About Net Life Value

What we do

Net Life Value (NLV) helps you answer one question: where does your salary buy you the best life? We compare 36 countries and 38 cities across taxes, cost of living, real prices, climate, safety, healthcare, internet, and accessibility — and combine everything into a single 0–100 score using the geometric mean of two pillars: Economic Power and Quality of Life.

Where the data comes from

Every number on this site comes from a primary, official source:

• Tax brackets: 30 national tax authorities (IRS, HMRC, DGFiP, BMF, ATO, CRA, ...) — manually maintained tax engines, not estimates
• Cost of living & price levels: World Bank ICP, OECD PPP, plus 15 official statistics offices for city-level data (BEA, ISTAT, IBGE, e-Stat, Destatis, INE, GUS, ABS, StatCan, INSEE, ONS, BFS, ...)
• Healthcare: WHO Global Health Observatory (life expectancy, physicians per capita, hospital beds, health expenditure)
• Safety: UNODC homicide statistics, IEP Global Peace Index
• Internet: ITU (penetration rate, fixed broadband subscriptions)
• Climate: Open-Meteo Historical Weather API (city-level, decade averages)

When official data isn't published or is too coarse, we use Numbeo as a fallback for city-level cost-of-living and rent multipliers — and we tag the source on every city profile.

Editorial summaries (the "who should consider this country" sections, NLV briefs, comparison narratives) are generated by Google's Gemini language model from the underlying numerical data, then fact-checked programmatically against the source figures. Read the full methodology →

Why we built this

Most relocation comparisons stop at "tax rate" or "cost of living index". Both are misleading on their own: a 0% tax country can be unaffordable, and a low cost of living often hides a low ceiling on income. NLV combines them into one defensible number using the same principle as the UN Human Development Index — a geometric mean of two equally weighted pillars, so a country can't mask a weak area with a strong one.

Who runs this

Net Life Value is operated by REAUMUR SAS, a French company based in Paris (9 rue des Colonnes, 75002 Paris). We are an independent team of two — focused on data tools that take both the science and the user's time seriously. We are not affiliated with any government, tax authority, or relocation service.

Important disclaimer

NLV provides estimates for informational and educational purposes only. Tax calculations are simplified and may not account for all deductions, credits, treaties, or individual circumstances. Quality-of-life scores use official data but their weighting is inherently subjective. This is not financial, tax, immigration, or legal advice.
