EVM Terms

Term Description Interpretation
PV Planned Value What is the estimated value of the work planned to be done?
EV Earned Value What is the estimated value of the work actually accomplished?
AC Actual Cost What is the actual cost incurred?
BAC Budget at Completion How much did you BUDGET for the TOTAL JOB?
EAC Estimate at Completion What do we currently expect the TOTAL project to cost?
ETC Estimate to Complete From this point on, how much MORE do we expect it to cost to finish the job?
VAC Variance at Completion How much over or under budget do we expect to be?

 

EVM Formulas

Name Formula Interpretation
CV (Cost Variance) EV – AC NEGATIVE is over budget, POSITIVE is under budget
SV (Schedule Variance) EV – PV NEGATIVE is behind schedule, POSITIVE is ahead of schedule
CPI (Cost Performance Index) EV / AC I am [only] getting _____ cents out of every $1.
SPI (Schedule Performance Index) EV / PV I am [only] progressing at ___% of the rate originally planned.
EAC (Estimate At Completion)   Note: There are a number of ways to calculate EAC. As of now how much do we expect the total project to cost $_____.
BAC / CPI Used if no variances from the BAC have occurred
AC + ETC Actual plus a new estimate for remaining work. Used when original estimate was fundamentally flawed.
AC + BAC – EV Actual to date plus remaining budget. Used when current variances are atypical.
AC + (BAC – EV) / CPI Actual to date plus remaining budget modified by performance. When current variances are typical.
ETC (Estimate To Complete) EAC – AC How much more will the project cost?
VAC (Variance At Completion) BAC – EAC How much over budget will we be at the end of the project?
