📊 GDP Calculator – Expenditure Approach
What is GDP?
Gross Domestic Product (GDP) measures the total monetary value of all finished goods and services produced within a country’s borders in a specific time period. It is one of the most important indicators of a nation’s economic health.
How to Calculate GDP (Expenditure Approach)
The expenditure method adds up all the spending on final goods and services in an economy. The formula is:
- C (Consumption): Household spending on goods and services.
- I (Investment): Business spending on capital, inventories, and residential construction.
- G (Government Spending): Government expenditures on goods and services.
- X (Exports): Goods and services sold to other countries.
- M (Imports): Goods and services purchased from other countries (subtracted because they are not produced domestically).
Example Calculation
Suppose a country has:
Consumption = $5,000 billion
Investment = $1,200 billion
Government Spending = $2,000 billion
Exports = $800 billion
Imports = $600 billion
Then GDP = 5,000 + 1,200 + 2,000 + (800 − 600) = $8,400 billion.
