CFA Allowed Calculators: Your Ultimate Guide & Comparison Tool

What are CFA Allowed Calculators?

For any candidate tackling the rigorous Chartered Financial Analyst (CFA) exams, understanding the rules around CFA allowed calculators is paramount. The CFA Institute strictly limits which calculators can be used during the exam. This isn't just a minor detail; bringing an unapproved calculator can lead to immediate disqualification. The approved models are specifically designed to perform complex financial and statistical calculations, which are essential for the exam curriculum.

This tool is designed for anyone preparing for CFA Level I, Level II, or Level III exams. It helps you confirm if your current calculator is approved, or assists you in choosing a new one that meets the requirements. Many candidates often misunderstand the exact models allowed or the specific features that differentiate them, leading to unnecessary stress or even exam day issues. Our guide clarifies these points, ensuring you're always using CFA allowed calculators.

Common misunderstandings often revolve around the distinction between the standard and professional versions of the Texas Instruments BA II Plus, or the specific HP 12c models. Additionally, candidates sometimes assume any "financial" calculator is permitted, which is incorrect. Only specific models are on the CFA Institute's approved list, and this tool focuses exclusively on these officially sanctioned CFA allowed calculators.

CFA Allowed Calculators: Models and Selection Logic

The CFA Institute currently permits only two basic models of financial calculators, though each has a slight variation. These are the Texas Instruments BA II Plus (including the BA II Plus Professional) and the Hewlett Packard 12c (including the HP 12c Platinum and HP 12c Platinum 25th Anniversary Edition). The selection logic for recommending a CFA allowed calculator boils down to matching candidate preferences and needs with the features of these approved models.

The "formula" for our calculator's recommendation is a logical decision tree:

IF (Specific Model Provided AND Is Approved) THEN Recommend Specific Model

ELSE IF (Brand Preference is TI OR RPN is NOT Preferred) THEN Recommend TI BA II Plus Professional (or standard if Professional not explicitly needed)

ELSE IF (Brand Preference is HP OR RPN IS Preferred) THEN Recommend HP 12c Platinum (or standard 12c)

ELSE (No Strong Preference) THEN Recommend TI BA II Plus Professional (due to broader user base and algebraic entry).

Practical Examples: Choosing Your CFA Allowed Calculators

Let's walk through a few scenarios to illustrate how to use this tool and select the ideal CFA allowed calculators for your needs.

Example 1: First-Time CFA Candidate, No RPN Experience

• Inputs:
  • CFA Exam Level: Level I
  • Desired Calculator Brand: Any Brand
  • Prefer RPN: No
  • Need Advanced Financial Functions: Yes (default)
  • Specific Model: (empty)
• Results: The tool would recommend the Texas Instruments BA II Plus Professional.
  • Explanation: For a new candidate without RPN experience, the algebraic input of the TI models is generally easier to learn. The Professional version offers slightly enhanced features like Net Future Value (NFV) and Modified Internal Rate of Return (MIRR), which can be useful and are fully allowed. This is a very common choice among CFA candidates.

Example 2: Experienced User, Prefers RPN

• Inputs:
  • CFA Exam Level: Level II
  • Desired Calculator Brand: HP
  • Prefer RPN: Yes
  • Need Advanced Financial Functions: Yes (default)
  • Specific Model: (empty)
• Results: The tool would recommend the HP 12c Platinum.
  • Explanation: If you're comfortable with or prefer RPN, the HP 12c series is an excellent choice. The Platinum version often has faster processing and more memory than the standard 12c. Its efficiency with RPN can be a significant advantage for those who master it, especially for complex bond calculations.

Example 3: Checking a Specific Model

• Inputs:
  • CFA Exam Level: Level III
  • Desired Calculator Brand: Any Brand
  • Prefer RPN: No
  • Need Advanced Financial Functions: Yes (default)
  • Specific Model: Casio fx-991EX
• Results: The tool would indicate: "Casio fx-991EX is NOT an approved CFA allowed calculator."
  • Explanation: This demonstrates the strict nature of the CFA Institute's policy. Even if a calculator is powerful, if it's not explicitly on the approved list (like the TI BA II Plus or HP 12c families), it cannot be used.

