Frequently asked questions
What does the GDP Calculator compute?
It applies the expenditure approach: GDP equals consumption plus investment plus government spending plus net exports. Enter the four components in the same unit and it returns total GDP in that unit.
What are the four components?
Consumption is household spending, investment is business spending on capital goods, government spending covers public purchases, and net exports are exports minus imports, which can be negative for trade-deficit economies.
Can you give a worked example?
With consumption 1000, investment 500, government spending 300 and net exports 100, all in billions, GDP is 1900 billion.
Does it adjust for inflation?
No. This is nominal GDP from the values you enter. Converting to real GDP requires dividing by a price index or GDP deflator for the period you are studying.
