How to use this tool
Enter gross monthly pay, tax-free meal allowance and monthly income tax in KRW. The model applies pension 4.75%, health 3.595%, employment 0.9% and long-term care at 13.14% of health.
Results and examples
Monthly net subtracts the insurance arithmetic and 110% of entered income tax from gross pay. Annualised net simply multiplies by 12 and does not include bonuses or year-end settlement.
Worked example
KRW 3 million gross, KRW 200,000 meal allowance and KRW 50,000 income tax gives approximately KRW 2,672,913 under the embedded rates.
Limitations
- Insurance earnings limits, exemptions and current rate applicability need review.
- Local income tax is assumed at 10% of entered income tax; other deductions are absent.

Frequently asked questions
Does it calculate income tax?
No. Enter the monthly amount you have checked.
Is the meal allowance deducted twice?
No. It reduces the insurance base, not gross cash pay again.
