How much does management cost account for operating income to be reasonable?

10%~ 12%。

Generally speaking, the ratio of management expenses to operating income can be between 10%- 12%, but this is only a rough reference range. If the company is in the period of development or scale expansion, it may be necessary to temporarily increase the proportion of management expenses to invest more resources to promote the company's development. After the company's business is stable, the proportion of management expenses can be stabilized at a relatively low level to save costs and improve the return on investment.

The proportion of management expenses to operating income in different industries may also be different. For example, in industries with high marketing costs, such as hotels and restaurants, the proportion of management fees is usually higher than other industries.
