What would the other formulas give?
Same inputs, other models seen on third-party sites. Neither reproduces the wiki's printed examples; shown only to explain why numbers differ between sites.
Questions
How do I use the calculator?
Choose a brainrot (or type your own base income, for example 65M), pick its mutation, add the traits it has (add one more than once if it has several), and set how many you own. The result updates as you change anything, and the address bar keeps your setup so you can share the link.
How accurate is it?
The formula is the one in the wiki's template: base income x (mutation + sum of traits), and it reproduces all nine examples printed on the wiki's Mutations page (for example Ventoliero Pavonero with Cyber, Fire and Nyan: 21x, 1.365B/s). Other sites use different formulas and we have not confirmed any of them in game, so check one of your own brainrots against the in-game number.
What does a trait below 1x like Sleepy do?
The wiki says Sleepy and similar display traits should be applied to the total income result, not added in the sum. The calculator multiplies the finished result by 0.5 for Sleepy. This is our reading of one sentence on the wiki and is unverified too.
Does it include Rebirth or friend boosts?
No. We found no primary source for where those enter the income formula, so the calculator covers base income, one mutation, traits and the number of brainrots only.
