Expenditure Method: By adding up all of the costs associated with purchasing national output, this method determines the national income. The Expenditure method is a method for calculating GDP that takes into account net exports, investment, government spending, and consumption. It is the most prevalent method for estimating GDP. It specifies everything that must be added to the total value of all finished goods and services produced over a certain period of time by the private sector, including consumers and private businesses, as well as government spending within the borders of a particular nation. This strategy produces ostensible Gross domestic product, which should then be adapted to expansion to bring about the genuine Gross domestic product.

Consumption is a reference to spending. Demand is an alternative term utilized within economics to define consumer spending. The term "aggregate demand" refers to the economy's total spending, or demand. Because of this, the formula for calculating aggregate demand and the GDP formula are actually the same; As a result, aggregate demand and Expenditure GDP must both fall or rise simultaneously. However, this theoretical similarity is not always present in the real world, particularly when looking at GDP over the long term. Short-run aggregate demand only takes into account total output at a single nominal price level, which is the average of the current prices of all goods and services produced by the economy. After accounting for the level of the price, aggregate demand does not, in the long run, equal GDP.

The most common method for estimating GDP, which is a measure of the economy's output produced within a country's borders regardless of who owns the means of production, is the expenditure method. Under this approach, the sum of all expenditures on final goods and services is used to calculate GDP. GDP is determined using four primary aggregate expenditures: household consumption, business investment, government spending on goods and services, and net exports, which are the sum of exports and imports.

There are four production factors: land or natural resources; labor or human resources; produced capital or means of production; and businesses or organizations.

Rent is the payment for the use of land. Wages are the payment for using labor, and interest is the payment for using capital. Primary factors of production are land, labor, and capital, and their contractual payments are referred to as factor Incomes. The profit is the surplus, or what remains after these primary factors have been paid. The producer receives a profit from this residual income.

As a result, there are four possible sources of income for participation in the production process: profit, interest, rent, and wages. When we talk about national income, we're referring to the total of all rent, wages, interest, and profit that each citizen earned during a given time period from the production process. This is called the factor payments total.
