GRE Calculator
Free interactive simulator based on ETS's on-screen GRE calculator for Quantitative Reasoning.
If you want to get faster and calmer on GRE Quant, you should practice with the calculator you will actually see on test day.
That is the purpose of this page.
This free tool is an interactive GRE calculator simulator built around ETS's official on-screen calculator guidance for the Quantitative Reasoning measure.

Hands-down the best affordable prep course for the GRE.
TESTPREPPALWhat This GRE Tool Is For
This is not a score calculator.
It is a practice simulator for the on-screen calculator used on the GRE General Test's Quantitative Reasoning section.
That means you can rehearse:
- long division
- square roots
- multi-step arithmetic
- parentheses and order of operations
- memory-key usage
- numeric entry transfer behavior
Official ETS Sources Used
We built this tool from ETS's official GRE calculator materials:
- GRE Guidelines to Using the On-screen Calculator (ETS PDF)
- GRE Quantitative Reasoning Overview
- POWERPREP Online Practice Tests
What ETS Says About The GRE Calculator
According to ETS:
- the calculator is available in the Quantitative Reasoning measure
- it is best used for tedious computations, such as long division and square roots
- it should not replace mathematical reasoning or quick mental math
- it respects order of operations
- it includes Transfer Display
- it has one memory location controlled by MR, MC, and M+
ETS also notes that:
- division by zero produces ERROR
- taking the square root of a negative number produces ERROR
- the display supports up to eight digits
Why Practicing With The GRE Calculator Matters
The GRE calculator is basic, but that does not mean it is irrelevant.
Candidates often lose time because they:
- overuse the calculator on easy arithmetic
- mistype during longer computations
- forget order-of-operations behavior
- have never practiced the memory buttons
Using a simulator helps fix all four problems before test day.
How To Use This Simulator
- Work through a few GRE Quant problems while using only this calculator.
- Practice when to calculate and when to estimate mentally.
- Try the Transfer Display button with the mock numeric-entry field.
- Practice basic workflows with MR, MC, and M+.
What This Simulator Includes
- a GRE-style keypad layout
- MR, MC, and M+
- C and CE
- parentheses
- square root
- plus-minus toggle
- decimal input
- Transfer Display
Important Limitation
This tool is a practice simulator, not ETS software itself.
It is designed to reflect the official button set and behavior ETS describes, but your actual test interface is still the final source of truth.
FAQ
Do you get a calculator on every GRE math question?
You get access to the on-screen calculator in the Quantitative Reasoning measure, but ETS still recommends using it selectively.
Is the GRE calculator the same as a normal basic calculator?
Not exactly. ETS specifically notes that the GRE calculator respects order of operations, while some basic calculators compute operations strictly in the order entered.
What is the best way to practice with the GRE calculator?
Use it only on questions where the arithmetic is genuinely tedious, and avoid relying on it for simple computations you should do mentally.
