What Calculator Can You Use on the GED? An Official Guide
The rules about what calculator you can use on the GED are very strict. You cannot bring your own calculator to the testing center unless it is a specific model, and for online tests, you must use the on-screen version provided. This tool helps you determine the exact calculator policy for your specific test section.

Rules can vary slightly depending on where you take the test.
What is the Official GED Calculator Policy?
When you ask “what calculator can you use on the GED,” the answer is simple and strict: the **Texas Instruments TI-30XS MultiView™ scientific calculator**. This is the only calculator model allowed for use on the GED test. The GED Testing Service has standardized this to ensure fairness and to prevent the use of more advanced calculators with stored formulas or graphing capabilities.
For most students, you won’t need to purchase one. An on-screen version of the TI-30XS is provided directly within the test interface for the sections that allow it. If you are taking the test at a center, they may provide a physical, hand-held version. It’s crucial to understand that you cannot bring your own different model (like a graphing calculator or phone calculator) into the testing room.
The Official Calculator: TI-30XS MultiView™
The TI-30XS is a powerful scientific calculator chosen for the GED because it includes all the necessary functions without being overly complex. It’s designed to handle everything from basic arithmetic to more advanced scientific notation and trigonometry. You don’t need to know every function, but familiarity with the basics is key.
There is no “formula” for the calculator itself, but it has functions essential for solving formulas given on the test. Knowing how to use these features is a core part of preparing for the quantitative sections of the GED.
| Feature | Description | Usefulness on the GED |
|---|---|---|
| MathPrint™ Feature | Displays calculations, like fractions and square roots, as they appear in textbooks. | Extremely useful for reducing errors and entering complex problems easily. |
| Fractions | Easily enter and compute with fractions and mixed numbers. | Essential for many math problems involving ratios and proportions. |
| Powers and Roots | Calculate squares, cubes, and other exponents and roots. | Necessary for geometry (area, volume) and algebra problems. |
| Toggle Key | Switches answers between fraction and decimal form. | Helps match your answer to the format of the multiple-choice options. |
| Statistics | One- and two-variable statistics. | Helpful for data analysis questions on the Math, Science, and Social Studies tests. |
Practical Examples
Example 1: Mathematical Reasoning
A question asks you to find the volume of a cylinder with a radius of 3 cm and a height of 10 cm. The formula V = πr²h is provided.
- Inputs on TI-30XS: You would press the keys for π, then multiplication, then 3, then the x² key, then multiplication, then 10.
- Result: The calculator would display an answer of approximately 282.74, which you would use to select the correct option.
Example 2: Science Test
A problem requires you to calculate population density. A town of 1,250 people lives in an area of 2.5 square miles.
- Inputs on TI-30XS: You would enter 1250, then the division key, then 2.5.
- Result: The calculator shows 500. This means the density is 500 people per square mile. The calculator helps avoid simple arithmetic errors under pressure.

Key Factors That Affect GED Calculator Use
- Test Section: This is the most important factor. No calculator is permitted on the Reasoning Through Language Arts (RLA) test.
- Test Format: If you test online, you have no choice but to use the on-screen TI-30XS. If you test in person, you can often bring your own hand-held TI-30XS, but it’s wise to check with the testing center first.
- Familiarity: Your performance is affected by how well you know the calculator. Wasting time trying to find functions during the exam can cost you valuable points. Practice is essential.
- Order of Operations: The TI-30XS correctly follows the order of operations (PEMDAS). Understanding this helps you enter complex expressions correctly.
- Clearing the Memory: Always clear the calculator before starting a new problem to avoid carrying over previous numbers.
- Battery/Power: While the on-screen version never runs out of power, if you bring a physical one, ensure it has fresh batteries. The TI-30XS is often solar-powered with a battery backup.
Frequently Asked Questions (FAQ)
