TL;DR: Most burndown chart guides show you what the chart looks like and leave you there. This one covers how to build one, how to read the deviation patterns that actually matter, and what to do when your sprint goes off course. If you manage an IT team and want to stop guessing at sprint health, the interpretation layer is where this gets useful.
A burndown chart is a graph that shows how much work remains in a sprint over time. The horizontal axis tracks time, typically the days in a sprint. The vertical axis tracks remaining work, measured in story points or hours depending on how your team estimates.
At the start of a sprint, you plot the total work committed. A straight diagonal line runs from that starting point down to zero on the final day. That line is your ideal burndown. Your team then plots actual remaining work each day, creating a second line that shows real progress against the plan.
The gap between those two lines is where agile project management chart data becomes actionable. When the actual line runs above the ideal, the team is behind. When it flattens, work has stalled and you can diagnose why your actual line has gone flat before the sprint ends.
According to Atlassian, burndown charts are most commonly used to track progress across a sprint, giving teams a shared view of whether they're on pace to meet their goal.
Before the chart can show you anything useful, you need to set up your sprint scope and task list with enough precision that daily updates reflect real status, not guesswork.
A burndown chart does one thing well: it shows whether your team is on track to finish the sprint before you run out of time to do anything about it.
For burndown chart sprint planning, the previous sprint's chart is your most honest input. If your actual line stayed flat for two days mid-sprint, that's a blocking pattern worth addressing before you commit to the next sprint's scope. Most teams skip this step and repeat the same capacity mistake.
During the sprint itself, the chart gives you three concrete signals:
Ahead of the ideal line: scope may be underestimated, or the team has capacity to pull in backlog items
Tracking the ideal line: the sprint is healthy; keep the daily standup focused on blockers, not status
Below the ideal line (work remaining is too high): a risk is active, and you need to act now, not at the retrospective
For sprint progress tracking, daily updates matter more than the chart itself. A chart updated every three days is a history lesson. Updated daily, it's an early warning system.
You can view sprint health alongside workload and risk data to catch when the flat-line pattern means a blocker versus when it means the team is under-logging work. Those look identical on a burndown chart alone, but the fix is completely different. Knowing which one you're dealing with is what diagnose why your actual line has gone flat helps you do.
Building an agile burndown chart takes about 30 minutes to set up correctly. Rushing the setup is where most teams go wrong — they skip scope definition or forget to draw the ideal line, then wonder why the chart tells them nothing useful by day three.
Here are the six steps to do it right.
Define your sprint scope: List every user story or task included in the sprint before you write a single number. If your backlog isn't clean, your chart will be wrong from the start. This is also where set up your sprint scope and task list before estimation saves you a rewrite mid-sprint.
Estimate work in story points or hours: Assign a numeric value to each item. Most scrum teams use story points on a Fibonacci scale (1, 2, 3, 5, 8, 13), where a "5" typically represents roughly half a day's work for one developer. Hours work too, but pick one unit and stick to it across the sprint. Mixing both is a common mistake that makes the chart unreadable.
Calculate total work at sprint start: Add up all story point or hour estimates. This single number becomes the Y-axis starting point on your chart. For a two-week sprint with five developers, a typical starting total falls somewhere between 80 and 120 story points, depending on velocity.
Set your sprint duration on the X-axis: Mark each working day from day one to the final day of the sprint. Exclude weekends and any planned holidays now, not later. A 10-day sprint gets 10 data points on the X-axis.
Draw the ideal burndown line: Connect the starting total (top-left) to zero (bottom-right) in a straight diagonal line. This is your reference. Every real data point you plot will be measured against it. The ideal line assumes work burns down at a perfectly even rate, which never actually happens — but it gives you an honest benchmark for burndown chart sprint planning conversations.
Log actual remaining work each day: At the end of each working day, subtract completed story points from the remaining total and plot the new number. Do this daily without exception. Teams that update the chart every two or three days lose the early warning signal that makes sprint progress tracking useful. If your actual line goes flat for two consecutive days, that's a signal worth acting on immediately — diagnose why your actual line has gone flat before it costs you the sprint.
A few practical notes on the build itself. Use a shared spreadsheet or your project management tool so the whole team sees the same data. Whoever marks tasks complete should also update the remaining work total — don't make it the scrum master's job alone. And keep the chart visible during your daily standup. A chart nobody looks at is just a spreadsheet with a graph attached.
Three patterns show up repeatedly in sprint progress tracking, and each one calls for a different response.
Actual line running below the ideal line means your team is burning down work faster than planned. That sounds like good news, but check whether story points were re-estimated downward mid-sprint or whether scope was quietly dropped. If the work genuinely got done, note what the team did differently and carry that into the next sprint's planning session.
Actual line running above the ideal line is the pattern most teams dread. Remaining work is higher than it should be at that point in the sprint. The first question is whether this is an estimation problem or a capacity problem. If two or three people hit blockers on the same day, the line spikes but can recover. If the line has been above ideal since day two, the sprint goal is likely at risk and you need to have that conversation with stakeholders now, not at the retrospective.
