The formula to calculate the change in net working capital (WC) is:
\[ WC = CWC - PWC \]
Where:
Let's say the current net working capital (\( CWC \)) is $50,000, and the previous net working capital (\( PWC \)) is $40,000. Using the formula:
\[ WC = 50000 - 40000 \]
We get:
\[ WC = 10000 \]
So, the change in net working capital (\( WC \)) is $10,000.
Suppose the current net working capital (\( CWC \)) is $30,000, and the previous net working capital (\( PWC \)) is $35,000. Using the formula:
\[ WC = 30000 - 35000 \]
We get:
\[ WC = -5000 \]
So, the change in net working capital (\( WC \)) is -$5,000, indicating a negative change.
The change in net working capital is simply the subtraction of the previous net working capital from the current. It is possible for this value to be negative, in which case there is a negative change in NWC.
