Project budget: definition, steps, example & template

Just as a vehicle needs fuel to reach its destination, projects need money and resources to move forward. As a project manager, you have the power to plan and allocate those resources effectively, ensuring your project stays on track without running dry

Because a project budget is essential to move work forward, knowing how to create and follow a solid budget plan is one of the most important project management skills you can develop over the course of your career.

What is a project budget?

A project budget is an approved financial plan that outlines how much money you'll spend, what you'll spend it on, and when expenses will occur throughout your project. It serves as both a planning tool and a control mechanism, helping you allocate resources effectively and track actual spending against projections.

Creating a budget in advance reduces the likelihood of running out of resources or overspending. Research consistently shows that a significant portion of projects exceed their original budget, making effective budgeting a critical skill for project managers.

Budgeting before you begin your project helps you scope work and control costs. It's also a good way to pitch your project to stakeholders and get the funds you need, because a detailed spending plan helps approvers understand how costs contribute to your objectives. And as your project progresses, you can use your project budget as a baseline to compare actual spend to budgeted spend and mitigate extra costs as they arise.

To make the process easier, you can start with a ready-made budget template that adapts to a range of needs, from small projects to complex financial plans.

What should a project budget include?

A comprehensive project budget accounts for all expenses you'll encounter throughout your project. Understanding the different cost categories helps ensure nothing falls through the cracks. Here are the key components to include:

• Direct costs: Expenses directly tied to your project, such as labor, materials, equipment, and software licenses.

• Indirect costs: Overhead expenses that support the project but aren't exclusively tied to it, like utilities, administrative support, and facility costs.

• Fixed costs: Expenses that remain constant regardless of project scope, such as software subscriptions or contracted services.

• Variable costs: Expenses that fluctuate based on project activity, like hourly contractor rates or material usage.

• Contingency reserves: Buffer funds set aside for unexpected costs or risks that may arise during execution.

Why do you need a project budget

Creating a project budget isn't just a box to check; it's a foundational step that sets your project up for success. Here's why budgeting matters:

• Cost control: A budget gives you a clear spending roadmap, helping you avoid overspending and catch cost overruns early.

• Stakeholder alignment: When you present a detailed budget, stakeholders can see exactly how funds will be used, making it easier to secure approval and maintain trust.

• Resource optimization: Budgeting forces you to think critically about resource allocation, ensuring you're achieving operational efficiency with your team's time and tools.

• Decision-making clarity: When unexpected changes arise, your budget serves as a reference point for making informed trade-offs.

• Project accountability: A budget creates a benchmark for measuring financial performance, helping you track cost variance and demonstrate results.

Without a budget, projects are more likely to experience scope creep, missed deadlines, and strained team resources. By investing time upfront to build a solid budget, you're setting the foundation for smoother execution and better outcomes.

9 steps to create a project budget

Creating a project budget may seem daunting, but you can do so by following a step-by-step process. We've laid out each part of the budgeting process below.

1. Set project objectives

Project objectives are what you plan to achieve by the end of your project. They're a good place to start because they help you understand where work is headed, and act as a north star while you iron out the rest of your project plan.

The best objectives are clearly defined and measurable, so you can use them as a benchmark for success. To write clear objectives, use the SMART methodology:

• Specific: Clearly define what you want to achieve

• Measurable: Include metrics to track progress

• Achievable: Ensure the goal is realistic given your resources

• Realistic: Align the objective with broader business goals

• Time-bound: Set a clear deadline for completion

For example, if you're trying to boost website visitors, you might set this objective: "By the end of this quarter, increase organic traffic to the website homepage by 10%."

2. Define project scope

Once you've set your objectives, you can determine the scope of work needed to achieve them. Your project scope sets boundaries for your project, such as what work you'll do and what you won't, and what deadlines and deliverables you're working towards. When defining your project scope, consider the following:

• Available resources: Before you determine the specific deliverables you want to target, take stock of the resources you have. If you're working with a hard budget cap or limited project team bandwidth, you may need to adjust your deliverables accordingly. As such, it's useful to be aware of any limitations before you dive into the details of deliverables and required resources (which we'll get to in later steps).

