If your data series contains multiple values with the same date/time stamp, Excel averages the values with the same date/time stamp. The default value of “Interpolation” uses the weighted average of neighboring points to fill-in the value of missing points. You can use the “Fill Missing Points Using” drop-down to select “Zeros” to fill-in missing data points with zeros. The “Values Range” field contains the data values for the timeline values.įorecast Sheets in Excel – Instructions: A picture of a forecast sheet created in Excel. These are the time values that correspond to the data values in the “Values Range” field.

In the “Timeline Range” field, the range of timeline values appears. When manually setting seasonality, avoid using a value less than “2” to prevent the forecast from reverting to a linear trend. For example, in a yearly sales cycle where each data point plotted represents one month, “12” is the seasonality value. Then enter the seasonal value into the adjacent field. The default option is “Detect Automatically.” To manually set seasonality intervals, select the “Set Manually” option button.

To choose how to determine seasonal intervals, select a “Seasonality” option button. Alternatively, you can also type a new percentage to use into the box. If shown, the default confidence level of “95%” can be changed by using the adjacent spinner box. You can check or uncheck the “Confidence Interval” checkbox to show or hide the confidence interval in the forecast. For seasonal data, Excel recommends starting the forecast before the last historical point. If you pick a date before the end of the historical data, only data prior to the start date is used in the forecast. You can select a different forecast start date by using the “Forecast Start” drop-downs or spinner box to set the start date/time or starting value for the forecast. To set additional, advanced forecast options, click the “Options” arrow or link at the bottom of the dialog box to expand that section, if needed. Below the chart, use the “Forecast End” drop-downs or spinner box to set the end date/time or ending value and set how far out to project the forecast.įorecast Sheets in Excel – Instructions: A picture of the “Create Forecast Sheet” dialog box in Excel.

Doing this then displays the forecast as either a line chart or column chart. Choose either the “Create a line chart” or the “Create a column chart” button in the upper-right corner of the dialog box. Then click the “Forecast Sheet” button in the “Forecast” button group to open the “Create Forecast Worksheet” dialog box. To create the forecast sheet, either select both data series to forecast or click into a cell within one of the data series to forecast. However, you may want to summarize and organize the data before creating forecast sheets in Excel to produce the most accurate forecast. The timeline can have up to thirty percent of its data points missing or have duplicate time stamps on different values and still produce an accurate forecast. For example, you could have consistent daily, monthly, or yearly values for which to create a forecast. From these existing date or time values, Excel can then project future trends and the associated values for future dates.īefore you create forecast sheets in Excel, you should ensure your timeline’s values have consistent intervals between its data points. You must also have corresponding values for those time or date entries. To create forecast sheets in Excel, you must have a series of date or time entries for the timeline. You can insert forecast sheets in Excel into a workbook to predict future trends from existing time-based data.
