No signup. No tracking. Run entirely in your browser.

All four tools are free, run entirely in your browser, and store nothing about you. Each one places your input on the actual statistical distribution it sits inside, using published sources such as the World Inequality Database, the Federal Reserve's Survey of Consumer Finances, the Eurosystem Household Finance and Consumption Survey, and World Bank consumer-price data. Where corrections are needed, the method is documented by country. The math is published. The refusals are honest.
