The fx-CG50AU is CASIO’s next-generation 3D colour graphic model that carries on the tradition of innovation.
The CASIO fx-CG50AU graphing calculator hosts the same great features of its predecessor – the fx-CG20AU, but also includes a new 3D graphing function, catalog function and E-CON4 application.
It also has 4.5 MB of storage memory built-in, the same as the fx-CG20AU. For existing users, the new machine operates the same way but with improved technology and faster calculation.

FAQs
The fx-1AU GRAPH will replace the fx-CG50AU following its release in July 2025. We will still have the CASIO fx-CG50AU graphing calculators for sale until 2026, after which we encourage schools to transition to the newer model.
Yes! The CASIO fx-CG50AU graphing calculator is approved for use in the IBDP programme as well as many Australian state-based exam authorities.
Approval depends on the specific exam body, so it is recommended to check the latest approved calculator list for your state or programme. Even as the model is being discontinued, it will continue to be supported in exams while it remains on approved lists.
Yes. The CASIO fx-CG50AU graphing calculator remains approved for use in many Australian exam authorities and international programmes such as the IBDP. Approval depends on the specific exam body, so it is recommended to check the latest approved calculator list for your state or programme.
Even as the model is being discontinued, it will continue to be supported in exams while it remains on approved lists.
CASIO regularly updates its calculator range to reflect changes in curriculum requirements and classroom use. Following the release of newer models with updated functionality, the fx-CG50AU is being phased out and replaced by the fx-1AU GRAPH.
The CASIO fx-CG50AU graphing calculator is the Australian-specific version of the fx-CG50. It includes settings, features and approvals that align with Australian curriculum requirements and exam authorities, making it suitable for use in local classrooms and assessments.
Both models share the same core functionality. However, the fx-CG50AU is being discontinued, with 2026 confirmed as the final year it will be available for purchase. Please transition to the fx-1AU GRAPH, which is designed to meet current Australian curriculum and exam requirements going forward.
You can still buy the CASIO fx-CG50AU graphing calculator, as it remains a reliable model with 3D graphing, statistical analysis and a high-resolution colour display. It supports a wide range of functions required for senior mathematics and science subjects, including graphing multiple equations, running regressions, and working through calculus-based problems.
For students currently using this model or schools that still have it on their booklist, it continues to meet classroom and exam requirements. The interface is also familiar to many teachers, which helps maintain consistency in lessons and worked examples.
However, with the transition to the fx-1AU GRAPH, schools and students planning for future years may want to consider the newer model. This helps avoid needing to switch calculators mid-course and ensures alignment with updated booklists and teaching resources.
Yes! The emulator software for the CASIO fx-CG50AU graphing calculator is available for free through CASIO Education Australia. We provide this software for free through a program called Prime Schools Plus.

Yes. Many of the core functions and workflows are similar, so existing teaching materials, lesson structures, and worked examples can still be used. Topics such as graphing, statistics, and equation solving follow the same underlying processes, which helps maintain continuity in the classroom.
When transitioning to the fx-1AU GRAPH, CASIO provides updated resources and guidance to help teachers adapt existing content where needed. This includes videos, emulator support, and model-specific materials that highlight any differences in layout or functionality, making it easier to update lessons without needing to start from scratch.
