Working Capital Assessment Methods Compared: Turnover, MPBF and Cash Budget

Indian banks size a working capital limit three ways: the turnover method takes 20% of projected turnover, MPBF takes the working capital gap less a margin, and the cash budget method takes the peak monthly cash deficit. On identical projections they can differ by 70%. The method is a credit decision, not a formality.

Key facts

• All three methods are permitted, and the choice sits with the lender. RBI's Master Circular on Management of Advances states that banks "may determine the working capital requirements according to their perception of the credit needs of borrowers" and "may adopt turnover method or cash budgeting method or any other method as considered necessary" (RBI/2023-24/51, 25 July 2023, para 2.5).
• YuSight delivers 5x throughput at the same headcount on the extraction and standardisation work that all three methods sit on top of — because running three methods on one borrower is three times the arithmetic, on the same set of PDFs.
• The turnover method has a hard formula and a hard ceiling. "The working capital requirement is to be assessed at 25% of the projected turnover to be shared between the borrower and the bank, viz. borrower contributing 5% of the turnover as Net Working Capital (NWC) and bank providing finance at a minimum of 20% of the turnover" — applicable to fund-based working capital limits up to ₹5 crore for micro and small enterprises and ₹1 crore for others (same circular, paras 2.1–2.2).
• MPBF is a convention, not a mandate. "The earlier prescription regarding Maximum Permissible Bank Finance (MPBF), based on a minimum current ratio of 1.33:1, recommended by Tandon Working Group has been withdrawn", and "banks may evolve an appropriate system for assessing the working capital credit needs of borrowers whose requirement are above Rs.1 crore" (RBI, *Master Circular on Management of Advances*, updated to 30 June 2004, paras 3.1.2 and 3.1.3). This is an archived Master Circular; confirm the current consolidated instruction applicable to scheduled commercial banks before quoting the paragraph numbers in a policy document.
• The working capital problem it is all trying to size is real and large. RBI's Expert Committee on MSMEs found that average MSME debtor days have "been consistently running over 90 days" and the gross working capital cycle "has always" exceeded 300 days (*Report of the Expert Committee on Micro, Small and Medium Enterprises*, chaired by U K Sinha, 25 June 2019).

Where does each method come from, and what is it really measuring?

RBI's own 2004 circular pointed at the third method for exactly the reason lenders still use it: "since major corporates have adopted cash budgeting as a tool of funds management, banks may follow cash budget system for assessing the working capital finance in respect of large borrowers" (para 3.1.3(b)).

The rest of this page runs all three on one borrower. Nothing changes between the runs except the method.

The borrower

All figures below are illustrative and constructed to demonstrate the method. They are not client data.

Annapurna Agro Mills LLP, Raichur, Karnataka — paddy procurement and rice milling, selling to two institutional buyers and three retail brands. Registered as a small enterprise. Existing cash credit limit ₹5.00 crore, outstanding ₹4.90 crore at 1 April 2028.

Projections for FY2029 (year ending 31 March 2029), as submitted in the CMA pack:

The one fact about this business that matters more than any of those numbers: 80% of the year's paddy is bought in the ten weeks between mid-October and December. Milling and selling run all twelve months. That is the fact each method handles differently, and it is why they disagree.

Method 1 — the turnover method, line by line

The "lower of 20% of turnover, or 25% of turnover less actual NWC" step is standard bank practice and appears in most loan policies, but the RBI text quoted above sets only the 25%/5%/20% sharing and does not itself prescribe the lower-of test. Confirm the wording in the lender's own policy before relying on it in a note.

Two things to note. First, the borrower's projected NWC of ₹1.65 crore is above the 5% floor of ₹1.20 crore, so the bank funds less, not more. A borrower who tightens their own balance sheet gets a smaller limit under this method — which is the correct outcome and routinely surprises the borrower.

Second, the method has now been applied without anyone asking how long paddy sits in a silo, what the credit terms to the retail brands are, or what happens in December. It took one input. That is its purpose and its defect.

