Bank Account Fee Leak Calculator

How checking fees quietly erode cash

Maintenance fees waived with direct deposit still count as real friction when the waiver fails. ATM owner fees, out-of-network issuer fees, wires, and overdraft-related charges often dwarf the advertised monthly price.

Annualizing the leak turns a set of small annoyances into a number you can compare to interest earned on the same balances — negative carry is common.

How to use this calculator

Open your bank’s personal account fee schedule PDF — not the marketing page. Enter monthly maintenance (waived or not), typical ATM events, wires, and any episodic fees you actually incur.

Run a waived year and an un-waived year if your direct-deposit pattern is irregular. Then compare the annual total to yield on a competing account.

Worked example

$12 monthly maintenance when the waiver fails ($144/year) + eight out-of-network ATM events at $3 issuer + $3 owner ($48) + two domestic wires at $25 ($50) + one returned-item fee at $35 ≈ $277/year of leak before FX travel fees.

Against $5,000 average checking balance earning 0.01% APY, yield is trivial. A no-fee account or a higher-yield parking strategy only makes sense after you count waiver reliability and transfer friction.

If you also send remittances abroad, price FX markup separately with the remittance calculator — corridor spreads often exceed checking fees.

How to use the number

Compare annual leak to interest earned and to the cost of time spent chasing waivers. Conditionally “free” accounts are priced products with behavioral requirements.

Travelers should read the ATM/abroad fee guide; domestic fee hunters should start with the bank fees checklist.

Assumptions

• Fees you enter are annualized with simple multiplication — no interest on the fees themselves.
• Waiver reliability is your judgment; the tool does not predict direct-deposit failures.
• Overdraft/NSF policies vary; enter only fees you actually face under your bank’s rules.
• No credit union dividends or account bonuses modeled automatically.
• Educational arithmetic — not a bank comparison broker.
