When this applies
when evaluating any product or service whose price seems structurally fixed by the industry
The takeaway
Don't accept a quoted price as a constraint — derive the theoretical floor cost from raw inputs and physics, then treat the gap between floor and market price as capturable waste.
Why it works
Decomposing a product into its raw material cost reveals how much of the price is markup, custom design, and waste rather than physics, exposing room to attack.
One level up
Treat inherited cost/assumption structures as variables to question, not fixed constraints of reality.
Where it stops holding
This stops working when the raw-material or physics floor is genuinely close to final price (i.e., the markup opportunity doesn't actually exist), or when you lack the capability to capture the gap yourself.
Detail
approach: Ask 'what is this made of' and 'what do those raw materials cost on commodity markets' rather than accepting the vendor-quoted price.
signals:- high ratio of selling price to raw material cost ('idiot index')
- quotes from suppliers that seem arbitrarily high
- multi-tier contractor markup
rationale: If materials cost is a tiny fraction of price, the rest is process/overhead/markup which is addressable, not a law of physics.
In their words
It turned out that the materials cost of a rocket was around 2% of the typical price, which is a crazy ratio for a large mechanical product.
