## 2 Methods to Forecast Growth Rate in Excel

### 1. Forecast Growth Rate in Excel Using the GROWTH Function

We can use the **GROWTH function** to forecast any kind of growth rate in Excel.

The **GROWTH **function predicts an exponential growth rate which follows the formula below:

`y = b*m^x`

Here, the function will return a **“y”** value based on the **“x”** values.

**Function syntax:**

*GROWTH(known_y’s, [known_x’s], [new_x’s], [const])*

**Function Arguments:**

**Known_y’s:**This field is**mandatory**. Here you need to insert a set of past,**y**values according to the formula,**y = b*m^x.****Known_x’s: Optional**This is the set of past**x**values from the formula**y=b*m^x.****New_x’s:**This is**optional**Here you need to insert a new value of**x**for which you want to get the value of**y**.**const:**It’s also**optional**If const is**TRUE**,**b**is calculated normally. But if const is**FALSE**,**b**is set to 1. Thus,**y = b*m^x**becomes**y=m*x.**

#### 1.1 Forecast Sales Growth Rate in Excel

To **forecast the sales growth rate**, you will need historical time-based data. One date or time entry for creating the timeline and another column of their corresponding values.

I’m using a table of two columns for demonstration. The first column is the Year column that depicts the chronological timeline. The second column contains year-based corresponding sales in dollars.

Based on these data, we will predict the sales amount for the year 2014 in dollars.

Now,

❶ Click on cell **C14 **and insert the following formula:

`=GROWTH(C5:C13,B5:B13,B14)`

In the formula above,

**C5:C13**is the**Known_y’s.****B5:B13**is the**Known_x’s.****B14**is the

❷ After that hit the **ENTER **button.

Now we can predict the sales amount for the year 2014 will be $12,952.

#### 1.2 Forecast Revenue Growth Rate in Excel

We have a database of revenue growth rate in percentage from the year 2005 to 20013. Based on these data, we are going to **forecast the revenue growth rate** for the year 2014, 2015, and 2016.

To do that,

❶ Select cell **C14**, **C15**, and **C16 **to insert the following formula:

`=GROWTH(C5:C13,B5:B13,B14:B16)`

In the formula above,

**C5:C13**is the**Known_y’s.****B5:B13**is the**Known_x’s.****B14:B16**is the**New_x’s.**

❷ Now press **CTRL + SHIFT + ENTER** to insert the above formula as an array formula.

After executing the formula, we can see that the revenue growth in percentage has been forecasted. Which are 7.89%, 7.57%, and 7.27% respectively.
