Can I Use the TI-84 on the SAT?

Official SAT Calculator Policy (2025)

I have been helping students prepare for the SAT for over a decade. The number one question I get — every single year — is about calculators. "Can I bring my TI-84?" Let me give you the straight answer.

College Board, the organization that makes the SAT, has a very clear calculator policy. You can use an approved calculator on the SAT Math section. The test does not have a "no-calculator" section anymore as of March 2024 (when the paper SAT switched to the new format). That means you can use your calculator for all math questions.

College Board approves calculators that are designed for math — not for internet browsing or communication. Your TI-84 fits that description perfectly. It does math, graphs equations, and handles statistics. There are no wireless capabilities. That is exactly what College Board wants to see.

The SAT Math section has 44 questions across two modules. You have 35 minutes for each module. Having a reliable calculator you already know how to use can save you valuable minutes on test day.

Which TI-84 Models Are Approved for the SAT?

Not just one version of the TI-84 is approved — almost all of them are. Here is a full breakdown:

What You Cannot Do on the SAT With Your Calculator

The TI-84 is approved — but there are still rules. The SAT is very specific about how you use your calculator. Breaking these rules can get you disqualified. Here is what you need to know:

Battery Rule — Very Important!

Your TI-84 Plus CE uses a rechargeable battery — just like a phone. The SAT testing room will not let you plug it in to charge. If your calculator runs out of battery mid-test, you are stuck. Always charge it the night before your exam until it is at 100%.

Old TI-84 Plus models use AAA batteries. If you have one of those, bring a fresh pack of batteries and switch them out the evening before test day.

TI-84 vs Other SAT Calculators — Which Is Best?

I have seen students walk into the SAT with everything from a $10 dollar-store calculator to a TI-Nspire CX II. Here is my honest take after watching thousands of students take this test:

My recommendation? Stick with the TI-84 Plus CE. Here is why:

• It is the most commonly taught calculator in American high schools. The chances are you already know how to use it.
• Graphing on the SAT saves time. You can solve certain algebra and geometry problems visually instead of doing long algebra by hand.
• The TI-84 has a statistics menu that calculates mean, standard deviation, and regression with just a few button presses.
• The color screen makes reading graphs easy and fast — no squinting at low-resolution pixels.

7 TI-84 Tips to Boost Your SAT Math Score

Owning a TI-84 is one thing. Knowing how to use it fast during a timed test is another. Here are 7 tips I give every student I work with before the SAT:

• 1

  Graph equations to find answers instantly

  If you see an equation problem, graph it. Press [Y=], type the equation, hit [GRAPH], then use [2nd] + [CALC] to find intersections or zeros. This is often faster than solving by hand — and you get the exact answer.

• 2

  Use the TABLE feature to check values

  After graphing, press [2nd] + [GRAPH] to open the TABLE. It shows you a list of exact (x, y) values for your equation. This is perfect for checking if a specific value satisfies an equation — no algebra required.

• 3

  Store numbers in variables to avoid re-typing

  If a problem gives you a value like π = 3.14159 or a long number, store it. Type the number, then press [STO→] and a letter key (like X). Now type X in your calculations. No more typos on long numbers.

• 4

  Use STAT for mean, median, and standard deviation

  The SAT loves statistics questions. Press [STAT], go to EDIT, and enter your data in L1. Then press [STAT], go to CALC, and select 1-Var Stats. It calculates mean (x̄), standard deviation (Sx), and min/max instantly — saving you minutes of hand arithmetic.

• 5

  Fix a blank graph with ZoomFit

  Did you graph something and see a blank screen? Do not panic. Press [ZOOM] and select option 0 (ZoomFit). The calculator automatically adjusts the window to show your graph. This saves at least 30 seconds of fumbling with window settings.

• 6

  Use the fraction template for cleaner answers

  Press [ALPHA] + [Y=] to open the fraction template. This lets you type fractions exactly as they look in the problem — so you reduce the chance of order-of-operations errors when entering something like (3+5)/(2-1).

• 7

  Practice with our free TI-84 online before test day

  Muscle memory matters. The more you use your calculator, the faster you will be on test day. If you do not have a physical TI-84, use our free online TI-84 Plus CE emulator every day this week. It is identical to the real thing.

What About the Digital SAT?

Starting in 2024, the SAT is now offered in a digital format through Bluebook, College Board's official testing app. This is different from the paper SAT. Here is what you need to know about calculators and the Digital SAT:

• Built-in Desmos calculator: The digital SAT has a free calculator built directly into the software. It is a Desmos graphing calculator — the same engine that powers our free Graphing Calculator page.
• Bring your own calculator too: College Board still allows you to bring an approved physical calculator (like your TI-84) to the digital SAT. Many students prefer it because it is faster for certain calculations.
• Online TI-84 simulators are NOT allowed: You cannot open a website or use an internet-based calculator on a test device. The Bluebook app locks your screen.
