| Cost performance index (CPI) | The ratio of budgeted costs to actual costs (BCWP/ACWP).
|
 |
|
|
| Cost variance (CV) | The difference between BCWP and ACWP (CV _ BCWP _ACWP). Tells if the work accomplished cost more or less than was planned at any point over the life of the project.
|
|
|
|
| Earned value (EV) | The physical work accomplished plus the authorized budget for this work. Previously this was called the budgeted cost of work performed (BCWP).
|
|
|
|
| Schedule variance (SV) | The difference between the planned dollar value of the work actually completed and the value of the work scheduled to be completed at a given point in time (SV _ BCWP _ BCWS). Schedule variance contains no critical path information.
|
|
|
|
| Time-phased budgets | Planned costs that are broken down by distinct time periods (e.g., $5,000 per week) for a work package, as opposed to a budget for a whole job/project (6 months for a total of $130,000). Time phasing allows better cost control by measuring the actual rate of expenditure versus the planned expenditure rate over small pieces of the project.
|
|
|
|
| Variance at completion (VAC) | Indicates expected actual cost over- or underrun at completion (VAC _ BAC _ EAC).
|
|
|
|
| Estimated cost at completion (EAC) | The sum of actual costs to date plus revised estimated costs for the work remaining in the WBS.