Method 2 — MPBF, both Tandon methods, same numbers

Build the current assets from the holding periods the borrower has projected.

Working capital gap = TCA − OCL = 10.00 − 2.00 = ₹8.00 crore. Projected NWC = ₹1.65 crore.

Method I

• Minimum margin = 25% of the working capital gap = 0.25 × 8.00 = ₹2.00 crore
• Test (a) = 8.00 − 2.00 = ₹6.00 crore
• Test (b) = working capital gap − actual NWC = 8.00 − 1.65 = ₹6.35 crore
• MPBF Method I = lower of (a) and (b) = ₹6.00 crore
• Implied total current liabilities = 2.00 + 6.00 = ₹8.00 crore; current ratio = 10.00 ÷ 8.00 = 1.25 : 1

Method II

• Minimum margin = 25% of total current assets = 0.25 × 10.00 = ₹2.50 crore
• Test (a) = 10.00 − 2.50 − 2.00 = ₹5.50 crore
• Test (b) = 8.00 − 1.65 = ₹6.35 crore
• MPBF Method II = lower of (a) and (b) = ₹5.50 crore
• Implied total current liabilities = 2.00 + 5.50 = ₹7.50 crore; current ratio = 10.00 ÷ 7.50 = 1.33 : 1

The ₹0.50 crore difference between the two methods is exactly a quarter of other current liabilities — 0.25 × 2.00 — and it always is. The algebra behind that identity, and behind the 1.33 : 1 that Method II produces automatically, is worked through in MPBF calculation explained.

What MPBF has now done that the turnover method did not: it has looked at the operating cycle. What it still has not done: it has looked at the operating cycle once, as an annual average. The 96-day finished goods holding is a mean across twelve months. In December it is far higher; in September it is far lower. The method has no way to represent that.

Method 3 — the cash budget, month by month

Run the twelve months of FY2029, opening from the actual bank borrowing outstanding on 1 April 2028 of ₹4.90 crore. Figures in ₹ lakh.

Assumptions stated on the face of the budget:

• Collections lag sales by approximately 48 days, consistent with the receivables holding period used above.
• Paddy procurement: ₹11.28 crore (80% of the year's ₹14.10 crore of purchases) falls in October, November and December — ₹3.76 crore a month. The remaining ₹2.82 crore spreads across the other nine months at ₹0.31 crore a month.
• Wages, power, milling overheads, interest, term loan instalments and taxes run at a steady ₹0.74 crore a month.

Read the last column, not the first three. The borrower needs ₹7.46 crore in December 2028 and ₹0.14 crore in September 2028. Average outstanding across the twelve months is ₹3.67 crore — the sum of the twelve monthly balances, ₹44.04 crore, divided by twelve.

Three numbers come out of one table that no other method produces:

A flat ₹7.50 crore cash credit limit would run at 49% average utilisation and cost the bank capital on the undrawn portion all year. The structure the cash budget actually argues for is a regular limit of ₹5.00 crore plus a peak-season sub-limit of ₹2.50 crore, operative October to January, released against stock statements rather than sanctioned open-ended. Nothing in the turnover method or MPBF gets you to that recommendation.

Four numbers, one borrower — what does the spread mean?

Same borrower. Same projections. Same holding periods. A spread of ₹3.11 crore, and the highest number is 1.71 times the lowest.

The ordering is not random, and it is worth reading as a sequence:

• The turnover method is lowest because it is a flat percentage that takes no account of a 96-day finished goods holding. It would leave this borrower ₹3.11 crore short in December.
• Method II sits above it because it actually measures the operating cycle, and below Method I because its margin is charged on total current assets rather than on the gap.
• The cash budget is highest because it is the only method that sees December. Both MPBF methods averaged the year and produced a limit that is adequate for ten months and insufficient for two.

There is a fourth reading, and it is the uncomfortable one. Under the turnover method this file never leaves the simplified track: ₹4.35 crore is inside the ₹5 crore MSE ceiling, so no full CMA pack, no holding-period challenge, no cash budget. Under MPBF or the cash budget it crosses ₹5 crore and becomes a different kind of proposal entirely, with a different approval authority. The method decides the track, and the track decides how hard the file gets looked at.

