Fox Income Calculator
For the Roblox game Steal An Egg. Type your Fox'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 Fox earns $180 per second at its base weight of 28 kg with no mutations. That is $648K per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Fox at twice the base weight (56 kg) earns $690/s. Type your own Fox's weight and mutations below.

Fox income by weight
No mutations, no boosts. The size multiplier is (weight ÷ 28 kg)37/60 up to 125× base weight, then grows more slowly.
| × base | Weight | Size | Per second | Per hour |
|---|---|---|---|---|
| 1× | 28 kg | ×1.00 | $180 | $648K |
| 2× | 56 kg | ×1.53 | $276 | $993.6K |
| 5× | 140 kg | ×2.70 | $485.63 | $1.75M |
| 10× | 280 kg | ×4.14 | $744.63 | $2.68M |
| 50× | 1,400 kg | ×11.16 | $2.01K | $7.23M |
| 125× | 3,500 kg | ×19.64 | $3.53K | $12.73M |
| 250× | 7,000 kg | ×25.91 | $4.66K | $16.79M |
Fox income by mutation
At base weight (28 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 Fox at twice base weight
- Weight ratio: 56 kg ÷ 28 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 Fox at base weight would take 23m 08s.
Common mistakes
- Expecting income to double with weight. A Fox at 56 kg earns $276/s, not double the base. To double its income it has to weigh about 3.08 times the base: 87 kg.
- Forgetting the 125× soft cap. For a Fox that is 3,500 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 Fox 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.
