If not explicitly specified, an item's market value defaults to a formula-determined value:
M = (I + W × 0.216) × Q × H
- I = combined market value of all ingredients
- W = work to make the item as displayed in the item information window, assuming 100% work speed; the game gives this value as in-game seconds at normal speed (60 game ticks per second). Note: 1,000 units of work correspond to one in-game day of uninterrupted work.
- Q = quality multiplier (see quality)
- H = health multiplier (only applies if the item has degraded past a certain point)
Items with a market value of above 200 will have their market value rounded to be divisible by 5, with a remainder of 2.5 being rounded down.
