About WorthParty

Published September 6, 2026

WorthParty is a free calculator that puts a net worth in context: what percentile it lands in worldwide, how it compares within an age bracket or a country, and how far it sits from a financial-independence target. You type one number; everything else is computed on the page, in your browser, from public data.

Why this exists

Most coverage of wealth quotes averages, and averages mislead — a handful of very large fortunes drag the mean far above what a typical person holds. The median adult worldwide has on the order of $8,000; the mean is roughly ten times that. Percentiles are the honest lens: they tell you where a number actually stands among people, not where it stands relative to a distorted midpoint.

The tools that did offer that context tended to want something in return — an account, an email address, linked bank logins. That trade seemed unnecessary for what is ultimately arithmetic on published survey data. So WorthParty runs entirely client-side: no accounts, no database, and nothing you type ever leaves the page. The privacy policy is short because there is genuinely nothing to disclose.

Where the numbers come from

Every figure on this site traces to a public source and a stated formula:

• Global and country wealth distributions — UBS Global Wealth Report and Databook.
• US net worth by age — the Federal Reserve's Survey of Consumer Finances (2022).
• US metro living costs — derived from the Bureau of Economic Analysis's Regional Price Parities, covering all 387 metro areas.
• US wages and home values — BLS Occupational Employment and Wage Statistics and Census ACS.

The methodology page documents every formula and its limitations, and the derived datasets are published as plain JSON under /data for anyone to check or reuse. When a number is a rounded editorial estimate rather than a derived figure, it is labeled as one.

Who makes it

WorthParty is built and maintained by one person — Barath, a software engineer in the United States. It is a side project, kept free and supported by ads. Data gets refreshed with each yearly release of the underlying sources, and corrections are folded in as readers report them.

How it's built

The site is deliberately plain: hand-written HTML and JavaScript, no framework on the public pages, no build step between the source and what your browser receives. That keeps pages fast, keeps the privacy promise auditable — you can read the entire source with View Source — and keeps the project maintainable by one person. Percentiles are interpolated on a log scale between published anchor points; peer distributions are fitted log-normal curves from each group's median and mean. Every release runs an automated test suite over the math, the data files, and the pages themselves before anything ships.

What this is not

WorthParty is perspective, not advice. Wealth surveys carry wide error bars, currencies move, and a log-normal fit is good to a few percentage points — the site says so wherever it applies. Nothing here accounts for your tax situation, your market, or your life; treat the output as a well-drawn map, not a survey marker.
