Step by step
- 1
Pick what to refine
Choose the resource, the tier and the enchantment. Enchantments start at tier 4; levels that do not exist are greyed out.
- 2
Say how many
Enter how many items you want and the station fee: silver per 100 nutrition, set by the station owner. 500 is common in royal cities.
- 3
Choose the cities
Where you buy the raw resource and the lower tier, where you refine and where you sell. Refining in the resource’s bonus city raises the return rate a lot. “Best cities” tries every combination and picks the most profitable one.
- 4
Set your account
Turn on focus if you spend it, premium if you have it (sales tax 4% instead of 8%) and sell by order if you list instead of selling instantly. Today’s daily bonus is added for you.
- 5
Check the prices
Every price shows its city and how old it is. If it is old, missing or different in game, type yours in. Clear the field to go back to the market price.

Read the result and compare tiers
You earn, you invest, ROI and return rate sit on top, and the breakdown shows every silver. The table at the bottom runs your setup for every tier and enchantment and highlights the best; click a cell to open it.

A worked example
1,000 titanium steel bars (T5) refined in Thetford without focus, sold instantly in Martlock with premium:
- Ore and steel bars
- 1,454,000
- Returned (36.7%)
- −533,600
- Station fee
- 73,800
- Sales (1,000 × 1,450)
- 1,450,000
- Sales tax 4%
- −58,000
- Profit
- +397,800
The station fee is the item’s value × 0.1125 × the fee per 100 nutrition ÷ 100, for every craft. Numbers are an example.
Tips
Questions
Why is a price missing?
Prices on our servers are only kept while they are recent. For items that are rarely traded there may be no recent price in some cities. Type the one you see in game and the calculator uses it.
Should I sell instantly or by order?
Instantly sells to the highest buy order right away. By order lists at the lowest sell order: usually more silver, plus a 2.5% listing fee, and you wait for a buyer.
Is focus worth it?
Turn it on and look at “silver per point” under the breakdown. Compare that number between tiers and resources to spend your focus where it earns most.
What is the daily bonus?
Every day after the reset one crafting or refining group gets +10% and another +20% production bonus. When it matches your resource, the calculator adds it for you; you can also set it by hand.
