Common Misconceptions
Several common misunderstandings surround the CFA calculator policy. A frequent misconception is that “any non-programmable scientific calculator” is allowed. While non-programmability is a key factor, the CFA Institute specifically approves certain models. Another myth is that graphing calculators are universally banned; some older models might have been allowed historically, but the current policy is strict. Also, many candidates are unsure if their smartphone, tablet, or smartwatch can be used, which is explicitly forbidden. This calculator usage tool clarifies these points.
CFA Level 1 Calculator Policy: Rules and Explanation
The CFA Institute maintains a clear set of rules regarding calculators. The core principle is to permit only basic, non-programmable, non-advanced financial calculators that do not offer communication capabilities. Let’s break down the calculator policy details:
Allowed Calculators:
- Approved Financial Calculators: Texas Instruments BA II Plus (including BA II Plus Professional), and Hewlett Packard 10bII+ and 12c. Note that the HP 12c is an advanced financial calculator, but it is specifically permitted.
- Basic Scientific Calculators: Non-programmable scientific calculators are generally acceptable provided they meet the exclusion criteria.
Disallowed Calculators and Devices:
- Graphing Calculators: Most graphing calculators are prohibited.
- Programmable Calculators: Any calculator with programmable functions or text storage is forbidden.
- Communicating Devices: Calculators that can access the internet, communicate wirelessly (Bluetooth, Wi-Fi), or store extensive text/formulas beyond basic functions are not allowed. This includes smartphones, tablets, smartwatches, and computers.
- Dictation equipment, electronic dictionaries, or any device with a typewriter keyboard (QWERTY layout).
The policy aims to ensure that all candidates rely on their knowledge of financial concepts and basic calculation skills, rather than advanced computing power or stored information.
Formula and Mathematical Explanation
The “calculation” here isn’t a complex financial formula but a logical rule-based determination. We can represent the compliance logic as a series of conditions:
Compliance = (IsApprovedType OR IsBasicScientific) AND IsNonProgrammable AND IsNonCommunicating AND NOT HasQWERTY
Let’s define the variables used in the calculator:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Calculator Type | The category of the calculator being assessed (e.g., Approved Basic, Graphing, Smartphone). | Category | Predefined list |
| Programmable Memory/Text Storage | Indicates if the calculator can store user-defined programs or text. | Boolean (Yes/No) | Yes/No |
| QWERTY Keyboard | Indicates if the calculator features a full QWERTY keyboard layout. | Boolean (Yes/No) | Yes/No |
| Wireless Communication | Indicates if the calculator can connect wirelessly (Wi-Fi, Bluetooth) or access the internet. | Boolean (Yes/No) | Yes/No |
| IsApprovedType | Internal flag: True if the selected type is explicitly listed as approved by CFA Institute (TI BA II Plus series, HP 10bII+, HP 12c). | Boolean | True/False |
| IsBasicScientific | Internal flag: True if the selected type is a basic, non-programmable, non-graphing scientific calculator. | Boolean | True/False |
| IsNonProgrammable | Internal flag: True if the calculator does NOT have programmable memory or text storage. | Boolean | True/False |
| IsNonCommunicating | Internal flag: True if the calculator does NOT have wireless communication or internet access. | Boolean | True/False |
Calculator Logic Breakdown:
- Step 1: Type Check: First, the calculator’s type is assessed. Is it one of the explicitly approved models (TI BA II Plus series, HP 10bII+, HP 12c)? Or is it a general scientific calculator? If it’s a smartphone, tablet, or a known disallowed type (like most graphing calculators), it’s immediately flagged.
- Step 2: Feature Exclusion Check: Regardless of type, certain features automatically disqualify a calculator:
- Any form of programmable memory or text storage.
- A QWERTY keyboard.
- Wireless or internet communication capabilities.
- Step 3: Final Determination: A calculator is compliant ONLY IF it is either an explicitly approved model OR a basic scientific type, AND it lacks all disqualifying features (programmability, QWERTY, communication).
This systematic approach ensures adherence to the CFA Institute’s strict standards for examination integrity.

Familiarize yourself thoroughly with its functions, as you will not have access to external resources or advanced features during the test. This is a critical part of effective exam preparation.
Key Factors That Affect CFA Level 1 Calculator Compliance
Several factors determine whether a calculator is acceptable for the CFA Level 1 exam. Understanding these nuances is crucial for avoiding exam day disruptions. The CFA Institute’s policy is designed to level the playing field, ensuring that success hinges on financial knowledge, not technological advantage. Here are the key factors:
- Explicit Approval by CFA Institute: The most straightforward path to compliance is using a calculator explicitly listed on the CFA Institute’s approved list. Currently, these include the Texas Instruments BA II Plus (and its Professional version) and the Hewlett Packard 10bII+ and 12c. These models are vetted and known to meet the Institute’s requirements.
- Programmability and Memory Storage: This is a major disqualifier. Any calculator that allows users to store custom programs, formulas, or extensive text is strictly forbidden. The exam tests your understanding and ability to apply formulas, not to recall them from a stored database. Calculators with financial function keys (like NPV, IRR, PMT) are generally fine, but anything beyond that is suspect.
- QWERTY Keyboard Layout: Calculators or devices featuring a full QWERTY keyboard, similar to a typewriter or computer keyboard, are prohibited. This is because such keyboards can be used to input large amounts of data or text, which is not permitted. Standard numerical keypads and function keys are acceptable.
- Wireless Communication and Internet Access: Any calculator capable of transmitting or receiving data wirelessly (e.g., via Bluetooth, Wi-Fi) or accessing the internet is banned. This explicitly rules out smartphones, tablets, smartwatches, and any calculator with such integrated features. The exam environment is designed to be isolated from external data sources.
- Graphing Capabilities: While not all scientific calculators are disallowed, most graphing calculators are prohibited. These devices offer advanced visualization and computational power that goes beyond the scope of what is permitted for basic financial calculations required in the CFA Level 1 curriculum.
- Model Specificity vs. General Scientific Calculators: While the TI BA II Plus and HP 12c/10bII+ are specifically approved, the policy also allows for “basic scientific calculators.” However, the interpretation of “basic” is key. If a scientific calculator has any of the prohibited features (programmability, communication, QWERTY), it won’t qualify, even if it’s not a graphing model. Therefore, even with a “basic scientific” option, candidates must verify the absence of disqualifying features. Using a general scientific calculator requires careful scrutiny.
- Power Source: Although not a primary disqualifier for function, ensure your calculator uses batteries or solar power. Calculators requiring a mains electrical connection are obviously impractical and thus not relevant, but battery-powered devices must have reliable power. Ensure you have spare batteries if your approved calculator uses them.
- Text Display Capabilities: Calculators that can display more than a single line of text or equations might be scrutinized. While approved models can display formulas and inputs, devices designed for extensive text display are generally not permitted.
Thoroughly checking these factors against your specific calculator model is essential for a stress-free exam day. Always refer to the official CFA Institute calculator policy for the most current information.
