Income is how much cash a brainrot prints per second — useful for progression. Trade value is what other players will give for it — driven by scarcity. They routinely disagree: Garama and Madundung ($50M/s, ~150,000 copies) trades around 1 Market Point, while Antonio ($125M/s but ~1,506 copies) trades around 150. When in doubt: income is for your base, exist count is for your trades.
Why high income can mean low value
Income is renewable — every player accumulates cash endlessly, so the ability to print more of it commands no scarcity premium. When a high-income brainrot is also abundant (Garama's infamous spawn rate is the canonical example), everyone who wants one has one, and its trade value collapses to almost nothing despite the impressive per-second number. The market prices what cannot be reproduced, and income can always be reproduced.
Why low income can mean high value
Flip it around: a brainrot whose obtain method is gone has a hard supply cap forever. Signore Carapace started life as a $1.3K/s Legendary — genuinely bad — but its brutal craft recipe meant only ~355 were ever made, and today it trades around 850–1,150 Market Points. Even the humble Lirilì Larilà ($3/s) has collector value in certain variants. Discontinued + scarce beats powerful + common, every time.
Using both numbers correctly
Progression decisions (what to place in your base, what to steal for cash flow) should follow income. Trading decisions should follow exist count and market value. The costly mistake is crossing the streams: trading away a scarce low-income unit for an abundant high-income one feels like an upgrade and is almost always a downgrade. Our calculator prices the trade side; the income calculator on the same page handles the cash side.
FAQ
Why is my high-income brainrot worth so little?
Because trade value follows scarcity, not income. If a brainrot is abundant (high exist count), everyone who wants one has one — its income does not create a premium.
What matters more, income or trade value?
For building your base and cash flow: income. For trading: exist count and market value. They answer different questions — never trade based on income alone.
Can a brainrot be valuable with terrible income?
Absolutely. Signore Carapace and Antonio were mediocre earners whose discontinued craft recipes capped supply at a few hundred/thousand copies — they now trade at massive premiums.
