What are CFA Permitted Calculators?
The CFA Institute maintains a very strict policy regarding calculators allowed during exams. This policy ensures fairness and prevents any candidate from having an unfair advantage through devices with text-storage or communication capabilities. Only two specific models of business calculators are authorized for the CFA exams. Using or even possessing an unauthorized calculator in the testing room can result in the voiding of your exam results.
This tool helps you quickly verify if your model is one of the approved CFA permitted calculators. The policy is designed to level the playing field, so mastering one of the approved calculators is a key part of exam preparation.
Official List of Permitted Calculators
There is no complex formula for determining eligibility; it is a strict list-based policy. To be compliant, your calculator must be one of the models listed below. Note that certain variations and special editions are also permitted.
| Primary Model | Permitted Variations |
|---|---|
| Texas Instruments BA II Plus | Includes the standard BA II Plus and the BA II Plus Professional. |
| Hewlett Packard 12C | Includes the HP 12C Platinum, 12C Platinum 25th Anniversary Edition, 12C 30th Anniversary Edition, and HP 12C Prestige. |
Any calculator not on this list, such as graphing calculators (e.g., TI-84) or scientific calculators, is strictly forbidden. For more information, you can check our guide to the CFA exam study plan.

Key Factors of the CFA Calculator Policy
Understanding the reasoning behind the policy helps in appreciating its importance. Here are the key factors:
- Fairness: Ensures every candidate uses tools with the same core functionalities.
- No Unfair Advantage: Prohibits calculators with graphing, programming, or text-storing capabilities.
- Simplicity: Limiting the models simplifies the inspection process for proctors on exam day.
- Focus on Concepts: The exam is designed to test your understanding of finance concepts, not your ability to operate a complex calculator. The permitted models have all the necessary functions without being overly complex.
- Security: Restricting models prevents the potential use of devices with wireless communication features.
- Consistency: The policy has been consistent for many years, providing predictability for candidates preparing for the exams. For a deeper dive, review our financial modeling courses overview.
Frequently Asked Questions (FAQ)
1. Can I bring two calculators to the CFA exam?
Yes, you are allowed to bring a backup calculator, as long as it is also an approved model. Many candidates do this to be safe in case of a malfunction or battery failure.
2. What happens if I bring a non-permitted calculator?
It will be confiscated by the proctors before or during the exam. If you are found using one, your exam results will be voided.
3. Do I need to clear my calculator’s memory?
Yes, proctors will likely inspect your calculator and ask you to show that the memory has been cleared before the exam begins.
4. Which is the best calculator for the CFA exam?
The Texas Instruments BA II Plus (especially the Professional version) is generally more popular among candidates because its algebraic entry is more intuitive for most people. The HP 12C uses Reverse Polish Notation (RPN), which is powerful but has a steeper learning curve.
5. Are calculator instruction manuals allowed in the testing room?
No, instruction manuals are strictly prohibited. You are allowed to bring calculator covers, keystroke cards, and loose batteries.
6. Can I use a calculator app on my phone or tablet?
No. Mobile phones and all other electronic devices must be turned off and stored away. Using a calculator app is not allowed.
7. Where is the best place to get training on these calculators?
Many prep providers, including Kaplan Schweser and AnalystPrep, offer specific guides and video tutorials. You can also read our guide on top investment banking careers for context on how these skills are used.
8. Is the policy for CFA permitted calculators the same for all three levels?
Yes, the calculator policy is the same for Level I, Level II, and Level III of the CFA exam.
