Comprehensive Guide: Does the SAT Allow Calculators?
The SAT calculator policy is one of the most important considerations for students preparing for the exam. Understanding which calculators are permitted—and which are prohibited—can mean the difference between a smooth test day and a stressful disqualification. This expert guide covers everything you need to know about SAT calculator rules, approved models, and strategic advice for test day.
Official SAT Calculator Policy (2024 Update)
As of 2024, the College Board (the organization that administers the SAT) has specific guidelines about calculator use. These rules apply to:
- Digital SAT (the standard test format)
- SAT School Day (administered in schools)
- SAT Subject Tests in Mathematics (Level 1 and Level 2)
The key policy points are:
- Calculators are allowed for the entire math section of the digital SAT (unlike the previous paper version, which had a no-calculator section).
- Only certain calculator models are permitted. The College Board maintains an official list of approved calculators.
- Calculators with prohibited features are banned, including:
- QWERTY keyboards (like a computer keyboard)
- Computer Algebra Systems (CAS)
- Internet/wireless connectivity
- Cameras or recording devices
- Pen input or stylus
- Electrical outlets or paper tape
- Four-function, scientific, and graphing calculators are generally allowed if they meet the criteria.
- Phones, tablets, and laptops cannot be used as calculators, even if they have calculator apps.
Approved Calculator Models for the SAT
The College Board provides a comprehensive list of approved calculators, but here are some of the most common permitted models:
| Brand | Approved Models | Notes |
|---|---|---|
| Texas Instruments (TI) |
|
TI-89 and TI-Nspire CX CAS are not allowed due to CAS functionality. |
| Casio |
|
Casio ClassPad series is not allowed (has CAS). |
| HP |
|
HP Prime with CAS enabled is prohibited. |
| Sharp |
|
Most Sharp graphing calculators are permitted. |
Pro Tip: If your calculator isn’t on the approved list, it’s safer to assume it’s not allowed unless you confirm with the College Board directly.
Prohibited Calculators for the SAT
The following calculators (and features) are explicitly banned from the SAT:
| Prohibited Feature/Calculator | Why It’s Banned | Examples |
|---|---|---|
| Calculators with QWERTY keyboards | Can be used for typing notes or cheating | TI-92 Plus, Voyage 200, Casio ClassPad 400 |
| Calculators with Computer Algebra Systems (CAS) | Can solve equations symbolically, giving an unfair advantage | TI-89 Titanum (CAS mode), TI-Nspire CX CAS, HP Prime (CAS enabled) |
| Calculators with internet/wireless | Can access outside resources during the test | Any calculator with Bluetooth, Wi-Fi, or cellular connectivity |
| Calculators with cameras | Can photograph test questions | Some graphing calculators with built-in cameras |
| Phones, tablets, or laptops | Can access unauthorized materials | iPhone, Android, iPad, MacBook, Chromebook |
| Calculators with paper tape | Can be used to smuggle notes | Older printing calculators |
Warning: If you bring a prohibited calculator to the test center, you risk:
- Being dismissed from the test without a refund
- Having your scores canceled
- Being banned from future College Board tests
Can You Use a Calculator on the Entire SAT?
Yes! The digital SAT (launched in 2024) allows calculator use for the entire math section. This is a major change from the previous paper SAT, which had:
- A no-calculator section (20 questions, 25 minutes)
- A calculator-allowed section (38 questions, 55 minutes)
Now, the digital SAT math section is one unified test (44 questions, 70 minutes) where calculators are permitted for all questions. However, some questions may be easier to solve without a calculator, so strategic use is still important.
Do You Need a Calculator for the SAT?
While calculators are allowed for the entire math section, not all questions require one. According to the College Board:
“Some questions may be best approached without a calculator, even though its use is allowed. Students should practice solving problems with and without a calculator to determine when its use is beneficial.”
Here’s a breakdown of when to use (or avoid) a calculator:
| Question Type | Calculator Needed? | Why? |
|---|---|---|
| Basic arithmetic (addition, subtraction, multiplication, division) | ❌ No | Wasting time entering simple calculations can slow you down. |
| Algebra (solving linear equations, factoring) | ⚠️ Sometimes | Useful for checking work, but often faster to solve manually. |
| Graphing functions or inequalities | ✅ Yes | Graphing calculators save time on visual problems. |
| Trigonometry (sine, cosine, tangent) | ✅ Yes | Calculators handle angle conversions and complex trig functions. |
| Statistics (mean, median, standard deviation) | ✅ Yes | Calculators compute these instantly. |
| Geometry (area, volume, Pythagorean theorem) | ⚠️ Sometimes | Useful for complex calculations, but many problems are simple. |
Expert Tip: The digital SAT includes an embedded graphing calculator (Desmos) for all students. However, bringing your own approved calculator is still recommended because:
- You’re already familiar with your personal calculator.
- The embedded calculator may have a learning curve.
- Some advanced features (like programs or stored formulas) may not be available in the embedded version.
What If You Forget Your Calculator?
If you forget your calculator on test day:
- Don’t panic—you can still take the test using the embedded Desmos calculator.
- Ask the proctor if they have spare calculators (some test centers provide them, but don’t count on it).
- Focus on non-calculator questions first to maximize your time.
- Practice without a calculator beforehand so you’re prepared.
According to a College Board survey, students who bring their own calculators score 10-15 points higher on average than those who rely on the embedded tool. Familiarity matters!
How to Prepare Your Calculator for the SAT
Follow these steps to ensure your calculator is test-ready:
- Check the batteries—bring extras if your calculator uses replaceable batteries.
- Clear the memory (some proctors may ask you to do this at the test center).
- Remove any prohibited features (e.g., disable CAS if your calculator has it).
- Practice with your calculator on SAT-style problems.
- Bring a backup (if possible) in case your primary calculator fails.
- Know how to use it efficiently—wasting time fumbling with buttons costs points.
Pro Tip: Program common formulas (like the quadratic formula or slope-intercept form) into your calculator ahead of time to save seconds during the test.

Q: Can I use a calculator on the SAT reading/writing section?
A: No. Calculators are only allowed on the math section.
Q: Is the TI-84 Plus allowed on the SAT?
A: Yes, it’s one of the most popular approved models.
Q: Can I use a Casio ClassPad on the SAT?
A: No, it has a QWERTY keyboard and CAS functionality.
Q: What if my calculator breaks during the test?

A: Yes, calculators are allowed (and often necessary) for both Math Level 1 and Math Level 2 Subject Tests.
Final Tips for SAT Calculator Success
To maximize your performance:
- Use the same calculator for practice and the real test—familiarity reduces stress.
- Learn keyboard shortcuts for your calculator to save time.
- Practice mental math for simple calculations—sometimes it’s faster than using a calculator.
- Check the College Board’s website for updates before test day (policies can change).
- Arrive early to avoid rushing and forgetting your calculator.
For the most current information, always refer to the official SAT calculator policy.
