When you open a savings account, you typically need to keep a specific balance in it, known as the Monthly Average Balance or MAB. Maintain it and you avoid MAB charges. Banks set an MAB so they can manage funds effectively and offer services such as cheque books, ATM access and branch transactions without billing you separately for each one.
MAB, which stands for Monthly Average Balance, is not the amount you must hold every single day. It’s the average of your daily closing balances across the month, which means a dip on one day can be offset by a higher balance on another. That distinction matters more than most people realise, and it’s where the confusion usually starts. Understanding what MAB means in banking and how MAB charges work gives you a clear picture of what your account actually costs you.
QUICK STAT
Banks collected Rs. 7,086.63 crore from customers in FY26 as penalties for not maintaining the prescribed MAB in savings and current accounts. Among private banks HDFC Bank collected the most at Rs. 1,798.14 crore, followed by Axis Bank at Rs. 1,081.33 crore. Public sector banks collected Rs. 2,137.92 crore between them.

MAB Full Form in Banking
MAB stands for Monthly Average Balance. You’ll also see it written as AMB, or Average Monthly Balance, which means the same thing. Some banks use a quarterly version instead, the Average Quarterly Balance or AQB, where the same maths applies but across three months rather than one.
It’s worth checking which one your bank uses, because the two behave quite differently. A quarterly average gives you far more room to recover from a lean month than a monthly one does.
What is Monthly Average Balance (MAB)?
MAB full form in banking refers to monthly average balance. It is the average balance you must keep in your savings or current account through a calendar month. The requirement varies by account type and, at many banks, by whether your branch is in a metro, urban, semi-urban or rural location. At the end of the month the bank calculates your MAB and levies a penalty if you’ve fallen short.
Some banks offer zero-balance savings and current accounts, which are a sensible option if you’d rather not track a threshold at all. They typically come with fewer of the add-on features that balance-linked accounts carry, so it’s a trade-off rather than a straight win.
How is Monthly Average Balance (MAB) Calculated? Formula & Steps
Your MAB is the average of your closing balance at the end of each day for the whole month. Here’s how it works:
- Note your account balance at the end of each day
- Add up all these daily closing balances
- Divide the total by the number of days in the month
PRO TIP
Every calendar day counts, including weekends and public holidays. On a non-working day the previous day’s closing balance simply carries forward, so a large withdrawal on a Friday costs you three days of low balance, not one.
Example of MAB Calculation
Take an account across a 30-day month:
| Period | Closing balance per day (Rs.) | Days | Sub-total (Rs.) |
|---|---|---|---|
| Day 1 to Day 10 | 5,500 | 10 | 55,000 |
| Day 11 to Day 20 | 5,100 | 10 | 51,000 |
| Day 21 to Day 30 | 5,600 | 10 | 56,000 |
| Total (30 days) | 30 | 1,62,000 |
MAB Calculation Result: What the Formula Gives You
Monthly Average Balance = Total of daily closing balances / Number of days
= Rs. 1,62,000 / 30 = Rs. 5,400
So the MAB for that month is Rs. 5,400. If the month has 31 days, divide by 31 instead. February needs 28 or 29 depending on the year, which is why the same balance pattern can produce a slightly different MAB from one month to the next.
A Second Example: When the Shortfall Bites
Priya banks with a branch that requires an MAB of Rs. 10,000. Over a 30-day month she held Rs. 18,000 for the first 10 days, dropped to Rs. 6,000 for the next 10 after paying rent, then went back up to Rs. 12,000 once her salary landed.
Her total is (10 x 18,000) + (10 x 6,000) + (10 x 12,000) = Rs. 3,60,000. Divided by 30, that’s an MAB of Rs. 12,000. She’s comfortably clear, even though her balance sat at Rs. 6,000 for a third of the month.
