Formula Builder
When creating a formula field for your object, create a field in Schema Manager and enable the Is Calculated toggle. This enables Formula Builder, a tool that allows you to create expressions to calculate the value of a field (for example, calculating the net price of a line item using the formula SalesPrice * Quantity).
Click Construct a formula here to open the Formula Builder, which allows you to create simple to complex expressions used to calculate field values for your object. All of the fields in the context object are available to use in the expression.
