Assumptions, sources, currency
Estimates, not financial advice
Your inputs
Salary, monthly spend, net worth, raises, savings rate, return, and horizon.
Currency model
All money values you enter are treated as USD. Tax lookups convert to each tax table's anchor currency using an ECB reference-rate snapshot (as of 2026-07-02).
Salary basis
Salaries are annual gross pay; take-home is estimated per city (see Tax model).

Cost-of-living index
Barcelona: MoveWorth curated index (city-core costs, US avg = 100). London: MoveWorth curated index (city-core costs, US avg = 100). 100 = US average.
Rent baseline
US rent baselines in the Money section prefer the actual measured median (Census ACS 5-Year, table B25031, https://api.census.gov/data/2024/acs/acs5/groups/B25031.html) by bedroom for the city's metro area, falling back to official HUD Fair Market Rents (FY2026, Oct. 1, 2025 to Sept. 30, 2026, https://www.huduser.gov/portal/datasets/fmr.html) where ACS has no data for that city or bedroom size. Non-US rent remains unconnected in v1.
Tax model
Estimated income tax + employee social contributions. US cities use 2025 federal brackets + state + FICA; UK cities use real PolicyEngine income tax + National Insurance (Scotland's separate bands included); elsewhere an OECD-anchored effective rate. Barcelona 32%, London 30%. Household: single. Estimate, not a filing model.
Financial math
Compounded net worth from after-tax savings and expected annual returns.
Uncertainty band
The break-even chart's shaded band reruns your numbers ~300 times, nudging investment return, raises, and cost-of-living growth within typical historical swings. It shows a plausible range, not a guarantee, and is seeded from your inputs so it won't change on reload.
Culture & wellbeing
Life expectancy (World Bank) and life satisfaction (Our World in Data) are live, official per-country figures. Languages, English proficiency band, and marriage-equality status are hand-compiled reference facts, not a live feed — verify before relying on them for a legal decision.
