How Your Take-Home Pay Is Calculated
① The first line — what makes up the 3,000,000 KRW gross pay
This example is a new hire earning 3,000,000 KRW gross per month (36M KRW/yr). The top of the payslip separates base pay from a tax-free meal allowance of 200,000 KRW. Both insurance premiums and income tax are calculated on taxable pay of 2,800,000 KRW — gross pay minus the meal allowance — so this figure is the starting point for every deduction below. See also the four-insurances guide.
② National Pension 4.75% — why 133,000 KRW is withheld
| Item | Amount |
|---|---|
| Base monthly income | 2,800,000 원 |
| Rate | 4.75% |
| Employee pension premium | 133,000 원 |
The pension premium is 4.75% of the base monthly income: 2,800,000 × 4.75% ≈ 133,000 KRW. That base is capped between a floor of 410,000 and a ceiling of 6,590,000 KRW — outside that range the floor/ceiling applies instead of actual pay. This case falls between the two, so actual taxable pay was used as-is.
③ Health insurance 3.595% + long-term care — the next two lines
| Item | Amount |
|---|---|
| Health (3.595%) | 100,660 원 |
| Long-term care (13.14% of health premium) | 13,227 원 |
Health insurance is 3.595% of taxable pay (2,800,000) ≈ 100,660 KRW. Long-term care isn’t a separate percentage of pay — it’s 13.14% of the health premium itself: 100,660 × 13.14% ≈ 13,227 KRW, shown as its own line. See the 2026 rate table for the current figures.
④ Employment insurance 0.9% — funding unemployment benefits
Employment insurance (the unemployment-benefit portion) takes 0.9% of taxable pay: 2,800,000 × 0.9% ≈ 25,200 KRW. This employee’s total four-insurance deduction is pension 133,000 + health 100,660 + long-term care 13,227 + employment 25,200 = 272,087 KRW. The employer matches all four at the same rates, and pays accident insurance in full on top.
⑤ Income tax & local tax — why only 65,545 KRW
Income tax doesn’t apply directly to taxable pay. It first subtracts the labor income deduction (a bracket-based automatic deduction) and the basic personal deduction (1,500,000 KRW/yr for the employee alone — no dependents in this case), plus the pension/health/care/employment premiums already paid, to reach a tax base taxed at progressive rates of 6–45%. Dividing the resulting annual tax by 12 gives a monthly income tax of 65,545 KRW, and local income tax is 10% of that: 6,555 KRW.
In practice, many employers withhold a slightly different amount each month using the NTS simplified withholding table, and the gap is settled at year-end. This figure is an annualized estimate — check the rate table or NTS Hometax for exact amounts.
⑥ The bottom line — final take-home pay
| Item | Monthly amount |
|---|---|
| Pension (4.75%) | 133,000 원 |
| Health (3.595%) | 100,660 원 |
| Long-term care | 13,227 원 |
| Employment (0.9%) | 25,200 원 |
| Income tax | 65,545 원 |
| Local income tax | 6,555 원 |
| Total deductions | 344,187 원 |
| Take-home pay | 2,655,813 원 |
Subtracting total deductions (344,187) from gross pay (3,000,000) leaves take-home pay of 2,655,813 KRW, about 31,869,756 KRW a year. Try the net salary calculator with your own numbers.
