FormulaAverage hours = v.first_hours*Math.pow(v.units,Math.log(v.learning/100)/Math.log(2)) ; Total hours = v.first_hours*Math.pow(v.units,1+Math.log(v.learning/100)/Math.log(2)) ; Labor budget = v.first_hours*Math.pow(v.units,1+Math.log(v.learning/100)/Math.log(2))*v.hourly

How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "first_hours": 100,
  "units": 8,
  "learning": 80,
  "hourly": 30
}

Accuracy and scope

Cumulative-average learning model: average effort falls by the supplied factor each doubling. Not an individual-unit curve or empirical forecast; assumes stable repetition.
