Scenarios let you set up different... scenarios. This is useful when comparing different discrete options. For example, you might be trying to decide whether to hire 5 people or 10 people this year.

A scenario is a variant of your model in which some variables have different values or formulas. The structure of the model — the variables, groups, and sections — doesn't change across scenarios.

You can visualise multiple scenarios together in charts and tables, to easily compare them.

You can't perform calculations across scenarios. For example, you can't sum the values of a variable under different scenarios.

<aside> 📌 Best Practice: Scenarios vs Ranges We don't recommend using scenarios to account for things like "best-case" and "worst-case" versions of your model — this is what ranges are for**.**


Creating a scenario

There are 2 ways to create a scenario:

  1. Right-click on a cell and click New Scenario
  2. Click on Scenarios in the toolbar, and then click Add new scenario.

To rename a scenario, click on Scenarios in the toolbar, and double-click on the scenario name. To delete a scenario, hover over it and click the x button.

Scenario mode

To activate a scenario, click on Scenarios in the toolbar, and select the scenario.

This will take you into Scenario mode. In this mode, you'll be able to change the value of any variable, and this change will only be applied in the active scenario.

Variables that have been changed in a scenario will have a light blue background.

Visualising scenarios

By default, Charts and Tables will show the value of each variable under every scenario which affects it.
