Cost of the next doctrine

Hi all,

Is there a formula (or may be a table) to know the cost in culture of the next doctrine's advance, according to the number of town? The more city we have, the more expensive it is. But how much "more expensive"?

Thanks

Christophe

It depends upon if you have BNW or not and also upon weather or not you adopted a Liberty policy. In addition map size is a factor. But the current value in your game is shown if you hover over the cultural portion of the top bar.

Default in Vanilla and G&K: 15%
Default in BNW: 10%

A liberty policy cuts the cost by a third.

Playing on Large or Huge map size also cuts the cost.

I don't think that it's a set formula. Here's a chart that I was able to find on it:

I am playing with all the extention (I guess it is BNW ?)

Thanks, that help a lot !
So according to the table, each new city add a +30% to the next level. But i guess this might be obsolete since the table is not for BNW (in BNW, the cultural victory is no longuer to get all the doctrine).

I will check in my current game if those number does still apply to BNW.

Most of these things in civ are a set formula but due to truncation or rounding to the nearest 5, it often appears to have no formula.
