Overview

The Overtime Pay Calculator computes premium pay for extended, night, and holiday work under Korea's Labor Standards Act. It applies 50% premium for overtime, 50% for night work (10 PM–6 AM), and 50–100% for holiday work based on the ordinary hourly wage.

Formula

Overtime Pay = Ordinary Hourly Wage × 1.5 × Overtime Hours
Night Work Pay = Ordinary Hourly Wage × 0.5 × Night Hours (22:00–06:00)
Holiday Pay = Ordinary Hourly Wage × 1.5 × Holiday Hours (≤ 8 hrs)
           = Ordinary Hourly Wage × 2.0 × Holiday Hours (> 8 hrs)

• Ordinary Hourly Wage = Monthly Ordinary Wage ÷ 209 hours
• Night + Overtime overlap: Ordinary Hourly Wage × 2.0

How to Use

Background

Korea's overtime, night work, and holiday work premium system is based on Article 56 of the Labor Standards Act. Employers must pay at least a 50% premium on ordinary wages for overtime (beyond statutory hours), night work (10 PM–6 AM), and holiday work respectively. The 2018 working hour reform introduced the 52-hour workweek, making overtime management stricter. Workplaces with fewer than 5 employees are exempt from premium pay requirements, and certain positions such as managerial and supervisory roles may also be excluded.

Tips

• ✔Workplaces with fewer than 5 employees are exempt from overtime premium requirements.
• ✔Overtime is capped at 12 hours per week under the Labor Standards Act.
• ✔When night work and overtime overlap, a 100% premium applies (2× ordinary hourly wage).
