An eighth of Korean pay is bonus — lumped into a few months
Special payments are about 12–15% of a regular worker's yearly pay in Korea — and nearly a third of the year's total lands in December and January alone.

A Korean worker’s monthly pay slip is not the same size every month, and it is mostly one line that does it. Beyond the fixed salary sits special pay — bonuses and one-off payments — and it is both a large share of the year and a very uneven one.
About an eighth of pay, and slowly shrinking
Across all industries, special payments have made up between roughly 12% and 15% of a regular employee’s total earnings every year since 2011. The share has drifted down — 15.3% in 2011 to 12.6% in 2025 — but the headline is how big it is at all: something like one part in eight of Korean pay is not the monthly salary.
| Year | Bonus share of pay |
|---|---|
| 2011 | 15.3% |
| 2015 | 13.8% |
| 2020 | 11.9% |
| 2025 | 12.6% |
It arrives in a few months, not twelve
The bigger story is timing. Averaged over full years, the year’s special pay is not spread evenly — it clusters:
| Month | Share of the year’s bonus |
|---|---|
| January | 14.8% |
| December | 14.4% |
| September | 13.0% |
| February | 10.4% |
| … | … |
| May / November | ~4.1% each |
December and January together hold 29% of the whole year’s bonus. Add September and February and four months hold about half of it. The leanest months, May and November, hold about 4% each. So a worker’s December or January pay can tower over their May pay without their salary changing at all.
Why this matters for reading any monthly wage number
This is the mechanism behind a warning we have made before: Korea’s monthly real-wage figures swing hard, and not because pay is really lurching around. The fixed-salary part barely moves month to month. Special pay, three to four times larger in its peak months than in its troughs, is what makes a single month jump — so a one-month figure, or a one-month year-on-year change, is mostly telling you whether a bonus happened to land inside it.
The honest reading of a Korean pay number, then, is an annual one: bonuses are about an eighth of the total, they are shrinking slowly, and they arrive in a handful of months — which is exactly why the annual average, not the monthly headline, is the figure to trust.

Data & Verification Notes
- Data as of
- Sources
- Statistics Korea (KOSIS) — Ministry of Employment and Labor «Survey on Labor Force at Establishments» (사업체노동력조사) — KOSIS 118/DT_118N_MON041·051·054, items 13103110311MD_16 (special payments) ÷ MD_13 (total earnings), regular employees, all industries, all sizes
- Cross-checks
- Bonus share = special payments (특별급여) ÷ total monthly earnings (임금총액) for regular employees, all industries, all sizes. Full calendar years only. The share ran 15.3% in 2011 and 12.6% in 2025 — a slow decline, always between about 12% and 15%
- Month concentration is the average, across full years, of how much of that year's total special pay fell in each month. December 14.4% and January 14.8% together hold 29.2% of the year's bonus; adding September (13.0%) and February (10.4%) reaches about 52% in four months. The thinnest months, May and November, hold about 4% each
- This is why single-month wage figures swing. A month that catches a bonus reads far above one that does not — the fixed-pay part (정액급여) barely moves month to month, while special pay is three to four times larger in its peak months than in its troughs
- Excluded figures
- Why bonuses land when they do. The series carries how much special pay was paid and when, not the reason. The peak months line up with Korea's year-end and its two big holidays, but we are not going to assert from this table that any given payment is a holiday bonus
- Whether the decline is good or bad. A falling bonus share can mean many things — more pay shifted into fixed salary, fewer performance payouts, a changing industry mix. The table does not say which, and we will not guess
- Individual experience. This is the all-industry average for regular employees; a specific workplace can be far above or below it