• Time constraints: Is there a deadline for this project, or can you take as long as you need? A tight project schedule can affect resource costs. For example, you may need to pay freelancers a rush rate if you're working with a tight deadline.

• Non-goals: What's outside the project scope? It can be helpful to identify what you're not trying to achieve, so you can avoid scope creep and potential overspending.

Remember that your project scope is all about setting boundaries. It helps you understand what you want to achieve, what type of work you'll do, and what deliverables you're working towards.

3. Break deliverables into sub-dependencies

Next, list all deliverables within your project scope and break them down into sub-dependencies. For example, imagine that one of your project deliverables is to publish a blog post. You might break it down into the following line items:

• Draft blog

• Edit blog

• Create design images

• Stage in Wordpress

• Share on social media

This method helps you include hidden project expenses when creating your budget. For example, if you just tried to estimate the budget for publishing a blog post as a whole, you'd be more likely to omit extra costs, such as the hourly rate for a freelance editor or the price of paid social posts.

If you prefer diagrams over lists, try creating a work breakdown structure (WBS). This visual tool breaks down work into multiple levels, starting with your main objective at the top and branching out into deliverables and sub-dependencies below.

4. List required resources

Now that you've laid out all of your deliverables and sub-dependencies, it's time to list the resources required for each item. Be as specific as possible, and remember that "resource" can mean more than just staff or equipment; it may also include indirect costs such as training or a physical workspace.

To get you started, here are some common project cost categories to consider:

• Team members: Who are you relying on to do the work? Make a note whether they're in-house salaried staff or if you need to hire additional hourly contractors.

• Procurement: What do you need to do to acquire external resources? For example, you may need a team member to research the best products to use, communicate with sales reps, and purchase a tool.

• Training: Do team members need time or resources to get up to speed? Think of the time needed for staff to train new employees or the courses required to learn new skills.

• Equipment: What tools are required? This can include items such as extra computer monitors, design software, or even internet service.

• Space: Where is your team going to work? For example, consider whether you'll require meeting rooms or desk space for new team members.

• Research: What data do you need? Think if you'll rely on information like user research studies, web analytics, or polling.

• Professional services: Do you need to hire external experts, like legal or marketing consultants?

• Travel: Does your team need transportation, lodging, or an allowance for on-the-go meals?

5. Estimate amounts

Ultimately, a budget is an estimate of costs. But while we can't predict the future, there are a few methods to help you make the most accurate estimates possible. And you don't have to stick to just one; you can use a combination of these approaches, depending on your unique project circumstances.

Here are four estimation techniques you can use:

You don't have to stick to just one method. For example, you might use a bottom-up estimate for known deliverables, then cross-check it against historical data from a similar project to catch any gaps.

6. Set aside a contingency fund

Sometimes, the unexpected happens. Tools break, schedules change, and once-in-a-century pandemics make things a bit harder. Or you might uncover an unexpected opportunity during your project, such as the chance to purchase a business asset at a reduced cost.

Contingency reserves give your budget extra padding when plans change. The typical recommendation is to set aside 5-10% of your total budget for contingencies.

Budgeting is an estimation process, so you should always include a contingency fund. And if you've created a 100% accurate budget and don't need that extra padding, you can bolster your company's bottom line with the leftover funds.

7. Build your budget

At this point, you've identified all of your project's deliverables, allocated resources, and estimated costs. Now, it's time for the fun part: creating your actual budget document. Here are some key components to include:

• Line items for each deliverable, sub-deliverable, and required resource, plus the expected cost of each.

• A timeline of when you'll need each resource, and when you expect to spend funds.

• The person responsible for each budget component. For example, you might note that your assistant editor is responsible for tracking freelancer hours and invoices.

