Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use national-accounting definitions and one currency/period. Government transfers are not government purchases.
Example Calculation
- Consumption: 500
- Investment: 200
- Government purchases: 250
- Exports: 100
- Imports: 150
Consumption = 500; Investment = 200; Government purchases = 250; Exports = 100; Imports = 150. The primary result is 900.
Frequently asked questions
How do I use this calculator?
Enter consumption, investment, government purchases, exports, imports. The result updates automatically. Use Reset to restore the example values.
What method does it use?
GDP=C+I+G+exports−imports.. Use national-accounting definitions and one currency/period. Government transfers are not government purchases.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
