How to Calculate Money Weighted Return on Ba Ii Plus

Calculating money weighted return on a BA II Plus calculator involves determining the return on investments where each investment is weighted by its monetary value. This method provides a more accurate reflection of overall performance when investments vary significantly in size. This guide will walk you through the process, explain the formula, and provide practical examples.

What is Money Weighted Return?

Money weighted return is a financial metric that calculates the overall return on a portfolio of investments where each investment's contribution to the total return is proportional to its monetary value. Unlike simple average returns, money weighted returns account for the size of each investment, providing a more accurate representation of portfolio performance.

This method is particularly useful when investments vary significantly in size, as it ensures that larger investments have a proportionally greater impact on the overall return calculation.

Formula

The formula for money weighted return is:

Money Weighted Return = Σ (Investment Amount × Return) / Σ Investment Amount

Where:

Σ (Investment Amount × Return) = Sum of each investment's amount multiplied by its return
Σ Investment Amount = Sum of all investment amounts

Example Calculation

Consider two investments:

Investment A: $10,000 with a 5% return
Investment B: $20,000 with a 10% return

Using the formula:

Money Weighted Return = (($10,000 × 5%) + ($20,000 × 10%)) / ($10,000 + $20,000)

= ($500 + $2,000) / $30,000

= $2,500 / $30,000

= 8.33%

The money weighted return is 8.33%.

Interpretation

The money weighted return of 8.33% indicates that the overall performance of the portfolio is 8.33%, taking into account the size of each investment. This is higher than the simple average return of 7.5% (calculated as (5% + 10%) / 2), demonstrating the importance of considering investment sizes when evaluating portfolio performance.
