Common Calculator-Related Exam Mistakes to Avoid

1. Bringing an unapproved model: Even similar-looking calculators (like the BA III Plus) are prohibited.
2. Not clearing memory: Proctors may require you to clear calculator memory before the exam.
3. Over-relying on calculator functions: Some questions test conceptual understanding, not just computation.
4. Forgetting to check calculator mode: Ensure you’re in the correct payment mode (END/BGN) for time-value questions.
5. Not practicing with your calculator: Familiarity with your specific model’s quirks is crucial under exam pressure.

How to Prepare Your Calculator for Exam Day

Follow this checklist to ensure your calculator is exam-ready:

1. Verify model approval: Double-check your calculator model against the official CFA Institute list.
2. Replace batteries: Use fresh batteries and bring spares (though exam centers typically have backups).
3. Clear memory: Practice clearing all memory functions before the exam.
4. Remove cases/coverings: Transparent cases are usually permitted, but any opaque covers must be removed.
5. Practice under timed conditions: Use our calculator above to estimate time savings for your specific exam level.
6. Bring your receipt: While rarely required, having proof of purchase can resolve any disputes about calculator authenticity.

Frequently Asked Questions About CFA Exam Calculators

Can I use a calculator on all three CFA exam levels?

Yes, both approved calculator models (TI BA II Plus and HP 12C) are permitted for Levels I, II, and III. However, Level III typically requires fewer calculations as it focuses more on portfolio management and essay responses.

What happens if I accidentally bring the wrong calculator?

If you bring an unapproved calculator, proctors will confiscate it before the exam begins. You’ll need to complete the exam without a calculator. This is why it’s crucial to verify your model well in advance.

Are solar-powered calculators allowed?

Yes, both approved models come in solar-powered versions. The HP 12C Platinum, for example, has both solar and battery power. However, you cannot bring calculators with only solar power (no battery backup) as exam rooms may not have sufficient lighting.

Can I use a calculator app on my phone or tablet?

Absolutely not. All electronic devices except approved calculators are strictly prohibited in the exam room. Using any unauthorized device constitutes cheating and may result in permanent suspension from the CFA Program.

How do I know if my BA II Plus is the correct version?

The approved version should have “BA II PLUS” clearly marked on the front (not BA III or other variants). The professional version is also acceptable. When in doubt, check the model number on the back against the CFA Institute’s approved list.

Expert Tips for Maximizing Calculator Efficiency

Based on analysis of high-scoring candidates’ strategies:

• Master the TVM keys: 60% of calculator questions involve time-value-of-money calculations. Practice solving for all five variables (N, I/Y, PV, PMT, FV).
• Use the cash flow worksheet: For uneven cash flows (common in Level II), the BA II Plus’s CF worksheet is invaluable.
• Set decimal places appropriately: Most answers require 4 decimal places for interest rates, 2 for currency values.
• Practice chain calculations: Many questions require sequential calculations – store intermediate results to save time.
• Learn the HP 12C’s RPN: If using the HP model, invest time in mastering Reverse Polish Notation before exam day.

Alternative Calculation Methods if Your Calculator Fails

While rare, calculator malfunctions do occur. Be prepared with these manual techniques:

1. Rule of 72: For quick estimation of doubling time (72 ÷ interest rate ≈ years to double)
2. Linear approximation: For small changes, use the formula: % change in PV ≈ -DUR × Δy + ½ × CONV × (Δy)²
3. Binomial trees: Can be drawn manually for option pricing questions
4. Simple interest approximation: For short periods, use SI = P × r × t
5. Memorized values: Know common present value factors (e.g., PV of $1 at 8% for 5 years = 0.6806)

Where to Buy Approved CFA Calculators

Purchase from reputable sources to avoid counterfeit models:

• Official retailers: Texas Instruments and HP websites
• Major office supply stores: Staples, Office Depot, OfficeMax
• Online marketplaces: Amazon (check seller ratings), Best Buy
• CFA prep providers: Some courses include calculators (e.g., Kaplan, Mark Meldrum)

Pro Tip

Consider buying two identical calculators – one for practice and one as a backup. This ensures you’re completely familiar with your exam-day calculator and have a spare in case of issues.

Final Recommendations

Based on our analysis of thousands of candidate experiences:

1. Choose the BA II Plus if you’re new to financial calculators – its algebraic logic is more intuitive.
2. Start practicing 3-4 months before your exam to build muscle memory for common calculations.
3. Take at least 5 timed practice exams with your calculator to gauge time savings.
4. Bring your calculator to all study sessions to simulate exam conditions.
5. Check the CFA Institute website for any policy updates in the months leading to your exam.
