What this tool does

The 4 Major Insurances Calculator applies Korea's confirmed 2026 rates to split a single monthly salary into employee and employer shares across all five mandatory programs: National Pension, Health Insurance, Long-Term Care, Employment Insurance, and Workers' Compensation. From January 2026 the National Pension rate rose from 9% to 9.5% (4.75% each side), and Health Insurance rose from 7.09% to 7.19% (3.595% each). It automatically checks the pension income cap (6.37 million KRW) and shows both your net take-home pay and the employer's true labor cost. The Workers' Comp rate varies by industry, so you can adjust it yourself.

Who uses this

Employees: quickly verify that this month's payslip deductions are correct
HR/payroll staff: simulate a new hire's true labor cost (salary + employer-side insurance) before setting compensation
Freelancer-to-employee transition: compare offers by net pay after the 4 insurance deductions
Small business owners: budget total labor cost before deciding staff salaries
Gauge the impact of the 2026 National Pension and Health Insurance rate hikes

How to use (3 steps)

1Enter your monthly salary (standard remuneration) in KRW. Use pre-tax base pay plus fixed allowances. Irregular items such as bonuses or annual-leave pay may differ from actual deductions depending on whether they are included.
2Check the Workers' Comp rate. The default is the all-industry average of 0.86%; for high-risk sectors such as construction or manufacturing, switch to the rate published by COMWEL (e.g. ~3.6% for construction) for accuracy.
3Click Calculate to see a per-insurance table of employee and employer shares, your net take-home pay (salary − total employee share), and the employer's total labor cost (salary + total employer share).

Formula based on 2026 rates

National Pension: standard income × 9.5% (employee 4.75% / employer 4.75%) - Income cap 6,590,000 KRW / floor 410,000 KRW (Jul 2026 – Jun 2027) - 2026.1 pension reform hike: 9% → 9.5% Health Insurance: salary × 7.19% (employee 3.595% / employer 3.595%) - 2026 hike: 7.09% (frozen 2024–2025) → 7.19% Long-Term Care: health premium (employee + employer) × 13.14%, split in half - 2026 hike: 12.95% → 13.14% Employment Insurance (unemployment): salary × 1.8% (employee 0.9% / employer 0.9%) Employment Insurance (job stability/skills): employer only, 0.25% for firms under 150 staff Workers' Comp: salary × industry rate (employer pays 100%) - Average 0.86%, ranging 0.6%–38% by industry (COMWEL) [Rounded down to the nearest 10 KRW — same as the agencies' actual billing]

Worked examples

Example 1: Employee earning 3M KRW/month (2026 rates)

National Pension (employee): 3,000,000 × 4.75% = 142,500 KRW Health (employee): 3,000,000 × 3.595% = 107,850 KRW Long-Term Care: (107,850×2) × 13.14% ÷ 2 ≈ 14,140 KRW Employment: 3,000,000 × 0.9% = 27,000 KRW → Total employee deduction ≈ 291,490 KRW / net pay ≈ 2,708,510 KRW → Employer adds ≈ 351,080 KRW / total labor cost ≈ 3,351,080 KRW

Example 2: 7M KRW/month — above the pension cap

The National Pension income cap of 6,590,000 KRW (from Jul 2026) applies. Instead of 7M × 4.75%, it is 6.59M × 4.75% = 313,025 KRW (313,020 after rounding down to 10 KRW). Health Insurance, however, applies to the full 7M salary (3.595% = 251,650 KRW). A cap warning is shown automatically.

Example 3: Small employer — annual cost for a 36M KRW salary

At 3M/month the employer share is ~351,080 KRW × 12 = ~4,212,960 KRW per year. True annual labor cost = 36M + ~4.21M = ~40.21M KRW. The 2026 pension and health hikes raised this versus the prior year.

Frequently asked questions

Why was more National Pension deducted in 2026?

A 2025 amendment to the National Pension Act raised the rate from 9% to 9.5% (a 0.5 point increase) effective January 2026. It then rises 0.5 points each year to 13% by 2033. At a 3M KRW salary the employee's annual share rises by about 18,000 KRW.

How is the Long-Term Care premium calculated?

It is the health premium (employee + employer combined) multiplied by 13.14%, then split in half. In practice, the Long-Term Care line on your payslip ≈ your health premium (employee share) × 13.14%. It rose from 12.95% to 13.14% in 2026.

When does the National Pension income cap change?

The National Pension Service adjusts it every July based on the change in the average insured income. The current cap is 6,590,000 KRW for July 2026 – June 2027 (up from 6,370,000) and is reset again in July 2027. High earners above the cap pay a fixed maximum premium.

Does the job-stability/skills contribution vary by company size?

Yes. It is 0.25% for firms under 150 staff, 0.45% for priority-support firms of 150–under 1,000, 0.65% for other 150–1,000 firms, and 0.85% for firms of 1,000+ and government bodies. This tool defaults to 0.25% (under 150 staff).

What industry does the 0.86% Workers' Comp average represent?

It is the all-industry average published yearly by COMWEL. Actual rates differ widely — roughly 0.6% for finance/insurance, 1.0–2.0% for manufacturing, and ~3.6% for construction. Change it to your own industry rate for accuracy.

Can 3.3%-withholding freelancers use this calculator?

No — freelancers under 3.3% withholding (business-income earners) are not mandatorily enrolled in the four insurances, so this tool does not fit. Only 3% income tax + 0.3% local tax is withheld; the four insurances may instead require separate enrollment as a regional subscriber.

Cautions

•This tool uses confirmed 2026 rates; the National Pension income cap is 6.59M KRW (Jul 2026 – Jun 2027, adjusted every July).
•Amounts are rounded down to the nearest 10 KRW, so they may differ from agency bills by under 1 KRW.
•Whether irregular pay (bonuses, leave pay) counts toward the insurances depends on the employment contract and work rules; this tool treats the full input as standard remuneration.
•The Employment Insurance job-stability/skills rate varies by firm size. The default (0.25%) assumes under 150 staff.
•Results are for reference only. Confirm exact deductions via your payslip or the 4-Insurance EDI / your workplace administrator.
