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.
- All countries checked publish net worth at household level, not individual level. Pension-wealth coverage and survey methods differ, so cross-country ranks are approximate comparisons.
- South Korea uses the latest 2025 Survey of Household Finances and Living Conditions decile breakpoints (survey date March 2025).
- Japan's most recent National Survey of Family Income, Consumption and Wealth (2019, a 5-yearly survey) publishes only a mean and median — no decile breakpoints — so Japan is shown as a ratio rather than a rank.
- Net worth can be negative when debts exceed assets (confirmed at Germany's bottom 5%), and this calculator allows negative input.
A quick reality check
US$300,000 net worth
That is roughly the top 44% of U.S. households and converts to about the top 33% of South Korean households — the highest rank among the countries with a calculable percentile for this amount.
Negative net worth (more debt than assets)
You can enter a negative number. Germany's official data confirms the bottom 5% of households have negative net worth (about −€800).
Common questions
Why household net worth only, not individual?
All 6 countries with official net-worth data publish it at the household level only — real estate, savings and debt are usually shared or jointly held, so no country has an official way to split net worth per person the way it does for income.
Can I enter a negative net worth?
Yes. If your debts exceed your assets, enter a negative number. Germany's Bundesbank survey confirms the bottom 5% of households have negative net worth, and the calculator places negative inputs correctly within that range.
Does this account for cost of living?
No. It's a nominal currency conversion showing where the same net worth sits in each country's wealth distribution — not what that money can actually buy locally (purchasing-power parity is not applied).
