A mechanical engineer salary is an important consideration for students choosing an engineering degree, recent graduates entering the job market, and experienced professionals planning their next career move. Mechanical engineers work across manufacturing, automotive, aerospace, energy, robotics, research, and other industries. However, their earnings can differ considerably depending on experience, education, location, specialization, and employer.
In the United States, mechanical engineers earned a median annual wage of $104,110 in May 2025, according to the U.S. Bureau of Labor Statistics (BLS). This equals approximately $8,676 per month or $50.05 per hour before taxes when using the published hourly median. Nevertheless, not every engineer receives the same compensation. Entry-level professionals, experienced specialists, and engineering managers may have substantially different earnings.
This guide explains the mechanical engineer salary, its definition and meaning, average earnings, hourly and monthly pay, industry differences, education, experience, and practical salary examples. It also explains how aspiring engineers can evaluate compensation and identify opportunities to improve their earning potential in the United States.
What Is Mechanical Engineer Salary?
Mechanical engineer salary refers to the compensation an engineering professional receives for performing mechanical engineering responsibilities. It is generally expressed as an annual salary, although employers may also calculate compensation by the hour, month, or pay period.
The amount depends on the professional’s responsibilities and the value of their technical contribution. For example, a junior mechanical design engineer may earn less than a senior engineer responsible for complex product development, engineering calculations, project coordination, or technical approval.
A mechanical engineer may receive a basic salary along with additional benefits, depending on the employer. These benefits can include health insurance, retirement contributions, paid leave, performance bonuses, overtime payments, relocation assistance, and other compensation.
Therefore, when comparing two employment offers, candidates should examine the complete compensation package instead of looking only at the advertised annual salary.
For a broader understanding of the profession, readers can explore What Is Mechanical Engineering?, which explains the discipline, its applications, and the principles used by engineering professionals.
Mechanical Engineer Salary: Meaning and Definition
The meaning of mechanical engineer salary is the financial compensation paid to an individual for applying mechanical engineering knowledge, technical skills, and professional experience to an organization’s activities.
In practical terms, this compensation reflects several factors, including the complexity of engineering work, industry requirements, geographical location, education, and professional responsibilities.
For example, an engineer who designs mechanical components using Computer-Aided Design (CAD) software may have a different compensation structure from a manufacturing engineer who manages production processes. Similarly, professionals working in aerospace research, advanced manufacturing, and specialized engineering services may have different earning opportunities.
It is also important to understand three common salary terms:
Mean salary: The arithmetic average of all reported wages. It is calculated by adding the reported salaries and dividing the total by the number of workers.
Median salary: The middle wage in a distribution. Half of the workers earn more than the median, while the other half earn less.
Salary range: The difference between lower and upper compensation levels for a particular occupation, employer, location, or experience group.
These measurements provide different perspectives on earnings. A mean salary can be influenced by exceptionally high wages, whereas a median provides a useful picture of the middle of the workforce.
Average Mechanical Engineer Salary in the United States
According to the U.S. Bureau of Labor Statistics, the median annual wage for mechanical engineers was $104,110 in May 2025. The corresponding published median hourly wage was $50.05.
The BLS also reported a mean annual wage of $113,610. The difference between these two figures demonstrates why average and median salaries should not be treated as interchangeable.
The following table presents the national wage distribution.
| Wage measurement | Annual salary | Hourly wage |
|---|---|---|
| 10th percentile | $73,990 | $35.57 |
| 25th percentile | $84,130 | $40.45 |
| 50th percentile (median) | $104,110 | $50.05 |
| 75th percentile | $132,590 | $63.75 |
| 90th percentile | $164,340 | $79.01 |
| Mean (average) | $113,610 | $54.62 |
Source: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025.
These figures describe the overall occupational wage distribution, not guaranteed starting salaries or fixed pay scales. For example, the 10th percentile does not mean every entry-level engineer earns $73,990. It means that approximately 10% of workers earned at or below that wage level.
Similarly, the 90th percentile represents a high earning level within the occupation. Reaching it may involve extensive experience, specialized expertise, higher responsibility, or employment in a well-paying industry.
