Geo-Parity

What a month actually costs in each of 41 countries on a stated income, and what is left over. Sums four lines that are kept from overlapping: rent (measured Eurostat city rents, HUD Fair Market Rents, or the price basket where neither covers a country), the everyday basket EXCLUDING rent (the basket normally contains rent — roughly half of it — so adding a separate housing figure to the full bask

Given a US-denominated annual income and a target country code, returns the effective local purchasing power (income / pppIndex), the lifestyle equilibrium cost (income * pppIndex), and the purchasing power ratio (1 / pppIndex). Figures use real PPP data (World Bank, IMF, OECD, Penn World Table) relative to a US baseline of 1.0.

Convert a base salary from a home country into a cost-of-living-fair local equivalent: S_local = S_base × (I_target / I_home), where I is a US-relative price level. Omit `target` to receive a localized salary matrix across every country in the source — useful for pricing one offer across many markets. Returns USD purchasing-power equivalents, not currency-converted amounts.

Models a country's wage distribution as log-normal, calibrated from World Bank GNI per capita (mean) and the Gini index (spread: sigma = sqrt(2)*normInv((Gini+1)/2)), then returns the survival floor (essentials), statutory minimum (ILOSTAT where available, else curated; null where none exists), median (p50), comfortable (p75), top 10% (p90) and top 1% (p99) bands — each monthly and annual, USD and

MEASURED gross monthly earnings of employees by ISCO-08 major occupation group, from ILOSTAT — median and mean, in USD, PPP dollars and local currency, for 35 countries (a median is published for most of them). This is the site's only measured wage series; calculate_wage_bands is MODELLED, and the two are not interchangeable. Each row also carries the female-vs-male pay gap for that occupation (po

Returns a floor, midpoint and ceiling salary for a broad occupation and seniority in a country, anchored on ILO's measured earnings where they exist and on the modelled national wage ladder where they do not — `basis` says which. Built for the employer side of pay transparency: since 7 June 2026 the EU Pay Transparency Directive has required a starting salary or pay range in the job advert. IT IS

Validate a set of trips against the Schengen Area rule: a non-EU visitor may be present at most 90 days within any rolling 180-day window. Entry and exit days both count as days of presence; overlapping trips are de-duplicated. Returns days used in the current window, days remaining, an overall compliance flag, and the exact first overstay date (if any).

Given a set of cities/timezones and each participant's local working hours, find the longest UTC window where everyone is simultaneously within their working day (DST-accurate), AND score the team's overall timezone friction. Returns the overlap in UTC and in each participant's local time (or null with the best partial coverage), plus a `friction` block: a 0–100 score, grade (Effortless/Manageable

Compute gross-to-net parity between a self-employed contractor hourly rate and an employee (W2/EOR) hourly rate, accounting for self-employment/income tax and self-paid health insurance, and return the break-even contractor rate. Uses transparent effective-rate tax presets per country, all overridable. Estimates only — not tax advice.

Given a user-population breakdown, find the cloud host region that minimizes population-weighted round-trip latency (argmin_j Σ_i P_i × L_ij), and compute the optimal multi-region split (each user region routed to its nearest host). Latency is estimated from great-circle distance via a fibre-propagation model, not measured.

Side-by-side comparison of two countries: US-relative price levels across every dataset (World Bank, IMF, OECD, Penn World Table, consumption basket), the consensus ratio, percent difference, and $100k salary equivalence in both directions.

Given a desired annual net income, compute the freelance hourly and day rate required after taxes, self-paid health insurance, weeks off, and billable utilization. Uses the same per-country effective-rate presets as compare_contract; all overridable. Estimates only — not tax advice.

Count distinct days of presence per country per calendar year and evaluate the generic 183-day rule, the US Substantial Presence Test (weighted 3-year formula), and the UK 183-day tax-year test. Early-warning day counter — not tax advice.

The comprehensive engine: from one travel itinerary it returns (1) Schengen 90/180 tourist-visa status (days used/remaining, first overstay, longest compliant stay), (2) per-country tax-residency risk on each country's OWN threshold and basis — the 183-day rule, Cyprus's conditional 60-day rule (flagged only when you're not 183+ resident elsewhere), the US Substantial Presence Test and the UK tax-

Geo-arbitrage FIRE analysis: given a portfolio and safe withdrawal rate, returns every country where the passive income sustains a lean ($32k US-equivalent/yr), comfortable ($55k), upper ($90k), or luxury ($150k) lifestyle at local purchasing-power prices — plus FIRE numbers per tier, nomad-visa income-floor eligibility, local-currency income, an SWR sensitivity band, (with savings/coast params) y

Estimates local prices for a 32-item everyday basket (rent, pint of beer, groceries, transport, gym, …) in two countries, derived as usPrice × pppIndex^elasticity — non-tradables like rent swing harder across borders than world-priced goods like petrol (Balassa-Samuelson-style model). Returns per-item prices in USD and local currency, category subtotals, and a single-person monthly budget rollup.

