Understanding MSME working capital: the operating cycle in plain language
What working capital is, how the operating cycle decides how much money a business needs, and how banks assess working capital limits for MSMEs.
Working capital is the money a business needs to keep running between paying for inputs and getting paid by customers. A profitable business can still run out of cash if its working capital is not planned. That is why it is the first thing a lender looks at.
The operating cycle
Every business has a cycle:
- Buy raw material or goods (cash goes out, or a creditor is created).
- Hold and process them (money is tied up in stock).
- Sell on credit (money is tied up in receivables).
- Collect from customers (cash comes back).
The longer this cycle, the more money is locked up at any time.
Worked example (illustrative numbers)
A small manufacturer has annual sales of ₹3.6 crore, about ₹30 lakh a month. It holds:
- Raw material: 1 month of consumption, about ₹18 lakh
- Finished goods: 0.5 month, about ₹12 lakh
- Receivables: 1.5 months of sales, about ₹45 lakh
Total current assets: about ₹75 lakh. Suppliers give it 1 month of credit, about ₹18 lakh. The working capital gap is about ₹57 lakh. Part of it is funded by the owner's own money (the margin) and the rest is what the business may ask a bank to finance.
Change one number, and the requirement changes. If customers start paying in 2.5 months instead of 1.5, receivables rise by about ₹30 lakh, and so does the cash the business needs.
How banks assess working capital limits
The RBI does not prescribe one formula. It advises banks to have Board-approved loan policies for MSE lending and to sanction limits "after proper appraisal of the genuine working capital requirements of the borrowers keeping in mind their business cycle and short-term credit requirement".
The RBI's MSME FAQ also records a long-standing benchmark: under the Nayak Committee report, working capital limits for small units are computed on the basis of a minimum of 20% of estimated turnover, for credit limits up to ₹5 crore. Lenders commonly describe this as the turnover method; for larger or more complex cases they analyse holding levels of each current asset in detail.
Turnover method (illustrative)
Projected annual turnover: ₹2 crore. Working capital requirement at 25% of turnover: ₹50 lakh. Borrower's margin at 5% of turnover: ₹10 lakh. Bank finance considered: 20% of turnover, ₹40 lakh.
Two more provisions are useful to know:
- Composite loans. Banks can sanction a composite limit of up to ₹1 crore so that an MSME can get its term loan and working capital through a single window.
- Term loan with working capital. The RBI advised banks that sanction a term loan to also sanction the working capital limit, so production is not delayed for want of working capital.
Which businesses count as MSMEs
Under the definition notified on 21 March 2025, classification depends on both investment in plant and machinery or equipment and turnover:
| Category | Investment up to | Turnover up to |
|---|---|---|
| Micro | ₹2.5 crore | ₹10 crore |
| Small | ₹25 crore | ₹100 crore |
| Medium | ₹125 crore | ₹500 crore |
Ways to reduce your working capital need
- Collect faster. Agree payment terms in writing. Under the MSMED Act, 2006, the agreed credit period between a buyer and an MSE supplier cannot exceed 45 days.
- Discount receivables from large buyers through TReDS; see understanding TReDS.
- Hold less stock. Review slow-moving items each quarter.
- Negotiate supplier credit, but pay on time to keep it.
Working capital is not a one-time number. Review it whenever sales, terms or products change, and before your limit comes up for renewal.
