Define Working Capital?

it is calculated as the current assets minus the current liabilities.

Adding to Raja Moiz answer; Working capital is defined as the difference between current assets and current liabilities.

Current assets are the most liquid of your assets, meaning they are cash or can be quickly converted to cash.

Current liabilities are any obligations due within one year. Working capital measures what is leftover once you subtract your current liabilities from your current assets, and can be a positive or negative amount. The working capital is available to pay your company's current debts, and represents the cushion or margin of protection you can give your short-term creditors.

Working capital is the capital needed for day to day business expense, it helps in cash management by showing the cash out flow that is needed to maintain working capital.

simple definition: Working capital is the amounts of funds that business has to deploy out of its pocket in order to run its day to day operations , until payment arrives.The need of working capital arises due to time lag between cost expenditure of the business and payment arrival from the client.
