Get the Estimate at Completion - Cost (EAC), i.e. the expected final cost of the project, at a given tracking period.

There are a variety of methods available to predict the final project cost given the current time and cost performance of a project in progress. Each method relies on another performance factor (PF) which refers to the assumption about the expected performance of the future work, as follows:

- PF = 1: Future performance is expected to follow the baseline schedule.
- PF = SPI or SPI(t): Future performance is expected to follow the current time performance.
- PF = CPI: Future performance is expected to follow the current cost performance.
- PF = SCI or SCI(t): Future performance is expected to follow the current time and cost performance. This method can be used under two versions, i.e. PF is equal to the current SCI performance or to a weighted time and cost performance.

Note that the methods using the current time performance as a performance factor can be used under the traditional Schedule Performance Index (SPI) assumptions, or with the new Earned Schedule based Schedule Performance Index (SPI(t)).

input | integer | ID | ID of the tracking period |

output | float | EAC_PF1 | EAC with PF = 1 |

output | float | EAC_PFCPI | EAC with PF = CPI |

output | float | EAC_PFSPI | EAC with PF = SPI |

output | float | EAC_PFSPIT | EAC with PF = SPI(t) |

output | float | EAC_PFSCI | EAC with PF = SCI with SCI = SPI x CPI |

output | float | EAC_PFSCIT | EAC with PF = SCI(t) with SCI = SPI(t) x CPI |

output | float | EAC_PFweightedSPICPI | EAC with PF = 0.2 x SPI + 0.8 x CPI |

output | float | EAC_PFweightedSPITCPI | EAC with PF = 0.2 x SPI(t) + 0.8 x CPI |