How to Use This CFA Allowed Calculators Tool

Our interactive tool simplifies the process of identifying and understanding CFA allowed calculators. Follow these steps to get your personalized recommendation:

1. Select Your CFA Exam Level: Choose from Level I, Level II, or Level III. While the approved calculators are the same across all levels, this helps us tailor context in our explanations.
2. Indicate Desired Calculator Brand: If you have a preference for Texas Instruments or Hewlett Packard, select it. If not, choose "Any Brand" for a broader recommendation.
3. Prefer RPN? (Checkbox): RPN (Reverse Polish Notation) is a distinct input method. If you're familiar with it or wish to learn it, check this box. Otherwise, leave it unchecked for algebraic-entry calculators.
4. Need Advanced Financial Functions? (Checkbox): All approved calculators handle core financial functions. Checking this ensures we recommend models that might offer slightly more advanced capabilities, though all CFA allowed calculators are sufficient.
5. Looking for a Specific Model? (Optional Text Input): If you already own a calculator or have a specific model in mind (e.g., "BA II Plus Professional"), type its name here to check its compatibility and get detailed information.
6. Click "Find Allowed Calculators": Once your preferences are set, hit this button to generate your recommendation.
7. Interpret Results: The tool will display a primary recommendation, key features, exam compatibility, and helpful notes. It will also explain the logic behind the recommendation.

Key Factors That Affect Your CFA Allowed Calculators Choice

While the list of CFA allowed calculators is short, several factors influence which one is the "best" for an individual candidate:

1. Prior Experience with Input Method: This is arguably the most significant factor. If you're used to algebraic entry (like most scientific calculators and the TI BA II Plus), switching to RPN (HP 12c) can be a steep learning curve. Conversely, RPN devotees find it incredibly efficient.
2. Learning Curve: The TI BA II Plus is generally considered easier to learn for beginners due to its algebraic input. The HP 12c, with RPN, requires more dedicated practice but can be faster once mastered.
3. Exam Level: While both types of CFA allowed calculators are sufficient for all three levels, some candidates find the advanced functions (like bond duration on the HP 12c or specific cash flow modifications on the BA II Plus Professional) more beneficial at Level II and III.
4. Budget: The standard versions (TI BA II Plus, HP 12c) are typically more affordable than their "Professional" or "Platinum" counterparts. All are well within a reasonable budget, but it's a consideration.
5. Specific Functionality: Both calculator families handle time value of money (TVM), cash flow analysis, and basic statistics. However, there are subtle differences. For example, the HP 12c is renowned for its bond functions, while the TI BA II Plus Professional offers Net Future Value (NFV) and Modified Internal Rate of Return (MIRR).
6. Ergonomics and Feel: This is subjective but important. Some prefer the button layout and tactile feel of one brand over the other. Since you'll be using it for hours, comfort matters.
7. Availability and Durability: Both brands are widely available. Consider build quality if you plan to use the same calculator for all three exam levels over several years.

Frequently Asked Questions About CFA Allowed Calculators

Q1: Can I use any financial calculator for the CFA exam?

A: No, absolutely not. The CFA Institute has a very strict list of CFA allowed calculators. Only specific models from Texas Instruments (BA II Plus, BA II Plus Professional) and Hewlett Packard (12c, 12c Platinum, 12c Platinum 25th Anniversary Edition) are permitted. Using any other calculator will result in immediate dismissal from the exam.

Q2: What is the difference between the BA II Plus and the BA II Plus Professional?

A: The BA II Plus Professional offers a few additional functions not found on the standard BA II Plus, such as Net Future Value (NFV), Modified Internal Rate of Return (MIRR), Modified Duration, and Payback Period. It also has a slightly more robust build quality. Both are fully approved CFA allowed calculators, and either is sufficient for the exam.

Q3: Is the HP 12c difficult to use because of RPN?

A: RPN (Reverse Polish Notation) is an input method that can feel counter-intuitive if you're used to algebraic entry. It requires practice to master, but many users find it highly efficient once they get the hang of it. If you're new to RPN, be prepared for a learning curve, but it's a powerful tool once mastered, and it's one of the approved CFA allowed calculators.

Q4: Can I bring two CFA allowed calculators to the exam?

A: Yes, the CFA Institute allows candidates to bring two approved calculators into the exam room. This is a highly recommended practice as it provides a backup in case one malfunctions during the exam, ensuring your focus remains on the questions.

Q5: Are there any other HP calculators allowed besides the 12c series?

A: No. Despite HP having other powerful financial calculators, only the HP 12c family (including Platinum versions) is explicitly listed as CFA allowed calculators. Do not assume other HP models are permitted.

Q6: Should I get the same calculator for all three CFA exam levels?

A: It is generally recommended to stick with one type of CFA allowed calculator throughout your entire CFA journey. This allows you to become highly proficient with its functions, saving valuable time during the exam. Switching calculators can introduce unnecessary errors and slow you down.

Q7: What if my calculator breaks during the exam?

A: This is precisely why bringing a second, fully charged and approved CFA allowed calculator is crucial. If your primary calculator fails, you can seamlessly switch to your backup without losing precious exam time or panicking.

Q8: Where can I buy CFA allowed calculators?

A: Both Texas Instruments BA II Plus models and HP 12c models are widely available at major electronics retailers, office supply stores, and online marketplaces like Amazon. Always ensure you are purchasing an authentic, new calculator to avoid issues.
