Can You Use a Calculator on the SAT?

An interactive tool and guide to the official College Board calculator policy.

SAT Calculator Policy Checker

Answer the following questions about your calculator to determine if it’s likely allowed on the SAT. This checker reflects the latest rules.

What “Can You Use a Calculator on the SAT” Really Means

The question isn’t simply “can you use a calculator on the SAT,” but rather which calculator you can use and when. For the modern Digital SAT, the policy is straightforward: an approved calculator is allowed on the entire Math section. This is a change from the old paper-based test, which had a “No-Calculator” portion. Furthermore, the digital test includes a powerful built-in graphing calculator (Desmos), so you are guaranteed to have access to a great tool. However, you are still permitted to bring your own handheld calculator, and understanding the rules is crucial to avoid issues on test day.

The Official Digital SAT Calculator Policy Explained

The College Board sets clear guidelines to ensure fairness. The most significant recent update is the ban on calculators with a Computer Algebra System (CAS) for tests beginning in August 2025. A CAS can perform symbolic algebra, like solving equations with variables, which is now considered an unfair advantage.

All students taking the Digital SAT have access to the Desmos graphing calculator embedded directly in the Bluebook™ testing app. You can also bring your own acceptable device. The key is knowing what makes a calculator “acceptable.”

SAT Section	Calculator Allowed?
Reading and Writing	No
Math (All Modules)	Yes (Built-in Desmos or approved handheld)

How to Use This SAT Calculator Policy Checker

Using the tool above is simple and can prevent a major headache on test day. Follow these steps:

1. Read each question in the checker carefully.
2. If your calculator has the feature described, check the box next to it. Be honest—the goal is to know the rules before you go.
3. Once you have answered all the questions, click the “Check My Calculator” button.
4. The tool will instantly provide a result: “PERMITTED” or “PROHIBITED,” along with an explanation of which rule applies.
5. If you want to start over, simply click the “Reset” button.

Practical Examples of Allowed vs. Prohibited Calculators

Example 1: The TI-84 Plus (Permitted)

A student wants to bring their TI-84 Plus. Using the checker, they confirm it doesn’t have a QWERTY keyboard, wireless access, or a CAS. The result is PERMITTED. This is a standard and widely accepted graphing calculator for the SAT.

Example 2: A Smartphone (Prohibited)

Another student thinks about using their smartphone’s calculator app. The moment they check the first box—”Is it a laptop, tablet, smartphone, or smartwatch?”—the tool flags it as PROHIBITED. Such devices are never allowed in the testing room.

Key Factors That Affect Calculator Eligibility

Understanding these factors is essential for anyone asking “can u use a calculator on the sat”. Failure to comply can result in you not being able to use your calculator.

• No QWERTY Keyboards: Any calculator with a keyboard like a computer’s is banned.
• No Wireless Communication: Devices with Wi-Fi, Bluetooth, or cellular data are strictly forbidden.
• No Power Cords: Your calculator must be battery-powered. You cannot plug it into an outlet during the exam.
• No Banned Features: Devices that can make noise, print, or have a camera are not allowed.
• No Phones or Smart Devices: No smartphones, smartwatches, or tablets are permitted as calculators.
• No Computer Algebra System (CAS): Effective August 2025, calculators with CAS are prohibited. If your calculator model includes “CAS” in its name (like the TI-Nspire CX II CAS), it will not be allowed.

Frequently Asked Questions (FAQ)

1. Can I use my phone’s calculator on the SAT?

No. All smartphones, smartwatches, tablets, and laptops are strictly prohibited from use as calculators.

2. Is a graphing calculator required for the SAT?

No, it’s not required. All questions can be solved without one, and the Digital SAT provides a built-in Desmos graphing calculator. However, many students find a familiar graphing calculator like the best calculator for SAT to be faster.

3. What happens if I bring a prohibited calculator?

The test proctor will not allow you to use it. You will have to take the Math section either without a handheld calculator or by using the built-in one on the testing platform.

4. Can I use the built-in Desmos calculator on the Digital SAT?

Yes. The Desmos graphing calculator is available for the entire Math section for all students taking the Digital SAT. You can even practice with it before the test. This is an important part of your digital SAT practice test routine.

5. Are four-function calculators allowed?

Yes, all four-function and scientific calculators are allowed, provided they don’t have any prohibited features.

6. Is the TI-Nspire CAS allowed on the SAT?

No. As of August 2025, calculators with CAS (Computer Algebra System) functionality, including the TI-Nspire CAS models, are prohibited. The non-CAS version (TI-Nspire CX) is still allowed.

7. Do I need to clear my calculator’s memory?

While not always enforced, it is a recommended practice to clear your calculator’s memory before the test. Test centers reserve the right to check.

8. What’s on the SAT test day checklist?

Besides your approved calculator, you’ll need your admission ticket, a valid photo ID, and a couple of No. 2 pencils. Make sure your calculator has fresh batteries!
