Working Capital: What Current Assets and Liabilities Show
Working capital is current assets minus current liabilities. This article explains what the figure measures, how to read it from a balance sheet, and what it does not tell you.
Working capital is one of the most frequently cited figures in company analysis. The formula is simple: current assets minus current liabilities. What those two lines contain, and what the result actually tells you, is less obvious.
What counts as current
Current assets are resources the company expects to convert to cash within twelve months: cash and cash equivalents, short-term investments, trade receivables, and inventories. Current liabilities are obligations due within the same period: trade payables, short-term borrowings, and accrued expenses.
The twelve-month boundary is a convention, not a law of nature. A company with a long production cycle — shipbuilding, for example — may classify items as current that will not move for eighteen months.
What the figure measures
A positive working capital means current assets exceed current liabilities. The company has a buffer: if all short-term creditors demanded payment today, the liquid assets would cover them. A negative figure means the opposite.
Neither is automatically good or bad. Retailers often run negative working capital because customers pay immediately and suppliers are paid later — the business is funded by its creditors in a stable, repeating cycle. A manufacturer with large inventories and slow-paying customers may show high positive working capital but still face a cash squeeze if the inventories cannot be sold quickly.
What it does not measure
Working capital is a snapshot, not a flow. It does not show whether the company generated cash last quarter or whether it will next quarter. A company can improve its working capital figure by delaying supplier payments — that is a financing decision, not an operational improvement.
It also does not distinguish between liquid and illiquid current assets. Receivables from a single large customer who is slow to pay look the same on the balance sheet as cash.
Where to find the data
The figures come from the balance sheet, which is part of the annual report and, for listed companies, the quarterly filing. In Hungary, annual reports are filed with the Company Registry (Cégbíróság) and published on e-cegjegyzek.hu. For US-listed companies, the 10-K and 10-Q filings on SEC EDGAR contain the balance sheet.
