Answered Culture Bonus calculation ???

[DeletedUser3314]

Someone om my live world asked how the culture bonus is calculated. So what determines the values needed to get 100/125/150/160/170% bonus ?

For example, 3 chapter 3 accounts, current culture values needed to get a bonus are:

	A (working pop.: 2296)	B (working pop.: 2176)	C (working pop.: 2731)
100%
125%	880	870	980
150%	1800	1700	2000
160%	2700	2600
170%	3600	3500

A&B are almost identical, same number (and level) of residences, workshops, T1 & T2, MH, barrack, armory and culture buildings. Only B still has some T1 factories to upgrade. C has a lot more residences. After upgrading 1 factory for B the culture bonus values became the same as A. So it has probably something to do with your working population (and most likely chapter as well).

I had a look here and on other sites but couldn't find anything on the subject. Does someone know how this is calculated ?

Bonus is calculated as
working pop+required culture = goal
if available culture is 20% of goal you get 125% boost
40%=150% boost
60%=160% boost
80%=170% boost
It's rounded to 2 significant digits, so if you need 23,450 it rounds to 23,000 needed

thats how @SoggyShorts explained few years ago
