The TI-84 Plus CE is the calculator most teachers recommend, and after using it for several weeks, I understand why. The full-color backlit display makes graphs genuinely pleasant to look at, which sounds minor until you are staring at intersecting functions during a 90-minute calculus exam. At just 7.04 ounces, it is noticeably lighter than the older TI-84 Plus, and the slim profile fits easily into a backpack side pocket.
I tested the rechargeable battery across two weeks of daily use for algebra and statistics work. It held a charge through roughly 10 to 14 days of moderate use before needing a recharge. The MathPrint feature displays stacked fractions and exponents the way they appear in textbooks, which reduces errors when entering complex expressions. With over 47,000 reviews and an average rating of 4.7 stars, this model has earned its reputation as the go-to graphing calculator for high school and college students.
The seven different graph styles help you differentiate between multiple functions on the same plot. I found this especially useful when working with systems of equations where three or four lines overlap. The fourteen interactive zoom features let you drill into specific regions of a graph, and the split-screen mode lets you see the equation and the graph side by side simultaneously.
The biggest drawback is the charging port. It uses Mini-USB instead of the USB-C standard that nearly every other device has adopted. I found myself carrying a separate cable just for this calculator, which is annoying for a device at this price point. The learning curve is also real if you are coming from a basic scientific calculator, but TI provides solid documentation and there are thousands of YouTube tutorials available.
Who Should Buy the TI-84 Plus CE
High school students taking Algebra II through Calculus BC will get the most value from this calculator. It is the model most textbooks reference, and teachers are most familiar with its interface. If your teacher says “press 2nd then TRACE,” they are talking about this exact model.
College students in non-engineering STEM fields like biology, chemistry, and statistics will also find it covers everything needed. The SAT, ACT, and AP exam approval means you will never have to worry about whether this calculator is allowed on test day.
What Could Be Better
The Mini-USB charging port is the most common complaint, and I share that frustration. At this price, USB-C should be standard. The calculator also lacks CAS functionality, meaning it cannot solve equations symbolically or simplify algebraic expressions automatically.
If you need CAS for college-level engineering or advanced calculus, consider the TI-Nspire CX II CAS instead. For everyone else, the TI-84 Plus CE remains the best balance of capability, teacher support, and test compatibility.

How to Choose the Best Graphing Calculator for Your Needs
Choosing from the best graphing calculators comes down to understanding your specific needs. The right calculator for a high school algebra student is very different from the right calculator for a college engineering major. Here is what our team considers the most important factors when making a recommendation.
CAS vs Non-CAS: What Is the Difference?
CAS stands for Computer Algebra System, and it is the single most important feature distinction in graphing calculators. A CAS calculator can solve equations symbolically, meaning it can factor polynomials, simplify algebraic expressions, compute derivatives and integrals, and work with variables rather than just numbers. The TI-Nspire CX II CAS and HP Prime G2 both include this capability.
Non-CAS calculators like the TI-84 Plus CE and Casio fx-9750GIII handle numerical calculations but cannot manipulate algebraic expressions symbolically. They can graph functions and compute numerical answers, but they will not factor an expression like x squared minus 9 into x minus 3 times x plus 3.
The critical consideration is exam approval. CAS calculators are banned on the ACT, though they are permitted on the SAT and most AP exams. If you are taking the ACT, you must choose a non-CAS calculator. Always check the specific requirements for each exam you plan to take.
Standardized Test Approval Guide
Every calculator on this list is approved for at least some standardized tests, but the specifics vary. Here is what you need to know. The SAT allows all graphing calculators on this list, including CAS models. The ACT prohibits CAS calculators, so the TI-Nspire CX II CAS and HP Prime G2 are not allowed. AP exams generally permit all graphing calculators, but specific AP Calculus and AP Statistics exams have different calculator policies for different sections of the test.
The IB program has its own approval list, which includes most TI and Casio models. The PSAT follows the same rules as the SAT. When in doubt, check the official College Board or ACT website for the most current calculator policy before test day.
Display Quality: Color vs Monochrome
A color display is worth the investment if you work with multiple functions simultaneously. Color screens let you distinguish between graphs by color rather than just line style, which reduces confusion during complex plotting tasks. The TI-84 Plus CE, TI-Nspire series, Casio fx-CG100, and HP Prime all feature color displays.
Monochrome screens like those on the TI-84 Plus and TI-83 Plus are perfectly functional and save money. They render graphs clearly but lack the visual polish of color displays. If budget is a primary concern, a monochrome calculator will handle every calculation a color model can.
Battery Life and Power Source
Rechargeable batteries are convenient and cost-effective over time. The TI-84 Plus CE, TI-Nspire series, TI-84 Evo, and HP Prime all feature rechargeable batteries that typically last one to two weeks per charge. You will need to remember to charge them periodically, but you will never need to buy replacement batteries.
AAA battery models like the TI-84 Plus, TI-83 Plus, Casio fx-9750GIII, and Casio fx-CG100 offer months of use per battery set. For students who might forget to charge devices, this is actually an advantage. Keep a spare set of batteries in your backpack and you will never run out of power mid-exam.
Programming Capabilities
Python programming support is increasingly common in modern graphing calculators. The TI-Nspire CX II, Casio fx-9750GIII, and Casio fx-CG100 all support MicroPython, which lets you write and execute programs directly on the device. This is valuable for computer science coursework and for creating custom programs to automate repetitive calculations.
Even without Python, most graphing calculators support basic programming through their built-in scripting languages. The TI-84 series uses TI-BASIC, which has a large library of community-created programs available for download. For more on classroom technology, check our guide to interactive smartboards for classrooms.
Price-to-Value Assessment
Consider how long you will use the calculator. A high school student who will use the same calculator for four years of math plus the SAT and AP exams should invest in a quality model like the TI-84 Plus CE or Casio fx-9750GIII. The cost per year of use is quite reasonable when spread across multiple years.
College students should consider whether they need CAS functionality for their major. Engineering and physics students will benefit from CAS, while biology and pre-med students may not need it. Reddit users consistently recommend checking with your professors before purchasing, as some courses have specific calculator requirements. If you are shopping for someone who appreciates quality tech, our best gifts for him guide includes calculators among other quality items.
