Frog Income Calculator

For the Roblox game Steal An Egg. Type your Frog'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 Frog earns $3 per second at its base weight of 3 kg with no mutations. That is $10.8K per hour. Every doubling of its weight multiplies income by about 1.53, so a Golden Frog at twice the base weight (6 kg) earns $11.5/s. Type your own Frog's weight and mutations below.

Frog income by weight

No mutations, no boosts. The size multiplier is (weight ÷ 3 kg)37/60 up to 125× base weight, then grows more slowly.

1×3 kg×1.00$3$10.8K

Frog income by mutation

At base weight (3 kg). With two mutations the wiki disagrees with itself on whether they add or multiply, so both are shown.

MutationIf they addIf they multiply
None$3/ssame
Silver$3.6/ssame
Golden$7.5/ssame
Rainbow$10.5/ssame
Golden + Bloom$8.25/s$9.38/s
Rainbow + Parasite$16.5/s$31.5/s

Worked example: a Golden Frog at twice base weight

  1. Weight ratio: 6 kg ÷ 3 kg = 2.
  2. Size multiplier: 237/60 = ×1.5333.
  3. Golden multiplies by 2.5, so income = $3 × 1.5333 × 2.5 = $11.5/s, which is $41.4K per hour.
  4. Saving for the Sci-Fi Treadmill ($15K) from $0 with only this pet: 21m 44s. A plain Frog at base weight would take 1h 23m.
