Custom number formula

The value of this read-only custom field is calculated automatically using a custom math or numeric expression.

You can use it to generate a number based on the values of other fields in the current work item or in related work items (such as linked issues, sub-tasks, epics, stories, or issues returned by a JQL query).

Create a custom number formula field

Choose the template

Just like for any other formula field, follow the steps outlined here: Create and configure formula fields and select the Custom number formula field template in the field creation assistant.

Once selected click on Next.

Provide the expression

Creating an expression from scratch might feel like a challenge, especially if you are not familiar with our expression editor (known from our app Jira Workflow Toolbox). But we have you covered!

Either start by looking at the built-in example expressions or browse through the use cases and examples we have collected for you at the bottom of this page.


Preview the output

Once you have provided the expression you can preview and validate the output by selecting an existing work item.

Number format pattern

If your formula field is being used to store a simple number (e.g. a dollar amount), you have the option to display the value just like you would expect it - by applying a custom Display formats.

You can even use emojis like 💵 💶 ⭐️ when selecting a custom format!
