Short answer: a Lava Gecko earns $180 per second at its base weight of 14 kg with no mutations. That is $648K per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Lava Gecko at twice the base weight (28 kg) earns $690/s. Type your own Lava Gecko's weight and mutations below.

Lava Gecko income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 14 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 14 kg | ×1.00 | $180 | $648K |
| 2× | 28 kg | ×1.53 | $276 | $993.6K |
| 5× | 70 kg | ×2.70 | $485.63 | $1.75M |
| 10× | 140 kg | ×4.14 | $744.63 | $2.68M |
| 50× | 700 kg | ×11.16 | $2.01K | $7.23M |
| 125× | 1,750 kg | ×19.64 | $3.53K | $12.73M |
| 250× | 3,500 kg | ×25.91 | $4.66K | $16.79M |
Lava Gecko income by mutation
At base weight (14 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 | $180/s | same |
| Silver | $216/s | same |
| Golden | $450/s | same |
| Rainbow | $630/s | same |
| Golden + Bloom | $495/s | $562.5/s |
| Rainbow + Parasite | $990/s | $1.89K/s |
Worked example: a Golden Lava Gecko at twice base weight
- Weight ratio: 28 kg ÷ 14 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $180 × 1.5333 × 2.5 = $690/s, which is $2.48M per hour.
- Saving for the Flame Treadmill ($250K) from $0 with only this pet: 6m 02s. A plain Lava Gecko at base weight would take 23m 08s.
Common mistakes
- Expecting income to double with weight. A Lava Gecko at 28 kg earns $276/s, not double the base. To double its income it has to weigh about 3.08 times the base: 44 kg.
- Forgetting the 125× soft cap. For a Lava Gecko that is 1,750 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 Gecko at base weight earns $495/s if mutations add (the wiki calculator's rule) and $562.5/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.
