# How Project Percent Complete is Calculated

There are many different variables that influence the calculation of "completion". Roadmap offers 3 automated calculations, in addition to manual tracking.

Go to Account Settings > Projects to choose among the 4 calculation methods.

### Weighted Percent Complete Methods

**Duration completed**is based on elapsed forecasted time and does not take into consideration whether or not the work item is completed. It is calculated at midnight.**Work completed**is based on elapsed forecasted time for completed work items. It is calculated in real-time.

Important Rules for Weighted Percent Complete Methods

- Resource assignments are optional
**BUT**estimates are required. - If no estimates exist, percent complete equals 0%. IF estimates exist, percent complete is based on work items with estimates. For example, if a project has 10 work items and only 1 work item has an estimate, percent complete is based on that 1 work item.
- Overall project-level forecasting is always calculated using duration completed method.

Below are some examples to compare and contrast duration- and work-completed methods.

### Simple Method

**Simple** looks at the number of completed milestones / to-dos vs. uncompleted. For example, suppose you have 3 milestones and 7 to-dos for a total of 10 work items. If 5 of work items are complete, the project is 50% complete.

### Manual Method

**Manual** allows users to drag-and-drop the % complete on the Project 360 page (A) or from the **Projects Tab > % Complete**
