Mechanical Engineer Salary by Education

How degrees and certifications affect pay. A master's adds $8K to $15K at every level. A PE license adds $5K to $16K. A PhD adds $15K to $25K but delays earnings by 4 to 6 years.

Degree Deep Dives

Bachelor of Science - The Standard Path

Starting: $65,000 - $72,000 | Mid-career: $95,000 - $105,000

A BS in Mechanical Engineering from an ABET-accredited program is the standard entry requirement for the vast majority of ME roles. It is sufficient for career paths up to and including senior engineer, engineering manager, and director at most companies. The coursework (thermodynamics, fluid mechanics, materials science, machine design, controls) provides the foundation for all ME specializations. ABET accreditation matters because it is required for FE/PE licensure eligibility.

Master of Science - Strategic Specialization

Starting: $72,000 - $85,000 | Mid-career: $105,000 - $125,000

An MS adds $8,000 to $15,000 at every experience level and compounds over a career. The premium is highest in R&D roles, aerospace specialization, and big tech hardware where advanced technical depth is valued. It is less impactful in manufacturing, HVAC, and general engineering services where hands-on experience matters more than credentials. Best approach: have your employer pay for it through tuition reimbursement programs (Boeing, Lockheed, Raytheon all offer this). A part-time MS while working full-time gives you the credential without the lost-income penalty.

PhD - Narrow but High-Impact

Starting: $85,000 - $100,000 | Mid-career: $120,000 - $150,000

A PhD adds $15,000 to $25,000 in salary premium but requires 4 to 6 additional years. The lost earnings during those years ($260,000 to $400,000) often offset the premium for decades. The PhD is most valuable for: national laboratory research (Sandia, Los Alamos, Oak Ridge), academic positions, aerospace R&D, and specialized roles in MEMS, computational fluid dynamics, or advanced materials. It is least valuable in industry roles where a BS or MS with equivalent experience is preferred. Many PhD programs are fully funded with stipends of $30,000 to $40,000/year.

Professional Certifications

Certifications that directly impact ME salary, ranked by premium.

Professional Engineer (PE)

+$5,000 - $16,000

Time to obtain: 4 years post-FE + exam

Required for consulting, public infrastructure, and signing off on designs. ASME survey shows PE-licensed MEs earn median $133,000 vs $117,000 unlicensed.

Fundamentals of Engineering (FE)

+$2,000 - $5,000

Time to obtain: Exam during/after school

First step toward PE. Signals professional intent to employers. Best taken during senior year of undergrad while material is fresh.

Certified SolidWorks Expert (CSWE)

+$3,000 - $8,000

Time to obtain: Self-study + exam

Demonstrates advanced CAD proficiency. Valued in product design and manufacturing roles where SolidWorks is standard.

Project Management Professional (PMP)

+$5,000 - $12,000

Time to obtain: 36 months experience + exam

Most valuable for MEs moving into engineering management. Proves project leadership ability across industries.

Six Sigma Green/Black Belt (SSGB/SSBB)

+$4,000 - $10,000

Time to obtain: Training + project + exam

Process improvement certification. Valuable in manufacturing, automotive, and aerospace for quality engineering roles.

When NOT to Get a Graduate Degree

Honest analysis. A graduate degree is not always worth the investment.

Your employer will not pay for it

An out-of-pocket MS costs $40K to $80K plus two years of reduced income (if part-time) or lost income (if full-time). The $8K to $15K annual premium takes 3 to 8 years just to break even. If your employer offers tuition reimbursement, the math changes completely.

You work in manufacturing or HVAC

These sectors value hands-on experience and PE licensure more than graduate credentials. A BS engineer with 5 years of experience and a PE license often earns more than an MS engineer with 3 years.

You would rather gain 2 years of experience

Two years of industry experience provides real-world skills, professional network, and $140K to $180K in earned income. In many career paths, the experience is more valuable than the degree.

You want a management career

If your goal is engineering management or director, an MBA may be more valuable than an MS in ME. Or better yet, demonstrate leadership on the job. Most engineering managers were promoted based on performance, not credentials.
