How to use the TI-84 Plus calculator online
Start the online TI-84 Plus graphing calculator, enter your task and open a guide only when you need the exact key sequence.
Enter your task
Use familiar on-screen keys for calculations, graphs, tables and statistics.
Open help only when needed
Follow a workflow or full guide when a key sequence is unclear.
Calculator and programming tools
More than a TI-84 graphing calculator online
Move from graphing practice to independent browser tools that write, check, run and export TI-BASIC programs for TI-84 Plus CE and Evo.
Browser editor
TI-BASIC Studio
Write one program, check both calculator families and create tokenized calculator files—not renamed text documents.
.8xpfor TI-84 Plus/CE.8xp2for TI-84 Evo- Import and inspect existing programs
Independent interpreter
Program Runner
Run supported source in a protected browser worker, pause execution and inspect what the program is doing.
- Step through lines
- Breakpoints and variables
- CE and Evo compatibility modes
Compatibility workflow
Prepare an older program for Evo
Import a CE .8xp, read its source, check compatibility and prepare an Evo-format file when conversion succeeds.
- Line-level checks
- Compatibility report
- Smart CE-to-Evo conversion
Good practice: a passed browser check is useful evidence, not a guarantee of every hardware or OS behavior. Test downloaded files on the intended physical calculator.

Questions before you start
Frequently asked questions
Short, honest answers about access, compatibility and appropriate use. For any related support, please email us at support@ti84calc.org.
Is this TI-84 Plus calculator online free?
Yes. The calculator, learning guides, TI-BASIC Studio and Program Runner can be used with no download required and without creating an account.
Who is this Online TI-84 Calculator intended for?
This online TI-84 calculator is intended for students and teachers with limited resources, people who study or work remotely, and anyone who urgently needs browser-based access to a familiar graphing calculator for learning, homework, lesson preparation or demonstrations.
Does this page use the official TI-84 Plus CE HTML5 emulator from Texas Instruments?
Yes. The embedded calculator runtime, state and faceplate load from Pearson TestNav's Texas Instruments resources.
Does the online TI-84 graphing calculator work on phones and Chromebooks?
It is designed for current desktop and mobile browsers. Screen size, browser restrictions and the external runtime can affect the experience.
Is this online calculator identical to a physical TI-84 Plus CE?
No. It supports many familiar TI-84 workflows, but an online implementation can differ from physical calculator hardware and operating systems.
Can I create calculator-ready TI-BASIC program files?
Yes. TI-BASIC Studio can create tokenized .8xp files for TI-84 Plus/CE and .8xp2 files for TI-84 Evo. Test downloaded files on the intended physical model.
Can I use this website during the SAT, ACT or AP exam?
Do not assume a third-party website is permitted. Follow current testing-provider and school rules and use only calculator tools allowed for the assessment.
Why does this TI-84 Plus online calculator need internet access?
The calculator runtime is delivered from TestNav, so the calculator normally requires an internet connection. The learning pages and independent programming tools are separate parts of this website.
