What is a CFA Approved Calculator?
A cfa approved calculator refers to the specific models of financial calculators permitted by the CFA Institute for use during the Chartered Financial Analyst (CFA) examinations. Unlike standard academic tests, the CFA Institute maintains a strict policy to ensure fairness and prevent candidates from using programmable devices that could store exam-related data.
Currently, only two primary families of calculators are authorized: the Texas Instruments BA II Plus (including the Professional version) and the Hewlett Packard 12C (including various anniversary editions). Candidates must master one of these devices, as the exam requires rapid calculations of net present value (NPV), internal rate of return (IRR), and complex time value of money (TVM) problems.
A common misconception is that one calculator is “better” than the other. In reality, the TI BA II Plus is preferred by those who like standard algebraic entry, while the HP 12C is a favorite for those accustomed to Reverse Polish Notation (RPN), often used in investment banking.
CFA Approved Calculator Formula and Mathematical Explanation
The core of a cfa approved calculator functionality lies in the Five-Key Time Value of Money (TVM) formula. This formula establishes the relationship between the five variables that define any financial transaction involving interest and time.
The fundamental equation solved by these calculators is:
| Variable | Meaning | CFA Key | Typical Range |
|---|---|---|---|
| N | Number of Compounding Periods | [N] | 1 to 360 (Months) |
| I/Y | Interest Rate per Period | [I/Y] | 0% to 25% |
| PV | Present Value (Current Worth) | [PV] | Variable |
| PMT | Annuity Payment Amount | [PMT] | Variable |
| FV | Future Value (Future Worth) | [FV] | Variable |
Practical Examples (Real-World Use Cases)
Example 1: Retiring with a Target Goal
A candidate wants to save $1,000,000 in 20 years. They have $50,000 currently and can earn 7% annually. Using a cfa approved calculator, we solve for PMT.
Inputs: N=20, I/Y=7, PV=-50,000, FV=1,000,000.
The result shows a required annual payment of approximately $20,325. This allows the candidate to understand the feasibility of their retirement plan using time value of money principles.
Example 2: Bond Valuation
Consider a 10-year bond with a 5% coupon rate (paid annually) and a par value of $1,000. If the market interest rate is 6%, what is the bond’s value?
Inputs: N=10, I/Y=6, PMT=50, FV=1,000.
The cfa approved calculator outputs a PV of -$926.40, indicating the bond should trade at a discount. Mastering these cfa calculator exam tips is vital for Level I candidates.
How to Use This CFA Approved Calculator
- Select Goal: Choose the variable you want to solve for (e.g., FV or PMT).
- Input PV: Enter the starting amount. Remember the sign convention: outflows (investments) are negative, inflows (receipts) are positive.
- Define Terms: Enter the number of periods (N) and the interest rate per period (I/Y).
- Set Timing: Choose between “End” (standard for most loans/bonds) or “Beginning” (common for leases).
- Analyze Results: The tool updates automatically, showing you the primary result and a breakdown of interest vs. principal.
Key Factors That Affect CFA Approved Calculator Results
- Compounding Frequency: Increasing the frequency (monthly vs. annually) significantly boosts future values due to interest-on-interest effects.
- Interest Rate Volatility: Even a 0.5% change in I/Y can result in massive swings in PV for long-dated assets like 30-year bonds.
- Time Horizon (N): The power of compounding is exponential. The longer the time, the more the interest component dominates the final result.
- Annuity Timing (BGN vs END): Payments made at the start of a period (Annuity Due) accrue interest for one extra period compared to end-of-period payments.
- Inflation Adjustments: While the calculator handles nominal rates, candidates must adjust inputs if they require real purchasing power results.
- Cash Flow Direction: Forgetting to toggle the sign of PV or PMT is the most common error on a cfa approved calculator, leading to “Error 5” or incorrect results.
Frequently Asked Questions (FAQ)
No, the TI-84 is not a cfa approved calculator. Only the TI BA II Plus and HP 12C models are permitted.
This usually occurs on a TI BA II Plus when there is no solution (e.g., trying to find the rate on an investment where all cash flows have the same sign).
The Professional model calculates additional metrics like Modified Duration and Discounted Payback, which can be helpful in Level II and Level III.
On a TI BA II Plus, press [2nd] [FORMAT], type “4”, and press [ENTER].
Speed is subjective, but the HP 12C’s RPN logic requires fewer keystrokes once mastered, though it has a steeper learning curve.
Yes, you may bring two cfa approved calculator devices as long as both are on the permitted list. It is recommended to bring a spare battery or a backup device.
BGN is for payments at the start of the period (like rent); END is for payments at the end (like most mortgage payments).
No, the cfa approved calculator models are non-programmable. You must memorize the logic for NPV, IRR, and TVM functions.
