SEVERANCE PAY
Estimate Korean severance pay,
with the working shown.
From your start date, last working day and the last three months of wages, it estimates gross severance under Korea’s general formula. The period, day counts and whether the average or ordinary wage was used are kept as evidence. For reference only.

In short Severance calculator is a free web tool that estimates Korean severance pay before tax using the general formula (average daily wage × 30 × days of service ÷ 365) and shows the calculation basis. It runs in your browser with no install or sign-up, and what you type stays on your device — nothing is sent to a server. A pre-tax reference estimate using Korea’s general formula; it doesn’t assess taxes or legal entitlement. Amounts are whole won from 0 to 10 billion; the last working day must fall between 1900 and 2100.

GOOD TO KNOW
Good to know
- Gross reference estimate only. It does not decide legal entitlement, employee status, wage classification, tax or DC balances. Defined-contribution (DC) plans are not supported.
- Cases outside the general formula are not calculated. Interim settlements, historical small-business rules, bonus schemes changed mid-year or unclear wages lead to a note that official advice and extra records are needed. With less than one year of service, no amount is confirmed.
- Formula: (wages after exclusions + bonus ÷ 4 + leave pay ÷ 4) ÷ days gives the average daily wage, compared with a higher verified ordinary wage; daily basis × 30 × service days ÷ 365. Only the final won amount is rounded.
- As of 2026-10-06: based on official guidance checked on that date. If the rules change, recheck the Ministry of Employment and Labor (MOEL) calculator and guidance.
- The input JSON contains all your wage data. Check it before sharing. Inputs are not saved automatically.
