Best Overall: TI-84 Plus CE
The TI-84 Plus CE continues to be the default recommendation in most high school classrooms because teachers already know its menu system and can troubleshoot quickly. It handles graphing, statistics, and basic programming without requiring students to learn an entirely new interface each year. The color screen makes it easier to distinguish multiple functions on the same graph, and the rechargeable battery removes the need for constant AA replacements.
Find it at major retailers such as Amazon, Walmart, and Best Buy.
Best Budget Pick: Casio fx-9750GIII
Families looking to save money without sacrificing core graphing features often choose the Casio fx-9750GIII. It covers the same algebra and calculus needs as more expensive models and runs on standard AAA batteries that are easy to swap between classes. The learning curve is gentle for students who only need graphing and statistical functions rather than advanced symbolic algebra.
Check current pricing and availability at Target or Amazon.
Best for Advanced Courses: TI-Nspire CX II
Students enrolled in AP Calculus BC or planning to keep the calculator through college may benefit from the TI-Nspire CX II. Its computer-algebra system can solve equations symbolically and the larger high-resolution screen supports more detailed graphs and spreadsheets. The model also includes a built-in rechargeable battery and USB connectivity for transferring data between home and school.
Available through Best Buy and Walmart.

FAQ
Do all high schools require the same graphing calculator?
Requirements vary by district and teacher preference, so it is best to ask before purchasing. The TI-84 series remains the most universally accepted model across U.S. high schools.
Can a student use a graphing calculator on the SAT or ACT?
Yes, both the TI-84 Plus CE and TI-Nspire CX II are permitted, along with the Casio fx-9750GIII. Always double-check the latest test guidelines the year your student sits for the exam.
Is it worth buying a more expensive model for regular classes?
For standard algebra and geometry, the TI-84 Plus CE or Casio fx-9750GIII is usually sufficient. Students only need the higher-priced TI-Nspire if they are taking multiple AP math or science courses that benefit from its advanced features.