Remote Worker Tax Trap radar: evaluates how close a stay is to triggering tax residency (183-day rule with per-country variations across 43 tax jurisdictions) and estimates the tax owed on the FULL annual income if the threshold is crossed — comparing the standard resident effective rate against the country's special expat/nomad regime (Spain's Beckham Law 24%, Portugal's IFICI 20%, Italy's impatr

Quality-of-Life vs Cost matrix: ranks 41 countries by a user-weighted composite of livability metrics (median broadband Mbps, safety, healthcare, air quality, English usability — curated country-level data replacing the discontinued Teleport API) against the monthly cost of single-person essentials at local purchasing-power prices. Returns per-country composite and value scores, lifestyle label fo

Healthcare cost and financial exposure across 41 countries: out-of-pocket spend per person per year (US$), out-of-pocket as a share of all health spending, total health spend per capita (PPP international $), government funding share, physicians per 1,000 and dentists per 10,000. Figures are MEASURED from World Bank and WHO Global Health Observatory series, never derived from a price index: scalin

Housing cost and affordability across countries, built for remote workers. Returns monthly rent plus TWO ratios that together answer the real question: rent as a share of the LOCAL median wage (are locals priced out?) and as a share of YOUR remote income (can you afford it?). The gap between them - `arbitrageGap`, in percentage points - is the single number saying whether a place is cheap FOR YOU;

Digital-nomad visa Income Matcher: given a monthly remote income (any currency) and household size, computes each program's real income threshold (base plus its published per-dependent uplift) and returns the programs you qualify for plus the near misses just out of reach — with duration, renewability, tax notes and official source URLs. Curated summaries — verify with the official source before a

Passport Power: for a given country's passport, returns the visa-free-access score (visa-free + visa-on-arrival + eTA destinations), global rank and percentile among all ~199 passports, and the full destination breakdown by access type with names resolved. Omit country for the ranked league table. Reference data from the open imorte/passport-index-data (public domain) — confirm entry rules with th

For founders/freelancers stretching savings: computes how many extra months of runway relocating to a cheaper hub buys. Burn is split into fixed (location-independent — subscriptions, debt, insurance) and local; only the local slice scales by the target's cost-of-living ratio (city-level where a curated hub is given, else national, incl. Factbook-only countries). Returns the home baseline plus eac

Measured connection quality per country from Cloudflare Radar: median download and upload (Mbps), median idle latency and jitter (ms), and a call-quality verdict derived from latency and jitter rather than bandwidth — a video call fails on latency and jitter long before it fails on throughput, which is why a download figure alone cannot answer “can I work from here”. Aggregated from real connectio

Two questions in one. Given `countries` (two or more), returns the working days those places genuinely SHARE in a year — weekdays on which nobody is on a public holiday — which is the number a distributed team actually plans against and the half of the question timezone-overlap tools never answer: a London/Tokyo team loses roughly three working weeks a year to non-overlapping holidays. Without `co

When a distributed team can actually all work. Joins the two halves no free tool puts together: the weekdays on which NOBODY is on a public holiday (the engine behind compare_public_holidays) and the daily working-hour overlap across the members' time zones (the engine behind find_meeting_slot), evaluated on 15 January and 15 July so daylight-saving asymmetry is visible, and multiplied into conser

What a hire actually costs the employer: the gross wage plus the employer's own social security contributions at the rate OECD Taxing Wages publishes (single earner, no children, 100% of the average wage), applied as a flat rate — the figure employer-of-record services quote for a fee. Pass `gross` (annual USD) for your own figure; without it the wage is the pay-range midpoint for the `occupation`

Two questions in one. Given `countries` (two or more ISO alpha-2 codes), returns side by side: mean weekly hours actually worked per employed person (ILOSTAT, newest year from 2023), average annual hours actually worked (OECD, members only), and the paid leave the law gives mothers and fathers in calendar days with who pays (World Bank Women, Business and the Law 2026). Without `countries`, ranks

What money earns or loses in real terms. Given `countries` (two or more ISO alpha-2 codes), returns side by side: consumer-price inflation (World Bank, latest annual, plus the IMF's monthly year-on-year figure where available), the central-bank policy rate (BIS, newest month; the ECB's single rate for euro-area members, flagged `viaEuroArea`), deposit and lending rates (World Bank, where published

