About 퇴직금 계산기 - 세후 실수령액

'Severance Pay Calculator - Net After-Tax Payout' is an app that calculates severance pay and retirement income tax.

By entering your start date, last day of work, and average monthly salary, we calculate your net after-tax payout by subtracting retirement income tax and local income tax from your statutory severance pay.

Retirement income tax is automatically calculated using the annual installment method, allowing you to verify your actual estimated payout amount rather than a rough estimate.
