Fastener Manufacturing & Thread Rolling worked example

Cost Per Thousand Fasteners at 120% yield, scrap, or markup factor: a worked example

What does the result look like when yield, scrap, or markup factor reaches 120%? The full calculation is worked below with real intermediate numbers. Use it when quoting screws, bolts, nuts, studs, rivets, pins, washers, or assorted fasteners in the common dollars-per-thousand format.

The inputs for this scenario

  • Order volume in 1,000-piece blocks: 50 1,000 pieces (unchanged)
  • Quoted price per 1,000 fasteners: 38 $ / 1,000 pieces (unchanged)
  • Yield, scrap, or markup factor: 120 % (raised for this scenario; the documented default is 104)
  • Fixed lot charges (setup, tooling, freight): 275 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Lot cost = thousand-piece blocks × cost per thousand × factor + fixed lot charges) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,547 $ for total lot cost from cost-per-thousand, the number this scenario is built around.
  • At this operating point the engine returns 50.95 $ / 1,000 pieces for average cost per 1,000-piece block.
  • At this operating point the engine returns 2,272 $ for variable cpm cost.
  • At this operating point the engine returns 275 $ for fixed lot charges.

How this compares with the baseline

  • Against the tool's baseline example, where yield, scrap, or markup factor sits at 104% and the headline result is 2,251 $, this scenario comes in 13.17% above the baseline at 2,547 $.
  • A figure at this level is achievable when yield, scrap, or markup factor is genuinely sustained, not just peaked for a shift. The single percentage factor lumps yield, scrap and markup together — separate them if you need to see true material loss versus added margin.
