The Casio fx-991CW is my pick if you want one calculator that can carry you through several years of college STEM. It has equation solving, matrices, vectors, statistics, numerical calculus, lots of conversions/constants, and a high-resolution display. itself currently lists it as its top advanced scientific calculator.
For college, the gold standard for scientific calculators comes down to a couple of heavy-hitting, non-programmable models that pack advanced problem-solving features (like matrix calculations, polynomial solvers, and statistical analysis) while still being allowed on rigorous exams like the FE/PE or college finals where graphing calculators are banned.[](https://www.reddit.com/r/EngineeringStudents/comments/16s1n81/what_calculators_do_yall_use/)
The top recommendations depend on your major and depth of math:
Widely considered the king of college scientific calculators, especially for engineering, physics, and math majors. It features a MultiView display that lets you see multiple calculations at once, excellent matrix/vector capabilities, a brilliant solver for equations and polynomials, and a very logical user interface.
Casio's flagship advanced scientific line. It features a high-resolution natural textbook display, intuitive menu systems, numeric integration/differentiation, vector/matrix calculations, and even a basic spreadsheet mode. It's lightning-fast and punches way above its price point.
If you aren’t going into a heavy STEM field (e.g., general education requirements, basic stats, or lower-level algebra), this budget-friendly option handles fractions, standard regressions, and basic formulas with a textbook display for a fraction of the cost.[](]()](][4]
🥇 Best for engineering/technical majors: TI-36X Pro

Taking a class requiring graphing
Wait and check the syllabus before buying
One important caveat: don't automatically buy a graphing calculator. Many college classes—and some professional exams—restrict calculators, while a good non-graphing scientific calculator is sufficient for a lot of STEM coursework. Always check your syllabus/exam rules first.
If you tell me your major (e.g. engineering, nursing, business, chemistry, computer science) and your budget, I can pick the exact one I'd buy.
If you tell me your college major or the specific math classes you need to take, I can narrow down whether you need a scientific calculator or a full graphing calculator.
1. Casio fx-991CW — best all-around choice
It’s a non-programmable, non-graphing calculator with a high-resolution display and a very broad feature set: complex numbers, matrices, vectors, statistics/regression, distributions, equation solving, numerical derivatives/integrals, and spreadsheet functionality. It also has solar + battery power.
2. TI-36X Pro — particularly good for engineering/science
TI describes it as its higher-level scientific calculator, and it includes a MultiView display, MathPrint, equation/system solvers, and other advanced math/science functionality. TI specifically provides a guidebook for its higher-level math and science capabilities.
3. Casio fx-115ES Plus 2nd Edition — good cheaper option
A solid choice if you want an advanced scientific calculator without paying for the newest model. It's particularly useful for algebra, trig, calculus and statistics.
What I'd buy
If your college courses are engineering, physics, chemistry, math, computer science, or other STEM, I'd narrow it to the fx-991CW vs. TI-36X Pro.
If you tell me your major + the classes you're taking (e.g. engineering calculus, chemistry, physics), I can compare the two specifically for your coursework and find the current cheapest reputable listing.
If you want one scientific calculator that will cover most college math/science courses, I’d get the Casio fx-991CW ClassWiz.

Quick Buying Tips for College:
Check the syllabus first: Some strict math or engineering professors ban programmable or solver-capable scientific calculators on specific exams (forcing you down to a basic model like the TI-30XIIS ), while others require them.
Scientific vs. Graphing: Don't buy an expensive graphing calculator (like the TI-84 Plus CE ) unless a specific class demands it. Many modern engineering and math classes actually prefer or only allow advanced scientific calculators because graphing tools are restricted on exams.
What is your college major or specific math/science classes you need to take? I can tell you whether you can get away with a basic model or if you need an advanced solver.
