Using FORECAST.LINEAR in Excel

Understanding FORECAST.LINEAR

The FORECAST.LINEAR function in Excel calculates a future y-value based on existing x-values and y-values through linear regression. Ideal for predicting sales, inventory, or trends, it's available in Excel 2016 and onward, replacing the older FORECAST function.

Step-by-Step Guide

Begin by organizing your known x-values and y-values in two separate columns. Select a cell where you want the predicted y-value for your new x-value to appear. Use the function by typing =FORECAST.LINEAR(argument1, argument2, argument3), where argument1 is the x-value for which you want to predict a y-value, argument2 is the range of known y-values, and argument3 is the range of known x-values. Press Enter to view the forecasted result.

Practical Application

Employ the FORECAST.LINEAR function to project future data points such as sales figures, inventory needs, or consumer behavior trends, leveraging Excel's analytical power to make data-driven decisions.

Transition from FORECAST to FORECAST.LINEAR

Users familiar with the older FORECAST function will find the syntax and usage of FORECAST.LINEAR identical. However, plan to transition to FORECAST.LINEAR as FORECAST will eventually be deprecated.

Common Use Cases

• 
  Predicting future sales based on historical data
• 
  Estimating inventory requirements for the upcoming quarter
• 
  Projecting the growth rate of a subscriber base
• 
  Analyzing trends in website traffic to allocate marketing budgets
