Learn how to forecast with scenarios using what-if analysis tools in Excel

The Scenario Manager is a feature in what-if analysis and you can use this to enhance your forecasting in Microsoft® Excel®.

A scenario is a set of values that Excel saves and can automatically substitute in specific cells on a worksheet. You can create and save different groups of values on a worksheet, and then switch to any of these new scenarios to view results differently.

For example: Suppose you want to create a budget but you are uncertain of your revenue, you can define different possible values for the revenue and then switch between scenarios by applying any of the what-if analysis tools.
