As experienced project managers, you already know that projects are not static. Instead, they are constantly in flux and can change shape at any time. As a project progresses over time, its cost can grow above the budget quite quickly. And keeping track of your budget is paramount to a project’s success.


What is project budget management?

Project management budgeting is key in project management. By putting project budget planning at the top of your priority list, and putting in measures to stick with it, you ensure you come away with more than you started. Starting a project without creating a project budget usually ends with failure, since the rule of thumb- in life in general- is that things always end up costing more than we thought!


What are the different project budget management methods?

  • Three-point estimating uses past information to judge the best-case estimate, the most likely estimate, and the worst-case estimate of a project in order to determine the most likely outcome. The project budget is then decided based on this figure.
  • Analogous estimating uses information from previous, very similar projects to guide the project budget. This technique is only good when there is little data available, as it can be difficult to get an accurate analogous estimate.
  • Bottom-Up Budgeting involves breaking down the costs for different parts of a project and adding them up to get an estimated budget.
  • Top-Down Budgeting means estimating the project total and dividing that by the number of tasks, allocating an appropriate amount for each task.
  • Parametric Estimation is a sophisticated budgeting method that combines industry data and knowledge from previous projects to reach a fairly accurate budget.

Now that we’ve defined some different types of budgeting methods, the question is:


How do you keep expenses under control?

4 tips to help you manage a project’s budget:



It’s simple: frequent budget oversight prevents a project from getting too out of hand. And a project without frequent re-forecasting will likely end in disaster. Updating and managing an inherently turbulent budget is a necessity for any project. As the project manager, it’s up to you to discuss budgeting in project budget management at team meetings. Talking to your team about upcoming spending can provide you with a realistic idea of where your project is heading.

Consistent re-forecasting also enables your team to anticipate the progress of a project. And it ensures that a project’s budget is in line with its anticipated completion date. Using a business intelligence tool such as Workamajig can be helpful in keeping the project budget process on track.



Any agency that has been in business for a length of time has experienced the horrors of scope creep. The scenario is usually similar: a project with a new client is going well, but over time, it grows bigger and bigger while your price remains the same.

Typically, this results in two outcomes:

  1. The client thinks that the extra work your team puts in is included in the original scope of work.
  2. The client simply has no idea that they are asking for more than was originally agreed upon.

It’s crucial to keep tabs on scope change at all times and realize that scope change will probably happen to your team. Create change orders for additional work that may pop up. Change orders prevent budget overrun by authorizing additional funding and covering the costs of extra work.



Just as your project budgeting needs consistent forecasting, you should do the same for your resources. After all, your resources are the bread and butter of your projects—and they do contribute to its overall cost. PMs should constantly re-forecast their resources by reviewing the number of people who are working on a project at a given time and anticipate the future on a weekly basis. This will ensure that you are utilizing the resources you currently have and that employees are working as efficiently as possible.



A project is only as good as its team—and a team with poor communication is sure to go over budget. Keeping your team informed of the project’s budget forecast will help encourage accountability and productivity. Encourage open communication to promote ownership of the project. And if employees care about a project’s outcome, they will subsequently produce stellar work.

With these four tips in mind, I’d like to add one caveat:

When it comes to project budgets, there is a lot of talk about coming in ‘under budget’, i.e. your project budgeting process is such that you’ll only take on a project if you’re certain you won’t have to go over budget for it, and you’ll take preventive steps along the way too. 

This sounds good in theory, but being over-cautious about a budget can actually cause agencies to lose out in the long run. This can happen if you end up taking on too few projects out of caution when in reality, you’re coming in far under budget with your other projects and could have easily taken on more.

The trick is to find a comfortable middle ground. You exercise caution when agreeing to new projects and keep a close eye on the budget as the project progresses, yet you’re also prepared to take minimal risks that are unlikely to be costly and offer you the opportunity to grow.


Using Project Budgeting Management Software

Calculating a project budget tends to take an awfully long time when calculated manually, e.g. using an Excel sheet. Hours are spent pouring over data and crunching numbers-hours that you could be spending on billable tasks. And that’s just the start-what about all of the time you spend ensuring the budget is on track mid-project? You could be spending a staggering number of hours keeping track of your budget (which in itself reduces your project budget as you have to factor in all that non-billable work!). We won’t even mention what an absolute bore this type of work is!

But you could avoid it-yes all of it, simply by using project budgeting software.
