Lava Dragon Income Calculator
For the Roblox game Steal An Egg. Type your Lava Dragon'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 Lava Dragon earns $100M per second at its base weight of 14,000 kg with no mutations. That is $360B per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Lava Dragon at twice the base weight (28,000 kg) earns $383.33M/s. Type your own Lava Dragon's weight and mutations below.

Lava Dragon income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 14,000 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 14,000 kg | ×1.00 | $100M | $360B |
| 2× | 28,000 kg | ×1.53 | $153.33M | $552B |
| 5× | 70,000 kg | ×2.70 | $269.79M | $971.26B |
| 10× | 140,000 kg | ×4.14 | $413.68M | $1.49T |
| 50× | 700,000 kg | ×11.16 | $1.12B | $4.02T |
| 125× | 1,750,000 kg | ×19.64 | $1.96B | $7.07T |
| 250× | 3,500,000 kg | ×25.91 | $2.59B | $9.33T |
Lava Dragon income by mutation
At base weight (14,000 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 | $100M/s | same |
| Silver | $120M/s | same |
| Golden | $250M/s | same |
| Rainbow | $350M/s | same |
| Golden + Bloom | $275M/s | $312.5M/s |
| Rainbow + Parasite | $550M/s | $1.05B/s |
Worked example: a Golden Lava Dragon at twice base weight
- Weight ratio: 28,000 kg ÷ 14,000 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $100M × 1.5333 × 2.5 = $383.33M/s, which is $1.38T per hour.
- Saving for the Lucky Block Treadmill ($75B) from $0 with only this pet: 3m 15s. A plain Lava Dragon at base weight would take 12m 30s.
Common mistakes
- Expecting income to double with weight. A Lava Dragon at 28,000 kg earns $153.33M/s, not double the base. To double its income it has to weigh about 3.08 times the base: 43,081 kg.
- Forgetting the 125× soft cap. For a Lava Dragon that is 1,750,000 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 Lava Dragon at base weight earns $275M/s if mutations add (the wiki calculator's rule) and $312.5M/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.
