Working Capital
Working capital is current assets minus current liabilities, describing the net resources committed to or available for the short-term operating cycle.
What is Working Capital?
Current assets commonly include cash, receivables and inventory. Current liabilities commonly include supplier balances and other obligations due within the current classification period. Working capital is a balance-sheet amount measured at a point in time.
For an ecommerce store, stock purchases, settlement delays and supplier payment terms affect how resources move through the operating cycle. The amount helps describe short-term funding structure, but it is not the same as the cash immediately available in the bank.
Working capital = Current assets − Current liabilities
Use values from the same balance-sheet date and classification basis. Operating working capital is a narrower management measure that often excludes cash and financing items; label that version separately.
Positive working capital, limited cash
A store has $15,000 cash, $10,000 receivables and $35,000 inventory: $60,000 of current assets. Current liabilities are $42,000. Working capital is $18,000, but only $15,000 is already cash. Paying every current liability immediately would require more than the present bank balance.
How to interpret it
Positive working capital indicates that the stated current assets exceed current liabilities. It does not show when receivables will be collected or whether inventory can be sold promptly at its recorded value. Asset quality and payment dates determine how much protection the balance provides.
Growth can increase operating funding needs. More stock may be purchased before customers pay, while supplier terms remain unchanged. This can absorb cash even if product margins and reported profit are healthy.
A cash purchase of inventory illustrates the difference between the total and its composition. Cash falls and inventory rises by the same amount, so total working capital may initially be unchanged even though liquidity becomes less immediate.
Negative working capital can signal pressure, but some businesses collect customer cash before paying suppliers and operate with that structure. Interpretation requires the timing model, inventory quality and ability to meet obligations; the sign alone is not a complete diagnosis.
Common mistakes
Treating the entire balance as spendable cash
Inventory and receivables must be converted into cash before they can pay a bill. Their timing can matter more than the total.
Confusing an amount with a ratio
Working capital is a currency amount. The current ratio divides current assets by current liabilities and answers a related but different question.
