| Manufacturer | Approved Series | Top Pick for FE | Key Advanced Feature |
|---|---|---|---|
| Casio | fx-115 and fx-991 models | fx-991EX ClassWiz | 4×4 Matrix Solver |
| Hewlett Packard | HP 33s and HP 35s | HP 35s | RPN Logic Efficiency |

What are Calculators Allowed on FE?
The calculators allowed on fe are a strictly defined set of devices permitted by the National Council of Examiners for Engineering and Surveying (NCEES) during the Fundamentals of Engineering exam. This policy is in place to ensure a level playing field and to prevent the use of devices with communicative capabilities, text storage, or graphing functions that could compromise exam integrity.
For engineers, choosing from the list of calculators allowed on fe is more than just following a rule; it is a strategic decision. Using a high-performance model like the TI-36X Pro or the Casio fx-991EX can significantly reduce the time spent on repetitive calculations, such as solving systems of linear equations or finding the definite integral of a function. Conversely, using a basic TI-30X model might leave you struggling with manual steps for complex statistics or matrix math.
A common misconception is that any scientific calculator is permitted. This is false. If you bring a non-approved device, such as a TI-84 or a Casio Prizm, it will be confiscated, and you may be barred from the testing center. Only devices explicitly listed on the annual NCEES calculator policy are calculators allowed on fe.
Calculators Allowed on FE Formula and Mathematical Explanation
To quantify the benefit of using specific calculators allowed on fe, we can use an efficiency derivation. The total time spent on the exam is a function of manual calculation speed and the efficiency multiplier provided by the hardware.
The time savings formula used in this tool is:
S = N × Tm × Pa × (1 - Ef)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| N | Total Number of Questions | Count | 110 |
| Tm | Manual Time per Problem | Seconds | 120 – 180 |
| Pa | Advanced Question Percentage | Decimal % | 0.20 – 0.45 |
| Ef | Calculator Efficiency Factor | Ratio | 0.50 – 1.00 |
Practical Examples (Real-World Use Cases)
Example 1: The Civil Engineering Student
A student taking the Civil FE exam uses a TI-30X (Standard). They spend approximately 160 seconds per problem. Out of 110 questions, about 30% involve matrices or complex stats. By switching to a TI-36X Pro (one of the top calculators allowed on fe), they reduce calculation time for those specific questions by 40%. This results in a net saving of approximately 21 minutes, which can be spent reviewing conceptual questions.
Example 2: The Electrical Engineering Student
Electrical exams involve heavy complex number manipulation and vector math. A student using the Casio fx-991EX (Advanced) vs a basic HP model might save up to 25% of their total calculation time simply because the Casio handles polar-to-rectangular conversions natively without multiple menu layers. For this student, choosing the right calculators allowed on fe is the difference between finishing the exam and leaving five questions blank.
How to Use This Calculators Allowed on FE Calculator
1. Select Discipline: Choose your engineering branch to weight the importance of calculation types.
2. Choose Model: Pick your intended device from the list of calculators allowed on fe to apply its specific efficiency factor.
3. Input Base Speed: Enter how many seconds it takes you to solve a problem with basic tools. Use 150 seconds as a standard baseline.
4. Analyze Results: Review the time saved and the average time available per question to plan your exam pacing.
Key Factors That Affect Calculators Allowed on FE Results
1. Internal Memory: While no calculators allowed on fe permit persistent text storage, the number of variables (X, Y, Z, A, B, C) you can store during a single problem session impacts speed.
2. Solar vs. Battery Power: Most approved models are dual-power. Relying on a battery-only model without a fresh cell is a risk NCEES warns against.
3. Equation Solvers: The ability to solve 2×2 and 3×3 systems of equations instantly is the primary time-saver in the calculators allowed on fe list.
4. Display Quality: “Multiview” or “ClassWiz” displays show fractions and radicals exactly as they appear in the FE Handbook, reducing transcription errors.
5. RPN vs. Algebraic Logic: HP calculators often use Reverse Polish Notation. If you aren’t trained in RPN, these calculators allowed on fe will actually slow you down.
6. Unit Conversions: Some models have built-in constants (e.g., gravity, gas constant) which save precious seconds looking at the reference handbook.
