Mutation Multiplier Math, Solved
Getting a mutation is exciting, but doing the math to figure out what your plant is actually worth? Not so much. Our mutation calculator supports over 150 unique game mutations.
- Base multipliers for rare finds like Gold, Rainbow, or Radioactive
- Weather-based events like Acid Rain or Heat Wave
- Complex stacking rules for hybrid mutations
Just click the mutations you rolled, and the calculator updates the final value instantly. Always check your mutated crops here before selling them to an NPC or trading them to another player.
