Use official data for publication
This page performs the arithmetic. For national accounts, use official statistical agency data and definitions, because GDP components, deflators and revisions follow formal accounting standards.
Example
If consumption is 1,000,000, investment is 250,000, government spending is 300,000, exports are 150,000 and imports are 200,000, nominal GDP is 1,500,000.
Common mistakes
Imports are subtracted because they are included in spending but produced elsewhere. Do not add imports to exports when using the expenditure approach.
Limitations
This calculator does not replace national accounts data. It does not handle chained prices, seasonal adjustment, revisions, purchasing power parity or country-specific accounting classifications.
