What this tool does
This calculator tells you exactly where your income places you in the global wealth distribution. By entering your annual income and selecting your country, you instantly see what percentage of the world's population earns less than you do — a number that is almost always surprising.
Most people in wealthy countries dramatically underestimate how rich they are by global standards. If you earn a typical salary in the United States, Canada, Australia, or Western Europe, you are almost certainly in the top 5% to 15% of all income earners on Earth. The calculator makes this concrete with three key metrics: your global percentile, how your income compares to the global median, and how much you earn each day compared to what billions of people earn in an entire year.
Results are calculated using purchasing power parity (PPP) adjustments, which account for differences in cost of living between countries. This provides a more accurate picture of real-world wealth than simply converting currencies at market exchange rates.
How it calculates
The calculator uses two steps to determine your global wealth percentile.
**Step 1 — PPP Adjustment**
Your nominal income in USD is adjusted using each country's purchasing power parity factor. For example, \$10,000 in India buys considerably more than \$10,000 in the United States because prices are lower in India. The PPP adjustment normalizes incomes across countries so they can be compared on a level playing field.
PPP factors are sourced from World Bank International Comparison Program data. A country with a PPP factor of 0.5 means local prices are about half of US prices, so incomes are effectively multiplied when comparing globally.
**Step 2 — Percentile Interpolation**
Your PPP-adjusted income is plotted against the global income distribution using the following breakpoints derived from World Bank and Pew Research data:
- Bottom 10%: under \$500/year PPP - Bottom 50% (global median): under \$3,920/year PPP - Top 20%: above \$8,000/year PPP - Top 10%: above \$15,000/year PPP - Top 5%: above \$25,000/year PPP - Top 1%: above \$60,000/year PPP
Between breakpoints, the tool interpolates linearly to produce a smooth percentile value.
Why this matters
Global income inequality is one of the most significant and least-understood facts about the modern world. The gap between the wealthiest and poorest people on Earth is staggering, and most people in high-income countries have no intuitive sense of where they stand.
Understanding your global position has real implications for how you think about taxation, foreign aid, charitable giving, and economic policy. Research by philosopher Peter Singer and economists like Branko Milanovic has shown that even modest income transfers from the global rich to the global poor can have enormous impacts on wellbeing, precisely because of the vast income gaps this calculator reveals.
This tool is not meant to induce guilt — it is meant to provide perspective. Knowing that your income places you in the global top 10% or top 5% is simply useful information for making informed decisions about how you engage with the world.

Understanding PPP
Purchasing Power Parity (PPP) is an economic concept used to make income comparisons across countries meaningful. Because the cost of goods and services varies enormously between countries, a simple currency conversion can be misleading.
For example, a software engineer in India earning \$15,000 USD equivalent per year may live very comfortably — that salary goes much further in Mumbai than it would in San Francisco. PPP adjustments attempt to normalize for these differences by measuring how much a standardized basket of goods costs in each country.
The World Bank publishes updated PPP factors for all countries. This calculator uses those factors to convert your nominal income into a PPP-adjusted figure that is comparable across borders. Note that for the United States, the PPP factor is 1.0 — it is the reference currency.
FAQs
**Q: Should I enter gross (pre-tax) or net (after-tax) income?** A: Enter your gross pre-tax income for comparison with most global income statistics, which also use pre-tax figures. Most international income surveys collect gross income, so this produces the most accurate comparison.
**Q: Does this account for wealth (assets) or just income?** A: This calculator measures income — the money you earn per year — not wealth, which includes assets like real estate, savings, and investments. The global wealth distribution is even more unequal than the income distribution. Someone with substantial assets but low current income would score lower than their true economic position.
**Q: How accurate is the PPP data?** A: PPP factors are sourced from World Bank International Comparison Program data and are updated periodically. They provide a reasonable approximation for comparison purposes but are not perfectly precise for every individual situation. Cost of living varies enormously within countries as well as between them.
**Q: What does "global median income" mean?** A: The global median income is the income level at which exactly half the world's population earns more and half earns less. As of the most recent World Bank data, this is approximately \$3,920 per year in PPP-adjusted terms — about \$10.74 per day. This number is striking because it means half of humanity lives on less than \$11 per day.
**Q: Why is the top 1% threshold only \$60,000/year?** A: Because the vast majority of the world's population lives in countries with much lower average incomes than the US, UK, or other high-income nations. The global top 1% is calculated across all 8 billion people on Earth, and \$60,000 per year places you well above the income of people in most of Asia, Africa, and Latin America, even after PPP adjustment.
**Q: Is my data stored or sent anywhere?** A: No. All calculations happen entirely in your browser. No income data is transmitted to any server.
