Farming profit per plot and per island

The Farming page covers crops, herbs and animals. This guide follows the seed calculation; animals use the same idea with their own product, offspring and food.

Yield of one seed

• A planted seed yields 9 crops on average with Premium (the midpoint of 6 to 12), half without Premium.
• Farming on an island whose city has the bonus for that crop adds 10%.
• Each harvest has a 10% chance of an earthworm, two with Premium.

Seed return and focus

Each seed has a chance to come back. Watering with focus adds the tier's farm bonus to that chance. The app assumes you replant what comes back:

• below 100%, you only buy the missing share (60% back means 40% of a seed bought);
• at 100% or more, the seed is free and the surplus is sold.

Seeds bought with a buy order add the 2.5% setup fee.

Profit per seed

Crops, surplus seeds and earthworms are sold, and lose the market sales cut (4% with Premium, 8% without). Replanted seeds never go to market, so they are not taxed.

profit per seed = sales after tax − seed cost

Profit % divides it by the silver actually committed (the seeds you buy plus the tax), and Profit / focus by the focus spent watering.

Plots, islands and time

A plot holds 9 seeds and an island 16 plots. Set how many plots you farm on each row: the Result tab adds them up. The weekly and monthly figures assume you replant once a day: the grow time is rounded to whole days (at least one) to count the cycles.

Prices

Seed and product prices come from the market like everywhere else. In the settings you can also price every seed at the game merchant's price, and choose the averaging window of the Avg price type.
