Pay at South Korea's Top 100 Companies: How Far Public Data Can See

The idea that you can estimate corporate pay from South Korea's National Pension workplace data has been around for years. We actually pulled 6.23 million rows and tried it. Then we checked the results against DART disclosures — the answer key — and the estimate failed at every one of the top 100 companies. There is a single reason why.

First, the actual numbers

The table below is measured, not estimated. It comes from the "Status of Employees" section of annual reports filed with DART, the electronic disclosure system run by South Korea's Financial Supervisory Service: the total annual payroll a company reports itself, divided by headcount. Among listed companies with 1,000 or more employees, we ranked the top 100 by pay.

In the bar at the right of each row, the green segment is the range National Pension data can see; the hatched segment is the range the cap clips off.

Dollar figures are indicative conversions from Korean won at the 2026-08-16 rate of 1 USD = 1,414.43 KRW.

Based on FY2025 annual reports filed with DART. "Excl. executives" deducts the pay of unregistered executives, who count as employees in the disclosures.

How the analysis was done

The National Pension Service (NPS), South Korea's public pension scheme, publishes the number of enrolled members and the premium billed that month for every workplace in the country. Premiums are charged at a flat rate on income, so dividing back out gives income per person.

  1. 01Collect everythingThrough the open API on data.go.kr, South Korea's public data portal, we pulled 12 points in time going back to 2015 — 6.23 million workplace rows. The most recent snapshot alone holds 590,000 workplaces.
  2. 02Work back from the premiumAmount billed ÷ members ÷ contribution rate = average assessed monthly income per person. We read the rate straight from the data for each snapshot — it rose from 9% to 9.5% in 2026.
  3. 03Check against DARTWe pulled disclosed payroll for the 2,999 listed companies, matched on company name, and verified the match against headcount. If a name matches the wrong company, the headcount is wildly off.
  4. 04Measure the errorFor the 1,746 companies with clean matches, we compared the estimates against the disclosed figures.

So how close did it get?

At companies where pay is low, the estimate holds up well. As pay rises, it breaks down fast.

Company pay levelEstimate ÷ actualCompanies
40–60% of the cap1.043126
60–80% of the cap0.933313
80–100% of the cap0.872231
100–120% of the cap0.795112

The cause is the cap on assessed monthly income. National Pension contributions are levied only on the first $4,504 (6,370,000 KRW) of monthly income. Someone earning $4,242 (6,000,000 KRW) a month and someone earning $21,210 (30,000,000 KRW) a month pay the same premium. In the data, the two end up as the same number.

And all 100 companies sit above it.

Even the 100th company in this table pays more than the cap. National Pension data alone therefore cannot rank pay at large companies — the limit is structural, not statistical. No correction formula fixes it: information that has been clipped off cannot be restored.

So what is this data good for?

Where DART cannot see. Fewer than 3,000 companies file annual reports, while the National Pension data covers 590,000 workplaces. Unlisted small and mid-sized firms, and month-by-month changes in headcount, are visible nowhere else. Paradoxically, this data works best everywhere except at the largest companies.

What to keep in mind

DART's "average pay per employee" is not a perfect answer key either. The numerator includes pay disbursed to people who left during the year, and the denominator differs from company to company — year-end headcount at some, average headcount over the year at others. "Employees" in the disclosures includes unregistered executives, which pushes the average up (the "Excl. executives" column in the table nets that out). These are pre-tax totals, not take-home pay.

Every figure in this article is either reproduced from published material or calculated by the method described, and all of them are company-level averages, not the pay of any individual worker.
