Q.What is working capital? Discuss five important determinants of working capital requirement?

Working capital is the capital a business needs to meet its day-to-day operational expenses. It is the difference between current assets (like cash, inventory, and debtors) and current liabilities (like creditors and short-term loans). In simple terms, it is the funds required to run the short-term cycle of buying raw materials, producing goods, selling them, and collecting cash.

Five important determinants of working capital requirement are:

• Nature of Business: A trading or service firm needs less working capital because its operating cycle is short. A manufacturing firm needs more working capital because it has to hold raw materials, work-in-progress, and finished goods for a longer period.
• Scale of Operations: A larger business with higher sales volume will need more working capital to support its larger inventory and receivables. A smaller business will need less.
• Production Cycle: The longer the time taken to convert raw materials into finished goods, the larger the working capital requirement. A long production cycle means funds remain blocked in work-in-progress for a longer time.
• Credit Terms: If a business gives long credit to its customers (debtors), it needs more working capital. Conversely, if it gets long credit from its suppliers (creditors), its working capital requirement is lower.
• Seasonality: A business that sells only during a particular season (e.g., a woollen garment maker) will need a large amount of working capital during the peak season to build up inventory. Off-season, the requirement is much lower.

Working capital is the money a firm keeps circulating through its short-term operations -- buying raw materials, paying wages, holding stock, and financing the credit it extends to customers -- until that money returns as cash from sales. Unlike fixed capital, which is locked into long-term assets like plant and machinery, working capital keeps turning over within a short period. It is measured as net working capital: the excess of current assets (cash, marketable securities, bills receivable, debtors, inventories, prepaid expenses) over current liabilities (creditors, bills payable, outstanding expenses). Too little working capital and a firm cannot meet its payment obligations on time; too much and funds sit idle earning almost nothing, since current assets are liquid but low-yielding. A balance has to be struck between liquidity and profitability.

The amount required differs from firm to firm and industry to industry. Five important determinants are discussed below.

Nature of Business

The basic nature of a business is the single biggest influence. A trading firm buys and sells goods with little or no processing, so it can turn stock into sales quickly and needs a relatively small amount of working capital. A manufacturing firm must first convert raw materials into finished goods before any sale is possible, so its funds stay blocked for longer and its working capital need is higher. Service businesses, which usually hold no inventory at all, need the least working capital.

Production Cycle

The production cycle is the time span between the receipt of raw material and its conversion into finished goods. A firm with a long production cycle -- a distillery or a heavy-machinery maker, say -- keeps funds tied up in work-in-progress for months, so its working capital requirement is high. A firm with a short cycle, such as a bakery, recovers its cash quickly and manages with less.

Scale of Operations

A business operating on a larger scale carries a larger quantity of inventory and debtors, and therefore needs more working capital than one operating on a smaller scale. If a firm doubles its production and sales, it needs proportionately more raw materials, stock, and customer credit to support the higher level of activity.

Credit Allowed and Credit Availed

The credit terms a firm gives and gets have a direct effect. A liberal credit policy towards customers raises the level of debtors and increases the working capital required. On the other side, to the extent a firm avails credit from its own suppliers on purchases, its working capital requirement is reduced -- the supplier is effectively financing part of that cycle.

Seasonal Factors

Most businesses have some seasonality. In the peak season the level of activity is high, so a larger amount of working capital is needed to build up stock and meet demand; in the lean season the requirement falls. A maker of woollen garments, for instance, needs far more working capital before winter than during summer, and often meets the temporary peak through short-term bank finance.
