Many Macroeconomics Formulas are used within eRepublik to determine things such as the recommended exchange rate, the gross domestic product, and the unemployment rate. This page contains a list of all known equations used in the game.

In these equations, the symbol "" will represent Gold, and the symbol "¤" will represent the local currency.

#### Recommended exchange rate

The recommended exchange rate (RER) of a currency is the recommended rate of exchange from one currency to another. This formula calculates the RER within the last seven days.

1 = APC × ¤ 10

#### Gross Domestic Product

This formula calculates the gross domestic product (GDP) of a country within the last thirty days.

GDP = C + G + L + S

• C: (Cost of creating a company) × (Number of created companies)
• G: the total Gold invested by the general managers from your country in company upgrades
• S: the total value of gross sales made by companies from your country to internal and external market (S = Gross sales × RER)

#### Unemployment rate

This formula calculates the unemployment rate (U) of a country within the last thirty days as a percentage.

U = (A - E - M) ÷ A

#### Imports

This formula calculates the net imports (IM) of a country in Gold within the last thirty days.

IM = S ÷ RER

#### Inflation

This formula calculates the inflation (I) of a country within the last seven days.

I = ((APC1 ÷ APC2) - 1) × 100
