10 Best Scientific Calculators 2025 in the United States

The Texas Instruments TI-84 Plus CE is a solid choice for students and professionals who need a reliable graphing calculator. Its high-resolution, full-color display makes it easy to visualize complex equations and graphs, which is a strong point for users in math and science fields. The option for horizontal and vertical split-screens is especially useful for comparing multiple graphs or data sets side by side. The calculator also boasts a rechargeable battery, which is convenient and environmentally friendly, reducing the need for constant battery replacements.

Additionally, the TI-84 Plus CE comes preloaded with various apps and features like MathPrint, which allows for more intuitive input and output of mathematical expressions. With seven different graph styles and fourteen interactive zoom options, users can customize their visualizations to better suit their needs.

The calculator's lightweight design, while beneficial for portability, may not feel as rugged as some users would prefer. Although it's durable enough for classroom use, more intensive users may want to handle it with care. The calculator's popularity means that you could end up with the Python version, which while beneficial for programming, may not be necessary for everyone.

The Casio fx-300ES Plus 2nd Edition is a robust scientific calculator well-suited for middle school and high school students tackling subjects like math, statistics, and algebra. One of its standout features is the Natural Textbook Display℠, which shows fractions, expressions, and solutions exactly as they appear in textbooks, aiding in better comprehension. With 262 built-in functions, it covers a wide range of mathematical operations, including scientific, exponential, trigonometric, and statistical calculations, equipped to handle various academic needs.

The two-function table capability adds convenience for calculating values for f(x) and g(x) with defined steps, beginning, and ending values, enhancing its utility in function analysis. It also includes a random number generator for added versatility in computations. In terms of power, it's primarily solar-powered with a battery backup, ensuring reliable operation even in low-light conditions, which is advantageous for uninterrupted use. The calculator's build is durable and lightweight, weighing only 5.6 ounces, making it portable for students.

However, the pink color might not appeal to everyone, though it’s a minor aesthetic consideration. Despite its comprehensive functionality, the ease of use could be overwhelming for beginners due to the multitude of features. Additionally, while it has memory functions, it lacks extensive storage capabilities for saving multiple equations or data sets. This makes it a solid choice for students needing a reliable, feature-rich scientific calculator.

The Casio fx-115ESPLUS2 2nd Edition Advanced Scientific Calculator is a highly versatile tool designed for a wide range of scientific and engineering calculations. One of its most notable features is the 16-digit, 4-line LCD display, which provides a clear and accurate representation of expressions and results, mirroring how they appear in textbooks. This makes the calculator easy to use and understand, especially for students and professionals who need to work with complex equations and fractions.

Additionally, the over 280 functions cover a broad spectrum of calculations, including statistics, complex numbers, matrix and vector operations, and more. This makes the calculator suitable for various fields such as mathematics, engineering, and computer science. The multi-replay function is quite handy, enabling users to backtrack and edit previous calculations, which can save time and reduce errors. The solar power with battery backup ensures that the calculator remains functional even under low-light conditions, enhancing its reliability.

Durability is another strong point; the slide-on hard case protects the calculator from damage, making it a good choice for both classroom and fieldwork. However, while the calculator is packed with features, its extensive range of functions may be overwhelming for beginners or those who only need a basic calculator. Also, the reliance on a single LR44 battery for backup power means that users will need to keep spare batteries on hand to avoid interruptions. Despite these minor drawbacks, the Casio fx-115ESPLUS2 is well-built, highly functional, and user-friendly, making it a top choice for anyone in need of an advanced scientific calculator.
