What is a CFA Allowed Calculator?

A CFA allowed calculator refers to a specific type of electronic device that candidates are permitted to bring into the Chartered Financial Analyst (CFA) program examination rooms. The CFA Institute maintains a strict policy regarding the calculators that can be used during the exam to ensure fairness and prevent the use of unauthorized aids that could compromise the integrity of the testing process. The primary goal is to allow calculators that can perform essential financial computations without offering an unfair advantage through data storage, text retrieval, or advanced programming capabilities.

Who should use this information?

• CFA candidates preparing for Level I, Level II, or Level III exams.
• Individuals looking to purchase a new calculator for their CFA studies.
• Those who have inherited or borrowed a calculator and need to confirm its eligibility.

Common misconceptions about CFA allowed calculators include:

• Myth: Any scientific calculator is allowed. Reality: Only specific models from certain brands are approved.
• Myth: Programmable calculators are always forbidden. Reality: While most programming functions are banned, some calculators with limited, non-financial programmability may be allowed if they meet other criteria. However, it’s safest to stick to the universally approved list.
• Myth: All financial calculators are approved. Reality: The CFA Institute has a finite list of approved models; not all financial calculators meet their specific requirements or restrictions.

CFA Calculator Policy: Formula and Mathematical Explanation

The CFA Institute’s policy on allowed calculators is not based on a complex mathematical formula that calculates eligibility. Instead, it’s a rule-based system determined by the specific models that have been vetted and approved. Eligibility is primarily determined by checking if a calculator’s model number and brand appear on the official list maintained by the CFA Institute, and secondarily, if it possesses functions that are explicitly disallowed.

Core Criteria for Permitted Calculators:

1. Model Approval: The calculator model must be explicitly listed by the CFA Institute as permissible.
2. Non-Programmable: Calculators that can store text or formulas for later retrieval are generally disallowed.
3. Non-Alphabetic Keys: Calculators with alphabetic keys (like a full QWERTY keyboard) are not permitted.
4. No Network Connectivity: Devices that can connect to the internet or communicate wirelessly are forbidden.
5. No Power/Sound: Calculators that make noise or require AC power are not allowed.

The “formula” for eligibility can be simplified as a boolean check:

Eligibility = (Model on Approved List) AND (NOT (Contains Disallowed Functions))

Variable Explanations:

Calculator Eligibility Variables

Variable	Meaning	Unit	Typical Range/Values
Model on Approved List	Indicates if the calculator’s specific model is officially recognized and permitted by the CFA Institute.	Boolean (Yes/No)	Yes (e.g., BA II Plus, HP 12C) / No
Contains Disallowed Functions	Checks for features explicitly prohibited by the CFA Institute, such as text storage, advanced programming, alphabetic keyboards, or wireless communication.	Boolean (Yes/No)	Yes (e.g., Stores notes, has keyboard) / No
Functions Allowed	Confirms if the calculator has standard financial functions (like TVM, NPV, IRR) which are permissible, distinguishing it from basic scientific calculators without these features.	Categorical	Yes (Financial Functions) / No (Basic Scientific)

Practical Examples (Real-World Use Cases)

Example 1: Checking a Common Financial Calculator

Scenario: A candidate has a Texas Instruments BA II Plus Professional calculator and wants to confirm its eligibility for the CFA exam.

• Calculator Brand: Texas Instruments
• Calculator Model: BA II Plus Professional
• Advanced Functions Check: Yes (includes TVM, NPV, IRR, etc.)

Calculator Output:

Financial Interpretation: The Texas Instruments BA II Plus Professional is a widely recognized and approved calculator for the CFA exam. Its standard financial functions are essential for performing required calculations related to time value of money, net present value, and internal rate of return, making it a suitable choice.

Example 2: Checking a Basic Scientific Calculator

Scenario: A candidate is considering using a basic Casio fx-82MS scientific calculator.

• Calculator Brand: Casio
• Calculator Model: fx-82MS
• Advanced Functions Check: No (Primarily scientific, lacks dedicated financial functions like TVM)

Calculator Output:

Financial Interpretation: While the Casio fx-82MS is not on the CFA Institute’s specific list of approved financial calculators, it might be permissible if it’s a non-programmable scientific calculator that doesn’t contain disallowed features. However, candidates using such calculators will find it difficult or impossible to perform essential CFA exam calculations like TVM, NPV, and IRR efficiently, as these require dedicated financial functions. It is strongly recommended to use an approved financial calculator.

