Free Pokémon Breeding Calculator – Plan the Perfect Pokémon!

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

Breeding Calculator Tools Comparison

Tool Type	What It Calculates	Best For
IV Calculator	Inherited stats from parents	Competitive breeding
Pokémon Ability Calculator	HA inheritance odds (60% chance)	Hidden Ability hunting
Pokémon Egg Move Calculator	Compatible inherited moves	Special move sets
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)
