Calculate technician efficiency from jobs completed, actual hours worked, and standard time per job, or select an explicit inverse solve. Use matching work/time records and one standard per job (or equivalent jobs).

Earned standard labor time divided by actual labor time for the same work. Use one shared standard per job or equivalent jobs. A day means 24 elapsed hours, not a work shift. This ratio does not measure work quality or attendance.

Technician Efficiency Formula

Technician efficiency compares earned hours to actual hours worked.

TE = (J × ST / AH) × 100

Rearranged formulas:

J = (TE / 100) × AH / ST
AH = (J × ST) / (TE / 100)
ST = (TE / 100) × AH / J
  • TE = technician efficiency percentage
  • J = jobs completed
  • ST = standard time per job
  • AH = actual hours worked

Time values must use the same base unit. The calculator converts minutes and days to hours before calculating. Standard time should represent the allowed labor time for one job or equivalent job. A day is 24 elapsed hours, not an assumed shift. Efficiency is distinct from utilization of paid hours.

Example

If a technician completes 8 jobs, each with a standard time of 1.5 hours, the earned time is 12 hours. If the technician worked 10 actual hours, efficiency is:

TE = (8 × 1.5 / 10) × 100 = 120%

A 120% result means earned standard time is 1.2 times actual labor time. It does not by itself establish quality, safety or overall employee performance.
