How banks assess your working capital requirement

Business owners are often surprised that their working capital limit does not simply scale with turnover in a straightforward way. Two businesses with the same annual sales can be assessed for meaningfully different working capital limits, because the assessment is driven not by turnover alone but by how that turnover translates into stock, debtors and creditors — the actual operating cycle of the business. Understanding the method banks use turns the working capital conversation from something that feels arbitrary into something a promoter can plan around.

The operating cycle is the starting point

Every business has an operating cycle: raw material is bought (often on credit), converted into work-in-progress and then finished goods, sold (often on credit to the customer), and eventually converted back into cash when the customer pays. The length of this cycle — how many days stock sits, how many days debtors take to pay, offset by how many days the business itself takes to pay its own suppliers — determines how much cash is tied up in the business at any given time, and that tied-up cash is exactly what working capital finance exists to fund.

The two common assessment methods

Indian banks commonly use one of two broad approaches to arrive at an assessed working capital figure. The turnover method estimates working capital requirement as a percentage of projected annual turnover, with the bank funding the larger share and the business contributing the remainder as margin. The operating cycle (or holding levels) method instead builds the requirement up directly from actual or projected levels of stock, receivables and creditors, which tends to give a more precise, business-specific figure, particularly for larger facilities or businesses with an operating cycle that does not fit a simple turnover-based rule of thumb. Which method a bank applies, and the precise assumptions used within it, depends on the lender's own policy and the size of the facility — this should be discussed directly with the lender rather than assumed from a general rule.

A simplified worked illustration

Margin money and your own contribution

Whichever method is used, the bank does not typically fund the entire working capital gap — the business is expected to contribute a portion itself, commonly referred to as margin money, usually in the form of net working capital already built up in the business (current assets funded by long-term sources rather than short-term borrowing). A business with very little of its own margin locked into working capital may find its assessed bank finance capped below what the full operating cycle would otherwise suggest, simply because it has not built up sufficient own contribution.

Why the current ratio comes up in these conversations

Lenders commonly check the current ratio (current assets divided by current liabilities, including the proposed bank finance) as a broad indicator of short-term financial health once the working capital limit is factored in. A ratio that looks stretched after the proposed limit is added in can prompt a lender to reconsider the size or structure of the facility, or to ask the promoter to bring in additional own contribution, rather than proceeding with the full requested limit.

What a business can do to improve its position

1. Track your own operating cycle regularly (stock days, debtor days, creditor days) rather than only at renewal time.
2. Build up net working capital over time so your own contribution to the working capital gap grows, improving your assessed position.
3. Manage debtor collection actively — a shortening collection period directly reduces the assessed gap.
4. Avoid unnecessary build-up of slow-moving or obsolete stock, which inflates the gap without adding value.
5. Keep CMA data and actual financials consistent, so the bank's assessment reflects your true operating cycle rather than an unclear or contradictory picture.

A note on multiple banking and consortium arrangements

Larger working capital requirements are sometimes met through more than one bank, either under a formal consortium arrangement (banks jointly assessing and sharing the limit under a common agreement) or under multiple banking (each bank assessing and sanctioning independently, without a shared agreement). Each structure has different implications for coordination, security sharing and reporting, and the right choice depends on the scale of the requirement and the business's relationship with its bankers — this is a structuring decision worth discussing explicitly with an advisor or the lead bank rather than defaulting into one arrangement by accident.

Treat the annual review as a planning exercise, not a formality

Because working capital limits are reassessed at each renewal, the annual review is a genuine opportunity to reset the conversation with the lender rather than simply a compliance step to get through. A business that has grown its operating cycle needs, whether through longer customer credit terms, a larger stock base to serve new markets, or simply higher volumes, should treat the renewal as the moment to present that growth clearly, with the same discipline used in an original CMA submission, rather than waiting to be asked or assuming the existing limit will automatically be extended to match.

Equally, a business whose operating cycle has genuinely shortened — faster collections, leaner stock — has an opportunity at renewal to right-size its limit and reduce the commitment charges or margin money tied up in an underused facility. Reviewing the operating cycle honestly each year, rather than carrying forward the same limit indefinitely, keeps the working capital facility matched to the business as it actually is, not as it was when the limit was first sanctioned.
