The cost of hiring an employee in Korea is higher than the employee’s stated gross salary. Employers must also budget for social insurance contributions, statutory severance and other payroll-related costs.
2026 Employer Social Insurance, Severance and Total Employment Cost Guide
When a foreign company plans to hire an employee in Korea, the number shown in the offer letter is only the starting point.
In addition to gross salary, a Korean employer generally bears its share of National Pension, National Health Insurance, Long-Term Care Insurance, Employment Insurance and Workers’ Compensation Insurance. The employer should also budget for statutory severance or retirement benefit costs from the beginning of employment.
As a practical starting point, the basic annual employer cost may be approximately 20% above annual gross salary once employer social insurance and a preliminary severance reserve are included. Overtime, unused annual leave payments, bonuses, benefits, recruitment, immigration and payroll administration may increase the cost further.
Quick example: For an employee with an annual gross salary of KRW 50 million, the preliminary annual employer cost may be approximately KRW 59.9 million, before variable compensation and other company-specific costs.
Gross Salary Is Not the Employer’s Total Cost
Annual gross salary is the compensation promised to the employee before employee deductions. It does not normally include the employer’s own statutory contributions.
For headcount budgeting, an employer should consider at least the following:
- annual gross salary and wage-type bonuses;
- the employer portion of National Pension;
- the employer portion of National Health Insurance;
- the employer portion of Long-Term Care Insurance;
- the employer portion of Employment Insurance;
- Workers’ Compensation Insurance, which is fully borne by the employer;
- statutory severance or retirement pension contributions;
- overtime, nighttime and holiday work premiums;
- unused annual leave payments where applicable;
- benefits, recruitment and immigration costs; and
- payroll, tax filing, social insurance and payment administration.
This is why multiplying the contractual salary by the number of employees does not produce a complete Korean headcount budget.
2026 Employer Social Insurance Rates in Korea
The following rates provide a general 2026 budgeting framework for an ordinary employee.
| Program | General 2026 employer rate | Important qualification |
|---|---|---|
| National Pension | 4.75% | Applied to the standard monthly income, subject to a floor and ceiling. Foreign employees may be exempt depending on nationality or a social security agreement. |
| National Health Insurance | 3.595% | One-half of the total employee insurance rate of 7.19%. Contribution bases and ceilings apply. |
| Long-Term Care Insurance | Approximately 0.4724% | Employer’s wage-equivalent share based on the 2026 total wage-equivalent rate of 0.9448%. |
| Employment Insurance | 1.15%–1.75% | Includes the employer’s 0.9% unemployment-benefit contribution plus 0.25%–0.85% for employment stabilization and vocational development, depending on company size and status. |
| Workers’ Compensation Insurance | Industry-specific | Fully borne by the employer. The 2026 national average rate is approximately 1.47%, but the assigned rate varies by business classification and risk. |
Using the 2026 national average Workers’ Compensation Insurance rate, an ordinary employer may preliminarily estimate its social insurance burden at approximately 11.44% to 12.04% of applicable remuneration.
This percentage is not a universal rate. The actual calculation may differ because each insurance program has its own contribution base, ceiling, eligibility rules and reconciliation procedures.
National Pension ceiling from July 2026
For the period from July 1, 2026 through June 30, 2027, the National Pension standard monthly income ranges from KRW 410,000 to KRW 6,590,000. Income reported above the ceiling is generally limited to the ceiling for contribution purposes.
The calculator below uses the July 2026 ceiling for a preliminary current-rate estimate. A final 2026 calendar-year calculation may differ because the prior ceiling applied during the first half of 2026.
Statutory Severance Should Be Budgeted from the Hiring Date
Korean statutory severance is not merely a discretionary termination payment.
An employee who generally completes at least one year of continuous service and works an average of at least 15 scheduled hours per week is entitled to a retirement benefit equivalent to at least 30 days of average wages for each year of continuous service.
The final severance amount does not always equal exactly one month of base salary. It may be affected by:
- the employee’s average wages before retirement;
- bonuses and allowances included in the statutory calculation;
- unused annual leave payments;
- wage changes during employment;
- periods excluded from the average-wage calculation;
- total continuous service; and
- the company’s DB, DC or statutory severance arrangement.
For annual budgeting only, one-twelfth of annual remuneration, or approximately 8.33%, is a useful preliminary reserve. It is not a substitute for the final statutory calculation.
For a detailed explanation and a separate severance calculator, see Korea Severance Pay: Calculation, Retirement Pensions and IRP Payment Rules.
