Our Mission
The TI-84 Plus CE is the most popular graphing calculator in the world. Nearly every math class in the United States — from Algebra 1 all the way to AP Calculus and Statistics — requires one. But the physical calculator costs $100–$130. Not every family can afford that.
We built TI-84 Calculator Online so that budget is never a barrier. Whether you're a 6th grader just learning about graphing, a high schooler cramming for finals, a college student finishing a statistics problem set, or a teacher building lesson plans — our calculator is here for you, right in your browser.
No signup. No download. No credit card. Just open the page and start solving.
We are especially proud that our calculator is used in over 150 countries, including places where buying a physical TI-84 is simply not an option. Education should never have a price barrier.
What Makes Us Different
A Real Emulator, Not a Copycat
Many "online calculators" just mimic the look of a TI-84. Ours is a true browser-based emulator. It runs the actual TI-84 Plus CE OS. That means every key, every function, every menu — it works exactly the same way the real calculator does. No shortcuts. No fake buttons.
Designed for Special Needs Students
We deeply care about accessibility. Our color theme switcher lets students choose a faceplate color that works for them. The touch-friendly design means students with motor challenges can use it comfortably on a tablet. We designed the layout so screen readers can navigate the page easily, and zoom controls let visually impaired students scale the calculator to a comfortable size.
Works Offline
We built this as a Progressive Web App (PWA). Students can install it on their home screen and use it completely offline — no Wi-Fi needed. This is especially important for students who don't have reliable internet access at home.
No Ads Where It Matters
We do not show ads on the calculator itself. We keep it clean and distraction-free so you can focus on your math.
Our Team
We're a small, passionate team of developers and educators who care deeply about math education. We work hard to make sure this tool stays fast, accurate, and completely free.
