What Does the Pet Mutation Calculator Do?

This calculator is divided into two main parts:

1. Mutation Effects

• Shows how a mutation changes:
• XP gain
• Hunger rate
• Passive abilities
• Displays before vs after comparison
• Helps you choose the best mutation for your playstyle

2. Probability Calculator

• Calculates:
• Chance of getting a mutation
• Probability of at least one success
• Exact success scenarios (binomial probability)
• Useful for planning upgrades when you have multiple pets

Mutation Formula Explained

The calculator uses the following logic:

XP Calculation

XP After = Base XP × (1 + XP% Bonus) + Flat XP Bonus

Hunger Calculation

Hunger After = Base Hunger × (1 + Hunger%)

Passive Ability

Passive After = Base Passive × (1 + Passive%)

Probability Formula

P(X = k) = C(n, k) × p^k × (1 − p)^(n − k)

Where:

• n = number of pets
• p = mutation probability
• k = desired successes

Example Calculation

Let’s say:

• Base XP = 10/sec
• Mutation = Shiny (+15% XP)
• Pet count = 5

Result:

XP After = 10 × (1 + 0.15) = 11.5 XP/sec

Total XP = 11.5 × 5 = 57.5 XP/sec

Probability Example:

• Mutation chance = 30%
• Pets = 10

At least one success = 1 − (1 − 0.3)^10 ≈ 97.2%

This means you almost guarantee at least one mutation.

How to Use the Calculator

Step-by-Step:

1. Select a mutation (e.g., Shiny, Rainbow, Golden)
2. Enter your base stats:

• XP per second
• Hunger rate
• Passive abilities

1. Adjust pet count
2. Click Calculate Effects
3. Switch to Probability Calculator tab
4. Enter number of pets to estimate chances

• Instant results (no download required)
• Accurate mutation effect breakdown
• Advanced probability calculations
• Works for all pet types and builds
• Helps create best grow a garden pet tier list

If you're serious about optimizing pets, this tool replaces manual calculations completely.

Below is a complete overview of all major pet mutations, including their effects, rarity, and probability. This helps you quickly compare and decide which mutation is best for your build.

Best Mutations Tier List (Pet Mutation Ranking Guide)

Choosing the right mutation depends on your goal — XP farming, passive builds, or rare bonuses. Here’s a complete Grow a Garden pet mutation tier list:

S Tier (Best Overall – Must Have)

• Cosmic – Massive XP + passive boost (top-tier mutation)
• Void – Extremely strong passive scaling
• Ascended – Unique fruit generation ability
• Celestial – Best for XP-focused builds

Best for: Endgame players & max optimization

A Tier (High Value Mutations)

• Rainbow – Strong passive boost
• Golden – Reliable all-round passive upgrade
• Dawnbound – Great synergy with rare fruits
• Corrupt – High passive scaling

Best for: Advanced builds & hybrid setups

B Tier (Situational but Useful)

• Inverted – Great XP boost early game
• Shiny – Solid and consistent XP gain
• Disco – Good event-based utility
• Mega – High output but increases hunger

Best for: Mid-game progression

C Tier (Niche / Early Game)

• Tiny – Useful for efficiency builds
• Frozen – Limited use, depends on setup

Best for: Specific strategies only

How to Choose the Best Mutation

• XP Farming → Celestial, Cosmic, Inverted
• Passive Builds → Void, Rainbow, Golden
• Balanced Setup → Shiny + Golden
• Rare Utility → Ascended, Dawnbound
