Calculators play a major role in speeding up your calculations and getting an accurate answer to the problem. To ace the ACT, you need to have a calculator that suits your needs and follows the guidelines of the ACT. Using a calculator not permitted by the ACT will get you dismissed from the test, and you will receive no scores.

Isn’t that scary, after you have studied day and night for the test? Getting a proper calculator for the ACT is, therefore, very crucial. So don’t worry; we got you covered.

In the following article, I have mentioned all the required details a candidate must know about the ACT calculators, which are not permitted, and our top recommendations that are suitable for the students.

**ACT Calculator Policy**

The ACT has permitted calculators, including any 4-function, graphing, and scientific calculators, but are excluded from the banned calculator list.

The main aim of ACT is to minimize disturbances and prevent any candidate from taking undue advantage during the test. However, they also want to ensure that the students use the calculators they are familiar with and comfortable with.

The next section comprises intermediate algebra and coordinates geometry with a weightage of 30% in the Math portion. The section consists of 18 questions. The last section comprises trigonometry and geometry with 18 questions. The section sums up to 30% of the maths portion.

You will require the calculator in the second and third sections. In the first section, you can perform calculations using your basic knowledge. Using a calculator in the first field will reduce your speed in the first section.

You can make the most of the calculator while finding the area and circumference and working on the basic function.

**Tips to remember while buying a calculator for the ACT**

The best calculator you should carry for the ACT is the one approved by ACT guidelines that you are familiar with. Before attempting the test, you must be well-equipped and familiar with the calculator you have decided to use for the ACT. Hence, you must make a point to practice well the use and hacks of the calculator.

Next, before buying the calculator, look at the calculator recommended for the ACT and compare them according to your needs. Then, you can check out which calculator fits your budget and function requirements. Finally, you can avoid unnecessarily going for the expensive ones if the budget-friendly calculator meets your needs.

If you already own a calculator, here are a few tips to modify your calculators to make them acceptable for the ACT:

- You must turn off any sound that the calculator emits.
- Remove the paper tape from the calculator if there is any.
- Any power cord attached to the calculator must be removed and detached.
- If you own a calculator with an infrared port like HP 38G, 39G, or 48G series, you need to cover up the infrared port with transparent duct tape.
