Margin Maker

COGS & Ending Inventory

Goods Available for Sale is a fixed pool. Every dollar either stays on the Balance Sheet as Ending Inventory or hits the Income Statement as COGS. Drag the warehouse stack and watch margin move.

Level 1 — Margin Mandate

Feel the inverse: higher Ending FG → lower COGS.

Level 2 — The Squeeze

Hit a tighter Wall Street margin under pressure.

Level 3 — Warehouse Flood

Abnormal spoilage shrinks the pool before allocation.
