Best For	Candidates new to financial calculators.	Finance professionals or those familiar with RPN.

A summary of the key differences between the two approved calculator families.

What is the CFA Calculator Policy?

The question of “can you use a calculator on CFA exams” is critical for every candidate. The CFA Institute enforces a very strict calculator policy to maintain a fair and standardized testing environment. This policy explicitly states that only two types of calculator models are permitted during the exam. Possession or use of any unauthorized calculator will result in the voiding of your exam results. The policy ensures that no candidate has an unfair advantage through devices with advanced features like graphing, internet access, or external data storage. Many candidates are surprised to learn that their advanced university calculator is not allowed, making it essential to verify their model well before exam day.

Common Misconceptions

A frequent misconception is that any “financial” calculator is acceptable. This is false. Only the specific models and their approved variations (like the “Professional” or “Platinum” versions) are permitted. Another common mistake is assuming a calculator app on a smartphone or watch is a viable backup. All smart devices are strictly prohibited. The core of the policy is not about the brand, but the exact approved model numbers. Understanding whether you can you use a calculator on CFA tests is the first step in proper exam preparation.

CFA Calculator Policy Rules and Logic

The “formula” for determining if you can you use a calculator on CFA exams is a simple logical check rather than a mathematical equation. The CFA Institute evaluates a calculator based on its model name. The logic is: IF the calculator model is a Texas Instruments BA II Plus (including the Professional version) OR a Hewlett Packard 12C (including its specified variations), THEN it is PERMITTED. Otherwise, it is NOT PERMITTED.

Variable	Meaning	Permitted Values	Typical Range
Manufacturer	The company that produces the calculator.	Texas Instruments, Hewlett Packard	Only these two are allowed.
Approved Model Family 1	The first series of approved calculators.	BA II Plus	Includes BA II Plus and BA II Plus Professional.
Approved Model Family 2	The second series of approved calculators.	12C	Includes 12C, 12C Platinum, and anniversary editions.
Prohibited Devices	Any device not on the approved list.	Graphing calculators, phones, smartwatches, etc.	All other devices are forbidden.

Practical Examples (Real-World Use Cases)

Example 1: Candidate with a TI BA II Plus Professional

A candidate preparing for the Level I exam owns a Texas Instruments BA II Plus Professional. They use our calculator checker and select “Texas Instruments BA II Plus Professional”. The tool immediately shows “PERMITTED”. This confirms they can you use a calculator on CFA test day without issue. They can now focus on mastering its functions for time value of money and cash flow analysis, confident their tool is compliant.

Example 2: Candidate with a TI-84 Plus

Another candidate, who used a TI-84 Plus graphing calculator throughout university, assumes it will be fine. They check our tool and select “Texas Instruments TI-84 Plus”. The result is “NOT PERMITTED”. This early check is crucial. It informs the candidate that they need to purchase one of the approved models and, more importantly, spend significant time practicing with it to be proficient by exam day. The query “can you use a calculator on CFA” is definitively answered, preventing a major issue at the test center.

Key Factors That Affect CFA Calculator Approval

While the decision seems binary, several factors feed into the central question of “can you use a calculator on CFA exams?” Understanding them helps clarify the policy.

• 1. Exact Model Number: This is the most critical factor. It’s not enough for it to be a “Texas Instruments financial calculator”; it must be the “BA II Plus” or “BA II Plus Professional”.
• 2. Approved Variations: The policy explicitly lists which variations are allowed, such as the HP 12C Platinum and its anniversary editions. No other variations are implicitly included.
• 3. Prohibited Features: The core reason for the strict policy is to ban calculators with features that could provide an unfair advantage, such as graphing capabilities, programmability beyond simple keystrokes, or any form of communication/data storage.
• 4. Physical Tampering: The calculator itself must not be tampered with. While you can change the batteries, the device should be in its original operating condition.
• 5. No Data Storage: Any device that can store text or extensive notes is prohibited. The approved calculators have limited memory registers for calculations only.
• 6. Official CFA Institute Policy List: The only list that matters is the one published by the CFA Institute. This policy is the ultimate source of truth, and our calculator is based on it.

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. Both will be inspected.

2. What happens if my calculator runs out of battery during the exam?

You are responsible for your equipment. You may bring a spare battery and a small screwdriver to change it, or simply use your approved backup calculator.

3. Is the TI BA II Plus Professional better than the standard BA II Plus?

The Professional version has a few extra functions (like discounted payback period) and a slightly better build quality. However, the standard model is sufficient for all three levels of the exam.

4. Why is the policy on “can you use a calculator on CFA” so strict?

To ensure fairness and a level playing field for all candidates worldwide, preventing anyone from using a device with stored notes, formulas, or graphing functions.

5. Do I need to clear my calculator’s memory before the exam?

Yes, proctors will likely inspect your calculator and may ask you to clear its memory to ensure no data is stored.

6. Can I use a calculator app on my phone or watch?

Absolutely not. All mobile phones, smartwatches, and other electronic devices are strictly prohibited in the testing room.

7. Which calculator is more popular among candidates?

The Texas Instruments BA II Plus is generally more popular, especially among new candidates, due to its intuitive algebraic entry system, which is similar to standard calculators.

8. Is the HP 12C’s RPN logic hard to learn?

Reverse Polish Notation (RPN) has a learning curve. However, users who master it often find it faster and more efficient for complex, multi-step financial calculations.
