The meaning and importance of working capital

Working capital refers to the funds a business requires to cover its day-to-day operational expenses, such as paying wages and purchasing stock.

Reasons why working capital is essential

• Meeting short-term obligations - Businesses need adequate working capital to pay immediate debts, like supplier bills or employee salaries, to avoid becoming illiquid.
• Avoiding financial distress - Insufficient working capital can result in creditors forcing the business into administration or liquidation if debts cannot be settled.
• Balancing excess funds - Holding too much working capital ties up money in stock, debtors, or unused cash, creating an opportunity cost as these funds could be invested elsewhere for better returns.

Calculating working capital and the working capital cycle

Working capital is determined by subtracting a business's short-term debts from its short-term assets. This calculation helps assess whether the business has enough liquid resources to operate smoothly.

Formula for working capital

$\text{Working capital}=\text{current assets}-\text{current liabilities}$

Where:

• Current assets = Items that can be converted to cash within a year, such as stock, debtors, and cash in hand (£)
• Current liabilities = Short-term debts due within a year, such as overdrafts and trade payables (£)

The working capital cycle

The working capital cycle measures the time taken from purchasing raw materials to receiving payment from customers. A longer cycle increases the need for working capital, as funds are tied up for extended periods.

Factors influencing the working capital cycle:

• Industry type - Businesses with long production processes, like manufacturing, often have longer cycles.
• Sales patterns - Seasonal demand can extend the cycle if stock is held for peak periods.
• Credit terms - Generous terms to customers lengthen the cycle, while strict supplier terms shorten it.

Worked example - Calculating working capital

A business has current assets of £78,000 (including £35,000 in stock and £43,000 in debtors) and current liabilities of £52,000 (including £28,000 in trade payables and £24,000 in overdrafts). Calculate the working capital.

Step 1: Identify the values

• Current assets = £78,000
• Current liabilities = £52,000

Step 2: Apply the working capital formula

$\text{Working capital}=\pounds \mathrm{78,000}-\pounds \mathrm{52,000}=\pounds \mathrm{26,000}$

Financing working capital

Businesses typically fund their short-term assets using short-term liabilities, but this approach carries risks. As a business grows, it may need more stable, long-term funding to support permanent increases in working capital.

Sources of finance for working capital

• Short-term sources - Include bank overdrafts and trade credit from suppliers, which are flexible but can create liquidity issues if over-relied upon.
• Long-term sources - Such as bank loans or issuing shares, which are suitable for expansion when working capital needs become ongoing.

Risks of financing approaches:

• Depending only on short-term finance can lead to cash shortages during unexpected events.
• Expansion often demands a permanent rise in working capital, making long-term options more appropriate to avoid constant refinancing.

Techniques for managing working capital components

Effective management of working capital involves strategies to optimise stock levels, creditor payments, and debtor collections. These techniques help shorten the working capital cycle and improve liquidity.

Inventory management techniques

• Minimising stock holdings - Maintain lower levels to reduce storage costs and tied-up capital.
• Using technology - Implement computer systems to monitor sales and stock in real time.
• Efficient controls - Adopt measures to prevent losses from theft or damage.
• Just-in-time ordering - Order materials only when needed to avoid excess inventory.
• Faster deliveries - Speed up shipments to customers to accelerate cash inflows.

Trade payables management techniques

• Extending payment terms - Delay payments to suppliers to retain cash longer.
• Selecting suppliers wisely - Choose those offering favourable credit periods.

Trade receivables management techniques

• Cash sales policies - Encourage or require immediate payment to avoid delays.
• Shortening credit periods - Reduce the time allowed for customers to pay invoices.

Financing approaches for capital and revenue expenditure

Capital expenditure involves spending on long-term assets, like machinery, while revenue expenditure covers short-term operational costs, such as utilities. The financing method depends on the expected duration of the expenditure.
