### Cost Variance and Project Management Terms

If you’re looking to take the PMP exam, there are several definitions you need to know. You **MUST** know and understand the definitions listed in the table below.

The exam won’t come right out and ask you “What does Actual Cost mean?” The questions are more like: “What kind of Variance do you have on a deliverable if the Earned Value is $75,000 and the Actual Cost is $77,000?�

I won’t tell you the answer. I will, however, tell you how to figure it out.

**Cost Variance (CV) = Earned Value (EV) – Actual Cost (AC).
**A negative cost variance means you are over budget.

A positive cost variance means you are under budget.
