epic progress/estimate does add up to 100%
Accepted answer
Here is the explanation regarding estimate % :
estimate % is the average of the plan items estimated % and the execution items estimated %
Estimate = ( [% plan items estimated] + [% execution items estimated] ) / 2
With 1 Estimated Story (plan item) and 1 non-estimated task (execution item):
plan items estimated % = 100 (1/1)
execution items estimated % = 50 (1/2) - the denominator here includes the story item as well
average = (100 + 50 ) / 2 = 75%
estimate % is the average of the plan items estimated % and the execution items estimated %
Estimate = ( [% plan items estimated] + [% execution items estimated] ) / 2
With 1 Estimated Story (plan item) and 1 non-estimated task (execution item):
plan items estimated % = 100 (1/1)
execution items estimated % = 50 (1/2) - the denominator here includes the story item as well
average = (100 + 50 ) / 2 = 75%
The question on why denominator in execution items % calculation is under debate but for now its included.
The top level plan item being considered in estimate calculation is something under discussion or rather a debate.

already exists. Though this is raised for Story work item, it applies to all top level plan items.
I would suggest you review this Enhancement and if you find it relevant, comment and continue discussions directly there.

Hi Marek Siekierski,
I have tried the above expression to get the estimated value on Epic. But i haven't successful on calculating the estimate in EPIC WI.
Please explain process to calculate estimated value in EPIC workitem using the below use case.
Use Case:
We have a stories under an epic, story has 5 tasks as a children, all tasks were estimated and has some time spent values as below.
- Epic (Progress - 0/5pts | 10/50hrs Estimated: 93% )
- Story 1 (Progress - 0/5pts | 10/50hrs Estimated: 100% ) and Status: In Progress
- Task 1 (Status: In Progress, Estimate - 10 h , time spent - 2 h )
- Task 2 (Status: In Progress, Estimate - 10 h , time spent - 2 h )
- Task 3 (Status: In Progress, Estimate - 10 h , time spent - 2 h )
- Task 4 (Status: In Progress, Estimate - 10 h , time spent - 2 h )
- Task 5 (Status: In Progress, Estimate - 10 h , time spent - 2 h )
We can see story has Estimated as 100%, but how EPIC workitem progress bar shows estimated as 93% ?
Thanks in advance.

Sep 12 '13, 12:42 p.m.Do any of the child work items have value in Time Spent ? I think that will dial back the overall estimates.
