How it works

Income per second = base income × mutation factor

Example: 65M × Gold 1.25 = 81.25M cash per second, or 292.5B per hour at a constant online rate. Example fills the inputs; press Calculate to try it.

Which income should I enter?

Enter the Brainrot's unmodified base income, before mutations, traits or base bonuses. Do not enter an already-modified displayed rate and multiply it again. This tool compares one mutation only; rounded game displays can reduce precision.

Sources and limits

These are dated community reference factors, checked November 5, 2026. The October 14 mutation table, revision 189024 and October 3 factor template, revision 186393 support the listed choices, including Galaxy 7x. The formula reference, revision 161404 defines base income before mutation and trait effects.

Why are Celestial and Eclipse missing?

Celestial and Eclipse have unresolved name and factor references. Older names redirect to Eclipse, while its community references disagree between 14x and 13.5x. The calculator does not assume a fixed coefficient for that case.

Are these factors current in-game measurements?

No. These factors are dated community references, not a current in-game test. Source revision dates record edits, not game changes or observations. Check your actual income if it differs; use the income calculator for a separate trait or collection setup.
