$40,000 (BCWP) – $20,000 (BCWS) = $20,000 (SV)
Your timetable variance right here is $20,000, which means that your mission is beforehand. To constitute this parent as a percentage, you could divide it with the aid of using the BCWS:
$20,000 (SV) ÷ $40,000 (BCWS) = 0.5
This means your mission is 50% beforehand.