Example 3: Checking a Prohibited Calculator Type

Scenario: A candidate asks about using a smartphone app that mimics a financial calculator.

• Calculator Brand: Smartphone App (e.g., iOS Calculator App)
• Calculator Model: N/A (App-based)
• Advanced Functions Check: Yes (Potentially)

Calculator Output:

Financial Interpretation: Smartphone apps, graphing calculators with advanced programming capabilities, and any device with text retrieval or communication features are strictly forbidden during the CFA exam. Using such a device would lead to disqualification.

How to Use This CFA Allowed Calculators Tool

Navigating the CFA Institute’s calculator policy can be confusing. This tool simplifies the process. Follow these steps to determine if your calculator is eligible:

1. Identify Your Calculator: Find the exact brand name (e.g., Texas Instruments, Hewlett Packard, Casio) and the specific model number (e.g., BA II Plus, 12C Platinum, fx-991EX) printed on your calculator.
2. Enter Brand and Model: Type the identified brand and model into the respective input fields (“Calculator Brand” and “Calculator Model”). Be precise with spelling.
3. Assess Functionality: Select “Yes” for “Advanced Functions Check” if your calculator has built-in financial functions like Time Value of Money (TVM), Net Present Value (NPV), and Internal Rate of Return (IRR). Select “No” if it’s a basic scientific calculator lacking these dedicated financial computation keys or modes.
4. Check Eligibility: Click the “Check Eligibility” button.

How to Read the Results:

• Allowed: Your calculator is explicitly approved by the CFA Institute. You can confidently use it in the exam.
• Conditionally Allowed: Your calculator is not on the specific approved list but may be permitted if it meets the general criteria (non-programmable, no text storage, etc.). However, for efficient exam performance, it’s highly recommended to use an explicitly approved financial calculator.
• Not Allowed: Your calculator has features that violate the CFA Institute’s policy (e.g., programming, text storage, alphabetic keys, wireless connectivity) or is a prohibited device type (like a smartphone).

Decision-Making Guidance: If your calculator is marked as “Allowed,” you’re set. If it’s “Conditionally Allowed,” seriously consider purchasing an approved financial calculator. The time saved performing calculations with a dedicated financial calculator is invaluable during the high-pressure CFA exam environment. If it’s “Not Allowed,” you must obtain an approved model before exam day.

Key Factors That Affect CFA Calculator Eligibility and Use

Several factors determine whether a calculator is permitted for the CFA exam and how effectively you can use it. Understanding these is crucial for exam preparation:

1. CFA Institute’s Official List: This is the most critical factor. The Institute publishes a list of approved calculator models. Calculators not on this list are generally not allowed, with limited exceptions for basic scientific calculators.
2. Programmability: Calculators with the ability to store and execute user-written programs are forbidden. This prevents candidates from pre-loading formulas or complex algorithms.
3. Text Storage and Retrieval: Any calculator that can store text, formulas, or notes is prohibited. This includes calculators with QWERTY keyboards or extensive memory functions beyond basic data storage for calculations.
4. Financial Functions Availability: While not a barrier to entry, the presence of standard financial functions (TVM, NPV, IRR, cash flow analysis) is essential for efficient exam performance. Basic scientific calculators may be allowed but are impractical for CFA exams.
5. Alphabetic Keys: Calculators featuring keys that spell out letters (beyond basic function labels) are not permitted.
6. Connectivity and Sound: Devices with wireless communication capabilities (Bluetooth, Wi-Fi, cellular) or those that produce audible sounds are strictly prohibited.
7. Power Source: Calculators must be battery-powered. Those requiring AC power or having other complex power arrangements are disallowed.
8. Exam Level Specifics: While the core calculator policy remains consistent across Level I, II, and III, candidates should always refer to the latest guidelines provided by the CFA Institute for the specific exam year they are taking.

Financial Reasoning: The restrictions are designed to ensure that all candidates rely on their financial knowledge and computational skills, rather than on advanced technological aids. This maintains a level playing field and tests the candidate’s understanding of financial concepts and their application through manual calculation methods.
