About

# About Geo-Parity

Geo-Parity is a free suite of geographic-parity tools for remote work, global pay and travel — what your money is really worth abroad, a cost-of-living-fair salary, how far savings stretch, visa and tax-residency limits, cross-timezone meeting overlap, and lowest-latency cloud regions.

## Why it exists

Money doesn't mean the same thing in every country, and most online calculators quietly assume the United States. Geo-Parity treats every country as a first-class home base: pick where you are, and every figure is shown in your own currency, on real purchasing-power data. The goal is honest, comparable numbers for people living and working across borders — and for the AI agents increasingly doing that research on their behalf.

## What's inside

- [Cost of Living & Salary Comparison](https://geo-parity.com/) — What your income is worth abroad, two countries side by side, and a cost-of-living-fair salary — in your currency, on real World Bank/IMF/OECD/PWT data.
- [Local Salary Benchmarker](https://geo-parity.com/wage-bands/) — The real local wage ladder — survival, minimum, median, top 10%, top 1% — for setting fair bands or seeing where you stand.
- [Team Timezone Friction Scorer](https://geo-parity.com/meeting-planner/) — Score a distributed team's timezone overlap (0–100), find the golden-hour everyone shares, and flag the isolated 'lone wolf'.
- [Freelance Rate Calculator](https://geo-parity.com/contractor-calculator/) — Contractor-vs-employee break-even and the hourly/day rate you must charge to hit a target net income — localised to your currency.
- [Cloud Region Selector](https://geo-parity.com/cloud-region-selector/) — Pick the cloud region that minimizes latency for your real user base — and see whether a multi-region split pays off.

- [What It Costs to Arrive](https://geo-parity.com/expenses/?tab=arrival) — The cash you need before you have a life somewhere: the entry fee for your passport, the first month's rent and the deposit. Says which parts it could not price rather than quietly leaving them out.
- [Housing Costs & Affordability](https://geo-parity.com/expenses/?tab=housing) — What rent costs against your remote income and against local wages — the gap between the two is the arbitrage. Plus price-to-income, price-to-rent and mortgage rates.
- [Global Mobility — Visas & Passports](https://geo-parity.com/nomad-visas/) — Which nomad visas your income qualifies you for, plus how far your passport already takes you visa-free — two sides of mobility in one tool.

## Built for humans and AI agents

Every tool is also a machine-readable service. Each has an open JSON API (CORS-enabled, no key required) and an MCP tool, so an AI assistant can answer "what's a fair Berlin salary for a $120k US role?" directly. The capability index lives at [/llms.txt](https://geo-parity.com/llms.txt), the tool manifest at [/.well-known/mcp.json](https://geo-parity.com/.well-known/mcp.json), and the full specification at [/openapi.json](https://geo-parity.com/openapi.json).

There is also a live **MCP server** at `https://geo-parity.com/api/mcp`, exposing all 62 tools to any Model Context Protocol client — Claude, ChatGPT, Cursor, Copilot and the rest. It needs no account, no key and no sign-up. Add it with:

```
`claude mcp add --transport http geo-parity https://geo-parity.com/api/mcp`
```

Every tool returns the same figures as its JSON endpoint — they are the same code, not two implementations — and each result carries a citation and a link back to the page that answers the same question.

## Data & methodology

Price levels and purchasing-power figures are blended from the **World Bank**, the **IMF World Economic Outlook**, **OECD** and the **Penn World Table**, taken as a per-country median and refreshed at build time. Other tools draw on published wage data, passport visa-free access indices, and quality-of-life indicators (internet speed, safety, healthcare, air quality). Every result is a model estimate, not a quote — see the [Terms](https://geo-parity.com/terms/) for the full disclaimer.

The country flags are drawn with [Twemoji](https://github.com/twitter/twemoji), © Twitter, Inc. and other contributors, used unmodified under [CC-BY 4.0](https://creativecommons.org/licenses/by/4.0/). They are served from this site rather than left to your device, because Windows ships no flag glyphs and would otherwise show two grey letters in their place.

## How it's funded

Geo-Parity is free to use, and the JSON API stays open and key-free. Funding comes from two places. First, optional [paid plans](https://geo-parity.com/pricing/) — Pro, higher API limits, and a one-off dataset — billed through Polar. Second, affiliate and sponsored links to relevant services (global payroll, nomad insurance, money transfer, and similar), where the operator may earn a commission at no extra cost to you. Neither changes the underlying data or which option a calculation recommends: paying gets you convenience, never different numbers. Full detail is in the [Affiliate & Sponsorship Disclosure](https://geo-parity.com/disclosure/).

## Who runs it & contact

Adam Simmons-Spaans — Founder, Geo-Parity. Adam builds Geo-Parity single-handedly: the engines, the datasets and the fetchers that refresh them. Every figure on the site comes from a published source — World Bank, IMF, OECD, Eurostat, WHO, HUD, Cloudflare Radar — and where a number is modelled rather than measured, the page says so.

Geo-Parity is operated by Adam Simmons Spaans (United Kingdom). Questions, corrections or data-source suggestions are welcome at [info@geo-parity.com](mailto:info@geo-parity.com).
