This document provides an overview of project cost management processes including developing cost baselines, earned value management, and variance analysis. It defines key terms like planned value, earned value, actual costs, cost variance, and schedule variance. Cost baselines include time-phased budgets for planned costs. Earned value management compares earned value to planned value and actual costs to calculate cost and schedule performance using indices like CPI, SPI, and variance. Variance analysis is used to track project performance and forecast final costs.

1. PMP COST FormulaE

2. Introduction:
o Project Cost Management is the knowledge use for managing
costs. It helps to ensure a project is completed within the
approved budget
o It includes the processes involving in estimating, budgeting and
controlling costs
o These processes interact with each other and with processes in
the other nine knowledge areas as well

3. Developing a Cost/Schedule System:
Define

phased

(PV)
o Compute the
schedule variance
(EV-PV) and the
cost variance (EV-
AC)

4. Cost Relationships Overview:

5. Development of Project Baselines:
Purposes of a Baseline
o It is an anchor point for measuring performance
o A planned cost and expected schedule against which actual cost and schedule are measured
o A summation of time-phased budgets (cost accounts as summed work packages) along a
project timeline
What Costs Are Included in Baselines?
o Labor, equipment, materials, project direct overhead costs (DOC)
Rules for Placing Costs in Baselines
o Costs are placed exactly as they are expected to be “earned” in order to track
them to their point of origin
o Percent Complete Rule
o Costs are periodically assigned to a baseline as units of work are completed over the duration
of a work package

6. o Project Manager can use the information about the
project progress to help control the schedule and
cost to assess whether the project is on track
through earned value management (EVM)
o EVM uses Variance Analysis methodology
o Other alternative methods are:
o Ask team members for a % of the work completed in each
work package or activity
o Team member provides a simple “guess” of work
performed
Earned Value Management (EVM):

7. Methods of Variance Analysis in EVM:
Comparing Earned Value
oWith the expected schedule value
oWith the actual costs
Assessing Status of a Project
oRequired data elements
o Budgeted cost of the work scheduled (PV)
o Budgeted cost of the work completed (EV)
o Actual cost of the work completed (AC)
oCalculate cost and schedule variances
o A positive variance indicates a desirable condition,
while a negative variance suggests problems or
changes that have taken place

8. oCost Variance (CV)
oIndicates if the work accomplished using labor
and materials costs more or less than was
planned at any point in the project
oSchedule Variance (SV)
oPresents an overall assessment in dollar terms
of the progress of all work packages in the
project scheduled to date

12. Cost Budget Components:

13. Terms:
EV Earned value for a task is simply the percent complete times its original budget. Stated differently, EV is the percent of the original
budget that has been earned by actual work completed.
PV The planned time-phased baseline of the value of the work scheduled. An approved cost estimate of the resources scheduled in a
time-phased cumulative baseline [BCWS—budgeted cost of the work scheduled].
AC Actual cost of the work completed. The sum of the costs incurred in accomplishing work. [ACWP—actual cost of the work
performed].
CV Cost variance is the difference between the earned value and the actual costs for the work completed to date where CV = EV – AC
SV Schedule variance is the difference between the earned value and the baseline line to date where SV = EV – PV
BAC Budgeted cost at completion. Total budgeted cost of the baseline or project cost accounts.
EAC Estimated costs at completion.
ETC Estimated costs to complete remaining work.
VAC Cost variance at completion. VAC indicates expected actual over- or under-run cost at completion.

14. Terms:
Performance Indexes:
• Cost Performance Index (CPI)
• Measures the cost efficiency of work accomplished to
date.
• CPI = EV/AC
• Scheduling Performance Index (SPI)
• Measures scheduling efficiency
• SPI = EV/PV
• Percent Complete Indexes
• Indicates how much of the work accomplished represents
of the total budgeted (BAC) and actual (AC) dollars to
date.
• PCIB = EV/BAC
• PCIC = AC/EAC

15. Terms:
Index Cost (CPI) Schedule (SPI)
>1.00 Under cost Ahead of schedule
=1.00 On cost On schedule
<1.00 Over cost Behind schedule

16. Cost /Schedule Graph:

17. Cost /Schedule Graphs: SV = EV -
PVCV = EV - AC

18. EV
Earned Value = EV
The value of the work
accomplished until this point
in time. Cost is as per the
original budget.
“ As of today, what is the
estimated value of the work
actually accomplished? “

19. PV
Planned Value = PV
Planned cost or value of the
work to be done until this
point in time.
“ As of today, what is the
estimated value of the work
planned to be done? “

20. AC
Actual Costs = AC
The costs actually incurred to
complete the work until this
point in time.
“ As of today, what is the
actual costs incurred for the
work accomplished? “

21. BAC
Budget At Completion =
BAC
The total planned value or
budget for completing the
entire project.
“ How much did we budget
for the total project? “

22. CV
Cost Variance = CV
CV = EV - AC
o Positive is Under Budget
o Negative is Over budget

23. SV
Schedule Variance = SV
SV = EV - PV
o Positive is ahead of
schedule
o Negative is behind
schedule

24. CPI
Cost Performance Index =
CPI
CPI =
o We are getting $___
worth out of every $1
spent.
o Greater than 1 is good;
less than 1 is bad
EV
AC

25. SPI
Schedule Performance
Index = SPI
SPI =
o We are progressing at
___% of the rate
originally planned.
o Greater than 1 is good;
less than 1 is bad
EV
PV

26. EAC
Estimate At Completion = EAC
Prediction of what project will
cost when completed..
“ What do we currently expect the
total project to cost (a forecast)?
“
There are 4 types:EAC = AC + Bottom up
ETC
BAC
CPI
EAC = AC + (BAC – EV)
EAC =
EAC =
(BAC – EV)
(CPI x SPI)
Used when the
original estimate
was flawed
Used when there are no variances
from BAC. Most common one for
exam
Used when the current
variances are “atypical” of
the future
Used when the current
variances are “typical” of the
future

27. ETC
Estimate To Complete = ETC
From this point on, How much
More do we expect it to cost to
finish the project ? (a Forecast)
How much more will the project
cost?
ETC = EAC - AC

28. VAC
Variance At Completion = VAC
As of today, how much over or
under budget will we be at the
end of the project ?
VAC = BAC -
EAC

29. TCPI
To Complete Performance
Index = TCPI
In order to stay within budget,
what rate must we meet for the
remaining work?
TCPI
=
(BAC – EV)
(BAC - AC)
o It divides the work remaining to be done
by the money remaining to do it
o Greater than 1 is bad; less than 1 is good
