Standard CalculationThe standard calculation for Estimate To Complete is commonly given as:ETC = estimate at completion – actual costHowever, the standard calculation for Estimate at Completion is based on Estimate To Complete, meaning that the standard definitions are circular and not particularly useful.
Practical CalculationThere are two ways to calculate Estimate To Complete. The first is to generate new estimates for remaining work. In many cases, baseline project estimates are invalidated by cost overruns and new estimates are required. The second, is to use your original estimates adjusted by the percentage completion of your project tasks.
