EVM formula

Budget at Completion (BAC)

Original budget of the project.

Planned Value (PV)

Amount of money worth of work we that should have been done on the project.

Earned Value (EV)

Amount of money worth of work you actually did on the project.

Actual Cost (AC)

Amount of money you already spend on the project

Cost Performance Index (CPI)

The rate of how we are spending to actually earning on the project.

Schedule Variance (SV)

The difference between the amount of work we should have done vs. the amount actually done.

Schedule Performance Index (SPI)

The rate of how we are meeting the project schedule.

Estimate at Completion (ETC)

Forecasting the total cost of the project at the end based on the current spending rate of the project.

Estimate to Completion

Forecasting the amount that will be needed to complete the current project based on the current performance.

Variance at Completion (ETC)

The difference between the original budget and new forecasted budget.

To Complete Perfomance Index (TCPI)

The performance that needs to be met to finish the project within the budget.

Planned Value (PV) formula

PV= Planned % Complete x BAC

Earned Value (EV) formula

EV= Actual % Complete x BAC

Cost Variance (CV) formula

CV = EV - AC

Cost Performance Index (CPI) formula

CPI = EV / AC

Schedule Variance (SV) formula

SV = EV - PV

Achedule Performance Index (SPI) formula

SPI = EV / PV

Estimate at Completion (EAC) formula

EAC = BAC / CPI

Estimate to Completion (ETC) formula

ETC = EAC - AC

Variance at Completion (VAC)

VAC = BAC - EAC

To Complete Performance Index (TCPI) formula

TCPI = (BAC – EV) / (BAC – AC)
