Working Capital Assessment Methods Banks Use

Last updated: 16 October 2026

Quick Answer: Indian banks use four main working capital assessment methods: turnover, maximum permissible bank finance (MPBF), cash budget and operating cycle. For micro and small enterprise limits up to ₹5 crore, RBI's MSME guidance sets limits at a minimum of 20% of estimated turnover. Above that, each bank's Board-approved policy decides.

Working capital assessment methods decide how large a cash credit limit a bank will sanction against stock and receivables, and how much of the funding the company must bring itself. A finance head preparing a fresh limit, an enhancement or the annual renewal faces one early decision: which method to build the projections around.

Each method is explained below from the borrower's side, followed by a method selector table and one manufacturer's numbers run through every method.

How Much of the Working Capital Gap Will a Bank Fund?

Only part of it. Every working capital assessment starts from the same arithmetic:

• Gross working capital is total current assets: raw material, work in progress, finished goods, receivables and other current assets.
• Net working capital is current assets minus all current liabilities.
• The working capital gap is total current assets minus current liabilities other than bank borrowings, chiefly trade creditors and other short-term dues.

The bank finances the gap less a margin that the borrower funds from owned funds and term loans. The methods differ mainly in how they size the need and the margin: a share of turnover, a share of the gap or of current assets under the two MPBF methods, the peak cash deficit, or the length of the operating cycle.

Turnover Method: The Nayak Committee Route for MSE Limits up to ₹5 Crore

The turnover method is the simplest of the four: it sizes the limit from projected annual sales instead of holding levels. RBI's frequently asked questions on MSME lending, updated on 29 July 2025, rely on the Nayak Committee report. Under it, working capital limits for small units are computed on a minimum of 20% of their estimated turnover, up to a credit limit of ₹5 crore. RBI's MSME Master Direction records that all scheduled commercial banks were advised in March 2001 to implement the Nayak Committee recommendations.

The working behind that floor is a three-way split, which RBI's Credit Facilities Directions for urban co-operative banks (updated 1 October 2026) spell out:

Illustration: a unit projecting ₹16 crore of sales has a requirement of ₹4 crore, a margin of ₹80 lakh and bank finance of at least ₹3.20 crore.

The bank tests whether the projected turnover is believable. Expect it to compare the projection with audited sales and GST returns, so a growth assumption well above the past trend needs an order book or added capacity behind it.

Tandon Committee Methods: How the Gap-Based Limit Is Worked Out

MPBF stands for maximum permissible bank finance. It comes from the Study Group that RBI constituted in July 1974 under Prakash Tandon, whose report set out three methods for working out the maximum permissible level of bank borrowings:

In the report, core current assets are the irreducible minimum inventory that keeps production continuous: raw material, process stock, finished goods and stores. Receivables are not part of the core. Method III treats that inventory as permanent and funds it from long-term sources. Where a borrower's existing net working capital already exceeds the 25% contribution, the report took the existing figure as the contribution instead.

The report called Method III the ideal and recommended that banks begin with Method I and move borrowers up over time. MPBF is no longer an RBI prescription. RBI's Annual Report for 1997-98 (para 1.26) records that all MPBF instructions were withdrawn on 15 April 1997, and that banks were to evolve their own assessment methods under Board-approved loan policies. For urban co-operative banks, an earlier RBI master circular recorded that the MPBF prescription, based on a 1.33:1 minimum current ratio, had been withdrawn, leaving each bank to set its own current ratio.

A bank that still runs the MPBF calculation does so under its own policy. The holding levels it tests come from the projected current assets in the CMA data the company submits.

Cash Budget Method for Seasonal Businesses

The cash budget method finances the largest cumulative cash shortfall that a month-wise budget shows, rather than a share of sales or current assets. For limits above ₹5 crore for micro and small enterprises, or ₹1 crore for other borrowers, RBI's directions for urban co-operative banks let a bank adopt the turnover method, cash budgeting or any other method it considers necessary.

