Key concepts
The four major social insurances calculator (Korea) sums employee and employer shares of National Pension, Health Insurance, long-term care insurance, and Employment Insurance on a monthly-pay basis. This screen multiplies monthly pay by the entered rates, and long-term care only multiplies the computed health premium by a ratio. Income tax and local income tax are not included, so numbers differ from net salary.
It is simple multiplication without National Pension standard-income caps/floors, Health Insurance payroll caps, industry add-ons for Employment Insurance, or Durunuri reductions. When notices are revised, edit the rate fields. Results are for reference and may differ from a payslip or agency notice.
Example
Monthly pay 3,000,000 KRW at the on-screen default rates: employee National Pension 142,500 KRW, Health Insurance 107,850 KRW, long-term care 14,171 KRW, Employment Insurance 27,000 KRW, total 291,521 KRW. Employer Employment Insurance differs at 34,500 KRW for an employer total of 299,021 KRW; combined 590,543 KRW. Changing only monthly pay scales proportionally at the same rates. For reference.
