How to set your auto repair shop labor rate
Step 1: Add up what labor has to pay for
Labor income has to cover three things:
- Overhead: rent, utilities, insurance, equipment payments, software, advertising, and pay for anyone who isn't a tech (service writer, office).
- Tech pay, plus burden: wages plus payroll taxes, workers' comp and benefits. A rough rule is wages × 1.15; use your real number if you know it.
- Profit. Not what's left over by accident — a target you set.
Your parts gross profit (parts sales minus parts cost) helps pay overhead, so subtract it. What's left is what labor must bring in.
Step 2: Count the hours you actually bill
This is where most shops fool themselves. You pay techs for every hour they're in the building, but you only bill for hours on repair orders. The ratio is your billed-to-paid percentage.
Billed hours per month = techs × hours paid per week × 4.33 × billed-to-paid %.
Step 3: Divide
Break-even rate = what labor must bring in ÷ billed hours.
Target rate = break-even ÷ (1 − profit %).
A worked example
A two-tech shop with these numbers:
| Monthly overhead | $14,500 |
| Parts gross profit | $4,000 / month |
| Techs | 2, paid $28/hr, 40 hrs/week |
| Billed vs. paid | 85% |
| Profit target on labor | 20% |
- Paid hours: 2 × 40 × 4.33 = 346.4 hours a month.
- Billed hours: 346.4 × 85% = 294.4.
- Tech pay with burden: 346.4 × $28 × 1.15 = $11,154.
- Labor must cover: $14,500 + $11,154 − $4,000 = $21,654.
- Break-even: $21,654 ÷ 294.4 ≈ $73.54/hr.
- Target for 20% profit: $73.54 ÷ 0.8 ≈ $91.93/hr.
If the local market supports more than that, great — the difference is extra profit or room to pay techs better. If your posted rate is below break-even, every hour you bill loses money. Plug your own numbers into the labor rate calculator.
Step 4: Check your effective labor rate
Effective labor rate = labor sales ÷ hours billed. If you post $140 an hour but your effective rate is $112, something is leaking: discounts, free diagnosis, warranty comebacks, or jobs billed under book time.
Improving billed hours is often worth more than raising the rate. Going from 75% to 90% billed on two techs adds roughly 52 billable hours a month — without changing a single price.
Step 5: Raise rates without losing customers
- Raise in small steps, once or twice a year, instead of one big jump.
- Make the value visible: photos of the problem, a clear estimate, a call when the car is ready.
- Price parts with a matrix so small parts carry more margin — see the parts markup calculator.
- Charge for diagnosis. It's skilled work and customers expect to pay for it.
Questions
What is a good labor rate for an auto repair shop?+
One that covers your costs and leaves a profit at the hours you actually bill. Local averages are useful as a sanity check, but rent, pay and efficiency differ so much between shops that copying a number is risky.
Should diagnosis be charged at the labor rate?+
Yes. Diagnostic time is skilled labor. Many shops charge a set diagnostic fee (often one hour) and credit part of it if the customer approves the repair.
Is a higher labor rate bad for business?+
Not by itself. Customers react to surprises more than to rates. A clear estimate, photos of the problem and work done right the first time matter more than a few dollars an hour.
Set your labor rate once. Every estimate uses it.
