How to use FORECAST function in Excel - formula exampleĪs already mentioned, the Excel FORECAST and FORECAST.LINEAR functions are purposed for linear trend forecasting.

If the variance of known_x's is zero, the #DIV/0! error occurs.

If the x value is non-numeric, the formula returns the #VALUE! error.

If the known_x's and known_y's ranges are of different lengths or empty, the #N/A! error occurs.

If your FORECAST formula returns an error, this is most likely because of the following reasons: The values of x̄ and ȳ are the sample means (averages) of the known x-values and y-values. How FORECAST and FORECAST.LINEAR calculate future valuesīoth functions calculate a future y-value by using the linear regression equation:Īnd the b coefficient (slope of the line) is: This function is available in Excel for Office 365, Excel 2019, and Excel 2016. The syntax of the FORECAST function is as follows: In other words, FORECAST projects a future value along a line of best fit based on historical data. The FORECAST function in Excel is used to predict a future value by using linear regression.

ETS.STAT - returns statistical values for time series forecasting.

ETS.SEASONALITY - calculates the length of a seasonal or other recurring pattern.

ETS.CONFINT - calculates the confidence interval.

ETS - predicts future values based on the exponential smoothing algorithm.

These functions are only available in Excel for Office 365, Excel 2019, and Excel 2016. The four ETS functions are purposed for exponential smoothing forecasts.

LINEAR - identical to the FORECAST function part of the new suite of forecasting functions in Excel 2016 and Excel 2019.

FORECAST - predicts future values by using linear regression a legacy function for backwards compatibility with Excel 2013 and earlier.

In the recent versions of Excel, there exist six different forecasting functions.
