Calculation Field

A Calculation Field is used to display read-only values based on a calculation which may include values, from other fields on the form. This feature uses built-in functions to conduct operations against repeating data (date, number, text) to get subtotals or to aggregate data.


The label will display as the title of the field or the question that is being asked on the form. It is not recommended to leave the label blank because the label will be used as the column heading in Excel when form entries are exported.


Choose the type that describes the output of your calculation:

  • Text
  • Yes/No
  • Number
  • Percent
  • Currency
  • Date
  • Time


Click the lightening bolt icon to open up the advanced calculations editor. For more information about creating a calculation, see Calculations overview.

Help Text

Help text can be used to assist the user by providing additional instructions. Help text will display directly under the field.

Show This Field

By default, fields will always display on the form. However, you may want to hide specific fields or sections based on certain conditions such as a selected value of another field on the form.

  • Always - Field is always shown.
  • When - Field will only display when specific conditions are met. After selecting this option, the Conditional Logic Builder dialog will display allowing you to select when the field or section should be displayed.
  • Internally - Field will not display on the public form and will only display when a Cognito Forms user is editing the form from the Entries page.
  • Never - Field will never display.

Custom Error

You can set a custom error message that will display under your field when specified conditions become true. The conditional logic builder will allow you to add any number of rules for validating your field. Learn more about the custom error option.
