Manufacturing Cost Accounting & Finance worked example

Labor Variance at 12% setup, handling, and allowed-delay factor: a worked example in manufacturing cost accounting & finance

This scenario runs the labor variance calculation on the strong side: 12% setup, handling, and allowed-delay factor, with every other input held at its documented default. Use it when labor variance in manufacturing cost accounting and finance is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Direct-labor units to produce: 120 units (unchanged)
  • Standard labor output rate: 12 units / min (unchanged)
  • Setup, handling, and allowed-delay factor: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base labor variance time = labor variance workload รท labor variance completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required labor variance time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base labor variance time.
  • At this operating point the engine returns 12 % for labor variance allowance applied.
  • At this operating point the engine returns 12 pieces / min for labor variance completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and allowed-delay factor sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when setting or auditing labor standards before comparing them to actual clocked hours for variance reporting. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required labor variance time: 11.2 hr (headline result)
  • Base labor variance time: 10 hr
  • Labor variance allowance applied: 12 %
  • Labor variance completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Labor Variance calculator, which recalculates instantly and can be shared with the inputs intact.
