Updated · game data from the wiki as of 30 September 2026 · changelog
Short answer: a Lava Frog earns $850 per second at its base weight of 4 kg with no mutations. That is $3.06M per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Lava Frog at twice the base weight (8 kg) earns $3.26K/s. Type your own Lava Frog's weight and mutations below.

Lava Frog income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 4 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 4 kg | ×1.00 | $850 | $3.06M |
| 2× | 8 kg | ×1.53 | $1.3K | $4.69M |
| 5× | 20 kg | ×2.70 | $2.29K | $8.26M |
| 10× | 40 kg | ×4.14 | $3.52K | $12.66M |
| 50× | 200 kg | ×11.16 | $9.49K | $34.15M |
| 125× | 500 kg | ×19.64 | $16.69K | $60.09M |
| 250× | 1,000 kg | ×25.91 | $22.03K | $79.29M |
Lava Frog income by mutation
At base weight (4 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 | $850/s | same |
| Silver | $1.02K/s | same |
| Golden | $2.13K/s | same |
| Rainbow | $2.98K/s | same |
| Golden + Bloom | $2.34K/s | $2.66K/s |
| Rainbow + Parasite | $4.67K/s | $8.93K/s |
Worked example: a Golden Lava Frog at twice base weight
- Weight ratio: 8 kg ÷ 4 kg = 2.
- Size multiplier: 237/60 = ×1.5333.
- Golden multiplies by 2.5, so income = $850 × 1.5333 × 2.5 = $3.26K/s, which is $11.73M per hour.
- Saving for the Celebrity Treadmill ($5M) from $0 with only this pet: 25m 34s. A plain Lava Frog at base weight would take 1h 38m.
Common mistakes
- Expecting income to double with weight. A Lava Frog at 8 kg earns $1.3K/s, not double the base. To double its income it has to weigh about 3.08 times the base: 13 kg.
- Forgetting the 125× soft cap. For a Lava Frog that is 500 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 Frog at base weight earns $2.34K/s if mutations add (the wiki calculator's rule) and $2.66K/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.
