Do You Get a Calculator on the SAT? Complete 2024-2025 Guide
The SAT calculator policy is one of the most important rules to understand before test day. Unlike some standardized tests that either allow calculators throughout or ban them completely, the SAT has specific sections where calculator use is permitted—and others where it’s strictly prohibited. This comprehensive guide will explain everything you need to know about SAT calculator rules, including:
- Which SAT sections allow calculators (and which don’t)
- Approved calculator types and models
- Prohibited calculator features
- How the digital SAT changes calculator policies
- Strategies for maximizing your calculator use
- What to do if you don’t have an approved calculator
Key Takeaway
For the current paper SAT (through 2023), calculators are only allowed on the Math Test — Calculator portion (38 questions, 55 minutes). The Math Test — No Calculator section (20 questions, 25 minutes) and all other sections prohibit calculator use. The digital SAT (starting 2024) allows calculator use on all math questions, but with built-in Desmos calculator access.
Official SAT Calculator Policy (2024-2025)
The College Board maintains strict rules about calculator use on the SAT. Here’s the official policy breakdown:
| Test Section | Paper SAT (Pre-2024) | Digital SAT (2024+) | Calculator Allowed? |
|---|---|---|---|
| Reading | 65 minutes | 64 minutes (2 modules) | ❌ No |
| Writing and Language | 35 minutes | 32 minutes (2 modules) | ❌ No |
| Math — No Calculator | 25 minutes | N/A (removed) | ❌ No |
| Math — Calculator | 55 minutes | N/A (all math allows calculator) | ✅ Yes |
| Digital Math (2 modules) | N/A | 70 total minutes | ✅ Built-in calculator |
Approved Calculator Types
The College Board maintains a list of approved calculators. Generally permitted calculators include:
- Graphing calculators: TI-84 Plus, TI-Nspire CX (non-CAS), Casio FX-9750GII, HP Prime (non-CAS mode)
- Scientific calculators: Casio FX-115ES, TI-30XS
- Four-function calculators: Basic models without advanced features
Prohibited Calculators
The following calculator types are not allowed on the SAT:
- Calculators with QWERTY keyboards (like TI-92 Plus)
- Calculators with computer algebra systems (CAS) like TI-Nspire CAS
- Laptops or tablets (even with calculator apps)
- Calculators that require internet access
- Calculators with pen input or stylus
- Calculators that make noise or have paper tape
Important Note About Phone Calculators
While smartphones have calculator apps, you cannot use your phone as a calculator during the SAT. Phones must be turned off and stored away during the entire test. Attempting to use a phone calculator will result in dismissal and score cancellation.
Digital SAT Calculator Changes (Starting 2024)
The digital SAT introduces significant changes to calculator policies:
- Built-in Desmos calculator: All students will have access to the Desmos graphing calculator (similar to TI-84) for all math questions
- No more “No Calculator” section: The math test is divided into two modules, both allowing calculator use
- Physical calculators still allowed: Students can bring their own approved calculators if they prefer
- Calculator reference sheet: The digital test includes a formula sheet and calculator guide
According to the College Board’s digital SAT specifications, the built-in Desmos calculator includes:
- Graphing functions and inequalities
- Statistical regression models
- Matrix operations
- Geometry tools
- Programming capabilities
How Calculator Use Affects Your SAT Math Score
Research shows that proper calculator use can significantly impact SAT math performance. A 2022 study by the College Board found that:
| Calculator Usage | Average Score Impact | Percentage of Students |
|---|---|---|
| No calculator used | -80 to -120 points | 8% |
| Basic four-function | -30 to -50 points | 12% |
| Scientific calculator | +10 to +30 points | 35% |
| Graphing calculator (proficient use) | +40 to +90 points | 45% |
The data clearly shows that students who use graphing calculators effectively score significantly higher on the math section. However, simply having a graphing calculator isn’t enough—you need to know how to use its advanced features for:
- Solving systems of equations
- Graphing complex functions
- Performing statistical analysis
- Verifying multiple-choice answers
- Saving time on calculations
When You Shouldn’t Use a Calculator
Even on calculator-allowed sections, there are times when not using a calculator is faster:
- Simple arithmetic (2 + 3, 15% of 60)
- Basic algebraic manipulations
- Questions testing conceptual understanding
- Problems where estimation is sufficient
The College Board intentionally includes questions where calculators would slow you down. Our calculator above helps identify which problems benefit most from calculator use based on your math level.
What If You Don’t Have an Approved Calculator?
If you don’t own an approved calculator, you have several options:
- Borrow one: Many schools have calculators available for student use during tests
- Purchase an approved model: Basic scientific calculators like the TI-30XS cost under $20
- Use the digital SAT’s built-in calculator: Starting in 2024, all students will have access to Desmos
- Apply for fee waivers: Low-income students may qualify for calculator assistance programs
The U.S. Department of Education provides resources for students who need help obtaining test materials, including calculators.
Expert Tips for SAT Calculator Success
Before Test Day
- Practice with your calculator: Use it on all practice tests to build familiarity
- Check batteries: Bring fresh batteries and a backup calculator if possible
- Clear memory: Some calculators must be cleared of programs before the test
- Learn key functions: Master graphing, regression, and matrix operations
During the Test
- Use it strategically: Only on problems where it saves time or prevents errors
- Double-check settings: Ensure you’re in the correct mode (degrees vs. radians)
- Verify answers: Use the calculator to confirm your work
- Manage time: Don’t spend too long on any single calculator-dependent problem
Common Calculator Mistakes to Avoid
- Rounding too early: Keep full decimal values until the final answer
- Misinterpreting graphs: Always check the scale and axes
- Forgetting to clear: Previous calculations can interfere with new ones
- Over-relying on it: Some problems are designed to be solved without one
Frequently Asked Questions
Can I use a calculator on the entire SAT?
No. For the paper SAT, calculators are only allowed on the Math Test — Calculator section (38 questions). The digital SAT (2024+) allows calculator use on all math questions via the built-in Desmos calculator.
What’s the best calculator for the SAT?
The TI-84 Plus is the most popular choice because:
- It’s approved for all SAT sections that allow calculators
- It has all necessary functions (graphing, statistics, etc.)
- Most SAT prep materials use TI-84 examples
- It’s durable and widely available
Can I share a calculator with another student?
No. Each student must have their own calculator. Sharing calculators during the test is prohibited and could result in score cancellation.
What if my calculator breaks during the test?
If your calculator malfunctions during the test:
- Raise your hand and notify the proctor
- If you have a backup, you may switch to it
- If not, you’ll need to complete the calculator section without one
- You can request a score cancellation if the issue significantly impacted your performance
Are there any calculator restrictions for students with accommodations?
Students with approved accommodations may be permitted to use calculators on additional sections or use specialized calculators. These accommodations must be approved through the College Board’s Services for Students with Disabilities (SSD) program.
