Rune Factory: Guardians of Azuma is opaque when it comes to how much gold each shop is producing and what impacts that amount. This guide is intended to show how shops income is calculated so that players can maximize profitability.

Excluding the Blacksmith and Carpenter shops, all other shops use the following formula for determining how much gold they generate per day.

The factors in the formula:

• Base Gold: Each shop has a fixed amount of gold they will generate. The Village Trade Bonus does not apply to this.
  
• Villager Bonus: The amount of gold per villager that is added to the income. This gets multiplied by the number of villagers present in the village.
  
• Village Trading Bonus: The trading bonus that the village has for its stats. The bonus is applied to the Villager Bonus. So a 10% Villager Trading Bonus will increase the Villager Bonus by 10%. After this value is applied any decimal is truncated off.
  
• Villager Trading Bonus: The total trading percentage bonuses the villager running the shop has from all their qualities. So a Hard Working Cheerful villager will get a 25% bonus. This bonus is applied last to the combined total of everything else. After it is applied any decimal is truncated.

You will notice that the villager productivity (represented in hoes) is not in the list. So a 3 hoe villager that is Cheerful will outperform a 5 hoe villager that is Hard Working.

This is how the factors look as a formula:
TRUNC(TRUNC(baseGold + (villagerBonus*numberOfVillagers) * (1+villageTradingBonus)) * (1 + villagerTradingBonus))

One last note: I noticed some odd truncating where it would sometimes round down whole numbers resulting in numbers like 200.0 in the Business Income showing as 199.

* As of 1.0.4 Permafrost Izakaya ignores the Village Trade Bonus and instead uses a fixed 8.4%. This could change in a future patch if this was not intended.

Using the above table, for a Chemist that is run by a Cheerful villager in a village of 20 people with a 5% trading bonus:

First step is the Villager Bonus * Number of Villagers * Village Trading Bonus:
13 * 20 * 1.05 = 273 gold

Next add the base gold to it:
273 + 500 = 773 gold

Then lastly multiply that by 1.2 since the chemist's Cheerful quality gives a 20% trading bonus:
773 * 1.2 = 927.6

Truncate that result and you get 927 gold.

As mentioned earlier Blacksmith and Carpenter shops do not use the above formula. Instead they always produce 400 coin just by being placed even when unstaffed, and when staffed they provided a fixed bonus based on the level of the village. The number of villagers present, villager trade bonuses, village trade bonuses, nor any other factor influences how much gold they produce.


So a blacksmith set up in a level 10 village with a blacksmith assigned will produce 1,400 gold per day. Thank you akvail and Mist of Majora for help with getting some numbers I was missing.

Blacksmiths dominate. Their shops are slightly smaller than Carpenters and yield the same income, so if you have a villager that is both a blacksmith and a carpenter it is better to build them a blacksmith. Also, other qualities and productivity of the villager do not matter. So a 3 hoe Blacksmith in a level 10 village will out produce any other shop.

The Chemist comes in after Blacksmith and Carpenter. Even with a 30 person village with a 12.5% village trading bonus and has Life of the Party for an additional 30% bonus on top of that will come in at 1,219 gold. Still very impressive, but less than the 1,400 of a blacksmith or carpenter.

Below Chemist is the Izakaya which has the best profit for villagers without a trade skill. All other stalls and shops are only worth building if you have need of them. For example the Flower Cart if you are trying to buy lots of flower seeds.

Lastly as mentioned earlier focus on villager qualities not productivity for those you want to run shops. Cheerful + Hard Worker will net a 25% bonus which is nice if you are having trouble finding villagers with Life of the Party (which is a 30% bonus).
