What is Average Quarterly Balance (AQB)?
Average Quarterly Balance (AQB) is the average of daily closing account balances maintained over a 3-month (quarterly) period in a savings or current bank account.
AQB Calculation Formula:
$$\text{AQB} = \frac{\text{Sum of Daily Closing Balances for All Days in Quarter}}{\text{Total Number of Days in Quarter (90 to 92 Days)}}$$
Unlike Average Monthly Balance (AMB), which evaluates account balances over a 30/31-day period, AQB covers an entire financial quarter:
- Q1 (Apr - Jun): 91 Days
- Q2 (Jul - Sep): 92 Days
- Q3 (Oct - Dec): 92 Days
- Q4 (Jan - Mar): 90 Days (91 in Leap Years)

Frequently Asked Questions (FAQ)
1. How is Average Quarterly Balance (AQB) calculated?
AQB is calculated by adding up your account's closing balance at the end of every day during the quarter and dividing that total sum by the total number of calendar days in that quarter (usually 90 to 92 days).
2. What happens if I fail to maintain the minimum AQB?
If your calculated AQB falls below the bank's mandated minimum threshold, the bank levies non-maintenance charges (NMC). These charges vary from ₹50 to ₹600 + GST per quarter/month depending on the bank and shortfall percentage.
3. Can I deposit a large sum at the end of the quarter to cover AQB shortfall?
Yes! Since AQB relies on cumulative daily balances, depositing a larger amount for the remaining days of the quarter can offset low balances maintained earlier in the quarter. Our calculator computes the exact deposit amount required.
4. Which Indian banks require Average Quarterly Balance (AQB)?
Many public and private Indian banks use AQB or AMB for specific account tiers, including HDFC Bank, ICICI Bank, State Bank of India (SBI), Axis Bank, Bank of Baroda, Kotak Mahindra Bank, Punjab National Bank, Canara Bank, IndusInd Bank, and IDFC FIRST Bank.
