What is GDP?
Gross Domestic Product (GDP) measures the total monetary value of all goods and services produced within a country over a given period. The expenditure approach calculates it by summing major spending categories.
The Formula
GDP = Consumption (C) + Investment (I) + Government Spending (G) + Net Exports (Exports – Imports). This is the standard expenditure-method formula used by economists and statistical agencies worldwide.
