Methodology
How we estimate your income position and which data we use.
Median ratio
Your salary is divided by the national median household income. A value of 1.0 means you are at the median; above 1.0 means you earn more than the typical household, below 1.0 means less.
Estimated percentile
Income distributions are often well approximated by a log-normal distribution. We use the country’s median (location) and mean (scale) to approximate the distribution’s shape, then compute the cumulative distribution function (CDF) at your salary to estimate the share of households earning less than you. The result is reported as a percentile (0–100).
Percentage above or below average
We compute (your salary − national mean) / national mean and express it as a percentage. Positive values mean you are above the national average; negative means below.
Data sources
The underlying concepts and typical ranges for median, mean, and inequality (Gini) are inspired by:
- World Bank — household income and inequality statistics.
- OECD — income distribution and median/mean income data.
All amounts on this site are expressed in USD equivalent for cross-country comparability. The figures are illustrative and are not real-time; they may not match official published values.
