Document Control Cost at 29% share of documents revised per year: a worked example

Suppose share of documents revised per year falls to 29%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the yearly cost of maintaining controlled engineering and quality documents under formal revision control.

The inputs for this scenario

  • Controlled documents under management: 3,500 documents (held at the documented default)
  • Annual upkeep cost per controlled document: 45 $/doc/yr (held at the documented default)
  • Share of documents revised per year: 29 % (the input this scenario stresses; the baseline uses 40)
  • Fixed document-control system fee: 18,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Annual cost = controlled documents x maintenance cost x revision share + system fee.
  • Total document control cost works out to 63,675 $ at these inputs, and this is the headline figure for the scenario.
  • Document control cost per unit works out to 18.19 $ / piece at these inputs.
  • Variable document control cost works out to 45,675 $ at these inputs.
  • Fixed document control cost adder works out to 18,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of documents revised per year sits at 40% and the headline result is 81,000 $, this scenario comes in 21.39% below the baseline at 63,675 $.
  • It computes total annual document-control cost as documents x upkeep rate x revision share plus a fixed system fee, and divides by document count for a per-document cost. 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 document control cost: 63,675 $ (headline result)
  • Document control cost per unit: 18.19 $ / piece
  • Variable document control cost: 45,675 $
  • Fixed document control cost adder: 18,000 $
