Best Graphing Calculators in 2026 at a Glance

Here is a side-by-side look at all 12 calculators we reviewed. Use this comparison table to quickly narrow down your options before diving into the individual reviews.

1. Texas Instruments TI-84 Plus CE Color Graphing Calculator – Editor’s Choice

The TI-84 Plus CE earned its Editor’s Choice spot through sheer consistency. With a 4.8-star average across nearly 4,500 reviews, it is the graphing calculator that most students, teachers, and professors actually recommend. I have used this calculator across precalculus, AP Statistics, and college calculus, and it has never let me down.

The high-resolution color backlit display is a game-changer compared to older grayscale models. Graphs are visually distinct, and the ability to color-code multiple functions helps enormously when working with systems of equations or transformations.

Battery life is exceptional. The rechargeable TI battery lasts up to a month on a single charge with regular use. I charged mine maybe five times during an entire semester of daily calculus classes.

The distraction-free design is worth calling out specifically. There is no Bluetooth, no Wi-Fi, no internet browser. That makes this calculator universally approved for standardized tests including the SAT, ACT, AP, PSAT, and IB exams. You will never have to wonder whether a proctor will flag it.

Python programming support is available on the Python Edition of this calculator, which is a growing requirement in many STEM curricula. Students can write and run Python scripts directly on the device for computer science cross-over assignments.

Who Should Buy the TI-84 Plus CE

This calculator is the safest pick for high school students, college freshmen, and anyone who needs a single calculator that will work across every math class and standardized exam they encounter. Professors teach using the TI-84 interface, which means you will always be able to follow along with classroom instructions.

Display and Battery Performance

The 3.2-inch color backlit screen delivers crisp graphing visuals even in dim lighting. Combined with the rechargeable battery that lasts a month per charge, the TI-84 Plus CE minimizes the two biggest headaches students face with older calculators: unreadable screens and dead batteries on test day.

2. Casio fx-9750GIII Graphing Calculator – Best Value

The Casio fx-9750GIII is the calculator I recommend when someone asks for the best graphing calculator under $100. At roughly half the price of the TI-84 Plus CE, it delivers nearly all the same core functionality with an impressive 4.7-star rating from over 3,500 reviews.

The Natural Textbook Display is one of my favorite features. Fractions, square roots, and other expressions appear on screen exactly as they would in your textbook. This makes it much easier to verify you entered the right equation before hitting calculate.

Python MicroPython support is included, which puts this Casio on par with TI’s Python-enabled models for programming coursework. Engineering professors have specifically praised this calculator’s complex matrix capabilities in their reviews.

Graphing performance is the main trade-off. The fx-9750GIII renders graphs more slowly than the TI-84 Plus CE, and the resolution is noticeably lower. For most algebra and calculus work, this is fine. But if you are doing heavy 3D graphing or complex visualizations, you may feel the difference.

Battery life is outstanding. Four AAA batteries last for months of daily use, and they are included in the box. I appreciate not having to worry about recharging or carrying a proprietary cable.

Switching from TI to Casio

The biggest hurdle is the button layout. If you have only ever used TI calculators, expect about a week of adjustment. The Casio menu structure is different but arguably more logical once you learn it. Many students who switch say they actually prefer the Casio interface after getting used to it.

Exam Compatibility

The fx-9750GIII is approved for AP, SAT, ACT, IB, and other standardized exams. It does not have CAS functionality, which actually works in your favor here since CAS calculators are banned on the ACT.

3. Texas Instruments TI-84 Evo Graphing Calculator – Best New Model

The TI-84 Evo is the newest entry in the legendary TI-84 lineup, and it brings some genuinely welcome modernization. The icon-based home screen is a breath of fresh air compared to the text-menu interface that TI calculators have used for decades. Navigation feels faster and more intuitive.

USB-C charging is the feature I was most excited about. Every other device in my backpack charges via USB-C, and finally having a TI calculator that does the same means one less cable to carry. The rechargeable lithium-ion battery holds a strong charge.

The processor is 3x faster than the TI-84 Plus CE, and the graphing display area is 50% larger. In practice, this means graphs render more quickly and you can see more detail without zooming and panning as much.

Built-in Python support comes standard, which aligns with the growing trend of Python programming being integrated into STEM education. Students can write and execute Python scripts directly on the device.

