Model Retraining Cost at 110% share of full retraining scope included: a worked example

Push share of full retraining scope included up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a data science or MLOps team needs to budget model retraining after drift, process changes, new products, or sensor updates.

The inputs for this scenario

  • Planned model retraining runs: 8 runs (unchanged)
  • Compute and labeling cost per retraining run: 3,200 $ / run (unchanged)
  • Share of full retraining scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed validation and sign-off cost: 6,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable model retraining cost = planned model retraining runs × cost per retraining run × retraining scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 34,660 $ for total model retraining cost, the number this scenario is built around.
  • At this operating point the engine returns 4,333 $ / run for retraining cost per planned run.
  • At this operating point the engine returns 28,160 $ for variable model retraining cost.
  • At this operating point the engine returns 6,500 $ for fixed retraining validation adders.

How this compares with the baseline

  • Against the tool's baseline example, where share of full retraining scope included sits at 100% and the headline result is 32,100 $, this scenario comes in 7.98% above the baseline at 34,660 $.
  • It calculates total retraining cost by multiplying planned runs, per-run cost, and scope to get variable cost, then adding fixed validation and sign-off adders. 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.
