Savings APY versus monthly fees: compare the dollars

A higher savings APY can still leave you with less money after a monthly maintenance fee. Compare the interest you would earn and the fees you would actually pay over the same period, using the balance you expect to keep.

The numbers below are hypothetical. They are not current offers or predictions of what any account will pay. Savings rates can change, and account requirements can affect both the rate you receive and the fees you owe.

To investigate actual options, compare savings rates, fees, and requirements. Use each provider’s current disclosures to check the terms that apply to your balance.

Put the interest and fee on the same timeline

Annual percentage yield, or APY, expresses interest on an annualized basis and reflects compounding under the applicable calculation assumptions. The CFPB’s APY calculation guidance explains that framework. A monthly maintenance fee is a separate cost you need to account for when comparing what you keep.

For a simplified one-year illustration, assume:

• You keep $5,000 on deposit for a 365-day year.
• The APY stays constant throughout that year and applies to the entire balance.
• Interest remains on deposit as assumed by the APY calculation.
• Any monthly fee is paid separately, so it does not reduce the deposit balance during the calculation.
• Taxes, bonuses, other charges, and additional transactions are excluded.

The separate-fee assumption matters. If a fee comes out of savings and you do not replace it, the lower balance can also affect the interest earned. Your actual results would then differ from this illustration.

Work through two hypothetical accounts

Option A pays a hypothetical 4.00% APY and charges a $10 monthly maintenance fee, with no waiver in this example. Option B pays a hypothetical 3.00% APY and has no monthly maintenance fee in this example. Neither description means that all other services are free.

At $5,000, Option A earns $200 in interest over the assumed year. Its twelve $10 fees total $120, leaving $80 after that fee cost.

Option B earns $150. With no monthly maintenance fee in the illustration, it leaves $150 before taxes and any other excluded costs.

Option A’s higher APY produces $50 more interest, but its maintenance fees cost $120. Option B therefore leaves $70 more under these assumptions. The comparison changes if the balance, rates, fees, or waiver eligibility changes.

Find the balance where the answer changes

In this simplified example, the APY difference is one percentage point, or 0.01 in decimal form. To offset $120 in annual maintenance fees, that difference would need to generate $120 more interest:

$120 ÷ 0.01 = $12,000.

At a constant $12,000 balance, Option A would earn $480, then leave $360 after the separate $120 fee cost. Option B would earn $360. That is the break-even point for these assumptions—not a universal balance for choosing a savings account.

The shortcut stops being reliable if an APY applies only to part of the balance, a rate changes during the year, or the fee is waived at a particular balance. Use the actual terms rather than extending the example to an account with different conditions.

Check whether the fee really applies to you

Some accounts have conditions that waive a maintenance fee. The CFPB’s maintenance-fee guide explains that requirements can include a minimum balance or qualifying deposits. Read the specific conditions and consider whether you can meet them consistently.

Then check access, transfer needs, and other service charges. An account that works on a spreadsheet may still be awkward for money you need quickly or move frequently.

Before choosing, write down three figures for your own comparison: expected interest over the chosen period, applicable fees over that period, and the difference. Recheck them when your balance or the account’s terms change.
