About the GDP Calculator
This calculator computes Gross Domestic Product, GDP per capita, and economic growth rates. You enter spending components or total output figures, and the tool returns national GDP along with per-person and growth values. Results update as you type.
It applies the standard expenditure approach formula: GDP = C + I + G + (X - M), where X stands for exports and M for imports. GDP per capita divides total output by population. Growth rates compare GDP across two periods as a percentage change. Enter all values in the same currency and from the same year to keep results consistent.
- Select the expenditure approach and enter consumption, investment, and government spending.
- Add exports and imports to complete net exports.
- Enter population and prior-year GDP to see per capita income and the growth rate.
