Expenditure Approach and Value Added are two Measuring the Economy concepts in AP Economics that students often mix up. In short: expenditure approach is the expenditure approach calculates GDP by summing all final spending on goods and services produced within a country.

The expenditure approach calculates GDP by summing all final spending on goods and services produced within a country.
It adds consumption, investment, government purchases, and net exports (exports minus imports). This method reflects total demand in the economy and is the most commonly used way to measure GDP in macroeconomics.
Value added is the value of output minus inputs.
Value added represents the additional value created at each stage of production. It is calculated by subtracting the cost of intermediate goods from the value of output. Value added is used to calculate GDP because it avoids double counting the value of intermediate goods. By summing the value added at each stage of production, we can determine the total value of final goods and services.
