Best Graphing Calculators in 2025: Top 3 Compared
By Emma Brooks · July 8, 2025 · 6 min read
Whether you’re tackling algebra, calculus or AP physics, the right graphing calculator can make a huge difference. Here we compare three of the most popular models available in 2025. Texas Instruments’ TI‑84 Plus CE has become the de facto standard for high‑school exams thanks to its color screen, rechargeable battery and easy‑to‑use MathPrint interface. The more powerful TI‑Nspire CX II offers faster performance, dynamic graphs and Python programming support for ambitious students. Casio’s fx‑9750GII remains a budget‑friendly option with a straightforward interface and exam approvals, though its monochrome display and limited memory hold it back.
Which One Should You Get?
- Best for Standardized Tests & Classroom Use – TI‑84 Plus CE Color Graphing Calculator – ideal for high‑school students who need a reliable, exam‑approved calculator with a color display and intuitive interface.
- Best for STEM Enthusiasts & Programmers – TI‑Nspire CX II Color Graphing Calculator (Student Software) – great for advanced high‑school and college students who want powerful graphing, programming capabilities and dynamic visuals.
- Best for Budget‑Conscious Learners – Casio fx‑9750GII Graphing Calculator – perfect for students who need a simple, affordable graphing calculator for introductory math courses and standardized tests.

Frequently Asked Questions
Can the TI‑84 Plus CE be used on the ACT and SAT?
Yes. The TI‑84 Plus CE is approved for use on major standardized exams, including the PSAT/NMSQT, SAT, ACT, IB and AP tests.
Does the TI‑Nspire CX II have a computer algebra system (CAS)?
No. The CX II model reviewed here does not include a CAS, which allows symbolic manipulation. Texas Instruments sells a separate CX II CAS model, but it may be restricted on some standardized tests.
Are AAA batteries still practical for graphing calculators?
AAA batteries, like those used in the Casio fx‑9750GII, are inexpensive and easy to replace. Some students prefer them because you can swap in fresh batteries during a long exam instead of relying on a recharge.
Which calculator offers the best programming capabilities?
The TI‑Nspire CX II leads here, supporting both TI‑Basic and Python programming. The TI‑84 Plus CE allows TI‑Basic and some apps but lacks Python, while the Casio fx‑9750GII has only basic programming without a modern language.
Is a color screen necessary on a graphing calculator?
Color screens, like those on the TI‑84 Plus CE and TI‑Nspire CX II, make graphs easier to interpret and allow shading and multiple functions in different colors. However, monochrome models like the Casio fx‑9750GII are lighter on the wallet and still handle standard graphing tasks just fine.
