Korea social insurance calculator — employee and employer shares (2026)
On a monthly pay of ₩3,000,000, the employee's share of Korea's four social insurances is ₩291,520 and the employer's is ₩299,020 (under 150 workers, industrial accident insurance not included). Enter a pay to see each premium split in two, at the 2026 rates.
An estimate at 2026 rates. Actual premiums follow the amount reported to each agency and the yearly settlements, and can differ.
How the premiums are worked outHow this works
The employee's four premiums
Each premium starts from the month's pay without tax-free items. National Pension is 4.75% of that pay cut to the thousand won and kept between 410,000 and 6,590,000 won (the limits from July 2026; they change every July). Health insurance is 3.595%, long-term care is 13.14% of the health premium, and employment insurance is 0.9%.
Each is cut below 10 won. This page runs the same code as the salary take-home calculator on this site, so the employee's figures match it to the won. The social insurance information centre's own example, 2,000,000 won a month, gives 71,900 won health and 9,440 won long-term care, and so does this page.
What the employer pays
For pension, health, long-term care and the unemployment-benefit part of employment insurance, the employer pays the same amount as the employee; the official calculator shows the two shares as equal. So the employer's first four lines repeat the employee's.
The employer alone also pays the employment security and job skills development premium, at a rate set by company size: 0.25% under 150 regular workers, 0.45% for a firm of 150 or more that qualifies as a priority support firm, 0.65% for 150 to 999, and 0.85% for 1,000 or more or for work done directly by the state or a local government (Enforcement Decree of the premium collection act, Article 12).
Industrial accident insurance
Industrial accident insurance is paid by the employer only, and its rate differs by kind of business: the law has the Ministry of Employment and Labor set it every year for each kind, from the past three years of claims. There is no single number that fits every workplace, so this page does not guess one.
If you know your rate from the yearly notice or the bill from the Korea Workers' Compensation and Welfare Service, type it in and the page adds the premium to the employer's total. Left empty, the line says “by industry” and the total leaves it out.
Rounding, and what is not covered
The official calculator states that health and long-term care premiums drop the last won digit. The pension and employment agencies' pages read on 30 October 2026 did not state a rule, so the same 10-won cut is applied to them and to the employer-only premiums; the difference is under 10 won a line.
The figures are what a month's pay alone gives. Premiums are billed on the pay reported to each agency and settled once a year, and income other than pay can add health premiums, so a real bill can differ. These are Korea's rules for work in Korea; other countries have their own systems. What you type stays in this browser.
What does an employee on 3,000,000 won a month cost the company in social insurance?
299,020 won a month at a company under 150 workers, plus industrial accident insurance at the rate for its industry. The employee pays 291,520 won out of the pay.
Does the company pay the same as the employee?
For pension, health, long-term care and the unemployment-benefit part of employment insurance, yes: the same amount each. The company also pays the employment security and job skills premium alone (0.25% under 150 workers, 7,500 won on 3,000,000 won) and industrial accident insurance.
Why is industrial accident insurance not filled in?
Because its rate depends on the kind of business and is set every year; one number would be wrong for most workplaces. Type the rate from your notice or bill into “Industrial accident rate (%, optional)” and the page adds it.
