Formula: BCWP / BAC.
The formula for calculating PPI is straightforward and relies on two key metrics: Budgeted Cost of Work Performed (BCWP) and Budgeted Cost at Completion (BAC).
- BCWP:
BCWP represents the value of the work that has been completed on the project up to a specific point in time. It is calculated by multiplying the quantity of work completed by the budgeted cost per unit of work.
- BAC:
BAC represents the total budgeted cost of the entire project. It is the estimated cost of completing all the project activities as per the project plan.
- PPI Formula:
PPI is calculated by dividing BCWP by BAC and multiplying the result by 100. The formula is: PPI = (BCWP / BAC) * 100
- Interpretation:
The PPI value can range from 0% to 100%. A PPI of 100% indicates that the project is complete, while a PPI of less than 100% indicates that the project is still in progress.
By understanding the formula and its components, project managers can accurately calculate PPI and gain valuable insights into the project's progress and estimated completion date.
BCWP: Budgeted Cost of Work Performed.
Budgeted Cost of Work Performed (BCWP) is a crucial metric used in project management to measure the value of the work that has been completed on a project up to a specific point in time. It plays a vital role in calculating Planned Percent of Completion (PPI).
- Definition:
BCWP is the sum of the budgeted costs for all the activities that have been completed on the project, including both direct and indirect costs.
- Calculation:
BCWP is calculated by multiplying the quantity of work completed by the budgeted cost per unit of work. This calculation is performed for each activity in the project, and the results are then summed up to obtain the total BCWP.
