# The Best Calculators for the ACT

According to the ACT officials, all the ACT math problems may be solved without a calculator. But it’s the height of folly to try to prove that yourself because you’re actually allowed to use a calculator for the ACT. That way, you save a lot of time, and you also increase the chances of getting the answer right.

You’re allowed to use the calculator only on the math portion of the test, which includes the ACT WorkKeys Applied Math. You better get one for yourself, as students who take the test can’t share the calculators with each other.

# The ACT Calculator Policy

The ACT has a calculator policy that expressly defines what kind of calculator you’re allowed to use for the test. If you break any of these rules, you may be dismissed and your test may be voided.

Here are some of the more crucial regulations regarding your choice of calculators.

- You can’t use computers of any kind, such as laptops, tablets, and handheld computers. Even PDAs are explicitly prohibited.
- Calculators with Computer Algebra System functionality (CAS) are also not allowed. These include various advanced CAS calculators made by Texas Instruments, Hewlett-Packard, and Casio.
- It’s not legal to use electronic writing pads or pen-input devices, though you can use the Sharp EL 9600.
- You also can’t use calculators with the QWERTY letter key design. However, you can use these calculators if they’re provided in a secure test delivery platform. Also, you can use calculators with letter keys if they’re not in the QWERTY format.
- If your calculator emits sound, you have to turn off the sound.
- If your calculator has some paper tape, you have to remove the tape.
- If your calculator can hold documents, then you have to remove all the documents.
- If your calculator can hold programs and apps, then you have to take off those apps that offer CAS functionality.
- If your calculator has an infrared data port, you have to cover that port with electrician’s tape or duct tape.
- If your calculator has a power cord, you have to remove the power cord.

The most crucial rule here is the one regarding the CAS functionality. This may be allowed for the SAT, but not for the ACT.

# Best Options for your ACT Calculator

With this policy in mind, you have to make sure your chosen calculator complies with all the restrictions. Of course, that’s not the only factor.

You may want to get the calculator with all the advanced features, but then these features come at a cost. If you have a more modest calculator, then you may have to do without certain functions.

More advanced features may also make the calculator more complicated to use. Keep in mind that the ACT has time controls. You don’t want to waste time trying to figure out how to use the calculator during the test. You better be familiar with it before you use it for the ACT.

It also should be compact and lightweight. A bulky calculator can be rather annoying to hold on to. The display should be easy to read, and the keys should be arranged sensibly for easier use.

It should work reliably well. The battery power should last long enough for you to finish the test.

With these factors in mind, let’s check out our top prospects for the best calculators for the ACT.

## TI-84 Plus CE

This graphics calculator from Texas Instruments is perhaps the standard by which all the other calculators are measured. It’s the proven champion that has truly stood the test of time. It’s a true classic, like the Ford Mustang or the Rolex Submariner.

In comparison with the most modern calculators available today, it’s not exactly advanced. But it gets upgraded and updated regularly, so it’s not as if you’re using an obsolete model. Besides, the fundamental design is tried and tested, and its extremely durable.

What’s more, it’s also quite affordable. Since you can use it for both the ACT and SAT, you save a ton of money with this option if you’re taking both tests.

### Functionality

Everything you need for the ACT is all here. You get the graphing capabilities, along with the algebraic and statistical functionalities. Because of its simpler design, it’s relatively easy to use. You won’t have to spend to much time with it to become familiar with how to use it efficiently. You have plenty of shortcuts you can use that you can easily keep in mind.

This isn’t a calculator from the 1970s. It’s a modern calculator, which can even use a USB cable for data transfer. You have features like MathPrint, which lets you input and see equations and symbols exactly the way they appear in your textbooks.

Because of its popularity, you’ll also find a lot of 3^{rd}-party apps that you can download for this. These apps can then extend the capabilities of this calculator, so you’re able to get extra features such as spreadsheet functions.

### Looks

This uses a nice and clear color display with high resolution. With color coding and grid lines, you’re able to read and differentiate various graphs from each other.

The buttons are laid out nicely with ample spacing for large fingers. Its weight and thickness were reduced by 30% compared to the previous generation. It’s eminently easy to bring along.

It also uses a rechargeable battery. You can use its docking station, but when you’re on the road you can recharge it with a wall charger or a USB cable.

### Pros

- Rechargeable battery
- Nicely compact
- Readable display
- Allows for equations to appear accurately

### Cons

- Its features may not be as advanced as some other models.
- For the SAT, it lacks features that you can find in other SAT calculators

## TI-83 Plus

This is allowed for the ACT, and also for SAT, PSAT, and AP exams. That shouldn’t be surprising, since it’s a very basic model.

It’s for those who don’t have a large budget or are unwilling to spend to much for a calculator. Yet this may also appeal to you (even if you can spend more money) if you don’t want the hassle of learning to use a more complicated calculator.

### No-Nonsense Display

The display is in black and white, which should tell you that this isn’t exactly a premium calculator. Yet there are those who think of color displays as superfluous features. If you share that opinion, then this is the basic, no-nonsense display you want. It’s still big enough and clear enough for data analysis.

### Usage

This can really help not just with your ACT and other exams, but for high school and college math. In fact, some people buy this in their high school freshman year and discover that it’s good enough for high school, the ACT, and college. For those who don’t care to buy calculators regularly, this is a god-send.

It also helps that this calculator was built to last. The materials are all hard, including the impact-resistant slide case. It’s very common to use this for years without anything going wrong.

However, there’s no rechargeable battery. You’ll have to make do with 4 AAA batteries. Bring extra batteries for the ACT, just to be safe.

### Basic Features

This works nicely for pre-algebra, statistics, physics, and fundamental graphing uses. But you can use flash technology to upgrade the apps if you wish.

You can use statistical data plotting for your pictographs, scatter plots, and pie charts.

It even has built-in support for sensors for the pre-installed data collection interfaces. That means you can use the calculator to measure the temperature, sound levels, light, and voltage.

### Pros

- Extremely affordable
- Simple and very easy to use
- Truly durable
- Works for high school and college math

### Cons

- Black and white display
- No rechargeable batteries
- Relatively basic functionality
