Understand Your Needs
Several brands and models of calculators have their own list of features. Generally speaking, the higher the price, the more functionality and features you’ll get. To find the right kind, consider the types of equations and tasks you’ll do. These questions can help you select the right calculator:
What Types of Tasks Will You Do in Your Classes?
The syllabus, class description, or teacher may help you determine that. Make sure any calculator you buy can handle the calculations you’ll need it to do.
For example, basic calculators are perfect for simple arithmetic operations such as addition, subtraction, multiplication, and division. These are often sufficient for late elementary school and middle school students.
Scientific calculators, on the other hand, are useful for more complex math like trigonometry, logarithms, and scientific notation. They are typically used in upper-level middle school and high school math courses such as Algebra II, Pre-Calculus, and Chemistry.
Graphing calculators are the most advanced type. They can plot graphs, solve simultaneous equations, and perform advanced calculus. These are common requirements for high school and college-level Calculus, Statistics, and Engineering courses.
Here’s a quick breakdown to summarize:
● Basic calculators. Ideal for late elementary school and middle school math, simple personal finance tasks, and everyday arithmetic.
● Scientific calculators. Necessary for high school and some middle school math and science courses, including Algebra II, Geometry, Trigonometry, and Chemistry.
● Graphing calculators. Required for advanced high school and college courses such as Calculus, Statistics, Physics, and Engineering.
Understanding the types of tasks you’ll be performing in your classes can guide you to the right calculator choice. Always refer to your course requirements to make sure your calculator meets the specifications.
Will You Need to Use the Calculator for a Specific Exam?
Standardized tests, such as AP tests and the SAT, often allow calculator use, but only certain models. Be sure to check the SAT Calculator policy for acceptable calculator models and other rules for calculator use. For AP exams, also refer to the AP Exams Calculator Policy.
Will You Need the Calculator for Future Classes?
You may need a more sophisticated calculator if you plan to take more advanced math, science, and engineering classes. Buying a more advanced calculator now could make sense, so you don’t have to upgrade in a year or two.

Consider the Extra Features
Choosing the right calculator doesn’t completely boil down to need. Additional features might be worth spending extra money on to make your experience more efficient and enjoyable.
For example, some graphing calculators — like the TI-84 Plus CE Color Graphing Calculator — include full-color screens, making graphs easier to read and allowing for color coding. Some graphing calculators — like TI-84 Calculators — also come with preloaded applications that could be useful, depending on the calculations or tasks.
Some features you might want to consider include:
● Adjustable screen contrast, allowing you to dim or brighten your screen as needed
● Storage of past calculations you’ve performed so you can review them later
● Ability to quickly translate fractions into decimals and vice versa
● Ability to input equations in proper notation and how they appear in, say, a textbook
● A manufacturer’s warranty that covers you if the calculator malfunctions in the first year or beyond
● A color screen to help you differentiate between graph linesSpecialty Calculators
Also, consider how the calculator is powered. Some require disposable alkaline batteries, such as AAAs, but many now include rechargeable batteries or run on solar power. Not worrying about buying and replacing calculator batteries can be a big relief.
