Creating a Rollup Field

To create a Rollup field:

  • Under any list, click Fields
  • Click + Create New Field
  • Enter a field name
  • Select Rollup from the Field Type dropdown
  • Choose your referenced list
  • Continue with one of the methods below, depending on where your Linked List exists

Method 1 — Linked List Exists in the Target List

Use this method when your current list already has a Linked List field connected to the referenced list.

  • Select the referenced list
  • Choose the Linked List field in your current list
  • Select the field you want to calculate
  • Choose a Rollup type:
    • Sum — Total of all linked values
    • Average — Average of all linked values
    • Min — Lowest linked value
    • Max — Highest linked value
    • Count — Number of linked records with non-empty values

Method 2 — Linked List Exists Only in the Referenced List

Use this method when your current list does not have a Linked List field, but the referenced list links back to your current list.

  • Select the referenced list
  • Choose the Linked List field in the referenced list
  • Select the field you want to calculate
  • Choose a Rollup type: Sum, Average, Min, Max, or Count

Once you've completed these steps, your Rollup field will automatically calculate the selected value from the linked records.
