How to Choose the Best Scientific Calculator in 2026

Choosing from the best scientific calculators comes down to five key factors. Here is what to evaluate before making your decision.

Display Type: Natural Textbook Display vs MultiView

Display type is the single biggest factor in day-to-day usability. Natural Textbook Display, found on Casio models, shows fractions, roots, and exponents exactly as they appear in textbooks. TI’s MultiView shows multiple calculations on one screen so you can compare results. Both approaches are effective, but students who struggle with reading notation may prefer the textbook-style display.

For graphing calculators, color displays like the TI-84 Plus CE and HP Prime G2 make it much easier to distinguish between multiple plotted functions. Monochrome graphing screens like the Casio fx-9750GIII work but require more effort to interpret.

Exam Compatibility: Know Before You Buy

Not every calculator is allowed on every exam. The SAT, ACT, AP, IB, and NCEES FE and FS exams each have their own approved calculator lists. The ACT specifically bans calculators with CAS functionality, which eliminates the TI-Nspire CX II CAS and HP Prime G2 for ACT test-takers. Always verify your calculator against the official exam policy before test day.

For maximum flexibility, the TI-36X Pro and Casio fx-115ES Plus are approved for the widest range of exams including the NCEES engineering exams. If you only need a calculator for the SAT and AP exams, nearly every model in this guide qualifies.

Power Source: Solar, Battery, or Rechargeable

Solar power with battery backup is the most reliable setup for scientific calculators. Models like the TI-30XIIS, TI-30XS MultiView, Casio fx-115ES Plus, and Sharp EL-531TGBDW all use this approach. The solar panel handles most situations, and the battery kicks in during low-light conditions.

Graphing calculators typically require more power and use either disposable AAA batteries or rechargeable lithium-ion packs. The TI-84 Plus CE and TI-Nspire CX II CAS both use rechargeable batteries that last one to two weeks per charge. The Casio fx-9750GIII uses 4 AAA batteries that last for months.

Number of Functions and Computational Power

For basic high school math, a calculator with 250 or more functions covers everything you need. The Casio fx-300ES Plus with 262 functions and the Sharp EL-531TGBDW with 273 functions are both sufficient for algebra through precalculus.

For engineering and advanced STEM coursework, look for calculators with equation solvers, numerical integration and differentiation, matrix operations, and complex number support. The TI-36X Pro and Casio fx-115ES Plus both offer these features without the cost or exam restrictions of a graphing calculator.

Brand Choice: Texas Instruments vs Casio vs HP

Texas Instruments dominates the US education market, and many teachers structure their instruction around TI calculators. If your teacher or textbook references specific calculator instructions, choosing a TI model reduces friction. The TI-30XIIS, TI-30XS MultiView, TI-36X Pro, and TI-84 Plus CE are the most commonly referenced models.

Casio calculators often offer more features per dollar. The fx-115ES Plus matches the TI-36X Pro in capability at a similar price, and the fx-9750GIII provides graphing functionality at half the cost of a TI-84. HP calculators appeal to professionals who want premium build quality, touchscreen interfaces, and RPN support.
