Factors Affecting Working Capital Working capital consists of current assets like receivables, inventories, and cash. Several factors affect the required level of working capital including: 1) the nature of the industry, with larger industries requiring more working capital; 2) creditors' demands for adequate asset coverage of liabilities; and 3) the general nature of the business, with manufacturing requiring more working capital due to slower inventory and receivable turnover than services. Other key factors are inventory and receivable turnover, sales volume, production cycle length, and price level changes. Proper management of these factors can optimize the balance between liquidity and profitability of a firm's working capital.
