Days working capital definition

What is Days of Working Capital?

Days working capital states the number of days required for a business to convert its working capital into cash. Thus, a higher days working capital figure means that a firm will require more days to realize cash from its working capital. A firm that requires fewer days to do so has a reduced need for financing, since it is making more efficient use of its working capital.

Working capital is all current assets minus all current liabilities, which are classified as such on the balance sheet. A positive working capital balance indicates that a business can pay for its immediate obligations, while a negative balance indicates that it will require extra financing in order to pay its bills on time. Businesses in the latter situation frequently use a line of credit to fund working capital shortfalls over the short term.
