King Snake Income Calculator
For the Roblox game Steal An Egg. Type your King Snake'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 King Snake earns $3.5M per second at its base weight of 10,000 kg with no mutations. That is $12.6B per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden King Snake at twice the base weight (20,000 kg) earns $13.42M/s. Type your own King Snake's weight and mutations below.

King Snake income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 10,000 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 10,000 kg | ×1.00 | $3.5M | $12.6B |
| 2× | 20,000 kg | ×1.53 | $5.37M | $19.32B |
| 5× | 50,000 kg | ×2.70 | $9.44M | $33.99B |
| 10× | 100,000 kg | ×4.14 | $14.48M | $52.12B |
| 50× | 500,000 kg | ×11.16 | $39.06M | $140.63B |
| 125× | 1,250,000 kg | ×19.64 | $68.73M | $247.44B |
| 250× | 2,500,000 kg | ×25.91 | $90.69M | $326.5B |
King Snake income by mutation
At base weight (10,000 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 | $3.5M/s | same |
| Silver | $4.2M/s | same |
| Golden | $8.75M/s | same |
| Rainbow | $12.25M/s | same |
| Golden + Bloom | $9.63M/s | $10.94M/s |
| Rainbow + Parasite | $19.25M/s | $36.75M/s |
Worked example: a Golden King Snake at twice base weight
- Weight ratio: 20,000 kg ÷ 10,000 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $3.5M × 1.5333 × 2.5 = $13.42M/s, which is $48.3B per hour.
- Saving for the The Freeze Treadmill ($3B) from $0 with only this pet: 3m 43s. A plain King Snake at base weight would take 14m 17s.
Common mistakes
- Expecting income to double with weight. A King Snake at 20,000 kg earns $5.37M/s, not double the base. To double its income it has to weigh about 3.08 times the base: 30,773 kg.
- Forgetting the 125× soft cap. For a King Snake that is 1,250,000 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 King Snake at base weight earns $9.63M/s if mutations add (the wiki calculator's rule) and $10.94M/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.
