Become a Brainrot Income Calculator

Plan your base before spending Cash on Speed or Rarity Upgrade. This calculator estimates total Cash per second from placed Brainrots, average income per slot, optional Mutation multiplier, and Rebirth bonus. Numbers are projections—verify rare units on our Tier List.

How to use the calculator

Use the interactive tool below on this page. Enter how many slots you fill, average Cash/s per Brainrot (from your Tier List targets), Mutation multiplier if applicable (e.g. 2x for event Mutation), and Rebirth multiplier (e.g. 2 after second rebirth). The tool outputs estimated Cash/s and Cash per minute.

Planning scenarios

Scenario A: ten slots at 500 Cash/s with 2x Rebirth = 10,000 Cash/s. Scenario B: same slots at 5,000 Cash/s Mythic average = 100,000 Cash/s—showing why distance steals matter more than calculator tweaks alone. Add offline time mentally: multiply per-minute output by minutes away for AFK estimates.

Limitations

Traits, partial slot counts, and upgrade tiers are not modeled individually—adjust average Cash/s upward if your units are upgraded. Event bonuses apply only during active windows.
