- NCEES charges US$400 per attempt for the PE Mechanical: Machine Design and Materials exam; separate state board fees may apply.
- The official NCEES e-book practice exam costs $59.95 and contains 80 questions with solutions.
- First-time takers passed at 61% (401 examinees) versus 39% for repeaters (140), so a failed attempt is costly.
- Testing runs through Pearson VUE: 8 hours of exam time inside a 9-hour appointment, in person only.
The Cost at a Glance
When people search for the price of "PE-M:MD&M certification," they often expect a single number. The reality is more layered. The PE Mechanical: Machine Design and Materials exam is a licensure examination administered by the National Council of Examiners for Engineering and Surveying (NCEES), not a standalone credential you buy and renew. That distinction shapes every line item on your budget. If you want a refresher on what the exam actually is, start with What Is PE-M:MD&M? and then come back to the numbers below.
Three categories make up the total cost of getting through the exam:
- Fixed, published fees: the NCEES exam fee of US$400 per attempt.
- Variable fees you do not control: state or territorial licensing board application fees, which differ by jurisdiction.
- Discretionary spending: practice exams, courses, reference books, calculators, travel, and time away from work.
| Cost Item | Amount | Who Sets It |
|---|---|---|
| NCEES PE Mechanical: Machine Design and Materials exam fee | US$400 per attempt | NCEES |
| Official NCEES e-book practice exam | $59.95 | NCEES |
| Board application fees | Varies by board | Your state or territorial board |
| Third-party prep courses and books | Varies widely | Individual providers |
| Travel to a Pearson VUE test center | Depends on distance | You |
| License renewal and continuing competency | Varies by board | Your licensing board |
The $400 NCEES Exam Fee and What It Buys
The NCEES fee is US$400 per attempt. That payment covers one sitting of the computer-based exam delivered at an approved Pearson VUE test center. The exam is offered year-round through computer-based testing, with exams assembled using linear-on-the-fly testing (LOFT), so you are not locked into a single annual window. For scheduling details, see PE-M:MD&M Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
What the appointment looks like
Your fee buys a long, structured day. The appointment is 9 hours, which includes a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break. Actual testing time is 8 hours for 80 questions. Some of those questions are unidentified, unscored pretest items, so you cannot tell which ones do not count.
Question types go beyond simple multiple choice. Expect multiple-correct, point-and-click, drag-and-drop, and numerical fill-in items. Scored items receive correct/incorrect credit with no partial credit, and there is no deduction for wrong answers. The exam is closed book, but you receive a searchable electronic reference handbook, and you may bring one NCEES-approved calculator. Personal reference materials are prohibited.
Board Application and Licensing Fees
NCEES administers the exam, but your licensing board decides whether you are eligible to sit for it and what it charges you to apply. Those board application fees are separate from the US$400 exam fee and vary by jurisdiction, so check your board's current fee schedule before building a budget. Eligibility and any required approval are controlled by the board you select.
A common licensure pathway runs through an EAC/ABET-accredited engineering bachelor's degree, the FE exam, four years of acceptable engineering experience, and then the PE exam. That pathway is common but not universal, so do not assume it applies to you. Our guide to PE-M:MD&M Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through how to confirm your own route.
NCEES Record and reference costs
Some boards accept or require an NCEES Record, which uses five U.S.-licensed engineer references for engineering applications. This is not a universal requirement for sitting the exam, and your board's application rules control. If your board uses it, factor in any associated NCEES service fees and the time needed to line up references.
After you pass: renewal is a board matter
This is a licensure exam, not a separately renewable NCEES certification. After licensure, renewal periods and continuing-professional-competency requirements are set by your issuing state or territorial board. Plan for recurring license renewal costs and continuing education over a career, but get the specifics from your board rather than from a generic estimate.
Preparation Spending: Where the Money Goes
Preparation is the most variable part of your budget, and the place where smart, exam-specific choices save the most. The exam's structure tells you where to concentrate. NCEES publishes question-count ranges per domain rather than fixed percentages, and the distribution is uneven.
| Domain | Official Question Range |
|---|---|
| 1. Basic Engineering Practice | 11-17 |
| 2. Mechanics of Materials | 17-26 |
| 3. Mechanical Attachments | 9-14 |
| 4. Power Transmission | 9-14 |
| 5. Mechanical Components and Assemblies | 16-24 |
| 6. Supportive Knowledge (Machine Design and Materials) | 8-12 |
Mechanics of Materials (17-26 questions)
The largest domain by question range. Paying for depth here, whether through a course module or targeted problem sets, tends to have the best return.
- Stress and strain analysis, including combined loading
- Failure theories and factors of safety
- Fatigue and fracture considerations in machine members
- Deflection of beams and shafts
Mechanical Components and Assemblies (16-24 questions)
The second-largest range, and typically where candidates who work in a narrow specialty find gaps.
- Bearings, springs, gears, and other machine elements
- Sealing, lubrication, and assembly considerations
- Selecting and sizing components against load and life requirements
Together, these two domains account for a large share of the 80 questions. For a deeper breakdown of every content area, see PE-M:MD&M Exam Domains 2026: Complete Guide to All 6 Content Areas.
