What Is the TI 84 Calculator?
The TI 84 is made by Texas Instruments and has been the go-to graphing calculator for students across the US for decades. You’ll find it in high school math classrooms, on standardized test desks, and in college lecture halls. It handles everything from basic arithmetic to calculus, statistics, matrix operations, and even basic programming.
The TI-84 Plus CE is the latest version it’s the one with the color screen and the rechargeable battery. That’s exactly what this site runs: a full TI-84 Plus CE online emulator, powered by the official HTML5 engine from Texas Instruments itself.
Why Use a TI-84 Calculator Online?
The honest answer? Because the physical one is expensive and inconvenient. A brand new TI-84 Plus CE will run you around $100 at most stores. Used TI 84 calculators are cheaper, but availability varies and you never quite know what condition you’re getting. The online TI-84 calculator here gives you the exact same functionality zero cost, zero setup.

How to Use the Online TI 84 Calculator
Using the online version feels just like picking up the physical device. Here’s how to get started:
- Basic Navigation: Click or tap any button on the calculator face to press it. Your mouse works exactly like your finger on the real device. On mobile, tap away — the touchscreen response is smooth.
- Adjusting the Size: Use the + and − zoom controls at the top of the page to make the calculator bigger or smaller. Whatever size you set gets saved automatically.
- Accessing Secondary Functions (2nd Key): Press the blue 2nd button to unlock secondary functions printed in blue above each key — same as on the physical TI-84 Plus CE.
- Switching Between Degrees and Radians: Hit MODE and navigate to the angle setting. Switch between Degree and Radian depending on what your problem calls for.
- Graphing a Function: Press Y= to open the equation editor. Type in your function, then press GRAPH. Use ZOOM to adjust the viewing window, and TRACE to move along the curve.
Full Feature List Nothing Stripped Out
This isn’t a dumbed-down version. Every feature on the physical TI-84 Plus CE is available here.

- Finding derivatives numerically — Use nDeriv( from the MATH menu
- Definite integrals — Use fnInt( or the ∫f(x)dx option in the CALC menu while graphing
- Normal distribution problems — Found under 2nd → DISTR → normalcdf( and invNorm(
- Linear regression — Enter data in L1 and L2, then run LinReg from the STAT → CALC menu
- Combinations and permutations — MATH → PRB → nCr and nPr
- Converting degrees to radians — Multiply by π/180, or change the MODE setting
TI-84 Calculator Price and Alternatives
The TI-84 Plus CE currently retails for around $100 new. A used TI-84 calculator can be found for $40–$60 depending on condition. If you’re looking for a TI-84 calculator for sale nearby, check your school’s library or student Facebook groups — many students sell theirs after AP exams.

Frequently Asked Questions
Is this actually a real TI-84 Plus CE calculator?
Yes. This runs the official TI-84 Plus CE HTML5 emulator from Texas Instruments, loaded through the TestNav platform. The calculation engine is identical to the physical device not an approximation or recreation.
Can I use this to study for the SAT or ACT?
Absolutely. The TI-84 Plus CE is one of the most commonly used calculators on both exams. Practicing on this online version means you learn the exact menus and button layout before test day. Just remember that the actual in-person exam requires a physical calculator.
Does it work offline?
You need an internet connection for the first load while the emulator files are downloaded to your browser. After that initial load, the calculator can continue running locally even if you lose connection mid-session.
Will my work be saved when I close the tab?
No. Like the physical TI-84, this resets when you close or refresh the page. Your zoom setting is saved, but any data, programs, or equations you entered will be gone. Write down your work or take a screenshot before closing.
What’s the difference between TI-84 Plus and TI-84 Plus CE?
The TI-84 Plus CE is the newer model with a full-color backlit screen and a rechargeable battery instead of AAAs. This emulator runs the CE version, which is the current standard in most schools and on standardized tests.
How do I change the batteries on my physical TI-84?
The TI-84 Plus runs on four AAA batteries. Remove the battery cover on the back, swap them out, and you’re good. The TI-84 Plus CE uses a rechargeable lithium battery and comes with a USB charger similar to charging a phone.
Where can I buy a TI-84 calculator nearby?
