About Us

Who We Are

freeti84calculator.com is a free online TI-84 Plus CE calculator built for students, teachers, and test-takers. Our tool runs entirely in your web browser — no downloads, no installation, and no account required.

We are students, developers, and educators who believe powerful math tools should be free for everyone. Our online TI-84 Plus CE emulator recreates the real calculator experience right in your browser: the same buttons, the same menus, the same functions — with zero downloads, zero cost, and zero signup.

Our Mission

Our mission is to make powerful mathematical tools accessible to everyone. Whether you are working through algebra homework, preparing for the SAT or ACT, or teaching a classroom of students, you should have access to a reliable TI-84 calculator without cost or barriers.

A physical TI-84 Plus CE is required or recommended in thousands of classrooms, yet its price puts it out of reach for many families. We built this free online alternative so that any student with an internet connection can practice graphing, statistics, and algebra on a faithful TI-84 experience. Whether you are preparing for the SAT, working through AP Statistics, or just doing tonight’s homework, this site exists to help you succeed.

What You Can Do Here

Our calculator replicates the core TI-84 Plus CE experience, including graphing in function, parametric, polar, and sequence modes, scientific and algebraic calculations, statistics and regression, matrices, lists, and probability distributions. We also publish free step-by-step guides to help you master your calculator for exams and coursework.

Graph equations and trace functions, run statistical tests like t-tests and z-tests, compute probabilities with normalcdf and invNorm, perform linear regression, work with fractions and decimals, and explore matrices — all with an interface that mirrors the real TI-84 Plus CE. Our step-by-step guides walk you through the most common tasks and fix the most frustrating errors, from blank graphs to unexpected fraction answers.

Who This Site Is For

High school students use our calculator for algebra, geometry, and pre-calculus homework. AP Statistics and AP Calculus students rely on it for distributions, regressions, and derivatives. SAT and ACT test-takers practice the exact keystrokes they’ll need on exam day. Teachers project it in classrooms as a free alternative to expensive hardware. Adult learners and GED students use it to rebuild math confidence without buying a device. If you need a TI-84 and don’t have one in your bag, this site is for you.

Our Promise

This calculator will always be free — no trials, no paywalls, no accounts. We don’t sell your data, and we keep the site fast and simple so it works on school Chromebooks and old laptops alike. We are not affiliated with Texas Instruments; TI-84 is a trademark of Texas Instruments Incorporated, and our emulator is an independent educational project. If something isn’t working, tell us through the contact page — we actually read every message.

Bookmark this page, share it with a classmate who needs it, and check our guides library whenever you get stuck. Learning math is hard enough — paying for the tools shouldn’t make it harder.
