To start creating a forecast sheet in Excel, ensure your data is time-based with two corresponding data series. This setup is crucial to predict future sales, consumer trends, and other developments.
Assemble your dataset with data at evenly spaced intervals. This step involves creating a time series dataset which is the foundation for the forecasting model.
With your dataset ready, select the cells containing the time-based series. Click the Data tab, then the Forecast Sheet button, found within the Forecast area. Fine-tune your forecast through the options provided, tailoring the start and end dates as necessary.
Once you click Create, Excel will generate a forecast for selected future dates. Default visual representation includes a line chart, showcasing historical and predicted values, with an additional option to use a bar graph for a different visual layout.
The forecast sheet includes 95% confidence interval limits to quantify the forecast's accuracy. This feature helps in assessing the reliability of the predictions made by the model.
For more fine-grained forecasts, use formulas like FORECAST or FORECAST.LINEAR, specifying the data point to be predicted (x argument) and the dependent (known_y's) and independent (known_x's) datasets.
Forecast sheets are instrumental in Excel for applications like forecasting payroll for student employees or creating complex monthly budgeting and forecasting models. Be aware of potential model errors, especially when rolling over forecasts.