A flat line is the most actionable signal. When the chart stops moving for more than a day, work isn't being completed or isn't being logged. Both are problems. Diagnose why your actual line has gone flat before assuming it's a tooling issue. Usually it points to a blocked dependency or unclear task ownership.
Reading these patterns is only useful if you act on them the same day you see them. According to getdx.com, the sprint burndown chart reflects the relationship between remaining work and time left in real time, which means a 24-hour delay in response is a 24-hour delay in recovery.
To view sprint health alongside workload and risk data in one place, you need more than a static chart.
Both charts track sprint progress, but they answer different questions. A burndown chart asks "how much work is left?" A burnup chart asks "how much work is done, and has scope changed?"
Burndown charts count down from total work to zero; burnup charts start at zero and climb toward a moving scope line. That structural difference drives when each one is useful.
Dimension | Burndown chart | Burnup chart |
|---|---|---|
Scope changes mid-sprint | Hides them (line just shifts) | Exposes them visibly as a scope line jump |
Stakeholder communication | Shows urgency and deadline pressure | Shows progress and scope growth side by side |
Mid-sprint clarity | Faster to read at a glance | Requires reading two lines simultaneously |
Setup complexity | Lower — one data series | Higher — two data series to maintain |
For most fixed-scope sprints, the burndown chart wins on simplicity. You set up your sprint scope and task list once, then track daily. If your sprint scope shifts regularly — due to stakeholder requests or discovered dependencies — a burnup chart makes those changes visible instead of burying them in a recalculated ideal line.
For an agile project management chart that needs to serve both your team and external stakeholders, consider running both in parallel during high-change sprints. The overhead is real, but so is the clarity.
Most burndown chart problems don't come from the chart itself. They come from four repeatable errors that distort what the chart shows.
Updating the chart in batches, not daily: When teams log completed work every few days, the actual line drops in cliffs instead of steadily. You lose the early-warning signal the chart exists to provide.
Counting tasks as done before they're done: Marking a story "complete" when it's in review, not accepted, inflates progress. By the time the error surfaces, you're two days from sprint end with no room to adjust.
Ignoring scope changes mid-sprint: Adding or removing stories without adjusting the ideal line makes how to read a burndown chart meaningless. The ideal line no longer reflects reality, so any deviation looks normal. As linearb.io notes, release burndowns become increasingly misleading when requirements evolve.
Starting with a poorly scoped sprint: If you didn't set up your sprint scope and task list carefully before day one, the agile burndown chart is tracking noise from the start.
Manual chart updates fail for a simple reason: the discipline required to maintain them daily competes directly with the sprint itself. When a task slips or scope shifts mid-sprint, the chart rarely reflects it until the next standup, if then.
Taro removes that dependency. Because it pulls live task data into your agile project management chart automatically, the burndown updates when work updates. You can diagnose why your actual line has gone flat without reconstructing what happened from memory.
A burndown chart only works if it reflects reality — and reality changes daily. The gap between your ideal line and actual progress isn't just a number; it's your early warning system for scope creep, blocked dependencies, and capacity mismatches that kill sprints. When you spot a flat line or a drift above ideal on day three instead of day nine, you have time to act.
The friction most teams hit isn't reading the chart — it's keeping it updated. Taro's sprint feature builds and updates your burndown chart automatically as tasks move through status, so the chart reflects what's actually happening without anyone remembering to log it.

Q. How do I create an agile burndown chart?
A. Define sprint scope, estimate work in story points or hours, calculate total work, set sprint duration on the X-axis, draw an ideal diagonal line from total work to zero, then log actual remaining work daily by subtracting completed points from the total.
Q. What is the purpose of a burndown chart in agile project management?
A. It shows whether your team is on track to finish the sprint before time runs out, giving you early warning signals about blockers, scope issues, or capacity problems so you can act mid-sprint, not at the retrospective.
Q. How does a burndown chart help with sprint planning?
A. Your previous sprint's chart reveals blocking patterns and capacity mistakes. If your actual line stayed flat for two days, address that before committing to the next sprint's scope instead of repeating the same failure.
Q. What are the limitations of using a burndown chart?
A. A flat line can mean either blocked work or under-logged work — the chart alone can't tell you which. You need workload and risk data alongside it to diagnose the real problem and apply the right fix.
Q. How can I use a burndown chart to track team progress?
A. Update it daily without exception. A chart updated every three days is history. Daily updates let you catch a flat-line pattern on day two and act immediately, turning it into an early warning system instead of a status report.
Q. What is the difference between a burndown chart and a burnup chart?
A. A burndown chart shows remaining work declining toward zero; a burnup chart shows completed work rising toward the total. Burnup is better for scope-change projects; burndown is clearer for fixed-scope sprints.
Q. How often should you update a burndown chart during a sprint?
A. Daily, at the end of each working day. Teams that update every two or three days lose the early warning signal. A two-day flat line is actionable; by day five, it's too late to recover the sprint.
