This lesson introduces the operating cycle and cash conversion cycle as central frameworks for understanding working capital dynamics. It covers the calculation of inventory, receivables, and payables periods, and how these are combined to determine the firm’s cash requirements, as taught in global corporate finance curricula.

• The Operating Cycle: The operating cycle is the average time it takes from the purchase of inventory to the collection of cash from customers. It is the sum of two components:

  • Inventory Period: The number of days inventory is held before being sold.

  • Receivables Period: The number of days it takes to collect payment from customers after a sale.

• The Cash Conversion Cycle (CCC): The cash conversion cycle, also known as the net operating cycle, measures the time between a firm’s payment for its raw materials and the receipt of cash from its customers. It is calculated as:

  • CCC = Inventory Period + Receivables Period – Payables Period

  • The payables period is the number of days the firm takes to pay its suppliers. The critical cash conversion cycle is the engine driving your business, and learning how to optimise Days Inventory Outstanding, Days Sales Outstanding, and Days Payable Outstanding accelerates cash flow and fuels growth .

• Short-Term Financial Planning and Cash Flow: Short-term financial planning is essentially working capital management. Short-term financial decisions involve short-lived assets and liabilities and are more easily reversed than long-term decisions. Key questions addressed include: Should the company borrow in the short-term? Should the company extend credits to customers? How much cash should be kept to pay bills? .

• Tracing Cash and Net Working Capital: Understanding the sources and uses of cash is critical for working capital analysis. Cash inflows and outflows are unsynchronized and uncertain. Cash is generated from:

  • Increases in long-term debt, equity, current liabilities, or decreases in current assets other than cash and fixed assets .

• Cash Flow Forecasting: Cash flow forecasting is essential for anticipating cash surpluses and deficits, allowing the firm to plan for investments or arrange financing in advance. Short-term financial planning is a core component of the module on Cash and Liquidity Management .
