# How To Find Slope in Excel in 5 Steps (With Tips)

Updated June 24, 2022

Finding the slope of a line has many business applications, as it allows you to see the amount of change between two or more pieces of information. Excel is one program that allows you to calculate the slope of two or more points. If you want to find slope in Excel, it can help to understand the different methods and steps you can take. In this article, we explain how to find and calculate slope in Excel using either a function or scatter plot and some situations where you may need to find the slope.

## When is it important to find slope in Excel?

Finding slope is important when you want to find the rate of change between two or more points. You can use it in the workplace to determine performance over time, such as sales goals or overall productivity. You may also find a slope to compare the rate of change between two or more different things. For example, if you work for a chain restaurant, you can find the slope for profit increase at two stores to determine which location shows the most growth.

## How to find slope in Excel

These are the steps for using the slope function to find a slope in Excel:

To calculate slope, you need multiple points of data with two coordinates each. For example, if you want to calculate the slope of ice cream sales in the heat, collect information about how many ice cream cones you sell and the temperature outside. Gather your data onto a new or existing Excel sheet and organize it into two columns.

### 2. Determine X and Y values

A slope calculation has two coordinates to help map a data point on a chart. The Y value represents the vertical axis on a graph, while the X value represents the horizontal axis. Determine which column you want for your X and Y values so that you can use that information for your slope formula. For example, if you want to calculate the sales of a stuffed animal over time, you can call the number of sales your Y value and the months the animal is available to the public your X value.

### 3. Enter the formula

Choose a cell where you want to display the slope of your data and click on it. The formula for slope is "=SLOPE (known_ys,known_xs)," where known Y values and known X values stand for your columns of data. You can begin entering your formula by typing "=SLOPE(" and then adding your variables.

Once you have your formula started, you can enter your variables into your selected cell. Enter your Y value first to ensure the slope is calculated correctly. You can individually enter each piece of your data or use a colon to signify a range in a column. For example, if both columns have six numbers and your Y value is in column B, you can write the formula as "=SLOPE(B2:B7,A2:A7)".

### 5. Press the enter key

When you complete the formula, press your enter key to start the calculation. If you change your values in the columns, your formula can automatically re-calculate the slope. You can also edit the cells or columns the formula calculates by clicking on the slope cell and adjusting the information.

## Are there other ways to find slope in Excel?

While using the slope function is the main way to find slope in Excel, you can also calculate the slope by using a scatter chart. A scatter chart creates a graph of your data points and may work better for visual thinkers. Here are the steps for the scatter chart method:

### 1. Gather and organize your data

The scatter plot method uses the same data as the slope function method, so you can gather your information in the same way. Sort your data into X and Y values and two separate columns. Use your mouse to select both columns.

### 2. Create a scatter plot

Once you've selected both columns, click the "insert" button at the top of the page, and then click the "insert scatter" drop-down option. From there, select "scatter chart." This creates a scatter plot of your data.

### 3. Add a trend line

Choose a point on your scatter chart and right click on it. Select the "add trend line" option toward the bottom of the list. This makes a line that goes through the data points of your scatter chart.

### 4. Display equation

When you create a trend line, it also opens a format trend line window. In this window, you can select multiple options to help format your trend line. Check the box that says "display equation on chart" to see the slope of your trend line.

## Tips for finding slope in excel

These are some tips for finding slope in Excel:

The slope formula in Excel references existing data on your sheet to make its calculations. You can simplify the process by organizing your data in advance. Try to keep related data points together and sort them into columns so that you can provide a range for the formula instead of entering specific cells.

### Drag and drop

While you can manually enter a cell or range of cells when calculating slope, you can use the drag-and-drop method which can save you time. When writing your formula, you can select all of one column and drag it to your slope cell. This automatically provides the range of cells for your calculation.
