Traits and mutations
15 mutations and 105 traits with their multipliers, and the three formulas side by side
The formula we use
income = base income × (mutation + sum of traits)
Default counts as 1x. Gold 1.25x, Diamond 1.5x and Eclipse 14x are mutations; Fire and Nyan 5x are traits. All 16 mutation values and 105 trait values are on the traits page. Sleepy (0.5x) is the one trait below 1x; the wiki says such traits apply to the finished result, so the calculator multiplies the result by it.
Questions
How is income calculated in Steal a Brainrot?
The wiki's formula template says: base income x (mutation multiplier + the sum of all trait multipliers). Example from the wiki: 65M/s base, Cyber (11x), Fire (5x) and Nyan (5x) give a 21x multiplier and 1.365B/s. We have not checked this in game.
Why do other sites give different numbers?
Sources disagree. The wiki's written line on its Mutations page reads like (base x mutation) + traits, but its own examples add the multipliers first. One third-party site uses base x (1 + sum of bonuses) and others multiply everything. For the same 65M/s brainrot with Cyber, Fire and Nyan that gives 1.365B/s (wiki examples), 1.235B/s or 17.875B/s. We follow the wiki examples and say so on every calculator page.
Can a brainrot have more than one mutation or trait?
Per the wiki, only one mutation can be on a brainrot, while traits can appear several times. The calculator lets you add a trait more than once.
