Calculating Schedule and Cost Variance

Christopher Tangarife Linden, NJ, USA
I am currently studying for the CAPM and utilizing the PMI® Authorized On-Demand Certified Associate in Project Management (CAPM)® Exam Prep Course. 

In the prep course, specifically Module 8 section Project Controls and Forecasting/Earned Value Management page 7, it says the formula to calculate Schedule Variance is Schedule Variance = Earned Value (EV) - Actual Cost (AC).

While supplementing my study with other resources I see this formula is slightly different and what I see in all other resources is the following formula: Schedule Variance = Earned Value (EV) - Planned Value (PV)

Similarly for cost variance, the prep courses uses Cost Variance = Earned Value (EV) - Planned Value (PV). Other resources use CV = Earned Value (EV) – Actual Cost (AC).

I am currently following the PMI information first, but am curious about what others think is correct.

Christopher, this is surprising because I've always known SV = EV - PV and CV = EV - AC and I never heard otherwise. In previous versions of PMBOK, it was as is too.

Maybe it is a typo in the Exam Prep Course.

It is surprising. I default to the material in the prep course but after seeing the other formulas in other resources I figured it doesn’t hurt to reach out and get responses from seasoned professionals!

I just want to make sure I’m studying thoroughly and with the correct information

That definitely looks like an error in the courseware so if there is a point of contact for feedback provided, I would suggest submitting that.

I am surprised as such a glaring error should have been picked up as part of normal QC processes before the courseware was released.

We are happy to assist you with your question about the formula in your course "Cost Variance = Earned Value (EV) - Planned Value (PV)".

We reached out to our eLearning team for clarification. The formula listed within the course was reviewed and is correct as is."

Christopher, this is very odd and I doubt the formula is correct as is in the course. CV is always related to AC!

Recently, in many occasions, you contact customer care and you get 3 different answers from three different agents so I highly recommend you try again.

This speaks volumes about the caliber of folks PMI is hiring in Customer Care! If you contact them again and get the same response, you might direct their attention to the correct formulas in any number of PMI's standards and practice guides.
