Technology in classrooms may be evolving, but one item that has remained a constant is the best scientific calculators. Scientific calculators continue to not only be a valuable aid in completing complex math equations but also in providing an additional teaching tool in the classroom and at home.

Scientific calculators have several features, including helping students and professionals do floating-point arithmetic, logarithmic functions, exponential functions, trigonometric functions and giving fast access to several commonly used mathematical functions, like Pi.

Scientific calculators are often grouped with graphing calculators, but we’ve focused specifically on non-graphing scientific calculators. You might wonder why you’d choose a scientific calculator over a graphing calculator, which is capable of performing far more functions. There are several key reasons.

Scientific Calculators Vs. Graphing Calculators

Scientific calculators are less expensive, so if you don’t need all the functions of a graphing calculator, you might opt to save money by sticking with a scientific calculator. There are also places you can’t use a graphing calculator, such as during some tests. For example, the National Council of Examiners for Engineering and Surveying (NCEES) engineering exam permits several scientific calculators, but no graphing calculators. There are other school tests where this may be the case as well. We’ve included several of the approved NCEES calculators on this list, including the HP 35s, as well as models from Casio and Texas Instruments.

From junior high to college students, as well as professionals in the medical and surveying field, finding the right scientific calculator suited to your needs can make a huge difference in one’s success. Here are the best scientific calculators that fit the bill.


1. HP 35s Scientific Calculator


With over 800 memory registers and 100 built-in functions, the HP 35s Scientific Calculator is ideal for high school and college students, as well as professionals working in medicine, engineering, surveying and various scientific fields.
