There are two kinds of GDP numbers prevalent — nominal GDP and real GDP. The nominal GDP measures the value of all goods and services produced at current prices, and does not take inflation (which leads to an erosion of the value of money) into account. Real GDP measures the value of all goods and services produced against that of an agreed-upon base year’s prices.
