Fee estimation formulas
1. Maintenance fee
Maintenance_fee_month =
(Average_checking_balance < Min_balance_to_waive)
? Stated_maintenance_fee
: 0
2. Overdraft and ATM fees
Overdraft_fees_month =
Expected_overdraft_incidents × Overdraft_fee_per_incident
ATM_fees_month =
Out_of_network_ATM_count × Out_of_network_ATM_fee
3. Per‑transaction fees
Chargeable_transactions =
max(0, Total_transactions − Free_transactions_included)
Transaction_fees_month =
Chargeable_transactions × Per_transaction_fee
4. Total monthly fees
Total_fees_month =
Maintenance_fee_month
+ Overdraft_fees_month
+ ATM_fees_month
+ Transaction_fees_month
+ Other_monthly_fees
The forecast combines these components to give a rough estimate of what your bank relationship might cost each month under your assumptions.
Using fee forecasts to choose better accounts
Bank fees can quietly erode your cash flow. Forecasting them helps you compare accounts and decide whether to switch banks, change behavior, or seek fee waivers.
Common fee drivers
- Low balances that don’t meet minimums for fee waivers.
- Frequent overdrafts or out‑of‑network ATM usage.
- High transaction counts on accounts with limited free transactions.
Worked example
Suppose your forecast shows:
- $12 maintenance fee (balance below waiver threshold).
- $35 in overdraft fees (one incident).
- $6 in ATM fees (two out‑of‑network withdrawals).
That’s $53 per month, or over $600 per year. Seeing that number can motivate you to raise your average balance, switch to a no‑fee account, or change ATM habits.