What it costs to send money from one country to another, from the World Bank's Remittance Prices Worldwide survey (newest quarter, CC BY 4.0): the mean total cost — fee plus exchange-rate margin — of sending USD 200 and USD 500 across the providers surveyed on that corridor, the cheapest provider found, and how many were surveyed. With `amount` (USD), a quote at the nearer of the two surveyed band

A fixed pension paid from one country and spent in another, after the exchange rate, the destination's price level and the destination's inflation. Converts `amount` in `currency` at the site's FX snapshot, re-prices it at the destination through the PPP engine (the same price-level comparison as calculate_ppp), and projects it flat at the destination's latest annual inflation for `years` (1-40, d

Whether adults there can bank: the share of adults (15+) with an account at a bank, another financial institution or a mobile-money provider, from the World Bank's Global Findex — a triennial household survey, so the survey year travels with each figure — plus personal remittances received as a share of GDP. Given `countries` (two or more), side by side; without, the 41-country spine ranked by `me

Whether a newcomer can open a personal bank account in a country (`yes`, `restricted` or `no`) with the documents usually asked for from a fixed vocabulary, the statutory deposit guarantee per depositor per bank in local currency AND converted to USD at the site's FX snapshot, the country's instant payment systems from the World Bank's Project FASTT tracker, the EU basic-account right under Direct

Statutory tax schedules from the OECD, compared or ranked. Given `countries` (two or more ISO alpha-2 codes), returns side by side the corporate income-tax rate (combined central plus average sub-national, central only, and a small-business rate where one exists; OECD Corporate Tax Statistics, all 41 spine countries) and, for OECD members, the top personal income-tax rate with the earnings thresho

The World Bank's Women, Business and the Law reading of each country's statute (2026 edition, 41 spine countries). Give `country` for one country: the Legal Frameworks index (0-100), eight topic scores (mobility, workplace, pay, marriage, parenthood, entrepreneurship, assets, pension), the coded answers grouped by topic — can a woman choose where to live, travel abroad, get a job the same way as a

Standard and reduced VAT/GST rates for the 41-country spine, hand-curated from each national tax authority's published page and served with that page's URL and the date it was checked, so a figure can be verified rather than trusted. Given `countries` (two or more ISO alpha-2 codes), returns each country's tax kind and name, standard rate, reduced rates where the authority lists them, registration

What two governments say about going. Give `country` (ISO alpha-2) for one country: the UK FCDO's level (none, all-but-essential to parts, all-but-essential, all travel to parts, all travel) with its latest change and date, the FCDO's passport-validity and visa sentences for British citizens and the health risks it lists, and the US State Department's advisory level (1 exercise normal precautions

What to sort out with a travel clinic, as facts from TravelHealthPro (NaTHNaC, the UK's national travel-health centre) with the source page linked per row: the yellow-fever certificate position (required for all arrivals, required when arriving from a risk country, or none), whether the country itself carries yellow-fever risk, the vaccine names recommended for most UK travellers and for some, and

Measured danger once there. Given `countries` (two or more ISO alpha-2 codes), returns side by side: intentional homicides per 100,000 (UNODC via World Bank WDI) and mean annual PM2.5 exposure in µg/m³ (WDI), each with its observation year, and the INFORM disaster-risk score and band composed for context. Without `countries`, ranks the 41-country spine by one `metric` (`homicide` default, `pm25`),

What the state pension system looks like there, from OECD Pensions at a Glance (members and G20 partners, 33 of the 41 spine countries). Give `country` for one: normal retirement age now and for a 22-year-old entering today, by sex; net and gross replacement rates for a full-career average earner at 50/100/200% of the average wage under mandatory schemes; expected years after leaving work; the sha

Which of the 41 spine countries would let a retiree in, and on what terms — a hand-curated register of retiree, passive-income and deposit routes (kind), each with minimum age, monthly income or deposit threshold in its own currency, duration, renewability, a path-to-residency flag, the official page it was read from and the check date; an entry read from secondary reporting because the official s

Does a fixed monthly pension cover a month of local essentials. Given `amount` and `currency` (default GBP 1,500), returns every spine country ranked by coverage — the pension in USD divided by the country's MODELLED monthly essentials (the site's price basket scaled by the PPP price level, checked against real series and wrong both ways) — with the essentials figure, healthcare out-of-pocket per

What a company's investment is actually taxed at: OECD's forward-looking effective average tax rate (EATR), effective marginal rate (EMTR) and cost of capital for a composite investment under fixed interest and inflation, beside the statutory combined corporate rate from the Rules hub, with the gap in points — what allowances and incentives are worth. `country` for one, `countries` for a side-by-s

