Korean 4-Insurance Calculator
Calculate Korean 4-insurance deductions with 2026 rates. Split worker/employer shares with a freelancer 3.3% side-by-side.
About this tool
Korean 4-Insurance Calculator computes monthly deductions for National Pension (2026 9.5%), Health Insurance (7.09%), Long-term Care (12.95% × health), Employment, and Workers’ Comp using the 2026 statutory rates. It splits employee vs. employer burden, applies the National Pension floor (₩400k) and ceiling (₩6.37M), excludes National Pension for ages 60+, and handles industry-specific Workers’ Comp rates (0.7–37.5%). Income tax is estimated at the 8% wage-class default to reach net take-home, with a 2025↔2026 toggle and a freelancer-3.3% side-by-side. Result PNG downloadable; all math runs in the browser.
Use cases
Scenario 1
Monthly ₩3.5M white-collar take-home

For employees age 60+, see National Pension auto-excluded and the resulting take-home with health-only deduction.

Frequently asked
- Q. What is the 2026 National Pension rate?
- A. 9.5% total (employee 4.75% + employer 4.75%), up 0.5pp from 2025’s 9.0%. The tool defaults to 2026 with a toggle back to 2025.
- Q. Is the basis gross salary?
- A. Yes — the gross monthly salary (보수월액). National Pension also applies a ceiling of ₩6.37M and a floor of ₩400k.
- Q. What happens to NPS at age 60?
- A. Mandatory NPS coverage ends at age 60 — only voluntary continuation applies after that. The tool auto-excludes NPS for ages 60+.
- Q. Who pays Workers’ Comp?
- A. Employer pays 100% — never deducted from the worker. Industry rates range from 0.7% to 37.5%; the tool surfaces the employer line separately.
- Q. How exact is the net take-home?
- A. The 4-insurance side is exact, but income/local tax depends on dependents and credits — the tool uses the 8% wage-class default. Verify with the NTS withholding table or your payslip.
