Which value represents the forecasted cost to complete the remaining work?

The value that represents the forecasted cost to complete the remaining work is indeed the Estimate to Complete (ETC). ETC is a critical concept in project management that provides an assessment of how much more money will be required to finish the project based on current project performance and the work that still needs to be completed.

This metric is particularly useful when evaluating how much budget is still left to achieve project milestones and deliverables. By using ETC, project managers can adjust their plans based on actual performance metrics and better manage remaining resources and finances.

In comparison, Earned Value (EV) is a measure of how much work has been completed in terms of budget. Actual Cost (AC) reflects the actual expenditures incurred for work completed to date, but does not give insight into future costs. Estimate at Completion (EAC) provides a total forecast of the cost at completion but combines the total costs incurred to date with the forecasted costs to complete, rather than just focusing on the remaining work. Therefore, ETC is the best choice for representing the specific forecasted costs to complete the remaining work.
