Charged on average balance, growing in dollar terms as the business succeeds.
On a $120,000 average balance, for services a flat fee often covers just as well.
Does the fee's dollar cost still make sense as the balance grows?
A Fee That Scales With Success Isn't Automatically a Fair Trade
A business bank fee that scales with your account balance means the bank earns more from you specifically because the business is doing well, not because it's providing meaningfully more service. John Bogle's published cost-matters principle treats a cost as worth checking against the actual value received, regardless of how it's structured. Cost matters applied to business bank fees that scale with your balance means calculating the dollar cost as the balance grows, not assuming a percentage-based structure is automatically fair. For example, consider a business account charging 0.15% of average balance annually, reasonable-sounding at a $20,000 balance, $30 a year. As the business grows and its average balance reaches $120,000, that same 0.15% now costs $1,800 a year, for essentially the same core account services the business used when the balance was much smaller. According to the Bogle eBlog, Bogle's own published writing treated checking a cost against the value actually received as essential, regardless of whether the fee is structured as a flat dollar amount or a percentage. As of July 2026, this is especially important if your business account's fee structure includes any balance-based or tiered component and your average balance has grown meaningfully.
Same account structure, a dramatically different dollar cost as the balance grows.
Calculate the Dollar Cost at Your Actual Balance
Per Vanguard's official corporate history, Bogle's founding emphasis on checking a cost's real dollar impact, not just its stated structure, applies directly to business banking fees. Reviewing CFPB guidance on business account fee disclosures, and comparing any idle balance against a competitive, FDIC-insured 4.20% APY option, addresses both the fee structure and the return on the balance itself.
| Situation | What it usually means | Next check |
|---|---|---|
| Balance-based or tiered fee, growing account balance | Fee cost is likely rising in dollar terms | Calculate the actual annual dollar cost at your current balance |
| Flat-fee account regardless of balance | Cost stays predictable as the business grows | Confirm the flat fee still covers your actual service needs |
| Fee recalculated and found reasonable at current balance | No immediate action needed | Recheck periodically as the balance continues to grow |
| Fee found excessive relative to services received | A real, addressable cost | Compare against flat-fee alternatives providing similar services |
Calculating the fee's actual dollar cost has real benefits: it reveals whether a percentage-based structure that seemed reasonable at a smaller balance still makes sense at a larger one. The risk of not checking, as the $1,800 example shows, is paying a meaningfully larger fee for essentially unchanged services, simply because the growth happened gradually and the fee structure was never re-examined. However, that said, it depends on whether the balance-based fee comes with genuinely additional services at higher balances compared to one that doesn't: the first may justify some of the increase, the second is a stronger case for switching to a flat-fee structure. If you're deciding whether to switch account structures, choose to compare against a flat-fee alternative if your balance-based fee has grown meaningfully in dollar terms without added services; choose to stay if the current structure includes real, additional value at your balance level. This is when this matters most: whenever your business's average balance has grown meaningfully since the account was first opened.
At your current balance, not just the stated percentage.
Some do; many don't meaningfully change.
Often a better structure once a balance grows meaningfully.
A fee that was reasonable once can become less so over time.
When This May Not Apply
A business account whose balance-based fee comes with genuinely additional services at higher balances, like dedicated support or enhanced cash management tools the business actually uses, may still represent reasonable value despite the higher dollar cost. This is especially important to confirm against services actually used, not ones included but unused.
