There are 3 key means of calculating GDP: first, by simply adding up what everybody got within a year (referred to as the income approach) or simply by adding up what everybody spent within a year (the cost method). Logically, the two steps should arrive at approximately the same total.

The income approach, which may be known as GDP(I), is calculated by adding up total compensation to workers, gross earnings for integrated and non-incorporated companies, and taxes less any subsidies. The cost system is a common strategy and can be calculated by adding overall consumption, investment, government spending, and net exports.

Ultimately, GDP may equivalently be quantified depending on the value of products or services produced within a market within the course of this year (the manufacturing or output ). Because economic output necessitates is, consequently, swallowed, these 3 methods for calculating GDP all arrive at precisely the same price.

Generally, the following simplified equation can be employed to calculate that a Country's GDP:

GDP = C + G + I + NX


  • C = ingestion;
  • G = government spending
  • I = investment; and
  • NX = net exports.
