What GDP Measures At its core, GDP sums the market value of all final goods and services produced within a country over a specified period. Calculated three ways—production (value added), expenditure (consumption + investment + government spending + net exports), and income (wages + profits + taxes minus subsidies)—the three methods should, in principle, yield the same number. This circular consistency is GDP’s elegance: it ties production, spending, and income into one measurable flow of economic activity.
