Die Cost Per Part at 99% usable share of rated die life: a worked example

This scenario runs the die cost per part calculation on the strong side: 99% usable share of rated die life, with every other input held at its documented default. a stamping estimator needs to amortize die build cost across projected part volume for a quote.

The inputs for this scenario

  • Parts stamped over die life: 500,000 parts (unchanged)
  • Die cost per stamped part: 0.09 $ / part (unchanged)
  • Usable share of rated die life: 99 % (raised for this scenario; the documented default is 88)
  • Die sharpening and regrind reserve: 4,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total die cost over life = parts stamped × die cost per part × die life realization + die sharpening reserve) to the inputs above produces each figure below.
  • At this operating point the engine returns 48,550 $ for total die cost per part cost, the number this scenario is built around.
  • At this operating point the engine returns 0.1 $ / piece for die cost per part cost per unit.
  • At this operating point the engine returns 44,550 $ for variable die cost per part cost.
  • At this operating point the engine returns 4,000 $ for fixed die cost per part adder.

How this compares with the baseline

  • Against the tool's baseline example, where usable share of rated die life sits at 88% and the headline result is 43,600 $, this scenario comes in 11.35% above the baseline at 48,550 $.
  • Use it when quoting a stamped part, comparing die options, or determining when a die has recovered its cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total die cost per part cost: 48,550 $ (headline result)
  • Die cost per part cost per unit: 0.1 $ / piece
  • Variable die cost per part cost: 44,550 $
  • Fixed die cost per part adder: 4,000 $
