Interactive fully-loaded Black Friday Cyber Monday profit and loss waterfall across five product categories, running from gross list value through net revenue to contribution margin, with a returns line and dual gross and net percentage columns.

Generalized category benchmarks, not one company's results. The “% of gross” column subtracts top-to-bottom to 100%; “% of net rev” resets at net revenue and is how operators usually benchmark each line. Cells marked * are modeled where no category-level figure is published.
