This post will guide you how to use the GROWTH function with syntax and examples in Microsoft excel.

Description

The Excel GROWTH function calculates the predicted exponential growth based on existing data. And it will return the y-values for a sets of new x-values that you specify by using one or more sets of existing x-values and y-values.

The GROWTH function is a build-in function in Microsoft Excel and it is categorized as a Statistical Function.

The GROWTH function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000, Excel 2011 for Mac.

Syntax

The syntax of the GROWTH function is as below:

= GROWTH (known_y's, [known_x's], [new_x's], [const])

Where the GROWTH function arguments are:

• Known_y’s -This is a required argument.  The known y-values that used to predict the exponential growth.
• Known_x’s -This is an optional argument.  The known x-values that used to predict the exponential growth. If this argument is omitted, and it will set as array {1,2,3…} by default.
• New_x’s – This is an optional argument. The new_x’s argument will be used to calculate the corresponding new y-values. If this argument is omitted, it will set as array {1,2,3…} by default.
• Const – This is an optional argument. A logical value specifying whether to force the constant b to equal 1.  And if Const is TRUE, the constant b is calculated normally. If Const is FALSE, the constant b is set to 1.

Note:

• If you want to return array result, then you need to the GROWTH formula as Array formula. When you create array formula, you need to press Ctrl + Shift + Enter on the formula box. And you will see that it will create brackets {} around your formula. You should know that if there is no brackets around your formula, it will not be treated as an array formula.

Excel GROWTH Function Examples

The below examples will show you how to use Excel GROWTH Function to calculate the predicted exponential growth based on a given set of y-values and one or more sets of x-values.

1# to calculate the predicted exponential growth, with known y-values B1:B4, with known x-values in A1:A4, , using the following array formula (you must be entered as an array formula via pressing Ctrl + Shift + Enter shortcuts):

{= GROWTH (B1:B4,A1:A4)}
