What is CFA Permitted Calculators?
The term cfa permitted calculators refers to the very specific set of electronic financial calculators authorized by the CFA Institute for use during the Chartered Financial Analyst exams. Unlike many other professional certifications, the CFA Institute maintains a strict policy: if your calculator is not on the list, you cannot bring it into the testing center.
Candidates often wonder why only two main brands are allowed. The reason is to ensure a level playing field for all candidates and to prevent the use of sophisticated programmable devices that could store text or advanced formulas. Whether you are taking Level I, II, or III, mastering one of the cfa permitted calculators is a non-negotiable part of your study journey.
CFA Permitted Calculators Formula and Mathematical Explanation
While the calculators themselves perform the math, understanding how “Mastery” is calculated in a study context is vital. Success is a function of keystroke speed and formula accuracy.
The Mastery Formula
In our calculator above, we use the following derivation:
Mastery (%) = (Practice Hours / (Target Hours × Complexity Multiplier)) × 100
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Practice Hours | Time spent using the calculator | Hours | 5 – 50 hours |
| Complexity | Difficulty of financial problems | Scale (1-10) | 3 (L1) – 9 (L3) |
| Target Hours | Base time needed for proficiency | Hours | 15 – 25 hours |
Practical Examples (Real-World Use Cases)
Example 1: Time Value of Money (TVM)
A candidate needs to find the Present Value (PV) of a $1,000 payment due in 5 years with a discount rate of 7%. Using cfa permitted calculators like the TI BA II Plus:
- Inputs: N=5, I/Y=7, FV=1000, PMT=0
- Output: CPT PV = -712.99
- Interpretation: You should pay no more than $712.99 today for that future cash flow.
Example 2: Net Present Value (NPV)
For a project with an initial outlay of $500 and cash flows of $200, $300, and $400 over three years at a 10% cost of capital:
- Inputs: CF0=-500, C01=200, C02=300, C03=400, I=10
- Output: NPV = 216.38
- Interpretation: The project adds value and should be accepted as the NPV is positive.
How to Use This CFA Permitted Calculators Tool
Maximizing your study efficiency requires knowing where you stand with your hardware. Follow these steps:
| Step | Action | Objective |
|---|---|---|
| 1 | Select your Model | Identify the specific logic (Algebraic vs RPN) you’ll use. |
| 2 | Input Practice Hours | Track your actual “hands-on” time with the device. |
| 3 | Set Complexity | Align the tool with your current CFA Level (I, II, or III). |
| 4 | Review Readiness | See your Mastery Score and Keystroke Efficiency Index. |
Key Factors That Affect CFA Permitted Calculators Results
Using cfa permitted calculators effectively depends on more than just pressing buttons. Several factors influence how accurate your results will be during the exam:
- Decimal Settings: By default, many calculators show only 2 decimals. CFA problems often require 4 or 9 for precision.
- Payment Mode (BGN vs END): Forgetting to switch between “Beginning of Period” and “End of Period” for annuities is a common source of error.
- Clear Work: Failure to clear previous registers (CLR TVM) can lead to data “bleeding” into new calculations.
- Battery Reliability: High-risk scenarios involve batteries dying mid-exam; always bring a spare or a second calculator.
- Notation Logic: Switching from a standard calculator to RPN on an HP 12C requires a complete shift in mathematical thinking.
- Reset Procedures: Knowing how to quickly reset your calculator to factory settings if it glitches during a high-pressure moment.
Frequently Asked Questions (FAQ)
1. Which are the only two cfa permitted calculators?
The only authorized brands are Texas Instruments (BA II Plus models) and Hewlett Packard (HP 12C models).
2. Can I bring a backup calculator to the exam?
Yes, you can bring multiple cfa permitted calculators into the testing room, provided they are both on the approved list.
3. Is the TI BA II Plus Professional worth the extra cost?
Yes, for many it is. It calculates Net Discount Payback and Modified Duration, which the standard model does not do as easily.
4. Can I use the HP 12C Platinum?
Absolutely. All versions of the HP 12C, including the Platinum and Anniversary editions, are cfa permitted calculators.
5. Do I need to show the proctor that I cleared my memory?
Proctors will inspect your calculator and may ask you to reset it or show that no unauthorized information is stored.
6. What happens if I bring a non-permitted calculator?
It will be confiscated, and you may face a disciplinary investigation by the CFA Institute, potentially leading to exam disqualification.
7. Does the TI BA II Plus have a “History” function?
No, these calculators are chosen specifically because they do not have multi-line history or text-storage capabilities.
8. Which calculator is faster for the exam?
The HP 12C using RPN is often considered faster for complex chains, but the TI BA II Plus is more intuitive for most students.
