You might think that getting a calculator is one of the simpler purchases on your back-to-school list, but there are actually quite a few options. High-school math students will likely need a graphing calculator, while other specialized classes may require a scientific calculator.

One important factor to consider when shopping for a calculator: Not all of them can be used during standardized tests. We recommend reviewing the updated 2023 AP Exams calculator policy and the SAT calculator policy before you buy. (In general, most scientific and graphing calculators are permitted so long as they don't have a QWERTY keypad or wireless communication capabilities.)

To help simplify your back-to-school shopping, we've compiled a list of the top-rated calculators. These calculators have received rave reviews from parents, teachers and students online. Of course, it is a good idea to double-check your school supplies list or syllabi to make sure that you are buying a calculator that meets teacher requirements.
