What is project cost management?

Project cost management is estimating, budgeting, and controlling costs throughout a project’s life cycle. Its primary objective is to ensure that expenses remain within the approved budget.

For a project to be considered successful, it must fulfill the following criteria:

• Meeting the defined requirements and scope.
• Achieving a high standard of execution quality.
• Completion within the agreed-upon schedule.
• Staying within the allocated budget.

Therefore, project cost management stands as one of the fundamental pillars of project management, applicable across various industries such as manufacturing, retail, technology, construction, and more.

It plays a vital role in establishing a financial baseline that project managers can use to assess the status of their project costs and make necessary adjustments if necessary.

Why is project cost management important?

An efficient project cost management process enables project managers to:

• Set clear expectations with stakeholders.
• Control scope creep by establishing transparency with the customer.
• Monitor progress and promptly implement corrective actions.
• Maintain expected margins, increase ROI, and prevent financial losses on the project.
• Generate data for future project benchmarking and long-term cost trend tracking.

Understanding the significance of cost management is straightforward. To illustrate this, let’s consider the example of building a house as part of a project lifecycle.

• The first step is to establish a budget, which provides a sense of the project’s financial boundaries. Once the high-level budget is determined, it is further divided into expenses for sub-tasks and smaller line items.

The budget plays a critical role in making important decisions, such as choosing the right designer: one who can handle the entire project from start to finish or someone who can assist with specific elements while working within a smaller budget. Additionally, the budget helps decide the number of rooms in the structure and the quality of materials to be used.

Without a well-defined budget, answering these questions becomes challenging, and evaluating progress during the project becomes nearly impossible.

In larger organizations, this challenge is exacerbated by the concurrent running of multiple projects, changes in initial assumptions, and unexpected costs. This is precisely where the cost management process begins and becomes vital.

The four steps in project cost management

Cost management is a continuous process in the project life cycle, but breaking it down into four distinct steps can facilitate a better understanding and execution: resource planning, estimation, budgeting, and control. Though these four steps are typically sequential, adjustments may be required if resource changes occur during the project.

Let’s explore each step in detail:

1. Project resource planning

Resource planning involves identifying the necessary resources to execute and complete a project successfully. These resources may include personnel (employees and contractors) and equipment (such as infrastructure and specialized machinery).

This planning occurs at the project’s start before any actual work begins. Project managers develop a work breakdown structure (WBS) to evaluate each subtask’s resource requirements, such as the number of personnel with specific skills and the materials or equipment needed.

During resource planning, historical data, feedback from subject matter experts (SMEs), and the impact of time constraints on resource availability must be considered. Ground realities may require adjustments, such as hiring external contractors or providing training to internal teams.

2. Cost estimation

Cost estimation involves quantifying the expenses associated with all the required project resources. To calculate costs accurately, it’s essential:

• Resource requirements (obtained from the resource planning step)
• Prices of each resource (e.g., staffing costs, vendor fees, material rates)
• Duration for which each resource is required
• List of assumptions and potential risks
• Past project costs and industry benchmarks
• Insight into the company’s financial health

Estimation is a critical step, as deviations between estimated and actual costs can impact project success.

Various estimation models are available, such as analogous estimation, parametric modeling, and program evaluation and review technique (PERT).

Decisions regarding top-down or bottom-up approaches depend on available past costing data and project experience.

Cost estimation also aids decision-making during the planning phase by comparing multiple project solutions and evaluating cost reduction strategies, such as value engineering.

3. Cost budgeting

Project cost budgeting involves allocating costs to specific project segments, such as individual tasks or modules, over a defined time. Budgets may include contingency reserves to manage unforeseen expenses.

Budgeting creates a cost baseline against which project cost performance can be measured and evaluated. It enables the assessment of future funding requirements, allowing the project manager to set targets based on available financial resources.

4. Cost control

Cost control is a continuous process that monitors cost variances from the baseline and initiates appropriate actions to address discrepancies.

This step takes place throughout the project’s life cycle and relies on timely and transparent project reporting.

The cost management plan, detailing measurement criteria, deviation thresholds, corrective actions, and decision-making authorities, is an essential input for cost control. Earned value management (EVM) is a popular approach for measuring cost performance.

By measuring actual progress against planned progress and assessing schedule and cost variances, cost control provides decision-makers with transparency and the ability to respond promptly to project situations.

