Sprint Capacity Calculator
Calculate Sprint Capacity step by step: Sprint capacity (points) = average velocity × available person-days ÷ normal person-days.
In short
Formula: Sprint capacity (points) = average velocity × available person-days ÷ normal person-days.
What this calculator does
Calculate Sprint Capacity step by step: Sprint capacity (points) = average velocity × available person-days ÷ normal person-days. Worked example, questions and limitations included.
Use it to turn Average velocity, Normal team person-days per sprint, Available person-days this sprint into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this agile delivery calculation.
Inputs and what they mean
- Average velocity
- — number value.
- Normal team person-days per sprint
- — number value.
- Available person-days this sprint
- — number value.
How to use it
- Enter each value in the unit shown next to the box (use the unit converter first if your numbers are in other units).
- Check the breakdown to see every intermediate step.
- Read the limitations before relying on the result.
Formula
Availability-adjusted velocity ('yesterday's weather') is a common Scrum and XP practice, not a rule of the Scrum Guide.
The team still decides what to pull into the sprint; this is an input to that conversation.
Velocity is specific to one team and its own estimating scale. It is not comparable between teams and is not a productivity benchmark; use it only for that team's own forecasting.
Sprint capacity (points) = average velocity × available person-days ÷ normal person-days.
Inputs used: Average velocity, Normal team person-days per sprint, Available person-days this sprint.
Worked example
Holiday sprint
- 48 ÷ 60 = 80%.
- 23 × 0.8 = 18.4 points.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Assumes velocity scales linearly with availability.
- Team-specific.
- Ignores skill mix.
- Results are planning estimates built only from the figures you enter. They are not a guarantee of cost, schedule or delivery, and they do not replace your organisation's own project controls.
- The result depends on the values you enter for this sprint capacity calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
Common questions
Is this a commitment?
No. It is a forecast to guide planning; the team selects the sprint backlog.
What if a new member joins?
Count their days at a reduced rate while they ramp up. Check the formula, example, and limitations on this page before using the result for a real agile delivery decision.
Can I use this for other teams?
Only with that team's own velocity and days. Check the formula, example, and limitations on this page before using the result for a real agile delivery decision.
How do I use the Sprint Capacity Calculator?
Enter the required values for Average velocity, Normal team person-days per sprint, Available person-days this sprint. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Sprint Capacity Calculator use?
Sprint capacity (points) = average velocity × available person-days ÷ normal person-days. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.
Can the Sprint Capacity Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
