How Grow a Garden values are calculated

A transparent walkthrough of every input used by this site, why variants and mutations are separate, and how to check a result yourself.

round(basePrice × (weight ÷ baseWeight)² × variantMultiplier × (1 + Σ mutationBonus) × quantity × (1 + friendBoost ÷ 100))

The six calculation steps

Choose the cropLoad its community-listed base price and base weight.
Calculate the weight ratioDivide the actual weight by the crop's base weight, then square that ratio.
Apply one growth variantUse Normal ×1, Silver ×5, Gold ×20, or Rainbow ×50.
Combine environmental mutationsStart at 1 and add each mutation's stored bonus. Do not multiply environmental mutations together.
Apply quantity and friend boostMultiply by the whole-crop quantity and by 1 plus the friend-boost percentage.
Round the estimateThe displayed result is rounded to the nearest whole Sheckle.

Worked example: Rainbow Carrot with Shocked

A Carrot has a base price of 20 and base weight of 0.2697 kg. At base weight its squared ratio is 1. Rainbow contributes ×50. Shocked contributes +99 to the environmental layer, so that layer equals 100.

20 × 1² × 50 × (1 + 99) = 100,000 Sheckles

Reverse calculation

The calculator can solve for the required weight by dividing the target value by every non-weight factor, taking the square root, and multiplying by the crop's base weight.
