The monthly National Health Insurance premiums borne by an employer and its employees are calculated by multiplying each employee’s monthly salary Income (excluding non-taxable income) by the insurance premium rate.   Long-term Care Security for the Elderly Insurance premium is imposed together with the National Health Insurance premium, and the premium is calculated by multiplying national health insurance premium by the insurance premium rate (i.e., surcharge of the national health insurance premium).

Effective from January 1, 2018, the insurance premium rate of the national health insurance will be increased from 6.12% to 6.24% of monthly salary income.  Each employer and employee portion rise from 3.06% to 3.12%, respectively.   In addition, the insurance premium rate of the long-term care security for the elderly insurance will also be increased from 6.55% to 7.38% of the national health insurance premium.

For example:

With the monthly salary income (excluding non-taxable income) of KRW 5,000,000, the insurance premiums will increase as shown below.
