🌴 Coral Island — Crop Profit Calculator & Farm Planner
This guide provides the data and methodology behind Coral Island's crop economy. Use the tables below to plan your farm layout, compare artisan processing margins, and build a season-by-season crop rotation that maximizes profit per tile.
📐 Calculation Methodology
Profit per Day (PPD) = (Sell Price × Quality Multiplier − Seed Cost) ÷ Growth Days
For regrowing crops, we calculate across an entire season (28 days):
PPD (Regrow) = [(Sell Price × Quality × Harvests) − Seed Cost] ÷ 28
Harvests = 1 + floor((28 − GrowthDays) ÷ RegrowInterval)

Tip: Grape Wine has the highest multiplier (4.0x) making it the best artisan item in the game. Even though Grape has modest raw PPD, processing turns it into a monster. Plant Grapes in Fall and dedicate at least 10 kegs to them.