Project cost management formulas

To gauge the financial health of a project and assess its performance, project managers rely on several key formulas. These formulas help them measure cost efficiency, performance, and variances. Here are some essential ones:

Cost Performance Index (CPI)

The CPI indicates the value of work accomplished per unit of cost spent.

A CPI greater than 1 suggests efficient cost performance, meaning the project is getting more value out of every dollar spent. On the other hand, a CPI of less than 1 indicates cost overruns.

Cost Performance Index (CPI) = Earned Value (EV) / Actual Cost (AC)

Schedule Performance Index (SPI)

The SPI evaluates the project’s schedule efficiency.

An SPI greater than 1 signifies good schedule performance, indicating that the project is ahead of schedule. Conversely, an SPI of less than 1 indicates delays in the project.

Schedule Performance Index (SPI) = Earned Value (EV) / Planned Value (PV)

Cost Variance (CV)

The CV measures the variance between the earned value (the value of work performed) and the actual cost incurred.

A positive CV implies cost savings, while a negative CV suggests cost overruns.

Cost Variance (CV) = Earned Value (EV) – Actual Cost (AC)

Estimate at Completion (EAC)

The EAC predicts the expected total cost of the project based on current performance.

It considers the budget at completion and the cost performance index to estimate the total cost of the project.

Estimate at Completion (EAC) = Budget at Completion (BAC) / Cost Performance Index (CPI)

Project cost management techniques

Implementing effective cost management techniques is vital to controlling project expenses and ensuring financial success. Here are some essential techniques:

• Bottom-up estimating: This technique involves breaking down the project into smaller, more manageable tasks and estimating the cost of each component individually. Summing up these estimates provides a more accurate overall project cost estimation.
• Reserve analysis: Projects are inherently prone to uncertainties and unexpected events. Reserve analysis involves setting aside contingency reserves to account for potential risks. These reserves act as a buffer to handle unforeseen circumstances without affecting the primary project budget.
• Parametric estimating: This technique involves using historical data and statistical relationships to estimate costs. Project managers use historical cost data from previous similar projects and apply it to the current project, factoring in variables like size, complexity, and other relevant parameters.
• Analogous estimating: Also known as top-down estimating, this technique relies on expert judgment and historical data from past projects to estimate the current project’s costs. It is particularly useful in the early stages of a project when detailed information is limited.
• Earned Value Management (EVM): EVM is a powerful technique that integrates project scope, schedule, and cost to assess project performance and predict future outcomes. It allows project managers to measure progress objectively and identify deviations from the approved budget and schedule.

Project cost management tools

In the digital age, project management tools have become indispensable for efficient cost management. These tools not only streamline processes but also enhance accuracy and collaboration. 

There are several project management tools and software that will boost your performance and productivity as a project manager, for example, project management cost software, workload management tools, resource management and planning tools, and time tracking tools like:

Who is responsible for cost management in a project?

Project cost management is part of the role and responsibility of the project manager. But, at the same time, it is a collaborative effort involving all stakeholders.

The project manager oversees the cost estimation, budget allocation, and cost control activities while ensuring adherence to the approved financial plan. However, the success of cost management relies on the active participation and support of team members, financial experts, sponsors, and clients.

Challenges of cost management and how time tracking will help

Despite its significance, project cost management comes with its share of challenges. Addressing these challenges effectively is crucial to achieving project objectives. Common challenges include:

• Inaccurate estimations: Poorly estimated costs at the project’s initiation can lead to significant budget deviations and financial strain during execution. To prevent the risk of inaccurate estimation, we recommend using a time-tracking tool to provide historical data to benchmark when estimating new projects.
• Scope creep: Uncontrolled changes or additions to project scope can disrupt budget planning and cause cost overruns. Still, time tracking can prevent scope creep by revealing which activities take up most of the team’s time in advance.
• Resource constraints: Limited availability of resources can hinder cost optimization and project efficiency, leading to compromises on project quality. Time tracking again is a precious help to prevent resource restrictions by tracking the team’s time, you’ll know who’s overworking and will promptly make a decision.
• Stakeholder expectations: Balancing stakeholder expectations, especially when faced with tight budgets and limited resources, can be challenging for project managers. One last thing: time tracking can help manage stakeholder expectations. With past-time tracking data about your team, you’ll know how long each task will take. Hence, you won’t incur the risk of overpromising something to stakeholders.
