âWASBIRT-PCI is funded by the Substance Abuse and Mental Health Services Administration, Center for Substance Abuse Treatment SBIRT Grant (CFDA#93.243). The project is administered by the Washington Department of Social and Health Services and managed by the Division of Behavioral Health and Recovery.
1 CPI is computed by Earned Value / Actual Cost. 2  A value of above 1 means that the project is doing well against the budget. 3  Schedule Performance Index (SPI) : Represents how close actual work is being completed compared to the schedule. 4  SPI is computed by Earned Value / Planned Value. Cost Performance Index (CPI) : Represents the amount of work being completed on a project for every unit of cost spent. 2  CPI is computed by Earned Value / Actual Cost. 3  A value of above 1 means that the project is doing well against the budget.
Take a look at the table below to see how marginal cost was computed. For example, the marginal cost when the quantity is 56 is $2.82. This was computed by taking TC at 55.90Q ($350) minus TC at 38.16Q ($300) divided by 55.9Q minus 38.16Q (17.74Q).Take a look at the graph.n other words, the marginal cost is factored into the average total cost at every unit. Because of fixed cost, marginal cost almost always begins below average total cost. As quantity increases, ATC will decrease and MC will increase. Eventually they intersect, then MC continues to increase and pulls ATC up after it.
