How much does a Mechanical Engineer make in Maryland?

BLS reports a median annual wage of $111,740 for Mechanical Engineers in Maryland as of the latest OES release. That is the 50th-percentile figure — half earn more, half earn less. The 25th-percentile is $90,740 and the 75th-percentile is $144,390.

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

The 90th percentile lands at $169,270. 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 $144,390.

Where does Maryland rank for Mechanical Engineer pay?

On nominal BLS wages alone, Maryland ranks among the 51 states and DC by median pay. After the BEA cost-of-living adjustment the ordering changes — high-cost states fall, low-cost states rise. Both rankings are shown in the data table on this page.

How wide is the wage spread in Maryland?

P10 to P90 spans $77,980 to $169,270. That spread captures entry-level to top-quartile pay, including specialty differentials and metro-area variance within the state.

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

No — Maryland'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 Maryland?

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 Maryland.
