How to Create a Summary Task in Microsoft Project

Use this interactive demo to learn how to group and indent tasks into a summary task in Microsoft Project.

Quick summary

A summary task in Microsoft Project groups related subtasks under a single parent task, giving project managers a rolled-up view of duration, cost, and progress. You create one by entering your tasks, selecting the subtasks, and using the Indent Task button on the Task tab.


Steps

  1. Open Microsoft Project and enter all the tasks that will belong under the summary task.
  2. Select the tasks that should be grouped together as subtasks.
  3. Go to the Task tab and click the Indent Task button to demote the selected tasks.
  4. The top task automatically becomes the summary task, and the indented tasks become its subtasks.

📌 Why this matters

Summary tasks in Microsoft Project are essential for organizing complex project schedules into manageable, hierarchical structures. By grouping related subtasks under a single parent task, project managers get an automatic roll-up of duration, cost, and completion percentage, eliminating manual calculations. This hierarchical view makes it easier to communicate high-level progress to stakeholders while maintaining detailed task tracking underneath. Teams that use summary tasks consistently report cleaner project plans and faster status reporting across large, multi-phase projects.
