Things to Consider Before Purchasing the graphing Calculator

Buying a calculator is not a rocket science and you don’t need to look for much before settling on a particular model. Below are a few important things that I think you should look into before buying any calculator.

The Key things you need in a graphing calculator.

The mathematical computing abilities

The first thing to look for before buying a calculator is to check whether or not it has all the mathematical capabilities you need. Fortunately for you, unless you are working on a really high-level technical job. A basic graphing calculator will suffice for all your needs. You don’t need to look much deep for this.

Speed of processing

Higher processing speed is always better. This metric tells you how fast a calculator performs a calculation. Most calculators listed below are pretty fast.

Ease of use

User friendliness is subjective and the best way to know about user friendliness about a particular calculator is to read the reviews from previous customers. In general, an intuitive design and layout with a good keyboard is the key to user-friendliness.


Calculators come in many different types of screens and screen sizes. You will need to choose according to your budget and your use. There are small screen calculators, large screen ones, back-lit, hi-resolution as well as color screens. Each calculator varies in prices and features.


The price of the calculator is an important factor too. In the calculator world, the more expensive ones aren’t necessarily better. Therefore comparing the price to value ratio of each calculator is a good idea.


The size and the type of memory you calculator has is an important factor. A more memory a calculator has, the more equations you will be able to save. For some highly technical jobs, more memory is a pre-requisite.


Finally, take a look at the warranty of the calculator before making the purchase. Most calculators provide one year warranty but it’s a good idea to confirm it once.

Frequently Asked Questions

Q: Which brand should I buy?

Texas Instruments is one of the most popular brands. Casio comes a distant second. Those two brands are the most reliable ones.

Q: What’s a scientific calculator or graphing calculator?

A graphing calculator is just a scientific calculator but with the additional feature of equation graphing. But graphing calculators are generally more advanced than scientific calculators. If you are a student, there are two conditions in which you a graphing calculator is an ideal choice.

1.You are a student above 9th grade

2.Your course does not disallow graphing function.

In general, a graphing calculator is useful for algebras (all levels), geometry, calculus and Pre-calculus, finance, business, stats, physics, biology, and trigonometry courses.

Q: CAS or Non-CAS calculator, which should I buy?

CAS means computer algebra system. A CAS calculator can essentially manipulate variables symbolically and solve complex equations and return the answer in symbolic form. A non-CAS calculator, on the other hand, can only work with numbers and fractions and it will deal with the equations in the numeric form.

If you are a student, it is better to use a Non-CAS calculator. The reason being, as a student it is more important to understand the process of finding solutions rather than the solutions themselves.

A CAS calculator, on the other hand, is useful if you are a researcher or professional in some science or engineering
Q: Should I buy one with regular batteries or rechargeable ones?

Rechargeable batteries are preferred by many people because they are longer lasting. But I prefer regular alkaline batteries, especially if you want to buy a calculator for the sat test. Imagine, having a big test and you forgot to charge your sat calculator that day. You don’t want that to happen, do you?

Final Verdict

These are some of the thoughts on buying the best calculator and the reviews of Top 10 graphing calculators available in the market. I have taken care to make this list as exhaustive and as detailed as possible while avoiding unimportant information that you don’t need.

Now that you know almost everything you need to know to buy a graphing calculator, go ahead and pick any one calculator from the above list. These are the best ones you will find on the internet.
