The Cost Management includes the processes involved in estimating, budgeting, and controlling costs so that the project can be completed within the approved budget. Project managers must make sure that their projects are well defined, have accurate time and cost estimates, and have a realistic budget that they were involved in approving. Costs are usually measured in monetary units like dollars.

Before going to this knowledge area we need to familiar with some of the definitions or terms used in Cost management.


Profit = Revenue – Costs

Profit Margin = Profit / Revenue

Cash flow refers to the movement of cash into or out of the project.

Direct costs are costs that can be directly related to producing the deliverable of the project: salaries, cost of hardware & software purchased specifically for the project, etc.

Indirect costs are costs that are not directly related to the deliverable of the project, but are indirectly related to performing the project, e.g. cost of electricity, Internet, rent and office supplies.

Reserves are dollars included in a cost estimate to mitigate cost risk by allowing for future situations that are difficult to predict

Sunk cost is money that has been spent in the past; when deciding what projects to invest in or continue, you should not include sunk costs in the project budget.

  • To continue funding a failed project because a great deal of money has already been spent on it and it is not a valid way to include that money to the revised project budget to make a failed project successful, sunk costs should be forgotten

Variable Costs: change with the amount of production (cost of material).

Fixed Costs: do not change with production (rent, setup costs, etc.)

Net present value: the total present value (PV) of a time series of cash flows. It is a standard method for using the time value of money to appraise long-term projects. Higher the NPV is better.

Discount rate: Minimum acceptable rate of return on an investment.
