Korea Salary Net Pay Calculator
Estimate Korean monthly and annual take-home pay after the four major insurances (national pension, health, long-term care, employment) and income/local taxes. Supports dependents, children, and the non-taxable meal allowance.
Salary Information
Total family members eligible for the personal deduction, including yourself.
Up to 200,000 KRW per month for meals is recognised as non-taxable.
Formula and decision logic
Korean salary net pay subtracts the four major insurances (national pension, health, long-term care, employment) plus income tax and local tax from monthly gross pay, based on annual salary, dependents and non-taxable allowances.
Monthly net = monthly gross − (national pension + health + long-term care + employment + income tax + local tax)
Income tax base = work income − personal deduction − insurance − standard deduction
Worked examples
Married with 2 children, 70M annual
Input: Annual 70,000,000, dependents 4, children 2, meal 200,000
Result: Higher personal and child tax credits reduce income tax
How to use this calculator
- 1Enter your gross annual salary in KRW
- 2Set the number of dependents and children aged 8–20
- 3Enter the monthly non-taxable amount and press Calculate
- 4Review monthly and annual net pay plus each deduction
How to read the result
- Net pay grows less than gross pay because progressive income tax and insurance scale with the base.
- Adding eligible dependents and children lowers the income tax portion meaningfully.
Common input mistakes
- Forgetting the monthly non-taxable meal allowance (up to 200,000 KRW).
- Treating annual gross salary as take-home without applying insurance and tax deductions.
Frequently asked questions
How is the net salary calculated?
From the monthly gross (annual / 12) we subtract the four major insurances (national pension 4.5%, health 3.545%, long-term care 12.95% of health, employment 0.9%) plus income tax and local tax (10% of income tax).
How does the non-taxable allowance work?
The monthly non-taxable amount (e.g., meal allowance up to 200,000 KRW) is excluded from the base used for both insurances and income tax, increasing your net pay.
Do dependents and children change the result?
Yes. Each dependent reduces taxable income by 1.5M KRW, and child tax credits (150k for 1, 350k for 2, +300k from the third) reduce the income tax further.
Why does the result differ from my actual payslip?
Korean employers withhold tax monthly using a simplified table and reconcile at year-end. This calculator uses the annual income-tax method, so monthly amounts are an approximation.
