Frequently Asked Questions (FAQ)
What is the formula for Cost Variance (CV) in EVM?
Cost Variance (CV) = Earned Value (EV) - Actual Cost (AC). A positive CV indicates an under-budget status.
What is the formula for Schedule Variance (SV) in EVM?
Schedule Variance (SV) = Earned Value (EV) - Planned Value (PV). A positive SV indicates an ahead-of-schedule status.
How is Cost Performance Index (CPI) calculated and interpreted?
CPI = EV / AC. A CPI > 1.0 means the project is performing under budget ($1.00 of EV earned for every $1.00 spent).
How is Schedule Performance Index (SPI) calculated and interpreted?
SPI = EV / PV. An SPI > 1.0 means project progress is ahead of schedule.
What is Estimate at Completion (EAC) using current CPI?
EAC = BAC / CPI, where BAC is Budget at Completion. This forecasts total final cost assuming current cost efficiency continues.
What is Estimate to Complete (ETC)?
ETC = EAC - AC, representing the remaining funds required to complete the project from the current date.
What is To-Complete Performance Index (TCPI)?
TCPI = (BAC - EV) / (BAC - AC). It measures the required cost efficiency needed on remaining work to stay within the original BAC.
What is Variance at Completion (VAC)?
VAC = BAC - EAC. A positive VAC forecasts a final cost surplus; a negative VAC forecasts an overall cost overrun.
Why does Schedule Variance (SV) become zero at project completion?
When all work is finished, EV equals PV (both equal BAC), causing SV = EV - PV = 0 regardless of whether the project finished late.
How is Earned Value measured on construction progress payments?
EV is calculated as Percent Complete × Task Budget (or verified bill of quantities installed value under AIA G702 / FIDIC Interim Payment Certificates).
