This thread is to compile the information in this article into a more readable form. I have not tested that the information therein remains accurate.

For each civic category, upkeep is computed as follows, with each individual calculation rounded down and negative numbers replaced with zero. The results are then added.
  • PopulationCost = PopulationModifier * (TotalPopulation - FreePopulation)
  • CityCost = CityModifier * (NumberOfCities - FreeCities)
  • If not organized, BaseCost = PopulationCost + CityCost
  • If organized, BaseCost = (PopulationCost + CityCost) / 2
  • CivicUpkeep = BaseCost * DifficultyModifier

Category|FreePopulation|FreeCities
Government|8|3
Legal|9|2
Labor|10|1
Economy|11|0
Regligion|12|-1

Upkeep|PopulationModifier|CityModifier
No|0|0
Low|0.08|0.4
Medium|0.12|0.5
High|0.16|0.6

Difficulty|Player DifficultyModifier|AI DifficultyModifier
Settler|0.5|1
Chieftan|0.6|1
Warlord|0.7|1
