Sterile Processing Technician Salary in Michigan 2026,
$45,670 Median | BLS Data by City

A median $45,670 a year, or $21.96 an hour, per BLS OEWS May 2025 — 4.3% below the national median of $47,700. The band is tight: $37,750 at the 10th percentile, $39,760 at the 25th, $49,690 at the 75th and $58,050 at the 90th. The whole occupation fits inside about twenty thousand dollars.

No. Michigan issues no licence or registration for sterile processing at any level. What employers require is certification from the Healthcare Sterile Processing Association or the Certification Board for Sterile Processing and Distribution, and that requirement has hardened in recent years because hospital accreditation surveyors examine departmental competency and certification records. In a state that regulates nothing, certification plus documented competency on specific instrument sets is the whole of a technician's formal standing.

Ann Arbor at $50,030, then Lansing-East Lansing $46,830, Flint $46,640, Grand Rapids-Wyoming-Kentwood $45,870 and Detroit-Warren-Dearborn $45,570. Ann Arbor's three-thousand-dollar lead reflects academic and tertiary surgical volume — robotic, transplant and complex specialty instrument sets require more skill and more documented competency than routine trays.

Yes, and faster than most hospital support work. National projections put growth at 10% through 2034 against about 10,900 average annual openings, and Michigan already employs the occupation above the national rate at a location quotient of 1.10 on about 2,420 technicians. The driver is instrument complexity as much as surgical volume: robotic, endoscopic and specialty sets require more processing steps, more tracking and more documented competency than conventional instruments, which raises the skill floor of the job.

Within a band this tight the levers are specific. Certification first, since it is the only formal credential in a state that licenses nothing. Specialty-set competency second — robotic, endoscopic and orthopaedic instrumentation is what carries a technician toward the $49,690 seventy-fifth percentile. Shift differentials third, since departments run around surgical schedules and Michigan's flat tax does not penalise extra hours. And lead technician, educator or supervisory roles fourth, which is what the $58,050 ninetieth percentile describes.

Because the instruments have changed. A generation ago sterile processing largely meant cleaning, assembling and autoclaving conventional trays. Today it includes robotic instrument systems with multi-step disassembly protocols, flexible endoscopes with their own reprocessing standards, loaner orthopaedic sets arriving from vendors with incomplete documentation, and tracking systems that record every step for accreditation purposes. Each of those raises the number of processing steps per surgical case and the competency required to perform them. A 10% growth projection reflects a job that is expanding in content, not only in volume — which is also why Ann Arbor's tertiary surgical volume shows up as a pay premium.

SOC 31-9093 is titled Medical Equipment Preparers and covers sterile processing alongside other equipment preparation roles, so it is a close rather than exact match to the job title. The band from $37,750 to $58,050 is narrow enough that it hides shift differentials, which are a meaningful part of real earnings in a department running evenings and nights. And with the 10th and 25th percentiles only two thousand dollars apart, the estimate says very little about how experience is rewarded — because in this occupation it largely is not.

Certification first, as the only formal credential available. Instrument specialisation second — robotic, endoscopic and complex orthopaedic sets are the scarce competency, and the Ann Arbor figure of $50,030 shows what tertiary surgical volume pays. Shift pattern third, since departments run to surgical schedules and Michigan's flat 4.25% state rate does not rise with extra hours. And lead, educator or supervisory responsibility fourth, which reaches the $58,050 ninetieth percentile and is the practical ceiling without leaving the occupation.
