Trade goods
- This article deals with trade goods and their production and value before they enter the trade network or produce production income. For information about the trade network and income, see trade.
Each province produces one type of trade goods; the goods produced is the largest determinant of the province's trade value. In turn, trade value determines the province's production income and flows into the trade network.

The goods produced of a province is calculated as follows:
Various events, decisions and missions also impact goods produced in addition to the local and national goods produced values and modifiers which are mentioned in the tables below.

National goods produced modifiers from ideas and policies[edit | edit source]
Trade value[edit | edit source]

A province's trade value is the price of the trade good times the amount of goods produced in the province:
Trade value then flows into the calculations for a province's production value (in ducats) and the overall trade value of a node. Note that all values listed in the province window for trade value are shown as yearly values. The production and tax value calculations in the upper part of the province screen (which determine the
ducats each provinces contributes directly to the treasury) are shown as monthly values.
Gold is treated as a special case and does not have any trade value (see full treatment below). However, it does contribute to a province's production value.
Trade[edit | edit source]
- Main article: Trade
The trade value produced in a province flows into the province's trade node. Eventually it will be collected and turned into trade income.
Production[edit | edit source]
- Main article: Production
Local trade value also produces production income for the owner of the province directly; this income is modified by production efficiency.

Prices[edit | edit source]
- Main article: Price Change events
Each trade good has a universal base value[1] (for 1 unit). This base price is subject to change through special price change events. While most of these events are not tied to a specific year, they tend to fire usually around the same timeframe in most of the campaigns. It is possible to view the price modifiers affecting a trade good by hovering over it.
The base price and the different price modifiers are summarized in the table below.
Bonuses[edit | edit source]
- Trading in bonus - Controlling at least 20% of the global trade in a trade good will give the country a modifier "Trading in (trade good)", which gives a national bonus. (The bonus is conferred when market share reaches 20% but a country will not immediately lose the bonus when its market share drops below 20%. The country will retain the bonus as long as it maintains above 15% market share.) The market share can be found in the ledger under "Strategic Goods". Control is computed using the trade power share in each node times the amount of the good produced locally in that node.
- Production leader bonus - Producing the most of a particular trade good will make a country the "production leader" of that trade good, and will provide a bonus to the production of goods of this type:[2]
- Per-province bonus - A province-level bonus applied to the province based on the trade goods being produced there (requires
Rights of Man).
Events[edit | edit source]
- Main article: Trade goods events
Various trade goods trigger certain events when the player country owns at least one province which produces this trade good.
List[edit | edit source]
Notes:
- The years noted next to the price modifier events are there for convenience only (earliest possible approximations based on technology, institutions and ages). The events are more likely to appear at later dates during a normal playthrough.
- Since
gold is handled differently from the other trade goods, it is explained in a dedicated section further below.

Gold mines[edit | edit source]
Gold is a special "trade" good that has both advantages and disadvantages: it will give a direct boost to the economy, but also increase inflation every month. If a nation owns many gold mines, it is possible that the inflation incurred negates the increase in income received. Gold does not produce any trade value; it is instead converted directly into ducats at the rate of 40
per year per unit of goods produced. This translates to 8
per base production per year.
Income from gold does not benefit from production efficiency, and there is no manufactory for gold. Also being the production leader or trading in gold gives no bonuses.
Primitive nations convert gold to cash at a rate of only 1:4, 10 times less than non-primitives. They accordingly receive a smaller amount of inflation.
A country will suffer 0.5 inflation per year times the proportion of income from gold. For example, a country which generates 10% of their income from gold would get 0.05% inflation per year. Practically speaking, each 5.33% share of income from gold will require 1 administrative power per year to cancel out inflation if it is not removed through other means. To cancel yearly inflation from gold provinces without spending
administrative power to reduce inflation manually, a country needs to have
yearly inflation reduction modifiers. The amount of yearly inflation reduction needed is shown in the table below. The right column shows what percentage of total income can come from gold without gaining inflation.
Yearly ![]() |
Proportion of income from gold that will not increase yearly inflation |
---|---|
–0.05 | ≤10% |
–0.10 | ≤20% |
–0.20 | ≤40% |
–0.30 | ≤60% |
–0.40 | ≤80% |
–0.50 | ≤100% |
Gold income is affected by local autonomy, with a percent of the total possible income gained equal to the local autonomy being deducted.
Gold mine depletion[edit | edit source]
Gold-producing provinces with a production development of over 1 have a yearly chance to become depleted (halving gold production). With a production development level of 2 the depletion chance is 0.01% yearly, with higher development levels having higher chances (level 3 has a 0.04% chance, level 4 has a 0.07% chance, level 5 has a 0.12% chance, etc.). Each depletion reduces the province's base production in half (unrounded, so it's possible to get fractional development!), effectively halving the
produced, but reducing the depletion chance by more than four times. The player can see the current chance of depletion by hovering over the production development increase button on the province panel.
The chance of a goldmine depleting each year is presumably given as:
Rounded down to be displayed in the tooltip.
The depletion can only happen once per year and only on the first day of a month which depends on the province id of the gold mine[4].
Base production | Yearly depletion chance |
---|---|
3 | 0.04% |
4 | 0.07% |
5 | 0.12% |
6 | 0.17% |
7 | 0.24% |
8 | 0.31% |
9 | 0.40% |
10 | 0.49% |

