经济

领地年收入结算在头衔界面显示（F1）

CK2中的经济系统反映了中世纪欧洲的 封建制度。游戏拥有一个等级体系，其中的大部分贵族为一位领主效力。

定期收入

游牧制有特殊规则，见下文。

直辖领税收

主条目：直辖领收入

直辖领的个人地产通常是低等级封建统治者的基本收入来源，和贵人的重要收入来源。管理能力显著影响直辖领收入：

• 个人和配偶的管理影响你的直辖领上限。
• 你的财政总管 的能力增加你指派他征收赋税的任务省份的收入。
• 国家管理属性对所有直辖领收入提供增益。

某些建筑也增加你的地产的税收，它们是城堡墙垣和市镇这些你在游戏早期应该先投资的建筑。

领主税

主条目：领主税

你的封臣向你缴税，基于你的税率和他们的收入，以及他们对你的好感——负好感意味着比通常更少的税。（特殊规则用于天主教神权政体，见下文。）税率是你的直辖领法律的一部分，并且每个政体类型分开指定；拥有 御前会议时，高税率减少领主征召兵上限量，否则除了减少对你的好感没有其他的负面效果。

• 无论税率多少，封建封臣向你提供收入通常都很少，他们更擅长向你提供征召兵。
• 共和政体的封臣，相反地，军事力量薄弱但长于赚钱，正是因为这个原因，封建统治者被限制为<10%的省份能被共和政体控制。商业共和国也仅能缴纳共和政体税率的一半，即使庞大，提供的税收也不比一个富裕城市高多少。
• 神权政体相对富裕且强大。但如果是天主教，仅有比起[[|Pope|教宗]]更喜欢你时，他们将向你缴税，此种情况很少发生。而且，一位附庸教宗或对立教宗仅在对你有正面好感时向你缴税。

封臣缴纳的税收可在领主的“封臣”列表中看见，每个封建政体类型的总税收在领主的直辖领界面中显示。

贸易

主条目：贸易站

主条目：丝绸之路

沿海或位于重要的丝绸之路省份可以以非常低的建造花费来产生大量的贸易收入。The tax income from cities and the trade income from all trade posts within the associated trade zone is also boosted depending on its size, up to a limit of ~40% for cities and ~80% for trade posts in a ~five-trade-post zone; in Silk Road counties, the city income boost also applies to castles and temples.

然而，只有重要的丝绸之路省份的控制者能够在那里建造一座贸易站，如果此省份易手，贸易站将被破坏；并且丝绸之路外的贸易站仅能被商业共和国的贵人建造，对他们来说这是收入的基本来源。

非商业共和国统治者也可使用共和国来提升沿海城市的收入——要么利用一个已经存在的毗邻你的共和国，或者，如果你控制一个（最好是小）沿海公国，创建一个你自己的附属商业共和国。

对于游牧统治者

游牧统治者完全不能收取领主税，并且他们收取单一的游牧税而不是直辖领税收，基于他们的 和未占用 ，位于游牧制首都的建筑以及国家管理属性。他们照例从丝绸之路贸易中获利，并且如果他们的游牧制首都位于一个重要的丝绸之路省份，他们可以在那里建造一个铸币匠从而提高持有的全部贸易站的价值。

战争

Winning certain types of wars can increase your wealth:

• Expanding your realm will increase your potential tax base. Unlike levies, tax income is not affected by any de jure modifiers.
• Winning an Embargo war pays money for every trade post on your lands. However, if the trade posts form a big trade zone, your cities within the trade zone might suffer a substantial loss of income; consider only fighting an Embargo war when another merchant republic pays you to do so, the assumption being that the other merchant republic will then build trade posts to replace those razed.
• Winning a Free Captives war extracts funds.
• Winning an Extort Tribute war forces the defender to pay 40% of their income until your death. Other types of tributaries provide less income but persist through succession.
• Winning a defensive war usually results in payments of reparations. The defender's computed income may be largest if you avoid occupying their demesne.

Simply fighting a war can increase your wealth as well:

• Sieges result in a small amount of gold, and captured nobles will ransom themselves.
• As a Catholic, fighting wars against heathens might earn you some funding from the Papacy as well. However, because you're employing the levies in the first place, this is not always cost-effective (unless you exclusively use levies from your vassals, which presents its own set of problems).

But money can also be lost through conflict:

• If provinces are sieged or raided, you and your vassals lose tax income, and recovery can take a long time.
• With The Reaper's Due DLC, prolonged sieges/occupation also decrease prosperity.

劫掠

Pagan, Norse-cultured, or nomadic rulers, and all independent and some vassal tribal rulers, can raid neighbouring counties for gold and prestige, or any coastal county if they have ships. Raiding armies cost only 10% of regular maintenance when otherwise at peace, and need not be large enough to siege holdings (known as sacking in this case), but successful sieges by raiders (at most once every three years) do give you much more gold.