Of all the working capital assessment methods, this one best suits businesses whose needs swing through the year. Illustration: a spinning mill buys most of its cotton in the season, so its stock and its payments peak together for a few months. A month-wise budget of receipts from yarn sales against payments for cotton, wages, power and loan instalments shows the peak deficit, and the limit is sized to that peak.

Expect the bank to test the budget against last season's bank statements, so assumed credit periods must match how buyers actually paid.

Operating Cycle Method: Holding Periods From Raw Material to Receivables

The operating cycle method builds the requirement from the number of days money stays locked at each stage:

1. Raw material: days of consumption held in stock.
2. Work in progress: days of cost of production.
3. Finished goods: days of cost of sales.
4. Receivables: days of credit allowed to buyers, on sales.
5. Less trade creditors: days of purchases that suppliers finance.

Each holding level is the annual figure multiplied by the days and divided by 365. Illustrative: raw material consumption of ₹1,460 lakh a year, held for 75 days, ties up ₹300 lakh. Adding the stages gives total current assets; subtracting creditors and other current liabilities gives the gap, which the bank funds after the borrower's margin.

The method is only as good as its holding periods. Banks compare them with past years, and a receivable period that lengthens every year draws questions. Current customer ageing, kept in-house or through accounts receivable outsourcing, makes these figures easier to defend.

Which of the Working Capital Assessment Methods Will Your Bank Apply?

It depends on the size of the limit and on the bank's own policy. For MSE limits up to ₹5 crore, the turnover method sets the floor. Above ₹5 crore, the method, the margin and the acceptable current ratio come from each bank's Board-approved loan policy, not from an RBI formula.

Manufacturing unit or trading concern

A manufacturer is usually assessed on a gap-based working, MPBF or the operating cycle, with holding levels for raw material, work in progress and finished goods. A trading concern has no work in progress; stock and receivable days dominate, and turnover is often the cleaner base.

Service business or contractor

With little inventory, the limit rests on receivables, unbilled work and a cash budget built on billing milestones.

Mid-term review on actual sales

For micro and small borrowers, para 4.4 of RBI's MSME Master Direction carries one relevant provision. Banks must write into their lending policies a mid-term review of regular working capital limits, done each year on the previous year's actual sales, wherever the bank accepts that the borrower's demand pattern now needs a higher limit. A company expecting growth should prepare that case before the renewal date.

The sanctioned limit is not what can be drawn on a given day: drawing power, set periodically from the value of eligible current assets in the stock statement, decides that.

Working Capital Assessment Methods Compared on One Manufacturer's Numbers

The selector maps five common borrower situations to the method a bank tends to apply; treat it as a guide, since your bank's policy decides.

Now one illustrative engineering unit, a small enterprise, in ₹ lakh. Projected turnover is 2,400, so the turnover method puts its requirement at 25% of that, or 600.

Total current assets are 1,000 (raw material 300, work in progress 80, finished goods 170, receivables 400, other 50). Current liabilities other than bank borrowings are 350, so the working capital gap is 650. Core current assets are taken at 200.

The same balance sheet supports anything from ₹250 lakh to ₹487.5 lakh of bank finance. Ask which of the working capital assessment methods your bank's policy applies before the projections are finalised, not after the appraisal note arrives.

Who Builds the Assessment Inputs for the Bank?

Usually the company's own finance team, sometimes with outside help:

• The in-house finance team, where it already produces monthly MIS, stock and receivable ageing and a rolling budget.
• An outsourced finance desk with a virtual CFO layer, where the team keeps the books but has no time for projections.
• An independent practitioner engaged for one application or enhancement.

Whichever of the working capital assessment methods the bank applies, the projections must tie to the audited accounts, the GST returns and the stock statements it already holds. If the bank calls for a chartered accountant's certificate, the company engages a chartered accountant in practice to issue it.
