Force limit

From EU3 Wiki

The force limit of a country reflects how many regiments they can field without a penalty of increased maintenance. This might also be referred to as the national support limit.

forcelimit = 0.25 * (sum of base tax + additions such as workshops and CoTs) * %modifiers + (HRE bonus)

Modifiers in EU3 & NA are the grand navy and grand army national ideas, Feudal Monarchy govt., and the land/naval policy slider. In In Nomine there are also advisors that modify forcelimits. The Holy Roman Emperor gets an additional bonus of 2x(number of countries in the HRE). Note that %modifiers to tax do not affect force limits and even base tax of colonies is included.

In the In Nomine expansion the naval forcelimit calculation has changed significantly:

naval forcelimit = 0.5 * (sum of base tax + additions such as workshops and CoTs) * %modifiers

Only non-colony (pop 1000+) coastal provinces are counted.

Contribution of provinces of a different culture group (even if accepted) or non-state religion is halved.

Contribution of provinces with no land connection to the capital (even on the same continent) is halved.

Contribution of provinces on a different continent from the capital (even with a land connection) is divided by 20.
