What are the 4대보험 (four major insurances)?

They are national pension (국민연금), national health insurance (건강보험), employment insurance (고용보험), and long-term care insurance (장기요양보험), plus worker's compensation paid entirely by the employer. The first four are split between employee and employer.

What are the 2024 rates?

National pension is 9 percent (4.5 percent each), health insurance is 7.09 percent (3.545 percent each), long-term care is 12.95 percent of the health premium, and employment insurance is 1.8 percent split equally plus an employer-only job-stability portion.

Is national pension capped?

Yes. National pension applies to a monthly standard income between a floor and ceiling (about 390,000 to 6,170,000 KRW for 2024). Income above the ceiling is not subject to additional pension contributions.

Who pays worker's compensation insurance?

Worker's compensation (산재보험) is paid entirely by the employer at a rate that varies by industry, typically under 1 percent. It is not deducted from the employee, so it is shown separately from your take-home calculation.

Is long-term care a separate percentage of salary?

No. Long-term care insurance is charged as a percentage (12.95 percent for 2024) of your health insurance premium, not of your salary directly. The tool applies it to the computed health premium.

South Korea 4대보험 Calculator

South Korea’s four major insurances (4대보험) are mandatory social-insurance deductions taken from monthly salary. National pension, health insurance, long-term care, and employment insurance are split between employee and employer. This calculator applies the 2024 rates and shows both shares.

How it works

Each premium is a percentage of monthly salary (long-term care is a percentage of the health premium):

national pension = capped salary × 9% (4.5% employee / 4.5% employer)
health insurance = salary × 7.09% (3.545% each)
long-term care = health insurance × 12.95% (split equally)
employment insurance = salary × 1.8% (0.9% employee / 0.9% employer base)

National pension uses a standard-income floor and ceiling, so very high or very low salaries are bounded. Worker’s compensation is employer-only and varies by industry, so it is not part of the employee deduction.

Example

For a monthly salary of 3,000,000 KRW: pension is 270,000 (135,000 each), health is 212,700 (106,350 each), long-term care is about 27,544 (13,772 each), and employment is 54,000 (27,000 each). The employee’s total deduction is roughly 282,122 KRW.

Notes

Rates change yearly; the defaults reflect 2024. The pension ceiling bounds high earners. Confirm exact figures with the National Health Insurance Service (NHIS) and National Pension Service (NPS).
