The 2025 school year is officially in session. Whether you’re a student or you just sent one back to the classroom, it’s a good idea to make sure to grab the best calculator for both math and science classes. Though the calculator on your phone can do a lot, it isn’t suitable for every single assignment. For those more complicated equations, you or your student will undoubtedly need a graphing calculator. That’s why you should add one (and one of several other top-rated calculators) to your back-to-school shopping list.
You might think that getting a calculator is one of the simpler purchases you could make, but there are quite a few options. And they aren’t all built the same, nor do they all come with the same features. Some “complex” calculators may look like they do everything you need, but they might lack a specific function. And some are less complicated than others. High-school math students will likely need a graphing calculator, while other specialized classes may require a scientific calculator. It all depends on what the class requires.
One important factor to consider when shopping for a calculator is that not all of them can be used during standardized tests. We recommend reviewing the updated 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.)
Best calculators for students in 2024
Back-to-school shopping can be frustrating enough. That’s why we put together a selection of the top-rated calculators that you can shop right now. Of course, it is a good idea to double-check your school supplies list or syllabi to make sure that the calculator you buy meets class requirements. If there are none, these offer a good baseline to start with.
Whether you’re looking for a scientific calculator for lab classes or a graphing calculator that can be used on standardized math tests, there are plenty of picks below, organized by grade and purpose. Several are on sale now with some hefty back-to-school discounts, so be sure and grab them while you can.
