Fruit Tree Farming and Processing Calculator (Stardew Valley 1.6.15)

Fruit Tree processing calculator

This calculator uses Stardew Valley 1.6.15.24356 item catalog, machine rules, and shop catalog records. It compares one machine batch and never converts barter items into an invented gold cost.

Local processing rules

Raw fruit: base price × input quality multiplier.
Jelly: one fruit → 2 × base price + 50g; 4,000 machine minutes (about 2.5 days). The jar does not copy input quality.
Wine: one fruit → 3 × base price; 10,000 machine minutes (about 6.25 days). The keg does not copy input quality.
Dried Fruit: five fruit → one output worth floor(5 × base price × 1.5) + 25g; ready after one day.
The local CreateFlavoredDriedFruit logic copies the input stack’s quality to the Dried Fruit. This is a current 1.6.15 evidence correction: input quality is ignored by wine and jelly but not by Dried Fruit.
Artisan is applied to the processed good only. It never changes the raw fruit’s price.

Island Trader sapling trades

Sapling	Local trade	Gold ROI handling
Banana Sapling	5 Dragon Teeth	Do not treat it as 75 Mussels or assign an arbitrary gold cost.
Mango Sapling	75 Mussels	Keep the barter cost separate unless the user supplies an opportunity value.

Fruit tree planning notes

A mature fruit tree produces one fruit per day in its outdoor fruiting season; up to three uncollected fruit can remain on the tree.
Greenhouse and Ginger Island fruit trees can produce year-round once mature.
Older trees improve fruit quality over time. That improves raw sale value and the local Dried Fruit quality copied from a same-quality five-fruit stack, but it does not raise the base formula for wine or jelly.
Machine capacity matters: a higher per-item price is not automatically the best use of limited kegs or jars.
