Formula and scope
Employee rates: pension 4.75%, health 3.595%, care = health premium × 0.9448 ÷ 7.19, employment 0.9%. Pension income is truncated to KRW 1,000 and bounded at 400,000–6,370,000 in January–June or 410,000–6,590,000 in July–December. Health employee premium limits are KRW 10,080–4,591,740 monthly. Estimates truncate each premium to KRW 10.
What this calculator cannot apply
Assumes an ordinary employee enrolled in all schemes. Industrial accident insurance has no employee charge; employer charges are excluded. Non-wage income, multiple jobs, age/enrolment exemptions, leave, settlement and reductions are excluded. Zero remuneration means a zero-payment scenario, not an approved exemption. Billing and rounding may differ.
