# BETA.INV: Google Sheets formulas explained

As a digital marketer, spreadsheets are essential for organizing data and making calculations. Google Sheets is an excellent tool that allows you to collaborate with others, automate tasks, and visualize data in charts and graphs. However, to get the most out of Google Sheets, you need to know how to use formulas. In this article, I will explain BETA.INV, one of Google Sheets' many formulas, and show you how it can help you with financial analysis.
First, let me explain what a formula is. A formula is an equation that performs calculations on values in your spreadsheet. For example, if you want to calculate the average of a range of numbers, you can use the

AVERAGE formula. To use a formula in Sheets, you start by typing an equal sign (=) in a cell, followed by the name of the formula and the values or cell references you want to use.
BETA.INV is a statistical formula that calculates the inverse of the cumulative beta distribution function. I know that sounds complex, but bear with me. BETA.INV is used in financial analysis to calculate the expected return of an investment based on its volatility. Let's say you want to invest in two stocks, but you're not sure which one is less volatile. You can use BETA.INV to calculate the expected returns of each stock based on their volatility.
To use BETA.INV, you need to provide it with four arguments. The first argument is the probability of a return equal to or more than the expected return. Let's say you want to calculate the expected return for a 95% confidence interval. The probability you would use as the first argument would be 1-0.95, which is 0.05. The second argument is the alpha value of the beta distribution function. This can be found by dividing the expected return of the investment by its volatility and adding 1. The third argument is the beta value of the distribution function for the investment. Finally, the fourth argument is the lower bound of the distribution function.
Here's an example of how to use BETA.INV in Sheets. Let's say you want to invest in two stocks, and you have the following data:
Stock A expected return: 10%
Stock A volatility: 25%
Stock A beta: 0.5
Stock B expected return: 8%
Stock B volatility: 20%
Stock B beta: 0.4
First, you'll need to calculate the alpha values for each stock. For Stock A, the alpha value is (10%/25%) + 1 = 1.4. For Stock B, the alpha value is (8%/20%) + 1 = 1.4. Next, you'll need to calculate the expected return for a 95% confidence interval using BETA.INV. In cell A6, you can type =BETA.INV(0.05,1.4,0.5,0) to calculate the expected return for Stock A. In cell B6, you can type =BETA.INV(0.05,1.4,0.4,0) to calculate the expected return for Stock B. The expected returns for Stock A and Stock B are 14.47% and 12.67%, respectively.
Using BETA.INV in Sheets can save you time and improve the accuracy of your financial analysis. However, it's important to remember that formulas are only as good as the data you input. Always double-check your data to avoid errors in your calculations.
In conclusion, BETA.INV is a powerful tool that can help you make better investment decisions. By understanding how to use it in Sheets, you can calculate expected returns with greater accuracy and confidence. As a digital marketer, using statistical formulas like BETA.INV may not be a core skill, but it can set you apart when demonstrating your analytical capabilities.
