How It's Calculated
Your gross annual salary is divided by 12 to get the monthly gross pay. From this, the following deductions are applied:
• National Pension: 4.5% of monthly gross (capped at a maximum standard income) • Health Insurance: 3.545% of monthly gross • Long-term Care Insurance: 12.81% of the Health Insurance amount • Employment Insurance: 0.9% of monthly gross • Income Tax: calculated using Korea's progressive tax brackets (6%–45%) with the simplified withholding table • Local Income Tax: 10% of income tax
Net take-home pay = Monthly Gross − (4 insurances + Income Tax + Local Income Tax). The calculator also shows total annual deductions and your effective tax rate.
⚠️ Disclaimer
This calculator provides estimates based on standard Korean social insurance rates and simplified tax withholding tables.
