Burndown Chart: What It Is, How it Works, and How to Use It (2026)

A burndown chart is a simple way to visualize how much work remains to be completed within a defined period, such as a Scrum sprint or a specific phase of a project. Instead of relying only on reports or verbal updates, the team can see in a single view whether the pace of work is aligned with the planned objectives.

In many projects, the biggest challenge is not starting the work, but knowing whether you are actually progressing at the right pace.

A team may have a clear task list, well-organized meetings, and an ambitious roadmap, yet still reach the end of a sprint with the feeling that time ran out before the work was completed. When this happens repeatedly, it usually indicates that the team lacks sufficient visibility into its real progress.

For this reason, the burndown chart has become one of the most widely adopted agile metrics. It not only helps monitor team progress but also makes it easier to detect potential delays before they turn into larger issues.

In addition, its value is not limited to technical teams. Project managers, product leaders, and operations teams use this type of project tracking chart to improve transparency, facilitate coordination across teams, and make faster, more informed decisions.

In this article, we will explore what a burndown chart is, how it works within Scrum, how it differs from other tools like the burn-up chart, and how to create a burndown chart that truly helps your team manage projects more effectively.

What Is a Burndown Chart?

A burndown chart is a visual tool used to track a team’s progress over a defined period of time, such as a Scrum sprint or a specific phase of a project. Its main purpose is to show how much work remains to be completed over time.

In simple terms, a burndown chart answers a key question for any project manager: are we progressing at the right pace to finish the project on time?

A typical scrum chart is represented using two main axes:

• Horizontal axis (X): represents time, usually the duration of the sprint or project
• Vertical axis (Y): represents the amount of remaining work, typically measured in story points, tasks, or estimated hours

As the team completes tasks, the line on the chart trends downward, showing how the total remaining work decreases over time. This is where the term burndown comes from. It reflects the idea of “burning down” the backlog as work gets completed.

Key elements of a burndown chart

Although there are variations, most burndown charts include a few essential components:

• Total work scope: the full amount of work defined at the beginning of the sprint
• Ideal progress line: a projection of how work should decrease if the team progresses at a steady pace
• Actual progress line: the real, day-to-day progress of the team
• Remaining work: the amount of work left at any given point in time

Comparing the ideal and actual lines allows teams to quickly identify whether they are ahead, behind, or on track.

To better understand how it works, reviewing a burndown chart template can be helpful, especially to see how the remaining work line evolves across a sprint.

Why burndown charts are essential in Scrum

In agile environments, transparency is critical. Teams that rely on collaboration tools such as Scrum boards, task managers, or project platforms also need a clear way to visualize progress.

It also helps uncover important patterns, such as:

• work piling up toward the end of the sprint
• unrealistic estimations
• blockers that slow down progress
• inconsistent burndown rate across days

In other words, a burndown chart does not just show progress. It helps teams understand how work is actually happening over time.

Burndown charts and data-driven decision-making

Another key advantage of using a burndown chart is that it supports a more analytical approach to project management.

When teams rely on agile metrics instead of intuition, they can detect issues earlier and adjust their strategy before delays become critical. If you want to explore this mindset further, you can read our article on data-driven decision-making, where we explain how organizations use real data to improve operational performance.

From this perspective, a burndown chart is not just a visual aid. It is a practical way to turn project progress into actionable insights.

Now, while the burndown chart is one of the most common project tracking charts, it is not the only way to visualize progress. Another widely used alternative is the burn-up chart.

In the next section, we will explore how they differ and when to use each one.

Burndown Chart vs Burn-up Chart

When teams start working with agile methodologies, it is common to come across two very similar visual tools: the burndown chart and the burn-up chart. Both are used as project tracking charts, but they present progress in slightly different ways.

Understanding the difference between these two helps teams choose the right tool depending on the type of project, how stable the scope is, and how they want to interpret their agile metrics.

What a burn-up chart shows

A burn-up chart presents progress from a different perspective than a burndown chart. Instead of focusing on what is left, it shows what has already been completed.

In this type of chart:

• one line represents the total scope of the project
• another line represents completed work over time

As tasks are completed, the progress line moves upward until it reaches the total scope.

One key advantage of the burn-up chart is that it makes changes in scope more visible. If new tasks are added or the backlog evolves, the total scope line adjusts accordingly, providing more context for interpreting progress.

Key differences between both charts

Although both tools serve a similar purpose, there are some important differences:

Burndown chart

• Tracks remaining work
• The line moves downward as tasks are completed
• Commonly used as a scrum chart in sprint-based work
• Easier to use when scope is clearly defined
• Helps teams understand how to read burndown chart trends over time

Burn-up chart

• Tracks completed work
• The line moves upward as progress accumulates
• Better at reflecting scope changes
• Useful in projects with evolving requirements

When to use each one

In practice, many agile teams prefer the burndown chart because it is simple, direct, and easy to interpret during daily standups.

