How it works
Imports correct the production boundary
Imports are subtracted because consumption, investment and government purchases can already include foreign production. Reducing imports alone while holding those linked spending entries unchanged describes a different scenario, not the accounting effect of simply removing an imported purchase.
Keeping national-account components separate
The expenditure and income-based modes organize economic activity using different accounting relationships. Match each input to the field definition so that the same amount is not counted more than once. Use figures from a consistent period and unit scale. Adding components calculates the entered accounting total; it does not independently verify official data or measure every aspect of living standards.
Expenditure approach: formula and assumptions
GDP = consumption + investment + government purchases + exports − imports.
All components must use the same currency, scale, accounting period, and national-accounts definitions.
Income-based national accounts: formula and assumptions
GDI = net domestic factor income + taxes less subsidies + capital consumption.
The national basis adds net payments abroad to move to domestic income. All amounts must use compatible net/gross definitions, currency, scaling and period. The discrepancy reconciles income to expenditure GDP.
Worked example
Using the Expenditure approach example:
- Private consumption
- 14000
- Investment
- 4000
- Government purchases
- 4000
- Exports
- 3000
- Imports
- 3500
GDP = consumption + investment + government purchases + exports − imports.
Example result
Nominal GDP: 21,500

Common questions
Why must all national-account components use compatible definitions?
Mixing net and gross amounts, overlapping income categories or different periods can double-count values or omit required adjustments.
How does the income mode distinguish national from domestic income?
National-basis inputs are adjusted using entered payments abroad minus receipts. The statistical discrepancy then reconciles the modeled domestic income with expenditure GDP.
