Gorilla King Income Calculator
For the Roblox game Steal An Egg. Type your Gorilla King's weight and mutations to see what it earns and how long it takes to afford your next upgrade.
Updated · game data from the wiki as of 30 September 2026 · changelog
Short answer: a Gorilla King earns $880M per second at its base weight of 100,000 kg with no mutations. That is $3.17T per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Gorilla King at twice the base weight (200,000 kg) earns $3.37B/s. Type your own Gorilla King's weight and mutations below.

Gorilla King income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 100,000 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 100,000 kg | ×1.00 | $880M | $3.17T |
| 2× | 200,000 kg | ×1.53 | $1.35B | $4.86T |
| 5× | 500,000 kg | ×2.70 | $2.37B | $8.55T |
| 10× | 1,000,000 kg | ×4.14 | $3.64B | $13.11T |
| 50× | 5,000,000 kg | ×11.16 | $9.82B | $35.36T |
| 125× | 12,500,000 kg | ×19.64 | $17.28B | $62.21T |
| 250× | 25,000,000 kg | ×25.91 | $22.8B | $82.09T |
Gorilla King income by mutation
At base weight (100,000 kg). With two mutations the wiki disagrees with itself on whether they add or multiply, so both are shown.
| Mutation | If they add | If they multiply |
|---|---|---|
| None | $880M/s | same |
| Silver | $1.06B/s | same |
| Golden | $2.2B/s | same |
| Rainbow | $3.08B/s | same |
| Golden + Bloom | $2.42B/s | $2.75B/s |
| Rainbow + Parasite | $4.84B/s | $9.24B/s |
Worked example: a Golden Gorilla King at twice base weight
- Weight ratio: 200,000 kg ÷ 100,000 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $880M × 1.5333 × 2.5 = $3.37B/s, which is $12.14T per hour.
- Saving for the Hacker Treadmill ($3T) from $0 with only this pet: 14m 49s. A plain Gorilla King at base weight would take 56m 49s.
Common mistakes
- Expecting income to double with weight. A Gorilla King at 200,000 kg earns $1.35B/s, not double the base. To double its income it has to weigh about 3.08 times the base: 307,721 kg.
- Forgetting the 125× soft cap. For a Gorilla King that is 12,500,000 kg. Past it, extra weight still helps but much less: doubling from 125× to 250× adds only about 32%.
- Assuming mutations multiply. A Golden + Bloom Gorilla King at base weight earns $2.42B/s if mutations add (the wiki calculator's rule) and $2.75B/s if they multiply. Plan with the lower number until it's confirmed.
- Counting the x2 gamepass twice. Tick it once. If you copy this pet's income into the treadmill calculator with x2 already included, leave x2 unticked there.
