Fiber Usage Cost at 68% web yield: a worked example

Suppose web yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the delivered fiber cost embedded in a nonwoven run from charged weight, price and web yield.

The inputs for this scenario

  • Fiber consumed: 2,500 kg (held at the documented default)
  • Delivered fiber price: 2.4 $/kg (held at the documented default)
  • Web yield: 68 % (the input this scenario stresses; the baseline uses 94)
  • Blending and lay-down charge: 180 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fiber cost = fiber consumed x delivered price x web yield% + blending charge.
  • Total fiber usage cost works out to 4,260 $ at these inputs, and this is the headline figure for the scenario.
  • Fiber usage cost per unit works out to 1.7 $ / piece at these inputs.
  • Variable fiber usage cost works out to 4,080 $ at these inputs.
  • Fixed fiber usage cost adder works out to 180 $ at these inputs.

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 26.8% below the baseline at 4,260 $.
  • It calculates total fiber usage cost as fiber consumed times delivered price times web yield, plus a fixed blending charge, and derives the per-kilogram fiber burden. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total fiber usage cost: 4,260 $ (headline result)
  • Fiber usage cost per unit: 1.7 $ / piece
  • Variable fiber usage cost: 4,080 $
  • Fixed fiber usage cost adder: 180 $
