GRE Calculator Decision Tool
GRE Calculator Policy at a Glance
| GRE Section | Calculator Provided? | Type of Calculator |
|---|---|---|
| Quantitative Reasoning | Yes | Basic on-screen 4-function calculator with square root and memory. |
| Verbal Reasoning | No | N/A |
| Analytical Writing | No | N/A |
What is the Policy on ‘Do you use a calculator on the GRE’?
The question of whether you can use a calculator on the GRE is a common one, and the answer is both yes and no. You are not allowed to bring your own calculator to the test. However, an on-screen calculator is provided for specific parts of the exam. The GRE is designed to test your reasoning abilities, not your ability to perform complex manual calculations.
The on-screen calculator is available only during the Quantitative Reasoning sections of the GRE. For the Verbal Reasoning and Analytical Writing sections, you will not have access to any calculator. This policy ensures a level playing field for all test-takers and focuses the exam on analytical and logical skills.
Understanding when and how to properly use this tool is a critical part of a successful GRE strategy. Over-reliance can waste time, while strategic use can help with tedious arithmetic. Many test-takers find it beneficial to practice with mock tests, such as the GRE POWERPREP tests, to get used to the on-screen tool.
The GRE Calculator ‘Formula’ and Explanation
Unlike a financial or scientific calculator, the rule for the GRE calculator isn’t a mathematical formula but a simple decision rule. It’s based entirely on the section of the test you are in.
The “formula” can be expressed as: IF Section = "Quantitative Reasoning" THEN Calculator = Available ELSE Calculator = Not Available
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Section | The specific section of the GRE General Test. | Categorical | {Quantitative Reasoning, Verbal Reasoning, Analytical Writing} |
| Calculator Availability | The binary state of whether the on-screen tool is provided. | Boolean (Yes/No) | {Available, Not Available} |
The calculator provided is a basic four-function model with addition, subtraction, multiplication, division, and a square root function. It respects the order of operations (PEMDAS).

Practical Examples
Example 1: Strategic Calculator Use (Time Saver)
Question: A store buys a batch of 500 widgets for $1.97 each and sells them for $4.15 each. What is the total profit for the entire batch, assuming all are sold?
- Inputs: Cost per widget, Sale price per widget, Number of widgets.
- Units: Currency ($), Quantity (unitless).
- Calculation:
- Profit per widget: $4.15 – $1.97 = $2.18
- Total Profit: $2.18 * 500 = $1090
- Result: Using the calculator for 2.18 * 500 is fast and prevents manual error. This is a perfect scenario for using the tool. Trying a GRE practice test will help you identify these scenarios.
Example 2: Inefficient Calculator Use (Time Waster)
Question: Which of the following is greatest?
(A) 49% of 800 (B) 151% of 250 (C) 99% of 400 (D) 24% of 1600 (E) 5% of 8000
- Inputs: Percentages and base numbers.
- Units: N/A.
- Calculation: Instead of calculating each one precisely:
- (A) ~50% of 800 = 400
- (B) ~150% of 250 = 250 + 125 = 375
- (C) ~100% of 400 = 400 (but slightly less)
- (D) ~25% of 1600 = 400
- (E) 5% of 8000 = 10% of 4000 = 400
- Result: Mental estimation and number sense are much faster. Here, 24% of 1600 is (25% – 1%) * 1600 = 400 – 16 = 384. 49% of 800 is (50% – 1%) * 800 = 400 – 8 = 392. 99% of 400 is 400 – 4 = 396. 5% of 8000 is 400. 151% of 250 is 377.5. The answer is (E) but estimation quickly narrows the field. Using the calculator for all five options would be a significant waste of time. Explore our GRE math practice for more examples.

Key Factors That Affect GRE Calculator Strategy
- Problem Type: Questions involving tedious arithmetic, multi-digit multiplication, or long division are good candidates for the calculator.
- Time Management: The on-screen interface can be clumsy. Mental math is often faster for simple calculations. Don’t use it just because it’s there.
- Estimation vs. Precision: For Quantitative Comparison questions or problems that ask for an approximate value, estimation is superior to calculation.
- Number Properties: Many questions test your understanding of concepts like divisibility, primes, or patterns, which a calculator cannot help with.
- The “Transfer Display” Button: For Numeric Entry questions, this button transfers your calculated result directly to the answer box, reducing transcription errors.
- Mental Math Proficiency: The stronger your mental math skills, the less you’ll need the calculator, saving precious seconds on many questions.
Frequently Asked Questions (FAQ)
1. Can I bring my own calculator to the GRE?
No, you are strictly prohibited from bringing your own calculator, including watch calculators or phone apps. You must use the provided on-screen tool.
2. Is the GRE calculator scientific?
No, it is a basic 4-function calculator. It can perform addition, subtraction, multiplication, division, and square roots. It does not have advanced functions like exponents, trigonometry, or logarithms.
3. How do I practice with the official GRE calculator?
The best way is to use the official POWERPREP Online practice tests from ETS, which include a simulation of the actual on-screen calculator. Many third-party free GRE practice tests also offer a similar tool.
4. Does the calculator follow the order of operations (PEMDAS)?
Yes, the on-screen calculator for the computer-based GRE correctly follows the standard order of operations (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
5. Is the calculator the same for the GRE at Home test?
Yes, the on-screen calculator and its functionality are identical for both the at-home version of the GRE and the one administered at a test center.
6. Should I use the calculator for every Quant question?
Absolutely not. This is a common mistake that wastes time. Many questions are designed to be solved more quickly with logic, estimation, or mental math. Use the calculator as a tool, not a crutch.
7. What does the “M+”, “MR”, and “MC” buttons do?
These are memory functions. M+ adds the current number to the memory, MR (Memory Recall) displays the number stored in memory, and MC (Memory Clear) clears the memory.
8. Are there questions that require a calculator?
No question *requires* a calculator, but for some problems with messy numbers, it is a significant advantage and highly recommended to save time and ensure accuracy.
