Calculator
Pet income calculator
Add the rates shown on your pets to total your pen, including newly released pets with no verified base figure. Published-rate mode is a separate estimate with visible assumptions.

Pet income calculator
Enter the income shown in your game for an exact input-based total, or compare a published base figure using assumed size multipliers. Measured income already includes bonuses; we do not multiply it again.
Published base: community-reported, checked 2026-08-27. Size presets are assumptions.
Mutation multipliers are sourced and listed on the mutations page. The size multipliers here are approximations — the game confirms bigger pets earn more but does not publish the exact curve, so treat the size slider as a rough comparison rather than an exact figure.
Try a pen total without guessing a base rate
This reproducible example uses hypothetical readings, not a tested pet lineup. Enter 1200 in “Measured income per second”, add a second pet with 800, then a third with 500. The pen total is $2,500/s, or $150,000 per minute if all three rates stay unchanged and earnings accumulate for that full minute.
Suppose the first pet's $1,200/s display already reflects its mutation and size. Enter 1200 once; do not multiply it by Golden or move the size slider to reproduce the same bonus. Those controls disable while a measured reading is present. Selecting a different pet clears the reading, so re-enter the value that belongs to the replacement.
Replace an occupied slot: count only the gain
Change the third reading from 500 to 1400. Your new total is $3,400/s; the improvement is $900/s, because the old $500/s stops earning. Adding $1,400/s to the previous total would incorrectly count both pets in one occupied slot. Keep the same number of rows when comparing a replacement.
| Decision | Reproducible calculation | Result |
|---|---|---|
| Keep the three readings | 1,200 + 800 + 500 | $2,500/s |
| Replace the $500/s slot | 1,200 + 800 + 1,400 | $3,400/s, a $900/s gain |
| Recover a hypothetical $36,000 replacement cost | 36,000 ÷ 900 | 40 seconds at unchanged rates |
| Reach $400,000 from $100,000 without replacing | (400,000 − 100,000) ÷ 2,500 | 120 seconds |
| Pay $36,000 now, then reach $400,000 | (400,000 − 64,000) ÷ 3,400 | About 98.8 seconds |
The 40-second recovery compares the extra income with the purchase cost. It is not the wait to reach the cash target. The 98.8-second plan assumes you already have the replacement available, can afford it, and lose no earning time during the swap. Acquisition time, a missing input, a changed bonus or a separate purchase can change the choice. No hatch probability or pet resale value is inferred from these rates.
An active one-minute projection is not an offline payout promise. This calculator totals rates, without modeling offline caps, collection rules or server resets. If any pet has an unknown base and no reading, the displayed amount is a known subtotal; it is not a complete pen forecast. Use the measured-rate planning guide for a checklist and a two-stage Speed example.
What the published income spread can tell you
Published figures help identify pets to compare with your own readings. Kitsune has the highest listed base in this sample at $1.8B/s, but its record is unconfirmed and some newer pets have no published income. A large listed figure does not establish how likely you are to obtain that pet, what it would earn at your size, or whether it improves your occupied slot.
Mutation multipliers
| Mutation | Multiplier | Where it comes from |
|---|---|---|
| Silver | 1.25× | Found on the map, Fuse Machine |
| Bloom | 1.5× | Sakura Incubator — 97.5% roll |
| Golden | 2× | Found on the map, Fuse Machine |
| Rainbow | 2.5× | Found on the map, Fuse Machine |
| Spirit Bloom | 3× | Sakura Incubator — 2.5% – 40% roll |
Full detail, including how the Sakura Incubator odds work, is on the mutations page.
Where this calculator is approximate
Base income and mutation multipliers come from sourced data and are listed with their provenance on the pets page. The size multipliers are not: the game confirms that larger pets earn more but does not publish the curve, so the size slider here is a comparison aid rather than an exact figure. The arithmetic is deterministic, but its accuracy depends on the inputs. Use measured income to bypass both multipliers; never apply them twice to an already boosted reading.
Income FAQ
What is the best pet in Steal An Egg?
Kitsune has the highest published figure in our ranked sample at $1.8B/s, but that base is unconfirmed and newer pets have missing values. This is not a complete ranking of the live game.
How do mutations affect income?
Mutations multiply base income: Silver 1.25×, Bloom 1.5×, Golden 2×, Rainbow 2.5× and Spirit Bloom 3×, the highest multiplier in this calculator; other mutations have unknown multipliers.
Does pet size change how much it earns?
Yes. A pet hatched unusually large earns noticeably more than a standard-sized one of the same species, and that stacks with any mutation. The exact curve is not published.
Is it better to have many cheap pets or one strong one?
Compare actual income per occupied slot. Rarity alone is not a complete ranking, and pets with unknown base values can be compared by entering the rate shown in your game.
