How to Pick the Right SAT Calculator

Before you go on a buying spree, be aware that you cannot just buy any calculator. College Board, the non-profit organization that developed and administers the SATs and other standardized tests for students, has a list of allowed and prohibited calculators for the actual test. 

To know what to buy and what not to buy, here are frequently asked questions about the SAT math section and SAT calculator.

So what calculators are allowed on the SAT?

Generally, most graphing calculators and scientific calculators are allowed on the SAT, as long as they are handheld and do not require a battery or power cords to function. This means you cannot use your laptop, tablet, cell phones, smartwatches, and other battery-operated gadgets even if they had an effective calculator function. If your calculator has paper tape, makes noise, or requires an electrical outlet to function, it is not allowed.

All four-function calculators may also be used, but the College Board doesn’t recommend using them, so if you a choice, skip four-function for another type of officially approved calculator.

As an upgrade of the well-loved Casio fx-9860GII, this newer fx-9860GIII will make a lot of students and teachers fall in love once more.

Compared to the older Casio fx-9860GII, the updated graphing calculator has a smaller form factor and does not come with a backlight. Aside from these two, all other functions are upgraded. For example, the fx-9860GIII can now copy previous answers into the command line (similar to the popular TI-84 functionality).

Another Texas Instruments entry on this list, and it's well deserved. This TI Nspire CX Cas graphing calculator is more advanced than the famous TI 84. It features licensed TI-Inspire CX CAS Student Software, which provides enhanced graphing capabilities and other advanced calculator functionality. You get your money's worth just for this software alone.

But this graphing calculator is so much more. It has a 320x240 pixel screen size with 16-bit color and 125DPI screen resolution. You get six different graph styles and 15 colors to assign each graph drawn.

The Casio PRIZM FX-CG50 may look smaller than other calculators for the SAT that I featured here, but I guarantee you it is one of the best Casio models to help you pass any standard exam. 

Casio PRIZM FX-CG50 is a full-featured graphing calculator.  In geometry, it tells you the max, min, left/right boundaries, and other data without the guesswork, so you could save time and get on with your calculations.

Used for high school, college, and beyond, this Casio model can get you through advanced algebra, differential equations, calculus, and more.

  • Completely intuitive and user-friendly interface
  • Bright color backlit screen
  • More affordable than others on this list
  • Low battery consumption

Things We Didn't Like

  • Needs 4 AA batteries (takes a long time for this to require replacement, but can be a deal-breaker if you’re interested in rechargeable calculators)


The main difference between this Texas Instruments TI 89 calculator and the first one on this list is that this one has CAS functionality, split-screen design, and the Program Editor, which lets you write your own custom apps into the device. 

 Like any other graphing calculator with CAS, this model is capable of producing symbolic results, manipulating algebraic expressions, and performing operations such as factor, expand, and simplify.

The TI-89 Titanium comes pre-loaded with sixteen graphing calculator software apps, including EE*Pro, CellSheet, and NoteFolio.  It can handle calculus, algebra, matrices, and statistical functions quickly.

Do you have to clear your calculator for the SAT?

Students are not required to clear the memory of their calculators. This is because you must bring your own calculator. Anyone who takes the SAT cannot share his or her calculator with co-examinees.

What calculators are not allowed at the SATs?

Some calculators are actually not permitted. For example, your calculator is not permitted if it has a QWERTY keypad, keypad pen, stylus, or pen-input. The calculator you choose also cannot access the internet, play games, download apps, or have the capability of audio-video recording.

If your calculator has a raised display or any design that makes it visible to other test-takers seated near you, the test coordinator might ask you to move to another seat.   

Can you take the SAT without a calculator?

You can answer all the math problems even without an SAT calculator. However, about half of the SAT math section would be easier to answer if you use your calculator. Imagine how much time you'd be saving if you're used to solving problems on a calculator.

Even though students can take the SAT test without using a calculator, your best chance at completing the SAT on time and with high scores is to use a calculator that you've used for months or years.

One important thing to note about bringing a calculator is that never bring a brand-new calculator to the exam. The SAT isn't the time to explore the many functions of your Casio fx 9750gii or any other brand.

It wouldn't matter if you brought the Casio fx 9750gii, TI Nspire cx CAS, TI 89 Titanium, or one of the best calculators in the market if you do not know how to use it during the exam.  Operating these kinds of calculators has a steep learning curve, so I recommend you practice using them months or years before test day. 

Wrap Up: Which one is the Best SAT Calculator?

If you've already finished studying and are just waiting for your scheduled date, make sure you come prepared with only the best calculators for the SAT.  I can't sway you to pick the Casio FX 9750gii or the uber-popular TI 84, mainly because there isn't a single calculator for everyone. The best SAT calculators for you (who is just going to use this tool for the SAT) might not be the best for your friend who is planning to study advanced math in college after taking the SATs.

Choose one calculator from the list of 7 I highly recommended above and you're halfway there. All you just need to do is break a leg on the actual SAT test day, use your chosen calculator to answer the mathematics section, and finish on time.
