What is Working Capital?
Definition
Working capital is the difference between a company's current assets and current liabilities. It measures a company's short-term liquidity and operational efficiency, indicating whether it has enough resources to cover its near-term obligations.
Detailed Explanation
Working capital is calculated by subtracting current liabilities (accounts payable, short-term debt, accrued expenses due within one year) from current assets (cash, accounts receivable, inventory, and other assets convertible to cash within one year). Positive working capital means the company can pay its short-term bills; negative working capital may signal financial distress.
The working capital cycle describes how quickly a company converts its working capital into cash. It involves three main components: days inventory outstanding (DIO), days sales outstanding (DSO), and days payable outstanding (DPO). The cash conversion cycle equals DIO + DSO - DPO. A shorter cycle means faster cash generation.
Some industries naturally operate with negative working capital. Retailers like Walmart and Amazon collect cash from customers immediately but pay suppliers on 30-90 day terms, creating a float that actually funds their operations. This is a sign of strong bargaining power, not financial weakness.
Changes in working capital significantly affect free cash flow. A growing company that must invest heavily in inventory and receivables will see working capital consume cash, reducing FCF below net income. Conversely, a company that improves its working capital efficiency can generate FCF above net income.
Formula
Working Capital = Current Assets - Current LiabilitiesExample
A company with $500M in current assets (cash, receivables, inventory) and $300M in current liabilities (payables, short-term debt) has working capital of $200M.

Free Cash Flow
Free cash flow (FCF) is the cash a company generates from its operations after accounting for capital expenditures needed to maintain or expand its asset base. It represents the cash available for dividends, debt repayment, buybacks, and acquisitions.
Current Ratio
The current ratio measures a company's ability to pay short-term obligations by dividing current assets by current liabilities. A ratio above 1.0 indicates the company has more short-term assets than liabilities, suggesting adequate liquidity.
Quick Ratio (Acid Test)
The quick ratio, also known as the acid-test ratio, measures a company's ability to meet short-term obligations using only its most liquid assets. It excludes inventory from current assets, providing a more conservative view of liquidity than the current ratio.
Inventory Turnover
Inventory turnover measures how many times a company sells and replaces its inventory during a period. A higher turnover indicates efficient inventory management and strong demand, while low turnover may signal overstocking or weak sales.
