Cost Rollup Effort at 43% manual review share: a worked example

This worked example runs the cost rollup effort numbers for a tougher week than the baseline: 43% manual review share instead of the typical 60%. Estimates the labor and system cost of running a standard-cost BOM rollup cycle.

The inputs for this scenario

  • BOM levels rolled: 40 levels (held at the documented default)
  • Cost per level processed: 180 $ / level (held at the documented default)
  • Manual review share: 43 % (the input this scenario stresses; the baseline uses 60)
  • System and audit overhead: 1,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rollup effort = BOM levels x cost per level x manual review share% + system overhead.
  • Total cost rollup effort cost works out to 4,596 $ at these inputs, and this is the headline figure for the scenario.
  • Cost rollup effort cost per unit works out to 115 $ / piece at these inputs.
  • Variable cost rollup effort cost works out to 3,096 $ at these inputs.
  • Fixed cost rollup effort adder works out to 1,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where manual review share sits at 60% and the headline result is 5,820 $, this scenario comes in 21.03% below the baseline at 4,596 $.
  • Use it when budgeting an annual standard-cost refresh, scoping a costing or ERP project, or building the case to automate exception handling. 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

  • Total cost rollup effort cost: 4,596 $ (headline result)
  • Cost rollup effort cost per unit: 115 $ / piece
  • Variable cost rollup effort cost: 3,096 $
  • Fixed cost rollup effort adder: 1,500 $
