TI-84 Calculator Online
Carrying a $130 calculator to class, or losing it the week before finals, is a problem most students only solve once. This one lives in your browser instead — open a tab and it’s ready to go.
What Makes This Calculator Different
Most online tools are just a picture with a link to a PDF manual. This one runs the real TI 84 Plus CE menu system, keystroke by keystroke.
Faithful to Physical Device
The same [2nd], [MODE], [STAT], and [GRAPH] sequence as the physical device, not a simplified web version.
Cross Device by Design
Runs equally well on a Chromebook, a phone between classes, or a desktop at home — whatever’s in front of you.
Complete Function Library
nDeriv, fnInt, STAT TESTS, hypothesis testing, matrix operations, and the TVM Solver, all included.
Nothing to Sign Up For
No card, no trial period, no locked features behind a paywall.
Classroom Embed Ready
A single iframe line embeds the whole interface into an LMS page or class blog.
Built Around What You’re Actually Studying
The sections below map to coursework, not just abstract menu categories — each one reflects how the function set gets used in a real class.
Algebra & Pre-Calculus
Plot linear and quadratic functions, find roots and intersections, and explore transformations of a parent function.
Calculus
Use nDeriv for derivatives and fnInt for definite integrals. Draw piecewise and parametric functions, then find limits visually with TRACE and ZOOM.
Statistics & Data Analysis
Run 1-Var Stats, linear regression, and hypothesis tests including Z-test, T-test, chi-square, and ANOVA, straight from the STAT menu.
Standard deviation walkthrough →Trigonometry
Plot sine, cosine, and tangent in degree or radian mode, and explore unit circle relationships in parametric mode.
Financial Math — TVM Solver
Calculate loan payments, mortgage amortization, and investment growth through [APPS] > Finance > TVM Solver.
Full TVM Solver guide →Physics & Engineering
Solve kinematics equations with [MATH][SOLVER], handle matrix systems with rref, and fit data with QuadReg.
Who Tends to Reach for This
High School
Preparing for AP exams, the SAT, or the ACT without spending $130 or carrying extra hardware.
SAT/ACT/AP guide →College
Statistics, calculus, linear algebra, and econometrics — on whatever device you have open.
Teachers & Professors
Project onto a smartboard for live demos, or embed in a class website with one line of code.
Teacher’s guide →Parents
Help with homework using the same interface your child’s teacher references, no purchase needed.
Tutors & Test-Prep
Standardize on one consistent interface across every student and session.
Finance & Engineering
Quick TVM calculations, matrix operations, and regression without opening full spreadsheet software.
Before You Choose: TI 84 Comparisons That Matter
Vs Physical TI-84 Plus CE
The browser version matches the physical device on menus, keystrokes, and core functions. Where it differs is exam eligibility: most standardized tests that allow a physical device, not a browser simulator. For homework, classroom demos, and building keystroke familiarity, the two are functionally identical.
Full comparison →Vs Desmos
The TI84 covers statistics, calculus, and the exact menu structure most exams expect. Desmos is built purely for visual graphing and equation exploration. Which one wins depends on what you’re using it for.

Is this Calculator free?
Yes. There’s no subscription, no account, and no trial period. Open the page and use it.
Can I plot equations on it?
Yes, the TI-84 Online on this site recreates the physical device’s interface right in your browser, so you can plot equations without any download or install.”
Does it work on mobile devices?
Yes, it’s fully responsive and runs in any mobile browser without an app install.
Is a physical calculator or the browser version allowed in exams?
Physical TI 84 calculators are allowed on many standardized tests, but browser-based simulators generally are not permitted during the actual exam. Always check your specific test’s policy in advance — this tool is best used for practice and homework, not as your exam-day.
Is Desmos better than a TI 84 for the Digital SAT?
For the Digital SAT specifically, Desmos is built into the test interface and many students find it faster for graphing-heavy questions. The TI 84 remains the standard for classes and exams that require a dedicated handheld-style device. See the Desmos vs. TI-84 comparison above for a full breakdown.
What’s the difference between the TI-84 Plus and Plus CE?
The Plus CE is the newer model, with a slimmer design, a rechargeable battery, and a higher-resolution color screen. The original Plus uses AAA batteries and a monochrome display. See the Plus vs. Plus CE comparison above for the full feature breakdown.
