About Sprint Velocity Calculator
Track and analyse your team's sprint velocity over time. Enter the number of story points completed in each sprint (one per line) and the tool calculates the average velocity, median, minimum, maximum, and standard deviation. It also suggests a conservative capacity for the next sprint by subtracting one standard deviation from the average — a commonly used safety buffer for sprint planning.
How to use
- Enter the story points completed in each sprint, one number per line.
- Click Convert to calculate velocity statistics.
- Use the suggested capacity as a baseline for your next sprint planning session.

Frequently Asked Questions
FAQs about Sprint Velocity Calculator
What is sprint velocity?
Sprint velocity is the amount of work (measured in story points) a team completes during a single sprint. Tracking velocity over multiple sprints helps teams predict how much work they can commit to in future sprints.
How many sprints should I use to calculate velocity?
Most teams use the last 3 to 5 sprints for a rolling average. Using too few sprints can skew the result due to anomalies; using too many may not reflect the team's current capacity.
What is the suggested capacity used for?
The suggested capacity (average minus one standard deviation) is a conservative estimate for sprint planning. It builds in a safety buffer to account for variability and reduce the risk of over-committing.
Why does standard deviation matter for velocity?
A high standard deviation means your team's output varies significantly sprint to sprint, making planning harder. A low standard deviation indicates a stable, predictable team rhythm.
