QUANTITY / UNIT PRICE
≈25%

Same drawing, material and finish · typical, varies by part
Relative to one fixed setup at 200 pcs.
Setup is only part of the unit cost, so the unit price falls less than the setup share.
Material grade and stock diameter affect material use and cost.
The machining time needed for each part contributes to its cost.
Tighter requirements can add machining and inspection work.
The specified finish adds supplier processing and handling costs.
Figures are typical, not a price list. Your quotation shows the actual unit price for each quantity.
