Given the following information for a one-year project, answer the following questions. Remember the following terms; planned value (PV), earned value (EV), actual cost (AC), and budget at completion (BAC).
PV = $44,000
EV = $53,000
AC = $45,000
BAC = $140,000
a). Use the formulas provided in Table 1, to determine the project’s cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?
Table 1: Earned Value Formulas
Term |
Formula |
Earned value |
EV = PV to date X% complete |
Cost variance |
CV = EV – AC |
Schedule variance |
SV = EV – PV |
Cost performance index |
CPI = EV / AC |
Schedule performance index |
SPI = EV / PV |
Estimate at completion (EAC) |
EAC = BAC / CPI |
Estimated time to complete |
Original time estimate / SPI |
Given, the inputs as follows:
PV = $44,000
EV = $53,000
AC = $45,000
BAC = $140,000
Cost Variance (CV) = EV - AC
= 53000 - 45000
= 8000
Schedule Variance (SV) = EV - PV
= 53000 - 44000
= 9000
Cost performance index (CPI) = EV/AC
= 53000/45000
= 1.178
Schedule Performance index (SPI) = EV/PV
= 53000/44000
= 1.2045
Cost variance | 8000 |
Schedule variance | 9000 |
Cost performance index | 1.178 |
Schedule performance index | 1.2045 |
