Cycle time is the best KPI for an auto body shop in 2027, followed by severity ($4,768 average total cost of repair through Q3 2025, per CCC) and touch time. CCC data shows repairs with no calibrations averaging 13 days keys-to-keys, against more than 17 with multiple calibrations. Where no source publishes a benchmark, this page says so.

Answrs VerdictThe headline KPI.
Formula: Average calendar days from the date the vehicle is received to the date it is delivered, for repairs closed in the monthBenchmark: 13 days keys-to-keys with no calibrations, 15.5 with one calibration, more than 17 with multiple calibrations (CCC)Insurer view: J.D. Power puts the average for repairable vehicles at 19.3 days, down from 22.3 days a year earlierOlder target: BodyShop Business (2011): under five days for driveable vehicles, under 10 for non-driveable
Cycle time is the average calendar days from the date a vehicle is received to the date it is delivered. CCC data reported by AutoBody News shows 13 days keys-to-keys with no calibrations, 15.5 with one and more than 17 with multiple calibrations, while J.D. Power puts the insurer-side average at 19.3 days.
Go ifEvery shop; it is the one number insurers, customers and your production floor all feel

Why #1 over #2: Every other KPI on this list ends up inside the cycle-time number, which is why severity ranks behind it.

Severity (Average Repair Cost)

Answrs VerdictThe revenue-per-repair KPI.
Formula: Average repair dollars per repair order (RO)Benchmark: CCC puts the average total cost of repair at $4,768 through Q3 2025, up 1.4% year over yearRelated measure: Sales per RO = total sales divided by ROsCost trend: CCC expects the full-year 2025 increase to be below 2%
Severity is the average repair dollars per repair order. CCC puts the average total cost of repair at $4,768 through Q3 2025, up 1.4% year over year, which makes it the clearest read on whether repair complexity is reaching your invoices.

Touch Time

Answrs VerdictShows where cycle time hides.
Formula: Average billed hours produced per day per RO, for example a 20-hour job finished in four days is 5 hours per dayBenchmark: Insurers generally use four hours per day, though some have moved to five (BodyShop Business, 2011)Definition: The average duration of time each vehicle is worked on per day
Touch time is the average billed hours produced per day per repair order. BodyShop Business reported in 2011 that insurers generally use four hours per day, though some have moved to five.

Why #3 over #4: It explains idle days inside the cycle, which technician efficiency cannot show.

Technician Efficiency

Answrs VerdictThe labor-return KPI.
Formula: Efficiency % = sold hours / worked hours x 100Worked example: 10 sold hours over 8 worked hours is 125%Shop-level version: Overall productivity = total labor hours divided by total tech clock hoursBenchmark: No benchmark published in the sources cited
Technician efficiency is sold hours divided by worked hours times 100, so 10 sold hours over 8 worked hours is 125%. The sources cited publish the formula but no industry benchmark.
Go ifOwners who pay technicians flat rate and need to see the true return on each clock hour
Skip ifYou have no shop management system to capture clock hours
Why #4 over #5: It measures return on each paid clock hour, where gross profit margin only reports the month-end result.

Gross Profit Margin

Answrs VerdictThe bottom-line KPI.
Formula: Total gross profit divided by total salesIncludes: Labor, parts, paint and materials and sublet gross profit combinedNet profit: FenderBender calls net profit the ultimate KPI for any business, tracked in dollars or as a percent of total salesBenchmark: No benchmark published in the sources cited
Gross profit margin is total gross profit divided by total sales, covering labor, parts, paint and materials and sublet. FenderBender calls net profit the ultimate KPI for any business.
Go ifOwners who want one scoreboard that rolls every department together
Skip ifYou want a daily floor metric; this one is a month-end read
Why #5 over #6: It rolls every department into one number, where paint cost per hour covers only refinish.

Paint and Materials Cost per Paint Hour

Answrs VerdictThe refinish-cost KPI.
Formula: Paint and materials cost divided by paint hoursBest usage measure: Paint-only cost per paint hour, which the source calls the most reliable measure of paint usageSanity check: Paint-only cost as a share of P&M cost: below 63% or above 73% can signal misclassified costsMethod: Track paint at refinish (list) pricing rather than net of discounts so results compare to industry benchmarks
Paint and materials cost per paint hour is paint and materials cost divided by paint hours. BASF’s definitions call paint-only cost per paint hour the most reliable measure of paint usage.

Why #6 over #7: It is more actionable day to day than booth hours because it points at spending, not just capacity.

Paint Booth Hours per Day

Answrs VerdictThe capacity-use KPI.
Formula: Paint hours produced per booth per day, to show capacity utilizationBenchmark: A booth can typically produce about 300 paint hours per week (FenderBender example)Example shop: An example shop averaged 175 hours per week on one boothRelated measure: Vehicles per day per booth = ROs divided by workdays divided by paint booths
Paint booth hours per day shows capacity utilization. FenderBender notes a booth can typically produce about 300 paint hours per week, and its example shop averaged 175 hours per week on one booth.
Go ifShops with one booth that is the bottleneck for every repair
Skip ifYour booth sits idle because body work is the constraint
Why #7 over #8: It exposes the booth bottleneck, which parts margin does not touch.

Parts Gross Profit

Answrs VerdictThe parts-margin KPI.
Formula: Parts gross profit divided by parts salesCompanion ratio: Parts to labor sales = parts sales divided by total labor salesMarket signal: CCC data showed average part prices up more than 4% year over year in March and April 2025Benchmark: No benchmark published in the sources cited
Parts gross profit is parts gross profit divided by parts sales. CCC data showed average part prices up more than 4% year over year in March and April 2025, so the margin needs watching.
Go ifParts managers watching margin as prices and sourcing rules shift

Customer Satisfaction (CSI)

Answrs VerdictThe customer-verdict KPI.
Formula: The overall Customer Satisfaction Index score generated by the center’s CSI system or vendorIndustry context: J.D. Power’s 2025 claims study scored overall satisfaction at 700 on a 1,000-point scaleRepair link: Satisfaction for repairable vehicles rose 9 points as cycle times shortenedBenchmark: No shop-level CSI benchmark published in the sources cited
CSI is the overall customer satisfaction score from your CSI system or vendor. J.D. Power’s 2025 claims study scored overall satisfaction at 700 on a 1,000-point scale and found repairable-vehicle satisfaction up 9 points as cycle times shortened.
Go ifShops that depend on insurer programs and repeat customers

Why #9 over #10: It is the customer’s verdict, which complements the calibration rate’s view of repair complexity.

How we ranked these
We ranked KPIs on how directly they drive collision-shop results and how clearly industry sources define them, using CCC data reported by AutoBody News and Repairer Driven News, FenderBender, BodyShop Business, BASF and J.D. Power. We cite a benchmark only where a source states one, and several figures come from different definitions of cycle time, so compare them with care. Facts are taken from each maker's own published information; check the official site before you buy.
Questions people ask
What is the most important KPI for an auto body shop?
Cycle time is the headline KPI: the average calendar days from vehicle receipt to delivery. CCC data shows repairs with no calibrations averaging 13 days keys-to-keys.
How many KPIs should a collision shop track?
FenderBender advises focusing on three to five KPIs at a time and tracking each over a period of at least 90 days.
How is technician efficiency calculated?
Efficiency % equals sold hours divided by worked hours times 100, so 10 sold hours over 8 worked hours is 125%.
Is there a published benchmark for touch time?
BodyShop Business reported in 2011 that insurers generally use four hours per day, with some at five; treat it as a dated reference point.