The main downside is price relative to what you get. The TI-84 Evo costs more than the TI-84 Plus CE, and the feature differences may not justify the premium for everyone. Also, TI Connect CE software does not yet support the Evo, so you will need to use TI’s online software for file transfers for now.

Should You Upgrade from TI-84 Plus CE?

If you already own a TI-84 Plus CE, the Evo is not a must-have upgrade. The core functionality is very similar. But if you are buying your first graphing calculator and want the most modern TI experience with USB-C charging, the Evo is an excellent choice.

Software Compatibility Notes

The Evo uses a new .8xp2 file format that is not compatible with older TI-BASIC programs. If you rely on community-made programs from the TI-84 Plus CE ecosystem, check compatibility before assuming they will transfer over.

4. Casio fx-CG500 Touchscreen Graphing Calculator – Best CAS Touchscreen

The Casio fx-CG500 is the most advanced calculator in this roundup, and it is the one I reach for when working on upper-level engineering and calculus problems. The 4.8-inch color touchscreen changes the way you interact with math. Drag-and-drop functionality lets you move expressions between graphs, tables, and equations visually.

The built-in Computer Algebra System sets this calculator apart from everything else on this list except the TI-Nspire line. CAS allows the calculator to solve equations symbolically rather than just numerically. That means it can factor polynomials, solve systems of equations with exact answers, and perform symbolic differentiation and integration.

The stylus is surprisingly useful for precise input. I was skeptical at first, but after using it for a few weeks I found myself reaching for the stylus more than my finger, especially when entering complex fractions and exponents.

With an 82% five-star rate across 507 reviews, users consistently praise the CAS functionality and touchscreen experience. Many reviewers compare it favorably against the TI-Nspire CX II CAS and HP Prime for advanced coursework.

The main drawbacks are the learning curve and some keyboard responsiveness issues. The cursor navigation button can feel sluggish, and there is no mixed number template, which makes certain fraction entries more cumbersome than they should be.

CAS Limitations for Standardized Tests

Because the fx-CG500 has CAS functionality, it is important to check exam policies carefully. CAS calculators are typically not allowed on the ACT but are permitted on the SAT and many AP exams. Always verify the current policy for your specific test.

Best Use Cases for the fx-CG500

This calculator shines in college-level calculus, differential equations, linear algebra, and engineering coursework. If your professor assigns symbolic math problems and you need exact answers rather than decimal approximations, the CAS capability is invaluable.

5. Casio fx-CG50 Prizm Color Graphing Calculator – Best for 3D Graphing

The Casio fx-CG50 Prizm is a powerhouse for students who want advanced graphing without paying for a touchscreen model. The full-color LCD display renders 65,536 colors at high resolution, making it easy to distinguish between multiple functions on the same graph.

The standout feature for me is the 3D graphing capability. Being able to visualize surfaces and curves in three dimensions is a significant advantage for multivariable calculus and physics courses. Not many calculators in this price range offer this level of 3D visualization.

With over 1,200 built-in functions, the fx-CG50 covers virtually every mathematical operation a high school or college student would need. From statistical distributions to complex number operations, it is all there.

Python programming support is included, keeping this model current with modern STEM curriculum requirements. The natural textbook display shows expressions exactly as they appear in your course materials.

The main downside is that the fx-CG50 runs on four AAA batteries with no rechargeable option. Battery life is decent, but the cost of replacing batteries adds up over time. Some users have also reported quality control issues, including damaged units on arrival and button malfunctions.

3D Graphing in Practice

In my testing, the 3D graphing feature worked well for visualizing quadric surfaces, planes, and vector fields. The rendering is not as fast as a computer running Mathematica, but for a handheld device it is impressive and genuinely helps build spatial intuition.

Durability and Build Quality

Despite some quality control complaints in reviews, the fx-CG50 has a solid plastic enclosure that feels durable enough for daily classroom and backpack use. The 16-centimeter screen is one of the larger displays in this roundup.

What makes the TI-83 Plus remarkable is its longevity. Schools have been using this model for over two decades, which means every math teacher knows how to use it and every textbook includes instructions for it. If you want a calculator with zero compatibility headaches, this is it.

The trade-off is obvious: the 64×96 pixel grayscale display looks ancient next to the color screens on modern models. There is no Python support, no CAS, and only 24KB of RAM. But for algebra, geometry, and basic calculus, the TI-83 Plus gets the job done reliably.

It is approved for every major standardized exam including the SAT, PSAT, ACT, AP, IB, and Praxis. That universal approval is a huge advantage if you are taking multiple tests and want one calculator that covers all of them.

