1. Forms of disability benefit according to disability grade





- For Grades 4 ~ 7, select the form of disability benefit by submitting a “Confirmation Letter on Selection of Lump-sum Disability Compensation · Disability Compensation Annuity” to the Korea Workers’ Compensation and Welfare Service.

2. Calculation of lump-sum disability compensation annuity
- Lump-sum disability compensation annuity is calculated as follows:
Lump-sum disability compensation annuity = disability grade x average daily wage
- Persons eligible for lump-sum disability compensation: persons with Grade 4 ~ 7 disabilities who choose a lump-sum payment, or those with Grade 8 ~ 14 disabilities.
- Average daily wage in 2022: KRW 73,280 (minimum) ~ KRW 232,664 (maximum)
- Base date for lump-sum payment: lump-sum payment is calculated according to the following criteria and grade of disability



3. Calculating disability compensation annuity
- Disability compensation annuity is calculated as follows:
Monthly disability compensation = disability grade-based days x average daily wage / 12 months
- Persons eligible for disability compensation annuity: Grade 1 ~ 3 or those with Grade 4 ~ 7 disabilities who choose annuity
- Average daily wage in 2022: KRW 73,280 (minimum) ~ KRW 232,664 (maximum)
- Base date for annuity: Annuity payment is calculated according to the following criteria and grade of disability.
