Answer:
What is left at any instance of the project duration can be less than the budgeted sum? And if this is the situation then we need to calculate the over expense%, and which is:
oe%= ((Actual remaining *- Budgeted)/Budgeted)*100
And this gives us the amount by which the project is now lacking in the budget. However, project managers in the start itself assign some value for this, and hence this deficit does not create the problem at any time. And deficit occurs due to resources going down or falling ill. Or there can be an unwanted bug that requires more time.
