About WonPlan

WonPlan (원플랜) is a small, independent site that makes free money calculators for South Korea.

The Korean site covers salaries, loans, savings, severance and unemployment benefits for people in Korea. The English section helps foreign workers, students and travelers understand Korean pay slips, pension refunds and tax refunds in their own currency.

Formulas follow official sources: the National Pension Service, National Health Insurance Service, the National Tax Service withholding table (Enforcement Decree of the Income Tax Act, Table 2) and the Ministry of Employment and Labor. Results are estimates for reference; your employer or the agency has the final figure.
