Working capital is a simple but powerful measure of a business’s financial health. It is the difference between current assets and current liabilities. In other words, it shows what is left when a business’s short-term debts are taken away from its short-term resources such as cash, stock and money owed by customers.

If the result is positive, the business has money available to cover day-to-day operations. If it is negative, the business may struggle to meet upcoming bills or need to rely on borrowing.

Why is working capital so important? First, it gives a clear picture of liquidity. A profitable business can still fail if it runs out of cash to pay suppliers, wages, or rent. By keeping a close eye on working capital, owners can see whether they have enough resources to keep the business running smoothly.

Second, working capital affects flexibility. A business with strong working capital can take opportunities such as bulk-buying stock at a discount or investing in new projects. A business with weak working capital may be forced to delay decisions or turn down growth opportunities because it cannot afford the risk.

Third, lenders and investors often look at working capital when deciding whether to support a business. A healthy balance suggests stability and good management, while a weak position may raise concerns.

Improving working capital does not always mean cutting costs. It can involve speeding up customer payments, negotiating longer terms with suppliers, or keeping a closer watch on stock levels. Even small changes can make a big difference to cash flow.

In short, working capital is about making sure a business can meet today’s needs while staying ready for tomorrow’s opportunities.
