What it pays
Government survey numbers — not estimates, not ads.
Half of all Electro-Mechanical and Mechatronics Technologists and Technicians in the U.S. earn more than $73,900 a year — the middle 80% land between $47,840 and $109,890. About 15,520 people in the U.S. do this work. Figures are for the U.S. occupation group “Electro-Mechanical and Mechatronics Technologists and Technicians”. (U.S. Bureau of Labor Statistics survey, published 2025.) In India, Professionals earn about ₹38,298 a month on average — around ₹4.6 lakh a year (government PLFS survey via ILOSTAT, occupation-family figure).
