How much do millwrights make in Indiana in 2026?

The median millwright in Indiana earns $77,140 a year, which works out to about $37.09 an hour based on a standard 2,080-hour work year. That number comes from BLS OEWS data collected through May 2025 and covers millwrights across the state — manufacturing plants, food processing facilities, auto assembly lines, steel mills, and anywhere else heavy machinery gets installed, aligned, and maintained.

Pay spreads out significantly depending on where you sit in the experience range. The 25th percentile lands at $60,510 a year, or roughly $29.09 an hour. That's typically where you'll find workers who are newer to the trade, still building their ticket on rigging, precision alignment, and machinery installation. The 75th percentile reaches $91,410 — about $43.95 an hour — and that's where experienced hands end up after years of working on complex equipment, reading OEM specs, and handling laser alignment tools without much supervision.

The gap between the 25th and 75th percentile is $30,900 a year. That's not a small difference. It reflects the reality that millwrighting is a highly skill-dependent trade. A worker who can set and align a large centrifugal pump, troubleshoot a gearbox, and safely rig a 50-ton piece of equipment to a tight tolerance is simply worth more than someone still learning those tasks. Time in the trade matters, but so does the variety of equipment you've worked on.

Indiana's industrial base plays directly into millwright demand. The state has a heavy concentration of manufacturing — steel production in the northwest around Gary and East Chicago, auto-related manufacturing scattered through the central and southern parts of the state, food and beverage processing throughout, and a growing logistics and warehousing sector that requires conveyor and automated sortation system work. Millwrights in the northwest corner of the state, near the Chicago metro labor market, often see competitive wages because they're drawing from a tight pool of skilled workers. Workers in smaller markets in central or southern Indiana may see rates closer to the lower end of the range, though industrial plant work tends to pay better than general maintenance roles regardless of geography.

Overtime is a meaningful factor in annual take-home pay for millwrights. Planned outages, shutdowns, and turnarounds — common in steel, refining, and heavy manufacturing — can push a worker's actual hours well above 2,080 in a given year. A millwright at the median base rate of $37.09 an hour earns $55.64 per overtime hour. A two-week planned shutdown with 60-hour weeks adds up fast and can push a median earner's actual annual income noticeably above the reported figure. The BLS data captures straight-time base wages and does not fully reflect what workers take home when overtime is heavy.

Apprenticeship is the standard path into millwrighting. Programs typically run four to five years and combine on-the-job hours with related technical instruction covering blueprint reading, rigging, hydraulics, precision measurement, and machinery installation. Completing an apprenticeship puts a worker in a much stronger position for the higher end of the pay scale — not just because of the credential, but because of the documented breadth of skills. Workers who have gone through a formal program and can demonstrate competency across multiple equipment types are the ones plants call first for shutdown work and the ones who get the higher-paying specialty assignments.

Some millwrights in Indiana work under a collective bargaining agreement. If your employer operates under a union contract, your pay rate and benefit structure are set by that agreement, not by state averages. The terms vary by agreement, so check your specific contract for accurate information on rates, overtime rules, and benefit contributions. The BLS figures here represent a broad mix of union and non-union workers across the state.

Certifications can add leverage for millwrights looking to move up. Rigging certifications, NCCER credentials, and documented experience with specific OEM equipment — especially in the auto and steel sectors — signal to employers that you bring something beyond basic mechanical skills. Workers who can also handle vibration analysis or use laser alignment equipment tend to command higher rates, particularly in plants where downtime is expensive and precision matters. If you're sitting near the 25th percentile and want to close the gap to the median or beyond, identifying the specific skills that your current or target employer values most is a more direct path than simply accumulating years on the job.
