Understanding SAT Calculator Rules
The SAT exam allows the use of most standard calculators, but there are specific guidelines set by the College Board to ensure fairness and prevent cheating. Understanding these rules is crucial to avoid any last-minute issues on test day. The SAT Math section is divided into two parts: one where calculators are permitted, and one where they are not. The calculator section allows you to use your device to solve problems, but only if it meets the College Board's criteria.
What Calculators Are Generally Allowed?
Most graphing calculators, scientific calculators, and even basic four-function calculators are permitted on the SAT, provided they do not have prohibited features. This includes popular models like the Texas Instruments TI-83, TI-84 series, Casio fx-9750GII, and many others. The key is that the calculator must be a standalone device and not a smartphone or tablet app, unless it's a very basic function calculator.
What Calculators Are NOT Allowed?
The College Board explicitly prohibits calculators that:
- Have a paper tape printer.
- Have a power cord.
- Are operated by batteries AND have a power cord.
- Make noise or have a light that cannot be turned off.
- Are cell phones, smartphones, tablets, or any other wireless communication devices.
- Are operated by a stylus or electronic pen.
- Have a QWERTY keypad (unless it's a graphing calculator that meets other criteria).
- Have Computer Algebra System (CAS) capabilities.
- Have memory that can be loaded with formulas or other information.
- Can perform symbolic algebraic manipulations.
- Can perform symbolic trigonometric manipulations.
- Can perform symbolic calculus manipulations.
Essentially, the SAT aims to test your math skills, not your ability to program a calculator or use advanced software features. If your calculator can solve equations for you symbolically or has features that give you an unfair advantage, it's likely not allowed.
The SAT Calculator Policy in Detail
The official SAT calculator policy is designed to be straightforward. You can use a calculator on the "No Calculator" section of the SAT, but it's a separate section where no calculator is permitted. For the section where calculators are allowed, the College Board states that any electronic device that can "add, subtract, multiply, and divide" is acceptable. However, they also list specific exclusions. The most common reasons a calculator might be disallowed are:
- CAS (Computer Algebra System): These are powerful features found on some advanced calculators that can solve equations symbolically.
- QWERTY Keypad: Calculators with a full keyboard layout like a computer are generally prohibited, though some graphing calculators with this feature might be allowed if they don't have other prohibited functions.
- Programmable Features: While some basic programming is okay, calculators that can store extensive formulas or perform complex symbolic manipulations are not.
- Smart Devices: Using a smartphone, tablet, or smartwatch as a calculator is strictly forbidden.
It's always best to err on the side of caution. If you're unsure about your specific calculator model, check the official College Board calculator policy or use our SAT calculator eligibility checker.
SAT Calculator Policy: Formula and Mathematical Explanation
The "formula" for SAT calculator eligibility isn't a mathematical equation in the traditional sense, but rather a set of logical rules and conditions. Our SAT Calculator Eligibility Checker uses these rules to determine if a calculator is acceptable. The core logic can be broken down as follows:
Eligibility Rules:
- Rule 1: Prohibited Features Check
- If the calculator has a CAS, it is NOT allowed.
- If the calculator has a QWERTY keypad AND it's not a graphing calculator that meets other criteria, it is NOT allowed. (Our checker simplifies this by flagging QWERTY as a potential issue).
- If the calculator has programmable keys or memory that can store formulas/advanced functions, it is NOT allowed.
- Rule 2: Device Type Check
- If the device is a smartphone, tablet, smartwatch, or any communication device, it is NOT allowed.
- Rule 3: Basic Functionality Check
- If the calculator is a basic four-function, scientific, or graphing calculator that does NOT violate Rule 1 or Rule 2, it IS generally allowed.
Simplified Logic for the Checker:
The calculator checks for disqualifying factors. If any of these are present, the calculator is deemed unacceptable:
- Disqualifier 1: CAS enabled.
- Disqualifier 2: QWERTY keypad (unless it's a specific type of graphing calculator, which we flag as potentially problematic).
- Disqualifier 3: Programmable features that allow storing formulas or advanced functions.
