Steal an Egg Income Calculator

Choose a pet, its color mutation and how heavy it hatched, and get its estimated money per second. It uses the same formula the community wiki documents.

How the income formula works

Every pet has a hidden base weight. Divide the weight shown on its card by that base to get the weight ratio, then:

ratio ≤ 125: $/s = base × ratio^(37/60) × mutation
ratio > 125: $/s = base × ratio^(2/5) × 125^(13/60) × mutation

What the wiki says

Stacking Mutations and Sizes

A pet's weight has a major effect on final income, since size rolls are easier to obtain than rare color mutations.

Final income is calculated by multiplying the base rate by both the color multiplier and the size multiplier:

Final Income = Base Income × Mutation(s) Multiplier × Size Multiplier

To be more specific, each pet has a hidden base weight that correlates with their base income. Any pet under 125x the base weight is valued using this formula:

Money/s= Base Value (Actual Weight/Base Weight)^37/60 Mutation Multiplier(s)

Once a pet is above 125x the secret base weight, the game begins to apply diminishing returns. The formula is as follows:

Money/s= Base Value Mutation Multiplier(s) (Actual Weight/Base Weight)^2/5 125^13/60

This is a complex way to say that when you hatch an egg 100x base weight, you'll get ~17x base value, at 200x base weight it'll be ~23x and at 1000x base weight it'll be ~45x base value. The bigger eggs still continue to be worth more but the gain per kg becomes smaller and smaller.

Combination examples: - Normal: $100/s (base, no mutation) - Golden + Giant: 100 × 2.5 × 3 = $750/s (x7.5 total) - Rainbow + Huge: 100 × 3.5 × 5 = $1,750/s (x17.5 total)

No mutation. Notice how slowly income grows past the 125× point.

Mutation multipliers

Mutation multipliers
Mutation	Multiplier	How to get it
Rainbow	×3.5	Animated rainbow effect that continuously changes colors. Extremely rare hatch roll — roll weight 1 out of 100.
Parasite	×3	Not obtainable through normal hatch rolls. Comes from its own dedicated Parasite Egg, obtained through the feeding event.
Fractured	×2.75	Not obtainable through normal hatch rolls. Can be applied to an egg with a Mutation Consumable for a 10% chance.
Scrambled	×2.75	Poison like effect. Currently obtainable via Dr. Scramble's Shop — can be applied to an egg with a 10% chance.
Golden	×2.5	Shiny metallic gold texture with coin particles. Roll weight 4 out of 100.
Spirit Bloom	×2.5	Green spiritual effect. Currently unobtainable via normal roll — obtained instead through the Sakura Incubator.
Bloom	×1.25	Cherry blossom petal particles. Likely gated behind the Sakura event rather than normal hatching.
Silver	×1.2	Shiny silver appearance with metallic reflections. Roll weight 6 out of 100.
