Four Major Insurances Calculator: How to Check Your Take-Home Pay, Gross Salary, Net Salary, and Deductions
1. What Are the Four Major Insurances and Why Are They Deducted Monthly?
This term collectively refers to the social security systems that the state mandates for workers to maintain a stable social life. When you start a job and receive your payslip, you will invariably see four items listed: National Pension, Health Insurance, Employment Insurance, and Industrial Accident Insurance. Notably, Industrial Accident Insurance is fully borne by the employer, so it is not directly deducted from the worker’s salary. The other three insurances, along with income tax and local income tax, are automatically deducted from the monthly salary to determine the take-home pay. Since these are essential deductions that every office worker cannot avoid, it is important to understand the structure accurately. While it may feel like a waste of money to see it deducted every month, it serves as a valuable safety net for preparing for retirement and the risk of unemployment. Young professionals starting their first job are often surprised to see a significant portion of their salary disappear. However, understanding why this system exists and why money is leaving your bank account helps greatly in making financial plans. The insurance premiums paid diligently during your employment will return as a solid support when you retire or get injured. Therefore, it is necessary to pay attention to how the monthly charges are calculated. Instead of simply complaining that too much tax is being taken, a shift in perspective is required to view these as essential costs for protecting your assets.
The Four Major Insurances are state-operated social security systems and are essential deductions for the worker’s future.
2. Understanding the Calculation Structure of National Pension and Health Insurance
National Pension is calculated by multiplying the subscriber’s standard monthly income by a certain rate, and the rate may be adjusted each year according to policy changes. Generally, the worker and the company share the burden equally, so the payslip lists half of the total amount. For example, if an office worker has a monthly salary of 3 million won, the National Pension deduction is calculated based on the prescribed rate and deducted from the salary. Since new insurance rates are applied whenever the calculation criteria change, it is safer to use tools that reflect the latest information. Health Insurance is also shared equally between the worker and the company, with Long-Term Care Insurance premiums added and charged on top. Health Insurance premiums cover not only medical benefits but also the costs of caring for long-term care recipients. Since all these items are automatically reflected when calculating the salary for office workers, it is easy to overlook the details if you do not check them carefully. Occasionally, results may vary slightly between different calculators due to the application of outdated rates or differences in the order of deductions. Therefore, it is essential to use a reliable, up-to-date program and compare it with your own salary. Knowing the exact calculation structure allows you to verify whether there are any errors in the statement issued by your company.
National Pension and Health Insurance are shared equally between the worker and the company, and the rates may change every year.
3. The Impact of Employment Insurance and Income Tax on Take-Home Pay
Employment Insurance is a system that helps with re-employment and vocational ability development in case of unemployment, and it is shared between the worker and the employer. Since Industrial Accident Insurance is fully borne by the employer, it is not deducted from the worker’s salary; only the Employment Insurance premium is deducted from the monthly salary. Once worker’s income tax and local income tax are added to these, the final take-home pay that we actually see in our bank account is determined. No matter how high the gross annual salary is, the actual amount in hand can differ significantly after all these deductions are made. Therefore, when preparing for a job change or negotiating a salary, you should base your decision on the net take-home pay rather than just the gross amount. It is common to see office workers who are happy about a salary raise but are disappointed to find that the actual increase in their bank balance is minimal. This is a natural phenomenon caused by the increase in income tax and Four Major Insurances deductions as the tax bracket changes.

If you enter relevant keywords into an internet portal site, you will find tools that anyone can use easily.

The actual take-home pay deposited into your bank account is determined only after Employment Insurance and various income taxes are deducted.

5. Why Calculator Results Differ from Actual Payslips
Even when the take-home pay matched when using the calculator, the amount on the actual statement may sometimes differ slightly. The biggest reason for this difference is that the scope of non-taxable allowances applied varies slightly from company to company. Non-taxable items such as meal expenses or self-driving allowances are excluded from the scope of tax and insurance premiums, thus affecting the take-home pay. Additionally, if there are variable amounts that change monthly, such as overtime pay or holiday work pay, there will be a difference from values calculated based on a fixed monthly salary. Therefore, for an accurate comparison, you must carefully verify whether non-taxable items are accurately reflected in addition to your fixed salary. Occasionally, using sites that apply outdated rates can lead to errors because they do not reflect the criteria revised each year. Therefore, it is most important to choose a trustworthy platform and perform calculations according to the latest criteria. If the discrepancy between the amount on the payslip and the estimated amount is too large, it is a good method to contact the HR department directly. This is because it is possible that a simple error occurred in the process of tax withholding or insurance premium calculation. When you take an interest in whether your hard-earned money is being securely protected, you can successfully take the first step in financial management.
There may be differences between calculation results and actual statements due to the presence of non-taxable allowances, variable allowances, or the application of outdated rates.
