Cheers guys, it seems that I need to use resource percent complete to allow the calculation to work correctly, weve not been using them here as it conflicts with forecasting our own ETCs. Im not sure theres a simple answer to what I want to achieve but at least I know now where the figures come from!

There are quite a few elements that influence the EVA calculation, so the best way is to go back step by step and determine where the numbers come from.
First you need to understand how the EV/BCWP is calculated in the specific WBS element you are rolling up your numbers in, since this can differ per WBS element. (with WBS milestones it totally ignores activty progress for instance)
Then you go back to the activity level and verify the BCWS, ACWP, and BCWP numbers. Check what baseline is used for BCWS calculation because this is often forgotten. This will allow you to understand how these number roll up and provide CVs and SVs at the WBS level.
Hope this helps,
Niek.

Performance % compl = (Earned Value Cost ) / (Budget at Completion) * 100.
You may want to check the Earned Value calculation tab on Admin Preferences, since EV can be calculated on budgeted or at completion values.
