What is working capital?

Working capital equals current assets minus current liabilities. It represents the liquid buffer available to fund day-to-day operations. A positive figure means assets exceed near-term obligations; a negative figure signals potential liquidity stress.

What is a healthy level of working capital?

There is no single ideal amount — it depends on revenue size and industry. The current ratio (assets / liabilities) is a more comparable measure: 1.5 to 3.0 is considered healthy for most businesses. Very low or negative working capital may require immediate attention.

How does the current ratio differ from the quick ratio?

The current ratio includes all current assets, including inventory. The quick ratio excludes inventory because it can take time to sell and may realize less than book value in a downturn. The quick ratio is the stricter, more conservative test of short-term solvency.

Can working capital be negative?

Yes. Negative working capital means current liabilities exceed current assets. For capital-intensive businesses or retailers with very fast inventory turns (like grocery chains), this can be managed — but for most companies it signals that short-term obligations outpace liquid resources.

Where do I find these numbers?

All inputs come from the balance sheet (statement of financial position). Current assets and current liabilities each have their own subtotals; inventory is listed as a line item within current assets.
