Korea Overtime Pay Calculator
Estimate South Korea pre-tax weekday overtime pay from hourly wage and work time.
This uses the general Labor Standards Act Article 56 assumption of a 50% weekday overtime premium. Actual applicability can vary by recognized work hours, rest breaks, employment contract, comprehensive wage arrangements, workplace size, and attendance records.
Overtime Pay Estimate
Target-Hour Gross Pay
77,400 KRW
Base pay plus overtime premium for the hours calculated as overtime, not the full shift.
Total Premium Pay
25,800 KRW
Only the overtime premium addition. Night and holiday premiums are excluded.
Target-Hour Base Pay
51,600 KRW
The 100% base portion for hours calculated as overtime, not the full shift.
General weekday overtime premium is +50% of ordinary hourly wage. This individual calculator only estimates overtime pay, so night and holiday premiums are excluded. Use the Additional Pay Calculator to combine the full work time and overlapping premiums.
Overtime, Night, and Holiday Pay Assumptions
Reference date and last reviewed: July 10, 2026
Calculation Basis
Derives worked time from clock-in, clock-out, and break inputs, separates time beyond eight hours per day, night work from 10 p.m. to 6 a.m., and selected holiday-work bands, then applies ordinary hourly wage and premium rates.
Reference Limits
The tool places break time in assumed periods and does not determine every rule for flexible schedules, shifts, inclusive-wage agreements, or differences by workforce size. The general 50% premium should be checked under rules applicable to workplaces with at least five regular workers.
When to Confirm Officially
If actual breaks, workforce size, schedule type, wage-inclusive terms, or unpaid premiums are disputed, review the contract, roster, attendance records, and payslips with a labor professional or the labor authority.
Usage Tips
Use this page when you want weekday overtime pay only
The calculator classifies hours beyond the daily 8-hour standard from clock-in/out time and breaks, then estimates overtime pay only. Night and holiday premiums are excluded, so use the Additional Pay Calculator for overlapping premium totals.
What is Korea Overtime Pay Calculator?
The Korea Overtime Pay Calculator estimates weekday overtime pay for hours beyond the daily standard from hourly wage, clock-in time, clock-out time, and break hours. It focuses on overtime pay only, showing target-hour base pay, overtime premium, total premium pay, and target-hour gross pay. Separate night and holiday premiums are excluded here, so use the Additional Pay Calculator when you need the full shift amount with overlapping premiums.
How to Use
- 1Enter the hourly wage. The default is KRW 10,320, the 2026 South Korea minimum hourly wage assumption used by this site.
- 2Enter clock-in time, clock-out time, and break hours. If clock-out is earlier than clock-in, it is treated as next-day clock-out.
- 3Review gross span, worked time after break, and overtime hours in the automatic classification area.
- 4Check target-hour base pay, overtime premium, total premium pay, and target-hour gross pay in the result cards.
- 5Remember that any 10 p.m.-6 a.m. overlap is still calculated as overtime only on this page.
- 6Open the Additional Pay Calculator if you need full-shift base pay plus overlapping night or holiday premiums.
- 7Review the automatically classified overtime hours.
- 8Copy the result into payroll review notes, attendance summaries, or labor consultation preparation notes.
Automatic weekday overtime classification
Last reviewed: July 10, 2026Base pay and premium beyond eight hours
overtime-target gross = hourly wage×overtime hours×(100% base + 50% premium)
The tool subtracts break time from the clock span and classifies paid time beyond eight hours in a day as overtime. This page excludes overlapping night and holiday premiums.
Example: KRW 10,320/hour, 09:00–20:00, one-hour break
- • 11-hour clock span
- • 1-hour break
- • 10 paid hours
- 1. overtime = 10−8 = 2 hours
- 2. target-hour base pay = 10,320×2 = KRW 20,640
- 3. overtime premium = 10,320×2×50% = KRW 10,320
- 4. target-hour gross = KRW 30,960
Pre-tax gross for the two overtime hours is KRW 30,960. It is not gross pay for the entire 10-hour shift.
How to read the result
- Base pay is the ordinary 100% portion for target hours; overtime premium is the additional 50% portion.
- The gross result card covers hours classified as overtime, not the whole workday.
- Even if work overlaps 10 p.m.–6 a.m., this individual page does not add a night premium.
Conditions that change the result
- The statutory 50% premium generally assumes a workplace with at least five regular employees; exemptions and special rules require confirmation.
- Flexible work systems, approved exempt work, comprehensive wage arrangements, employer approval, and attendance records can change recognized hours.
- Because break clock times are not entered, classification assumes the entered break was validly placed within the schedule.
Common input mistakes
- Do not treat the entire clock-in to clock-out span as paid work while leaving break time at zero.
- Do not read target-hour gross pay as total pay for the full shift.
- Use the Additional Pay Calculator for final review when overtime overlaps night or holiday work.
Reference Knowledge
- ●Article 56 of South Korea's Labor Standards Act is the general reference point for weekday overtime premium.
- ●Weekday overtime premium is generally hourly wage × overtime hours × 50%.
- ●Including base pay, the overtime target-hour gross rate is 150%: base 100% plus overtime premium 50%.
- ●This individual calculator excludes separate night premium and holiday premium.
- ●Overtime that also falls between 10 p.m. and 6 a.m. is still shown as overtime only here. Use the Additional Pay Calculator for the combined 200% structure.
- ●Break time is excluded from worked time, so different break records can change the calculated overtime hours.
- ●Overtime recognition can depend on employment contract, company approval, attendance records, comprehensive wage arrangements, workplace size, and approved exempt work categories.
- ●The total gross pay shown here is for hours classified as overtime, not the gross pay for the entire shift.
FAQ
Q.What rate is used for weekday overtime?
The general weekday overtime premium is 50% of ordinary hourly wage, so the total gross pay rate including base pay is 150%.
Q.Where should I check overtime that overlaps another premium condition?
This calculator keeps those hours in overtime pay only. Use the Additional Pay Calculator if the same hours also need another premium included.
Q.Does this calculator split overlapping premium conditions?
No. This page isolates overtime pay only, so it does not show separate cards for overlapping premium conditions. Use the Additional Pay Calculator when the same hours need another premium included.
Q.Should I use this for holiday overtime?
Holiday work has different premium tiers for the first 8 hours and hours beyond 8. Use the Additional Pay Calculator for holiday segments.
Q.Why is the total gross pay lower than the full shift wage?
This page shows gross pay for the hours classified as overtime only. If you worked 13 paid hours and 5 are overtime, the result is based on those 5 target hours, not the full 13-hour shift.
Q.Why is there no daily standard-hours input?
The calculator applies the common daily 8-hour standard internally. Keeping that fixed prevents the individual overtime page from becoming a general shift-pay calculator.
Q.Does break time reduce overtime hours?
Yes. Break time is deducted from the gross shift span before overtime classification. Longer break time can reduce paid work hours and overtime hours.
Q.Can employees under comprehensive wage arrangements use this?
Use it as a reference. Actual additional pay can depend on whether the arrangement is valid, what it includes, and how attendance records support the worked hours.
