In Dynamics CRM 2016, we can define attributes as Calculated and Rollup. Calculated fields allow a user to automate mathematical calculations used in the solution. Based on the type of the attribute, Dynamics CRM allows the user to configure an attribute with the type as Calculated or Rollup.

An attribute can be declared as a Calculated attribute if its value can be derived from a mathematical formula, such as the addition or multiplication of two fields.

An attribute can be declared as a Rollup field if its value can be derived using an aggregate function over a set of other records related to that specified record. For example, we can aggregate data from the activities related to the record, such as emails and appointments.
