When it comes to selecting the best calculator for the ACT, it is not about picking the most expensive model. It is about picking one that helps you work faster, avoid mistakes, and stay calm during the test.
The ACT Math section has 60 questions that you must finish in 60 minutes. While every problem can technically be solved by hand, the clock is your biggest enemy. Using the best calculator for the ACT isn't just about doing basic math; it is about saving time so you don't have to rush through the difficult questions at the end.
So, let us look at some of the best calculators for ACT, how to choose between the options, and what mistakes to avoid.
Why Your Calculator Choice is a Game Changer?
The Math section makes up 25% of your total score. To get into a great college, you need a high score, but many students struggle to finish on time. As per research, it has been found that students who are overly dependent on calculators on average score 2 points lower compared to those who are not.
Here is why calculators really need to be used:
- Graph complex equations in seconds.
- Avoid "silly" mistakes with multiplication or division.
- Check your work visually to make sure your answer makes sense.
What Calculator Can You Use on the ACT? (The Rules)
Before you buy a fancy new gadget, you must know which calculator functions are permitted. If you bring the wrong one, the testing center will take it away, or worse, cancel your entire test score.
The "CAS" Rule
The ACT has a very strict rule against "Computer Algebra Systems" (CAS). A CAS calculator can solve for "x" automatically. The ACT wants to test your algebra skills, not the calculator's skills.
Prohibited Calculators
- TI-89 and TI-92: These are very popular for Calculus, but they are banned because they have CAS.
- TI-Nspire CAS: Look closely at the top right of the calculator. If it says "CAS," leave it at home.
- HP Prime: This is a powerful tool, but it is not on ACT's list of approved calculators.
- Laptops or Phones: You can never use a phone, tablet, or laptop as a calculator.
If you bring an unapproved device, you may not be allowed to use it. That is why understanding what calculator you can use on the ACT is critical.

What are the Features You Should Look for in the Best Calculator for ACT?
Selecting the best calculator for ACT is a strategic decision that can directly impact your speed and accuracy on test day. While the ACT allows a wide range of devices, the most effective ones share specific features that help you navigate the 60 questions in 60 minutes efficiently.
1. High-Resolution Graphing Display
A graphing calculator is highly recommended over a scientific one because it allows you to visualize equations. Look for a model with a high-resolution color screen, which makes it much easier to distinguish between multiple functions or find points of intersection.
2. MathPrint Technology
The best calculator for ACT is essentially the one that features MathPrint, as it can display fractions, exponents, and square roots exactly as they appear in your textbook or test booklet. This is quite helpful when it comes to reducing entry errors.
3. Advanced Statistical Functions
The ACT exam tests data analysis, including mean, median, standard deviation, and regression lines. A calculator that comes with a dedicated "Stat" menu allows you to input a list of data and get all these values instantly.
4. Non-CAS Compliance (The "Golden Rule")
This is one of the most important technical requirements. Your calculator must not have a Computer Algebra System (CAS). A CAS can solve algebraic equations symbolically (solving for "x"), which is not allowed by the ACT.
5. Reliable Battery Life
ACT sessions are long, and the last thing you want is a dead device. Look for calculators with rechargeable batteries and a clear battery level indicator.
Helpful Tips for Using Approved Calculators for ACT
Simply having the best calculator for the ACT isn't enough. You need to be a pro at using it.
- Charge it Up
There are no outlets in the testing room. If your battery dies, you are on your own. Make sure to charge your calculator the night before. If your model uses AAA batteries, put fresh ones in before the test.
- Don't Over-Rely on It
Even with the ACT permitted calculators, you shouldn't use them for every single problem. If a question asks "What is 5×6?", your brain is faster than your fingers. Use the calculator for the "heavy lifting" like trigonometry or big decimals.
- Learn the Shortcuts
Most approved calculators for ACT have shortcuts for things like changing a decimal into a fraction. Knowing these small tricks can save you 5 to 10 seconds per question. Over 60 questions, which adds up to 10 extra minutes!
Common Mistakes Students Make
Even when you have the best calculator for ACT success in your bag, having the tool is only half the battle. Many students fall into avoidable traps that can cost them precious points and minutes. To make sure that you are making the most of your approved calculators for ACT, avoid these frequent pitfalls:
- Do not use a new calculator right before the test day,

It is important to fix these mistakes as they can help you improve your score quickly.
