How Story Points Are Calculated
The estimator uses a combination of rules and a nonlinear formula to map your slider choices to Fibonacci story points:
- Both Unknowns & Dependencies at 5: Minimum 21 points
- Business Logic Complexity or Technical Implementation Difficulty at 5: Minimum 13 points
- All sliders at 3: 5 points (average story)
- All non-inverse at 1, inverse at 5: 1 point (minimum)
- All non-inverse at 5, inverse at 1: 34 points (maximum)
- Unknowns or Dependencies at 5: Minimum 8 points
- Otherwise: A nonlinear formula blends all factors for a smooth transition between Fibonacci values.
High risk, uncertainty, or complexity will sharply increase the estimate, while low values across all factors produce the lowest story points.
