KPI guide
Repair Shop KPIs
diesel & truck shops
The metrics owners actually use to run margin: efficiency, parts gross, profit per job, and utilization — with formulas and free calculators.
Summary
Repair shop KPIs only help when they are current. Month-end spreadsheets show what already happened. Shops that improve margin track billed vs clocked hours, parts margin on open jobs, and gross profit per repair order while the truck is still in the bay.

Core repair shop KPIs
| KPI | Formula | Why it matters | Tool |
|---|---|---|---|
| Technician efficiency | Billed hours ÷ clocked hours | Shows how much logged time becomes billable labor. Gaps often mean untracked time, comebacks, or waiting on parts. | Calculator |
| Parts margin | (Parts sell − parts cost) ÷ parts sell | Parts are a large share of revenue on heavy-duty jobs; margin leaks when cost is not on the RO. | Calculator |
| Gross profit per RO | Labor gross + parts gross − job overhead | Tells you if the repair order was worth the bay time before you repeat the same pricing mistake. | Calculator |
| Bay utilization | Billed hours ÷ available bay hours | Empty bays with busy techs (or the reverse) point to dispatch and scheduling issues. | — |
| Effective labor rate | Labor revenue ÷ clocked hours | Blends your posted rate with efficiency — what you actually collect per hour paid. | Calculator |
