Why there is no single "average" rate
Search for an average diesel shop labor rate and you will find many numbers from surveys, forums and vendor blogs. They rarely agree, because they mix different kinds of shops:
- Dealers, independent shops, mobile services and fleet in-house shops.
- Large metro areas and rural areas, where costs differ.
- Light, medium and heavy-duty work, roadside calls and scheduled maintenance.
- Posted door rates versus what is actually collected after discounts.
No federal agency collects and publishes shop labor rates for diesel repair. This guide uses official data only, so it does not give you a national average rate. Instead it shows the official wage data that sets your largest cost, and how to turn your own costs into a rate. If you see a survey figure, check who was surveyed, when, and whether it is a posted rate or an effective rate.
What the official wage data says
The U.S. Bureau of Labor Statistics Occupational Outlook Handbook reports for diesel service technicians and mechanics:
- Median pay, May 2025: $61,770 per year, or $29.70 per hour.
- Lowest 10 percent: earned less than $44,530.
- Highest 10 percent: earned more than $88,740.
- Jobs in 2025: about 316,000.
- Outlook: employment projected to grow 4 percent from 2025 to 2035, with about 24,400 openings each year on average.
BLS also reports median wages by industry for May 2025, including $60,330 in automotive repair and maintenance, $59,820 in truck transportation, and $71,460 in local government, excluding education and hospitals. Wages also vary by state and metro area, and the BLS Occupational Employment and Wage Statistics program publishes local figures.
These are wages paid to employees. They are not shop rates. A shop rate has to cover the technician's wage plus everything else it costs to put that technician in front of a truck.
From wage to labor rate: what the rate must cover
A labor rate pays for:
- Technician pay: wages, overtime and bonuses.
- Payroll costs: employer payroll taxes, workers' compensation and benefits.
- Unbilled time: training, cleanup, waiting on parts, travel, comebacks.
- Overhead: rent or service truck costs, insurance, tools, diagnostic software, utilities, office staff and shop software.
- Profit: money left to reinvest and to carry the business through slow months.
Unbilled time is the factor shops underestimate most. If a technician is paid for 40 hours but bills 28, every billed hour has to carry the cost of 40 paid hours.
A simple way to calculate your rate
- Add up annual costs: all technician pay and payroll costs, plus all overhead, for the past 12 months or your budget.
- Estimate billable hours: technicians multiplied by paid hours, multiplied by the share of time that is actually billed. Use your own records, not a guess.
- Divide: total costs divided by billable hours is your break-even labor rate.
- Add profit: set the rate above break-even by the margin you need.
- Compare with the market: call around, ask customers what they pay elsewhere, and decide where you want to be.
Example with illustrative numbers only: a shop with total annual costs of $600,000 and 6,000 billed hours breaks even at $100 per hour before profit. If its technicians only bill 5,000 hours, break-even rises to $120. The same shop, same costs, needs a very different rate depending on how much paid time it bills.
Posted rate versus effective rate
Your posted rate is what you charge per hour. Your effective labor rate is what you actually collect per hour worked, after flat-rate jobs, discounts and unbilled time. Track both. A shop with a high posted rate can still lose money if its effective rate is low. See how to calculate effective labor rate and effective labor rate.
Rates for different kinds of work
Many diesel shops use more than one rate:
- Standard shop rate for scheduled repairs in the bay.
- Mobile or field rate, often with a service call charge, for work at the customer's location. See how much should I charge as a mobile mechanic.
- After-hours and emergency rates for nights, weekends and holidays. See after-hours rates for mobile mechanics.
- Diagnostic rate for electrical and engine diagnosis.
- Contract rates for fleets with committed volume. See fleet maintenance contract pricing.
Whatever you choose, publish the rates to customers before they approve work, and apply them consistently.
Overtime affects your cost
If you pay technicians overtime for night and weekend calls, that work costs you more per hour. Under the Fair Labor Standards Act, the U.S. Department of Labor says covered nonexempt employees must receive overtime pay of at least one and one-half times their regular rate for hours over 40 in a workweek. Price after-hours work so the extra pay is covered.
How often to review your rate
Review your rate at least once a year, and sooner when:
- Technician wages rise to keep or attract staff.
- Insurance, rent or fuel costs change.
- Your billed hours drop.
- You add a service truck, a technician or new equipment.
Small, regular increases are usually easier for customers to accept than a large jump after years without change. Tell fleet customers in writing ahead of time.
How to research local rates without guessing
Official data will not tell you what nearby shops charge, so gather it yourself, carefully:
- Ask new fleet customers what they pay their current vendors for shop, mobile and after-hours work.
- Read rate sheets that fleets share with you during bids.
- Note what dealers in your area post, since many fleets compare against them.
- Record the date and the kind of work for every figure, because rates change.
Treat these numbers as a range, not a target. A shop with faster response, better paperwork or rare skills can charge above the range and keep customers. A shop that competes only on price usually ends up with the customers who pay slowest.
Explaining your rate to customers
Fleet managers compare invoices, not rate sheets. A higher hourly rate with accurate labor times, complete repair lines and fewer comebacks often costs the fleet less per repair than a cheap rate with padded hours. When you discuss price, talk about total cost per job, response time and how quickly trucks get back on the road. Show examples from your own invoices, with the customer's permission where needed.
Labor rate and technician pay
Your rate also decides what you can pay. BLS reports that the highest 10 percent of diesel technicians earned more than $88,740 in May 2025. If you want to hire and keep experienced technicians, your rate must leave room for pay toward the upper part of the range, plus training and tools. A rate set too low often shows up later as turnover, which costs far more than a rate increase.
Separate rates or one blended rate?
Some shops use one rate for everything because it is simple to explain. Others charge more for diagnostics, electrical work or field service because those jobs take more skill or more unbilled time. Either approach can work. Whichever you choose, check each year whether every kind of work is earning its share, using your own billed and worked hours.
Common mistakes
- Copying a competitor's rate without knowing your own costs.
- Using paid hours instead of billed hours in the calculation.
- Forgetting unbilled travel time on mobile jobs.
- Ignoring overtime when pricing after-hours work.
- Never raising rates.
