They are as follows:

  • Formula 1. EAC = AC + Bottom-up ETC. This formula is used when the original estimation is fundamentally flawed. …
  • Formula 2. EAC =BAC/Cumulative CPI. …
  • Formula 3. EAC = AC + (BAC – EV) …
  • Formula 4. EAC = AC + [BAC – EV / (Cumulative CPI x Cumulative SPI)]

What is the formula for estimate at completion?

Estimate at completion (EAC) is calculated as budget at completion divided by cost performance index. Formula 1 for EAC is as follows: Estimate at completion (EAC) = Budget at completion (BAC) / Cost performance index (CPI)

Which two things would allow you to calculate a project cost estimate at completion?

In order to calculate the estimate at completion (EAC), you must know the budget at completion (BAC) and the cost performance index (CPI). With this information, the calculation is as simple as dividing the two.

How do you calculate EAC?

The formulas to calculate the EAC based on these 4 approaches are:

  1. EAC with bottom-up ETC: EAC = AC + ETC.
  2. EAC with ETC at budgeted rate: EAC = AC + BAC – EV.
  3. EAC with ETC based on present CPI: EAC = BAC / CPI.
  4. EAC considering CPI and SPI: EAC = AC + ((BAC-EV) / (CPI x SPI))

What is the best way to calculate the Estimate at completion EAC when original estimates are no longer valid?

They are as follows:

  1. Formula 1. EAC = AC + Bottom-up ETC. This formula is used when the original estimation is fundamentally flawed. …
  2. Formula 2. EAC =BAC/Cumulative CPI. …
  3. Formula 3. EAC = AC + (BAC – EV) …
  4. Formula 4. EAC = AC + [BAC – EV / (Cumulative CPI x Cumulative SPI)]

What is estimated cost completion?

Estimate at completion is the forecasted cost of the project, as the project progresses. There are a number of different ways to determine the EAC. The most common way to determine EAC is a “bottoms-up” formula where the actual costs (AC) are added to the forecasted remaining spending – the estimate to complete (ETC).

What is the difference between estimate to complete and estimate at completion?

Estimate at Completion is used for forecasting the amount of money at the end of the project. Estimate to Complete is the amount of money needed to finish the project at any point.

How do you calculate variance at completion?

VAC is calculated by subtracting the EAC from the BAC. Inturpreting the results is equally simple. If the VAC is a positive integer, that indicates the project is under budget. If the VAC is a negative integer that indicates the project will be over budget.