You can consult the official BLS Mechanical Engineers Occupational Outlook Handbook for current occupational information, pay, education, and employment projections.
How Much Does a Mechanical Engineer Make Per Year?
A mechanical engineer in the United States can earn different amounts depending on qualifications, experience, industry, and location. The BLS median of $104,110 provides a national benchmark, while individual salaries can fall below or above that figure.
For example, consider three hypothetical professionals:
An engineer earning $80,000 annually receives a salary below the national median. This could be reasonable for someone with limited experience, a position in a lower-paying market, or an employer with a different compensation structure.
An engineer earning $104,110 annually is receiving compensation equal to the May 2025 national median.
A senior engineer earning $140,000 annually receives compensation above the national median. Such a salary may reflect specialized responsibilities, extensive experience, a high-paying industry, or a competitive employment market.
These examples are illustrative rather than official experience-based salary brackets. Actual offers depend on the employer and individual circumstances.
The national median is useful for comparison, but candidates should also examine local wages and the responsibilities attached to a particular position.
Mechanical Engineer Salary Per Month
Mechanical engineer salary per month is a useful measurement for employees who want to understand their regular earnings, prepare a household budget, or compare employment offers.
Using the May 2025 BLS annual median of $104,110, the approximate monthly gross salary is:
$104,110 ÷ 12 = $8,675.83
This means the national median corresponds to approximately $8,676 per month before taxes and deductions.
The following examples show how annual salaries translate into monthly gross compensation.
| Annual salary | Approximate monthly gross |
|---|---|
| $70,000 | $5,833 |
| $80,000 | $6,667 |
| $90,000 | $7,500 |
| $100,000 | $8,333 |
| $104,110 | $8,676 |
| $120,000 | $10,000 |
| $140,000 | $11,667 |
| $160,000 | $13,333 |
These calculations divide annual salary by 12. They do not represent take-home pay.
Actual monthly income depends on federal income taxes, state and local taxes, Social Security, Medicare, retirement contributions, insurance premiums, and other deductions.
For instance, an engineer earning $104,110 annually will not necessarily receive $8,676 in their bank account every month. That amount is the gross monthly equivalent, not the net salary.
Mechanical Engineer Salary Per Hour
Hourly compensation is another important way to evaluate a mechanical engineering job, particularly for contract workers, consultants, and professionals whose employment arrangements involve hourly pay.
The BLS reported a median hourly wage of $50.05 for mechanical engineers in May 2025. Its mean hourly wage was $54.62.
For comparison, the approximate hourly equivalents of selected annual salaries can be calculated using 2,080 working hours per year, representing 40 hours per week over 52 weeks.
| Annual salary | Approximate hourly equivalent |
|---|---|
| $70,000 | $33.65 |
| $80,000 | $38.46 |
| $90,000 | $43.27 |
| $100,000 | $48.08 |
| $104,110 | $50.05 |
| $120,000 | $57.69 |
| $140,000 | $67.31 |
| $160,000 | $76.92 |
These are mathematical equivalents, not additional BLS wage observations. Paid leave, unpaid time, overtime, bonuses, and different working schedules can change the actual value of an employment arrangement.
For example, an employee earning $100,000 with paid holidays, health insurance, and retirement contributions may receive a different overall package from a contractor billing an equivalent hourly rate without those benefits.
Mechanical Engineer Salary by Industry
The industry in which an engineer works can have a significant influence on compensation. Different industries require different technical capabilities, levels of responsibility, and engineering expertise.
According to the BLS, the following were the median annual wages for mechanical engineers in selected industries in May 2025.
| Industry | Median annual wage |
|---|---|
| Scientific research and development services | $132,040 |
| Computer and electronic product manufacturing | $106,870 |
| Transportation equipment manufacturing | $105,560 |
| Architectural, engineering, and related services | $103,440 |
| Machinery manufacturing | $98,620 |
Scientific research and development services recorded the highest median among these listed industries. However, this does not mean every research engineer earns more than every manufacturing engineer.
