Change in non-cash working capital, often reported simply as the change in working capital, is the total cash effect of movements in a company's operating current assets and liabilities, excluding cash itself and debt, during a period. It combines the individual adjustments for receivables, inventories, prepaid assets, payables, accrued liabilities, and other operating items in the operating section of the cash flow statement.

A negative figure means the company tied up cash in working capital, for example by building inventory or extending more credit to customers. A positive figure means working capital released cash.

Under ASC 230's indirect method, companies reconcile net income to operating cash flow by adding back noncash charges and then adjusting for changes in operating assets and liabilities. Many filers present those changes as a group under a subheading such as "changes in operating assets and liabilities." The XBRL element IncreaseDecreaseInOperatingCapital represents the total change across the assets and liabilities used in operations, but most companies report only the individual lines, so the total is usually calculated by adding them up.

Cash and short-term debt are left out on purpose. Cash is the result being explained, and borrowings are financing activities, so including either would double count. For that reason the figure is not the same as the change in working capital on the balance sheet, which also includes cash and the current portion of debt. Acquisitions, divestitures, and currency translation create further gaps between the balance sheet movement and the cash flow figure.

This line is central to cash flow analysis. It explains most of the difference between earnings and operating cash flow in a typical year, and it is a required input to free cash flow models. A growing company usually consumes working capital, so a persistently negative figure is normal during expansion. A sudden positive swing, when earnings are flat, often comes from collecting receivables or stretching payables and may not repeat.
