Free technician calculator

Automotive technician efficiency calculator.

Enter flagged hours, actual job hours, and available hours to calculate three different shop-performance measurements without mixing up the formulas.

Calculate your percentages

Use one repair, one day, one week, or an entire pay period—as long as every input covers the same period.

Labor hours produced or sold.
Hands-on or tracked repair time.
Total hours available to work.

Technician efficiency formula

Efficiency = flagged hours ÷ actual job hours × 100

If 3.0 labor hours are flagged and the work takes 2.5 actual hours, efficiency is 120%. A result above 100% means the produced labor time was greater than the time spent on the job.

Efficiency is not the same as productivity

MeasurementFormulaWhat it describes
EfficiencyFlagged ÷ job hoursHow produced labor compares with actual repair time
ProductivityFlagged ÷ available hoursHow much of the available day became produced labor
UtilizationJob hours ÷ available hoursHow much available time was spent working on jobs

How to use the result

  • Compare the same type of work and the same length of time.
  • Track parts, approval, dispatch, training, and equipment delays separately.
  • Review trends instead of judging one difficult repair.
  • Never trade correct diagnosis, safe repairs, documentation, or final verification for a higher percentage.
Remember: These calculations describe time—not repair quality. Shop definitions can vary, so confirm which hours your workplace includes in each measurement.

Keep the repair orders behind the percentage

RoTracker records the flagged hours, repair-order details, dates, and notes behind your weekly and pay-period totals.