Scientific Research and Development
Research and development organizations employ mechanical engineers to investigate technical problems, develop prototypes, evaluate new materials, and improve existing products. Their work may involve experimental testing, simulation, advanced mechanical systems, and innovative technologies.
Specialized research responsibilities can require advanced technical knowledge and, in some positions, postgraduate qualifications.

Mechanical engineers contribute to the development and manufacturing of electronic equipment, computer hardware, thermal management systems, mechanical enclosures, and precision components.
Their responsibilities may include product design, heat-transfer analysis, testing, material selection, and manufacturing support.
Transportation Equipment Manufacturing
This industry includes engineering work related to automobiles, aircraft-related equipment, rail transportation, and other transportation products.
Engineers may contribute to vehicle components, mechanical assemblies, manufacturing processes, testing, and equipment performance.
Architectural and Engineering Services
Engineering consulting firms employ professionals to develop designs, prepare technical documentation, evaluate equipment, and support construction or industrial projects.
Mechanical engineers may specialize in building services, HVAC, energy systems, mechanical installations, and engineering design.
Machinery Manufacturing
Machinery manufacturers require engineers to develop industrial equipment, production machinery, mechanical assemblies, and automated systems.
Professionals may work in design, production engineering, quality assurance, equipment testing, and product improvement.
Industry selection can influence earning opportunities, but location, experience, employer size, and individual performance remain important considerations.
Mechanical Engineer Salary by Experience
Experience is an important factor in salary development. As professionals gain practical knowledge, they may become responsible for more complex designs, technical decisions, project coordination, and engineering supervision.
However, the BLS national wage distribution does not directly represent salary levels for specific experience bands. Therefore, it would be misleading to present the official 10th, 25th, 50th, 75th, and 90th percentiles as exact entry-level, mid-career, or senior salaries.
Instead, candidates should use the national wage distribution as a benchmark and compare it with actual vacancies requiring similar experience.
Entry-Level Mechanical Engineers
Recent graduates generally apply for graduate engineer, junior design engineer, production engineer, manufacturing engineer, or other early-career positions.
Their compensation depends on the employer’s training program, location, degree, internship experience, and technical skills.
Employers may value practical experience with CAD software, engineering drawings, manufacturing processes, laboratory testing, and technical documentation.
Mid-Level Mechanical Engineers
Professionals with several years of relevant experience may take responsibility for design modifications, equipment performance, project tasks, production improvements, or technical investigations.
They may also support junior engineers and coordinate with manufacturing, procurement, quality, and maintenance teams.
As responsibilities increase, opportunities for higher compensation may become available.
Senior Mechanical Engineers
Senior professionals often handle more complex engineering assignments. Their responsibilities may include technical reviews, design verification, project coordination, engineering risk assessment, mentoring, and specialist problem-solving.
Some move into technical leadership or engineering management, while others remain focused on advanced technical work.
A senior title alone does not guarantee a particular salary. Employers evaluate the complexity of the work, demonstrated results, and business requirements.
Mechanical Engineer Salary by Location and State
Geographical location can significantly influence mechanical engineering compensation in the United States.
States and metropolitan areas differ in industrial activity, employer concentration, cost of living, workforce competition, and demand for specialized engineering skills.
For example, a region with a strong aerospace or advanced manufacturing sector may provide opportunities for professionals with specialized mechanical design and testing experience. Other locations may offer opportunities in machinery manufacturing, transportation equipment, engineering consulting, or energy-related services.
However, a higher nominal salary does not automatically provide a better standard of living. Housing costs, transportation, taxes, healthcare expenses, and other living costs should also be considered.
The BLS Occupational Employment and Wage Statistics program publishes wage estimates for national, state, metropolitan, and nonmetropolitan areas.
Readers can use the official BLS State and Area Wage Data to investigate mechanical engineer earnings in a particular location.
For a practical comparison, candidates should examine:
- Local median wages for mechanical engineers.
- The number and types of employers in the area.
- Housing and transportation costs.
- State and local tax obligations.
- Availability of specialized engineering positions.
