Working Capital Assessment Methods: A CAIIB ABFM Guide (2026)

Every bank credit officer eventually has to answer one practical question: how much short-term finance does a borrowing unit actually need? That is exactly what working capital assessment methods are designed to answer, and for CAIIB ABFM candidates this topic sits at the intersection of accounting, credit appraisal, and RBI-era lending discipline. Unlike long-term capital budgeting decisions, working capital assessment is a recurring, cyclical exercise that every branch-level and corporate-credit officer performs before sanctioning a cash credit or overdraft limit — which is exactly why examiners test it so heavily.

📐 Why Working Capital Assessment Methods Matter for Bank Credit

A firm's operating cycle — raw material to work-in-progress to finished goods to receivables to cash — creates a permanent funding gap that cannot be financed entirely from long-term sources. Banks bridge this gap through cash credit, overdraft, and working capital demand loans, but the sanctioned limit must be scientifically assessed, not guessed. This is where working capital assessment methods come in: they translate a borrower's projected turnover, current assets, and current liabilities into a defensible maximum permissible bank finance (MPBF) or drawing limit.

Historically, Indian banks used the same rigour they apply to capital investment decision and capital budgeting appraisal — the same discipline covered in our guide to capital budgeting techniques — projected cash flows, margin norms, and lending caps — but applied to a much shorter time horizon. Getting the assessment wrong in either direction is costly: under-financing starves the unit of operating liquidity and triggers delays across the production cycle, while over-financing lets a borrower divert bank funds into unrelated long-term uses, defeating the purpose of the sanction.

💡 Exam Tip: ABFM questions often frame working capital assessment as "which method would the bank use for a borrower with X turnover" — memorise the eligibility thresholds, not just the formulas.

🧮 The Traditional Route: MPBF Under the Tandon Committee

The Tandon Committee (1975) gave Indian banking its enduring framework for working capital lending. It proposed three methods of computing MPBF, all built around the idea that a borrower must fund a minimum margin of current assets from long-term sources (net working capital) rather than lean entirely on the bank.

• Method I: MPBF = 75% of (Current Assets − Current Liabilities other than bank borrowing). Working capital gap financed 75:25 by bank and borrower.
• Method II: The borrower must first provide 25% of total current assets (not just the gap) from long-term sources, tightening the margin requirement further.
• Method III (Chore Committee refinement): Excludes core current assets from the computation, pushing borrowers toward an even higher own-margin contribution.

These norms were later made largely advisory rather than mandatory, giving banks discretion in fixing their own working capital assessment methods through internally approved loan policies — but the underlying logic (a fixed margin on current assets, tested against turnover) still anchors most bank credit models today.

⚠️ Common Mistake: Students often confuse "current ratio" as computed under Method I (which yields roughly 1.33:1) with a general accounting benchmark. It is a lending-specific minimum, not a universal solvency rule.

Sound short-term liquidity planning of this kind is really an extension of the basic of management and planning principles introduced early in the CAIIB ABFM syllabus — see Basic of Management & Planning for the foundational planning concepts that working capital assessment builds on.

📊 Turnover Method vs MPBF: A Side-by-Side View

For small and medium borrowers, the elaborate Tandon-style computation was simplified in 1997 on the recommendation of the Nayak Committee into the turnover method, which pegs working capital finance directly to projected annual sales rather than a detailed current-asset build-up. Choosing the right one of the working capital assessment methods for a given borrower is itself an exam-favourite decision point.

Note that the borrowing entity's broader financing choices — including how leverage and capital structure decisions are made at the balance-sheet level — still shape which of these working capital assessment methods a bank will insist on, since highly leveraged borrowers typically attract tighter margin scrutiny.

💧 Cash Budget Method for Seasonal and Project-Linked Borrowers

Neither the turnover method nor classic MPBF computation copes well with businesses whose cash needs swing sharply across the year — sugar mills, construction contractors, and seasonal traders being classic examples. For these, banks use the cash budget method: a month-by-month projection of cash inflows and outflows (collections, payments, wages, taxes) that reveals the peak deficit the bank actually needs to fund, rather than an annualised average.

This approach is also the natural tool for assessing working capital needs of project-linked borrowers once a facility moves from construction to commercial operation, and it dovetails with how special cases are appraised — see the syllabus discussion under special cases of valuation for parallel treatment of non-standard financing situations.

📌 Remember: Cash budget method finance is sanctioned against the peak deficit month, not the average monthly requirement — a frequent trap in numerical questions.

Interestingly, the same discipline of matching short-term funding to actual cash cycles shows up outside ABFM too. Even NBFCs assessed under the NBFC scale based regulation framework apply comparable liquidity-gap thinking when structuring working capital lines for their corporate borrowers, underlining how consistent this logic is across RBI-regulated lending.

Banks calibrate all of the above against RBI's broader prudential lending framework; the official reference point for working capital and related credit norms is maintained on the RBI Master Directions page, which every credit officer should bookmark alongside the CAIIB syllabus.

🔗 Where Working Capital Assessment Fits in the Bigger ABFM Picture

Working capital assessment methods rarely appear in isolation on the CAIIB ABFM paper — they are usually cross-tested alongside capital budgeting techniques for the long-term investment side of the same borrower's balance sheet, and against economic value added once profitability and capital-charge questions enter the picture. A borrower who looks efficient on a turnover-method working capital limit can still destroy value if its long-term capital structure is wrong, which is why examiners like to combine these threads in case-study questions. For a deeper dive into related valuation angles, the chapter on special cases of valuation is worth revisiting once the working capital fundamentals are locked in.
