Cost Performance Index Notes:

Monitoring of a project is necessary. The difference between the planned work and the actual work is not a new thing. Also, the project can incur costs that are different from the estimated costs. The cost performance of a project is analyzed using different performance measures. One of the cost performance indicator is called cost performance index. It shows the cost efficiency with which a project is performed till that point. Cost performance index considers cumulative earned value and cumulative actual cost of a project or a work package in the calculation. The value of cost variance is calculated dividing cumulative earned value by cumulative actual cost. A cost performance index less than 1 shows that the value of actual work performed is less and smaller values of CPI need corrective action.
