TI-84 Calculator Online — Free Graphing Calculator Emulator
No app. No download. No cost. Just open your browser and start calculating.
This is a fully functional TI-84 Plus CE graphing calculator emulator that runs entirely in your browser. Whether you’re graphing a quadratic function at midnight before an exam or working through statistical distributions during class, everything you need is right here — free, fast, and ready to use on any device.
What Is the TI-84 Plus CE Online Calculator?
The TI-84 Plus CE is one of the most widely used graphing calculators in the world, standard in high school and university math courses across the United States and beyond. Our browser-based emulator replicates its full functionality without requiring you to buy or carry the physical device.
It runs on the same underlying logic as the real calculator — so every button, every menu, and every calculation behaves exactly the way you’d expect. If you’ve used a TI-84 before, you already know how to use this.
Key Features
Full Graphing Capability
Graph standard functions, parametric equations, polar graphs, and sequences — all at the same time if needed. Use the built-in zoom, trace, and table features to analyze behavior, find intercepts, and explore asymptotes visually.
Statistical Tools Built In
Run regressions, compute descriptive statistics, build histograms, and work with box plots without ever leaving the page. The stats menu is fully intact, covering everything from one-variable analysis to chi-square tests.
Advanced Mathematical Functions
- Trigonometric functions including sin, cos, tan, and their inverses
- Logarithmic and natural exponential functions
- Matrix operations (supports up to 10×10 matrices)
- Complex number arithmetic
- Equation solving and numerical calculus tools
- List operations and sequence evaluation
TI-BASIC Programming Support
The programming environment is included. Students learning to code with TI-BASIC can write, edit, and run programs directly in the emulator — no extra setup required.
Zoom Controls for Any Screen
Use the + and − zoom controls above the calculator to scale it up or down based on your screen size. Whether you’re on a large desktop monitor or a smaller tablet, you can adjust the view to whatever feels comfortable.
Works on Every Device
Desktop, laptop, tablet, or phone — this calculator loads and runs on all of them. No installation, no account, no permissions. Just open the page and use it.
Who This Calculator Is For
Students — Stop borrowing calculators or stressing about leaving yours at home. Access the full TI-84 Plus CE from any device, any time. It’s especially useful during online homework sessions, distance learning, or late-night study runs.
Teachers and Instructors — Project a live, working TI-84 on your classroom screen or interactive whiteboard. Demonstrate graphing techniques, walk through statistical problems, or show step-by-step function analysis without needing a physical calculator or expensive software.
Parents — If your child uses a TI-84 at school, this gives you the same interface at home so you can actually help them without guessing what buttons do what.
Engineers and Technical Professionals — Need quick access to matrix math, complex number calculations, or a reliable graphing tool during a work session? This is faster to open than any installed application.

How to Get Started
- Click any button on the calculator using your mouse or tap it on a touchscreen
- Adjust the size using the zoom controls at the top if the display feels too small or large
- Navigate menus exactly as you would on a physical TI-84 — the button layout is identical
- Graph functions by pressing the
Y=button, entering your expression, and hittingGRAPH - Access statistics through the
STATmenu, just like the real device

Frequently Asked Questions
Is this TI-84 emulator completely free? Yes. There are no hidden fees, no subscription, and no account required. Open the page and start using it immediately.
Does this work for standardized tests like the SAT or ACT? This online emulator is built on the same functionality as the physical TI-84 Plus CE. For practice and homework, it is a perfect substitute. For the actual test day, you will need to bring a physical calculator as devices must meet specific exam rules.
Can I use this on my phone? Absolutely. The emulator loads and functions on mobile browsers. Use the zoom controls to scale the calculator to a comfortable size for your screen.
Is the TI-84 Plus CE good for calculus? Yes. It handles numerical derivatives and definite integrals, graphs functions with precision, and supports the kinds of visual analysis that make calculus concepts much easier to understand.
Does it support graphing multiple functions at once? It does. You can enter multiple equations in the Y= screen and graph them simultaneously — useful for comparing functions, finding intersections, or visualizing systems of equations.
What is TI-BASIC and can I use it here? TI-BASIC is the built-in programming language for Texas Instruments calculators. It lets you write custom programs for calculations, games, or automation. The full programming environment is available in this emulator through the PRGM menu.
Do I need to install anything? Nothing. The entire calculator runs in your browser using JavaScript. No plugins, no apps, no downloads.
The TI-84 Plus CE remains the gold standard for graphing calculators in education — and now there’s no reason to be without one. Bookmark this page and you’ll always have a reliable, fully featured graphing calculator within reach.
