## What information do you need to calculate beta?

You need the following three pieces of information to calculate beta:

## Calculating beta using a formula

This is how you can calculate beta using a formula:

### 1. Type the formula

Click on the blank cell where you want to display your beta to get started. Since you can use two different formulas to arrive at the same number, you have choices. You can either start by typing “=COVARIANCE. P(” or “=SLOPE(. “.

### 2. Highlight the range with the stock returns

Click and drag from the top to the bottom of the cell range containing your stock returns without deselecting the box containing your formula. The cell range is automatically entered into the formula by Excel and appears as blue text. You can fill in the other variable once you’re certain you’ve highlighted the entire column range for the stock.

### 3. Select the range with the market returns

First, separate the two types of data by a comma. Once you’ve done that, you can highlight the range for the same date range as your stock returns that contains the market returns. This range in the “X variable” range is filled in automatically by Excel and appears in your formula as red text.

### 4. Enter the formula

Once the data in your formula has been successfully entered, you can complete the formula. For the “SLOPE=” option, close the formula with a parenthesis. For the “=COVARIANCE. P(” option, type “/VAR. P(” and then choose the market returns column to complete it once more before closing the formula in the same manner.

## Calculating beta using the analysis toolpak

You can also calculate beta using the “analysis toolpak” option by performing the following steps:

### 1. Install the analysis toolpak

Installing the analysis toolpak is simple if you don’t already have it. The “File” tab should be selected, followed by the “Options” and “Add-ins” categories. Click “Go” after selecting “Excel Add-ins” in the “Manage” box. Check the box next to “Analysis toolpak” in the “Add-ins” box, then click “Ok.” “.

### 2. Access the regression option

Install the “analysis toolpak,” then select “Data analysis” from the “Data” tab. Click “Ok” after selecting the “Regression” option from the pop-up menu. For the following step, you should concentrate on the “Input Y-range” and “Input X-range” key boxes. “.

Choose the range of cells that contain the returns for your target stock by clicking on the “Input Y-range” box. Excel automatically fills the range out in the box. The range of cells containing the market returns should then be highlighted after clicking the “Input X-range” box. Once both boxes have been filled out with data, click “Ok “.

### 4. Find the beta

Based on the data you enter, the “analysis toolpak” creates a fresh summary output spreadsheet. The number for beta calculation is in the “X variable” row and the “Coefficient” column among other numbers that you can use for various types of analysis. The number located there is your beta.
