Working Capital Terms for JAIIB AFM: Gross, Net, Gap and MPBF

Ashish sir fires off nearly a dozen terms in one short — gross working capital, net working capital, operating cycle, working capital gap, MPBF, margin, drawing power — and if you are new to JAIIB AFM they all sound like the same idea wearing different hats. They are related. They are not interchangeable. And the JAIIB paper lives in exactly that gap between "related" and "same". Watch the short first, then use this page to slow the same working capital vocabulary down until every term has its own shelf.

Gross and net working capital are not rivals

Everything else in this topic hangs off two definitions, so get them clean before anything else.

• Gross working capital is simply total current assets — stock, receivables, cash, short-term advances, prepaid expenses. The whole pile of short-term resources.
• Net working capital is current assets minus current liabilities. What survives after the short-term claims on the business have been settled.

Take a small manufacturer with current assets of ₹120 lakh and current liabilities of ₹80 lakh. Gross figure: ₹120 lakh. Net figure: ₹40 lakh. Same balance sheet, two very different answers — and an MCQ that just says "working capital" with no adjective in front of it is usually testing whether you noticed which one it wanted.

One more thing the short flags and students routinely forget: the net figure can be negative. If current liabilities exceed current assets, the firm is funding part of its short-term needs from nothing it actually owns. For most manufacturing borrowers that is a warning light. For a supermarket chain that collects cash instantly and pays suppliers in sixty days, it is simply the business model. Context decides whether the number is a red flag.

The operating cycle is what creates the need

A firm does not need finance because a textbook says so. It needs finance because cash goes out long before it comes back. The operating cycle measures exactly that lag:

Operating cycle = raw material holding + work-in-progress + finished goods holding + receivables period − creditors period

Now convert days into rupees. If annual cost of sales is ₹3.6 crore, the daily run rate is ₹1 lakh. Eighty-five days of that is ₹85 lakh — the honest size of the requirement. Notice that nobody had to guess. Shorten the cycle by ten days through faster collection and the requirement falls by ₹10 lakh without a single extra rupee of borrowing. That is the whole argument for why the operating cycle sits at the centre of the working capital chapter in AFM.

The working capital gap, margin and MPBF

Banks do not fund the entire current asset block. They fund the shortfall left after the borrower's own contribution and after the suppliers have already chipped in. That shortfall is the working capital gap:

Gap = current assets − current liabilities other than bank borrowing

The "other than bank borrowing" clause matters. Existing cash credit is excluded on purpose — you are sizing the requirement, not admiring the borrowing that already exists. The portion the promoter must bring is the margin. What the bank can lend after that is the maximum permissible bank finance, or MPBF, and the Tandon Committee gave us two methods that JAIIB still asks about constantly.

Work both on the same figures: current assets ₹120 lakh, other current liabilities ₹30 lakh, so the gap is ₹90 lakh.

Method II is tighter, and the reason is the number in the last row. By forcing the borrower to fund a quarter of all current assets rather than a quarter of the gap, it drags the current ratio to the classic 1.33:1. A third method carved out "core" current assets — the permanent minimum stock a firm can never actually run below — and pushed those onto long-term sources, which was stricter still and rarely applied in practice.

Read the exam question carefully here. The two methods differ by one small placement of the 75%, and the marks go to whoever kept them straight under time pressure.

Worth knowing for the branch as well as the exam: the RBI no longer prescribes MPBF as a mandatory ceiling. Banks are free to evolve their own systems — the turnover method, the cash budget method, or their own internal models — for assessing a borrower's requirement. The Tandon arithmetic survives because it is a sensible default and because the IIBF syllabus still teaches it, not because it is compulsory law. The current lending framework sits in the RBI's master circulars on management of advances.

Drawing power is the number that bites every month

Sanctioned limit and drawing power are the two terms students most often merge into one, and in a branch they behave completely differently. The limit is the ceiling the sanctioning authority approved. Drawing power is how much of that ceiling the borrower may actually operate this month, computed from the stock and book-debt statement just submitted.

Drawing power = (stock − sundry creditors) less margin + eligible book debts less margin

Say the statement shows stock of ₹60 lakh against creditors of ₹10 lakh, with a 25% margin on stock, plus book debts of ₹40 lakh at a 40% margin:

• Paid stock = 60 − 10 = ₹50 lakh, and after the 25% margin, ₹37.5 lakh
• Book debts of ₹40 lakh, after the 40% margin, ₹24 lakh
• Drawing power = ₹61.5 lakh

If the sanctioned limit were ₹67.5 lakh, the account can still only be drawn to ₹61.5 lakh until stock or receivables improve. Creditors are deducted for a simple reason: stock the supplier has not been paid for is not the borrower's to pledge. And an outstanding balance sitting above drawing power for a continuous 90 days is precisely how a perfectly ordinary account slides into NPA classification — which is why this small monthly calculation carries far more weight than its two marks suggest.

How JAIIB AFM actually asks this

• Definition swaps. A question gives current assets and current liabilities and asks for working capital — decide whether it wants the gross or the net figure from the options offered.
• Method I versus Method II. One computation, two formulas, and a distractor sitting in the options for whichever one you did not use.
• Operating cycle to rupees. Days are given, cost of sales is given, and you convert.
• Drawing power with creditors. The trap is forgetting to deduct creditors before applying the margin.
• Current ratio implications. Method II and 1.33:1 travel together; expect them in the same question.

Practise these on timed sets rather than on paper — the arithmetic is easy and the clock is not. Our free JAIIB mock tests have AFM-specific sets, the JAIIB course page maps the numerical chapters in syllabus order, and the day-wise study planner will slot AFM numericals into your remaining weeks so this chapter does not get pushed to the night before. If ratio analysis is the next gap, the blog archive carries the full quick-revision series.
