Why you need this
A campaign starts as 'a small discount'; multiplied by quantity the loss grows. With cost fixed, the whole discount comes out of gross profit.
This tool shows sales loss and gross profit loss together; it does not assume extra volume.
How it is calculated
Discount per unit = price x discount rate. Discounted price = price - discount per unit. Sales loss = discount per unit x quantity. With cost fixed, gross profit loss equals sales loss.
How to read the result
Gross profit loss is the direct campaign cost. Offsetting it needs extra orders; this tool does not assume that lift, only the loss amount.
