Choosing the right calculator for school is not always obvious. Some students only need a reliable scientific calculator for everyday math and science classes, while others may need a more advanced graphing calculator for pre-calculus, calculus, engineering, or higher-level STEM courses.
Below are two back-to-school calculator picks: a budget scientific calculator for most students and an advanced graphing calculator for more demanding coursework.
Quick note: Always check your class, teacher, syllabus, or exam calculator policy before buying.

| Calculator | Best For | Calculator Type | Price Level | Good For | Skip It If |
|---|---|---|---|---|---|
| TI-30XS MultiView | Most students who need a dependable school calculator | Scientific calculator | Budget | Algebra, chemistry, physics, general science, everyday math | You need graphing features or advanced STEM tools |
| TI-Nspire CX II CAS | Advanced STEM students | Graphing calculator with CAS | Advanced | Pre-calculus, calculus, engineering, advanced math, physics, statistics | Your class or exam does not allow CAS calculators |
Budget Pick: TI-30XS MultiView
The TI-30XS MultiView is the safer budget pick for most back-to-school shoppers. It is a practical scientific calculator for students who need something affordable, reliable, and suitable for common math and science classes.
It makes the most sense for:
- Middle school and high school math
- Algebra
- Geometry
- Chemistry
- Physics
- General science classes
- Everyday homework and classroom use
The main advantage is simplicity. Most students do not need a high-end graphing calculator unless a class specifically requires one. For regular math and science work, the TI-30XS MultiView is likely the better value.
Best for: students who need a dependable calculator without paying for advanced graphing features.
Skip it if: your course requires graphing, calculus tools, CAS features, or a specific graphing calculator model.
Advanced Pick: TI-Nspire CX II CAS
The TI-Nspire CX II CAS is the advanced option for students taking more demanding math, science, or STEM courses. It is built for graphing, solving, exploring equations, and handling more complex coursework.
It makes the most sense for:
- Pre-calculus
- Calculus
- Advanced algebra
- Engineering classes
- Physics
- Statistics
- Higher-level STEM coursework
This is not the calculator I would recommend for every student. It is more expensive, and many students will not use its full feature set. But for advanced math and STEM classes, it can be a serious upgrade over a basic scientific calculator.
Important: Because this is a CAS calculator, check your class or exam rules carefully before buying. Some exams and teachers restrict CAS calculators.
Best for: students who specifically need an advanced graphing calculator for higher-level math or STEM work.
Skip it if: you only need a basic calculator for regular math and science classes.
Which One Should You Buy?
For most students, start with the TI-30XS MultiView.
It is the better first choice if the school supply list simply says “scientific calculator” or if the student is taking general math, science, chemistry, physics, algebra, or similar classes.
Choose the TI-Nspire CX II CAS only if the class specifically requires or strongly benefits from an advanced graphing calculator.
A simple way to decide:
| Situation | Better Choice |
|---|---|
| Student needs a basic school calculator | TI-30XS MultiView |
| Student is taking regular math or science | TI-30XS MultiView |
| Student needs graphing features | TI-Nspire CX II CAS |
| Student is taking calculus or advanced STEM | TI-Nspire CX II CAS |
| You are unsure what the teacher allows | Check the class policy first |
My recommendation: do not buy the expensive graphing calculator unless you know the student actually needs it. For many students, the budget scientific calculator is the smarter buy.
Check Class or Exam Calculator Rules First
Before buying either calculator, check:
- the school supply list
- the class syllabus
- the teacher’s calculator policy
- exam calculator rules
- whether CAS calculators are allowed
This is especially important for advanced graphing calculators. A calculator can be powerful and still not be allowed for a specific class or test.
