Calculators
Quick answers from the game's own data, priced on Americas where it helps. Free, no limits.
Resource return rate
Return rate = bonus / (1 + bonus). Cities give 18%, a city's specialty adds more (+40% refining, +15% crafting), focus adds 59%, and the daily bonus adds 10% or 20%.
Repair and quality reroll
Repair = item value x durability lost x 16.5. One reroll costs item value x 4.4 (Normal), 5.5 (Good), 6.6 (Outstanding), 27.5 (Excellent), and quality never drops. A fresh craft lands Normal 68.9%, Good 25%, Outstanding 5%, Excellent 1%, Masterpiece 0.1% before quality bonuses.
Transmutation vs buying
Transmuting takes one of the source resource plus silver, at any refining station. Prices are the cheapest listing in the Royal cities in the last 24 hours. Only raw resources can be transmuted, and stone stops at .3.
Laborer journals
Use the yield your laborer shows in game (100% at base happiness, up to 150% with a good house). Amounts are averages; gathering journals return mostly .0 resources. Crafting laborer mixes follow the wiki.
Server price factor. Repair, reroll and transmutation costs are scaled on each server by Albion's gold-based discount, which isn't published. Leave it at 1, or divide one cost you see in game by the cost shown here and enter the result.
