FAQ

How is severance calculated?

Formula under Korean law: severance = average daily wage × 30 × (service days / 365). Average daily wage = (last-3-months wages + annual bonus × 3/12 + last-year unused leave pay × 3/12) / 3-months days.

Is there severance for under 1 year of service?

No statutory obligation. The Employee Retirement Benefit Security Act requires at least 1 year of continuous service for severance entitlement. Some employers pay voluntarily but are not legally required to. The tool warns when service is under 1 year.

Average wage vs. ordinary wage?

Korean law requires using the larger of average wage and ordinary wage. This tool uses average wage; if ordinary wage is higher, actual severance can exceed this result. Consult a labor attorney or the Ministry of Employment & Labor for an exact comparison.

Why multiply bonus and leave pay by 3/12?

Average wage covers the 'last 3 months', so we add only the 3-month portion of yearly bonus and leave pay: annual amount × (3/12) = 3 months' worth.

Will my actual payout differ?

It may. This tool returns a pre-tax estimate. Take-home is reduced by retirement income tax (separately assessed with service-year deductions) and local tax. Employers using ordinary wage or custom severance rules (progressive multipliers, etc.) may pay differently.

Is my input sent to a server?

No. All computation runs in your browser. Inputs are never sent over the network, never stored in localStorage or cookies. Closing the tab clears everything from memory.
