Frequently asked questions
What is the GDP formula?
GDP = C + I + G + NX, where C is consumption, I is investment, G is government spending, and NX is net exports (exports − imports).
What is net exports?
Exports minus imports. It's negative when a country imports more than it exports, which subtracts from GDP.
