Is the Steal a Brainrot calculator official?

No. BrainrotGrind is an independent fan utility. Estimate calculators expose the assumptions so players can edit them.

Why can I change the growth rate?

Roblox simulator balance changes quickly, so editable formulas are safer than pretending one static table is always correct.