- Disqualifier 4: Being a smart device (phone, tablet, etc.).
If none of these disqualifiers are met, and the device is a standard scientific, graphing, or basic calculator, it is considered acceptable. The intermediate results in our calculator show which specific rules were triggered or passed.
Practical Examples (Real-World Use Cases)
Let's look at some common calculator scenarios and how they relate to the SAT policy:
Example 1: Standard Graphing Calculator
Scenario: A student wants to use their Texas Instruments TI-84 Plus. This calculator has graphing capabilities, can store programs, and has a standard numeric keypad.
- Calculator Model: TI-84 Plus
- Calculator Type: Graphing Calculator
- Programmable Keys: Yes (but generally acceptable for SAT)
- CAS: No
- QWERTY: No
- Smart Device: No
Result: Acceptable. The TI-84 Plus is a widely approved calculator for the SAT. While it has programmable features, they are not considered CAS or symbolic manipulation tools that violate the policy.
Example 2: Advanced Scientific Calculator
Scenario: A student brings a Casio fx-CG50. This is a powerful graphing calculator.
- Calculator Model: Casio fx-CG50
- Calculator Type: Graphing Calculator
- Programmable Keys: Yes
- CAS: No
- QWERTY: No
- Smart Device: No
Result: Acceptable. Similar to the TI-84 Plus, this calculator is generally permitted as it doesn't have CAS or other prohibited features.
Example 3: Calculator with CAS
Scenario: A student has a Texas Instruments TI-Nspire CX CAS.
- Calculator Model: TI-Nspire CX CAS
- Calculator Type: Graphing Calculator
- Programmable Keys: Yes
- CAS: Yes
- QWERTY: No
- Smart Device: No
Result: NOT Acceptable. The presence of the CAS feature disqualifies this calculator according to the SAT policy.
Example 4: Using a Smartphone
Scenario: A student plans to use the calculator app on their iPhone.
- Calculator Model: iPhone Calculator App
- Calculator Type: Basic Four-Function (App)
- Programmable Keys: No
- CAS: No
- QWERTY: Yes (on the phone)
- Smart Device: Yes
Result: NOT Acceptable. Smartphones and tablets are explicitly banned as calculators on the SAT.
Example 5: Calculator with QWERTY Keyboard
Scenario: A student has a calculator with a full QWERTY keyboard, like some older programmable models.
- Calculator Model: Example Programmable Model
- Calculator Type: Programmable Calculator
- Programmable Keys: Yes
- CAS: No
- QWERTY: Yes
- Smart Device: No
Result: Likely NOT Acceptable. While some graphing calculators with QWERTY might be allowed if they lack other prohibited features, a standalone calculator primarily defined by its QWERTY keypad is usually disallowed.

Key Factors That Affect SAT Calculator Results
Several factors determine whether your calculator is acceptable for the SAT. Understanding these can help you choose the right device or prepare accordingly:
- CAS Capability: This is one of the most significant disqualifiers. If your calculator can solve equations symbolically (e.g., solve 'ax + b = c' for 'x' without you plugging in numbers), it's likely not allowed.
- QWERTY Keypad: While some graphing calculators have this, it's a red flag. The SAT wants to prevent devices that function like mini-computers.
- Programmable Memory: Calculators that allow you to store complex programs or extensive lists of formulas are generally prohibited. Basic programming for simple functions is usually okay, but the line can be blurry.
- Device Type: Smartphones, tablets, smartwatches, and any device with wireless communication capabilities are strictly forbidden. The SAT aims to level the playing field, and these devices offer too many advantages.
- Power Source: Calculators that require a power cord or have both batteries and a power cord are not permitted. Only battery-operated devices are allowed.
- Noise and Lights: Any calculator that makes noise or has lights that cannot be turned off is disallowed to prevent disruptions.
Choosing a calculator that is widely recognized as SAT-approved, like many standard TI or Casio scientific and graphing models, is the safest bet. If in doubt, bring a simpler scientific calculator as a backup.
