Fiber Usage Cost at 99% web yield: a worked example

This scenario runs the fiber usage cost calculation on the strong side: 99% web yield, with every other input held at its documented default. A roll-goods estimator pricing a spunlaid or carded line uses it to size the fiber portion of a quote before locking margin.

The inputs for this scenario

  • Fiber consumed: 2,500 kg (unchanged)
  • Delivered fiber price: 2.4 $/kg (unchanged)
  • Web yield: 99 % (raised for this scenario; the documented default is 94)
  • Blending and lay-down charge: 180 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Fiber cost = fiber consumed x delivered price x web yield% + blending charge) to the inputs above produces each figure below.
  • At this operating point the engine returns 6,120 $ for total fiber usage cost, the number this scenario is built around.
  • At this operating point the engine returns 2.45 $ / piece for fiber usage cost per unit.
  • At this operating point the engine returns 5,940 $ for variable fiber usage cost.
  • At this operating point the engine returns 180 $ for fixed fiber usage cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where web yield sits at 94% and the headline result is 5,820 $, this scenario comes in 5.15% above the baseline at 6,120 $.
  • Use it when quoting a nonwoven order, comparing fiber suppliers or blends, or analyzing how a yield change moves material cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