What does the ₹5 crore threshold do to behaviour?

The turnover-method ceiling is a real number with real consequences, and both sides of the table respond to it.

• Borrowers ask for ₹4.95 crore. A limit inside the ceiling clears faster, needs less documentation and often needs less collateral — and, in particular, no full seven-statement CMA pack.
• Relationship teams size to the ceiling rather than to the cycle, then meet the December shortfall with ad-hoc limits — which are priced higher, reviewed less carefully, and roll over until someone notices they have become permanent.
• Analysts inherit a file where the assessment method was chosen before the operating cycle was understood.

The defensible practice is the opposite order: build the current assets and liabilities first, run the cash budget if the business has any seasonal shape at all, and only then decide which number goes into the sanction note. If the turnover method happens to be the answer, it is now a conclusion instead of a default.

Which method suits which borrower profile?

At the top of that table the structure is prescribed, not chosen. Borrowers with aggregate fund-based working capital limits of ₹150 crore and above must take a minimum share of the limit as a working capital demand loan — 40% from 1 April 2019, raised to 60% from 1 July 2019 (RBI/2018-19/87, *Guidelines on Loan System for Delivery of Bank Credit*, 5 December 2018).

What must the analyst check in each method?

Turnover method — three checks

1. Is the projected turnover credible? Compare it against the GST outward supplies series and the bank credit summary before you multiply anything by 0.20.
2. Is the borrower's actual NWC above or below 5% of turnover? Below, and the shortfall is a condition precedent. Above, and the limit comes down.
3. Is the business genuinely non-seasonal? If not, the method is being used because it is quick, not because it fits.

MPBF — five checks

1. Re-derive every holding period from the audited columns. Two of three drifting in the borrower's favour is the normal pattern, not an anomaly.
2. Confirm that the working capital gap equals TCA minus OCL from the CMA's statement 4. If it does not, the MPBF has been reverse-engineered from a target limit.
3. Confirm that current maturities of term debt sit inside other current liabilities. Leaving them out inflates the limit one-for-one — the failure worked through in CMA data vs project report.
4. Check which test binds. Where test (b) governs, both methods give the same answer and the borrower's NWC is doing the work.
5. Check the resulting current ratio against the covenant the sanction will carry, alongside TOL/TNW.

Cash budget — four checks

1. Do the twelve monthly receipts sum to something consistent with projected sales less the movement in debtors? If not, the collection assumption is doing the work.
2. Are the procurement months right? Ask for two prior years of monthly purchases from the GST returns and overlay them.
3. Does the peak month coincide with a stock statement date? If it does not, the drawing power on the peak date will not support the peak drawing — see the drawing power calculator.
4. Has anyone tested a downside? Push collections out by fifteen days and re-read the peak. On this borrower that alone moves the December number by roughly ₹1 crore.

That last point is where the cash budget earns its keep, and also where it becomes dangerous. A cash budget is only as good as its assumptions, and unlike a balance sheet it has no internal consistency check. A borrower who wants a larger limit does not need to falsify anything — only to be pessimistic about collections.

How does the drawing power interact with all of this?

None of the three methods produces the number the borrower can actually draw next month. They produce the limit. Drawing power is computed separately, from the latest stock and book debt statement after margins, and the borrower always gets the lower of the two.

For a seasonal borrower this matters more than for anyone else. Annapurna's December peak of ₹7.46 crore is backed by paddy stock bought that quarter — but only if the stock statement is filed on time, the valuation basis is the one the sanction specifies, and the margin on paddy is the one the policy prescribes. The interaction between the two numbers, and the covenant structure around it, is set out in drawing power vs ratio covenants in cash credit facilities.

How does YuSight handle this?

Running three assessment methods on one borrower is three sets of arithmetic on one set of documents: audited financials for two years, a CMA workbook that arrives as a locked spreadsheet or a scanned PDF, GST returns to test the turnover projection, and twelve to twenty-four months of bank statements to test the collection assumption in the cash budget.

