The day-to-day cushion

Working capital is what's left when you subtract what the business owes soon from what it owns that's cash or soon-to-be-cash. It funds payroll, inventory, and the gap between paying suppliers and getting paid. Positive working capital is breathing room; negative means bills could outrun available cash.

Quick FAQ

Is more working capital always better?

Up to a point. Enough to operate comfortably is essential, but a very high figure can mean cash or inventory sitting idle instead of being invested in growth.

Can a healthy business have negative working capital?

Yes — some (like fast-turn retailers) collect from customers before paying suppliers, running lean by design. Context matters; compare to your industry.
