Calculation fields automatically total or average number values elsewhere in your form, so nobody has to do the math by hand. There are three types, each pulling from a different source: a standalone Number field, a Table column, or a List field.
Note: All three Calculation types only support two calculation methods: Addition and Average.
Calculation (Field)
Adds or averages values from individual Number fields elsewhere in your form. Use it when you want a quick total that isn't part of a List or Table, like combined hours from two separate Number fields.
Note: Create the Number fields you want to calculate first. Calculation (Field) only draws from standalone Number fields anywhere in the form; fields inside a List or Table won't appear as options here.
- Click New Field + inside the Group where you want your first number field.
- Select the Form Inputs tab.
- Click Number.
- Enter a Field Name (for example, Total Work Hours) and click Done.
- Repeat these steps for each additional Number field you want included in the calculation (for example, Total OT Hours).
- Click New Field + again.
- Select the Specialty tab.
- Click Calculation (Field).
- Enter a Field Name for the calculation.
- Choose a Calculation type: Addition or Average.
- In the Fields section, select which Number fields to include, then click Done.
Calculation (Table)
Totals or averages one column of numbers inside a Table field. Use it when you need a column total, like total hours across multiple rows of a timesheet table.
Note: Build the Table field with a Number column before adding this calculation.
- Click New Field + inside the Group where you want your table.
- Select the Specialty tab.
- Click Table.
- Enter a Field Name for the table.
- Select the Table tab, choose Number as a column type, and click + Add Column.
- Click New Field + again.
- Select the Specialty tab.
- Click Calculation (Table).
- Enter a Field Name for the calculation.
- Choose a Calculation type: Addition or Average.
- In the Table Fields section, select the column to calculate, then click Done.
Note: Calculation (Table) totals down a single column only. It cannot total values across a row. To total more than one column, add a separate Calculation (Table) field for each column, each pointed at a different column.
Calculation (List)
Totals or averages the values a user enters across every row of a List field. Use it when you want a running total for repeating entries, like total hours logged across multiple List rows.
Note: Calculation (List) only works when the field the List repeats is a Number field. See our Form Builder: List Field article for how to set that up.
- Click New Field + inside the Group where you want your list.
- Select the Specialty tab.
- Click List.
- Enter a Field Name for the list.
- Select the List tab, choose the Number field you want to repeat, and click Done.
- Click New Field + again.
- Select the Specialty tab.
- Click Calculation (List).
- Enter a Field Name for the calculation.
- Choose a Calculation type: Addition or Average.
- In the List Fields section, select the list field to calculate, then click Done.
Note: Calculation (List) updates live as users add or remove rows, so the total always reflects what's currently entered.
What Happens Next
Once published, the calculated field displays its result automatically as the person filling out the form enters values in the source Number field(s), Table column, or List rows. Calculation (List) recalculates immediately every time a row is added or removed, so the total always stays current.
Frequently Asked Questions
Can Calculation (Table) total values across a row instead of down a column?
No. Each Calculation (Table) field only calculates within a single column. There's currently no way to total values laterally across a row.
Can I add more than one Calculation (Table) field to the same table?
Yes. Add one Calculation (Table) field for each column you need to total, with each one pointed at a different column.
What number types can a Calculation field pull from?
Calculation (Field) draws from any standalone Number field in the form. Calculation (List) and Calculation (Table) only work with the Number field their linked List or Table column repeats.
Why isn't my field showing up as an option to calculate?
The field is probably not set as a Number type, or it lives inside a List or Table, which use Calculation (List) and Calculation (Table) instead of Calculation (Field).
What calculation methods are available?
Only Addition and Average. No other calculation methods are currently supported.
Does Calculation (List) update automatically as rows are added?
Yes. It recalculates live as rows are added or removed, so it always reflects the current entries.