What a company in `from` keeps back when it pays dividends, interest, royalties or technical fees to a recipient in `to`: OECD's standard withholding rates for the payer's country and, for the pair, the treaty rate where OECD publishes one, with the saving in points per income type. Direction is the payer's, never reversed; `from` equal to `to` is rejected. A pair with no published treaty rate rep

How long and how much it takes to register a limited company: World Bank B-READY's calendar days and cost to complete company entry for a domestic and a foreign-owned company (cost in local currency with a USD conversion at the site's FX snapshot), whether paid-in minimum capital is required, whether sectors are closed to full private ownership, whether a national-employee quota applies, and wheth

Which of the 41 spine countries would let a founder in, and on what terms — a hand-curated register of founder/start-up routes, investor routes and `kind: "none"` entries, each with its one published money figure and what it is for (`minFunds.basis`: an investment to make, subsistence funds to hold, or funding raised from investors), whether an endorsing body must approve the project, duration, re

How much health system there is per person: medical doctors and nursing and midwifery personnel per 10,000 (WHO Global Health Observatory) and hospital beds per 10,000 (WHO, or OECD where newer — the row names its source), beside the UHC service-coverage index. Density is not access: it says how much exists, not whether a visitor can use it or what it costs. Newest observation at the site's vintag

What full-time centre-based childcare costs a family after benefits and tax, from OECD's tax-benefit model (two children aged 2 and 3, no social assistance or rent supplement): a couple both earning 100% of the average wage and a single parent earning 67%, each as a share of household disposable income, of the average wage, and in local currency per year. OECD members only — 22 of the 41 spine cou

What eating a healthy diet costs per person per day, MEASURED: the World Bank's Food Prices for Nutrition series (the cheapest locally available foods that meet a healthy-diet standard, from International Comparison Program retail prices), 165 of the 186 spine countries.

How long goods take to clear the border and what compliance costs, from World Bank B-READY's International Trade topic (firm-survey averages in the largest business city): days for exported and imported goods to clear all border agencies, the typical cost of complying with export and import requirements as a share of goods value, and the share of firms exporting by parcel. B-READY is a rotating co

How much work paying tax is, from World Bank B-READY's Taxation topic (firm surveys in the largest business city): median hours spent on tax compliance a year, the share of firms filing and paying electronically, weeks to a final audit report and to a VAT refund, the share citing a too-long refund process, the share of social-security taxes in labour cost, and the effective income-based rate firms

How much of government can be done online: the UN E-Government Development Index (0–1) and its three components — Online Service Index, Telecommunication Infrastructure Index, Human Capital Index — for all 41 spine countries, read from the UN E-Government Knowledgebase's country pages because no data file is published. The index measures what government provides online and the infrastructure and s

Whether a foreigner may buy residential property in each of the 41 spine countries: an ownership band (`free`, `restricted`, `leasehold-only`, `prohibited`), the main restrictions in a sentence, whether land itself may be owned, and the headline transfer tax a buyer pays with a note on surcharges and fees — a hand-curated register with the official page and check date per row; an entry read from s

No tuition figures: no ci

Ranks countries by a fit score that blends the livability composite (internet speed, safety, healthcare access, air quality, English — measured, each with its own source year) with how far a monthly budget in USD goes against modelled essentials, using 0–10 weights per dimension (`cost`, `internet`, `safety`, `healthcare`, `air`, `english`; default 5 each).

The registry of every dataset behind the site's figures — price levels, wages, housing, healthcare, holidays, working time, inflation, remittance prices, and the rest. Each carries `updated`, the date it was last REBUILT (a fetcher ran, or a person reviewed it), and — where the dataset knows it — `vintage`, what the figures themselves describe: a year, an edition, a quarter, or the source's own pu

Monthly climate normals from ERA5 reanalysis (2015-2024) via Open-Meteo: mean daily maximum and minimum temperature, average monthly rainfall, and a count of comfortable days. Pass `city` (slug) or `country` (alpha-2) for one place's twelve months — a country answers through a named representative city, because a country does not have one climate. Otherwise cities are ranked by comfortable days, f

INFORM Risk from the European Commission's Joint Research Centre: a 0-10 composite where HIGHER IS WORSE, plus the three dimensions behind it — hazard (exposure to earthquakes, floods, cyclones, drought, conflict), vulnerability (how exposed the population is) and copingCapacity (whether institutions and infrastructure could respond). The last is usually the one that matters when choosing where to

The cash needed to ARRIVE somewhere, as opposed to what a month costs once you live there: the entry fee for a given passport, the first month's rent, the deposit, and a long-stay visa fee where one has been verified against the issuing government. READ `complete` BEFORE `totalUsd`. Rent covers a subset of the country spine and most visa fees could not be verified, so the total is a FLOOR whenever
