What is Take-Home Pay Calculator?
This calculator uses the official monthly withholding table for taxable pay from KRW 770,000 to below KRW 10,000,000. Family count and eligible children aged 8–20 affect withholding. Social-insurance amounts are integer estimates under the reviewed 2026 policies, and actual payroll can differ after reconciliation.
How to Use
- Enter monthly gross pay and monthly non-taxable allowances.
- Enter reported NPS income, eligible family count, and children aged 8–20.
- Choose a 2026 date and the 80%, 100%, or 120% withholding rate.
- Review official-table tax and estimated social-insurance deductions.
Tips & Best Practices
- Subtract monthly non-taxable allowances from gross pay before the official-table lookup.
- Enter the official eligible-family count including yourself; counts above 11 use the published extension formula.
- Use only eligible children aged 8–20 for the separate monthly child credit.
- Choose the actual 2026 reference date because National Pension bounds change on July 1.
- Compare the estimate with your payslip after workplace reconciliation and institution rounding.

FAQ
What is the official withholding table range?
Monthly taxable pay must be at least KRW 770,000 and below KRW 10,000,000. Outside that published range, the calculator shows an error.
How do family count and children aged 8–20 affect tax?
Family count selects the official table column. The monthly child credit uses eligible children aged 8–20.
What do the 80%, 100%, and 120% choices do?
The percentage applies after child credit, and the result is floored to the nearest KRW 10.
Why can my payslip differ from this estimate?
Reported remuneration, workplace reconciliation, year-end settlement, and rounding can change actual deductions.
