Avoiding cost overrun is key to closing a successful project. The quality of deliverables and a timely execution can go out the window if the project is delivered over budget.
Of course, it’s easy to say you’re going to keep a tight budget. But cost overrun can happen in so many places that keeping costs down can sometimes feel like a game of whack-a-mole.
What Is Cost Overrun?
The term cost overrun refers to unexpected costs that end up exceeding a project budget. Cost overrun can occur in any project and it’s particularly common in construction, manufacturing and software development projects. Cost overrun is also known as a cost increase or budget overrun and can be caused for several reasons.
Before we delve into the reasons that projects can go over budget, let’s look at project management software that can help you prevent cost overrun. ProjectManager is software that collects real-time data to help you better monitor your expenses. Our live dashboard automatically collects and calculates six project metrics, including cost, and displays them in colorful, easy-to-read graphs. Unlike lightweight tools, there’s no setup required.

Main Causes of Cost Overrun
Cost management can be an exhausting task. As a project manager, you’ll constantly need to check your project costs to make sure things are going well at all times. In addition to this, you’ll also need to monitor other project constraints such as time, scope, risk and quality.
We’ve listed the main causes of cost overrun below so you can avoid this issue and deliver your projects on time and under budget.
- Bad project estimates: Cost estimation is critical for success in project management because every project manager must estimate all project costs before creating a project budget. Make sure to use all of the tools at your disposal such as historical data or a panel of experts to help you define project costs. If your project budget is insufficient, you’re very likely to face cost overrun.
- Scope creep: Scope creep occurs when your project scope isn’t well defined. In simple terms, this means that you’ll have unexpected tasks popping up during the execution phase. Executing unforeseen tasks increases your costs, making it very likely to exceed your project budget and cause cost overrun.
- Poor risk management: Any project faces many potential risks. It’s the responsibility of the project manager and the project management team to create a risk management plan that describes all the potential risks and the mitigation strategies to be implemented if needed. When a risk management plan is not created, you can have unexpected risks affect your project, which brings costs up and therefore, causes cost overrun.
- Lack of communication: A project is an endeavor that requires teamwork and communication. As a project manager, you must be the glue that keeps your project sponsor, project team and project stakeholders together. Lack of communication can result in unexpected changes to the project plan or prompt other issues that could cause cost overrun.

How to Avoid Cost Overrun
Cost overrun, or any sort of expense that pushes a project past the agreed-upon budget is something with which a project manager must be constantly vigilant. There are several ways one can prevent cost overrun.
Here are seven tips to help keep reigns on your budget.
1. Thorough Project Planning
The best way to stop cost overrun is to plan against it before executing a project. The more thorough and accurate your estimates, the more likely you’ll stay within budget. The project risks can be accounted for with an exhaustive risk management plan. When planning for any project, you must consider all possible scenarios and use historical data, interviews and experience. Once that plan has been detailed, have it signed off by the stakeholders of the project so everyone is on the same page in terms of expectations.
2. Know Your Vendors
Many projects require seeking assistance from outside vendors, whether to help with specific tasks or supply materials and equipment. A relationship with any outside vendor opens your project up to cost overruns that are often beyond your control. This makes it critical to do due diligence before relationships are cemented.
First, understand the capacity of the vendor and if they’re going to meet your needs. When the vendor quotes a cost, make sure it’s accurate. Then, before signing the contract, do a bit of background-checking to see if the vendor meets deadlines and see what others have to say about working with them.
3. Keep to Planned Scope
Scope creep is one of the biggest threats to sending a project into cost overrun. Change requests always bog down the desks of project managers. These come from stakeholders or clients, but also from team members. They all have wants and needs. Many of them may be appropriate and even beneficial to the project. However, too many changes can drastically impact the project, making cost overruns unavoidable. Put thought into the big picture before you increase project scope.
4. Use a Project Planning Tool
It’s a given that a powerful tool will make make a project manager’s work easier, add to the productivity of the project and increase efficiencies. It also assists in keeping cost overruns at a minimum. A scheduling tool like a Gantt chart can help keep the project on track and prevent cost overruns.
5. Keep Stakeholders Updated
If there isn’t a clear line of communication between stakeholders and project managers, delays are inevitable. Delays lead to cost overruns and there’s too great of a risk that work will start on the wrong task at the wrong time. This wasted time threatens to send the whole project off track.
Stakeholders, as well as teams, need proper communication, but each should get the right information. Teams want details while stakeholders want broad strokes to make sure the project is progressing as planned.
6. Monitor Progress
The real-time dashboard from ProjectManager is also ideal for tracking the progress of a project as it happens. Before issues become problems that threaten the project’s schedule and budget, they can be resolved. The real-time dashboard measures not only the project’s progress but the team’s workload and timelines for planned and actual completion, including project slippage and more.
7. Reassign Resources
If you discover a project that’s spending more than budgeted, you’re going to respond by reallocating resources. But you can also prepare for that scenario by evaluating resources beforehand and placing them where they’ll be most effective. This is especially true with your most valuable resource: your team.
By assembling the most experienced and skilled team members, you can have a more productive and efficient project. These resources might cost more, but if you’ve done your planning and set aside funds, you’ll save money on the backend when there are fewer issues to handle.
