Overview

The Hourly Wage Calculator converts monthly or annual salary into an hourly rate, or calculates monthly/annual pay from an hourly wage. It uses Korea's statutory working hours (40 hours/week, 209 hours/month including paid weekly holiday) for accurate conversion.

Formula

Hourly Wage = Monthly Salary ÷ Monthly Contractual Hours

• Monthly Contractual Hours = (Weekly hours + Paid weekly holiday hours) × (365 ÷ 7) ÷ 12
• Standard 40-hour week: 209 hours/month (including 8 hours paid holiday)
• From annual salary: Hourly Wage = Annual Salary ÷ 12 ÷ 209

How to Use

1. 1Enter your monthly salary (or annual salary) or hourly wage.
2. 2Set your weekly working hours (default: 40 hours).
3. 3Choose whether to include paid weekly holiday allowance.
4. 4Click 'Calculate' to see hourly, daily, monthly, and annual figures.

Background

Korea's working hour system is governed by the Labor Standards Act. Since the 2018 introduction of the 52-hour workweek, the legal maximum is 40 regular hours plus 12 overtime hours per week. The standard 209 monthly hours is calculated as (40 weekly hours + 8 paid holiday hours) × 365 ÷ 7 ÷ 12. The paid weekly holiday allowance is mandatory for employees working 15+ hours per week with perfect attendance. This inclusive hourly rate calculation serves as the basis for minimum wage compliance checks. The 2025 minimum hourly wage is KRW 10,030.

Tips

• ✔Working 15+ hours per week entitles you to a paid weekly holiday, which affects hourly rate conversion.
• ✔209 hours represents the monthly standard for a 40-hour workweek plus 8 hours of paid weekly holiday.
• ✔If your hourly wage falls below the minimum wage (KRW 10,030 in 2025), it violates labor law.
