First Paycheck: KRW 2.6M Gross, KRW 2.31M in Hand

A new employee receives their first paycheck of KRW 2.6 million, but only KRW 2.31 million arrives in their bank account. This scenario walks through how Korea's four social insurances (National Pension, Health Insurance, Long-term Care, Employment Insurance) and income tax withholding reduce gross pay to take-home pay. It then explores weekly holiday pay (juhyu-sudang) for part-time context, and how a savings deposit with compound interest can grow the monthly surplus.
