About Geo-Parity

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 — 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 — 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 — Score a distributed team's timezone overlap (0–100), find the golden-hour everyone shares, and flag the isolated 'lone wolf'.
• Freelance Rate 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 — Pick the cloud region that minimizes latency for your real user base — and see whether a multi-region split pays off.

• Cost of Sending Money Home — What a transfer really costs on your corridor — fee plus exchange-rate margin, average and cheapest provider — from the World Bank's quarterly survey.
• Pension Paid Abroad — What a pension is worth in another country after the exchange rate and price level, and how fast local inflation erodes it.

• Healthcare Costs & Exposure — What healthcare actually costs per person, how much of it comes out of your own pocket, and how many doctors and dentists there are — real figures, not scaled from a price index.
• What It Costs to Arrive — 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 — 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 — 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, the tool manifest at /.well-known/mcp.json, and the full specification at /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 for the full disclaimer.

The country flags are drawn with Twemoji, © Twitter, Inc. and other contributors, used unmodified under CC-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 — 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.

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.
