Calculate nominal GDP using the expenditure approach (C + I + G + X − M)
This GDP calculator computes nominal Gross Domestic Product using the expenditure approach, which sums consumption, investment, government spending, and net exports (exports minus imports). It also calculates GDP per capita and shows the percentage contribution of each component.
Nominal GDP measures the value of goods and services at current market prices, while real GDP adjusts for inflation to reflect actual economic growth. This calculator computes nominal GDP. To derive real GDP, divide nominal GDP by a price deflator index.
GDP (expenditure approach) has four main components: Consumption (C) — household spending on goods and services; Investment (I) — business spending on capital goods; Government Spending (G) — government expenditures; and Net Exports (X − M) — exports minus imports. Each component provides insight into different sectors of the economy.