YuSight's Financial Spreading module extracts and standardises those financials, computes the liquidity, leverage, coverage and turnover ratios, and traces every figure back to the document and page it came from — analyst-editable, so the holding-period judgement stays with the credit officer where it belongs. The extraction and standardisation step is what delivers 5x throughput at the same headcount; the decision about which method fits this borrower is not automatable and should not be.

The practical effect is that running the cash budget stops being the thing you skip because there was no time. On a file like this one, skipping it is a ₹3.11 crore difference of opinion with yourself.

FAQ

What are the methods of working capital assessment?

Three are in general use in India. The turnover method takes a flat 25% of projected sales as the requirement and funds 20% of it. MPBF takes the working capital gap and deducts a 25% margin, measured either on the gap or on total current assets. The cash budget method takes the largest monthly cash deficit over the next twelve months.

When should a bank use the cash budget method?

Whenever the year has a shape. Seasonal procurement, milestone-linked receipts, single large orders, or a business new enough to have no holding periods to derive from — in all of those, an annual average is the wrong unit of measurement and will produce a limit that is wrong in both directions at different times of year.

Which method suits seasonal businesses?

The cash budget, with MPBF run alongside as a sanity check. In the worked example above, MPBF Method II gave ₹5.50 crore and the cash budget showed a December peak of ₹7.46 crore. Both are correct answers to different questions; only one of them keeps the mill running in December.

Is MPBF still mandatory?

No. RBI withdrew the MPBF prescription and told banks to evolve their own assessment systems for requirements above ₹1 crore. What most banks then did was write Method II into their own board-approved loan policy, so it is still the working default at most lenders — as policy, not as regulation.

Why does the turnover method give a smaller limit here?

Because it multiplies sales by a fixed percentage and never asks how long the stock sits. A rice mill holding 96 days of finished goods has a much longer cycle than the 25%-of-turnover assumption contemplates, so the formula under-funds it. For a trading business turning stock over in three weeks, the same formula would over-fund.

Can a bank use more than one method on the same file?

Yes, and on any borrower with a seasonal or lumpy cycle it should. The usual practice is to compute MPBF for the balance sheet discipline it imposes, compute the cash budget for the peak, and then sanction a structure — a regular limit plus a seasonal sub-limit — that neither method produces on its own.

What happens if the borrower's actual NWC is above the required margin?

The limit comes down, under every method. The margin is a minimum contribution, not a target: if the borrower is already funding more of the current assets than the method requires, the bank funds the remainder, which is less. Borrowers find this counter-intuitive and it is worth explaining before the sanction letter does it for you.

Does the assessment method change the drawing power?

No. Drawing power is computed from the latest stock and book debt statement after margins, entirely independently of how the limit was assessed. The borrower draws the lower of the sanctioned limit and the drawing power, which is why a well-assessed limit with a badly-maintained stock statement still leaves the borrower short.

How many months of data do you need to build a credible cash budget?

Twenty-four months of bank statements and GST returns, so the seasonal pattern appears twice. One year of history lets a borrower present an unusual year as the normal one, and the whole method rests on the shape of the year being right.

Key takeaways

• Three methods, one borrower, four numbers between ₹4.35 crore and ₹7.46 crore. The spread is not an error in any of them — each is measuring something different.
• The turnover method needs one input and is blind to the operating cycle. It is defensible for short-cycle trading and services, and indefensible for seasonal manufacturing.
• MPBF measures the cycle, but as an annual average. Method I always exceeds Method II by exactly a quarter of other current liabilities, which is why lenders standardised on Method II.
• The cash budget is the only method that sees the peak month. It is also the only one with no internal consistency check, so its assumptions have to be tested against GST and bank data, not accepted.
• The ₹5 crore MSE threshold changes behaviour on both sides of the table. Choose the method from the borrower's cycle, then see where the number lands — not the other way round.
• Whatever the assessed limit, the borrower draws the lower of the limit and the drawing power. A seasonal peak that is not supported by a stock statement on the peak date is a limit on paper only.
