ACWP is used in Earned Value Analysis

It is the Actual cumulative cost of doing work, and is usually compared to the cost planned in the Base programme (BCWS).

For a fuller understanding, this Wiki entry should be read in conjunction with BCWS and BCWP.

The total value of the activities are added up for each period and plotted cumulatively to give a profile on a graph.
