When you are setting up a project you can build a work breakdown structure to define the management elements of your project and give it some structure to manage. With the WBS you can also assign cost and revenue estimates that you can use to plan for your project. These can later be transferred to either or both the forecasts or budget.

This is a quick walkthrough where to setup these estimates.
