If you turn wrenches in southeast Michigan and you want to know whether you are being paid properly, you need two numbers: what the market pays, and what actually moves you up inside it. Most pay conversations in this trade happen on rumour and a friend’s word. Here are the real figures, and what sits behind them.
What the market pays right now
The Bureau of Labor Statistics puts the median wage for automotive service technicians and mechanics in the Detroit–Warren–Dearborn metro at $26.92 an hour, or about $56,000 a year, in its 2025 survey. The bottom ten percent sit at $17.83 an hour and the top ten percent at $39.06, which works out to roughly $81,240 a year.
Statewide Michigan runs slightly behind the metro: $26.02 median, $17.36 at the tenth percentile, $38.01 at the ninetieth. Nationally the median is $50,620 a year. So Detroit pays above the national number, and the spread between a first-year lube tech and a seasoned A-tech is roughly double.
Two things are worth reading into that spread. The first is that it is wide because this trade pays for capability, not for attendance. The second is that the ninetieth percentile figure is a wage number, and a lot of the technicians who exceed it are on flat rate, where a good week is not capped the way an hourly week is.
Flat rate is the biggest variable in your paycheck
Two technicians in the same market with the same certifications can be $15,000 a year apart because one is hourly and one is on flat rate. Flat rate pays you the book time for the job regardless of how long it took, so an efficient technician in a shop with steady car count earns well above their nominal rate, and a technician sitting in a slow bay earns below it.
The trap is that flat rate transfers the shop’s risk onto you. A slow February, a bad dispatcher, a comeback you eat — those all land on your paycheck rather than the shop’s. Before you take a flat rate seat, ask what the shop’s average technician efficiency actually is, not what the best technician hits. We wrote a longer piece on the tradeoff in flat rate versus hourly.
Certifications are the clearest lever you control
ASE certifications are the one thing that moves your rate on a schedule you can predict. Most shops in this market attach a raise to each certification, and the jump from a general technician to an ASE Master with L1 is where the biggest single step in this trade happens. If you are early and choosing where to start, the brake and electrical certifications carry the most weight per hour of study — our A5 brakes guide and A6 electrical guide are the ones people work through first.
The thing nobody tells a new technician: ask the shop whether they pay for the test, and whether the raise is written down. A verbal promise that a certification is “worth a dollar” evaporates when the manager changes.
Where the money actually goes after the bay
The wage figures above only cover people turning wrenches. The technicians who end up earning the most in this trade usually stop being technicians at some point. A strong service advisor in this market runs comfortably above the technician median once commission is counted, and a shop manager running a store with real volume can clear six figures.
That is not advice to leave the bay — plenty of A-techs earn more than a mediocre advisor and enjoy the work more. It is a note that the ceiling on the technician wage scale is not the ceiling on the trade.
What to ask before you take a job
Four questions separate a real offer from a number on a job ad.
- Hourly, flat rate, or a guarantee? If flat rate, what is the guarantee floor and how often has it been used in the last year?
- What is the shop’s car count per bay? This determines your paycheck on flat rate more than your rate does.
- What does the raise schedule look like in writing? Per certification, per year, per performance review — whichever it is, it should exist on paper.
- Who pays for tools, training and test fees? The answer varies more than people expect. Our piece on shop-provided versus tech-owned covers what is normal.
Where ARNAZ sits
We publish our ranges on our job pages rather than making candidates guess: technicians start at $22–$24 an hour, service advisors at $24–$28 an hour plus commission on services sold, and shop managers at $85,000–$160,000 base plus commission. Technician pay moves with skills and certifications from there.
We would rather you compare that to the numbers above than find out after you have taken the job. If you want to see what is open across our shops in Livonia, Taylor, Canton, Redford, Ypsilanti, Ann Arbor and Southfield, our open roles are here.
