CFA® Exam Approved Calculator Checker
Instantly verify if your calculator is one of the calculators permitted for use during CFA exams based on the official 2026 policy.
What Are the Calculators Permitted for Use During CFA Exams?
The CFA Institute enforces a very strict policy regarding calculators to ensure fairness and integrity during its examinations. Unlike many academic tests, you cannot bring just any financial calculator. Only two specific models are authorized. This policy on calculators permitted for use during CFA exams ensures no candidate has an unfair advantage through devices with advanced features like graphing or programming.
For the 2026 exams, the only two approved calculator models are:
- Texas Instruments BA II Plus (including the BA II Plus Professional model)
- Hewlett Packard 12C (including the HP 12C Platinum, 25th anniversary, 30th anniversary, and Prestige editions)
Any other calculator, regardless of its brand or capabilities, is strictly forbidden. Possession of an unauthorized calculator in the exam room will lead to the voiding of your exam results.
CFA Calculator Policy Explained
The “formula” for a permitted calculator is not about mathematical capability but adherence to the CFA Institute’s rules. The policy is designed to restrict functions that could store text, record keystrokes, or provide wireless communication. Our CFA study materials can help you master the functions of these approved calculators.
Permitted Model Specifications
The table below summarizes the only two calculator models you can bring into the testing center.
| Manufacturer | Model Name | Approved Variants |
|---|---|---|
| Texas Instruments | BA II Plus | Standard and Professional |
| Hewlett Packard | 12C | Classic, Platinum, Prestige, and Anniversary Editions |
Practical Examples
Understanding which calculators are not allowed is as important as knowing which are. Here are a couple of common scenarios.
Example 1: A Candidate with a Graphing Calculator
Input: A candidate selects “Texas Instruments TI-84 Plus” in the checker tool.
Result: NOT PERMITTED.
Reasoning: The TI-84 Plus is a graphing calculator. The CFA Institute policy explicitly forbids any calculator with graphing capabilities, as this could be used to store notes or formulas visually, providing an unfair advantage.
Example 2: A Candidate with an Approved Professional Model
Input: A candidate selects “Texas Instruments BA II Plus Professional” in the tool.
Result: PERMITTED.
Reasoning: The “Professional” version of the TI BA II Plus is explicitly listed as an approved variant in the official policy. It offers a few extra worksheet functions but is fundamentally compliant with the rules. Many candidates prefer it for its improved build quality. You can learn more with our CFA calculator guide.

Key Factors That Affect Calculator Eligibility
The CFA Institute’s decision to permit only two models is based on several key factors:
- No Graphing Capability: The calculator must not be able to display graphs.
- No Computer Algebra System (CAS): Devices that can solve algebraic equations are not allowed.
- No Text-Storage: Calculators with features that can store notes, formulas, or text are prohibited. A great way to prepare is to check our CFA Level 1 overview.
- No Wireless Communication: Any device with Bluetooth, Wi-Fi, or other data transfer capabilities is banned.
- Limited Programming: While the HP 12C allows for keystroke programming, its functionality is limited and well-understood, unlike modern programmable calculators.
- Established Standard: Both the TI BA II Plus and HP 12C have been the standard for decades, creating a level playing field.
Frequently Asked Questions (FAQ)
1. Can I bring two calculators to the CFA exam?
Yes, you are allowed to bring a backup calculator, but it must also be an approved model (either another BA II Plus or an HP 12C). You can even bring one of each.
2. Is the TI BA II Plus Professional version allowed?
Yes, the Texas Instruments BA II Plus Professional is explicitly permitted and is a popular choice among candidates.
3. Why can’t I use my university graphing calculator like a TI-84?
Graphing calculators are forbidden because their advanced functions, including data storage and graphing, violate the CFA Institute’s policy aimed at ensuring a fair testing environment.
4. What happens if I’m caught with a non-approved calculator?
Using or even possessing an unauthorized calculator will result in your exam results being voided and may lead to further disciplinary action.
5. Do I need to clear my calculator’s memory before the exam?
Yes, proctors may inspect your calculator and require you to show that the memory has been cleared. It is best practice to do this before you enter the testing room.
6. Are calculator instruction manuals or covers allowed?
Calculator covers and keystroke cards are permitted. However, instruction manuals are not allowed in the testing room.
7. Which calculator is better, the TI BA II Plus or the HP 12C?
The TI BA II Plus is generally considered more user-friendly and intuitive for new users as it uses a standard algebraic input method. The HP 12C uses Reverse Polish Notation (RPN), which can be faster for complex calculations once mastered but has a steeper learning curve. For more details, see our comparison of CFA calculators.
8. Will a calculator be provided at the test center?
No, you must bring your own approved calculator. None will be provided, and you cannot share with another candidate.
