The Best Graphing Calculators

What to Consider

Graphing calculators have more advanced capabilities for higher-level math than scientific calculators typically do, with larger, more dynamic screens for graphing functions and plotting coordinates. Before you start shopping, it’s essential to consider the age of the individual you're buying for and their grade in school, if applicable.

There are graphic calculators that can take a student from middle school pre-algebra all the way to calculus, but younger kids may be overwhelmed by having too many features at their disposal, while higher-level math students may learn better on a calculator specifically designed for advanced concepts rather than a basic model that skims the surface.

You may want to go with something that aligns specifically with what your child will be learning. Also, particularly for students in lower grades, teachers may recommend using a specific brand and model. For older high school students, keep in mind that certain calculators are accepted for various AP and college entrance exams and others are not, plus some models may be better suited to specific tests.

Graphing calculators have either black and white or color LCD displays, many have rechargeable batteries and offer USB connectivity, and some come pre-loaded with apps.
