PM% Complete Calculations

Davey,

Percent(%) Complete for a Project is calculated based on the following:

a) Total number of days scheduled duration.Sum of the number of days of Scheduled Duration of individual Tasks, including Tasks directly under the Project and the Tasks below its sub-projects(to any level).
b) Total number of days of work completed.For example, if a Task is estimated at 50 days of scheduled duration and 10% of it is completed, it is calculated as 5 days worth of work completed on that Task.

Example:
Consider the following Project hierarchy as an example:M1 (master project) -SP1 (sub-project) - 100 % complete ---T1 - duration 1 day - 100 % complete ---T2 - duration 1 day - 100 % complete -SP2 (sub-project) - 2% complete (by computing (7/354) * 100 ) ---T1 - duration 300 days - 0% complete ---T2 - duration 2 days - 100 % complete ---T3 - duration 2 days - 0% complete ---T4 - duration 50 days - 10% complete -SP3 (sub-project) - 0% complete ---T1 - duration 500 days - 0% complete ---T2 - duration 250 days - 0% complete Total duration of work in person-days = 1106Total work completed in person-days = 9 (100% of 1 day of effort + 100% of 1 day of effort + 100% of 2 days of effort + 10% of 50 days of effort)Therefore the total percent complete = ((9/1106)*100) = 0.81, which is rounded off as 0%.

In your example:

Total duration of work = 279.4 days (taken from task level)
Total work completed in person days = 159 + 4.05 = 163.05 days (See below)
Therefore the total % complete = (163.05 / 279.4)*100 = 58.35 = 58 % rounded

100% of 159 days = 159 days (taken from task level!)
27% of 15 days = 4.05 days work completed.
