Configure Estimate to Complete Calculation Settings

In Primavera Cloud, Estimate to Complete (ETC) is the remaining cost needed to finish the work for an activity, WBS, or the entire project, measured against the earned value baseline. Calculating ETC using Performance Factor (PF) helps project managers forecast the additional cost and units required to complete a project.

ETC calculation settings are applied at the project level to ensure that related cost estimates are all done in the same way. When you change the default calculation settings and edit values related to earned value, calculations automatically use the new setting to reflect your changes.

To configure ETC calculation settings for a project:

1. Navigate to the project settings page
   1. In the object selector, select Project.
   2. In the object selector, beside a project name, select , and then select View Summary & Settings.
   3. On the Summary & Settings page, select Settings.
2. On the Settings page, select the Earned Value tab.
3. In the Estimate to Complete section, select one of the following options to calculate ETC:
   • ETC = Remaining: (Default) Uses your current best estimate of what it will cost to finish the project, without recalculating from budget or performance. For example, if you estimate that $50,000 remains to finish paving, the ETC is $50,000.
   • ETC = PF* (Budget at Completion - Earned Value), where PF = 1: Extracts the unearned portion of the original budget (Budget at Completion − Earned Value). For example, if the foundation BAC is $100,000 and the EV is $40,000, then the ETC is $60,000.
   • ETC = PF* (Budget at Completion - Earned Value), where PF = 1 / Cost Performance Index: Scales the unearned budget by cost efficiency to date (CPI) so that the relative rate at which costs are incurred is taken into account. If the CPI < 1, ETC will be higher than the original budget, and if CPI > 1, ETC will be lower than the original budget. For example, if you are framing with a BAC of $100,000, an EV of $40,000, and the CPI is 0.8, then the ETC is calculated as [(100,000 − 40,000) / 0.8] = $75,000.
   • ETC = PF * (Budget at Completion - Earned Value), where PF = 1 / (Cost Performance Index * Schedule Performance Index): Adjusts the unearned budget for both cost and schedule efficiencies so that the relative rates at which costs are incurred and work is being completed on time are taken into account. For example, if a concrete pour has a BAC of $100,000, an EV of $40,000, the CPI is 0.8, and the SPI is 0.9, then the ETC is calculated as [(100,000 − 40,000) / (0.8 * 0.9)] = $83,333.

     Note You must recalculate current schedule costs after making changes to ETC calculation settings.
