Formula and Logic
This tool uses standard banking industry calculations for minimum balance requirements:
- Average Daily Balance: Sum of each day’s account balance divided by the number of days in the month (this is your input value, as banks calculate this for you).
- Shortfall Calculation: If your current average daily balance is below the bank’s required minimum, shortfall = Required Minimum – Current Average Daily Balance.
- Annual Fee Cost: If you fall below the minimum, total annual fees = Monthly Maintenance Fee × 12.
The status result is determined by comparing your current average daily balance to the bank’s required minimum: if current ≥ required, you meet the requirement, otherwise you are below.
Practical Notes
These finance-specific tips will help you interpret your results accurately:
- Average daily balance differs from current balance: banks calculate this by adding each day’s ending balance and dividing by days in the cycle, so a large deposit on the last day will not count as much as consistent daily balances.
- Maintenance fees may increase if you are below minimum for multiple consecutive months, or trigger additional overdraft fees if your balance drops to zero.
- Some accounts waive fees if you have qualifying direct deposits or linked accounts, even if you fall below the minimum balance – check your account terms for these exceptions.
- Money market and savings accounts often have higher minimum balance requirements than checking accounts, but may pay interest if you meet the minimum.

Frequently Asked Questions
What is average daily balance?
Average daily balance is calculated by adding your account balance at the end of each day in a billing cycle, then dividing that total by the number of days in the cycle. Banks use this metric (not your current balance) to determine if you meet minimum balance requirements.
Can I use this for business bank accounts?
This tool is designed for personal banking accounts, but can be used for small business accounts with standard minimum balance structures. Business accounts may have additional fee tiers or transaction requirements not factored into this calculation.
Do minimum balance requirements apply to all account types?
No, many basic checking accounts have no minimum balance requirements, while premium checking, savings, and money market accounts almost always have minimum balance rules. Always check your account disclosure for official terms.
Additional Guidance
For the most accurate results, pull your average daily balance directly from your monthly bank statement, as this is the value your bank uses to assess fees. If you are close to the minimum balance, consider setting up low balance alerts with your bank to avoid accidental fees. Review your account terms annually, as banks may change minimum balance requirements or fee amounts with notice. If you consistently pay maintenance fees, compare accounts from other institutions to find a lower-cost option that fits your budget.
