The average production cost (APC) is the average of all the production costs per marketplace transaction in the last 7 days.

Example:

To find out the Average Production Cost, APC, you need to add the Price/Units column and divide it by the number of types of goods sold on the market (in this example 8).

During a period of 7 days the following items were sold in the market.

Item Sold in Last 7 Days Price Units* Price/Units
Q1 Food 0.42 BRL 1 0.42 BRL
Q5 Food 3.40 BRL 1 3.40 BRL
Q4 House 351.00 BRL 200 1.76 BRL
Q2 Gift 1.00 BRL 2 0.50 BRL
Q1 Moving 10.00 BRL 10 1.00 BRL
Q5 Weapons 70.00 BRL 5 14.00 BRL
Q4 House 360.00 BRL 200 1.80 BRL
Q5 Defense System 4500.00 BRL 2000 2.25 BRL

* See Productivity Points (PP)

Add up the price per units : 0.42 + 3.40 + 1.76 + 0.50 + 1.00 + 14.00 + 1.80 + 2.25 = 25.13
Divide the total by number of types of goods on the market= 25.13/8 = 3.14125

So the APC for the example above is 3.14 BRL.
