GDP Calculation

Y = C + I + G + E

where

Y = GDP

C = Consumer Spending

I = Investment

E = Exports - Imports

G = Government Spending

United States GDP 2003

Y = C + I + E + G

$$ in Billions

Consumer Spending = $7605

Investment = $1606

Exports = $1021

Imports = $1508

Government Spending = $2017$7605 + 1606 + (1021-1508) + 2017 = $10,741 (2003)

GDP
