Can You Use a Calculator on the SAT? Complete 2024 Guide
The SAT calculator policy is one of the most important rules to understand before test day. Unlike some standardized tests that allow calculators on all math sections, the SAT has specific restrictions about when and what type of calculator you can use. This comprehensive guide will explain everything you need to know about SAT calculator rules, approved models, and strategies for both calculator and no-calculator sections.
Official SAT Calculator Policy (2024 Update)
The College Board, which administers the SAT, has clear guidelines about calculator usage:
- Math Test – Calculator Section: You may use an approved calculator on this portion of the exam
- Math Test – No Calculator Section: No calculators are permitted for these questions
- Reading and Writing Sections: Calculators are never allowed
- Essay (if taken): Calculators are not permitted
The calculator section contains 38 questions to be completed in 55 minutes, while the no-calculator section has 20 questions with a 25-minute time limit.
Approved Calculator Types for the SAT
Not all calculators are permitted on the SAT. The College Board maintains an official list of approved calculators, but here are the general categories of acceptable devices:
| Calculator Type | Allowed? | Notes |
|---|---|---|
| Graphing calculators | ✅ Yes | Most models allowed, but some with QWERTY keyboards are prohibited |
| Scientific calculators | ✅ Yes | All standard scientific calculators are permitted |
| Four-function calculators | ✅ Yes | Basic calculators are allowed but not recommended |
| Calculators with raised displays (for visually impaired) | ✅ Yes | Allowed with prior approval for accommodations |
| Laptops or tablets | ❌ No | Even if just for calculator functions |
| Phones or smartwatches | ❌ No | All electronic devices must be turned off |
| Calculators with internet access | ❌ No | Any connectivity features disqualify the device |

Prohibited Calculator Features
The College Board explicitly bans calculators with these features:
- Wi-Fi, Bluetooth, or any wireless communication
- Audio recording or playback capabilities
- Camera or other photographic equipment
- Pen input or stylus writing
- Electrical outlets or cords (must be battery-powered)
- Paper tape output
- Makes noise or “talks”
- Requires an internet connection
If you bring a prohibited calculator, you’ll be required to put it away and won’t be able to use any calculator for the calculator-permitted section.
Recommended Calculators for the SAT
Based on student feedback and expert recommendations, these are some of the best calculators for the SAT:
- Texas Instruments TI-84 Plus CE: The most popular graphing calculator among SAT takers, with excellent graphing capabilities and programmability
- Texas Instruments TI-Nspire CX II: Allowed for the SAT (without the CAS version), with advanced features for calculus
- Casio fx-9750GII: A more affordable graphing calculator option that meets all SAT requirements
- Hewlett-Packard HP Prime: Approved for the SAT with powerful graphing and computation features
- Texas Instruments TI-30XS: A scientific calculator that’s sufficient for most SAT math problems
For most students, a graphing calculator like the TI-84 Plus CE offers the best balance of functionality and ease of use for the SAT math sections.
Strategies for the Calculator Section
Even though you can use a calculator on this portion of the test, you should still approach it strategically:
- Don’t rely too much on your calculator: About 30% of questions in the calculator section can be solved more quickly without one
- Use it for complex calculations: Save time on problems with multiple steps or large numbers
- Graph functions when helpful: For questions about intersections or maximum/minimum points
- Check your work: Use the calculator to verify answers you’ve already solved
- Practice with your calculator: Become proficient with all the functions you might need
Strategies for the No-Calculator Section
The no-calculator section tests your mathematical fluency and number sense. Here’s how to prepare:
- Memorize key formulas: Area, volume, slope, quadratic formula, etc.
- Practice mental math: Work on calculating percentages and fractions quickly
- Learn to factor: Many problems can be solved by factoring rather than using the quadratic formula
- Estimate when possible: Look for answer choices that are clearly too large or too small
- Work backwards: Plug in answer choices to see which one fits
- Skip and return: Don’t waste time on difficult problems early in the section
Common Calculator Mistakes to Avoid
Many students make these calculator-related errors on the SAT:
- Using a calculator when it’s not allowed: Double-check which section you’re in
- Bringing a prohibited calculator: Verify your model is on the approved list
- Forgetting to bring a calculator: You won’t be able to borrow one during the test
- Not knowing how to use your calculator: Practice with it before test day
- Relying too much on the calculator: Some problems are designed to be solved without one
- Not clearing memory: Some calculators store programs that might be prohibited
- Bringing a calculator with dead batteries: Bring fresh batteries just in case
SAT Calculator Policy for Students with Accommodations
Students who receive testing accommodations through the College Board may have different calculator rules:
- Extended time: Doesn’t change calculator policies
- Calculator for all math sections: Some students are approved to use calculators on both math sections
- Specialized calculators: May be approved for students with visual impairments or other needs
- Separate testing room: Calculator policies still apply unless specifically modified
If you receive accommodations, your approval letter will specify any modifications to the standard calculator policy. Always verify with the College Board if you’re unsure about what’s permitted.
How to Prepare for Both Calculator and No-Calculator Sections
Effective SAT math preparation should include practice for both types of sections:
| Preparation Activity | Calculator Section | No-Calculator Section |
|---|---|---|
| Practice problems | Focus on complex calculations and graphing | Emphasize mental math and algebraic manipulation |
| Timed drills | Work on efficiency with calculator use | Build speed in mental calculations |
| Formula memorization | Important but calculator can help | Critical for success |
| Error analysis | Check for calculator input mistakes | Review algebraic and arithmetic errors |
| Test simulations | Practice switching between calculator and no-calculator mindsets | Same as left |
Aim to spend about 60% of your math preparation time on the no-calculator section, as this is where students typically struggle more due to the need for stronger fundamental skills.
Digital SAT Calculator Policy (Starting 2024)
With the transition to a digital SAT format, there are some important changes to the calculator policy:
- Built-in calculator: The digital testing app includes a graphing calculator for the calculator-permitted section
- Bring your own: You can still bring an approved physical calculator if you prefer
- No calculator section remains: Some math questions still prohibit calculator use
- Calculator tool features: The digital calculator includes graphing, regression, and other advanced functions
The digital calculator is a Desmos graphing calculator, which many students find more powerful than basic physical calculators. However, if you’re more comfortable with your own approved calculator, you can still bring it to the test center.
Frequently Asked Questions About SAT Calculators
Can I use my phone as a calculator on the SAT?
No, all phones and electronic devices must be turned off and put away during the entire test, including breaks.
What if my calculator breaks during the test?
The test center won’t provide a replacement. You’ll have to complete the calculator section without one, which is why it’s important to practice both with and without a calculator.
Can I share a calculator with another student?
No, you cannot share calculators or any other materials during the test.
Do I need a graphing calculator for the SAT?
While not required, a graphing calculator can be helpful for certain problems. However, all questions can be solved without one.
Can I use a calculator on the PSAT?
The PSAT has the same calculator policy as the SAT – permitted on one math section and prohibited on the other.
What if I forget my calculator?
You’ll have to complete the calculator section without one. Some test centers might have extras, but you shouldn’t count on this.
Can I use a calculator with a touchscreen?
Yes, as long as it doesn’t have any prohibited features like internet access or a QWERTY keyboard.
Final Tips for SAT Calculator Success
- Check your calculator: Verify it’s on the approved list at least a month before test day
