Castle vs city vs temple

Crusader Kings III castles, cities and temples level by level: tax and levies at development 30, garrison and fort, what each upgrade pays back, and what you actually receive when a baron, mayor or bishop holds it.

Castles, cities and temples at their top level in Crusader Kings III 1.20.1.2 are Castle (1.5 gold a month and 719 levies at level 4, development 30), City (2.99 gold a month and 259 levies at level 4, development 30) and Temple (2.3 gold a month and 230 levies at level 4, development 30); the holding's own tax and levies with the development bonus; a vassal sends 20% of a city's tax (republic) or 10% of a castle's (feudal, normal). Patch 1.20.1.2, from game/common/holdings/00_holdings.txt.

Castle, city or temple at level 4

A city taxes 2× what a castle does (2.99 against 1.5 gold a month at development 30); a castle raises 2.78× the city's levies and adds fort level +13. Held by a mayor, a city sends you 0.6 gold a month — a 20% share.

What you get from it, by who holds it

Level 4, development 30: the share of its tax and levies that reaches you (the game's subject contracts) and what that comes to.

Computed ranking

Tax = the holding level's Tax (monthly_income) × (1 + 0.5 × development ÷ 100); levies = its levies × (1 + 0.5 × development ÷ 100) (NDomain TAX_AT_MAX_COUNTY_DEVELOPMENT, LEVIES_AT_MAX_COUNTY_DEVELOPMENT). A vassal's holding sends its liege a share: feudal vassal at normal obligations 10% of tax and 25% of levies, republic vassal 20% and 10%, theocratic vassal of the liege's faith 5% + 10% of tax per piety level of the liege (none at level 0) and 10% of levies per level. Upgrade payback = the level's gold ÷ (tax it adds × 12).
