Income and buy cost are the game's own numbers, as published by steal-a-brainrot.org and cross checked against the Fandom wiki. They are the two figures every honest comparison in this game starts from, which is why the trade checker is built on them. What this page will not give you is a single merged "trade value": the public lists price this brainrot in real money dollars, in-game cash and unlabeled points, and averaging across units would invent a price. The values page explains the problem in full.
Income with mutations
A mutation multiplies income, not the buy cost. If this brainrot spawns with a mutation, its income is the base figure times the multiplier below. The multipliers are documented identically by the Fandom Mutations page and stealarot.com; the figures here are that arithmetic, worked out for this brainrot.
| Mutation | Multiplier | Income |
|---|---|---|
| Gold | x1.25 | $375K/s |
| Diamond | x1.5 | $450K/s |
| Bloodrot | x2 | $600K/s |
| Candy | x4 | $1.2M/s |
| Lava | x6 | $1.8M/s |
| Galaxy | x7 | $2.1M/s |
| YinYang | x7.5 | $2.25M/s |
| Radioactive | x8.5 | $2.55M/s |
| Cursed | x9 | $2.7M/s |
| Divine | x10 | $3M/s |
| Rainbow | x10 | $3M/s |
| Cyber | x11 | $3.3M/s |
| Phantom | x12 | $3.6M/s |
| Crystal | x13 | $3.9M/s |
Traits stack on top: the full formula is base income x (mutation multiplier + trait multipliers). The Fandom page also lists a Celestial mutation at 14x, which no value source prices.
