What this estimate assumes
- Cross-country comparisons use the 2026-08-14 Korea International Trade Association (KITA) market exchange rate as a simple nominal conversion — cost-of-living and purchasing-power (PPP) differences are not applied.
- Base years (2021–2025), surveying agencies, and the definition of individual vs. household income (combined household, per-member, or equivalised) differ by country.
- South Korea's individual wage-income data comes from the National Tax Service's full 109-band percentile file (tax year 2024, all 21,078,535 wage earners), converted to a standard percentile curve. South Korea's household income data is the combined (non-equivalised) household income deciles from the government's 2024 Survey of Household Finances and Living Conditions (income year 2023).
- Figures are gross (pre-tax) income; they don't reflect each country's tax or social-insurance deductions.
- Some countries or income types only have limited official percentile data available (for example, Malaysia's and Japan's individual income detail, or Singapore's individual income), so those are shown as a ratio to the median/mean instead of a rank, or marked as unsupported rather than estimated.
A quick reality check
US$60,000 (individual income)
That income lands around the top 51% in the United States — meaning it's close to the US median — while the same amount converts to roughly the top 23% in South Korea.
Switching to household income
Household income definitions differ by country (combined household total, per-member, or equivalised for household size), so only countries that publish a comparable measure show a rank.
Common questions
What exchange rate is used?
The Korea International Trade Association (KITA) market rate as of August 14, 2026. Rates move over time, so treat the comparison as a snapshot, not a live figure.
Does this account for cost of living?
No. It's a nominal currency conversion showing where the same amount of money sits in each country's income distribution — not what that money can actually buy locally (purchasing-power parity is not applied).
Why do some countries show 'not supported' or a ratio instead of a rank?
Because their official statistical agencies haven't published a full income-percentile breakdown for that income type, we show what is actually published (a ratio to the median or mean) rather than inventing a percentile.
Can I compare household income figures across countries directly?
Be careful. South Korea, the United States, Hong Kong and Malaysia report combined household income, Singapore reports income per household member, and the UK and Germany report equivalised (household-size-adjusted) income. Treat each country's rank as a within-country reference rather than a strict apples-to-apples comparison.
