Yield Loss Estimate at 3.6% insurance or treatment action threshold: a worked example

This worked example runs the yield loss estimate numbers for a tougher week than the baseline: 3.6% insurance or treatment action threshold instead of the typical 5%. Estimate yield loss percent from lost yield, expected yield, and a target or threshold loss percent.

The inputs for this scenario

  • Lost or damaged bushels: 18 bu, tons, or lb (held at the documented default)
  • Expected field yield (unaffected basis): 180 bu, tons, or lb (held at the documented default)
  • Insurance or treatment action threshold: 3.6 % (the input this scenario stresses; the baseline uses 5)

Working through the calculation

  • The calculation starts from the formula this tool documents: Yield loss percent = lost yield / expected yield x 100.
  • Yield loss percent works out to 10 % at these inputs, and this is the headline figure for the scenario.
  • Loss above threshold works out to -6.4 points at these inputs.
  • Lost yield works out to 18 count at these inputs.
  • Expected yield works out to 180 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where insurance or treatment action threshold sits at 5% and the headline result is 10 %, this scenario lands almost exactly on the baseline at 10 %.
  • Use it right after a damage event or mid-season appraisal, before deciding to replant, treat, or file an insurance claim. 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

  • Yield loss percent: 10 % (headline result)
  • Loss above threshold: -6.4 points
  • Lost yield: 18 count
  • Expected yield: 180 count
