Trim Loss Calculator at 110% share of loss charged to this job: a worked example

What does the result look like when share of loss charged to this job reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when flash loss, trim loss, sprue cutoff, or crop loss changes material usage and quote cost.

The inputs for this scenario

  • Flash and trim scrap weight: 620 lb (unchanged)
  • Material cost per pound: 1.35 $ / lb (unchanged)
  • Share of loss charged to this job: 110 % (raised for this scenario; the documented default is 100)
  • Fixed trimming and disposal cost: 180 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total trim loss calculator = trim or flash loss weight × material cost per weight unit × loss charged to this job + fixed trimming or disposal cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,101 $ for total trim loss calculator, the number this scenario is built around.
  • At this operating point the engine returns 1.78 $ / piece for trim loss cost per weight unit.
  • At this operating point the engine returns 921 $ for variable trim loss calculator.
  • At this operating point the engine returns 180 $ for fixed trimming or disposal cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of loss charged to this job sits at 100% and the headline result is 1,017 $, this scenario comes in 8.23% above the baseline at 1,101 $.
  • A figure at this level is achievable when share of loss charged to this job is genuinely sustained, not just peaked for a shift. It values trim at full material cost; if your scrap has meaningful recovery or remelt value, the net loss is lower, so subtract recovered value separately to get a true net figure.
