What is the Calculator Used for CFA Exam?
The calculator used for cfa exam refers specifically to the two authorized models permitted by the CFA Institute: the Texas Instruments BA II Plus (including the Professional version) and the Hewlett Packard 12c (including its Platinum, 25th anniversary, and 30th anniversary editions). No other calculators are allowed in the testing center, and using an unauthorized device results in immediate disqualification.
Candidates must master the calculator used for cfa exam because it performs complex financial computations like Time Value of Money (TVM), internal rate of return (IRR), and net present value (NPV) that are virtually impossible to solve manually within the strict time limits of the exam. Whether you are a Level I candidate or finishing Level III, your proficiency with these devices is a major determinant of your speed and accuracy.
One common misconception is that the “Professional” version of the TI BA II Plus is strictly required. While the Professional version offers additional functions like Modified Internal Rate of Return (MIRR) and Payback Period, the standard BA II Plus is sufficient for almost every calculator used for cfa exam requirement.
Calculator Used for CFA Exam Formula and Mathematical Explanation
The core logic within any calculator used for cfa exam centers on the Time Value of Money equation. This fundamental formula links five variables to find the unknown fifth variable based on the principles of compound interest.
The standard formula for Future Value (FV) is:
FV = PV * (1 + r)^n + PMT * [((1 + r)^n – 1) / r]
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| N | Number of Periods | Integer/Float | 1 to 360 |
| I/Y | Interest per Year | 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: Bond Pricing
An analyst needs to find the price of a 5-year bond with a 6% annual coupon and a 5% yield to maturity. Using the calculator used for cfa exam, the inputs would be: N=5, I/Y=5, PMT=60, FV=1000. Solving for PV yields 1,043.30. This demonstrates that when the yield is lower than the coupon rate, the bond trades at a premium.
Example 2: Retirement Savings
An individual wants to save $1,000,000 in 30 years with an expected return of 7% per year. Using the calculator used for cfa exam, we set FV=1,000,000, N=30, I/Y=7, and PV=0. Solving for PMT reveals an annual contribution of $10,586.40 is required to reach the goal.
How to Use This Calculator Used for CFA Exam
- Select Mode: Choose whether you want to calculate FV, PV, or PMT from the dropdown.
- Input N: Enter the number of years or compounding periods.
- Input Interest (I/Y): Enter the annual rate as a whole number (e.g., 8 for 8%).
- Enter Cash Flows: Provide values for the known variables. Remember that in the calculator used for cfa exam, one direction of cash flow (like an investment) must be negative, while the receipt is positive.
- Analyze Results: View the primary calculated result, the total interest earned, and the amortization table below.
Key Factors That Affect Calculator Used for CFA Exam Results
- Compounding Frequency: The calculator used for cfa exam defaults to annual (P/Y=1), but many problems require semi-annual or monthly compounding.
- Annuity Timing: Results differ significantly between “End” mode (ordinary annuity) and “Begin” mode (annuity due).
- Interest Rate Volatility: Even a 0.5% change in I/Y dramatically shifts PV and FV over long time horizons.
- Negative vs Positive Signs: Misentering the sign of PV or PMT is the number one cause of “Error 5” on the TI BA II Plus.
- Decimal Settings: Ensure your calculator used for cfa exam is set to at least 4 decimal places to avoid rounding errors in complex bond calculations.
- Clearing Memory: Always use the “CLR TVM” function before starting a new problem to clear previous stored values.

Frequently Asked Questions (FAQ)
Q: Which calculator used for cfa exam is better?
A: Most candidates prefer the TI BA II Plus because its algebraic entry is more intuitive than the HP 12c’s RPN logic.
Q: Can I bring two calculators to the exam?
A: Yes, you can bring two authorized models or extra batteries to the testing center.
Q: How do I change decimal places on the BA II Plus?
A: Press [2nd] [Format], type the number of decimals (e.g., 9), and press [Enter].
Q: What does “Error 5” mean?
A: It usually indicates a mathematical impossibility, often caused by having PV and FV with the same sign when they should be opposite.
Q: Should I use Begin or End mode?
A: Use “End” for most problems unless the question explicitly states “payments occur at the beginning of the period.”
Q: Is the HP 12c still relevant?
A: Yes, many finance professionals still swear by its build quality and speed once you master RPN.
Q: Do I need to clear my calculator used for cfa exam before the test?
A: Proctors will inspect and often reset your calculator to factory settings before the exam begins.
Q: How do I calculate NPV/IRR?
A: You must use the [CF] button to enter a list of cash flows, then press the [NPV] or [IRR] key to solve.
