Breeding championship-ready Pokémon just got easier! Whether you're using a Pokémon breeding calculator to predict IVs, a Pokémon ability calculator to track Hidden Abilities, or a Pokémon egg move calculator to plan inheritance, this guide reveals the science behind creating perfect Pokémon.

How Breeding Calculators Work

IV Inheritance Formula

When using Destiny Knot, the game selects:

5 IVs from both parents combined (randomly chosen)
1 IV randomly generated (0-31)

Probability of 6 Perfect IVs:

(6/6 parents' IVs) × (1/32) = 1/32 chance  
(5/6 parents' IVs) × (1/32) = 1/48 chance

Shiny Odds Formula (Masuda Method)

Base Rate: 1/4096  
+ Masuda Method: 1/683  
+ Shiny Charm: 1/512

Tool Type	What It Calculates	Best For

Shiny Calculator	Masuda Method odds	Shiny hunting

Step-by-Step Breeding Optimization

1. IV Inheritance (Destiny Knot Method)

Parent A (6IV Ditto) + Parent B (5IV Target)
Expected outcomes:
- 31/X/31/31/31/31 (X = random)
- 31/31/31/31/31/X

Pro Tip: Use our recommended Pokémon Showdown Team Builder to test IV spreads before breeding!

2. Nature & Ability Control

Item	Effect	Success Rate
Everstone	Guarantees Nature	100%
Ability Patch	Forces Hidden Ability	100%

3. Egg Move Inheritance

Father must know the move
Same Egg Group required
Example:
- Male Lucario (Bullet Punch) + Female Lucario
- Offspring Riolu will inherit Bullet Punch

FAQs

1. Which Pokémon Ability Calculator is most accurate?

Standard vs Hidden Ability odds
Genderless breeding exceptions

2. How do Egg Move Calculators handle cross-gen differences?

Scarlet/Violet vs Sword/Shield compatibility
Removed moves (e.g., Pursuit in Gen 8+)

3. Can calculators predict shiny Pokémon with sandwiches?

No - sandwich boosts (Gen 9) affect wild encounters only, not breeding odds. Masuda Method remains separate.

Advanced Breeding Formulas

Probability of Specific IV Spreads

Chance of 5 perfect IVs (with 6IV + 5IV parents):
(5 choose 5) × (1/6) × 31/32 = ~5.2% per egg

Egg Cycle Calculation

Total Steps = Egg Cycles × 256  
Flame Body cuts this in half (e.g., 512 → 256 steps)
