How is GDP calculated?

Question

How is GDP calculated for an economy? I’d like to understand the main components used in the calculation and how consumer spending, investment, government spending, and trade contribute.

William · Answer

GDP is primarily calculated using the expenditure approach, which sums up total spending in an economy. This includes consumer goods, business investments, government spending, and net exports. Essentially, you add up all the money spent on final goods and services produced domestically during a specific period. It’s less about counting individual transactions and more about tracking the final value of production to gauge overall economic health accurately.
