Basic salary calculations

Basic salary plays an important role in workers' income. This is the basis for calculating allowances, social insurance and other benefits. The current basic salary calculation is different between officials, civil servants, public employees and employees working under labor contracts.

Basic salary of officials, civil servants and public employees

Salary calculation formula:

Basic salary = Base salary x Salary coefficient

According to Article 3 Resolution 69/2022/QH15 and Decree 24/2023/ND-CP, the basic salary coefficient is divided as follows:

  • Intermediate base salary coefficient: 1.86 million VND/month 
  • Basic salary coefficient for College level: 2.10 million VND/month 
  • Basic salary coefficient for university level: 2.34 million VND/month 
  • Base salary coefficient for master's degree: 2.67 million VND/month 
  • Base salary coefficient for PhD level: 3.00 million VND/month 

For example: For a civil servant with a university degree, the salary coefficient is 2.34, their basic salary is: 1.8 million VND/month x 2.34 = 4,212 million VND/month.

Basic salary of employees working under labor contracts

For employees working under labor contracts for businesses and individuals, the basic salary is agreed between the employee and the employer. However, this salary is not lower than the regional minimum salary as prescribed by the Government.  

The current regional minimum wage is specified in Article 3 Decree 38/2022/ND-CP as follows:

Region

Minimum salary by month

Minimum hourly wage

Region I

4,680,000 VND/month

22,500 VND/hour

Region II

4,160,000 VND/month

20,000 VND/hour

Region III

3,640,000 VND/month

17,500 VND/hour

Region IV

3,250,000 VND/month

15,600 VND/hour

The application of regional minimum wages ensures that workers will receive a minimum wage sufficient to cover basic living expenses and maintain a stable standard of living. At the same time, this also helps protect the rights of employees in salary agreements with employers.

How to calculate product-based salary

Salary calculation formula:

Salary calculated by product = Product unit price x Number of completed products

For example: If a worker completes 200 products with a unit price of 50,000 VND/product, they will receive 10,000,000 VND in the month

salary calculation formulas

Product-based wages help increase productivity

Advantages of calculating salary by product:

  • Increase motivation and performance: Encourage employees to work hard, improve productivity and product quality to maximize personal income.
  • Simplify management: Easily track and evaluate work efficiency based on the number of completed products, reducing the burden of working time management.

Disadvantages of the product-based salary calculation method:

  • Work pressure: Unreasonable product norms can create great pressure, leading to overwork, negatively affecting health and product quality.
  • Income inequality: Less skilled and productive workers may have difficulty maintaining a steady income, creating income disparities between individuals.

How to calculate salary by time

The method of calculating salary based on the employee's actual working time is based on determining the salary based on the total number of actual working hours in a certain period of time, usually monthly. The specific salary is usually agreed upon and clearly stated in the labor contract between the employee and the business.

Salary calculation formula:

Monthly salary = Negotiable salary / Number of working days in the month x Number of actual working days

If the enterprise fixes the number of working days in the month to 26, then calculate as follows:

Monthly salary = Negotiable salary / 26 x actual number of working days

For example:

  • An employee has an agreed salary of 12,000,000 VND/month, working 22 days out of 23 working days in the month.
  • This employee's actual monthly salary will be: 12,000,000 VND / 23 days/month x 22 days = 11,478,261 VND.

Note: The number of working days in a month and the actual number of working days may vary depending on business regulations and labor laws.

  • Reduced motivation to work: Fixed salary does not reflect true capacity and work efficiency, which can reduce the motivation and creativity of workers.
  • Reduced overall efficiency: Regularly paying even inefficient workers can create injustice and reduce the overall productivity of the business.

How to calculate salary by month

Monthly salary calculation is the form of salary payment once a month or once every half a month. They are fixed in the labor contract between the employee and the enterprise. This method is popular and convenient for managing employees' personal salaries and managing the company's salary fund.

Salary calculation formula:

Monthly salary = [(Salary + Allowances if any) / Standard number of working days] x Actual number of working days.

In which, the standard number of working days is the number of administrative working days in the month. If an enterprise regulates work from Monday to Friday, with Saturday and Sunday off, the standard number of working days is 22. 

For example: If an employee works from Monday to Friday, has Saturday and Sunday off, and the month has 30 days, including 26 working days and 4 Sundays off. If this employee works 22 days in a month, the salary received will be: 10,000,000 / 26 x 22 = 8,461,538 VND.
