Is this Steal a Brainrot game and calculator official?

No. It is a fan-made mini game and static value tool using public wiki data and manual fallback rules where needed.

How is final income calculated?

final income = base income x (mutation multiplier + sum of selected positive trait multipliers)

Why are some exist counts unknown?

Exist count is only shown when a public source page includes a count-like note. Unknown means no reliable count was parsed.

What this tool answers

Exist count

Most public pages do not expose a reliable live count. This site shows parsed count notes only when a source page contains one, and otherwise keeps the field as Unknown.

Mutation value

Mutation multipliers are loaded from the public mutation page and applied directly to base income, so the calculator can answer Gold, Rainbow, Cyber, Divine, and event queries.

Trade check

The W/F/L screen compares projected daily income. It is not a full market price oracle, but it gives a fast first-pass signal before deeper checking.