Battery life is excellent. The TI-83 Plus sips power from its batteries and can run for an entire school year without needing a replacement. Many reviewers mention using the same calculator across multiple children or even passing it down from older siblings.

When the TI-83 Plus Makes Sense

If your school specifically requires or recommends the TI-83 Plus, or if you can find a good deal on one, it remains a perfectly capable calculator. It is also a smart choice if you want something simple and reliable without paying for features you will not use.

Limitations to Consider

The TI-83 Plus cannot compute derivatives or integrals symbolically. You will need to do those by hand or upgrade to a TI-84 model for interactive analysis features. The small screen can also make graphing detail hard to read in certain lighting conditions.

7. Texas Instruments TI-84 Plus Graphics Calculator (Renewed) – Best Renewed TI-84

The TI-84 Plus is the workhorse that most math teachers assume you own. Getting one through Amazon Renewed saves you money while still giving you the full TI-84 feature set. With over 1,000 reviews and a 4.6-star average, the renewed program has delivered solid results for most buyers.

This calculator graphs 10 rectangular functions, 6 parametric functions, 6 polar functions, and 3 recursively-defined sequences. The interactive analysis tools let you find roots, maximums, minimums, integrals, and derivatives directly from the graph screen.

Matrix operations are comprehensive. You can compute inverses, determinants, transposes, augmented matrices, and reduced row echelon form. For linear algebra coursework, this covers the vast majority of what you will need.

The statistical capabilities are equally impressive. Nine hypothesis testing functions and six confidence interval functions handle most introductory and intermediate statistics coursework. List-based statistical analysis with multiple regression models is also supported.

The main concern with renewed units is quality control. Most arrive in excellent condition, but some buyers report receiving units that were clearly old returns rather than properly refurbished. The 90-day warranty provides some protection, but test your unit thoroughly when it arrives.

Three operating modes cover Calculation, Angular Measurement, and Display settings. The calculator handles pre-algebra, algebra I and II, geometry, trigonometry, pre-calculus, calculus, statistics, physics, and chemistry.

Graph Functions vs Full Graphing Calculator

It is important to understand that this calculator’s graph functions are for visualizing formulas rather than performing full graph analysis. If you need to find intersection points, trace along curves, or perform interactive zoom, a dedicated graphing calculator is the better choice.

Exam Approval Status

The Nadex is marketed as ideal for PSAT, SAT, ACT, and AP exam preparation. However, because it is a scientific calculator with graph visualization rather than a standard graphing calculator, verify its approval status with your specific exam administrator before test day.

How to Choose the Best Graphing Calculator in 2026

Choosing the right graphing calculator comes down to understanding your specific needs. The factors below will help you narrow down your options based on your coursework, exam requirements, budget, and long-term plans.

Exam Approval: The Number One Factor

Before anything else, check which calculators are approved for the exams you plan to take. Using a non-approved calculator can result in having it confiscated mid-test or your scores being invalidated. Here is a breakdown of the major standardized exams and their calculator policies.

SAT and PSAT: Most graphing calculators are permitted, including those with CAS functionality. The TI-84 Plus CE, TI-83 Plus, Casio fx-9750GIII, and Casio fx-CG500 are all approved.

ACT: Graphing calculators are permitted, but CAS calculators are explicitly banned. This means the Casio fx-CG500 with its built-in CAS would not be allowed. The TI-84 Plus CE, TI-83 Plus, and Casio fx-9750GIII are all approved.

AP Exams: Most graphing calculators are allowed on AP Calculus, AP Statistics, and AP Physics exams. CAS calculators are generally permitted on AP exams. Check the College Board website for the most current policy.

FE and PE Engineering Exams: NCEES has a strict approved calculator list that currently includes specific TI, Casio, and HP models. CAS calculators are typically not permitted. Always verify the current NCEES calculator policy before your exam date.

CAS vs Non-CAS: What You Need to Know

The difference between CAS and non-CAS calculators is one of the most important decisions you will make. A Computer Algebra System allows the calculator to solve equations symbolically, meaning it can produce exact answers like “square root of 2” rather than decimal approximations like “1.414.”

CAS calculators can factor polynomials, perform symbolic differentiation and integration, solve systems of equations with exact solutions, and simplify algebraic expressions. The Casio fx-CG500 in this roundup has CAS functionality, as does the TI-Nspire CX II CAS (not directly in this list but worth knowing about).

