Labeling Workload at 20% label qa and rework allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop label qa and rework allowance to 20%, then walk the calculation through step by step. Estimate labeling time for industrial AI images, events, or time-series samples using sample count, labeling rate, and QA allowance.

The inputs for this scenario

  • Samples requiring labels: 4,800 samples (held at the documented default)
  • Labeling completion rate: 6 samples / min (held at the documented default)
  • Label QA and rework allowance: 20 % (the input this scenario stresses; the baseline uses 28)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base labeling time = samples requiring labels รท labeling completion rate.
  • Required labeling time works out to 960 min at these inputs, and this is the headline figure for the scenario.
  • Base labeling time works out to 800 min at these inputs.
  • Label QA and rework allowance works out to 20 % at these inputs.
  • Labeling completion rate works out to 6 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where label qa and rework allowance sits at 28% and the headline result is 1,024 min, this scenario comes in 6.25% below the baseline at 960 min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to label qa and rework allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. A single average labeling rate hides the spread between easy and hard samples; mixed-difficulty datasets may need separate estimates per class.

Results at a glance

  • Required labeling time: 960 min (headline result)
  • Base labeling time: 800 min
  • Label QA and rework allowance: 20 %
  • Labeling completion rate: 6 pieces / min
