10 Best Graphing Calculators 2026 in the United States

The Texas Instruments TI-84 Plus is a solid choice for students and professionals needing a reliable graphing calculator. Its LCD screen offers clear, 10-digit precision with additional exponent display, making it easy to read both simple and complex calculations. It can graph multiple types of functions at once, including rectangular, polar, and parametric, which is great for a variety of math and science courses. Users also get useful features like interactive graph analysis (finding roots, maximums, and integrals), matrix operations, and a wide range of statistical tools, supporting up to 999 list elements and multiple regression models.

While the processing power handles these tasks smoothly, the calculator relies on a single CR2 battery, so users should be prepared to replace it occasionally, as it doesn’t have rechargeable or USB power options. Memory is sufficient for storing multiple functions and matrices, though it’s not expandable. Connectivity is limited, as this model doesn’t support wireless or USB data transfer, which might be a drawback if you want to connect to computers or other devices. The user interface is straightforward and familiar to many, but newer users might need some time to learn the menu system and key functions.

This model is well-suited for high school and college students tackling algebra, calculus, and statistics, offering strong software functionality without overwhelming complexity. For those needing advanced connectivity or a touchscreen interface, newer models might be preferable. For most users, the TI-84 Plus successfully balances functionality, ease of use, and portability in a durable, battery-powered package.

The Texas Instruments TI-84 Plus CE Color Graphing Calculator is a standout option for students and professionals who need a reliable graphing calculator for math and science coursework. Its high-resolution, full-color backlit display makes it easy to view graphs and data, which is a significant advantage for visual learners. The ability to use horizontal and vertical split-screen options enhances productivity, allowing users to work on multiple calculations simultaneously.

One of its key strengths is its processing power and memory, which can handle complex calculations and store multiple functions and graphs. The rechargeable battery is another highlight, providing longevity and convenience over traditional battery-operated models.

Users will appreciate the variety of preloaded apps and interactive features, such as MathPrint and customizable graph styles, which make it suitable for various math levels, from high school to college. The lightweight design adds to its portability, making it easy to carry around in a backpack. However, there are a few drawbacks. While the calculator is designed to meet educational needs, some users may find its interface slightly less intuitive compared to newer models on the market. Potential buyers should also note that the calculator is primarily focused on mathematics and may not be suitable for advanced programming or engineering tasks. Lastly, while the calculator is durable, its price point can be a bit high for casual users or those who only need basic functions. The TI-84 Plus CE is excellent for dedicated students and professionals who require a powerful graphing calculator, but might not be the best choice for those seeking an all-in-one solution or those on a budget.

The Texas Instruments TI-84 Evo graphing calculator offers several improvements that make it a strong choice for students and anyone needing a dependable graphing tool. Its 2.8-inch high-resolution LCD screen is notably larger than many similar models, providing about 50% more space for graphs and equations, which helps in understanding math and data visually. The processor is three times faster, so calculations and graphing run more smoothly and quickly, reducing wait times during use. The rechargeable lithium-ion battery with USB-C charging is a practical upgrade, meaning you don’t need to keep buying disposable batteries and can easily power up the device. User interface improvements, like icon-based navigation, make it easier to find functions without getting lost in menus, which is helpful for those new to graphing calculators. This model is approved for major standardized tests like the SAT and ACT, ensuring it meets important exam requirements.

Weighing under 10 ounces, it’s portable but not the lightest option available. The TI-84 Evo serves as a solid, user-friendly graphing calculator especially suited for high school and early college students who need reliable performance on exams and classwork without complicated features.
