Burndown Chart Calculator
Track sprint progress and calculate burndown speeds for Agile project management
Sprint Details
Total number of working days in the sprint
Sum of all story points in the sprint
Number of working days completed
Total story points completed so far
Daily Story Points Burnt
Burndown Analysis
Formulas used:
Current Speed = Story Points Burnt ÷ Days Since Start
Required Speed = Remaining Points ÷ Remaining Days
Completion % = (Points Burnt ÷ Total Points) × 100
Recommendations
Example: Team Alpha Sprint
Sprint Setup
Team: Team Alpha
Sprint Duration: 2 weeks (10 working days)
Total Story Points: 35
Days Completed: 5 working days
Story Points Burnt: 15
Burndown Analysis
Current Speed: 15 ÷ 5 = 3 points/day
Required Speed: (35 - 15) ÷ (10 - 5) = 4 points/day
Status: Behind schedule - need to increase velocity
Agile Concepts
Sprint
Time-boxed iteration, typically 1-4 weeks
Story Points
Relative measure of effort and complexity
Velocity
Rate of story point completion over time
Burndown Tips
Update burndown daily for accurate tracking
Focus on completed work, not work in progress
Use trends to predict sprint completion
Address velocity issues early in sprint
Understanding Burndown Charts
What is a Burndown Chart?
A burndown chart is a graphical representation of work left to do versus time in an Agile sprint. It shows the team's progress in completing tasks and helps predict whether the sprint goal will be achieved.
Key Components
- •X-axis: Sprint days (time progression)
- •Y-axis: Story points remaining
- •Ideal line: Perfect completion trajectory
- •Actual line: Real progress tracking
Burndown Speed Formulas
Current Speed = Points Burnt ÷ Days Elapsed
Required Speed = Remaining Points ÷ Remaining Days
Completion % = (Points Burnt ÷ Total Points) × 100
Benefits
- •Visual progress tracking
- •Early risk identification
- •Team velocity measurement
- •Sprint completion prediction
Interpreting Your Burndown
Good Signs
- • Steady downward trend
- • Actual line near ideal line
- • Consistent daily progress
- • Team meeting velocity goals
Warning Signs
- • Flat or increasing trend
- • Large gap from ideal line
- • Irregular progress patterns
- • Consistently missing targets