Now change one thing. Suppose she held Rs. 18,000 for only the first 5 days and Rs. 6,000 for the remaining 25. Her total drops to Rs. 2,40,000, giving an MAB of Rs. 8,000 against a Rs. 10,000 requirement. That’s a shortfall of Rs. 2,000, and at a typical rate of 6% of the shortfall she’d be charged Rs. 120 plus GST. The takeaway: it isn’t how low your balance goes, it’s how long it stays there.
What Are MAB Charges?
MAB charges, also called non-maintenance charges, are what your bank levies when your monthly average balance falls below the required threshold. They are a service fee rather than a regulatory penalty, and banks set them at their own discretion. RBI Governor Sanjay Malhotra has confirmed that minimum balance limits for savings accounts are decided by individual banks and do not fall under regulatory jurisdiction.
Banks use one of three structures, sometimes in combination:
- A percentage of the shortfall, commonly 5% or 6% of the gap between your actual MAB and the required amount
- A flat monthly fee, regardless of how large the shortfall is
- A percentage of the shortfall subject to a cap or floor, such as 6% or Rs. 600, whichever is lower
GST applies on top of the charge in every case. Most banks debit it automatically at month end and show it on your statement, so it’s easy to miss if you’re not looking.
DID YOU KNOW?
A shift worth knowing about: 10 of India’s 12 public sector banks have now completely discontinued penal charges for non-maintenance of MAB on savings accounts. SBI dropped them in March 2020, Canara Bank from 1 June 2025 and PNB from 1 July 2025. Private banks have largely gone the other way.
MAB Charges: Bank-wise Comparison Table
Requirements vary widely by bank, account variant and branch location. This is a snapshot for regular savings accounts, not an exhaustive schedule:
| Bank | MAB requirement (regular savings) | Charge for non-maintenance |
|---|---|---|
| State Bank of India | Nil | None. SBI waived savings account minimum balance charges in March 2020 |
| Punjab National Bank | Nil | None, with effect from 1 July 2025 |
| Canara Bank | Nil | None, with effect from 1 June 2025 |
| HDFC Bank | Rs. 10,000 urban, Rs. 5,000 semi-urban, Rs. 2,500 rural (quarterly). An eligible FD can be held instead | 6% of the shortfall or a flat fee, whichever is lower |
| ICICI Bank | Rs. 10,000 for existing customers. Higher for accounts opened after August 2025, revised down after customer pushback | A flat fee plus a percentage of the shortfall |
| Axis Bank | Rs. 10,000 across branches, or an FD of Rs. 50,000 instead | 6% of the shortfall, subject to a cap |
| Kotak Mahindra Bank | Rs. 10,000 to Rs. 20,000 depending on the variant | 6% of the shortfall, capped at Rs. 500 a month |
| Union Bank of India | Rs. 1,000 metro and urban, Rs. 500 semi-urban, Rs. 250 rural (quarterly) | Varies by segment |
| BSBDA and Jan Dhan accounts, all banks | Nil | None. Exempt from minimum balance requirements |
Reasons to Maintain a Minimum MAB
Staying above the threshold does more than spare you the charge. These are the practical upsides:
- Chances of earning more interest: banks pay interest on your savings balance, so a higher balance earns more. Rates vary by bank and by balance slab
- Access to offers: a healthier balance can qualify you for reward points, lifestyle benefits, a personal loan at a preferential rate or discounts on other financial products
- Financial discipline: an MAB requirement discourages you from drawing the account down to nothing, which makes tracking expenses and holding to a budget considerably easier
- A repayment buffer: keeping a cushion in the account means an EMI or standing instruction is far less likely to bounce for want of funds
WATCH OUT
To be clear on one common misconception: your savings account balance is not reported to credit bureaus and your MAB has no direct effect on your CIBIL score. The link is indirect. A buffer helps you avoid missed EMIs and bounced auto-debits, and those do show up on your credit report.
