Your customer wants to calculate Estimate to Complete (ETC) as the difference between Current Planned Cost and Actual Cost. In Progress Settings…

The "Remaining Plan" Estimate to Complete (ETC) method calculates the remaining cost required to complete a project or task. The formula for this method is: ETC = Current Planned Cost - Actual Cost to Date. This directly matches the customer's requirement. By selecting "Remaining Plan" in the progress settings, the system will automatically derive the ETC based on the difference between the latest approved budget or forecast and the incurred actual costs, eliminating the need for manual calculations or effort-based estimations.

A. Effort: This method calculates ETC based on remaining planned effort (hours) multiplied by a rate, not directly from the difference between planned and actual costs.

B. Cost: "Cost" is a general term, not a specific ETC calculation method available in the progress settings. The question asks for the specific option to use.

C. Manual Entry: This option requires the project manager to manually input the ETC value, rather than having the system calculate it based on a formula.
