How the Sitewide Sale Profit Calculator works
A sitewide discount applies to products that were selling perfectly well at full price, which is the cost that never appears in the sale report. Revenue rises, contribution falls, and only one of those shows up in the headline.

Frequently asked questions
Do sitewide sales work?
They reliably lift revenue and frequently reduce contribution. Whether the trade is worth it depends on margin, the volume uplift and what the sale is actually for.
What is the alternative?
Targeted discounts on specific categories or slow movers, which achieve the stock objective without discounting the products that needed no help.
When is a sitewide sale right?
When the objective is customer acquisition or clearing broad excess stock, and the volume genuinely arrives. As a revenue-target tool it usually costs more than it earns.
How do I limit the damage?
Exclude bestsellers and new arrivals, set a minimum spend, and hold the sale short. Each reduces the share of the discount that goes to sales you already had.
