Benefits of Using a Graphing Calculator on the SAT

Matching Graphs

Instead of manually drawing graphs of functions on your scratch paper, one of the biggest benefits of the graphing calculator is simply plugging the function into your graphing calculator and choosing the graph that looks the most like the one on your calculator!

Quickly Solving Systems of Equations

The graphing calculator is also super helpful when solving systems of equations by using the INTERSECT option.

Finding Points of Intersection

When given two graphs, you can find the point of intersection using your graphing calculator. Check out this guide for how to find points of intersection using a graphing calculator. 

Converting Decimals into Fractions

We love the feature of most graphing calculators to convert decimals into fractions, saving you tons of time by converting your answer with a simple button. And better yet, it will give you the fraction in its most reduced form.

Finding Absolute Zero

For finding absolute zero on the SAT, you can use your graphing calculator. Simple select MATH and use the right arrow key to NUM and select choice: 1 abs(.) Try this function with this guide

SAT Calculator Rules

  1. Only an acceptable SAT calculator is permitted for the Math Test portion of the SAT
  2. You may not use a calculator while working on any other sections of the SAT
  3. Your calculator may not be used to share information from the test to others or after or suffer immediate dismissal
  4. You must bring your own calculator and you may not share with others

SAT Calculator Tips

1. Use your calculator as frequently as possible before entering the SAT: It’s important that you are familiar with the functions and can use it both quickly and effectively upon test day. You can use your calculator in your math classes leading up to the SAT. You can start practicing using your SAT calculator on these free official SAT practice tests!

2. Know when to use your calculator on the Math section and when not to use it. Not every question on the SAT requires a calculator to solve, and if you use it for every question, you probably will run out of time.

3. Make sure your batters are fresh on test day, as the testing center will not have backup batteries for you during the test.

4. Double check the entry line: The calculators that we recommend in this list for the SAT all have an entry line (since we don’t recommend using a four-function calculator. It’s imperative to double check what you have typed in your entry line to catch any typos, as these simple mistakes can make the difference between a high scorer and an average scorer.

Can I use my PSAT-Approved Calculator on the SAT?

If you already purchased a calculator for the PSAT, then we have some good news for you! All of the PSAT-approved calculators we recommend are allowed on the SAT.

Calculators Not Allowed on the SAT

This seems pretty obvious, but no laptops or computers, smartphones, tablets, or cell phones can act as a calculator on your SAT Math section. Here are additional criteria of calculators that are not allowed on the SAT:

  • Calculators that can access the internet, have wireless, Bluetooth, camera, cellular, and/or audio/video recording
  • Models with a typewriter-like keypad, pen option, or stylus
  • Models with electrical outlets, make noise, or paper tape
