3 Best Graphing Calculators of 2019

Graphing calculators are great to have around for a variety of reasons. They are capable of performing the most basic of mathematic functions. They simplify the computation of equations that are too complicated to be performed by hand. They are used by engineers, scientists, mathematicians, students of all grade levels, and others who possess curious minds.

Top Pick

Texas Instruments Nspire CX CAS Graphing Calculator

  • Color screen
  • Feature rich
  • Rechargable
  • Lower battery life than TI-84


Here is a list of 3 of the best graphing calculators that will start your year off right by helping you solve the most daunting of math equations.

Texas Instruments Nspire CX CAS Graphing Calculator

  • Color screen
  • Feature rich
  • Rechargable
  • Lower battery life than TI-84

The Texas Instrument Nspire CX CAS allows for the successful completion of work present in advanced high school classes, college courses, and professional fields. It has been recognized as especially beneficial to those involved in engineering, whether it be engineering courses or the profession itself.

The interactive nature of this calculator allows you to import images and label them with equations. Additionally, the buttons allow you to enter equations as they appear in textbooks. No carets or unnecessary parentheses will crowd your view. You’ll only see the equation as it is meant to appear, and in color! This will simplify and highlight the complicated equations and graphs present in an engineer’s line of work.

The use of this calculator requires a strong command over abstract concepts found in higher levels of math and science. Its number of features aren’t necessary for everyone to have and it can be a learning curve to operate this calculator to your advantage.

However, it is worth the investment to those who need a CAS (computational algebra system) that allows for the efficient manipulation of any provided equation.

It’s important to note that the Nspire is very feature-rich, so younger students looking for a calculator should be aware of this product’s prohibition from standardized testing rooms. However, it is great for stimulating the critical thinking associated with higher level math.


Texas Instruments TI-83 Plus Graphing Calculator

  • Great for High School math
  • Long battery life
  • No color screen

This calculator is ideal for those looking for a simpler interface. It is perfect for anyone in a high school setting. Students in basic algebra, trigonometry, calculus, or physics can benefit from this calculator’s functions. It allows users to graph functions, compare several functions, and plot and analyze sets of data.

Extra symbols, to include carets and parentheses, have to be manually inputted by the user. This can sometimes result in the improper relaying of information and incorrect outcomes. Additional attention and understanding of proper notation must be implemented when using this calculator.

The TI-83 Plus, starts at a lower price range than the NSpire and may not seem as sophisticated, however this calculator is compatible with its more advanced TI-84 Plus and TI-84 Plus Silver Edition models. If you ever decide to upgrade, you can be rest assured the information on your TI-83 Plus will smoothly transfer over.

This calculator can be safely used on standardized tests common in high schools. Its functions are more than adequate in entry-level college courses. It may be difficult to keep up in advanced engineering courses with this calculator because of its simplistic design, so opt for one like the Nspire if engineering (or another math-heavy professional field) is your pursuit.


Casio fx-9860GII Graphing Calculator

  • Great value
  • Awesome spreadsheet functionality
  • Comes with multiple programs installed
  • Not as commonly used in schools

 The Casio fx-9860GII is suitable for use by those in most high school level math and science courses. It is especially useful in calculus and business courses. This calculator has the most usefulness to a wide range of math users.

It comes equipped with easily accessible special programs to complete complicated mathematical procedures like conics. There is no need to download these programs, unlike the TI interface.

A unique aspect of this calculator is its spreadsheet application. This application is built-in and allows for an easy way to organize overwhelming information found in calculus and finance courses.

It can be used on AP and college entrance exams, and is quick at processing your inputs. The Casio system isn’t as prevalent in high schools as the TI system is, but the Casio interface is easily learned and understood through outside resources. A lot of learning is completed on your own, especially in college, so this issue shouldn’t stop you from making this Casio purchase.



Graphing calculators come in a variety of types. They present their displays different, complete different functions, and cater to different subjects of math. Selecting the right one for your needs is easy with the right background information!