Example: Employee with a KRW 50 Million Annual Salary
Assume the following:
- annual gross salary: KRW 50,000,000;
- the full amount is treated as applicable remuneration for this estimate;
- the employee is covered by National Pension and earns below the applicable ceiling;
- the employer uses the 1.15% Employment Insurance rate applicable to an ordinary employer with fewer than 150 employees;
- Workers’ Compensation Insurance is estimated using the 2026 national average rate of 1.47%;
- the severance reserve is estimated at one-twelfth of annual salary; and
- bonuses, overtime, benefits and payroll administration costs are excluded.
| Cost item | Preliminary annual amount |
| Annual gross salary | KRW 50,000,000 |
| Employer National Pension — 4.75% | KRW 2,375,000 |
| Employer National Health Insurance — 3.595% | KRW 1,797,500 |
| Employer Long-Term Care Insurance — approximately 0.4724% | KRW 236,200 |
| Employer Employment Insurance — 1.15% | KRW 575,000 |
| Workers’ Compensation Insurance — 1.47% assumed | KRW 735,000 |
| Preliminary severance reserve — approximately 8.33% | KRW 4,166,667 |
| Estimated annual employer cost | KRW 59,885,367 |
Under this simplified example, the employer’s basic annual cost is approximately 19.8% higher than the contractual salary.
Korea Employer Cost Calculator
Use the calculator for a preliminary annual budget based on the general 2026 employer rates described above.
Important: The calculator estimates employer costs before payroll service fees and other company-specific expenses. It does not determine an employee’s net pay, income tax or employee social insurance deductions.
KOREA PAYROLL TOOL Estimate the employer’s basic annual cost using general 2026 Korean social insurance rates and an optional preliminary severance reserve. ESTIMATED ANNUAL EMPLOYER COST This tool does not calculate employee deductions, net pay, employment income tax, benefits, overtime, leave payments, payroll fees or a final retirement benefit. It uses general percentage assumptions and does not apply every insurance ceiling or reconciliation rule. High compensation, expatriate arrangements and special wage items require an individual review. Calculation takes place only in your browser.

Estimated annual breakdown
The calculator allows the user to:
- enter annual gross salary and additional wage payments;
- change the employer’s Employment Insurance rate;
- enter the company’s assigned Workers’ Compensation Insurance rate;
- turn National Pension on or off for a preliminary exemption scenario; and
- include or exclude a preliminary severance reserve.
It applies the July 2026 National Pension income ceiling for estimation purposes. Actual premiums should be calculated using the employee’s registered contribution bases and the company’s assigned rates.
Foreign Employees May Produce a Different Result
The social insurance cost of a foreign employee should not automatically be assumed to match that of a Korean employee.
National Pension coverage may depend on the employee’s nationality, reciprocity rules and an applicable social security agreement. A home-country assignee may also have a different result from a foreign national hired directly by the Korean entity.
Other issues may include:
- National Pension exemption documentation;
- Employment Insurance coverage by visa type or nationality;
- Korean National Health Insurance eligibility;
- compensation paid partly by an overseas headquarters;
- split payroll or shadow payroll;
- tax equalization or tax protection;
- housing, education and other benefits; and
- gross-up of a guaranteed net salary.
For an expatriate or globally mobile employee, payroll, individual income tax and social insurance should therefore be reviewed before the offer package is finalized.
Is Employee Income Tax an Additional Employer Cost?
Ordinary Korean employment income tax and local income tax are withheld from the employee’s gross salary. They are generally not an additional employer cost.
The employer is nevertheless responsible for calculating, withholding, reporting and paying the taxes, and for completing the employee’s Korean Year-End Tax Settlement.
Income tax may become a direct employer cost where the company guarantees a net salary or operates a tax equalization or tax protection policy. In that case, the compensation budget should be calculated on a grossed-up basis, and the total cost can be materially higher than the result shown by this calculator.
Costs Not Included in the Calculator
The estimator focuses on basic payroll-related employer costs. A complete employment budget may also need to include:
- recruitment agency fees;
- visa and immigration support;
- overtime, nighttime and holiday premiums;
- performance bonuses, commissions and equity compensation;
- meal, transportation, housing, private insurance and other benefits;
- unused annual leave payments and staffing coverage;
- retirement pension administration or additional funding;
- payroll processing, tax filing and payment administration fees;
- legal advice for employment documentation; and
- termination, labor dispute and settlement costs.
Some items may also increase the wage base used for statutory allowances and severance. Compensation design should therefore be reviewed as a connected payroll and employment-cost issue rather than as a collection of separate payments.
Practical Budgeting Formula
For a preliminary ordinary-employee budget, the following formula is a useful starting point:
Annual gross remuneration + approximately 11.44%–12.04% employer social insurance + approximately 8.33% preliminary severance reserve
In other words, an employer may begin with a budget of approximately 120% of annual gross remuneration, before adding variable compensation, benefits, payroll administration and other company-specific costs.
This guideline is deliberately conservative and simplified. A company-specific estimate should be prepared before the employment terms are finalized.
Review the Cost Before Making the Offer
The cost of hiring one employee in Korea cannot be determined from the offer-letter salary alone. Social insurance eligibility, contribution ceilings, company size, industry classification, nationality, compensation structure and retirement benefit arrangements can all change the result.
Our payroll team can prepare a tailored employer-cost projection based on the proposed compensation package, employee profile and Korean entity details.
