Free TI-84 Plus CE Graphing Calculator Online
A fully working TI-84 Plus CE graphing calculator running right in your browser. No account, no install, no cost — open the page and start calculating.
TI-84 Plus CE Calculator — Use It Free, Right Here
This is the TI-84 Plus CE HTML5 emulator from Texas Instruments, running directly in your browser through the TestNav platform. We put it on a clean page so you can get to it fast — whether you are on a Chromebook at school, a MacBook at home, or an iPhone on the bus.
The physical calculator costs around $100. For most students who need it a few times a week for homework or test prep, that is a lot. This gives you the same experience at zero cost.
How to Use the TI-84 Online Calculator
Using this online TI-84 is nearly identical to the physical device. Here is how to get started:
- Click or tap buttons on the calculator just like pressing physical keys. Mouse and touchscreen both work fine.
- Adjust the size with the + and − buttons above the calculator until it fits your screen.
- Press 2nd to access secondary functions shown in blue above each key — same as the real device.
- Press MODE to switch between degree and radian, adjust number format, and change other settings.
- Press Y= to enter equations for graphing, then hit GRAPH to plot them.
Your zoom level is saved automatically — the page remembers your setting next time.
Full TI-84 Plus CE Features — Nothing Removed
This is not a simplified version. Every function the physical calculator has is here:
📈 Graphing Functions
Plot standard functions, parametric equations, polar graphs, and sequences. Zoom, trace, and find intersections on the graph screen.
📊 Statistics & Regression
One- and two-variable stats, linear and exponential regression, histograms, box plots, and scatter plots.
🔢 Matrix Operations
Matrices up to 10×10. Row operations, inverses, determinants, and reduced row echelon form.
🔬 Science & Engineering
Scientific notation, complex numbers, all trig and log functions — everything needed for physics and chemistry courses.
📝 TI-BASIC Programming
Write and run TI-BASIC programs. Useful for automating repetitive calculations or building your own tools.
📋 Tables & Lists
Generate value tables, store data in lists, and use those lists for calculations and statistical analysis.
Who Uses This TI-84 Graphing Calculator
High school students — Covers Algebra 2, Precalculus, AP Calculus, and AP Statistics without needing to carry a physical device or spend $100.
SAT and ACT test prep — The TI-84 Plus CE is one of the most widely allowed calculators on College Board and ACT exams. Practicing here means you learn the exact interface you will use on test day.
College students — Many intro courses in calculus, statistics, and economics allow or require the TI-84. This means one less device to carry to every class.
Teachers and tutors — Pull this up on a projector during a lesson. Students can follow along on their own devices at the same time.
Parents helping with homework — No need to track down a physical calculator. Just open this page and work through problems together.

Frequently Asked Questions
Is this a real TI-84 Plus CE calculator?
This runs the TI-84 Plus CE HTML5 emulator from Texas Instruments, loaded through the TestNav platform. It uses the same engine as the physical device, so calculations match exactly.
Can I use this for SAT or ACT practice?
Yes — it is ideal for practice. Official in-person exams require a physical device, but for prep, homework, and computer-based tests this works perfectly.
Does it work without an internet connection?
You need a connection for the first load to pull the emulator files. After that, most calculations run locally in your browser.
Will my work be saved if I close the tab?
The calculator resets on reload, the same way a physical calculator resets when you remove the batteries. Your zoom level is remembered, but entered data is not stored between sessions.
Is this completely free?
Yes. No subscriptions, no premium tiers, no account needed. Open it and use it.
Can I write and run TI-BASIC programs?
Yes. Press PRGM to open the program menu, then select NEW to start writing. The full TI-BASIC environment is available.
