Complete Guide: Can I Use My Calculator on the SAT?

Key Takeaways

• The SAT has strict calculator policies that change periodically
• Only certain calculator models are permitted during the Math section
• Calculators are only allowed for part of the Math test (not the entire section)
• Using a prohibited calculator can result in score cancellation
• The College Board provides an official list of approved calculators

Official SAT Calculator Policy (2024 Update)

The College Board, which administers the SAT, has specific rules about calculator use during the test. These rules are designed to maintain test security and fairness while allowing students to use appropriate tools for mathematical calculations.

As of the 2024 testing year, here are the fundamental rules:

1. Calculator use is only permitted during the Math Test — Calculator portion (38 questions, 55 minutes)
2. No calculators are allowed during the Math Test — No Calculator portion (20 questions, 25 minutes)
3. You must bring your own calculator – none are provided at the test center
4. Calculators cannot be shared with other test-takers
5. Test center staff will inspect your calculator before the test begins

Approved Calculator Types for the SAT

The College Board divides approved calculators into four main categories:

Calculator Type	Examples	SAT Approval Status	Notes
Graphing Calculators	TI-84 Plus, TI-Nspire (non-CAS), Casio FX-9750GII	✅ Approved	Most popular choice for SAT takers
Scientific Calculators	TI-30XS, Casio FX-115ES PLUS, HP 35s	✅ Approved	Good alternative to graphing calculators
Four-Function Calculators	Basic calculators (addition, subtraction, etc.)	✅ Approved	Not recommended due to limited functionality
Calculators with Computer Algebra Systems (CAS)	TI-89, TI-Nspire CAS, HP Prime	❌ Prohibited	Can perform symbolic math (solve equations)

Prohibited Calculator Features

The College Board explicitly bans calculators with certain features that could provide unfair advantages or compromise test security:

• QWERTY keyboards (like a computer keyboard)
• Internet access or cellular/wireless connectivity
• Camera, audio, or video recording capabilities
• Computer Algebra Systems (CAS) that can solve equations symbolically
• Paper tape (calculators that print)
• Makes noise (beeping, talking, etc.)
• Requires electrical outlet (must be battery or solar powered)
• Has a stylus (unless it’s a basic touchscreen scientific calculator)

Recommended Calculators for the SAT

Based on functionality, reliability, and compliance with SAT policies, these are the top recommended calculators:

Rank	Calculator Model	Type	Pros	Cons	Price Range
1	Texas Instruments TI-84 Plus CE	Graphing	Most popular, reliable, good battery life	Expensive, steep learning curve	$100-$150
2	Casio FX-9750GII	Graphing	More affordable, color screen	Less intuitive interface	$50-$80
3	Texas Instruments TI-30XS MultiView	Scientific	Approved for all tests, affordable	Limited graphing capabilities	$15-$25
4	Hewlett Packard HP 35s	Scientific	RPN input, durable	Unconventional interface	$50-$70
5	Texas Instruments TI-Nspire (non-CAS)	Graphing	Advanced features, color screen	Expensive, complex	$120-$160

SAT Calculator Policy: Common Questions Answered

Can I use my phone as a calculator on the SAT?

No. Phones are strictly prohibited during the test, even if you’re just using the calculator app. Test center staff will collect all phones before the test begins.

What if my calculator runs out of batteries during the test?

You should bring extra batteries just in case. However, you cannot share calculators with other test-takers. If your calculator dies and you don’t have replacements, you’ll have to complete the calculator portion without one.

Can I use a calculator with a touchscreen?

Yes, as long as it doesn’t have prohibited features like QWERTY keyboards or CAS capabilities. Many modern scientific and graphing calculators have touchscreens and are SAT-approved.

What if my calculator is on the prohibited list but I didn’t know?

Ignorance isn’t an excuse. If you bring a prohibited calculator, you won’t be allowed to use it, and in some cases, it might be considered a violation that could affect your scores. Always check the official College Board policy before test day.

Can I use a calculator during the entire Math section?

No. The Math section is divided into two parts:

1. No Calculator portion (20 questions, 25 minutes)
2. Calculator portion (38 questions, 55 minutes)

You’ll need to put your calculator away during the first part.

How to Prepare Your Calculator for SAT Day

Follow this checklist to ensure your calculator is ready and compliant:

1. Verify it’s on the approved list – Check the College Board’s official calculator policy
2. Test all functions – Make sure it’s working properly before test day
3. Replace batteries – Even if they seem fine, put in fresh batteries
4. Clear memory – Remove any stored formulas or programs (some test centers may require this)
5. Remove the cover – Some calculators must be removed from their cases during inspection
6. Practice with it – Be comfortable with your calculator’s functions before test day
7. Bring a backup – If possible, have a simple scientific calculator as a backup

What Happens If You Violate Calculator Policies?

The College Board takes calculator violations seriously. Potential consequences include:

• Confiscation of the calculator – You’ll have to complete the test without it
• Incident report filed – Could lead to score cancellation
• Dismissal from the test center – In severe cases (like using a phone)
• Scores withheld or canceled – If the violation is discovered after testing
• Future test restrictions – May affect your ability to take future College Board tests

According to the official SAT test day policies, “Using prohibited aids (including prohibited calculators) may result in your dismissal from the test center, cancellation of your scores, or both.”

Alternative Strategies If You Can’t Use Your Preferred Calculator

If your calculator isn’t approved or you can’t bring one, consider these alternatives:

1. Borrow an approved calculator – Ask friends or teachers if you can borrow one for test day
2. Purchase an affordable scientific calculator – The TI-30XS is under $20 and fully approved
3. Practice mental math – Many questions can be solved without a calculator
4. Use the test booklet for scratch work – Write out calculations step by step
5. Memorize key formulas – Know the quadratic formula, slope formula, etc.
6. Consider a graphing calculator rental – Some schools and test prep companies offer rentals

Expert Tips for Using Your Calculator Effectively on the SAT

Having an approved calculator is just the first step. To maximize its effectiveness:

• Know when NOT to use it – About 30-40% of Math questions don’t require a calculator
• Practice with the same model – Get comfortable with its specific functions
• Clear memory before the test – Some centers require this during check-in
• Use it for complex calculations – Save time on multi-step problems
• Check your work – Use it to verify answers you calculated mentally
• Be efficient – Don’t waste time on calculator-dependent questions
• Know the shortcuts – Learn how to quickly access common functions

Recent Changes to SAT Calculator Policies

The SAT has undergone several changes in recent years, including updates to calculator policies:

• 2016 – Redesigned SAT introduced, with calculator use restricted to specific sections
• 2020 – Temporary policy changes due to COVID-19 (some test centers allowed calculator use throughout)
• 2021 – Digital SAT announced, with built-in calculator for the calculator section
• 2023 – Updated list of approved calculators published, with some older models removed
• 2024 – Stricter enforcement of calculator inspections at test centers

For the most current information, always check the official SAT Suite website before your test date.

Digital SAT and Calculator Use

Starting in 2024, the SAT is transitioning to a digital format. This brings some changes to calculator policies:

• Built-in calculator – The digital testing app includes a calculator for the calculator section
• Still can bring your own – Physical calculators are still allowed (and often preferred)
• Calculator section remains – The test structure with calculator/no-calculator sections continues
• Approved models unchanged – The list of approved physical calculators remains the same
• Practice with digital tools – The College Board offers practice with the built-in calculator

The digital SAT’s built-in calculator is a Desmos graphing calculator, which is a powerful tool that students should familiarize themselves with before test day.
