How to use Repair Shop Work Order Capacity Calculator
- Use technician touch time rather than total vehicle dwell time.
- Count bays that are staffed and equipped for the work mix.
- Compare capacity with parts availability and promised completion windows.
Calculator guide
Understanding Repair Shop Work Order Capacity Calculator
Repair-shop throughput depends on staffed bays, productive technician minutes, job duration, first-pass repair, parts readiness, and peak intake.
Calculation method
How the calculation works
Convert scheduled repair work order resources into productive minutes, gross throughput, first-pass completed capacity, buffered design demand, utilization, staffing hours, and labor cost per completed unit. Convert staffed-bay shifts into productive minutes, divide by average active repair minutes, and apply first-pass completion before comparing demand.

Worked situations
Practical examples
- A vehicle can occupy a bay while waiting for parts.
- Diagnostic work has greater duration variability than routine service.
- A comeback consumes future capacity even when not billed again.
Better inputs
Useful tips
- Separate quick service, diagnostics, heavy repair, and inspections.
- Track bay occupancy and technician touch time independently.
- Protect capacity for rework and unplanned findings.
Before relying on the result
Limitations and common mistakes
- One work-order duration and first-pass rate are used.
- Parts delays, lift types, technician certifications, and vehicle dwell are simplified.
- The result is not a dispatch board.
Reference
Key terms
- Technician touch time
- Active labor minutes spent on the vehicle.
- Bay occupancy
- Elapsed time a vehicle occupies a service position.
- Comeback
- Repeat work caused by an unresolved or related issue.
Important note
Calculated from the entered vehicle and operating values. Actual prices, financing terms, efficiency, maintenance, insurance, taxes, and resale outcomes can differ.
Frequently asked questions
Should parts-wait time be in service minutes?
Not as technician touch time, but it may need a separate bay-occupancy constraint.
Does one bay equal one technician?
Not always; staffing and bay resources must both be feasible.
How should comebacks be modeled?
Use the first-pass completion input or a separate rework scenario.
