What Are The Best Calculators for the SAT? (2022)

Best Calculator for SAT Reviews

The SAT is a college admission test for high school students. There are three sections: Math, Reading, Writing & Language, and an optional Essay section. For the Math portion, you have areas where a calculator is permitted and some that it is not.

There are regulations on which kind of calculator is acceptable, and there’s a list of devices you cannot use. With so many options, it can get challenging to decide which one to pick. They all have various capabilities, and you don’t want something too basic or too complicated.

No worries, we’ve put together an excellent selection to help you out so that you’re well-prepared to tackle the SAT. Based on your budget and preferences, you’ll no doubt find the perfect calculator below.

Should I Use a Calculator on the Test?

We suggest that you go with a graphing calculator on the test. Based on the company, student recommendations, and educator expertise, we’ve compiled a list of the best calculators out there. Using a calculator on the sections where allowed may help you move along quicker, as time is of the essence when you’re taking the SAT.

Another pro tip is to practice using that calculator beforehand. There are plenty of SAT prep exams that you can take, and you should do them with the calculator you intend to use for the test. You don’t want to be unfamiliar with the device and trying to figure it out while taking the SAT.

For each problem, decide if you actually need the calculator, as each problem is designed to be solved without one. If you can figure the answer out relatively quickly without using the calculator, do it that way. Otherwise, use the calculator efficiently.

Despite this, the performance is outstanding. It packs all of the best features plus a few extra.

It has a recharging feature that ensures your calculator won’t die during the exam. There aren’t any battery replacements to fumble around with, as a single charge can last you for two weeks. There’s also a backlight feature so that you can still view the screen in dim lighting or at nighttime.

The CAS, or Computer Algebraic system, automatically checks limits and efficiently performs the algebraic functions.

Those handling Texas Instruments calculators are more likely to notice the difference in lighting right away, in which case you may not appreciate the lighting. The display can show seven rows and twenty-one characters at a time; this display is sufficient to handle most SAT questions.

Because most of the power is devoted towards calculations, it’s safe to say that the processing speed is as good as it gets. The basic screen means that the calculator is not tasked with powering many pixels.

However, there’s one legitimate complaint that some of the abbreviations on the menu can be tedious to read through at times. Unfortunately, the number of applications is limited to just 14, which is not very impressive. Most applications can perform simple calculations and graphs except for Computer Algebra System or CAS.

Here are some of the leading apps: matrices, simultaneous equations, lists, tables, graphing, and more. This particular model does not return square roots and trigonometric values as decimals instead of simplified figures or exact values. You quickly access the primary language and key combination by going to the mini menu. It will take some time for people not familiar with this calculator brand to get used to the abbreviations.

The calculator is very sleek and designed ergonomically for a firm grip. Moreover, the buttons are all arranged in a way that makes sense, and all of them have a pleasant tactile feel to them. Four AAA batteries power this calculator, and they are not rechargeable batteries. It comes with a USB port to seamlessly upload apps and data to your PC.

SAT Calculator Checklist

  • If you think that there’s a possibility that you’ll need a calculator, you should bring one anyway. You cannot share calculators during the exam

  • Never use a calculator during the no calculator portion of the exam, or your test may be disqualified.

  • Be sure to use the calculator that you’ve practiced with. You do not want to fumble around with an unfamiliar calculator; this can negatively impact you on test day.

  • If you have a rechargeable calculator, be sure to fully charge it the night before your test. If your calculator is non-rechargeable, make sure you use new batteries. You will be unable to charge your calculator during the exam.

  • If you have the ability, bring an extra calculator in case of an emergency. Also, it is possible to bring extra batteries.

  • Check the entry line on the calculator for any typos

  • Do not waste your time checking each answer when you come across a question that you can complete without a calculator. Wait until you’ve completed the test and if you have spare time, go back and check your answers.


You can rest assured that if you have a Texas Instrument or Casio calculator, you’ll be good to go. This is especially true because these two calculator manufacturers dominate the SAT calculator market.

Keep in mind that there is not one calculator that fulfills the criteria for every standardized test like the SAT, PSAT, or ACT. Each standardized test has its own set of rules, and each student must abide by them. Feel free to ask your professors or even your peers to choose which of these calculators is ideal for you.
