What is sprint capacity planning?
Sprint capacity planning is the process of determining how much work your team can realistically complete in a single sprint. It factors in team size, individual availability (accounting for meetings, leave, and support tasks), working hours, and historical velocity so you commit to a realistic workload rather than over- or under-promising.

How is sprint capacity calculated?
Sprint Capacity (story points) = Team Size × (Availability % / 100) × Sprint Working Days × Hours per Day × Velocity. For example, a 6-person team at 75% availability over 10 days at 8 hours/day with 0.5 story points/hour yields 180 story points of raw capacity. Subtract your buffer to get your safe planning capacity.
What is a good availability percentage to use?
Most agile teams use 70–80% availability to account for daily stand-ups, backlog refinement, code reviews, ad-hoc support, and other non-feature work. If your team has unusually heavy meeting loads or cross-team obligations, 60–70% may be more realistic.
Why should I include a buffer in sprint planning?
A buffer (typically 15–20% of total capacity) is held back to absorb unplanned work such as urgent bug fixes, sick days, or unexpected blockers. Planning to 100% of capacity almost always leads to spillover and reduces team morale. A 20% buffer is the most commonly recommended starting point.

How do I calculate team velocity?
Team velocity is the average number of story points your team completes per hour of focused work. To find it, divide the total story points completed in past sprints by the total available focused hours in those sprints. Using an average of the last 3–5 sprints gives a more stable baseline than relying on a single sprint.
What sprint duration is best for my team?
Two-week sprints are the most common choice and provide a good balance between planning overhead and feedback frequency. One-week sprints suit fast-moving teams or early-stage products needing rapid validation. Three- or four-week sprints may work for teams with complex, slower-moving features, but they risk reduced agility.
How does the sprint end date get calculated?
The calculator adds the number of working days for your chosen sprint duration to the start date, automatically skipping weekends. For a 2-week sprint starting on Monday, you'll end on the Friday of the second week — 10 working days later.
What is the difference between sprint capacity and safe planning capacity?
Sprint capacity is the total story points your team could theoretically complete based on available hours and velocity. Safe planning capacity subtracts your buffer reserve from that total, giving you the number of story points you should actually commit to in the sprint. Committing to the safe capacity protects the team from chronic overcommitment.
