Burndown Chart Calculator
Track sprint progress using story points. This burndown chart calculator helps you estimate your current burndown speed, the required pace to finish on time, and visualizes ideal vs actual remaining work.

Sprint details
Working days in the sprint.
Sum of story points planned for the sprint.
Story points burnt each day
Enter burn per day (only the first 5 days are used).

Story points burnt

Current burndown speed

Current = burnt ÷ days since start
Required burndown speed
7.00 pts/day
Required = (total − burnt) ÷ (duration − days since start)
Burndown chart
The chart plots remaining story points against sprint day. The ideal line assumes a steady burn.
You are behind: required burndown speed is higher than the current speed.
Daily burn inputs should be non-negative (story points cannot be negative).
Burndown chart calculation (explained)
In Scrum, teams plan a sprint with a fixed amount of work (often estimated in story points). A burndown chart helps you answer two practical questions:
- How fast are we completing work so far?
- How fast do we need to go to finish by the end of the sprint?
Key formulas
Current speed = burnt ÷ days since startRequired speed = (total − burnt) ÷ (duration − days since start)If required speed is higher than current speed, you’re likely behind. If it’s lower, you’re generally on track (assuming scope stays stable).
How to use this calculator
- Enter sprint duration in working days (e.g., 10).
- Enter total story points planned for the sprint.
- Enter how many days have passed since the sprint started.
- Choose an input method:
- Cumulative progress: enter total burnt points so far.
- Daily burn: enter story points burnt each day for the elapsed days.
- Review current vs required speed and the burndown chart visualization.
Burndown chart example
Current speed
15 ÷ 5 = 3 pts/day
Required speed
(35 − 15) ÷ (10 − 5) = 4 pts/day
In this example the team needs to increase pace (or reduce scope) to finish on time.
