How the game calculates claim costs?

[RafaMonteiro]

So, I just form Ireland and fabricated a claim in 1 county of wales and it costs 110 gold ??
I notice that it is growing in cost quite fast, is it based on how much money I make per year??
Im barely hitting the 900s how the game will be towards the end? Or when im about to form UK.. 1000 gold per county?

Not sure if it's realm size, or income.

Either way, fabricating claims is only useful for your 1st title or two.
Once you become a King, it's far more efficient (both in terms of cost & time) to invite claimants, land them, and push their claims.
