What does the top of the Mechanical Engineer pay scale look like in Maine?

The 90th percentile lands at $131,870. That tier typically reflects senior roles, specialty certifications, high-cost-of-living metros within the state, or union-negotiated rate cards. Below that, the P75 quartile is $123,960.

How wide is the wage spread in Maine?

P10 to P90 spans $70,180 to $131,870. That spread captures entry-level to top-quartile pay, including specialty differentials and metro-area variance within the state.

Is Maine a 'real-wage arbitrage' state for Mechanical Engineers?

No — Maine's RPP is close to the national 100 baseline, so nominal and real wages move roughly together. Neither an arbitrage nor a penalty state.

What are the limits of these Mechanical Engineer salary numbers?

BLS OES is an employer survey of W-2 wages — it excludes contractor pay, bonuses outside the base wage definition, equity compensation, and tip income. Self-employed practitioners and gig workers are not represented. For occupations with significant non-W-2 income, the BLS figure is a floor, not a complete picture.

Should I negotiate based on the BLS median for Maine?

The BLS median is a calibration anchor, not a ceiling. Use it to validate that an offer is in-band — anything well below the P25 in this state is a flag, anything above the P75 typically requires demonstrable specialty depth, niche credentials, or a high-COL metro within Maine.

When does this data update?

BLS OES releases a new May reference set roughly each spring; we re-run the ETL pipeline within two weeks of release. BEA RPP refreshes annually. The last-synced timestamp at the top of this page reflects the most recent build.

Defense / aerospace vs auto vs HVAC mechanical engineer pay in Maine?

BLS does not segment by industry. In {state}, defense and aerospace primes typically lead on base pay with strong total comp once retention/clearance bonuses layer in (often P75-P90 of the BLS band). Automotive and consumer products sit mid-band. HVAC / building-systems mechanical engineering pays below the BLS median for the first 5 years, then catches up via PE-track roles and design-build firm equity.
