Document Control Cost at 46% share of documents revised per year: a worked example

Push share of documents revised per year up to 46% and the picture changes. This example computes every intermediate figure at that operating point. Use it to budget document-control staffing and platform spend against the size of your controlled library.

The inputs for this scenario

  • Controlled documents under management: 3,500 documents (unchanged)
  • Annual upkeep cost per controlled document: 45 $/doc/yr (unchanged)
  • Share of documents revised per year: 46 % (raised for this scenario; the documented default is 40)
  • Fixed document-control system fee: 18,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Annual cost = controlled documents x maintenance cost x revision share + system fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 90,450 $ for total document control cost, the number this scenario is built around.
  • At this operating point the engine returns 25.84 $ / piece for document control cost per unit.
  • At this operating point the engine returns 72,450 $ for variable document control cost.
  • At this operating point the engine returns 18,000 $ for fixed document control cost adder.

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 11.67% above the baseline at 90,450 $.
  • 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. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
