The basic syntax of the GROWTH function is:
=GROWTH(known_y's, [known_x's], [new_x's], [const])
Where:
known_y's: The set of y-values you already know in the relationship y = b*m^x.
known_x's (optional): The set of x-values you already know. If omitted, it assumes the x-values are 1, 2, 3, ...
new_x's (optional): The new x-values for which you want GROWTH to return corresponding y-values.
const (optional): A logical value specifying whether to force the constant b to equal 1.
Follow the steps below to use the GROWTH rate formula in Google Sheets.
Before using the GROWTH function, you'll need two sets of data: the known_y's and the known_x's. For our example, let's predict future sales based on past data:
Let's predict sales for the next 3 years (Years 5, 6, and 7).
In cell A6, enter 5 for year 5, A7 enter 6 for year 6, and in A8 enter 7 for year 7 as the new_x's values.
In cell B6, enter the GROWTH function as follows:
=GROWTH(B2:B5, A2:A5, A6:A8)
Press Enter.
Google Sheets will now display the predicted sales values for years 5, 6, and 7 based on the exponential growth curve fitted from the known data.
