What are CFA Approved Calculators?
CFA approved calculators are the specific models of financial calculators permitted by the CFA Institute for use during the Chartered Financial Analyst (CFA) examinations. Unlike many professional exams that allow a broad range of devices, the CFA Institute maintains a strict policy to ensure fairness and prevent unauthorized data storage. Currently, only two models are allowed: the Texas Instruments BA II Plus (including the Professional version) and the Hewlett Packard 12C (including the Platinum and 25th/30th Anniversary editions).
Who should use these devices? Every candidate sitting for Level I, II, or III must master cfa approved calculators to solve complex Time Value of Money (TVM) problems, statistical analysis, and cash flow evaluations quickly. A common misconception is that one calculator is “better” than the other. In reality, the TI BA II Plus is more common among students due to its algebraic entry method, while the HP 12C is favored by older professionals who prefer Reverse Polish Notation (RPN).
CFA Approved Calculators Formula and Mathematical Explanation
The core of these cfa approved calculators is the TVM equation, which links five critical variables. The calculator essentially solves for one unknown when the other four are provided. The general formula for the future value of an ordinary annuity plus a lump sum is:
FV = -[PV × (1 + r)N + PMT × (((1 + r)N – 1) / r)]
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| N | Number of periods | Integer/Decimal | 1 to 360+ |
| I/Y | Interest rate per period | Percentage | 0% to 25% |
| PV | Present Value | Currency | Any |
| PMT | Periodic Payment | Currency | Any |
| FV | Future Value | Currency | Any |
Practical Examples (Real-World Use Cases)
Example 1: Retirement Savings
An analyst wants to know how much they will have in 20 years if they start with $10,000 and contribute $500 monthly at a 7% annual rate. Using cfa approved calculators, they would input: N=240, I/Y=7/12, PV=-10,000, PMT=-500. The FV result would show the total nest egg. The negative signs indicate outflows from the analyst’s pocket.
Example 2: Bond Pricing
To calculate the price of a 10-year, 5% semi-annual coupon bond with a market yield of 6%, a candidate using cfa approved calculators would set N=20, I/Y=3, PMT=25, FV=1000. Solving for PV would yield the current market price of the bond.
How to Use This CFA Approved Calculators Simulator
1. Select your Target: Use the “Solve For” dropdown to choose which TVM variable you need to find. This mimics the “CPT” (Compute) function on a TI calculator.
2. Input Data: Enter your known variables. Remember the sign convention used in cfa approved calculators: money leaving your pocket is negative, money coming in is positive.
3. Set Timing: Choose “End” for standard payments or “Begin” for payments made at the start of the period (Annuity Due).
4. Analyze Results: View the primary calculated value and the breakdown of interest versus principal in the dynamic results section.
Key Factors That Affect CFA Approved Calculators Results
- Compounding Frequency: Higher frequency (monthly vs annual) increases the effective yield.
- Sign Convention: Misplacing a negative sign is the #1 reason for “Error 5” or incorrect results on cfa approved calculators.
- Payment Timing: Annuity Due (Begin) results in higher PV/FV values because interest starts accruing immediately.
- Interest Rate Volatility: Even a 0.5% change in I/Y significantly impacts long-term FV due to compounding.
- Time Horizon: The power of N is exponential; longer periods drastically change the TVM landscape.
- Initial Capital: Higher PV amounts provide a larger base for interest to accumulate, magnifying PMT effects.
Frequently Asked Questions (FAQ)
Q: Can I bring a backup calculator to the exam?
A: Yes, you can bring multiple cfa approved calculators into the testing room as long as they are on the approved list.
Q: Does the calculator need to be cleared before the exam?
A: Proctors will check that your memory is cleared. Knowing the reset key sequence for your cfa approved calculators is essential.
Q: Why is my answer different from the textbook?
A: Check if your calculator is in “BGN” or “END” mode. Most CFA problems assume “END” unless stated otherwise.
Q: How do I handle semi-annual compounding?
A: Divide the annual I/Y by 2 and multiply the number of years by 2 before entering them into your cfa approved calculators.
Q: Which approved calculator is faster?
A: The TI BA II Plus Professional has slightly faster internal processing for IRR and NPV, but the difference is negligible for most questions.
Q: Can I use the HP 10bII+?
A: No. The HP 10bII+ is not one of the cfa approved calculators and will be confiscated by proctors.
Q: What happens if my battery dies?
A: You should change your battery before the exam or bring a spare. Proctors do not provide batteries.
Q: Do these calculators store text?
A: No, that is why they are cfa approved calculators. They lack the alphanumeric storage capabilities of graphing calculators.
