A founder gets two quotations for a part. The first quotes a unit price that seems reasonable. The second is nearly double, plus a tooling charge that looks like a mistake.
He cannot compare them because nobody explained that they are quoting different things. One is a lower volume process with no tooling and a higher unit cost. The other has a one off tool and a much lower price per part.
At the quantity he will actually buy over two years, the expensive quote is considerably cheaper. He has no way of knowing that, so he chooses the one with the small number.
What makes up a manufactured part price
Four components. Material, the process time per part, the setup cost for a run, and any tooling, which is a one off spread across everything ever made with it.
Component 1: material
Frequently the smallest part of a low volume price and the largest part of a high volume one, which is why the shape of the price changes so much with quantity.
Component 2: process time per part
The actual machine or labour time. This is the number that improves with volume through efficiency rather than through arithmetic.
Component 3: setup per run
A fixed cost incurred every time a run starts, regardless of size. This is what creates a minimum order quantity in the first place.
Component 4: tooling
A one off. Used across every order made with it, which means it is not a unit cost at all and should never be compared as one.
A worked example
Suppose tooling is a fixed one off, and a part costs a low unit price once that tooling exists. At fifty parts the tooling dominates completely and the effective price per part looks extraordinary.
The same example at a real quantity
At five thousand parts the same tooling is a small addition to each unit, and the total cost is far below the alternative process that needed no tooling at all.
Why the crossover point matters most
There is a quantity at which the two approaches cost the same. A manufacturer who calculates it for the buyer is doing the most useful thing available.
Why a small first order is misleading
A buyer testing the market with a small run pays the worst possible unit price, and should be told plainly that it is not indicative of production pricing.
Why the second order changes everything
Tooling already paid, setup amortised over a known process. Buyers who understand this plan their purchasing very differently.
Why the minimum exists
Not as an obstacle but as the point below which the price stops being meaningful, which is the ground in minimum order questions manufacturers answer daily.
Who owns the tooling
A significant question that buyers do not think to ask, and which determines whether they can take the work elsewhere later.
Why lead time interacts with all of it
Tooling takes time to produce before any part is made, which is the ground in lead time questions that decide which supplier wins.
Show the arithmetic at the enquiry
An assistant that asks the realistic annual quantity, explains that tooling is a one off rather than a unit cost, shows the effective price at several volumes and identifies the crossover point lets a founder compare two quotations that currently cannot be compared at all. The same fixed against running cost distinction appears in running cost questions before installing a pool and how much does it cost to run an ai. See pricing, run the numbers on the chatbot ROI calculator, and the sector view sits under manufacturing.
