If you or your kids are preparing for an advanced math or science course, you’re going to need a graphing calculator. These handy machines can process complex calculations (and simple ones), including graphing multiple equations at once, all displayed on the large screen. They can even store important equations and help you learn topics like trigonometry.

These mini computers cost more than the scientific calculators you’ve used in earlier math classes, but they’re capable of so much more—including downloading apps and processing 3D figures—and they’re a necessity for many math classes.

If you can’t afford to spend upwards of $100, or don’t want to invest just for one class, don’t fret. There are free, online graphing calculators like this one from Desmos—but you’ll realize quickly that having a physical calculator is much more efficient for frequent use.

These are the best tools to crunch numbers and solve equations with and without gridlines. Whether you’re studying math in middle school or college, tuck one of these in your backpack for the school season.

Check out our picks for the best calculators, writing tablets, and laptop backpacks for more back-to-school supplies.

The Best Graphing Calculators

What to Consider

Graphing calculators have more advanced capabilities for higher-level math than scientific calculators, with larger, more dynamic screens for graphing functions and plotting coordinates. Some graphing calculators can take a student from middle school pre-algebra through to college calculus, but younger kids may be overwhelmed by having too many features at their disposal—plus graphing calculators are heavier than scientific calculators.

Teachers may recommend using a specific brand and model of graphing calculator, particularly for students in lower grades. For older high school students, remember that only certain calculators are accepted for various AP and college entrance exams. Consult College Board’s official website for a list of approved graphing calculators for AP exams.

Graphing calculators feature either black-and-white or color LCD screens, the latter of which is a nice (but not always necessary) upgrade. Many have rechargeable batteries and offer USB connectivity for downloading functions or apps, while others come pre-loaded with extra apps. All of the graphing calculators we recommend come ready to use for most math classes, but you should check your syllabus to see if you need any extra features.

How We Selected

To find the best graphing calculators, we combed through customer reviews and consulted expert sources. We considered our own schooling experiences with graphing calculators as well. We included a range of calculators to suit students at different grades, from middle school to college, plus models that span various price points, and with color and black-and-white displays. We also compared and highlighted features for every graphing calculator.

Pros
  • Solid features overall

This reasonably priced, versatile graphing calculator offers excellent value and is a solid choice for high school students.

The calculator offers 14-digit accuracy and 10 graphing functions, plus you can save and work on up to 10 graphs simultaneously.
