## 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.

The basic salary of civil servants and public employees is calculated by coefficient

### 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

Product-based salary is a payment method based on the number of products that workers complete in a certain period of time. This form of salary is often applied to workers working in the production and manufacturing industries.

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

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.

Salary calculation is based on the employee's actual working time

Advantages of calculating salary over time:

• Transparent and easy to apply: Time-based salary calculation form is simple, easy to understand and easy to implement for both employees and employers.
• Stable income: Employees can be assured of a stable monthly income, not affected by fluctuations in job performance or the market.

Disadvantages of the time-based salary calculation method:

• 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.

The weekly salary calculation method means that businesses pay salaries once a week, that is, every 7 days. This helps workers easily manage their weekly finances and avoid difficulties due to financial shortages.

Salary calculation formula:

Salary paid for 1 week = (Monthly salary x 12 months) / 52 weeks

For example: Mr. B agreed to a monthly salary of 10,000,000 VND and the company paid him weekly. So Mr. B's weekly salary is: 10,000,000 x 12 / 52 = 2,307,692 VND.

Advantages of the 7-day salary payment method:

• Flexible and responsive: Weekly salary payment allows timely adjustment of salary based on the actual situation of work and employee performance.

• Limited scope of application: This form of payment is only suitable for certain types of jobs, especially jobs that are seasonal or unstable.

### How to calculate salary by working day

The daily wage calculation is suitable for short-term or special jobs. In this method, wages are determined and paid after each working day, ensuring workers receive accurate wages for the actual number of days worked.

If the contract agrees to pay salary by day of the month:

Salary paid for 1 working day = Salary for the whole month: Number of normal working days in the month

If the contract agrees to pay wages by day of the week:

Wage paid for 1 day = Weekly wage: Number of working days in the week

For example: Ms. A has a labor contract with a salary of 12,000,000 VND, working 24 days/month. Daily salary will be: 12,000,000 / 24 x 12 = 500,000 VND.

Wage paid for 1 hour = Daily wage: 8 hours

This form of payment is often applied to jobs that have a clear nature and quantifiable output products. For example, construction workers, product sales staff, etc.

Salary calculation formula:

Contract salary = Contract salary x Job completion rate

For example: Furniture company A hires Mr. B to complete interior products as requested. The salary is 15,000,000 VND and needs to complete 15 products this month. Mr. B completed 12 products, the completion rate was 80%. So Mr. B's salary is: 15,000,000 x 80% = 12,000,000 VND.