The official practice exam
The NCEES e-book practice exam costs $59.95. It includes 80 questions and solutions, with 24 new questions including alternative item types, and it is aligned to the October 2025 specifications. At that price it is the cheapest way to see the actual style and difficulty NCEES writes to. One practical note: NCEES has posted errata for the 2025 practice exam (ISBN 978-1-947801-40-0, posted April 1, 2026), so check the errata sheet before concluding that a "wrong" answer reflects your own mistake.
Third-party courses, books, and question banks
Commercial prep options range from inexpensive question banks to full instructor-led courses. Prices vary widely and change often, so compare current listings directly rather than relying on a number in an article. When evaluating any provider, confirm it covers the six-domain structure and the alternative item types, not only classic multiple choice. Our PE-M:MD&M Study Guide 2026: How to Pass on Your First Attempt covers how to choose and sequence resources, and PE-M:MD&M Training outlines the training formats available.
Retake Math: Why a Second Attempt Costs More Than $400
The sticker price per attempt is $400, but the real cost of failing is larger. Every retake means paying the NCEES fee again, plus potentially another board fee depending on your jurisdiction, plus months of additional study time and another long day at a test center.
The pass-rate data underlines why this matters. According to the NCEES table updated July 2026, covering the January-June 2026 testing population, first-time examinees passed at 61% (401 examinees), while repeat examinees passed at 39% (140 examinees). Repeaters are not weaker engineers by definition; the gap partly reflects the mix of who retests. Still, it is a clear signal that a second attempt is not a guaranteed fix, and that preparing properly the first time is the cheapest strategy.

Key Takeaway
Treat the $400 as the minimum, not the total. Spending a modest amount on exam-aligned practice before you register is far cheaper than funding a retake, which repeats the exam fee, any board fees, and weeks of lost study time.
Scoring and what "pass" means for your budget
NCEES reports pass/fail and does not publish a numerical passing score; you need a scaled score that meets the minimum-competence standard. Because there is no point deduction for wrong answers, answering every question is rational. You cannot buy your way to a known target number, which is another reason to invest in broad, domain-balanced practice rather than chasing a score. Details are in PE-M:MD&M Passing Score 2026: Exactly What You Need to Pass.
Hidden and Indirect Costs
Several costs never appear on the NCEES fee page but belong in an honest budget.
- Travel and lodging: Testing is in person at approved Pearson VUE centers. If the nearest center is far away, a 9-hour appointment may mean a hotel the night before.
- Time off work: A full-day appointment plus study leave can mean unpaid days or used vacation.
- Calculator: Only one NCEES-approved calculator is allowed. Confirm your model is on the current approved list before test day, and budget for a replacement if it is not.
- Reference preparation: You will use the searchable electronic reference handbook, which is login-gated. Practice searching it under time pressure rather than buying extra printed references you cannot bring.
- Experience documentation: If your board requires references or detailed experience records, expect administrative time, and possibly NCEES Record fees.
Building a Domain-Aware Budget and Schedule
Because the question ranges are uneven, a good budget front-loads spending where the exam is heaviest. This short example timeline shows how you might sequence both your study time and your purchases around the six domains. Adjust it to your own background; a design engineer who works with gearboxes daily will need less time on Power Transmission than a materials specialist.
Mechanics of Materials
- Largest domain (17-26 questions), so start here
- Work stress, deflection, and failure-theory problems with the handbook open
- Take a diagnostic from the $59.95 official practice exam only after you have seen the format
Mechanical Components and Assemblies, then Power Transmission
- Second-largest domain (16-24 questions)
- Cover bearings, springs, gears, shafts, and drive systems
- Practice numerical fill-in items, which reward unit discipline in SI and USCS
Mechanical Attachments, Basic Engineering Practice, Supportive Knowledge
- Fasteners, welds, and joints in Mechanical Attachments
- Codes, standards, and design practice in Basic Engineering Practice
- Materials selection and supporting topics in Supportive Knowledge
Full-length timed practice
- Simulate the 8-hour testing day, including the shared clock across the two sections
- Remember that submitted sections cannot be reopened
- Review errata and weak domains only
Practice that mirrors this structure is worth more than raw volume. You can drill by domain and take timed sets on the PE-M:MD&M practice test site, which keeps spending low while still exposing you to the item types you will see on exam day. If you want a compact review of the facts above, the PE-M:MD&M Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful companion.
Does the Cost Make Sense? Salary Context
For most engineers, the direct exam cost is small relative to a career. Still, be careful about claiming a precise payoff. The U.S. Bureau of Labor Statistics reports a median annual wage of $104,110 for mechanical engineers as of May 2025. That figure covers the entire occupation; it is not specific to this exam track, and it is not a measured premium for holding a PE license. Whether licensure raises your own pay depends on your employer, your industry, and whether your role requires signing or sealing work.
Licensure tends to matter most where engineers take legal responsibility for designs or work in consulting, public-sector, or regulated settings. Machine design and materials expertise is relevant across equipment manufacturing, industrial machinery, power generation, aerospace and defense suppliers, and consulting firms that evaluate failures and component designs.
