Grow A Garden Value Calculator Formula Explained

Every Grow A Garden value calculator is only as good as the formula behind it. Here is the complete, verified Grow A Garden value calculator formula for 2026 — broken down term by term so you can audit any tool you use (including ours).
The full formula
value = baseValue × (weight / baseWeight)² × mutationMultiplier × (1 + friendBoost) × (1 + eventBoost)
Where mutationMultiplier = 1 + Σ(m − 1) for every active mutation m.
Why weight is squared
The squared weight ratio is the single most overlooked term. A watermelon with 2× the base weight isn't worth 2× — it's worth 4×. A 3× weight fruit is worth 9×. This is why heavy mutations like Chocolate (which boosts weight) compound profit so fast.
Why boosts are multiplicative, not additive
A 50% friend boost and a 100% event boost don't give you +150%. They give you 1.5 × 2.0 = 3.0×. Always run them together when chasing big harvests.
Worked example
Watermelon, baseValue 2,708c, baseWeight 7.3kg. Harvested at 14.6kg with Rainbow + Shocked, 50% friend boost, 100% event boost.
Weight ratio² = (14.6 / 7.3)² = 4. Mutation = 1 + 49 + 99 = 149. Boosts = 1.5 × 2 = 3.
Total = 2,708 × 4 × 149 × 3 = 4,841,904 coins. One fruit.
