2026 Workplace Health Insurance Premium Calculation: The Complete Guide

Workplace health insurance premiums are one of the significant fixed expenses for many employees. Since the National Health Insurance is levied in proportion to the worker's income, many are curious about the amount deducted from their monthly salary. Let's explore what changes to expect in 2026 and how to calculate it.

2026 Workplace Health Insurance Premium Rate

The 2026 workplace health insurance premium rate has been frozen at 7.09%. This is the same as the previous year, as the government is suppressing rate increases to ease the burden on workers before reaching the legal upper limit of 8.0%. This rate is structured so that the employee and employer each bear 50% of the cost. In other words, employees pay 3.545% of their monthly salary income as health insurance premiums.

Relationship with Long-Term Care Insurance Premiums

The Long-Term Care Insurance premium, deducted monthly along with the workplace health insurance premium, cannot be ignored. This premium is based on 12.95% of the health insurance premium, and the principle of equal contribution between the employee and the company applies. That is, after the health insurance premium is calculated, the long-term care insurance premium is determined by multiplying that amount by 12.95%.

Calculating Your Actual Health Insurance Premium

So, how can you actually calculate your health insurance premium? Let's take the example of Employee A, whose monthly salary income is 4 million won.

• Monthly Salary Income: 4 million won
• Total Health Insurance Premium: 4 million won × 7.09% = 283,600 won
• Employee's Share of Health Insurance Premium: 283,600 won × 0.5 = 141,800 won
• Long-Term Care Insurance Premium: 141,800 won × 12.95% = 18,360 won
• Total Deduction: 141,800 won + 18,360 won = 160,160 won

Ultimately, Employee A will have a total of 160,160 won deducted from their salary each month for health insurance-related costs.

Important Notes on Income-Based Monthly Premiums

Additionally, employees who earn additional income should pay attention to the income-based monthly premium. If your annual income exceeds 20 million won, additional premiums may be levied. In this case, the 7.09% rate applies only to the excess amount, and the employee bears the full cost.

Conclusion

The 2026 workplace health insurance premium reflects a fair taxation structure. A 7.09% rate is shared for the basic salary, with additional long-term care insurance premiums incurred. Especially if you have additional income from side jobs or investments, you must include the income-based monthly premium in your calculations. It is also important to verify that your monthly health insurance deductions are being calculated correctly.