For tribal rulers, raids on rich, but poorly defended and fortified counties are the best way to quickly make money, and a good way to raise much-needed prestige. However, beware of your target's armies - if they engage your raiders and win, you won't get any gold, and won't be able to raid the target realm again for five years. Even after your raid has concluded, the target realm's armies will remain hostile to you for half a year.

Tribal and nomadic rulers can also pillage holdings they control, slowly destroying them (two building levels every six months, or once every ten years for occupied enemy holdings) until no buildings are left, at which point the holding slot becomes empty. This has the following benefits:

• 50 gold (some population instead for nomads pillaging tribes) and five technology points per holding and pillaging tick)
• Tribal rulers: Increased income and levies per empty holding slot if there is a tribe holding in the same county
• Nomad rulers: Increased maximum population per empty holding slot, for more potential nomad tax and horde troops
• The land becomes effectively useless for feudal rulers, who will likely make little to no effort to claim it for themselves

Pillaging also raises revolt risk by a massive 30%, so you should keep some armies near counties where pillaging is in progress. The revolt risk does not stack when pillaging multiple holdings in the same county, though.

囚犯

Imprison without tyranny:

• Battles
• Sieges
• Imprison plotters rather than politely asking them to stop.
  • Imprisoning the vassal of a vassal is nearly risk-free. If the imprisonment fails, they will abdicate to their heir and flee.
• Imprison excommunicated characters
• With the Intrigue focus, spy on characters to uncover imprisonment reasons, or simply kidnap them

Turn prisoners into cash:

• Banish prisoners who are also your courtiers, seizing all their cash.
  • If they're not your courtier, try inviting their spouse to your court before banishing them.
• Ransom prisoners who have money or are closely related to landowners.

继承判定

• 对于没有继承人的直属封臣死亡的情况判定：
  • 如果直属封臣去世而膝下无有效继承人，则领主头衔回到玩家手中。由玩家您继承头衔，金钱，宝具，近卫军和科研点数。
• 对于富有的廷臣在你的宫廷里死亡而没有继承人的情况下：
  • 如果廷臣“没有父母”和“没有活着的后代”在你的宫廷里死亡，玩家就会继承他们的金钱。
  • 出身卑贱的宫廷成员往往很富有。 例如前市长/主教或是因圣战失败或被[剥夺头衔]而流离失所的这类人。

宗教决议

These decisions require Sons of Abraham.

• Borrow from holy orders.
• Borrow 300 gold from Jewish moneylenders.
  • Expel Jews (if you are independent), cancelling the debt and giving even more gold (based on your yearly income). Be warned that this action will give your ruler the Arbitrary trait.
    • After 20 years or a succession, welcome the Jews back (if you are king).
• Ask the Pope for money
  • A Pope or Antipope with many virtues will collect taxes from more bishops

花费财富

Money can be spent in many ways, including:

• Construction
  • Some new buildings generate income and pay for themselves over time
    • Patricians of merchant republics can build trade posts to increase their income, as can anyone along the Silk Road
  • Construction of new holdings and hospital buildings requires significant wealth
• War
  • Supporting demesne levies costs money while they are raised
  • Hiring mercenaries and reinforcing retinues costs even more
• Relations
  • Bribes to increase opinion from other characters
  • Favors to make specific requests from other characters
• Creating or peacefully usurping titles

As one can imagine, spending your wealth with the aim of further increasing it is a key part of gameplay.

债务

如果你的金钱为负数：

• 战争将变得十分困难：
  • 你不能在破产时宣战。
  • 你的军队士气将会下降。
  • 雇佣兵可能会逃跑，叛变，或者是决定入侵你的国土。
• 负面修正将会出现在你的直辖省份，形成长期的负面效果。
  • 强盗 (即 无能的统治者)增加叛乱风险
  • 盗贼工会降低直辖领收入
  • 拦路强盗减少征召兵规模和补给上限
  • 走私链减慢建筑时间并增加建筑花费，同时增加疾病风险
• 可能出现事件允许你借钱或者向封臣要钱

幸运的是，你的继承人不会继承你的债务。但是，继承人会继承直辖省份的负面修正。

总结

Through several different methods, you can increase your income, but if you're not careful, you won't get any (or much) use out of it.

• Construct buildings.
• Without Conclave: find a suitable tax level. Balance it between good opinion and high taxes. Remember that you need good opinion for high vassal levies.
• If you get the opportunity (as a Catholic ruler), appoint an antipope.
• Research relevant technology.
• Create vassal republics.
• Take control of the Silk Road for your Demense.
