Can I Use My Own Calculator on the GRE?
GRE Calculator Policy Checker
What is the GRE Calculator Policy?
The Graduate Record Examinations (GRE) General Test includes a quantitative reasoning section. A common question among test-takers is: “Can I use my own calculator on the GRE?” The short answer is typically no, unless it’s a very basic, non-programmable, non-connected device. ETS, the administrator of the GRE, provides a built-in calculator for use during the computer-delivered test. For the paper-delivered test, a calculator is provided. Understanding these rules is crucial to avoid any issues on test day.
Who Needs to Know This Policy?
All GRE test-takers, especially those preparing for the Quantitative Reasoning section, need to be aware of the calculator policy. This includes:
- Students applying to graduate programs in the US and internationally.
- Individuals seeking to improve their Quantitative score.
- Anyone unsure about what testing materials are permitted.
Common Misunderstandings
Many students assume they can bring their favorite scientific or graphing calculator. However, the GRE’s policy is quite strict:
- Assumption: “My TI-84 is fine because it’s a standard scientific calculator.” Reality: Many advanced scientific and graphing calculators are prohibited due to features like programming, connectivity, and extensive memory.
- Assumption: “I’ll just use my phone calculator.” Reality: Electronic devices like smartphones, tablets, and smartwatches are strictly forbidden.
- Assumption: “A basic calculator is always allowed.” Reality: While basic arithmetic functions are permitted, the GRE provides an on-screen calculator for the computer-based test, and a physical one for the paper-based test. Bringing your own might be unnecessary and could cause confusion if it violates policy.
GRE Calculator Policy Explained
The official GRE calculator policy emphasizes that the exam is designed to test your problem-solving skills, often without reliance on advanced calculator functions. The focus is on estimation, logical reasoning, and understanding mathematical concepts.
The Built-In GRE Calculator
For the computer-delivered GRE General Test, a calculator is integrated directly into the test interface. This on-screen calculator is a four-function calculator (addition, subtraction, multiplication, division) with basic square root functionality. It’s designed to be simple and reliable, ensuring all test-takers have access to the same basic tool.
Calculator Policy for Paper-Delivered GRE
If you are taking the paper-delivered GRE (typically offered in locations where computer testing is unavailable), a four-function calculator with square root capability will be provided to you at the test center. You generally cannot bring your own calculator for this format either.
What is Generally NOT Allowed?
ETS explicitly prohibits certain types of calculators and devices to maintain test security and fairness. This includes:
- Any device with network connectivity (Wi-Fi, Bluetooth, cellular).
- Programmable calculators that can store complex formulas, programs, or extensive data.
- Calculators with a full QWERTY keyboard.
- Stylus or pen input devices.
- Audio or video playback/recording capabilities.
- Devices with displays larger than a standard calculator.
- Tablets, smartphones, smartwatches, or any other personal electronic device.
The core principle is that the GRE calculator is a tool to *assist* with calculations, not to *replace* mathematical reasoning or store pre-programmed solutions.
The Formula for Calculator Admissibility (Conceptual)
While not a mathematical formula, the GRE calculator policy can be understood through a set of criteria. Think of it as a decision tree:
Is the device a prohibited electronic gadget? (e.g., smartphone, tablet, smartwatch)
- YES: Not allowed.
- NO: Proceed to next question.
Does the device have network connectivity (Wi-Fi, Bluetooth, etc.)?
- YES: Not allowed.
- NO: Proceed to next question.
Is the device a programmable calculator capable of storing complex formulas or extensive data?
- YES: Not allowed.
- NO: Proceed to next question.
Does the device have features like a QWERTY keyboard, stylus input, audio/video capabilities, or a very large display?
- YES: Likely not allowed.
- NO: Proceed to next question.
Is it a basic four-function calculator (possibly with square root)?
- YES: Potentially allowed, but ETS provides one anyway.
- NO: Re-evaluate previous steps.
Final Decision: If your calculator passes all the ‘NO’ checks and is merely a basic arithmetic tool, it *might* be permissible. However, given ETS provides a calculator, bringing your own is generally discouraged and unnecessary. Relying on the official GRE calculator ensures compliance.

Practical Examples
Example 1: Standard Scientific Calculator
Test Taker’s Device: Texas Instruments TI-30XS MultiView (a common scientific calculator).
- Inputs:
- Calculator Type: Scientific
- Features: No connectivity, no QWERTY, no stylus, no audio/video, standard display size, limited programmability (basic function storage).
- Stored Formulas: No (beyond standard scientific functions)
Result: Likely NOT Allowed.
Reasoning: While it performs standard scientific functions, ETS typically prohibits advanced scientific calculators, especially those capable of complex function storage or equation solving beyond basic operations, to maintain fairness. It’s best to rely on the provided GRE calculator.
Recommendation: Do not bring this calculator. Use the built-in GRE calculator.
Example 2: Basic Four-Function Calculator
Test Taker’s Device: A simple, battery-operated calculator with +, -, x, /, and sqrt keys only.
- Inputs:
- Calculator Type: Basic
- Features: No connectivity, no QWERTY, no stylus, no audio/video, standard display size, no programmability.
- Stored Formulas: No
Result: Potentially Allowed, but Unnecessary.
Reasoning: This calculator meets the basic criteria of not being a prohibited device. However, since ETS provides a similar (or identical) four-function calculator within the GRE testing software (or at the test center), bringing your own is redundant and could potentially raise questions if not clearly a simple device.
Recommendation: Do not bring this calculator. Use the provided GRE calculator for a smooth test experience.
Example 3: Smartphone Calculator App
Test Taker’s Device: iPhone calculator app.
- Inputs:
- Calculator Type: Other (Smartphone App)
- Features: Network connectivity (if enabled), standard display size (relative to phone), potential for advanced functions depending on the app.
- Stored Formulas: Potentially, depending on the app.
Result: Absolutely NOT Allowed.
Reasoning: Smartphones are explicitly listed as prohibited electronic devices. Even if using only the calculator function, the device itself is banned from the testing room.
Recommendation: Leave your smartphone completely out of the testing room. Rely solely on the provided GRE calculator.

Key Factors That Affect GRE Calculator Admissibility
Several factors determine if a calculator is allowed on the GRE. Understanding these helps clarify the policy:
- Device Category: Is it a standalone calculator, or a multi-functional electronic device like a smartphone or tablet? Smartphones and tablets are universally banned.
- Connectivity: Any form of wireless communication (Wi-Fi, Bluetooth, cellular) immediately disqualifies a device. This prevents unauthorized communication or data access.
- Programmability & Memory: Calculators that can store custom programs, complex equations, or large amounts of data are disallowed. This ensures the test measures your ability to solve problems, not your ability to program a calculator.
- Input Methods: Devices with full QWERTY keyboards or stylus/pen input are typically prohibited as they can be used for note-taking or more complex data entry than intended.
- Advanced Functions: While basic scientific functions (trigonometry, logarithms) might be present on some scientific calculators, overly advanced or specialized functions that could trivialize quantitative problems are usually restricted.
- Test Format Specifics: Whether you’re taking the computer-based or paper-delivered GRE influences whether you’ll even need or be allowed a personal calculator, as ETS provides one in both cases.
