An estimate before tax and insurance, for a workplace whose full-time week is five 8-hour days and for weeks with no missed day. Your contract may differ.
How the hourly wage is convertedHow this works
From an hourly wage to a week
The week's pay is the hourly wage × the contracted hours (소정근로시간, the hours in the employment contract), plus the weekly holiday allowance (주휴수당). Under Articles 18(3) and 55 of the Labor Standards Act, a worker on 15 or more contracted hours a week who works every contracted day is paid for one rest day: contracted hours ÷ 40 × 8 hours, at most 8.
This page uses the same arithmetic as the weekly holiday pay calculator on this site, so the two never disagree. It assumes a week with no missed day; if you want to see a week with an absence, use that calculator, which has the box for it.
From a week to a month and a year
A month is (contracted hours + paid holiday hours) × 4.345 weeks, rounded to the nearest hour, where 4.345 is 365 days ÷ 7 ÷ 12. The Ministry of Employment and Labor gives the same formula. For 40 hours a week: (40 + 8) × 4.345 = 208.56, so 209 hours — the month in the minimum-wage notice. At the 2026 minimum wage of 10,320 won that is 2,156,880 won a month.
The monthly pay is the hourly wage × those hours, and the yearly pay is the month × 12. Both are before income tax and social insurance; the salary calculator on this site takes those off.
Overtime and night work
Tick the overtime box to add hours worked beyond the contracted hours and hours worked between 10 pm and 6 am. Article 56 of the Labor Standards Act adds at least 50% of the ordinary wage for each, and for a part-timer's hours beyond the contract, Article 6 of the Act on the Protection of Fixed-term and Part-time Workers does the same; this page takes the hourly wage as that wage. Night hours are already among the hours worked, so only the extra 50% is added for them.
The extra 50% binds workplaces with five or more regular workers. With four or fewer, the ministry's answer is that the hours are paid but the premium does not apply, so untick the five-worker box and the page pays them at the plain hourly wage. The week's overtime and night pay × 4.345 is added to the month.
From a monthly pay back to an hourly wage
Choose “Monthly → hourly”, enter the monthly pay and the contracted hours a week. The page divides the pay by the month's hours from the same rule — 209 for 40 hours — and drops anything under one won. A monthly pay of 2,156,880 won over 209 hours is exactly 10,320 won.
Either way, the result is compared with this year's minimum wage. The check compares the hourly figure only; allowances that do or do not count towards the minimum wage are not sorted out here. The 2027 minimum wage is 10,700 won from 1 January 2027. What you type stays in this browser; the site records only that the tool was used.
2,156,880 won for a 40-hour week: 10,320 won × 209 hours, the figure in the minimum-wage notice. Twelve such months are 25,882,560 won a year, before tax and social insurance.
Why 209 hours?
Because the month includes the paid weekly holiday: (40 contracted + 8 holiday hours) × 365 ÷ 7 ÷ 12 = 208.57, rounded to 209. For a shorter week the page uses the same formula with your hours, so 20 hours a week is (20 + 4) × 4.345 = 104.28, or 104 hours.
Does a shop with four staff pay 1.5× for overtime?
No. The +50% for overtime and night work (Labor Standards Act Article 56) applies from five regular workers. Under five, the extra hours are still paid at the hourly wage. Untick “The workplace has 5 or more regular workers” to see that.
