Best Graphing Calculator

Graphing calculators have become a staple in math classes around the world, particularly in high schools and colleges. This type of calculator helps students understand mathematical and scientific concepts better. From algebra to calculus, a graphing calculator will help you create graphs with ease. This article provides a list of the best graphing calculators available on the market today. You can study and compare the various models and brands on the list, so you will eventually purchase the graphing calculator that will best suit your needs.


What to Look For

There are several major factors to consider when looking for the best graphing calculators, including ease of use and longevity. Graphing calculators that are outdated, fragile, and confusing will not last long enough in the hands of students. Below are the four most important features that you need to take note when it comes to finding the best graphing calculators.



You need to consider the technical aspects of this computing device, such as input styles, screen resolution, read-only memory (ROM), and the random-access memory (RAM). Most calculators use the algebraic input style, but some models use the Reverse Polish Notation (RPN). It is important to search for a fast RAM for quick graphing and calculation.



The calculator must be durable enough to withstand the weight of the bag. Make sure that the calculator that you will choose can do various mathematical functions and withstand the constantly rough treatment. It is also necessary to check whether the calculator is compatible with the test that you will take.


Ease of Use

The best graphing calculator is easy to use and has an ergonomic design. It should come with user-friendly buttons and the functions must be within reach. This means certain math formulas should be easily accessible, and not under multiple menus. The display should also make it easier for you to read the data.



Graphing calculators can be complicated. It is crucial to have a documentations and manuals with extensive information to help you perform specific computing tasks. You also need to check if the manufacturer offers efficient and effective customer support, whether online, via email, or through phone. Most calculators come with a one-year limited warranty.


You need graphing calculators to help make your math life easier. The list below are top rated graphing calculators with solid features, are durable, and have extensive customer support.

Casio ClassPad330

The ClassPad330 is filled with extremely helpful features, including a powerful Computer Algebra System (CAS) that makes programming easier. You can write the programs to solve mathematical equations. You can also use the programming language for basic and advanced mathematical questions, from algebraic functions to differential calculus.

The stylus allows you to navigate the large screen, but is slightly smaller than the regular pen. It should be noted, however, that the ClassPad330 is only helpful outside the classroom. This calculator is banned on major tests and in many schools.



This graphing calculator has a noticeably smaller screen, but features a high-contrast display to make it readable. It also has one of the largest storage capacities on the list. While the unit has a low amount of RAM, customers have no complaints about its processing speed. The device is compatible with nearly every subject, except linear algebra.