Tips to Maintain the MAB
- Pick an account that matches how you actually bank. If your balance fluctuates, a lower MAB requirement or a zero-balance variant will cost you less than a premium account you can’t sustain
- Set a standing instruction to transfer funds in from another account on a fixed date each month
- Check whether your bank lets you hold a fixed deposit instead of cash. Several treat an eligible FD as satisfying the MAB, which means the money earns FD interest rather than savings interest
- Consider a sweep-in or money multiplier FD, where surplus above a set limit moves into a deposit automatically and returns when you need it
- Track your balance through the mobile app or NetBanking and set a low-balance alert rather than checking manually
- Review your statement each month so a non-maintenance charge doesn’t go unnoticed for half a year
If you’re consistently paying MAB charges, the account is the problem, not your habits. Ask your branch to convert it to a lower-threshold or zero-balance variant. Banks will usually do this on request rather than lose the relationship.
Maintaining a monthly average balance helps you avoid penalties and gives you access to a range of services and rewards at no extra cost. A steady balance is also a reasonable signal of financial stability, which can work in your favour when your own bank assesses you for a credit card or a loan.

FAQs on MAB Full Form, Charges & Calculation
1.What does MAB stand for?
MAB stands for Monthly Average Balance. You may also see it as AMB, or Average Monthly Balance, which means the same thing. Some banks work on an Average Quarterly Balance or AQB instead, calculated the same way but across three months.
2.What are MAB charges and how are they calculated?
MAB charges are the fee your bank levies when your monthly average balance falls below the required threshold. Banks calculate them as a percentage of the shortfall, usually 5% or 6%, or as a flat monthly fee, or a percentage subject to a cap. If your requirement is Rs. 10,000 and your MAB works out to Rs. 8,000, a 6% charge on the Rs. 2,000 shortfall comes to Rs. 120 plus GST.
3.How much is the MAB penalty for non-maintenance in SBI, HDFC or ICICI?
SBI does not levy any charge, having waived savings account minimum balance requirements in March 2020. HDFC Bank typically charges 6% of the shortfall or a flat fee, whichever is lower, against a requirement of Rs. 10,000 in urban branches. ICICI Bank applies a flat fee plus a percentage of the shortfall. Both private banks revised their requirements during 2025, so check your bank’s current schedule of charges rather than relying on a figure you read elsewhere.
4.Is there any savings account with zero MAB requirement?
Yes, several. Basic Savings Bank Deposit Accounts, including those opened under the Pradhan Mantri Jan Dhan Yojana, carry no minimum balance requirement and no non-maintenance penalty at any bank. SBI, PNB and Canara Bank have also removed the requirement from their regular savings accounts, and most private banks offer at least one zero-balance variant, often a digital or salary account.
5.What happens if MAB falls below the minimum required balance?
The bank debits a non-maintenance charge from your account at month end, plus GST, and it appears on your statement. Some banks give a grace period of around 30 days before the charge applies. Repeated shortfalls can also mean losing fee waivers on services like cheque books or ATM transactions, and if the balance stays low long enough the charges themselves can push the account into a negative balance.
6.Can I set up alerts to track my monthly average balance?
Yes. You can set customisable balance alerts through NetBanking or your mobile banking app. Most apps also show your MAB for the current month against the required amount, so you can see mid-month whether you need to top up rather than finding out after the charge is applied.
7.Can overdrafts affect my monthly average balance?
They can. An overdraft is a short-term facility to draw funds against your account, and drawing on it reduces your credit balance. Many banks compute MAB on the credit balance only, which means an overdraft drawdown can pull your average down. Practice varies between banks and account types, so confirm with yours rather than assuming it’s neutral.
8.Are there any rewards for maintaining a high monthly average balance?
There can be. A higher MAB may qualify you for lifestyle benefits, reward points, a personal loan at a preferential rate or discounts on other financial products. The specific benefits depend on your bank and your account variant, and premium variants generally require a much higher MAB in exchange.
