Calculate sprint velocity and forecast remaining sprints for a backlog.
Velocity is a measurement rather than a commitment, so forecasting from the observed range is more honest than using the average alone. Three sprints is the usual minimum before the average means anything. Story points are only comparable within a team, so using velocity to compare teams or to set targets destroys the estimate quality it depends on.
Story Point Velocity
Velocity = mean completed points; sprints remaining = backlog ÷ velocity

This calculator takes 5 inputs: Sprint 1 completed points, Sprint 2 completed points, Sprint 3 completed points, Remaining backlog points, Sprint length. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
