What is a formula field?

A formula field is a field type that allows users to perform basic and advanced functions using different formulas. Using a formula field, you can create fields that are calculated instead of being entered by the user.

Formula Fields typically manipulate Number, Decimal and Date fields. The value of this field could be numeric or date depending on the output of the formula. In date manipulations, the result will be given in milliseconds, which you can format as per your requirement. Formula fields get recalculated automatically whenever the formula is changed. It also gets recalculated when a field involved in the formula is changed. Formula fields is same as any other custom field.
