How does progress percent and green bar length get calculated?

Pie displays a green bar across the project pie and its slices, and on top of process boxes. The length of the green bar represents percent done for that section. The precent number to the right of the project pie represents the total percent done for the project. The percent done on a Stack (group of projects such as a program) sums up the progress from its children projects.

All percent done progress is calculated by two things:

• Task progress state (check mark icon to the right of tasks)
• Task duration (days between start and due dates)

For example, let's say your project has two tasks, Task A has a duration of one day and Task B has a duration of ten days.

1. Task A - 1 day duration
2. Task B - 10 days duration

If you mark Task A is done (100% done where the check mark is completely green), then the project is 9% done. There's a total of 11 duration days and 1 divided by 11 is 0.09, or 9%.

Likewise, if Task A was not started and Task B was done, then the project would be at 91%. Again, there are 11 duration days and 10 are marked done, so 10 divided by 11 is 0.91.

The green bar length of a box or a slice represents only what's happening under that box or slices. Whereas, the precent number to the right of the project is based on all tasks, durations, and progress state across the project.

Formula:

Progress =
(sum of all tasks (task_duration * task_progress_in_percents)) / (sum of all tasks (task_duration))

• Process box progress is calculated only from tasks within the box.
• Slice progress is calculated only from only for tasks within the slice.
• Project progress is calculated from all tasks within the project.

Example:

Project has two tasks.

• Task A duration is 1 day and progress 100%.
• Task B duration is 10 days and progress is 0%.

(Task A duration of 1 is multiplied by 100%, making it 1.0) plus (Task B duration 10 is multiplied by 0%, making it 0). So, you have 1 + 0 = 1.

(Task A duration 1) plus (Task B duration 10). So, you have 1+10 = 11.

Now divide them, so you have 1 ÷ 11 = 0.091, or 9.1%
