Working capital finance explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Once you know how much working capital the business needs, the next question is who will supply it. Part comes without effort from suppliers, part from the owners, and the rest usually from a bank. This guide describes the sources, the forms of bank credit, a method banks once used to size their lending, and how a small manufacturer can plan its own funding.
Working capital is financed by spontaneous sources (trade credit, accrued wages), negotiated sources (bank credit, bills, factoring, inter-corporate deposits) and the owners' own long-term funds. The gap that remains after trade credit and the owners' contribution is what the firm asks the bank for. Banks have used methods such as maximum permissible bank finance to size that amount, and they now frame their own methods. Plan the split in your own figures first, then discuss it with the bank.
Sources of working capital finance
A documented working capital assessment is usually the first paper a bank asks to see, so it helps to know the sources before it is drawn up.
Spontaneous sources grow with business: supplier credit, advances from customers, and accrued expenses such as wages and taxes payable. They carry no explicit interest, though a lost discount has a cost (see our article on receivables management).
Negotiated sources are arranged: bank credit in several forms, discounting of bills, factoring, short-term loans from related parties or other companies (inter-corporate deposits), and customer deposits.
Long-term funds invested in working capital: the owners' money and term loans that stay in the business. The permanent part of the need belongs here.
Forms of bank credit
| Form | How it works | Suits |
|---|---|---|
| Cash credit | A limit set against stock and debtors; draw and repay within it; interest on the amount used | Regular cycles of stock and debtors |
| Overdraft | The current account can go below zero up to a limit | Short, irregular needs |
| Bill discounting | The bank pays the bill amount less a discount now and collects at maturity | Trade bills from credit sales |
| Letter of credit | The bank commits to pay the supplier on documents; the buyer reimburses | Purchases from distant or new suppliers |
| Short-term loan | A fixed sum for a fixed time | Specific one-off needs |
Banks usually ask for periodic statements of stock and debtors. Our note on CARO clause 3(ii) in practice explains how auditors report them. Credit guarantee schemes can ease security for small units; see CGTMSE.
What maximum permissible bank finance meant
For many years, banks in India sized working capital loans by asking how much of the current assets should be financed by the borrower's own long-term funds and how much by the bank. The idea was to keep a part of current assets funded by long-term money, so that the bank was not financing the whole of the stock and debtors. Methods built on this idea were known by the name maximum permissible bank finance and by the names of the committees that proposed them. They are a matter of history: banks now frame their own assessment methods, and this article states no formula, percentage or current norm. What matters to a borrower is the underlying concept. The bank will look at how much of the need the owners fund themselves, and the firm should arrive with its own plan.
Worked example: Narmada Auto Components
Narmada Auto Components, an invented small manufacturer, has projected current assets of ₹90 lakh: stock 40, debtors 45, cash and others 5. Suppliers' credit is ₹30 lakh. Net working capital need = 90 - 30 = ₹60 lakh. This is the figure that the method in working capital cycle produces.
The owner makes this funding plan (₹ lakh). The owner's contribution of 15 is the firm's own assumption, chosen because the owner is willing to lock in that much long-term money; it is not a rule. Rates are assumed: cash credit 11 per cent, bill discounting 9 per cent, owners' return 16 per cent. Average drawing of cash credit is 35 against a limit of 40, leaving headroom for peaks.
| Source | Amount | Assumed rate | Annual cost |
|---|---|---|---|
| Owner's long-term funds | 15 | 16% | 2.40 |
| Cash credit (average drawn) | 35 | 11% | 3.85 |
| Bill discounting (average outstanding) | 10 | 9% | 0.90 |
| Total funded | 60 | 7.15 |
Blended cost = 7.15 / 60 = 11.92 per cent. Test of structure: current liabilities after the plan are suppliers 30 + cash credit 35 + bills 10 = 75, so the current ratio is 90 / 75 = 1.20. The owner notes that a higher own contribution would raise this ratio and lower the borrowing, but at a cost of 16 per cent against 11 per cent. A lower contribution would cut cost but weaken the ratio and the bank's comfort.
Decision. Narmada applies for a cash credit limit of ₹40 lakh and a bill limit of ₹10 lakh, shows the funding plan with the owner's ₹15 lakh, and prepares the projected statements the bank will want; see projected financial statements for a bank loan. The owner also resolves to cut debtors from 45 days to 40, which would reduce the need by about 5 lakh.
Other sources
Trade credit is the cheapest source if terms are fair, but dependence on it can strain supplier relations. Inter-corporate deposits are quick but dear and short. Factoring and bill discounting convert credit sales into cash early. Customer advances reduce the need, which is a reason to ask for them on custom orders. The broader choice of funds is set out in our article on sources of finance.
Common mistakes
- Applying for a limit equal to the whole of current assets, not the gap.
- Using cash credit for permanent needs or for buying fixed assets.
- Ignoring the cost of unused limits and charges.
- Not matching the drawing pattern to the limit, which signals poor control.
- Treating the owner's contribution as costless.
- Quoting an old lending method to a bank as though it were still in force.
