How this calculator works

Turn minutes saved per task into weekly and yearly hours.. Define exactly what counts as the task, when timing starts and what counts as finished. Use the same definition before and after a change. If the work varies, measure several attempts rather than relying on a single unusually fast example.

Important assumptions

Record the time for a typical set of tasks before making a change. Note interruptions, complexity and quality requirements. Faster work is not a real improvement if accuracy, safety or customer experience declines.

Common mistakes to avoid

  • Mixing units or time periods.
  • Counting the same fee or tax twice.
  • Treating an estimate as a live quote or guarantee.
  • Ignoring maintenance, waste, exceptions or other costs outside the inputs.
