- Union perfect stats: 6/6
- Inherited stat probability: 83.3%
- Per-stat perfect chance: 83.85%
- Nature/Ability/Shiny modifiers are multiplied into final odds.
Formula Assumption
IV distribution uses an independence approximation for quick planning. Use simulator-grade tools for exact edge-case breeding trees.
Formulas Used
p(parent perfect on stat) = (p1 + p2 - shared) / 6
p(stat perfect) = p(inherited) x p(parent perfect) + (1-p(inherited)) x 1/32
p(IV target) = Sum[C(6,i) x p^i x (1-p)^(6-i)] for i=target..6
p(all targets) = p(IV target) x p(nature) x p(ability) x p(shiny)
FAQ
Does this require Destiny Knot?
No, but enabling it significantly improves high-IV target odds.
Should shiny chance be included?
Include it only if your goal is perfect-egg plus shiny in the same hatch target.
Can this replace exact breeding simulators?
It is designed for fast planning and rough expectation, not exact combinatorial path simulation.

Pokemon Breeding Odds Calculator FAQ
How do Destiny Knot and Everstone affect odds?
Destiny Knot passes five IVs from parents, while Everstone locks the nature from the holding parent.
Can this estimate shiny odds too?
Yes. Use your chosen method and charm bonuses to include shiny probability in the egg plan.
How many eggs should I expect?
The calculator estimates expected egg counts based on your target combination and the selected odds.