However, in projects where the scope frequently changes, the burn-up chart can provide a more complete picture of progress and expectations.

In both cases, the real value of these tools lies in how they help teams identify issues early, adjust their workflow, and maintain visibility over the project.

How to Create a Burndown Chart

Although a burndown chart may seem like a complex tool at first, it is actually quite simple to build when the project is well defined. 

Below are the main steps to create a burndown chart within a Scrum environment or any agile project.

1. Define the scope of work

The first step is to identify all the tasks that will be included in the sprint or project phase you want to track.

Many teams approach this using a top-down method. Instead of starting with small tasks, they define the main project goals first and then break them down into more detailed activities.

This process is often supported by:

• product backlogs
• user stories
• a work breakdown structure
• documentation stored in knowledge management systems

For example, a software development team might begin with a high-level goal, such as building a new feature. That goal is then broken down into smaller tasks like UI design, backend development, testing, and documentation.

2. Estimate the total workload

Once the tasks are defined, the team needs to estimate the total amount of work.

In Scrum, this is typically done using:

• story points
• number of tasks
• estimated hours

For instance, if a team estimates 40 story points for a two-week sprint, that number becomes the starting point on the vertical axis of the burndown chart.

From there, each completed task reduces the remaining workload, creating the downward trend in the chart.

Many teams use a burndown chart template in spreadsheets or project management tools to standardize how this data is tracked and visualized.

3. Set the time frame

The horizontal axis of the burndown chart represents time.

In most Scrum teams, this corresponds to the sprint duration, usually one or two weeks. However, it can also be applied to longer project phases.

Examples include:

• a 10-day sprint
• a 30-day development phase
• a product implementation stage

During this period, the team tracks the remaining work on a daily basis.

4. Update the chart consistently

A burndown chart is only useful if it is updated regularly.

For this reason, many teams review and update the chart during daily standups or sprint check-ins. These conversations can take place in different environments, from virtual meetings to in-person sessions in meeting rooms, where teams review project boards and progress metrics together.

For example, a product team working on a new platform might update the chart every morning based on the previous day’s completed work. This allows them to maintain an accurate view of their burndown rate.

Regular updates make it easier to understand how to read burndown chart trends and identify whether progress is on track.

5. Analyze deviations from the plan

The real value of a burndown chart comes from analyzing the difference between the ideal progress line and the actual progress line.

For example:

• If the actual line decreases more slowly than expected, tasks may have been underestimated.
• If progress drops sharply near the end of the sprint, work may be accumulating too late.
• If the line remains flat for several days, it may indicate blockers or coordination issues.

Looking at a burndown chart example can help teams recognize these patterns more easily and understand how to react.

For instance, a marketing team working on a campaign launch might notice slow progress in the first days of the sprint. By analyzing the chart, the project manager could identify dependencies, delays in content production, or misalignment between teams.

Now that we understand how to build one, the next step is to explore why so many agile teams rely on burndown charts as a core part of their workflow.

Benefits of Using a Scrum Chart 

Some of the most important benefits of using a burndown chart include:

• Clear visibility into project progress: A burndown chart allows teams to instantly see how much work remains and whether they are aligned with the original plan.
• Early detection of delays: When the actual progress line begins to diverge from the ideal line, teams can quickly identify risks and adjust their approach before delays escalate.
• Improved team alignment: By using a shared project tracking chart, all team members gain a better understanding of how their work contributes to overall progress.
• Greater transparency for stakeholders: Project managers, team leads, and stakeholders can easily interpret the status of the project without needing long status reports.
• More productive check-ins and meetings: Whether in daily standups or strategic sessions in private offices, the burndown chart helps keep discussions focused on measurable outcomes and agile metrics.

Ultimately, a burndown chart serves as a continuous feedback mechanism. It transforms progress into actionable insight, enabling teams to make faster and more informed decisions.

Now that we have explored its benefits, the final step is to understand why the burndown chart continues to be a core tool in modern agile project management.

Beyond the Chart: Why Burndown Charts Still Matter in Agile Projects

More than just a reporting tool, the burndown chart transforms progress into something tangible. By showing how work evolves over time, it allows teams to interpret patterns, anticipate risks, and adjust their approach before issues become critical.

One of its greatest strengths is simplicity. Unlike more complex dashboards or reporting systems, a burndown chart can be understood quickly by anyone involved in the project. This makes it an effective project tracking chart not only for technical teams, but also for stakeholders who need a clear and immediate view of progress.

It also plays an important role in building better habits. Over time, teams that consistently use burndown charts become more disciplined in how they estimate work, track progress, and reflect on performance.

At its core, effective project management is not just about completing tasks. It is about understanding progress, identifying obstacles early, and creating conditions where teams can move forward consistently.

A well-used burndown chart may be simple, but it remains one of the most reliable tools for achieving exactly that.
