How to use this tool
Enter the KRW net target, hourly wage and daily hours, then choose no deductions, 3.3% or insurance. Insurance mode uses only the embedded contribution total and excludes income tax.
Results and examples
Gross target is net divided by one minus the rate; hours divide gross by wage and days divide by daily hours. The 3.3% option is a withholding scenario, not a final tax liability.
Worked example
KRW 96,700 net at 3.3%, KRW 10,000 hourly and five hours daily gives KRW 100,000 gross, ten hours and two days.
Limitations
- Paid-rest, overtime, minimum-wage eligibility and tax settlement are excluded.
- Current insurance rates and enrolment applicability still need review.
