BA II Plus Professional Investment Growth Calculator

This calculator simulates a core Time Value of Money (TVM) function of the Texas Instruments BA II Plus Professional financial calculator: calculating the future value of an investment with both an initial lump sum and regular periodic contributions. It helps you understand how your investments can grow over time, similar to how you'd use the N, I/Y, PV, PMT, and FV keys on the BA II Plus Professional.

Understanding the BA II Plus Professional and Investment Growth

The Texas Instruments BA II Plus Professional is a powerful financial calculator widely used by students and professionals in finance, accounting, and economics. It's renowned for its ability to quickly solve complex time value of money (TVM) problems, cash flow analysis, depreciation, bond calculations, and more.

Time Value of Money (TVM) Functions

At its core, the BA II Plus Professional excels at TVM calculations, which are fundamental to understanding how money grows or shrinks over time due to interest or growth rates. The calculator has dedicated keys for the five TVM variables:

• N (Number of Periods): The total number of compounding or payment periods.
• I/Y (Interest Rate per Year): The annual interest or growth rate. The calculator automatically adjusts this for the compounding frequency.
• PV (Present Value): The current value of a future sum of money or stream of cash flows. In our calculator, this is your "Initial Investment."
• PMT (Payment): The amount of each regular, periodic payment or contribution. In our calculator, this is your "Regular Contribution."
• FV (Future Value): The value of an asset or cash at a specified date in the future. This is the output of our calculator.

Our calculator above specifically focuses on solving for FV, given the other inputs, which is a common task for the BA II Plus Professional when planning for savings or investments.

How the Calculator Relates to the BA II Plus Professional

When using the BA II Plus Professional for a similar calculation, you would input values for N, I/Y, PV, and PMT, set the P/Y (Payments per Year) and C/Y (Compounding per Year) settings (which are often linked), and then compute FV. The "Payment Timing" (End of Period vs. Beginning of Period) corresponds to the calculator's "BGN" mode setting.

Example Calculation:

Let's say you make an initial investment of $10,000. You also plan to contribute $100 at the end of each month. Your investment is expected to grow at an annual rate of 7%, compounded monthly, for 10 years.

• Initial Investment (PV): $10,000
• Regular Contribution (PMT): $100
• Annual Growth Rate (I/Y): 7%
• Number of Years (N): 10
• Compounding/Payment Frequency: Monthly (12 times per year)
• Payment Timing: End of Period

Using the calculator above (or a BA II Plus Professional), you would find that the estimated future value of your investment after 10 years would be approximately $37,909.79.

This demonstrates the power of compounding and regular contributions, a concept easily explored with the BA II Plus Professional.
