## The calculated progress

The *calculated progress* is an indicator of the progress of a project, that is based on the progress of its tasks.

This value can be used by the project manager as a reference to set the *% completed* of the project or, alternatively, it can be directly set as the project’s progress by creating an automatic *progress report*.

The *calculated progress* is determined by the progress of its tasks, weighting **the duration** of each of them. In the formula, the following values are used:

- % completed of the tasks
- Duration of the tasks
- Duration of the project

The formula to calculate the calculated progress in a project with “n” tasks is:

*Calculated progress = % t1 * d1/D + % t2 * d1/D + % t2 * d1/D + … + % *tn* + *dn*/D*

- Being %tx : the completed percentage of the « x » task
- dx: the duration in days of the “x” task
- D: the duration in days of the project

Let’s see an example that clarifies the formula. In the following 20-day project, there are three tasks:

- Task 1, whose duration is 9 days with a 35% of completion
- Task 2, whose duration is 7 days with a 22% of completion
- Task 3, whose duration is 4 days with a 0% of completion

Therefore, the numbers will be:

*Progress calculated = 35%*9 days/20 days + 22%*7 days/20 days + 0%*4 days/20 days= 23%*
