What are Korean Social Insurances?
The four major insurances refer to Korea's social insurance system: National Pension, National Health Insurance, Long-Term Care Insurance, and Employment Insurance. Full-time employees and qualifying part-time workers are required to enroll, with the employee and employer each paying about half (Industrial Accident Insurance is 100% employer-paid and is excluded from this calculator). As of 2026, the employee share is 4.75% for National Pension, about 3.595% for Health Insurance, about 12.95% of the health premium for Long-Term Care, and 0.9% for Employment Insurance. National Pension rose from 9% (4.5% employee share) to 9.5% (4.75%) starting 2026 under a pension reform bill passed by the National Assembly in March 2025, and will keep rising 0.5 percentage points per year until it reaches 13% in 2033. The employer pays the same amount for the first three; the employer's Employment Insurance share is set separately at 1.05%–1.65% depending on workplace size. National Pension has monthly income upper and lower bounds (approx. KRW 410K–6.59M for the second half of 2026), so premiums are calculated only within this band. Health Insurance is based on the monthly salary with its own upper limit. Non-taxable items (meal allowance up to KRW 200K/month, vehicle allowance up to KRW 200K/month, etc.) are excluded from the premium base. This calculator is for workplace-insured employees. For locally-insured persons (self-employed, freelancers), a different formula applies and this calculator may not be accurate. Verify actual premiums via the Four Major Insurance Information Center, National Health Insurance Service, or National Pension Service.
When is this calculator useful?
Interviews and salary review
Check how much of the gross salary offered by a company will be deducted as social insurance before it lands in your account. Use together with the take-home pay calculator.
Leveraging non-taxable allowances
Increasing non-taxable items like meal allowances lowers the premium base and reduces your share. Simulate the effect against your company's pay policy.
Workplace → local insurance transition
Estimate the change in burden when transitioning from workplace insurance to local insurance after resignation or starting a business. Local-insurance figures require a separate simulator.
Foreign worker enrollment
Foreigners' enrollment in the four insurances depends on nationality and visa status. Use this calculator to estimate the employee share when enrolled; check exemption eligibility with your HR team.

How to read the result
The result shows the following items. • Taxable standard income: salary minus non-taxable items, used as the premium base. • National Pension: 4.75% of standard income (within monthly upper/lower bounds). • Health Insurance: about 3.595% of the monthly salary. • Long-Term Care: about 12.95% of the Health premium. • Employment Insurance: 0.9% of standard income. • Employee total: sum of the four items. • Employer total (reference): same amount + Industrial Accident (100% employer) + Employment Insurance employer share. Premiums may change at the annual base-salary recalculation (July). Mid-year salary changes are reflected through a separate procedure.
Worked examples
KRW 2M monthly taxable compensation
Assume monthly taxable compensation of KRW 2M. ① National pension = 2M × 4.75% = KRW 95,000 ② Health insurance = 2M × 3.595% = KRW 71,900 ③ Long-term care = health insurance × 12.95% = KRW 9,311 ④ Employment insurance = 2M × 0.9% = KRW 18,000 ⑤ Total employee share = KRW 194,211
KRW 7M monthly compensation (national pension cap applies)
Assume monthly taxable compensation of KRW 7M — above the national pension income cap of KRW 6.59M (H2 2026). ① National pension = 6.59M (capped) × 4.75% = KRW 313,025 (calculated on the cap, not the full 7M) ② Health insurance = 7M × 3.595% = KRW 251,650 (health insurance has a much higher cap, so the full amount applies) ③ Long-term care = 251,650 × 12.95% = KRW 32,589 ④ Employment insurance = 7M × 0.9% = KRW 63,000 ⑤ Total employee share = KRW 660,264 Since national pension is capped regardless of how much higher your income goes, social insurance takes up a shrinking share of income for higher earners.
Things to keep in mind
- Industrial Accident Insurance is 100% employer-paid and is excluded from the employee share. In case of an accident, the worker is covered with no out-of-pocket premium.
- National Pension and Health Insurance have income upper/lower bounds, so very high or very low salaries are capped at the bounded premium.
- Non-taxable items (meal, vehicle, childbirth/childcare allowances) vary by company policy. Check the non-taxable breakdown on your payslip.
- Locally-insured persons (self-employed, freelancers) have premiums based on income, property, and vehicles. This calculator is not accurate for them — use the NHIS simulator.
- The Duruunuri social insurance subsidy (for low-wage workers at workplaces with fewer than 10 employees) covers up to 80% of pension and employment insurance contributions. This calculator does not reflect the subsidy.
- Foreigners may be exempt from some of the four insurances depending on nationality, visa status, and social security agreements. Confirm with HR or the National Pension Service.
Frequently Asked Questions
- What are the 4 major social insurances?
- National pension, health insurance, long-term care insurance, and employment insurance. For workplace subscribers, the employee and employer each pay a share, based on taxable monthly compensation.
- Who pays the employer share?
- The employer withholds the employee's share from monthly pay and remits it together with the employer's share to the integrated collection agency (National Health Insurance Service). Employees never pay this directly.
- Why is industrial accident insurance excluded from the calculation?
- Industrial accident insurance rates vary hugely by industry — from 0.7% (office work) to 37% (mining) — and it's paid 100% by the employer, so it's never deducted from an employee's pay. Since this calculator only shows the employee's own share, industrial accident insurance isn't reflected. In the event of a workplace accident, employees are covered with no out-of-pocket cost.
- Does the employer employment insurance rate vary by company size?
- Yes. The employer's share of employment insurance varies by company size: 1.55% under 150 employees, 1.75% for 150-999, and 2.05% for 1,000+ or public sector. This calculator assumes under 150 employees.
- What is the Duruunuri social insurance subsidy?
- A government program that covers up to 80% of national pension and employment insurance premiums for low-wage employees (roughly under KRW 2.7M/month) at workplaces with fewer than 10 employees. The employer applies and settles this — it isn't reflected here. Ask your HR team if you qualify.
- Do foreigners have to enroll in the four insurances?
- Foreigners working full-time in Korea are generally required to enroll. However, nationals of countries with a social security agreement with Korea (US, Canada, Germany, Japan, etc.) can be exempted from national pension by submitting proof of home-country coverage. Check with HR or the National Pension Service for details.
- Do premium rates increase every year?
- Health insurance and long-term care rates are set annually by the Ministry of Health and Welfare and have trended upward in recent years. The national pension rate was fixed at 9% (4.5% employee share) since 1998, but a pension reform bill passed in March 2025 raises it 0.5 percentage points every year starting 2026, reaching 13% (6.5% employee share) by 2033. As of 2026 it stands at 9.5% (4.75% employee share). Check the current year's official notices for exact figures.
- If my salary changes, does my premium change immediately?
- Health insurance is reconciled annually (around April) based on the prior year's compensation, with additional charges or refunds. National pension recalculates your standard monthly income every July. A raise or promotion usually isn't reflected right away — it catches up at the next reconciliation point.
