Farmers who grow spinach for household consumption or to supply the market to generate income have already used labor, time, land, water, tools, and various factors of production. All of these have value and are part of the capital of production. Therefore, collecting data on various costs such as seeds, fertilizers, pesticides, labor, water, packaging materials and transportation to the consumer or market is essential to have accurate information to enter into the economic calculation process in production. It helps farmers to calculate the economy by:

• Calculate the capital and unit price of spinach to be sold to make a profit
• Be able to decide how much spinach to plant, when to plant and which technique to use to maximize profit
• Avoid capital losses from improper management.

Economic analysis in spinach cultivation is both a tool and an important step that helps to see or measure the value of investment and returns in order to determine the correct and appropriate production and business plans. In addition, it also helps producers to have stable market integration and move towards higher levels of competition.