- Employer benefits and opportunities for professional development.
Comparing these factors provides a more useful picture than choosing a location solely because it advertises a higher salary.
Mechanical Engineer Starting Salary
A starting salary is the compensation offered to a professional entering the occupation or beginning a new position with limited relevant experience.
For mechanical engineering graduates, starting compensation can vary according to the employer, location, academic preparation, internship experience, and technical capabilities.
A graduate applying to a manufacturing company may receive a different offer from someone entering an aerospace research organization or engineering consultancy.
Some employers recruit graduates through structured training programs. Others hire directly into design, production, maintenance, quality, testing, or engineering support positions.
Candidates should examine the job description carefully and compare the responsibilities with their qualifications.
It is also useful to distinguish between a starting salary and the national median. The BLS median includes workers across the occupation, including experienced professionals. It should not be interpreted as the expected first-year salary for every graduate.
Does a Master’s Degree Increase Mechanical Engineer Salary?
A master’s degree can improve access to certain specialized engineering opportunities, but it does not guarantee a higher salary.
Postgraduate education may be valuable in areas such as advanced mechanical design, thermal sciences, fluid mechanics, computational analysis, robotics, materials engineering, and research and development.
For example, an engineer with postgraduate knowledge of Computational Fluid Dynamics (CFD) may pursue positions involving fluid-flow analysis, aerodynamic performance, thermal systems, or advanced equipment development.
Similarly, a professional specializing in Finite Element Analysis (FEA) may work on structural simulation, component strength, vibration analysis, and design verification.
Nevertheless, employers also evaluate practical experience, communication, technical judgment, project results, and the ability to solve real engineering problems.
Candidates should therefore consider the cost of postgraduate education, potential career benefits, and the specific qualifications required for their preferred positions.
Mechanical Engineering Specializations and Their Earning Opportunities
Mechanical engineering is a broad discipline with multiple technical specializations. Each area has different responsibilities and may provide different compensation opportunities.
Mechanical Design Engineering

Mechanical Engineer Salary Examples
Practical examples can make salary figures easier to understand. The following scenarios are hypothetical and illustrate how different compensation levels affect gross earnings.
Example 1: A Graduate Engineer Earning $80,000
Suppose a newly employed mechanical engineer receives an annual salary of $80,000.
The approximate monthly gross salary is $6,667, while the hourly equivalent is $38.46 using a 2,080-hour working year.
This salary is below the May 2025 national median, but it may be appropriate for a particular entry-level position or geographical market.
Example 2: An Engineer Earning the National Median
Consider a professional receiving $104,110 annually.
This corresponds to approximately $8,676 per month and $50.05 per hour using the published BLS median hourly figure.
This example represents the national median benchmark, not a guaranteed salary for a particular job title or experience level.
Example 3: An Experienced Engineer Earning $140,000
A mechanical engineer earning $140,000 annually receives approximately $11,667 per month before taxes and deductions.
The hourly equivalent is approximately $67.31 using 2,080 annual working hours.
This hypothetical salary is above the national median and may be associated with specialized responsibilities, experience, location, or employer compensation policies.
These examples demonstrate why candidates should evaluate salary figures in context rather than assuming that one national benchmark applies to every professional.
Mechanical Engineer Salary and Career Outlook
Mechanical engineering offers career opportunities across established and emerging industries. The development of automation, advanced manufacturing, transportation technologies, energy systems, and robotics continues to create engineering challenges requiring mechanical expertise.
According to the BLS, employment of mechanical engineers is projected to grow by 11% between 2025 and 2035. The agency also projects approximately 17,800 openings per year on average over this period.
These figures relate to employment opportunities in the United States, not worldwide demand.
Engineers may contribute to the development of more efficient machines, electric vehicles, industrial automation, renewable energy equipment, and advanced manufacturing processes.
However, employment growth does not guarantee higher salaries for every worker. Compensation continues to depend on employer requirements, local labor-market conditions, technical skills, and professional performance.
For students planning an engineering career, building a strong foundation in mathematics, physics, design, materials, mechanics, and practical problem-solving remains important.
