Complete Guide: Are You Allowed a Calculator on the SAT?
The SAT calculator policy is one of the most important rules to understand before test day. Using an unapproved calculator can result in score cancellation, while bringing the right calculator can significantly improve your math performance. This comprehensive guide covers everything you need to know about SAT calculator rules, approved models, and strategies for calculator use.
Official SAT Calculator Policy (2024 Update)
The College Board maintains strict guidelines about calculator use on the SAT. Here are the key rules:
- Calculator is only allowed on the Math Calculator portion – The SAT Math section is divided into two parts: No Calculator (20 questions) and Calculator (38 questions)
- No calculators are allowed during the No Calculator section – Using one will result in score cancellation for that section
- Only certain calculator models are permitted – The College Board publishes an official list of approved calculators
- Calculators cannot have prohibited features – This includes QWERTY keyboards, internet access, or computer algebra systems (CAS)
- You’re responsible for bringing your own calculator – Test centers won’t provide calculators

What Happens If You Bring a Prohibited Calculator?
The consequences of bringing an unapproved calculator to the SAT can be severe:
- Confiscation – Test proctors will collect prohibited calculators before the test begins
- Score cancellation – If you’re caught using an unapproved calculator during the test, your math score may be canceled
- Report to colleges – Score cancellations due to policy violations are reported to institutions you send scores to
- No refund – You won’t receive a refund for your test fee if your score is canceled
Pro Tip: Bring a Backup Calculator
The College Board recommends bringing a backup calculator in case your primary one malfunctions. Make sure both calculators are on the approved list. Also bring fresh batteries – you won’t be allowed to change batteries during the test.
How to Prepare with Your Calculator
Simply having an approved calculator isn’t enough – you need to know how to use it effectively:
- Practice with your calculator daily – The more comfortable you are, the faster you’ll work on test day
- Learn the shortcuts – Memorize key functions like graphing equations, calculating intersections, and using the catalog
- Master the equation solver – This can save significant time on algebra problems
- Practice with past SAT problems – Use official College Board practice tests with your calculator
- Know when NOT to use it – Some problems are faster to solve without a calculator
Frequently Asked Questions About SAT Calculators
Q: Can I use my phone as a calculator?
A: Absolutely not. Phones are prohibited during the entire test, including as calculators.
Q: What if my calculator breaks during the test?
A: You can use your backup calculator if you brought one. If not, you’ll have to complete the section without one.
Q: Are solar-powered calculators allowed?
A: Yes, as long as they don’t have prohibited features and are on the approved list.
Q: Can I share a calculator with another test-taker?
A: No, you must bring your own calculator and cannot share during the test.
Q: What about calculators with color displays?
A: Color displays are allowed as long as the calculator model is approved (like the TI-84 Plus CE).
Alternative Calculator Strategies
If you don’t have access to an approved graphing calculator, consider these alternatives:
- Use a scientific calculator – While not as powerful, scientific calculators can handle most SAT math problems
- Borrow from your school – Many schools have calculators available for student use
- Check local libraries – Some libraries lend calculators
- Use online calculators for practice – Websites like Desmos offer free graphing calculators for practice (but can’t be used on test day)
