Can You Use a Calculator on the SATs?

An expert guide and interactive tool to check if your calculator is permitted on the SAT.

SAT Calculator Policy Checker

Enter your calculator’s model and check its features against the College Board’s rules to see if it’s likely allowed.

What is the SAT Calculator Policy?

The ability to use a calculator on the SAT depends on the section of the test and the type of calculator. For the Digital SAT, a graphing calculator is built into the testing app (Bluebook™) for the entire Math section. You are also permitted to bring your own acceptable calculator. For the paper-based SAT, there is a “Math Test – Calculator” portion where you can use an approved calculator, and a “Math Test – No Calculator” portion where you cannot. The College Board maintains a strict policy to ensure fairness.

Permitted vs. Prohibited Calculators

The core rule is that most graphing calculators, scientific calculators, and four-function calculators are allowed as long as they are not on the prohibited list. The main restrictions involve advanced functionality and communication capabilities.

Calculator Feature Admissibility

Feature Type	Status	Explanation
Graphing Capability	Permitted	Most graphing calculators (like the TI-84 series) are allowed.
Scientific Functions	Permitted	All standard scientific calculators are acceptable.
Computer Algebra System (CAS)	Prohibited	Calculators that can simplify algebraic expressions are not allowed (e.g., TI-Nspire CAS, TI-89).
QWERTY Keyboard	Prohibited	Calculators with typewriter-style keyboards are banned.
Internet/Bluetooth	Prohibited	Any device that can communicate wirelessly is not allowed.
Phones, Tablets, Laptops	Prohibited	You cannot use a general-purpose computer or phone as your calculator.
Requires Power Cord	Prohibited	Calculators must be battery-operated.

How to Use This SAT Calculator Policy Checker

Our tool is designed to simplify the process of checking your calculator against the College Board’s rules. Follow these steps:

1. Enter Model Name: Type the model of your calculator into the input field. The tool checks for specific models that are explicitly banned.
2. Select Features: Check the boxes for any features your calculator has. This is the most important step.
3. Check Status: Click the “Check Status” button to see the result.
4. Review Explanation: The tool will tell you if your calculator is likely permitted or prohibited and provide a brief explanation for the result.

Key Factors That Affect Calculator Eligibility

• Computer Algebra System (CAS): This is a major disqualifier. A CAS can perform symbolic manipulation (like factoring x²-4 into (x-2)(x+2)), which gives an unfair advantage. Models with “CAS” in their name are prohibited.
• QWERTY Keypad: Calculators with a full keyboard are not allowed as they can be used to store text notes.
• Communication: Any form of wireless communication (internet, Bluetooth, infrared) is strictly forbidden to prevent cheating.
• Power Source: Calculators must be battery-powered. You cannot use a device that needs to be plugged into an outlet.
• Hardware Type: You cannot use a smartphone, tablet, or laptop in place of a handheld calculator.
• Specific Model Bans: The College Board explicitly prohibits certain models, such as the TI-89, TI-92, and HP Prime. Our Digital SAT Guide has more details on this.

Frequently Asked Questions (FAQ)

1. What happens if I bring a prohibited calculator?

The test proctor will not allow you to use it. You may have to take the math section without a calculator, or you could be dismissed from the test.

2. Can I use the calculator on the entire digital SAT?

Yes, for the digital SAT, a calculator is available for the entire math section through the testing app, and you can also use your own approved handheld calculator.

3. Is the TI-Nspire allowed?

The standard TI-Nspire CX is allowed, but the TI-Nspire CAS is NOT allowed because it has a Computer Algebra System.

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

While not always enforced, the policy states you should remove any stored documents. It’s a good practice to clear RAM before the test.

5. Are all scientific calculators allowed?

Yes, all standard scientific calculators are permitted.

6. Can I use my phone as a calculator?

No. Phones, smartwatches, and any other wearable technology are strictly prohibited.

7. What if my calculator model isn’t on any list?

If it doesn’t have any prohibited features (like CAS, a QWERTY keyboard, or internet), it is most likely allowed. Use our checker above to be sure. Check out our resources on SAT Math Practice for more tips.

8. Is a graphing calculator necessary?

No question on the SAT requires a graphing calculator, but it can be a very helpful tool for solving problems more quickly. The built-in Desmos calculator on the digital SAT is also very powerful.
