Board Foot Yield at 68% target grade-yield rate: a worked example

This worked example runs the board foot yield numbers for a tougher week than the baseline: 68% target grade-yield rate instead of the typical 95%. Estimate board foot yield for wood and paper manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Boards passing grade: 8 count (held at the documented default)
  • Total boards run through the mill: 250 count (held at the documented default)
  • Target grade-yield rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Board foot yield rate = board foot yield count ÷ total board foot yield population × 100.
  • Board foot yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Board foot yield gap to target works out to 64.8 points at these inputs.
  • Board foot yield count works out to 8 count at these inputs.
  • Total board foot yield population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target grade-yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it after grading a run, shift, or log lot to benchmark actual grade recovery against a mill target. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Board foot yield rate: 3.2 % (headline result)
  • Board foot yield gap to target: 64.8 points
  • Board foot yield count: 8 count
  • Total board foot yield population: 250 count
