Provincial base production in 1444.

Production is, together with taxation and trade, one of the three primary sources of income in Europa Universalis IV. It represents the amount of income generated by local trade good producers and is, unlike in EU3, added directly to the country's monthly income. In contrast to trade income, it is not subject to the competition with other nations via merchants or light ships, but based in your provinces. Like taxation, it is therefore a natural source of income for large sprawling empires, in particular those who lack the strategic location and/or ideas (naval, diplomatic) to effectively compete in the open trade market (such as land-locked nations). Larger nations will benefit greatly from having at least one production increasing modifier.

Production income[edit | edit source]

A nation's production income is the sum of the production income of all its provinces. Territorial provinces will usually generate less production income due to the higher local autonomy floor. The values shown in the provincial economic detail box are monthly values (yearly values are shown in the extended tool-tip). Production income can be further broken down into the below 3 key factors.

See also: Development

Goods produced represents the amount of goods the province can produce and is greatly affected by occupying hostile forces and war-exhaustion.

The value can be increased by constructing manufactories or by development of the province's base production value (an increase of Local goods produced +0.20 local goods produced per production point).

Trade value.png Trade value[edit | edit source]

Main article: Trade goods#Trade value

Trade value represents the total value of the goods transferred to local trade node from the province. It is largely determined by the local goods, amount of local goods produced and triggered event price modifiers.

Production efficiency.png Production efficiency[edit | edit source]

Production efficiency is a key factor to describe how efficiently a given province or a whole country can produce goods. The global production efficiency slowly increases over the course of the game with the increase of Administrative technology.png Administrative technology modeling the arrival of new and more efficient production methods over the course of centuries. In addition, the player may encounter various events, decisions, triggered modifiers, and mission rewards during their campaign that may affect either local or global production efficiency.

Note: The base value is not mentioned in the expanded province tooltip and has to be added to the value mentioned (i.e., 80% production efficiency is calculated as 180%).

Production efficiency has a base value of 100% and is further modified by the following:

Production calculation[edit | edit source]


Formula[edit | edit source]

Production.png Production income is formulated as follows:

The sum of the country-wide production efficiency modifiers has a minimum value of 1%. The local production efficiency modifiers can be negative, but the total production income can't fall below 0.

Trade value.png Trade value and Goods produced.png Goods produced can be further broken down as:

Flat and relative trade value modifiers are relatively rare and only exist as local and not as country wide modifiers.

Example[edit | edit source]

Consider the province Ghent with its Cloth.png Cloth trade good (with New Draperies price modifier), owned by Flag of Flanders Flanders. The nation has constructed a manufactory and a production building as well as invested in Administrative technology.png Administrative technology and Economic idea group.png Economic idea group increasing its Production efficiency.png production efficiency. The province has some Local autonomy.png local autonomy and War exhaustion.png war exhaustion.

Note: The displayed values only show 2 digits after the decimal, but include 3 digits after the decimal when performing any calculations.

Production strategy[edit | edit source]

Buildings[edit | edit source]

See also: Buildings

Two buildings increase Production efficiency.png production efficiency (one replaces the other); another provides a bonus to Goods produced.png goods produced, thus essentially increasing both production and trade income.

Prioritize constructing production buildings in the order prescribed below:

  • Provinces with high value trade goods, i.e.: Silk.png Silk, Dyes.png Dyes, Ivory.png Ivory, Iron.png Iron,Cocoa.png Cocoa etc.
  • Provinces with very high base production value.
  • Territorial provinces (and trade companies) which are beneficial to player's trade with high value trade goods / high base production value.
  • Provinces with trade goods which the nation is trying to become a production leader or trading leader (for the given bonus).

Notes: Gold Gold provinces do not benefit from production efficiency and can deplete at any level of production above 1 (the chance is much smaller at lower levels of production). Also, consider that some trade good provinces may be worthy of investments in manufactories and production buildings in the early game due to their timed peak value.

Development[edit | edit source]

With the current version of EU4, it is now possible to develop in the base game. Increasing production development requires expenditure in Diplomatic power.png Diplomatic power. Investing some production points can yield high monetary return taking all of aforementioned into account and as it scale very well with other modifiers, it is then recommended to not develop your land with Administrative power.pngAdmin power as it will upgrade the developement cost of the province. Military power.png Military power is also very good to dev with.
