SAT Calculator Policy Checker: Are You Allowed to Use a Calculator on the SAT?

SAT Calculator Policy Checker

A smart tool to determine if you are allowed to use a calculator on the SAT based on official rules.

Which SAT Math Section Are You Taking?

Check any features your calculator has:

Has a QWERTY (computer-style) keyboard.
Has a Computer Algebra System (CAS).
Has wireless, Bluetooth, or cellular capability.
Needs an electrical outlet to function (not battery-operated).
Makes noise or prints on paper.
Uses a stylus or pen (e.g., touchscreen input).
Is part of a phone, tablet, or laptop.

Select your test section and calculator features to see the result.

What is the “are you allowed to use a calculator on the sat” Policy?

The question of whether you are allowed to use a calculator on the SAT is a critical one for test-takers. The College Board, which administers the SAT, has a detailed policy to ensure fairness. The SAT Math test is split into two parts: a “Math – No Calculator” section and a “Math with Calculator” section. As the names imply, calculator use is strictly forbidden on the first part but permitted on the second. For the Digital SAT, a calculator is available for the entire math section. However, even on the calculator-permitted section, not all calculators are allowed. The policy is designed to prevent unfair advantages from devices with advanced functionalities like computer algebra systems (CAS) or communication features.

Anyone preparing for the SAT must understand these rules. Using a non-compliant calculator can lead to dismissal from the test and cancellation of your scores. This calculator helps you quickly determine if your device meets the specific criteria set by the College Board.

SAT Calculator Rules and Explanation

The “formula” for determining if a calculator is allowed is a set of logical rules based on its features. The primary factor is the test section, followed by a checklist of prohibited functionalities. Your calculator’s eligibility is determined by passing all the checks for the section you are in.

Variables for Calculator Eligibility

This table outlines the key factors (variables) our calculator uses to determine if you are allowed to use a calculator on the SAT.
Variable / Feature	Meaning	Status if Present	Typical Range
Test Section	The part of the SAT Math test being taken.	Determines if any calculator is allowed.	Math with Calculator / Math – No Calculator
QWERTY Keyboard	A computer-style keyboard.	Not Allowed	Present / Absent
Computer Algebra System (CAS)	Functionality that can solve algebraic equations symbolically.	Not Allowed	Present / Absent
Wireless Capability	Features like Wi-Fi, Bluetooth, or cellular data.	Not Allowed	Present / Absent
External Power	The need for an electrical outlet to operate.	Not Allowed (Must be battery-powered)	Required / Not Required
Phone/Tablet/Laptop	Using a general-purpose device instead of a dedicated calculator.	Not Allowed	Is a device / Is not a device

Practical Examples

Example 1: A Standard Graphing Calculator

A student has a Texas Instruments TI-84 Plus CE for the Math with Calculator section. This is a common and widely accepted model.

Inputs: Section = Math with Calculator, No prohibited features checked.
Result: ALLOWED
Reasoning: The TI-84 Plus CE does not have a QWERTY keyboard, a CAS, wireless capabilities, or any other prohibited feature, and it is being used in the correct section.

Example 2: A Calculator with a Prohibited Feature

A student attempts to use a calculator with a built-in QWERTY keyboard during the Math with Calculator section.

Inputs: Section = Math with Calculator, “Has a QWERTY keyboard” is checked.
Result: NOT ALLOWED
Reasoning: Calculators with computer-style keyboards are explicitly banned by the College Board because they are considered computer-like devices.

How to Use This “Are You Allowed to Use a Calculator on the SAT” Calculator

Using this tool is a simple, three-step process to ensure you’re ready for test day:

Select the Test Section: Choose between the “Math with Calculator” and “Math – No Calculator” sections from the dropdown menu. This is the first and most important step.
Indicate Calculator Features: Read through the list of prohibited features. Check the box next to any feature that your specific calculator model possesses.
Review Your Result: The calculator will instantly update, showing whether your device is “ALLOWED” or “NOT ALLOWED”. An explanation will detail the specific rule that led to the decision.

If your calculator is not allowed, the explanation will help you understand why, so you can find an approved device before your test. For more details, you can always check out the official SAT Calculator Policy.

Key Factors That Affect Calculator Eligibility

Several key factors determine if you are allowed to use a calculator on the SAT. Understanding them is crucial for compliance.

1. Test Section: The most basic rule. No calculators of any kind are permitted on the “No Calculator” section.
2. Computer Algebra System (CAS): A major recent change in policy prohibits calculators with CAS, which can manipulate algebraic expressions symbolically.
3. QWERTY Keyboard: Any calculator with a typewriter-style keyboard is banned.
4. Wireless Communication: Devices with internet, Bluetooth, cellular, or any other wireless capability are strictly prohibited to prevent cheating.
5. Power Source: The calculator must be battery-operated. Models that require an external power source are not allowed.
6. Device Type: You cannot use the calculator function on a smartphone, tablet, smartwatch, or laptop. You must use a separate, approved handheld device. For further reading on this, see our article on SAT Test Day Checklist.

Frequently Asked Questions (FAQ)

Can I use a calculator on the digital SAT?: Yes, for the entire math portion of the digital SAT, you are allowed to use either the built-in Desmos graphing calculator or your own approved handheld calculator.
Is my TI-84 Plus calculator allowed?: Yes, the entire TI-84 series (including Plus, C Silver Edition, CE) is approved for the SAT as it does not contain a prohibited CAS.
What happens if I bring a prohibited calculator?: If you are caught using a prohibited calculator, the test proctor will likely confiscate it, and you may be dismissed from the testing center and have your scores canceled.
Can I use my phone’s calculator?: No. Phones, smartwatches, and any other general-purpose electronic devices are strictly forbidden for use as a calculator.
Are scientific calculators allowed?: Yes, all standard scientific calculators are allowed on the SAT. You can find a list of best scientific calculators for the SAT on our blog.
What about calculators with a Computer Algebra System (CAS)?: As of recent policy updates, calculators with CAS functionality are no longer permitted on the SAT. This is a significant change, so check your model carefully.
Do I have to clear my calculator’s memory?: The College Board requires that you remove any stored programs or documents from your calculator before the test. For more information, check our Guide to SAT Rules.
Can I share my calculator with another student?: No, sharing calculators is not permitted during the exam. Each student must have their own approved device.
