How to Check Employee and Employer Burden for the Four Major Social Insurances at a Glance Using a Calculator

1. Basic Concepts and Components of the Four Major Social Insurances

The four major social insurances deducted from your monthly salary consist of the National Pension, Health Insurance, Employment Insurance, and Industrial Accident Insurance, forming a social security system managed by the state. The National Pension is structured so that you pay premiums during your enrollment period to receive a pension later, ensuring a stable life after retirement or in old age. Health Insurance plays a crucial role in alleviating the financial burden on households when unexpected illnesses or injuries result in high medical bills. Employment Insurance supports re-employment and vocational skill development when workers become unemployed, while also serving as the basis for various benefits such as parental leave. Finally, Industrial Accident Insurance is a system that guarantees treatment and compensation for work-related injuries, with the full cost borne by the employer. As such, each insurance is directly related to our daily lives and is automatically calculated based on set rates, deducted from our salaries every month.

2. Understanding the Burden Ratios for Employees and Employers

While many of the four major social insurance premiums are split equally between employees and employers, the burden ratios vary slightly depending on the type of insurance. For the National Pension, 9 percent of the total monthly remuneration is paid, with employees and employers each bearing 4.5 percent equally. Health insurance premiums are also calculated based on the monthly remuneration and are structured so that employees and employers each pay half. For Employment Insurance, while employees and employers share the burden at a certain ratio considering rates such as unemployment benefits, the employer additionally bears the costs for employment stability and vocational skill development programs. As mentioned earlier, for Industrial Accident Insurance, employees bear no cost at all, and the employer pays the full amount. Therefore, when employers hire staff, they must budget considering not only the base salary paid to the worker but also these employer-borne costs.

3. Checking Take-Home Pay Using a Simple Calculator

Using a Four Major Social Insurance calculator allows you to easily derive the exact take-home pay simply by entering your taxable salary, without having to solve complex formulas yourself. By using internet portal sites or the mock calculation tools from the Four Major Social Insurance Information Linkage Center, National Pension and Health Insurance premiums are automatically calculated with just a few pieces of information. For example, for an office worker with a monthly salary of 3 million won, the total employee-borne costs (National Pension, Health Insurance, and Employment Insurance) amount to approximately 9.4 percent of the total salary. After deducting income tax and local income tax, the actual take-home pay deposited into the bank account is slightly lower than expected. If there are non-taxable salary items such as meal allowances or self-driving subsidies, the taxable amount changes, so it is important to distinguish and enter these parts accurately when using the calculator.

4. Enrollment Criteria for Part-time and Short-time Workers

For part-time jobs or short-time workers with a short weekly scheduled working time, it is necessary to carefully consider whether they fall under the scope of the four major social insurance enrollment. National Pension and Health Insurance are mandatory only if the scheduled working time per month exceeds a certain number of hours; otherwise, they may be excluded. For Employment Insurance, the principle is that enrollment is required if the working hours per month exceed a certain standard, regardless of the employment type, but some exceptions apply to those working less than 15 hours a week. For workplaces employing daily workers or short-time workers, inaccurate calculation of working hours can lead to disadvantages such as paying additional levies later. Therefore, it is wise to clearly state the weekly holiday allowance and scheduled working hours when drafting employment contracts and to run a simulation in advance to check if they meet the four major social insurance enrollment criteria.

5. Labor Cost Budget Simulation for Employers

For business owners, the total labor cost expenditure, including the four major social insurances, is a much more important management indicator than the take-home pay received by employees. When planning to hire one more employee, an accurate hiring plan can only be made by considering not only the base salary but also the four major social insurance premiums and severance pay accruals that the employer must pay monthly. Industrial Accident Insurance premiums have different rates applied depending on the risk level of the industry, so expenditure costs differ depending on whether it is a manufacturing business or a service business centered on office work. By using a mock calculator for employers, you can calculate the total social insurance premiums paid monthly based on the total remuneration of each employee, allowing for smooth management of cash flow. It is necessary to develop the habit of periodically checking labor cost expenditures through calculators to avoid unexpected costs during tax filing periods or settlement times.

6. Smartphone Inquiry and Future Financial Management Directions

Recently, it is possible to easily check one’s four major social insurance payment history and estimated pension amount anytime and anywhere through smartphone apps or mobile web pages. In the past, one had to visit public institutions in person or go through complex procedures, but now one can transparently check their enrollment history with just a few touches. As more office workers seek to systematically prepare for old age, more people are virtually checking the National Pension amount they will receive after retirement in advance. Although the amount deducted from monthly salaries may feel like a loss, it ultimately serves as a solid social safety net for my future self and family. As various financial calculation tools and mobile simple calculator functions are expected to become more convenient in the future, it is recommended to actively utilize them according to your salary conditions.
