While formula fields calculate values using fields within a single record, roll-up summary fields calculate values from a set of related records, such as those in a related list.

Because roll-up summary fields are not displayed on edit pages, you can use them in validation rules but not as the error location for your validation.

When to exclude records from roll up summary?
If your roll-up summary type is COUNT, records are included regardless of whether they contain a formula field with an error, but when the Field to Aggregate is a formula field that results in “#Error!”, calculations of type MIN, MAX, and SUM exclude those formula values.
