What is Cost Management Plan


A cost management plan is a document that outlines the approach and strategies for managing costs throughout a project's lifecycle.

It is a part of the overall project management plan and guides how costs will be estimated, budgeted, monitored, and controlled.


Cost estimation

This section defines the methods and techniques that will be used to estimate the costs associated with the project.

It may involve breaking down the project into smaller tasks and estimating the costs for each activity.


The budgeting section outlines how the project's costs will be allocated across various resources and activities.

It includes the development of a detailed budget, which specifies the planned expenditures for labor, materials, equipment, and other project-related expenses.

Cost control

This part of the plan describes how the project's costs will be monitored and controlled to ensure they stay within the approved budget.

It outlines the processes and tools that will be used to track actual costs, compare them with planned costs, identify variations, and take corrective actions if necessary.

Change control procedures

Changes to the project scope, schedule, or other factors can impact costs.

The cost management plan should define the procedures for assessing and managing cost-related changes, including the evaluation of their impact on the project budget and approval processes.


The plan may outline the reporting requirements for cost-related information.

It specifies the frequency, format, and recipients of cost reports to ensure that project stakeholders are kept informed about the financial status of the project.

Roles and responsibilities

This section clarifies the roles and responsibilities of team members involved in cost management activities.

It identifies who is responsible for cost estimation, budgeting, monitoring, and control, ensuring accountability and coordination among project participants.


Budget control

A cost management plan helps to establish a baseline budget for the project.

It outlines the expected costs and helps in tracking and controlling actual expenditures against the budget.

By regularly monitoring costs and comparing them to the planned budget, the project team can identify any deviations and take corrective actions to keep the project financially on track.

Cost estimation accuracy

The cost management plan defines the methods and techniques for estimating project costs.

It ensures that cost estimates are based on reliable information and reasonable assumptions.

Accurate cost estimation helps in developing realistic budgets, setting appropriate financial targets, and avoiding surprises or overruns during the project execution.

Resource allocation

By having a cost management plan in place, project managers can effectively allocate resources based on the estimated costs.

It provides insights into the cost implications of different activities and helps in prioritizing and optimizing resource allocation.

This ensures that resources are utilized efficiently and effectively, avoiding unnecessary expenses or shortages.


A cost management plan provides decision-makers with valuable financial information.

It enables project stakeholders to evaluate the financial impact of various options or alternatives before making decisions.

For example, if a change request arises, the cost management plan helps in assessing the cost implications and determining whether it aligns with the project's budget and objectives.

Risk management

Costs are often associated with risks in a project.

A cost management plan helps in identifying, assessing, and managing cost-related risks.

By considering potential cost uncertainties and having contingency plans in place, the project team can mitigate risks and ensure that the project's financial health is safeguarded.

Stakeholder communication

A well-defined cost management plan provides a clear framework for communicating financial information to stakeholders.

It ensures that stakeholders are kept informed about the project's financial status, including planned and actual costs, budget performance, and any cost-related issues or changes.

This transparent communication helps in building trust and maintaining stakeholder support throughout the project.


Plan development

Begin by creating a comprehensive cost management plan.

It involves identifying the key components mentioned earlier, such as cost estimation, budgeting, cost control processes, change control procedures, reporting requirements, and roles and responsibilities.

Customize the plan based on the specific needs and characteristics of your project.

Cost estimation

Utilize appropriate cost estimation techniques to determine the anticipated costs for each activity and resource required for the project.

It can involve analyzing historical data, consulting subject matter experts, conducting market research, and using estimation tools and software.

Document the estimation process and assumptions made to ensure transparency and accuracy.

Budget creation

Develop a detailed budget based on the estimated costs.

Allocate resources and funds to different project activities, taking into account the cost estimates, project schedule, and funding constraints.

Define the budget in terms of labor costs, material costs, equipment costs, and any other relevant cost categories specific to your project.

Cost control and monitoring

Implement the processes and tools outlined in the cost management plan to monitor and control costs throughout the project lifecycle.

Regularly compare actual costs against the budgeted amounts, track cost variances, and analyze the reasons behind any deviations.

Conduct periodic cost reviews and audits to identify cost-saving opportunities, areas of inefficiency, or potential risks.

Change management

Establish change control procedures as defined in the cost management plan.

Whenever changes to the project scope, schedule, or other factors are proposed, evaluate their impact on the project's costs.

Assess whether the changes are within the approved budget or require additional funding.

Follow the defined approval processes for accepting or rejecting changes that may affect project costs.

Reporting and communication

Adhere to the reporting requirements specified in the cost management plan.

Prepare regular cost reports that provide accurate and up-to-date information on the project's financial status.

Communicate the reports to relevant stakeholders such as project sponsors, executives, and team members.

Clearly present the planned costs, actual costs, cost variances, and any significant cost-related issues or trends.

Continuous improvement

Regularly review and assess the effectiveness of the cost management plan.

Identify areas for improvement, such as refining cost estimation techniques, streamlining budgeting processes, or enhancing cost control measures.

Learn from past projects and incorporate lessons learned into future cost management practices.