• Clear documentation of which part of the company budget you'll pull from for each line item. For example, you may use the marketing department budget to create video ads, and the IT department budget for computer upgrades.

• A total of expenditures for your entire project. If applicable, include individual totals for each department budget you'll be using.

• A place to track actual costs vs. budgeted costs once your project kicks off.

Project budgeting tools

Selecting the right project budgeting tool is important, too. Make sure the program you choose has functionality to automatically total dollar amounts, so you don't have to manually recalculate every time you need to adjust a line item. Also, your chosen tool should let you easily share and update your budget in real time, so you can ensure all team members are working with the most up-to-date version.

There are many options, including basic Excel spreadsheets and more robust project management software. Not surprisingly, we're partial to Asana because it lets you input and total line items, build custom fields, assign owners, and easily share information with teammates. And aside from your actual budget, you can iterate on past workflows, create process documents, and save project budget templates to ensure you're not missing any steps.

8. Make a plan to monitor spending

A budget is only good as long as you stick to it. Plan in advance how often you'll keep tabs on actual costs vs. budgeted costs, so you can mitigate potential issues before they get too big. You can also decide up-front what you'll do if you go over (or under) budget.

The benefit of a tool like Asana is that it lets you share, manage, and track your budget in real time. For example, Asana's Universal Reporting feature automatically pulls data from your projects and displays spend, task status, and completed milestones in one place, so you don't have to dig to see if you're on track.

9. Get approval from key stakeholders

Now that you have your project budget plan in hand, it's time to share it with project stakeholders and ask for sign-off. Thankfully, the detailed plan you've made should give approvers a crystal clear picture of how each individual line item will contribute to your project objectives.

Example of a project budget

Let's say you're updating the checkout flow for your mobile app, and your project objective is to decrease average checkout time by 25% in Q3. To achieve that goal, you've scoped two priority deliverables and outlined the required resources.

Here's a simple example of what your project budget might look like. Note that you've included the timeline, owner, and estimated cost for each. You've also indicated which department budget you'll use for each line item, and added columns to track budget approval and actual spend.

Common project budget challenges and how to overcome them

Even with careful planning, project budgets can go off track. Understanding the most common challenges helps you prepare for them and respond effectively when they arise.

Scope creep and unplanned changes

Scope creep happens when new requirements, features, or tasks get added to a project without corresponding budget adjustments. Left unchecked, it can quickly drain your resources and derail your timeline.

How to overcome it: Establish a clear change control process from the start. When new requests come in, evaluate their impact on the budget and timeline before approving them. Document all scope changes and communicate them to stakeholders promptly.

Inaccurate cost estimates

Underestimating costs is one of the most common budgeting pitfalls, especially for projects with unfamiliar requirements or new team members.

How to overcome it: Use historical data from similar projects to inform your estimates. When data isn't available, use three-point estimation (optimistic, pessimistic, and most likely scenarios) to create a more realistic range. Build in contingency funds to absorb unexpected costs.

Communication gaps

When team members and stakeholders aren't aligned on budget status, small issues can snowball into major problems. Lack of visibility into spending can lead to surprises that erode trust.

How to overcome it: Schedule regular budget check-ins and share updates proactively. Use a centralized tool that everyone can see in real time to view spending data. Create clear escalation paths so budget concerns get addressed quickly.

Mid-project budget cuts

Sometimes external factors force budget reductions after a project is already underway. This can feel disruptive, but it doesn't have to derail your work.

How to overcome it: Prioritize your deliverables and identify which are essential and which are nice-to-have. Work with stakeholders to adjust the scope rather than compromising quality. Be transparent about trade-offs so everyone understands the impact of budget changes.

Project budget vs. project estimate

While the terms are sometimes used interchangeably, a project budget and a project estimate serve different purposes in the planning process.

Think of it this way: an estimate helps you decide whether to pursue a project, while a budget guides you once you've committed to it.
