EVMS Formulas

Question 1

Cost Variance (CV)

Answer 1

CV = BCWP - ACWP

Cost Variance = Budgeted Cost of Work Performed minus Actual Cost of Work Performed

Positive is favorable, negative is unfavorable

Question 2

CV %

Answer 2

Cost Variance Percentage

CV% = (CV/BCWP) * 100

CV% = (Cost Variance divided by Budgeted cost of work performed) times 100

CV % = ((BCWP-ACWP)/BCWP) * 100

Question 3

Schedule Variance (SV)

Answer 3

SV = BCWP - BCWS

Schedule Variance = Budgeted Cost of Work Performed minus Budgeted Cost of Work Scheduled

SV = (what we said we’d get done minus what we actually got done in hours/cost)

Question 4

SV %

Answer 4

SV % = (SV/BCWS) * 100

Schedule Variance Percentage = (Schedule Variance divided by Budgeted Cost of Work Scheduled) times 100

SV% = ((BCWP - BCWS) / BCWS) * 100

Question 5

Variance at Completion (VAC)

Answer 5

VAC = BAC - EAC

Variance at Completion = Budget at Completion minus Estimate at Completion

VAC = Baseline minus Forecast/current Status

Question 6

VAC %

Answer 6

VAC % = (VAC/BAC) * 100

Variance at Completion Percentage = (Variance At Completion divided by Budget At Completion) times 100

VAC % = ((BAC-EAC)/BAC) * 100

Question 7

Overall Percent Scheduled

Answer 7

% Scheduled = (BCWScum / BAC) *100

% Scheduled = (cumulative budgeted cost of work scheduled divided by Budget At completion) times 100

% Scheduled = (cumulative work scheduled now divided by baseline) times 100

Question 8

Overall Complete Percentage

Answer 8

% Complete = (BCWPcum / BAC) * 100

% Complete = (Cumulative budget cost of work performed divided by Budget At Completion) times 100

% Complete = (total work done now divided by baseline) * 100

Question 9

Overall Percent Spent

Answer 9

% Spent = (ACWPcum / BAC) * 100

% Spent = (cumulative actual cost of work performed divided by Budget At Completion) times 100

% Spent = ( Actual cost of work done now divided by baseline) * 100

Question 10

Cost Efficiency or Cost Performance Index (CPI)

Answer 10

CPI = BCWP / ACWP

Cost Performance Index = Budget Cost of Work Performed divided by Actual Cost of Work Performed

CPI = Baseline work / actual work done

Favorable is > 1.0
Unfavorable is < 1.0

Question 11

Schedule Efficiency or Schedule Performance Index (SPI)

Answer 11

SPI = BCWP / BCWS

Schedule Performance Index = Budgeted Cost of Work Performed divided by Budgeted Cost of Work Scheduled

SPI = Baseline / Forecast

Favorable is > 1.0
Unfavorable is < 1.0

Question 12

BEI - Baseline Execution Index

Answer 12

BEI = Total Tasks Complete / (Total tasks with Baseline Finish On or Prior to current Status/data Date + Tasks without baseline finish dates)

Question 13

Hit Task %

Answer 13

Hit Task % = 100 * (Tasks in denominator that completed On or Before baseline finish / Tasks baselined to finish within current status or data date reporting cycle)

Question 14

EAC

Estimate at Completion

Answer 14

EAC = Actuals to Date + (Remaining Work / Performance Index)

EAC CPI = ACWPcum + [(BAC - BCWPcum) / CPIcum]

EAC SPI = ACWPcum + [(BAC - BCWPcum) / SPIcum]

Question 15

EAC Composite

Answer 15

EACcomposite = ACWPcum + [(BAC - BCWPcum) / (CPIcum * SPIcum)]

Question 16

To Complete Performance Index - TCPI

Answer 16

TCPI target = Work remaining / cost remaining

TCPI target = (BAC-BCWPcum) / Target - ACWPcum)

 To Determine the TCPI for BAC, LRE, or EAC Substitute TARGET with BAC, LRE, or EAC
# To Determine the Contract Level TCPI for EAC, You May Replace BAC with TAB
