Average Custodial Worker Salary in South Korea for 2026

How much does a custodial worker make in South Korea?

A typical custodial worker working in South Korea brings home around 1,470,041 KRW a month before tax. Entry-level pay starts near 8,614,300 KRW, and the top of the ladder reaches roughly 27,479,000 KRW for the most experienced and specialised people in the role.

The wide gap between low end and top end reflects how much pay can vary inside the same job title. A junior custodial worker working at a small local employer earns very different money from a senior at a multinational. Skills, employer, city and years in the seat all push the number around.

How custodial worker pay ranges in South Korea

A good way to think about salary in South Korea is to look at the distribution rather than the headline average. Half of all custodial workers in South Korea earn less than 18,001,100 KRW a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 11,953,700 KRW (the 25th percentile), and a quarter clear 23,159,200 KRW (the 75th percentile). The middle 50% of custodial workers sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 8,614,300 KRW. The highest stretch to 27,479,000 KRW, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Custodial worker pay by experience in South Korea

Years of experience is the single biggest lever on pay for a custodial worker in South Korea, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical custodial worker salary changes as you move through the career ladder.

The single largest jump on the ladder is from 2 - 5 Years to 5 - 10 Years, where pay rises by about 39%. That is the point at which a custodial worker typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.

Custodial worker pay by education in South Korea

Education sits alongside experience as one of the biggest factors driving custodial worker pay in South Korea. Higher qualifications consistently pull higher salaries, but the size of the gap tends to be smallest at junior levels and widens as people move up. Two people in the same role with the same years of experience but different degrees can end up earning very different money once they reach mid-career.

Custodial worker gender pay gap in South Korea

The gender pay gap is a stubborn feature of almost every labour market, and South Korea is no exception. Male custodial workers in South Korea earn an average of 17,039,100 KRW a year, while female custodial workers earn around 18,001,100 KRW. That works out to a 5% gap in favour of women, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.

Pay raises for a custodial worker in South Korea

Most countries hand out at least some kind of pay raise every year, typically when an employee's contract is reviewed or as a cost-of-living adjustment to keep wages roughly in step with inflation. The rhythm and size of those raises varies hugely between industries.

A typical worker doing this role in South Korea sees a raise of about 10% every 17 months, which works out to roughly 7% on an annual basis. That figure is the typical underlying rate; in years where inflation runs high you can usually expect a bit more, and in flat-economy years a bit less.

Across all jobs in South Korea, the national average raise is around 9% every 16 months.
