Put simply, a cost breakdown structure helps you regain cost control and organize project budgets.<\/p>\n
While you can track these numbers manually, there\u2019s an easier way to get your cost breakdown structure. Click the button below to see for yourself, or keep reading for a quick tutorial on how to create your structure.<\/p>\n
Get started<\/a><\/p>\n Making your own cost breakdown structure doesn\u2019t have to be complicated. Here are five key steps to create your own cost breakdown structure.<\/p>\n Before you can identify costs, you need to determine what each stage of your project entails. The project life cycle<\/a> has five key stages:<\/p>\n Then, once you’ve determined each stage of the lifecycle you can start to map out your project expenses.<\/p>\n The next step is to estimate the work cost for each task or activity in each stage of your project lifecycle. For instance, costs during the initiation stage might include your choice of project management Work OS platform.<\/p>\n It\u2019s worth noting that estimating costs for different tasks can be challenging, especially if you’re not directly involved in the implementation of those specific tasks. Luckily, there are a few different techniques to help you estimate costs, including parametric estimation, one of the formula-driven estimation tools based on data from previous projects.<\/p>\n Once you’ve estimated the costs of work for all stages of the project management lifecycle, you can use them to work out the final costs for your project.<\/p>\n No matter how accurate your estimates are, it\u2019s always worth adding in a contingency plan<\/a>.<\/p>\n For example, one of your team members may get sick, making them unable to complete a task on time. Building in some contingency will improve the accuracy of your cost structure when changes occur.<\/p>\n monday.com tip: We suggest including overhead costs in your cost breakdown structure, so you get an accurate estimate of what you\u2019ll need and spend.<\/p>\n By overhead costs, we\u2019re talking about various costs that aren’t task-specific but are important for the company and project, such as administrative costs.<\/p>\n It\u2019s also good practice to check your estimates against your available budget. So, once you\u2019ve created your cost breakdown structure, check whether your total estimated cost matches up with your initial estimates.<\/p>\n If your cost breakdown structure comes out higher, you can always look at ways to manage costs.<\/p>\n The last step in creating a cost breakdown structure is to assign costs to your project management platform. For example, on monday.com you can add costs to each individual element of your project, set up formulas, automations for when you go over budget, and much more.<\/p>\n Instead of relying on messy spreadsheets, adding costs into your work software provides visibility and transparency to key stakeholders and much better insight into costs for each project stage.<\/p>\n In the next section, we\u2019ll walk you through this in more detail.<\/p>\n Once you have a solid approach to managing your cost breakdown structure, you’ll have better control of project costs to avoid going over budget. Although the process can seem daunting, you can use monday.com Work OS to help in the process.<\/p>\n Through allocating costs to individual tasks on a project board you\u2019ll be able to access data for your cost breakdown structure in a fraction of the time. The great thing about this is that you can add up the costs in chunks so you could create an overall cost for a project or for a particular level of task.<\/p>\n You can use a Numbers Column for budget targets, and a Numbers Column to see what you’ve spent.<\/p>\n Plus, you don’t have to do the math every time you want to know where you stand. You can add an “If” formula, which takes the delta of the two numbers and sends the message “Within Budget” when you\u2019re below or have met the intended budget, or “Over Budget” when you\u2019ve exceeded budget.<\/p>\n Additionally, to reduce the amount of manual work you and your team needs to do, you can add in automations such as due dates and reminders, recurring tasks and events, and more!<\/p>\n Finally, dashboards are a great place to keep all of your costs in one place. You can even connect several boards to one dashboard to compare and contrast stats, numbers, and progress.<\/p>\n Get started<\/a><\/p>\n Spreadsheets are popular for cost breakdown structures, yet there are some limitations, which may not make them the best choice for everyone. Typically, spreadsheets are not that easy to share, they are not user-friendly, and visualizing costs is difficult.<\/p>\n In contrast, using a cost management platform<\/a> like monday.com to split costs across your project plan<\/a> provides a much clearer view and management of costs.<\/p>\n You can see a committed view of spend across specific items on a project board and see how costs stack up overall by combining several boards into one dashboard.

A Cost Breakdown Structure (CBS) assigns a cost to each of those tasks and deliverables-it defines the 'how much.' You typically create the WBS first and then use it as a foundation to build your CBS.<\/p>\n"},{"question":"What are the main cost categories in a CBS?","answer":" The main cost categories in a CBS are direct costs (expenses tied to a specific task), indirect costs (general overhead like rent), labor costs (salaries and wages), material and equipment costs, and contingency reserves (a budget buffer for unexpected expenses).<\/p>\n"},{"question":"How do you calculate contingency costs for a project?","answer":" Contingency costs are typically calculated as a percentage of the total estimated project cost. A common practice is to set aside 5% to 10% of the total budget as a contingency reserve. This fund is used to cover unforeseen risks or changes that could impact the project's finances.<\/p>\n"},{"question":"What is the best software for creating a cost breakdown structure?","answer":" While spreadsheets like Excel can work for simple projects, the best software for a cost breakdown structure is a comprehensive Work OS like monday.com.

The goal here is to turn broad project requirements<\/a> into a clear financial structure that\u2019s easy to track and update as work progresses.<\/p>\n Start by confirming the full scope of work. Most teams do this using a work breakdown structure<\/a> because it outlines every deliverable, phase, and task. The more complete your scope, the more accurate your cost breakdown will be.<\/p>\n Once the scope is set, identify every cost tied to the work. This includes labor, materials, equipment, external services, software, and any other expenses.
