Growth Rate

Growth Rates by Country

 * Germany, Britain, France, and Italy
 * 10% in 1940 YSS, increasing by 10% per year until reaching the country's maximum Growth Rate:
 * Germany: 50%
 * Britain: 40%
 * France: 30%
 * Italy: 20%
 * Russia
 * Russia's Growth Rate % is determined in the Year Start Sequence, and equals the level of the RGT level
 * If Russia and Germany are at war, Russia's Growth Rate is 50%
 * US and Japan: 50%
 * China
 * China's Growth Rate is 0%, and may not increase

Positive Growth
At the start of each Year Start Sequence before calculating BRP levels, each country's unspent BRPs from the previous year are multiplied by its Growth Rate, rounding down, and the result is added to the country's BRP base. The unspent BRPs are lost.
 * Example: Russia has 5 unspent BRPs from the previous year, with a Growth Rate of 50%. In the Year Start Step, Russia's BRP Base is increased 2 (50 x 50%, rounding down), and the unspent BRPs are lost.

Negative Growth
At the start of each Year Start Sequence, if a country has negative BRPs from the previous year (such as due to losing territory after spending all of its BRPs), the negative amount is multiplied by the country's Growth Rate, rounding up, and the result is subtracted from the country's BRP base. The remainder of the BRP deficit is then carried over to the new year, and deducted from the country's new BRP level.
 * Example: Germany has a deficit of 4 BRPs from the previous year due to losing territory in the previous Allied Winter turn. It has a Growth Rate of 25%.  Germany's BRP base is reduced by 1 (4 x 20%) and, its BRP levels for this year are reduced by 3 (the remainder of the deficit).

Neutral Major Powers and Unspent BRPs
If a major power is neutral, the BRP value of any unbuilt ground or air units are deducted from its unspent BRPs when determining BRP Growth.
 * Italy, Russia, the United States, and Japan begin a campaign as neutral major powers. They remain neutral until they are at war with another major power.
