Story Point Calculator
During planning poker each team member independently estimates the complexity of a user story. The Story Point Calculator combines all those estimates into an average, a median, and a suggestion on the Fibonacci scale. You can instantly see whether the team agrees or whether a discussion is still needed.
Story Point Calculator: how does it work?
Enter the estimates of all team members, separated by commas or line breaks. The calculator computes the average and the median. It then finds the nearest value in the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21) — that becomes the suggested score. Finally, a consensus indicator is shown: if all estimates fall within one Fibonacci step of the median, consensus is reached. If the lowest or highest estimate deviates more, those are shown as outliers and the team is prompted to discuss briefly.
Example
Team member A estimates 3, B estimates 5, C estimates 5. Average: (3+5+5)/3 ≈ 4.3. Median: 5. Nearest Fibonacci: 5. One estimate (3) is one Fibonacci step below 5 — that falls within the threshold, so the result is: suggested 5 points, consensus. Had A estimated 2, the gap would have been two steps and the calculator would flag: 'discuss outliers min=2, max=5'.
Frequently asked questions
Why do we use Fibonacci numbers for story points?
The Fibonacci sequence reflects the uncertainty that grows as tasks get larger. The difference between 1 and 2 is smaller than between 8 and 13, so larger estimates are inherently less precise. That is fair: you cannot accurately estimate a large, complex story.
What should I do when the spread is very large?
Ask the two extremes to briefly explain their reasoning: why does the optimist estimate low and the pessimist high? Often you discover a difference in assumption or scope. Re-estimating after that conversation almost always leads to better consensus.
Are story points equal to hours?
No. Story points express relative complexity and effort, not calendar hours. Two teams can complete the same story at different speeds. Use story points to compare stories with each other and track velocity, not to plan hours.
