The Contribution Margin Analyzer

Analyse contribution margin across these products and tell me where the
real profit is.

Products with price, variable cost, and volume: [PASTE THE DATA]
Total fixed costs (if allocating): [AMOUNT OR "KEEP SEPARATE"]

Show:
1. Contribution margin per unit and % for each product
2. Total contribution by product (margin × volume) — the profit-dollar
   view
3. Which products look attractive per unit but don't move the needle, and
   vice versa
4. Contribution margin per unit of the constraining resource, if one
   exists: [NAME THE CONSTRAINT OR "NONE"]
5. What this says about where to push sales effort

The lesson I want: high margin % is not the same as high profit
contribution — make that visible.
