What Types of Calculators Are Used for the SAT?
For the SAT®, students are allowed to use a calculator only on the Math section. The SAT calculator policy clearly defines which devices are acceptable to ensure a fair testing experience for everyone. While many standard and graphing models are approved, not every calculator is allowed on test day. Understanding the types of approved SAT calculators ahead of time helps you avoid surprises and focus fully on solving problems. Choosing a calculator that matches SAT rules and your comfort level can also improve efficiency during the exam.
Acceptable/Approved SAT Calculators
On the SAT, students may use handheld calculators that meet the SAT calculator policy guidelines. Approved SAT calculators include basic four-function models, scientific calculators, and certain graphing models that do not have CAS functionality. Make sure your calculator does not include prohibited features such as symbolic algebra systems, wireless or internet connectivity, cameras, or QWERTY keyboards.
| Calculator Type | Examples of Approved Models |
|---|---|
| Four-function calculators | Basic 4-function handheld models with add, subtract, multiply, divide (brand varies) |
| Scientific calculators | Most standard scientific models (for example TI-30 series, Casio fx-991 series) |
| Graphing calculators: Texas Instruments | TI-73, TI-80, TI-81, TI-82, TI-83, TI-83 Plus, TI-84 Plus, TI-84 Plus CE, TI-84 Plus CE Python, TI-84 Plus Silver, TI-84 Plus C Silver, TI-84 Plus T |
| Graphing calculators: Casio | FX-6000 series, FX-6200 series, FX-6300 series, FX-6500 series, FX-7000 series, FX-7300 series, FX-7400 series |
| Graphing calculators: Sharp | EL-5200, EL-9200 series, EL-9600 series, EL-9900 series |
| Graphing calculators: Radio Shack & Other | EC-4033, EC-4034, EC-4037, NumWorks, Datexx DS-883 |
Note: This table includes categories of common acceptable calculators. The policy does not maintain a complete published list of every permitted model. If you are unsure about a specific calculator, consult College Board test day staff or the official calculator policy before test day.
Prohibited Calculators on the SAT
The College Board does not allow certain calculators on test day because their features can give students an unfair advantage or violate testing rules. Any calculator that includes prohibited capabilities must not be used during the SAT.
| Type of Prohibited Calculator | Examples or Features |
|---|---|
| Calculators with CAS functionality | TI-89, TI-92 series, TI-Nspire CAS, HP Prime, HP 48GII, Casio ClassPad 300/330/400, ClassPad II, fx-CG500 CAS models |
| Devices with symbolic algebra programs | Any calculator that can manipulate algebraic expressions symbolically |
| Calculators with QWERTY keyboards | Models that resemble computer keyboards in layout |
| Devices with connectivity features | Calculators with wireless, Bluetooth, or cellular capabilities |
| Calculators with cameras or audio/video recording | Any calculator with built-in imaging or recording hardware |
| Non-handheld or powered devices | Laptops, tablets, smartphones, smartwatches, writing pads, or calculators that require power cords |
| Other disallowed hardware | Calculators with paper tape or other nonstandard input/output methods |
Quick Reference: Handheld Calculator Tips & Rules
Using a handheld calculator effectively can save time and reduce errors on the SAT Math section. The following tips and rules summarize what you need to know to ensure your calculator is fully compliant and ready for test day.
General Tips
- Use the calculator you are most comfortable with, either your own approved handheld model or the Desmos calculator in Bluebook™.
- You can toggle between scientific and graphing modes within the Math section.
- Calculators are optional, but bringing a familiar, approved model is recommended.
- Always ensure your calculator is non-CAS.
Rules During the Test
- Do not share calculators.
- Remove programs with algebra functionality and any stored documents.
- Calculators cannot be used during the Reading and Writing sections.
- Keep calculator covers under your desk.
- Turn off all sound and cover any infrared ports.
- Only battery-powered calculators are allowed; no cords.
- Large or raised displays may require special seating at the discretion of the test coordinator.

UPDATE: The CAS Calculator Ban (Effective Aug. 2025!)
Beginning with the August 2025 SAT administrations, calculators with built-in CAS functionality are no longer permitted under the SAT test calculator policy. CAS, or computer algebra systems, allow symbolic algebra such as factoring expressions or solving equations symbolically, which is now considered an unfair advantage. Any calculator that includes CAS features is classified as a prohibited device and cannot be used on test day. Students must bring a non-CAS handheld calculator or use the embedded Desmos calculator available in the digital SAT.
How Can You Check If Your Calculator Is Non-CAS?
Start by checking the full model name of your calculator. If the word “CAS” appears anywhere in the model title, it is not a calculator approved for SAT use. You should also test whether your calculator can perform symbolic algebra, such as returning exact algebraic solutions instead of numerical ones. If you are still unsure, review the manufacturer’s specifications or compare your model against the list of approved SAT calculators to confirm it meets College Board calculator policy requirements.

Why You Should Practice With Both the Built-In and Handheld Calculator?
Using calculators effectively on the SAT can make a significant difference in your performance. Since students now have the option of a built-in digital SAT calculator or bringing a handheld calculator approved for SAT use, it is important to practice with both. Each type has unique strengths, and familiarizing yourself with both tools can help you work efficiently under timed conditions.
| Practicing With the Built-In Calculator | Practicing With a Handheld Calculator |
|---|---|
| The built-in digital SAT calculator comes with graphing tools, tables, and interactive features that are fully aligned with SAT calculator policy. Practicing with it helps you become comfortable navigating its layout, using sliders, and interpreting visual data. Because it is always available and fully approved, relying on this calculator reduces the risk of technical issues or policy violations on test day. | Handheld calculators approved for SAT use give you the advantage of familiarity, especially if you have trained with a specific model extensively. They can speed up calculations, graphing, and equation solving, making them ideal for students who prefer tactile input and personal shortcuts. Practicing with a handheld calculator ensures that you are confident using it efficiently, so you can maximize accuracy and speed when it matters most. |
Relying on only one type of calculator is not a good idea for SAT preparation. While both the built-in and handheld calculators are fully approved and useful, each offers different advantages depending on the type of problem and your personal comfort. Practicing with both ensures you are flexible, confident, and able to choose the most efficient tool on test day, helping you maximize speed, accuracy, and overall performance.
Which SAT Sections Allow Calculator Use?
On the current SAT, calculators can now be used throughout the entire Math section. However, not every question requires a calculator, and many problems can be solved using mental math or simple reasoning. Students may use an approved handheld calculator or the built-in digital SAT calculator, toggling between scientific and graphing modes as needed. Being strategic about when to use a calculator can save time and improve accuracy.

Why Choosing It Matters
Picking the right calculator can affect both your speed and accuracy on the SAT. A model you know well helps you avoid mistakes, work more efficiently, and reduce test‑day stress. Choosing a calculator that fits your skill level and the types of questions you expect on test day also allows you to focus more on problem-solving and less on figuring out how to use the device.
Features to Look for
When evaluating acceptable calculators for SAT use, focus on clarity of the display, ease of entering expressions, and access to functions you will use often, like graphing, tables, and scientific operations. Battery life and a familiar button layout also make a difference under timed conditions. Make sure the calculator does not include CAS features and complies with all SAT calculator policy rules.
