Methodology (expand) Mixed FX resolution — historical annual averages (breakdown & rankings) use World Bank (1988–2024), the monthly trend uses FRED, and the current year (2026) uses daily Frankfurter/ECB. Each period has a different base FX granularity.Minimum wage is annual — flat within each year, steps up every January. Line fluctuations come from FX rate changes.Quote date — today's value uses the last business-day quote; weekends/holidays use the most recent available quote.USD wage = KRW wage / FX rate — the numerator is fixed, only the denominator (FX rate) moves.Year-over-year comparison — all change metrics (hero cards, body) are vs. the previous year.1988 representative value — that year had two industry-group rates (Group 1 ₩462.5 / Group 2 ₩487.5); the lower floor (Group 1) is used.2025 annual average — World Bank has not published 2025 yet, so the 2025 annual average in the breakdown and rankings is gap-filled from the arithmetic mean of FRED monthly values (to be replaced by the final World Bank figure later).Purchasing power — core tabs: naengmyeon ₩12,538 (Mar 2026), jajangmyeon ₩7,692 (Feb 2026), gimbap ₩3,800 (Apr 2026), pork belly 200g ₩21,218 (Mar 2026), kimchi stew ₩8,654 (2026), ramyeon (Shin Ramyun) ₩1,000 (Mar 2025), eggs (30-tray) ₩7,022, rice (20kg) ₩54,000 (KAMIS urban retail), instant rice (210g) ₩1,611, subway base fare ₩1,550 (Jun 2025 raise) from Korea Consumer Agency (Seoul avg; dining, groceries, agri-products) and KAMIS (rice); kalguksu, bibimbap, samgyetang from Korea Consumer Agency (Seoul avg, Mar 2026); Big Mac from McDonald's Korea actual price (Feb 2026 ₩5,700) / The Economist Big Mac Index.Purchasing power — bonus tabs (disclaimer): chicken is Kyochon Honey Combo Seoul delivery app ₩26,000 (2026, delivery fee extra), tteokbokki is Yupdduk basic (~3-person serving, frozen at ₩14,000 since 2012), soju is convenience-store 360ml basis ₩1,900 (mart/restaurant prices differ), americano is Starbucks Tall list price ₩4,700 (budget brands differ). These are reference/fun values.2026 FX is provisional — the 2026 annual average FX rate is not yet finalized, so the YTD average is used. The 2026 annual figure in the hero, main chart, and breakdown is provisional.The time machine mixes resolutions — past points use that month's average FX rate while today uses the live daily rate, so figures are approximate (≈).License: Big Mac data CC-BY 4.0, Korean public data Attribution Type 1.
