Should I choose Casio CG50 or Casio CG100?

Verdict: Choose Casio fx-CG50 first if you need dual-language programming (Casio BASIC and Python), dedicated Geometry and Picture Plot apps, and 16 MB of Flash memory. Choose Casio fx-CG100 if you want the modernized ClassWiz catalog menu system and USB-C connectivity.

The Casio fx-CG50 remains the superior choice for advanced mathematics and programming versatility with 16 MB of Flash storage and Casio BASIC support, while the Casio fx-CG100 offers a modernized ClassWiz menu layout and USB-C connectivity.

While both calculators share identical 384 x 216 resolution displays with over 65,000 colors, MicroPython v1.9.4 execution, 61 KB of RAM/program memory, and 170-hour battery life on 4 AAA batteries, the Casio fx-CG50 delivers broader functional depth. The Casio fx-CG50 includes 16 MB of Flash storage, dual support for Casio BASIC and Python, a 999-row by 26-column spreadsheet, Picture Plot, and a dedicated Geometry app. In contrast, the Casio fx-CG100 modernizes physical hardware with USB-C and replaces the F1–F6 function keys with a streamlined ClassWiz catalog menu, but drops Casio BASIC in favor of a strictly Python-only programming environment.

Best for Casio CG50

  • Users who require legacy Casio BASIC programming alongside MicroPython v1.9.4
  • Students needing dynamic geometry and Picture Plot visual analysis tools
  • Extensive storage workflows requiring 16 MB of Flash ROM for add-ins and custom datasets
  • Users accustomed to dedicated 6-button function key (F1–F6) navigation
  • Spreadsheet-heavy calculations requiring up to 999 rows by 26 columns

Best for Casio CG100

  • Students transitioning from scientific calculators who prefer the modern ClassWiz hierarchical catalog UI
  • Users prioritizing modern USB-C physical connectivity
  • Exam-takers wanting streamlined Exam Mode activation directly from the HOME menu interface
  • Standardized 3D graphing across 5 core geometric templates (sphere, cylinder, plane, cone, line)

When not to compare directly

Do not compare them directly on standardized exam eligibility or basic display clarity, as both feature matching 384 x 216 resolution screens with over 65,000 colors, identical ~170-hour battery life on 4 AAA batteries, and identical approvals for SAT, ACT, AP, PSAT, and IB testing.

What are the key differences between Casio CG50 and Casio CG100?

  • User Interface & Navigation

    While the Casio fx-CG50 relies on 6 dedicated function keys (F1–F6) for navigating its traditional icon menu, the Casio fx-CG100 replaces this with a modern ClassWiz-style hierarchical catalog and directional menu system on the same 384 x 216 resolution screen.
