QAB charges in a bank are the penalty/fees you pay when you do not keep the required Quarterly Average Balance in your account.

What is QAB in simple words?

  • QAB = Quarterly Average Balance.
  • Banks tell you that you must keep a minimum average balance in your account over 3 months (a quarter).
  • If your actual average is less than this required amount, the bank deducts “QAB charges” (non‑maintenance charges).

Think of it like this: instead of checking your balance on just one day, the bank looks at your end‑of‑day balance for each day in 3 months, adds them up, and divides by the number of days to get an average.

How banks calculate QAB (easy example)

Banks typically do this:

  1. Take the closing balance of your account for every day in the quarter.
  2. Add all those daily balances.
  3. Divide by total number of days in that quarter (like 90 or 91).

If this average is below the required QAB (say required is 10,000 but your average is 7,000), the bank charges a penalty as per its fee list.

What exactly are “QAB charges”?

  • They are non‑maintenance or shortfall charges when the actual QAB is lower than the required QAB.
  • The charge amount often depends on:
    • How big the shortfall is (e.g., up to 50% shortfall vs above 50%).
* Your branch location type (rural, semi‑urban, urban, metro).

* Type of account (savings vs different tiers of current account).

For example, in some published PNB and other bank structures, higher shortfall or metro/urban branches face higher QAB charges per quarter.

Mini-view: QAB vs MAB

Some banks also use MAB (Monthly Average Balance) instead of QAB:

  • QAB: average over 3 months, penalty checked once per quarter.
  • MAB: average over 1 month, penalty can apply every month.

Depending on your cash flow style, QAB can sometimes be easier to manage, as good balances in some days of the quarter can offset low balances on other days.

Why banks use QAB and these charges

  • To ensure customers keep a minimum level of funds, which helps bank liquidity and reduces very low‑value, high‑cost accounts.
  • To compensate for service & operational costs when balances stay below required thresholds.

Regulator (like RBI in India) asks banks to clearly disclose all such charges on their websites and documents, so customers can check them beforehand.

Practical tips for you

  • Always check:
    • Required QAB for your specific account type and branch category (rural/semi‑urban/urban/metro).
* The exact slab‑wise shortfall charges from your bank’s official schedule of charges.
  • Use alerts or apps:
    • Turn on SMS/app alerts to track low balance periods.
    • Keep bigger inflows (salary, business credits) in the same account if you want to comfortably meet QAB.

If you got a “QAB shortfall recovery” entry in your statement, that is the bank deducting this non‑maintenance fee for that quarter.
