Come On, Understand National Revenue Based On Production Costs With Simple Examples

YOGYAKARTA - Understanding national income based on production costs is a way to calculate the total value of a country's goods and services in terms of costs incurred in the production process.

By understanding this concept, students can see how labor wages, land leases, capital interest, and company profits form national income.

Reporting from the e-Module of the Economy of the Directorate of High School Development - Ministry of Education and Culture, national income is the total amount of income earned by the entire community or economic actors living in a country within a certain period of time, usually one year.

This income includes the value of all goods and final services produced domestically. In other words, the amount of national income is comparable to the value of a country's national product.

National income is influenced by various important factors such as the availability of production factors, skills and labor expertise, technological advances, allocated amounts of capital, and national stability conditions. The higher the efficiency and productivity of these factors, the greater the national income that can be achieved.

Aggregate Demand (AD) or the overall demand is the total number of public requests for goods and services at a certain price level. Meanwhile, Aggregate Supply (US) or the overall offering is the amount of goods and services offered by producers at a certain price level.

Well, it is this balance between demand and supply that can encourage an increase in a country's national income.

Investment has a big role in encouraging national revenue growth. As the level of domestic investment increases, national production capacity also increases.

Consumption is part of the income of the community which is used to buy goods and services to meet the needs of life. Meanwhile, savings are part of income that is not used for consumption.

National income based on production costs is a way to calculate the total income of a country by increasing all costs incurred in the process of producing final goods and services.

This method looks in terms of production costs, namely all expenditures used to create products to be ready for public consumption.

It should be observed, in this approach, what is calculated is only the final value of goods and services, not the value of each stage of production. This is important to avoid double counting.

Examples of cases:

The price of one car unit is IDR 300 million. This price includes a production cost of IDR 150 million, which is partly revenue for tires, steel, and other components. If all the value of each production stage is calculated, then the total value of income will be calculated repeatedly and does not reflect the actual figure.

Therefore, the production cost approach only takes into account the costs that are actually incurred to produce final goods and services, such as labor wages, land leases, capital interest, and company profits.

Thus, in this way, the value of national income can more accurately describe how production activities contribute to the economy of a country.
