How to Use the BA II Plus Calculator Effectively for the CFA Exam

The CFA exam is renowned for its challenging calculations and complex financial concepts. The Texas Instruments BA II Plus calculator is a must-have tool for candidates tackling these problems. But are you using it to its full potential? This guide explores how to effectively use the BA II Plus calculator to save time and boost accuracy on exam day.

Why the BA II Plus Calculator Is Essential for the CFA Exam

The CFA Institute permits only two calculators: the BA II Plus and the HP 12C. The BA II Plus is the preferred choice for most candidates due to its intuitive design and advanced financial functions. Mastering this calculator can:

• Significantly reduce calculation time.

• Improve accuracy on complex problems.

• Build confidence for quantitative sections.

If you’re preparing for the CFA exam, knowing how to use the BA II Plus efficiently is non-negotiable.

Getting Started: Key Features of the BA II Plus

Before diving into advanced tips, let’s cover the basics of the BA II Plus calculator.

Key Functions:

• Time Value of Money (TVM): Essential for solving present and future value problems.

• Cash Flow Analysis: Useful for calculating Net Present Value (NPV) and Internal Rate of Return (IRR).

• Statistical Functions: Allows for mean, standard deviation, and regression calculations.

• Bond Valuation: Simplifies pricing and yield calculations for bonds.

• Depreciation Schedules: Supports various depreciation methods, including straight-line and declining balance.

Familiarize yourself with these features to maximize your efficiency during the exam.

Setting Up Your BA II Plus Calculator

Step 1: Reset Your Calculator

Before starting any calculation, reset your calculator to ensure it’s free of old settings or data.

Steps to Reset:

1. Press [2nd] + [RESET].

2. Press [ENTER].

3. The screen will display “RESET” to confirm.

Step 2: Set Decimal Places

The default setting shows two decimal places. For CFA calculations, set it to four decimal places for greater accuracy.

Steps to Adjust Decimal Places:

1. Press [2nd] + [FORMAT].

2. Enter “4” and press [ENTER].

3. Press [2nd] + [QUIT] to exit.

Step 3: Adjust the Payment Mode

Ensure the payment mode aligns with the problem’s requirements. The two modes are:

• END Mode: Default setting for most calculations.

• BGN Mode: Used for annuities due (payments at the beginning of periods).

To Switch Modes:

1. Press [2nd] + [BGN].

2. Press [2nd] + [SET].

3. Verify the display shows “BGN” for annuities due or nothing for END mode.

Time Value of Money (TVM) Applications

TVM is a cornerstone of the CFA curriculum. The BA II Plus simplifies these calculations with its dedicated TVM keys:

• N: Number of periods.

• I/Y: Interest rate per period.

• PV: Present value.

• PMT: Payment amount.

• FV: Future value.

Example: Calculating Future Value

Problem: Calculate the future value of $10,000 invested for five years at an annual interest rate of 6%.

Steps:

1. Press [2nd] + [CLR TVM] to clear previous inputs.

2. Enter “5” and press [N].

3. Enter “6” and press [I/Y].

4. Enter “10000” and press [PV].

5. Enter “0” and press [PMT] (no recurring payments).

6. Press [CPT] + [FV].

Result: The future value is $13,382.26.

Cash Flow Analysis for NPV and IRR

The BA II Plus simplifies cash flow-based calculations, which are critical for valuation and capital budgeting questions.

Example: Calculating NPV

Problem: Calculate the NPV of a project with the following cash flows and a discount rate of 8%:

• Year 0: -$100,000

• Year 1: $40,000

• Year 2: $50,000

• Year 3: $60,000

Steps:

1. Press [CF].

2. Enter “-100000” and press [ENTER], then [↓].

3. Enter “40000” and press [ENTER], then [↓].

4. Enter “50000” and press [ENTER], then [↓].

5. Enter “60000” and press [ENTER].

6. Press [NPV].

7. Enter “8” and press [ENTER].

8. Press [CPT].

Result: The NPV is $22,437.59.

Bond Valuation

Bond valuation is another key area where the BA II Plus shines. You can calculate price, yield, or coupon rate with ease.

Example: Calculating Bond Price

Problem: Calculate the price of a bond with:

• Par value: $1,000

• Coupon rate: 5%

• Time to maturity: 10 years

• Yield to maturity (YTM): 4%

Steps:

1. Press [2nd] + [CLR TVM].

2. Enter “10” and press [N].

3. Enter “4” and press [I/Y].

4. Enter “50” and press [PMT] (annual coupon: $1,000 × 5%).

5. Enter “1000” and press [FV] (par value).

6. Press [CPT] + [PV].

Result: The bond price is $1,081.11.

Statistical Functions

The BA II Plus’ statistical functions are invaluable for topics like regression analysis and standard deviation.

Example: Calculating Standard Deviation

Problem: Calculate the standard deviation of the following data set: {10, 12, 15, 18, 20}.

Steps:

1. Press [2nd] + [DATA].

2. Enter “10” and press [ENTER], then [↓].

3. Enter “12” and press [ENTER], then [↓].

4. Repeat for the remaining values.

5. Press [2nd] + [STAT].

6. Press [2nd] + [CPT] to calculate.

Result: The standard deviation is displayed.

Tips for Mastering the BA II Plus

1. Practice Regularly: Use the calculator daily to build muscle memory.

2. Memorize Key Shortcuts: For instance, [2nd] + [CLR TVM] clears TVM settings quickly.

3. Use Mock Exams: Simulate test conditions to practice solving problems efficiently.

4. Read the Manual: The BA II Plus manual provides detailed instructions and examples for advanced functions.

5. Double-Check Settings: Ensure the calculator is set to END mode unless otherwise specified.
