Value by weight & age
See which inputs move a pet's price the most and how the age curve compounds.
Grow a Garden Calculator
Six calculators in one place — pet values, weight conversions, trade verdicts, fruit prices, age growth, and mutation stacks. All client-side and free.
Choose a calculator
Select a mode, fill in the stats from your pet or crop, then calculate.
Select the pet's rarity tier. Base values are community estimates per 1 kg at age 1 with no mutation.
Max age 500. Age 500 ≈ ×3 base value.
Enter the total value of each side. The calculator compares them and returns Win, Fair, or Lose using a ±8% fair window.
Tip: use the Pet Value and Fruit tabs to total each side first.
Bigger size adds up to +50% value.
Mutations stack multiplicatively: total = base × m1 × m2 × m3.
