What to Look for in Graphing Calculators


Chances are if you’re buying a graphing calculator, it’s because your teacher or professor said you needed one. They may recommend the best model for your course, and you can also check College Board to see which models are approved for use on SAT and AP exams. Use your course and exam requirements as a guide, but if you plan to continue your mathematics studies, it may be worth going for a more advanced model.

Screen Display

It's important to consider the size and clarity of a calculator's display—some have color screens while others are black and white, and more advanced models display 3D graphs and real images.

Advanced Features

If you plan to study advanced math and engineering, you may want to choose a calculator that has additional applications such as making spreadsheets, creating documents, or importing images.

Battery Life

Some models can be charged or connected by USB to other devices, while others are typically powered by four AAA batteries or rechargeable batteries.


As long as your calculator performs the functions you need for your class (or your job), you don’t necessarily need to go with the most expensive one. If you're going to use it long-term, however, it may be worth investing in a more advanced model, so you don’t have to replace a cheaper version every year.


What exactly is a graphing calculator?

Graphing calculators offer all of the basic calculation options of a regular calculator, along with a display screen that can plot graphs and perform complex equations. They are different from scientific calculators, which can also handle some complex equations in that they have graphing capabilities.

Why are graphing calculators expensive?

For starters, graphing calculators feature more bells and whistles than scientific or other calculators. Still, they never really dropped in price as older technologies typically do. What’s more, there are free graphing calculators online today, so how could graphing calculators still command expensive prices? The answer: it has more to do with economics and business practices than with the price of technology. Because graphing calculators are still required in most high school and college-level mathematics courses, as well as the SAT and other state exams (where you can only bring an approved device), there is still a huge demand for them. That means manufacturers can keep the prices up.

Which is better: Texas Instruments or Casio?

Texas Instruments (TI) is an American company founded in 1930 and Casio was launched in Japan in 1957, with the latter being the first to market with a graphing calculator. While TI is the market leader (some might even call it a monopoly), choosing which brand to go with comes down to personal preference. For math students, though, you can’t go wrong with either as they both offer different outstanding calculators at various price points that will appeal to students of all levels. However, don’t be surprised if your teacher or professor recommends TI models just because they are the most well-known.
