Ammunition Demand Forecast Gap Calculator with available primer and case and projectile capacity for the period of 420,000 units: a worked example

This worked example runs the ammunition demand forecast gap calculator numbers for a tougher week than the baseline: available primer and case and projectile capacity for the period of 420,000 units instead of the typical 840,000 units. Calculate demand forecast gap from available supply, forecast demand, and reference demand for a component or finished-good item.

The inputs for this scenario

  • Available primer/case/projectile capacity for the period: 420,000 units (the input this scenario stresses; the baseline uses 840,000)
  • Forecast demand for finished rounds or components: 920,000 units (held at the documented default)
  • Reference (baseline) forecast demand: 920,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Supply surplus or shortfall = available component supply or capacity - forecast demand.
  • Demand forecast gap works out to -54.35 % demand gap at these inputs, and this is the headline figure for the scenario.
  • Supply surplus or shortfall works out to -500,000 units at these inputs.
  • Available component supply or capacity works out to 420,000 units at these inputs.
  • Forecast demand works out to 920,000 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where available primer and case and projectile capacity for the period sits at 840,000 units and the headline result is -8.7 % demand gap, this scenario comes in 525% below the baseline at -54.35 % demand gap.
  • Use it during monthly or quarterly S&OP reviews, before committing powder and primer allocations, or when validating whether current capacity can cover a new government or commercial contract. 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.
