The numbers every auto repair owner should track

Tracking the right metrics allows independent auto repair shop owners to spot issues early, adjust pricing, and maintain steady cash flow without drowning in spreadsheets. Focus on these six indicators because they directly influence daily decisions about staffing, parts ordering, and customer communication. Review them weekly or monthly using data from your shop management software or accounting records.

Revenue per Job

Calculate this by dividing total revenue for a given period by the number of completed repair orders. Include all labor, parts, and fees but exclude taxes. Track it separately for different service categories such as brakes or diagnostics to reveal which work generates the most income.

• Compare month to month to detect drops that may signal weak upselling or parts shortages.
• In both the US and Canada, realistic targets fall in the range of 350 to 550 in local currency, though urban shops with higher labor rates often sit toward the upper end.
• If the figure trends low, review estimate accuracy and technician training on additional needed repairs.

Gross Margin

Determine gross margin by subtracting the cost of goods sold (parts and subcontractor work) from total revenue, then dividing the result by total revenue and multiplying by 100. Exclude direct labor costs from this calculation because they fall under operating expenses. Run the numbers separately for parts and labor where possible.

• Aim for consistent tracking by entering every invoice into your system on the same day work completes.
• Healthy ranges sit between 50 and 65 percent across most US and Canadian shops, with Canadian operators sometimes seeing slight compression from higher import duties on certain components.
• When margins slip, audit supplier pricing and consider stocking high-volume items in-house rather than ordering per job.

Close or Booking Rate

Measure this by dividing the number of repair orders opened by the number of estimates or quotes presented to customers. Count only estimates that receive a clear yes or no response within a set time frame, usually 48 hours.

• Log every estimate in a simple spreadsheet or software field to avoid relying on memory.
• Typical targets range from 70 to 85 percent, with phone quotes often lower than in-person presentations in both countries.
• Improve the rate by training advisors to explain repair urgency clearly and by following up on open estimates the next business day.

Labor Efficiency

Calculate labor efficiency by dividing billable hours posted to customer jobs by the total available technician hours in the same period. Available hours equal scheduled shop hours minus vacations and training time. Exclude diagnostic time that cannot be billed if your shop policy does not charge for it.

• Record start and stop times on every job ticket to keep data accurate.
• Strong performance usually falls between 75 and 90 percent, though Canadian provinces with stricter break rules may see slightly lower ceilings.
• Raise efficiency through better job scheduling and by reducing interruptions during active repairs.

Callback Rate

Track callback rate by dividing the number of jobs that require a return visit for the same complaint by the total number of completed jobs. Include only callbacks within 30 days and exclude new unrelated issues.

• Tag every callback in your management system with a clear reason code such as part failure or incomplete diagnosis.
• Keep the rate under 5 percent in both the US and Canada by double-checking fluid levels and test drives before vehicles leave the bay.
• When the rate climbs, review recent technician assignments and parts quality from specific suppliers.

Average Ticket

Compute average ticket by dividing total revenue by the number of unique customer visits rather than by individual repair orders, since one visit may generate multiple orders. This metric captures overall spending per customer encounter.

• Separate new customer tickets from returning ones to highlight retention strength.
• Realistic targets mirror revenue per job ranges of 350 to 550 in local currency, adjusted upward for shops that bundle maintenance packages.
• Increase the figure by offering maintenance reminders 30 days before recommended service intervals.

Review these metrics together rather than in isolation because a high average ticket paired with a low close rate often points to overly aggressive quoting. Adjust targets gradually based on your shop size, location, and customer mix rather than chasing industry averages that may not fit your operation.