Given a gold-producing province with a production development
, over time it will deplete at most (rounded down) times, because a level 1 mine never depletes. Treating a gold-mine as a discrete-time linear system it is possible to estimate the production over a given period of time.A gold-mine in a province with a production development
, is equivalent to a (rounded down)-th order system.The discrete state matrix for a period of a year is:

Colonial nations[edit | edit source]
![]() |
Available only with the El Dorado DLC enabled. |
A colonial nation subject receives no income from gold and instead saves it up and sends periodic treasure fleets to their overlord, as long as their overlord's trade capital is located in a trade node downstream from the trade node the colonial nation's trade capital is located in. If this is not the case, the colonial nations simply collects the gold as normal and pays the normal amount in tariffs.
Privateers may plunder treasure fleets.
Slaves[edit | edit source]
When a country passes the Abolish Slavery Act, all its provinces producing slaves are immediately set to produce
“unknown”. This will also remove any Trade Stations in the province if present, as well as the province modifier “Slave Entrepot”. A new trade good will be randomly reassigned at the beginning of the next month based on the new weights for that province. The
War Against the World Doctrine for pirate republics and
Dominicans holy order disallow
slaves in a similar way.
Coal[edit | edit source]
![]() |
Available only with the Rule Britannia DLC enabled. |
- See also: Coal in the tradegoods table
After the appearance of the Enlightenment Institution, some provinces may change their trade good and produce coal. Coal allows the province owner to build a Furnace in said province, which gives a global +5%
goods produced to the province owner.
Coal can appear in a province that fulfils the following conditions:
- Has Coal as a latent resource
- Has the Enlightenment present
- The owner has embraced the Enlightenment
- One of the following:
- The Province has a
Development of at least 20
- The Province owner has at least 20

Colonies begin with “unknown” trade good and are randomly assigned a trade good after reaching a population of 400 colonists (40%)[5]. The trade good is determined by a system of scripted weights[6]. All possible trade goods are shown by hovering the
“unknown” trade good icon of the province interface.
Trade goods are weighted based on a variety of factors. The most common are geographic restrictions based on terrain, climate, and region, but some trade goods' probabilities are influenced by the culture and even religion (in the case of wine) of the colonizing nation.
Silk will never be produced in a colony in a game with normal or historical nations, and
cloth,
glass, and
paper, while not directly excluded, are likewise precluded by their high
development level requirement.
Coal is a latent trade good and can't directly spawn from colonizing, although it can appear later if the province has coal as latent trade good.
The chance of getting a given trade good in a province is presumably given by
where
is the probability of a specific possible trade good, n is the number of possible trade goods in the province, are all the modifiers for that trade good multiplied with each other, and the sum in the denominator runs over all possible trade goods in the province.If a colony has started to produce a trade good due to growing over 400 settlers, and the colony is later destroyed before becoming a city, the trade good in the province will revert to “unknown” and will be selected randomly in subsequent attempts at colonisation. Once a colony has reached 1,000 settlers and become a city, its trade good is fixed barring a few specific events (such as for
slaves, see above).
List of trade good probabilities[edit | edit source]
This table shows the base weights and various modifying probabilities for each trade good. Note that all provinces get a weighting, since custom setup can cause any province to be uncolonized. In the case of provinces that normally have slaves, the weights determine what it gets if the owner abolishes slavery.
