Burndown Chart — Smart Financial Analysis
Spotify runs 100+ squads simultaneously — and each one uses burndown charts to stay on track. Here's how to master yours.
Did our AI summary help? Let us know.
A burndown chart visualizes remaining work over time — the most important agile/scrum progress tool. Scrum teams use burndown charts to track sprint progress. Burndown shows work remaining (line goes down). The ideal burndown line is a straight diagonal from total work at day 0 to zero at the sprint end.

A burndown chart visualizes remaining work over time — the most important agile/scrum progress tool. The ideal burndown line shows a steady decline from total work to zero. When actual work is ABOVE the ideal line → behind schedule. BELOW → ahead. Scrum teams typically run 2-week sprints with velocity (story points completed/sprint) tracked over time. Average team velocity stabilizes after 3-4 sprints. The chart exposes risks early: if day 5 of a 10-day sprint shows 70% remaining, the team needs to adjust scope, add resources, or extend. 82% of agile teams use burndown charts.
📈 By the Numbers
📋 Key Takeaways
- • Ideal burndown = straight line from total to zero
- • Actual above ideal = behind schedule; below = ahead
- • Velocity = story points completed per sprint; track 3+ sprints
- • Scope creep shows as the line going UP instead of down
📐 How It Works
- Ideal Rate: Total Points ÷ Sprint Duration (100 pts ÷ 10 days = 10 pts/day)
- Velocity: Completed Points ÷ Days Worked
- Projected Completion: Remaining Points ÷ Velocity
- Release Burndown: Track remaining across sprints; avg velocity predicts release date
💡 Expert Tips
- Track velocity over 3+ sprints before committing to forecasts.
- When actual rises above ideal, run a standup to identify blockers.
- Use burn-up charts when scope changes frequently.
- Keep sprint scope fixed; if you add work, remove something of equal size.
📊 Sprint Metrics Dashboard
| Metric | Description | Healthy Range |
|---|---|---|
| Velocity | Story points completed per day | Stable across 3+ sprints |
| Sprint Health | Actual vs ideal burndown | Actual at or below ideal |
| Scope Creep | Work added mid-sprint | Zero — scope locked |
| Completion % | Progress toward sprint goal | On track for 100% by end |
❓ Frequently Asked Questions
What is a burndown chart?
A burndown chart visualizes remaining work over time — the most important agile/scrum progress tool. The Y-axis shows work remaining (story points or tasks); the X-axis shows time (sprint days). The ideal line declines steadily from total work to zero. When actual work is ABOVE the ideal line you're behind schedule; BELOW means ahead.
How is a burndown chart used in Agile and Scrum?
Scrum teams use burndown charts to track sprint progress. Typically 2-week sprints with velocity (story points completed per sprint) tracked over time. The chart exposes risks early: if day 5 of a 10-day sprint shows 70% remaining, the team needs to adjust scope, add resources, or extend. 82% of agile teams use burndown charts.
What is the difference between burndown and burn-up charts?
Burndown shows work remaining (line goes down). Burn-up shows work completed (line goes up). Burn-up is better when scope changes mid-sprint because added work is visible as the total scope line rises. Burndown can be confusing when scope creep occurs — the line may go up instead of down.
What is the ideal burndown line?
The ideal burndown line is a straight diagonal from total work at day 0 to zero at the sprint end. Slope = Total Points ÷ Sprint Duration (e.g., 100 pts in 10 days = 10 pts/day). When actual dips below ideal you're ahead; when it rises or flattens, investigate blockers or scope creep.
What is a sprint burndown chart?
A sprint burndown chart tracks remaining work within a single sprint (usually 1–2 weeks). It compares ideal progress (straight line) to actual progress (lumpy line). Velocity = completed points ÷ days worked. Average team velocity stabilizes after 3–4 sprints for reliable forecasts.
What is a release burndown chart?
A release burndown chart tracks remaining work across multiple sprints toward a release. It shows total story points remaining vs sprint number. Average velocity (e.g., 50 pts/sprint across 10 sprints for 500 pts) determines when the release will complete. Used for release planning and forecasting.
