TREND Function in Excel
TREND function is a built on function in excel which comes under the category of Statistical function to calculate linear trend line of known y’s and know x’s. TREND function uses the “Least square method to find the line of best fit and to find new y-value for the given x-values. This function is used to predict the future based date where it will be very useful in accounting and financial reporting.
TREND Formula in Excel
The Formula for the TREND Function in Excel is as follows:
TREND Function uses the below arguments as follow:
Known_y’s: The known y’s is a range or array of y values from the line equation.
Known_x’s: The known x’s is a range or array of x values from the line equation. If this x value is null excel will assume those x_values as 1,2,3..with the same number of values as y values.
New_x ’s: The new_x’s represent the new_x value for which we need to trend to return corresponding values, if the new x argument is null (omitted)then it is considered as known_x’s value.
const: The const is a logical value that specifies either “TRUE” or “ FALSE”.

Note: The existing data needs to be linear data otherwise the output will be inaccurate.
Known_ Y-: This Known y_values is a dependent array or range of data.
Known_ X-: This Known x_values is an independent array or range of data.
New_X-: This new x value is used to return corresponding y values.
Const-: This const is a logical value i.e TRUE or FALSE.

How to use TREND function in excel?
TREND Function in Excel is very simple and easy to use. Let understand the working of TREND in Excel by Some Examples.
In this example, we have month wise sales data from Jan-18 to Sep-18 where we need to find the next month sales by using the TREND Function in Excel.
Using below TREND Formula.
Here the Trend function with the next month sales has been shown below.
So we have predicted the upcoming sales value for the next three months.
Let’s see another example with graphical chart format using multiple values.
The below example shows months wise sales data where there are ups and downs in sales value if we produce this format we cannot the view the sales data easily, Hence we can show the sales data in using trend function in chart format so that I will be given the appropriate result.
In the sales data B40 represents Month, C40 represents actual sales and D40 represent Trend values.
We are going to using the trend function here to get the result, select the column D41 to D56 and use the trend function as per below.
After selection uses the Trend function by selecting C41: C56 and then we have to use CTRL+SHIFT ENTER to get the entire trend value which is shown below.
To view in graphical chart format choose insert and select the line chart format.
So we get the line chart graph as given below where it shows very clearly sales data month wise.
Now this sales data shows only the trend figure with orange line show linear values and the graph will be more dynamic if we put the month wise growth value.
Use the growth function as explained above using CTRL+SHIFT+ENTER we will get a growth value figure with another line chart which is shown below in grey color.
In sales and financial accounting scenario, these charts are helpful to predict the company production and growth.
