The median pay is about $65,700 a year. Across everyone in the job it runs from about $46,290 at the lower end to about $93,600 at the upper end. The source is listed under Sources at the end of this page.
4 to 5 years, on the usual route, and you are paid while you train from the first day.
$1,000 to $8,800 all in for tuition, fees, exams and kit. Living costs are not counted.
No. There is no license to hold, though many employers still ask for training or a certificate.

The national median is $65,700 a year, the bottom tenth earn $46,290 or less and the top tenth $93,600 or more, in the 2025 survey. The survey figures leave out overtime, and plant shutdowns, when crews work long weeks, bring a lot of it.
$46,290 to $56,390
The bottom tenth and bottom quarter of millwrights, 2025
Apprentices usually start in this part of the range. Registered apprentice pay is a set percentage of the fully qualified rate and climbs every six months or year until you finish. You do not pay tuition for the classroom part.
$56,390 to $81,500
Half of all millwrights earn between these two figures, 2025, before overtime
Shutdown work is where the overtime is. Federal law sets overtime at time and a half for hours over 40 in a week, some union agreements pay double time, and traveling crews usually get a daily allowance for food and lodging. The other side of it is quiet stretches between jobs on the construction side of the trade.
Roughly, all in
$1,000 to $8,800
Tuition, fees, exams and kit. Not rent, food or travel
A registered apprenticeship is paid work and the classroom training is covered by the program, so the low end is a starter tool kit at around $800 and boots and safety gear at about $250. The high end adds a one year industrial maintenance certificate at a community college at $2,000 to $6,000 before you apply, plus a fuller tool set with dial indicators and a box. Most millwrights finish training with savings rather than student loans. Apprenticeship places are competitive, so the college certificate is partly a way of getting to the front of that queue.
Like the other building trades, this is a path where you can finish training with savings instead of student loans. If you do take a college course first, fill in the Free Application for Federal Student Aid, because a Pell Grant often covers a one-year certificate.
Defined benefit pension
Union millwrights build a pension from their first hour worked. It is one of the main reasons people stay in the trade.
Health and dental for the family
Funded by the hours you bank, which is why steady work matters as much as the hourly rate.
Annuity on top of the pension
Many local agreements put an extra hourly amount into a retirement account.
Travel and lodging allowance
Paid when a job sends you away from your home area.
The exact path from high school to qualified.
A paid apprenticeship, not a degree. About four years, most of it on the job.
High school diploma or an equivalency certificate
Grade 12
Shop, math and physics classes help. You normally need to be 18 and pass a physical and a drug test.
Apply to an apprenticeship
Weeks to a year of waiting
Local unions of the United Brotherhood of Carpenters run the main millwright programs, and plants and contractors run their own. Applications open in windows, not all year.

You are an employee from day one, working beside qualified millwrights.
Work plus classroom training
About 4 years
Registered apprenticeships run on a minimum of about 2,000 hours of paid work a year plus roughly 144 hours of classroom instruction. Millwright programs are usually about four years in total.
Journeyman millwright
After the hours
Finish the hours, pass the program's practical and written tests, and you are qualified. There is no state exam to sit.
Math
Alignment and layout are geometry and trigonometry, done with real numbers that have to be right.
Physics
Rigging, loads, torque and vibration. Getting this wrong hurts people.
Shop or automotive
Anything where you take machines apart and put them back working.
Drafting or blueprint reading
Every installation starts with a layout drawing.
No state issues a millwright license the way it does for electricians and plumbers, so nothing stops an employer calling someone a millwright. What actually controls the work is the equipment manufacturer's tolerances and the plant's own procedures. Get a shaft alignment wrong by a few thousandths of an inch and a bearing that should last years fails in months. Many millwrights also hold welding qualification tests, rigging cards and site safety certificates, and those are the papers a new employer asks to see.
Things you don't need, but that help.
Laser alignment and vibration analysis
Predicting a bearing failure before it happens is worth a great deal to a plant, and the training is short.
Welding qualification tests
A millwright who can weld to code can take jobs others cannot.
Rigging and crane signaling
Moving a 20 ton gearbox into position safely is its own specialty.
Hydraulics and mechatronics
Modern machinery is mechanical, hydraulic and electronic at once. People who cross those lines get the interesting work.
An industrial maintenance certificate
A one year community college program makes you an obvious apprenticeship pick.
Driver's license and a reliable vehicle
Plants sit outside towns and jobs can be in another state.
Confined space and fall protection training
Short courses that every industrial site requires anyway.
Willingness to travel
Shutdown work is often in another state, and the crews who travel for it get more of it.
Day to day, pros and cons, where you'd work.
Report at 6am or 7am for a safety briefing and the day's plan. Lock out the machine so nobody can start it while you are inside it. Pull a coupling, change a bearing or a gearbox, then spend as long as it takes getting the shafts aligned, checking and rechecking with dial indicators or a laser. Rigging, chain falls, grinding, and a lot of crawling into places built for machines rather than people. On a maintenance job it is planned. On a breakdown the plant is losing money every minute you take.
The good
The hard parts
Things people don't tell you.
Millwrights originally built and maintained water mills and grain mills, making the gears and shafts themselves out of wood. The machines changed completely. The name and the core skill, getting rotating parts to line up, did not.
It sounds odd for a trade that works in steel, but millwrights are one of the eight trades represented by the United Brotherhood of Carpenters, alongside floor coverers and pile drivers.
Every list is built from the same numbers shown above, so you can see where this career sits next to the others.

They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise. How every figure on this site is sourced and checked.
