Can You Use a Calculator on the SAT?
An interactive tool and guide to the official SAT calculator policy.
SAT Calculator Policy Checker
Select the section of the SAT you are taking to instantly see if a calculator is permitted. For the Math with Calculator section, the Digital SAT includes an on-screen graphing calculator (Desmos), but you can also bring your own approved device.
What is the SAT Calculator Policy?
The SAT calculator policy dictates whether students can use a calculator on the SAT exam and specifies which types of calculators are allowed. This policy is designed to ensure fairness and prevent any student from having an unfair advantage. The question of “can you use a calculator on the sat” depends entirely on which section of the test you are on. For the Digital SAT, a powerful graphing calculator (Desmos) is built directly into the testing application for the Math section, but students are still permitted to bring their own approved calculator.
This policy primarily affects the two Math sections of the SAT. One section explicitly forbids the use of any calculator, while the other permits it. Calculators are strictly prohibited during the Reading and Writing and Language sections. Understanding these rules is critical for test day success.
Common Misconceptions
- “Any calculator is fine.” – False. There is a specific list of unapproved calculators and features (e.g., those with Computer Algebra Systems or CAS, QWERTY keyboards, or internet access).
- “You need the most expensive calculator.” – False. While a graphing calculator is helpful, all questions on the calculator section can be solved without one. A familiar scientific calculator is often sufficient.
- “The built-in calculator is enough.” – For many, yes. The integrated Desmos calculator is very powerful. However, if you are more comfortable and faster with your own handheld calculator, it’s highly recommended you bring it.
The SAT Calculator “Formula”: A Logic-Based Explanation
The “formula” for determining if you can you use a calculator on the sat is a set of logical rules, not a mathematical equation. It’s a simple decision tree based on the test section and the type of calculator.
Step-by-Step Policy Derivation:
- Identify the Test Section: Is it Math, Reading, or Writing?
- If Reading or Writing: The result is always NO. Calculators must be put away.
- If Math: Identify the specific Math section.
- If it’s the “No-Calculator” section, the result is NO.
- If it’s the “Calculator” section, the result is YES, proceeding to the next step.
- Check Calculator Type: If the section allows a calculator, your device must be on the approved list. It cannot have prohibited features. The College Board explicitly bans calculators with Computer Algebra System (CAS) functionality.
Variables Table
| Variable | Meaning | Possible Values | Impact on Decision |
|---|---|---|---|
| Test Section | The specific portion of the SAT being administered. | Math (Calc), Math (No-Calc), Reading, Writing | The primary factor. Determines if calculators are even an option. |
| Calculator Type | The kind of calculator you have. | Graphing, Scientific, Four-Function | Most graphing and all scientific/four-function are allowed. |
| CAS Feature | Computer Algebra System (solves algebra symbolically). | Yes / No | If ‘Yes’, the calculator is BANNED, even in the calculator section. |
| Prohibited Features | Other banned features like Wi-Fi or a QWERTY keyboard. | Present / Absent | If any are present, the calculator is BANNED. |
SAT Math Sections by Calculator Usage
The SAT Math test is divided into two parts, totaling 58 questions. A significant portion of the test allows a calculator, highlighting the importance of understanding the SAT calculator policy.
Practical Examples
Example 1: Student with a TI-84 Plus
- Situation: Maria is in the second Math section (the “Calculator” section). She brought her TI-84 Plus, a very common graphing calculator.
- Analysis: The TI-84 Plus is on the College Board’s approved list and does not have a banned CAS feature. Since she is in the correct section, she is clear to use her device.
- Outcome: Maria can confidently use her TI-84 Plus to solve problems, potentially saving significant time on complex calculations. This is a clear case where knowing the answer to “can you use a calculator on the sat” is beneficial.
Example 2: Student with a TI-Nspire CX II CAS
- Situation: David is about to start the “Calculator” section. His calculator is a TI-Nspire CX II CAS.
- Analysis: Although David is in the calculator-permitted section, his calculator model has “CAS” in its name. The SAT calculator policy explicitly prohibits calculators with Computer Algebra Systems.
- Outcome: David’s calculator is not allowed. The proctor will require him to put it away. He will have to rely solely on the built-in Desmos calculator provided in the testing software. This highlights the importance of checking your specific model against the SAT calculator policy before test day.
How to Use This SAT Calculator Policy Checker
- Select Section: Choose your current SAT section from the dropdown menu.
- View Instant Result: The large colored box will immediately tell you if a calculator is permitted (“YES”) or not permitted (“NO”).
- Read the Details: The text below the main result provides important context, explaining the specific rule being applied.
- Reset If Needed: Click the “Reset” button to return the calculator to its default state.
Use this tool before your test to familiarize yourself with the rules. The primary takeaway is simple: calculator for one math section, no calculator for the other math section or for Reading/Writing. Your main responsibility is ensuring the calculator you bring is an approved model.
Key Factors That Affect the SAT Calculator Policy
Several factors determine whether you can you use a calculator on the sat. Understanding them is key to avoiding issues on test day.
| Permitted Calculators | Prohibited Devices & Features |
|---|---|
| Most Graphing Calculators (e.g., TI-84, TI-Nspire CX non-CAS) | Laptops, tablets, mobile phones, smartwatches |
| All Scientific Calculators (e.g., TI-30X) | Calculators with a QWERTY-style keyboard |
| All Four-Function Calculators (not recommended) | Calculators that require an electrical outlet |
| The built-in Desmos calculator on the Digital SAT | Calculators that make noise or can print |
| Devices with internet or wireless communication | |
| Any calculator with a Computer Algebra System (CAS) |
Detailed Factors:
- Test Section: As covered extensively, this is the number one rule. No calculators on the Reading, Writing, or the first Math section.
- Computer Algebra System (CAS): This is the most significant feature-based ban. A CAS can solve algebraic equations symbolically, which the College Board deems an unfair advantage.
- QWERTY Keyboard: Any device with a typewriter-style keyboard is prohibited.
- Connectivity: Calculators with internet, Bluetooth, cellular, or any wireless communication capability are strictly forbidden.
- Power Source: The calculator must be battery-powered. Devices that need to be plugged into an electrical outlet are not allowed.
- External Devices: You cannot connect your calculator to any other device, including printers or other calculators.
Frequently Asked Questions (FAQ)
Yes, but only on the designated “Math Test – Calculator” section. You cannot use it on the “Math Test – No Calculator,” Reading, or Writing sections. For the Digital SAT, there’s also an embedded calculator available.
For the Digital SAT, you are not at a total disadvantage. A powerful on-screen graphing calculator (Desmos) is built into the testing software for the entire Math section. You can use this instead.
Yes. While graphing calculators have more features, a scientific calculator is sufficient to solve all problems. No question requires a graphing calculator specifically. In fact, being very familiar with a simpler scientific calculator can be faster than navigating a complex graphing one.
Check the model name—it often includes “CAS” (e.g., TI-Nspire CX II CAS). You can also test it: try to have it solve an equation like “2x + 1 = 5” and see if it gives you “x = 2”. If it can manipulate variables, it likely has a CAS and is banned.
No. Sharing calculators is strictly prohibited and could lead to both of your scores being canceled.
While not always checked, it’s a good practice. The rules state you must remove any programs or documents. Starting with a clean slate prevents any potential issues with proctors.
Yes, you are allowed to bring a backup calculator. It must also be an approved model and should be kept under your desk. You need to get permission from the proctor before switching to it.
Yes, the calculator policy for the PSAT/NMSQT and other tests in the SAT Suite is the same as the SAT policy, including the ban on CAS calculators.
