Korea Overtime Pay Calculator for Foreign Workers

What this estimate includes

For a generally covered workplace with at least five regular employees, Korea's Labor Standards Act requires at least a 50% premium for statutory overtime. This tool estimates total pay for the entered overtime hours as ordinary hourly wage multiplied by hours multiplied by 150%. It keeps base pay and the additional premium separate for clarity.

How the calculation works

1. When hourly ordinary wage is selected, the entered whole-won amount is used directly. When monthly ordinary wage is selected, it is divided by the monthly ordinary-wage calculation hours entered by the user.
2. Base pay for the entered overtime hours is ordinary hourly wage multiplied by the entered hours.
3. For a workplace selected as five or more regular employees, total overtime pay is ordinary hourly wage multiplied by overtime hours multiplied by 150%. The additional premium is the difference between that total and base pay.
4. For a workplace selected as four or fewer employees, the tool calculates base pay for the entered hours without adding the statutory Article 56 premium, which generally does not apply. If workplace size is unknown, it applies the covered-workplace formula and clearly marks that assumption for confirmation.
5. All calculations use integer ratios and hundredths of an hour before the final whole-won amount is rounded down.

Assumptions

• The entered hours are statutory overtime, generally hours actually worked beyond 8 hours in a day or 40 hours in a week, excluding break time.
• The ordinary wage input is the legally relevant ordinary wage, not take-home pay or automatically the entire gross salary.
• The calculation covers extended work only. It does not add night-work or holiday-work premiums, even when the same hour could overlap.
• The workplace-size choice refers to the regular employee count used for Labor Standards Act coverage, not simply the number present during one shift.

Example

If ordinary hourly wage is KRW 12,000 and a worker enters 10 statutory overtime hours at a workplace with at least five regular employees, base pay for those hours is KRW 120,000, the 50% overtime premium is KRW 60,000, and the total overtime-pay estimate is KRW 180,000.

Limits and cautions

• The tool does not decide whether particular attendance records legally qualify as overtime or whether waiting, preparation, travel, or on-call time counts as working time.
• Part-time employees can have separate rules for work beyond contractual hours even before the general 8-hour or 40-hour limit; obtain an official review when that applies.
• Flexible, selective, or elastic work schedules, special industries, minors, compensatory leave, inclusive-wage agreements, and managerial or supervisory disputes are outside this simple formula.
• A contract or collective agreement can provide more than the statutory minimum, including at a workplace with fewer than five employees.
• Night and holiday premiums can overlap with overtime in some situations. Use the separate night and holiday tool rather than silently adding them here.
