list.
Many customers also qualify for the bank's Preferred Rewards program, which boosts credit card cash back and waives certain fees based on combined balances.
But even the top tier doesn't move the savings rate needle much—Preferred Rewards members still earn a fraction of what a basic online savings account pays.
Bank of America does offer promotional rates on some fixed-term products, like Certificates of Deposit, and its Merrill Edge self-directed investing accounts can tie into the rewards tiers.
A CD might make sense if you're certain you won't need the money for the full term, since early withdrawal penalties can wipe out months of interest.
For everyday emergency savings, though, a liquid high-yield account is usually the better fit.
The practical move for most people isn't to close their checking account—switching direct deposits and autopay is a hassle.
It's to open a separate high-yield savings account at an FDIC-insured online bank and link it to their existing Bank of America checking.
Transfers typically take one to two business days, and the money stays federally insured up to $250,000 per depositor, per institution.
A few things to check before you jump: confirm the advertised APY isn't a temporary teaser rate, look for monthly maintenance fees or minimum balance requirements, and read whether the rate applies to your full balance or just a portion.
Some accounts tier their rates, paying the highest yield only on the first few thousand dollars.
If you're holding a large cushion—say, six months of expenses—the difference adds up fast.
On $15,000, the gap between 0.01% and 4.00% is roughly $600 a year.
That's not a rounding error; it's a car payment, a chunk of a vacation, or a solid start on next year's holiday budget.
None of this is a knock on keeping a checking account where you already bank.
It's a reminder that loyalty to a single institution rarely pays interest.
Your emergency fund has one job: be safe and accessible.
The takeaway: leaving idle cash in a near-zero savings account is a choice, and it's one the bank is counting on you to keep making.
