Can You Use Financial Calculator on CFA?

Official Eligibility Checker & Performance Estimator

Formula: Efficiency = (Approved Status * (1 – (1 / Practice Hours))) * Model Weight. Keystrokes are based on standard NPV/IRR/TVM inputs.

What is the CFA Institute Calculator Policy?

If you are wondering, can you use financial calculator on cfa, the answer is yes, but only for two specific models. The CFA Institute maintains a strict policy regarding the tools allowed in the examination room to ensure fairness and security. Only the Texas Instruments BA II Plus and the Hewlett Packard 12C are authorized. Any candidate attempting to use an unapproved device risks having their exam results voided and may face disciplinary action.

Who should use this guide? Every candidate—from Level I to Level III—must master one of these devices. A common misconception is that a scientific calculator or a phone app can suffice during study. However, because you cannot use those in the actual exam, practicing with the authorized models is vital for success.

can you use financial calculator on cfa: Formula and Mathematical Explanation

The “formula” for calculator success on the CFA exam isn’t just about knowing the TVM keys. It is about the relationship between keystroke efficiency and exam time management. The mathematical derivation of exam speed is:

Speed (Q/hr) = 3600 / (Reading Time + Thinking Time + (Keystrokes × Time Per Stroke))

Variable	Meaning	Unit	Typical Range
Model Approval	Binary status (0 or 1)	Boolean	1 (Authorized)
Time Per Stroke	Seconds per button press	Seconds	0.4 – 0.9s
TVM Memory	N, I/Y, PV, PMT, FV	Registers	5 slots
Cash Flow Depth	CF0 to CFn	Entries	20 – 80

Practical Examples (Real-World Use Cases)

Example 1: Calculating PV of a Bond

Suppose you are sitting for Level I. You need to find the price of a 5-year, 6% annual coupon bond with a market rate of 5%.
Inputs: N=5, I/Y=5, PMT=60, FV=1000.
Output: PV = -1,043.29.
In this case, can you use financial calculator on cfa to automate the discounted cash flow? Absolutely, and using the TI BA II Plus allows you to store these values and change only one variable (like I/Y) to see how the price fluctuates.

Example 2: IRR of an Unconventional Project

In Level II Corporate Finance, you might have cash flows of -$100, $30, $40, $50. Using the CF (Cash Flow) worksheet on the TI BA II Plus or the g-CFj function on the HP 12C, you can compute the IRR in seconds. Without an approved calculator, this would require iterative trial and error, which is impossible under exam time constraints.

How to Use This CFA Calculator Eligibility Tool

Follow these steps to determine if your device is ready for the exam:

1. Select your calculator model from the dropdown menu.
2. Choose your current CFA Exam Level to adjust the difficulty weight.
3. Enter the total hours you have spent practicing with the device. Experts recommend at least 100 hours of “muscle memory” training.
4. Review the “Eligibility Status”. If it says NOT AUTHORIZED, you must purchase a new device immediately.
5. Check the “Time Saved” metric to see how your current proficiency impacts your 3-hour exam window.

Key Factors That Affect Calculator Results

When considering can you use financial calculator on cfa, several technical and practical factors influence your performance:

• Entry Logic: TI uses algebraic entry (1+1=2), whereas HP 12C uses RPN (1 ENTER 1 +). RPN is often faster but has a steeper learning curve.
• Format Settings: You must set your calculator to at least 4 decimal places and use the “Chn” (Chain) or “AOS” calculation method depending on your preference.
• Reset Policies: Proctors will often ask you to reset your calculator memory before the exam starts. You must know how to re-configure your P/Y (Payments per Year) settings to 1.
• Battery Life: The TI BA II Plus Professional has a battery compartment that is easy to open. Ensure you have a fresh battery or a spare in your pocket (without the case).
• Keystroke Lag: Older HP 12C models might have a slight delay compared to the newer “Platinum” versions.
• Worksheet Proficiency: Mastery of the Bond, Depreciation, and Statistics worksheets can save 5-10 minutes on specific vignettes.

Frequently Asked Questions (FAQ)

Can I bring a backup calculator?

Yes, you can bring two approved calculators. Most candidates bring two TI BA II Plus units or one TI and one HP as a fail-safe.

What happens if my calculator is not on the list?

It will be confiscated by the proctor, and you will have to perform all calculations (including complex PV and IRR) by hand or using simple arithmetic, which is virtually impossible.

Do I need to clear the memory?

Yes. Proctors are trained to look for cleared memories. If you have formulas stored in “Data” or “Stat” worksheets, you may be flagged for a policy violation.

Is the TI BA II Plus Professional worth the extra cost?

Yes, it includes Net Future Value (NFV) and Discounted Payback, which the standard model lacks, saving valuable time in Level I and II.

Can I use a calculator cover?

No. Covers, cases, and instructional “cheat sheets” must be removed and stored in your locker or under your seat.

Does the HP 12C work for the CFA exam?

Yes, it is one of the two authorized models and is highly favored by older finance professionals for its durability and RPN logic.

Can I change the battery during the exam?

Yes, but you must bring the loose battery (no packaging) and your own small screwdriver if your model requires one (like the TI standard).

Is there a calculator provided at the test center?

No. Candidates must provide their own authorized financial calculator.
