Korea Part-Time Pay Calculator — Weekly Holiday Allowance and Night Pay
Calculate monthly part-time pay in Korea from an hourly wage and weekly hours, including the weekly holiday allowance.
How part-time monthly pay is calculated
- Base pay = hourly wage × weekly hours × 4.345. 4.345 is the average number of weeks in a month (365 days ÷ 7 days ÷ 12 months ≈ 4.3452).
- Weekly holiday allowance = hourly wage × (weekly hours ÷ 40 × 8 hours) × 4.345. At 40 hours a week or more the paid holiday counts as 8 hours. This conversion is the method the Ministry of Employment and Labor explains.
- Night premium = night hours × hourly wage × 0.5 × 4.345. Work between 10 pm and 6 am the next day must be paid at least an extra 50% of the ordinary wage (Labor Standards Act, Art. 56(3)). The base pay for those hours is already in the base pay above, so only the premium is added.
- Social insurance (employee share) — National Pension 4.75%, health insurance 3.595%, long-term care (about 13.14% of the health premium), employment insurance 0.9%. Premiums are rounded down below ₩10, and the National Pension uses an income base rounded down below ₩1,000 and kept between a floor of ₩410,000 and a ceiling of ₩6,590,000.
When you get the weekly holiday allowance
- You must work an average of at least 15 hours a week. If the four-week average is under 15 hours there is no weekly holiday allowance (Labor Standards Act, Art. 18(3)).
- You must attend every scheduled working day of that week (Enforcement Decree, Art. 30(1)). In a week with an absence there is no allowance.
- Art. 55(1) is the rule that an employer must give at least one paid day off a week on average.

₩10,320 is the minimum hourly wage that applies this year (Ministry of Employment and Labor "2026 minimum wage notice", hourly wage ₩10,320 (confirmed by the Minimum Wage Council)). The table is calculated with the same function as the calculator on this page and rounded to the won. At 15 hours a week the paid holiday counts as 3 hours (15 ÷ 40 × 8).
If you work nights
If you work 20 hours a week and 10 of them are at night, the night premium at the minimum wage is ₩224,202 a month. Night hours are part of your working hours, so include them in the weekly hours you enter.
What this calculation does not include
- Overtime and holiday work — hours beyond 40 a week must be paid at 150% of the ordinary wage (Art. 56), so this calculator only accepts 40 hours or fewer.
- Income tax — for employment income it is withheld using the simplified table based on monthly pay and dependents, and for a freelance contract it is withheld separately at 3.3%. This calculator does not include income tax. For take-home pay from an annual salary, use the take-home pay calculator, which uses the simplified table.
- Workplaces with fewer than 5 employees — only some provisions of the Labor Standards Act apply (Art. 11(2)). Whether premium pay applies depends on the size of the workplace.
- Whether you must be enrolled in the four social insurances, and deductions for lateness or absence, are not reflected.
- Foreign employees — whether your visa allows part-time work, and for how many hours a week, is a separate rule that this page does not check (international students, for example, usually need permission first). Ask your school, your employer or the immigration office before you start.
Basis: National Law Information Center — Labor Standards Act, Arts. 11, 18, 55 and 56, Enforcement Decree of the Labor Standards Act, Art. 30; Ministry of Employment and Labor "2026 minimum wage notice", hourly wage ₩10,320 (confirmed by the Minimum Wage Council); National Pension Service — 9.5% in 2026 (4.75% each), rising 0.5 percentage points a year from 2026; Half of the Ministry of Health and Welfare announcement "2026 health insurance rate set at 7.19%" (checked October 2026). This is an estimate; your contract and payslip are what count.
Frequently asked questions
How is the weekly holiday allowance calculated?
Hourly wage × (weekly hours ÷ 40 × 8 hours). At 20 hours a week the paid holiday counts as 4 hours, so at the minimum wage of ₩10,320 it is ₩41,280 a week. You need at least 15 hours a week and full attendance on your scheduled days.
Is there no weekly holiday allowance if I work only 14 hours a week?
Correct. If your scheduled hours average under 15 a week over four weeks, the weekly holiday rule does not apply (Labor Standards Act, Art. 18(3)). That is why many workplaces sign contracts of 14 hours a week or fewer.
How can I tell whether my monthly pay already includes the weekly holiday allowance?
Check the pay components in your employment contract (base pay, weekly holiday allowance and so on). If you set the allowance to "Exclude" in this calculator you see the base pay alone, so you can compare it with the amount in your contract.
Is what I enter saved?
No. The calculation happens only in your browser; nothing is sent to a server or stored.
I am a foreign national. Is the minimum wage the same for me?
The minimum wage is set by law for employees working in Korea. Whether your visa lets you work part-time at all, and for how many hours, is a separate question that this page does not check. Confirm it with your school, your employer or the immigration office.
What does "juhyu-sudang" on my contract mean?
It is the weekly holiday allowance: pay for one paid day of rest each week, given to employees who work at least 15 hours a week and attend every scheduled day. Many monthly figures in job ads already include it, so check whether the amount you were told is with or without it.
Why does the calculator use 4.345 weeks a month?
A year has 365 days, which is about 52.14 weeks, and dividing by 12 months gives about 4.345 weeks in an average month. Using it keeps the monthly figure the same whether a month has four or five weeks.
