The Crafting Calculator is used to calculate the costs and profits to be had by crafting a particular item. Additionally, you can save the market values of the items used by a given recipe to be shared with others. The community is encouraged to share known and accurate market value information for the benefit of all.

To use this tool:

1. Select an item type that you wish to craft. The calculator will retrieve the associated recipe as well as any market values that have been shared in the past 48 hours.
2. Select the location where you will be doing your crafting, this impacts the resource return rate.
3. Enter the usage fee associated with the crafting station you will be using.
4. Validate any shared market values for reasonableness. Market value is intended to reflect the current generally available market price that the given item is selling for on the Caerleon public market. Update any shared market values as necessary.
5. Select "Calculate Profitability". The calculator will calculate your total costs and profitability for the item being crafted using the provided crafting station details and market values.
