Calculate team capacity with sprint velocity, planned time off, and buffer allocation for accurate sprint/iteration planning.
Sprint velocity alone can overstate what a team should plan when the next iteration includes vacations, holidays, training, or expected interruptions. This calculator combines a velocity baseline with planned time off and a reserved buffer to produce an adjusted sprint capacity. The result remains in the same work unit as the entered velocity. A common mistake is treating velocity as staff-hours: if velocity is measured in story points, the calculated capacity is also expressed in story points, not hours.
Enter the sprint velocity that represents the team's completed work in its established unit, such as story points or another consistently tracked measure. This value provides the starting capacity for the iteration. A velocity drawn from several comparable sprints is generally more representative than a single unusually productive or disrupted sprint.
Planned time off reduces the availability represented by the velocity baseline, while buffer allocation reserves part of the remaining capacity for interruptions or unplanned work. The calculator reports the resulting amount available for planned sprint work. Keep time-off and buffer assumptions separate so that the same expected absence or interruption is not deducted twice.
Use the unit in which the team actually records completed sprint work, and interpret the output in that same unit. Story points are suitable when the velocity history is in story points; hours are suitable only when the baseline is genuinely tracked in hours. The calculator does not make story points and hours interchangeable.
No. It is a planning figure based on the supplied velocity, time-off assumptions, and buffer. It cannot account for every dependency, production incident, estimation error, or change in team composition. Use it to size a plausible workload, then review the selected work against current risks and the team's judgment during sprint planning.
