What is the GRE Calculator Policy?
The question of “can I use a calculator on the GRE” has a straightforward but section-specific answer. The Graduate Record Examinations (GRE) provides an on-screen calculator, but only for the Quantitative Reasoning sections. You are not permitted to use a calculator for the Verbal Reasoning or Analytical Writing sections. Furthermore, you are strictly prohibited from bringing your own physical calculator into the test center or using one during the at-home test.
This policy is designed to test a range of skills. The Quantitative section assesses your ability to solve problems, which can sometimes involve tedious arithmetic. The on-screen calculator is a tool to prevent you from getting bogged down in complex calculations. However, many questions are designed to test your logical reasoning and number sense, where using the calculator can actually be slower than using estimation or recognizing number properties. Understanding when and when not to use it is a critical part of your GRE strategy.
Common Misconceptions
- Misconception 1: You can bring your own calculator. This is false. Only the provided on-screen calculator is allowed. Attempting to use your own is a violation of test rules.
- Misconception 2: The calculator is available for all sections. This is also false. It is exclusive to the Quantitative Reasoning sections.
- Misconception 3: You should use the calculator for every Quant question. This is a poor strategy. Many questions are faster to solve with mental math, estimation, or logic. Over-reliance on the calculator can waste precious time.
Understanding the On-Screen GRE Calculator
The on-screen calculator provided by ETS is a basic, non-scientific calculator. It’s crucial to understand its limitations and features before test day. The primary purpose of the calculator is to handle arithmetic that is too cumbersome for mental math. Knowing its functions helps you decide if it’s the right tool for a given problem.
The core functions are simple. It performs addition, subtraction, multiplication, and division. It also includes a square root function and basic memory functions (Memory Store, Memory Recall, Memory Clear). There are no advanced functions like exponents, logarithms, or trigonometric operations. This simplicity reinforces the idea that the GRE is a test of reasoning, not complex computation. The question “can I use a calculator on the GRE” is less about permission and more about strategic application.
Calculator Functions (Variables) Table
| Function/Button | Meaning | Typical Use Case |
|---|---|---|
| 0-9, . (decimal) | Number and Decimal Entry | Inputting numbers for calculation. |
| +, -, *, / | Basic Arithmetic Operations | Adding, subtracting, multiplying, or dividing numbers. |
| √ (sqrt) | Square Root | Finding the square root of a non-negative number. |
| M+ | Memory Add | Adds the current number on the display to the number in memory. |
| MR | Memory Recall | Displays the number currently stored in memory. |
| MC | Memory Clear | Clears the memory, setting it to zero. |
| C / CE | Clear / Clear Entry | Clears the last entry or the entire calculation. |

Practical Examples (Real-World Use Cases)
Knowing the answer to “can I use a calculator on the GRE” is only the first step. The next is knowing *when*. Here are two examples illustrating strategic calculator use.
Example 1: When to Use the Calculator (Numeric Entry)
Question: A company’s profit was $4,517,820 in Year 1. In Year 2, its profit increased by 11.5%. What was the company’s profit in Year 2, rounded to the nearest dollar?
Interpretation: This is a Numeric Entry question that requires a precise calculation with messy numbers. Mental math is impractical and prone to error. This is a perfect scenario for the calculator.
- Step 1: Calculate the increase amount. Type `4517820 * 0.115` into the calculator. The result is `519549.3`.
- Step 2: Add this increase to the original profit. Type `4517820 + 519549.3`. The result is `5037369.3`.
- Step 3: Round to the nearest dollar. The final answer is `5,037,369`.
Conclusion: The calculator saved time and ensured accuracy for a calculation that was not meant to test number sense, but rather the ability to set up a percentage problem.
Example 2: When NOT to Use the Calculator (Quantitative Comparison)
Question:
Quantity A: (49 * 78) / 13
Quantity B: 49 * 6
Interpretation: A test-taker’s first instinct might be to calculate Quantity A precisely: `49 * 78 = 3822`, then `3822 / 13 = 294`. Then calculate Quantity B: `49 * 6 = 294`. This leads to the correct answer (The two quantities are equal), but it’s slow.
A Better Approach (Logic): Look at Quantity A. Instead of multiplying first, notice that 78 is divisible by 13. `78 / 13 = 6`. So, Quantity A simplifies to `49 * 6`. This is identical to Quantity B. The comparison is made instantly without any complex calculation. This highlights how for many GRE questions, especially Quantitative Comparisons, looking for logical shortcuts is far more efficient. Over-relying on the calculator here would be a strategic error.

Key Factors That Affect Your Calculator Strategy
A successful GRE Quant strategy goes beyond simply knowing if you can use a calculator on the GRE. It involves a dynamic decision-making process based on several factors.
- Question Type: As our tool shows, this is the most important factor. Quantitative Comparison questions often reward logic and estimation, while Numeric Entry questions may require precise calculation.
- Time Management: The GRE is a timed test. If you are short on time, punching numbers into a clunky on-screen calculator can be a costly delay. Fast mental math or estimation is often superior.
- Number Properties: Are the numbers large, ugly decimals, or are they friendly integers with clear relationships (e.g., multiples of 5 or 10)? The nature of the numbers themselves should guide your decision.
- Your Estimation Skills: If you are skilled at quickly approximating answers, you can often eliminate answer choices in multiple-choice questions without calculating precisely. This is a skill worth developing. Check out our advanced quant strategies for more.
- Data Interpretation Sets: These questions often involve percentages, averages, and comparisons based on charts and graphs. The numbers can be complex, making the calculator a very valuable tool in this specific context.
- Personal Math Fluency: Be honest about your own strengths. If you are prone to simple arithmetic errors under pressure, using the calculator as a quick double-check can be a smart move, even for easier calculations.
Frequently Asked Questions (FAQ)
No. You are strictly forbidden from bringing your own calculator (physical or otherwise) to the GRE test, whether at a test center or for the at-home version. You must use the on-screen calculator provided.
No. The on-screen calculator is only available during the Quantitative Reasoning sections of the GRE. It will not be present for the Verbal Reasoning or Analytical Writing sections.
No, it is a very basic calculator. It can perform addition, subtraction, multiplication, division, and square roots. It does not have exponents, logarithms, or trigonometric functions. This reinforces that the GRE tests reasoning, not complex computation.
Absolutely. The on-screen calculator can feel clunky to use with a mouse. You should use the official PowerPrep practice tests from ETS to get accustomed to its interface, so it doesn’t slow you down on test day. Familiarity is key to efficient use.
Definitely not. Many GRE questions are designed to be solved more quickly using mental math, estimation, or by recognizing number properties. Over-reliance on the calculator is a common mistake that wastes time. The core question isn’t just “can I use a calculator on the GRE,” but “*should* I?”
During the Quantitative Reasoning sections, there will be a “Calculator” button on the screen. Clicking it will open the calculator in a separate window that you can move around the screen. Our test day checklist can help you prepare for the interface.
These are for multi-step calculations. M+ adds the current display value to memory. MR (Memory Recall) retrieves the value from memory to the display. MC (Memory Clear) resets the memory to zero. They can be useful for problems where you need to store an intermediate result.
No, the policy is identical. In both formats, you are provided the same on-screen calculator for the Quant sections only and are prohibited from using any external calculator. For more on the different formats, see our comparison of GRE test types.