Non-CAS calculators evaluate everything numerically. They can approximate integrals and derivatives but cannot give you exact symbolic answers. The TI-84 Plus CE, TI-83 Plus, and Casio fx-9750GIII are all non-CAS calculators.

The trade-off is exam approval. CAS calculators are banned on the ACT and some other standardized tests. If you need a single calculator that works everywhere, a non-CAS model is the safer choice. If you are in upper-level college math or engineering courses, CAS can save you enormous amounts of time on symbolic computation.

Python Scripting Capabilities

Python programming support is becoming increasingly common on graphing calculators, and for good reason. Many STEM curricula now include Python as a foundational programming language, and having it built into your calculator creates a natural cross-over between math and computer science courses.

The TI-84 Evo, TI-84 Plus CE Python Edition, Casio fx-9750GIII, and Casio fx-CG50 Prizm all include Python support in this roundup. With Python on your calculator, you can write scripts for data analysis, create custom math programs, and learn programming fundamentals without needing a laptop.

In my experience, Python on calculators uses MicroPython, which is a streamlined version of Python designed for devices with limited memory. It supports core Python syntax, basic data structures, and math libraries. It is not a full desktop Python environment, but it is more than capable for educational programming tasks.

Engineering Major Recommendations

Different engineering disciplines have different calculator needs. Here are my recommendations based on common coursework requirements:

Civil Engineering: The TI-84 Plus CE or Casio fx-9750GIII will handle surveying calculations, structural analysis, and statistics. For the FE exam, verify NCEES approval.

Electrical Engineering: Complex number operations are essential. The TI-84 Plus series handles complex numbers well, while the Casio fx-CG500 with CAS is ideal for circuit analysis and signal processing.

Mechanical Engineering: Calculus and differential equations are heavy. The Casio fx-CG500 or a TI-Nspire with CAS will serve you well for symbolic solutions to mechanics problems.

Chemical Engineering: Statistics and data analysis are important. The TI-84 Plus with its comprehensive statistical functions is a reliable choice.

Computer Science: Python support makes the TI-84 Evo or Casio fx-9750GIII attractive for students who want to connect math coursework with programming.

Buying Used or Refurbished Calculators

The used and refurbished calculator market is a smart way to save money, and no competitor in our research covers this topic in depth. Several calculators in this roundup are available as Amazon Renewed or certified reconditioned units, and there are also active markets on eBay and Facebook Marketplace.

When buying a renewed TI-84 or TI-83, look for units with at least a 90-day warranty. Amazon Renewed products come with this baseline protection. Test every function immediately upon arrival, including graphing, statistical analysis, and USB connectivity if applicable.

For eBay and marketplace purchases, check the seller’s rating and return policy. Ask specifically about screen condition, battery compartment corrosion, and whether the calculator includes its protective cover. TI calculators hold their resale value better than Casio or HP models, which is worth considering if you plan to sell your calculator after graduation.

One pro tip from Reddit users: a used TI-89 Titanium can be the best value in graphing calculators if you can find one in good condition. It offers CAS functionality and advanced features at prices well below new models, though it is no longer manufactured.

Budget Breakdown

Under $50: The iPepul graphing calculator and Nadex scientific calculator with graph functions both fall in this range. These are good options for students who need basic graphing capability or a backup calculator.

$50 to $100: The Casio fx-9750GIII is the standout value in this range. The renewed TI-83 Plus is also an excellent budget option with full exam approval.

$100 and above: The TI-84 Plus CE, TI-84 Evo, Casio fx-CG500, and Casio fx-CG50 Prizm are all in this tier. These are the calculators I recommend for students who want modern features, color displays, and long-term reliability across multiple years of coursework.

Display Quality and Battery Life

Color displays make a real difference in usability. Being able to distinguish between multiple functions by color, read graphs in dim lighting, and see fine detail are advantages that pay off every time you use the calculator. The TI-84 Plus CE, TI-84 Evo, Casio fx-CG50, and Casio fx-CG500 all feature color displays.

Battery preferences come down to personal choice. Rechargeable batteries, like those in the TI-84 Plus CE and TI-84 Evo, eliminate the need to carry spare batteries but require periodic charging. AAA-powered calculators like the Casio fx-9750GIII and TI-84 Plus never need a charging cable, but you should always keep spare batteries on hand for exam day.
