How It Works
1Base income × Mutation multiplier × Trait multiplier = final $/s
2Break-even = brainrot cost ÷ (final $/s × 60 × 60 × 24)
3Limited mutations (Cyber, Disco, Divine) decay never — permanent value
4Diamond/Gold are permanent floors; Cyber/Disco/Divine are limited ceilings
What's New
Pick any brainrot — the calculator pulls live base income from our DB
Stack any mutation × any trait — math respects multiplier order
See break-even time vs cost in seconds, minutes, hours
Compare two builds side-by-side: which one pays back faster?
Lock-in projection: estimate income after 30/60/90 day rebirth cycles

Key Takeaways
- Traits multiply your Brainrot's base income per second
- Mutation drops are rarer but give bigger multipliers
- Higher-rarity Brainrots have better trait roll odds
- Re-rolling is worth it for Legendary+ Brainrots
