Planet RoadmapSprint Burndown Chart Generator
Enter your sprint's total committed points and remaining points by day. We render the chart with the ideal line, flag if you're behind, and let you export the data.
How the chart works
The ideal line is a straight slope from your total committed points down to zero at the last day. The actual line is whatever you enter. We mark the sprint as "behind" if the final day's remaining points exceed the ideal value at the same point.
Frequently asked questions
What is a burndown chart?
A burndown chart shows how much work remains in a sprint, day by day. The x-axis is the days of the sprint, the y-axis is remaining story points (or hours). The actual line is what your team has left; the ideal line is a straight diagonal from total committed points down to zero.
How do I read a burndown chart?
If your actual line stays below the ideal line, you are tracking ahead of plan. If it sits above, you are behind — you committed more than you can finish at the current pace. A flat actual line means nothing got completed that day; a vertical drop means a chunk of work shipped at once.
What is the ideal line?
The ideal line is a straight slope from total committed points at day 0 down to zero on the last day. It assumes work burns down evenly, which never quite happens in practice — but it is a useful baseline to spot when a sprint is drifting.
Should I update the chart daily?
Most teams update once a day, typically right after the daily standup. Updating less than once a day makes the chart slow to surface trouble; updating more often is unnecessary noise.
What if my actual line goes up?
Rising remaining points means scope was added mid-sprint — new tickets, new estimates, or unplanned bugs. This is a strong retrospective topic. Chronic mid-sprint scope creep usually means sprint planning is missing detail or the team is being pulled in by stakeholders.
Is this saved anywhere?
Everything is in your browser via localStorage. The generator works offline and never sends data to a server. Use Export CSV to back up or share.
