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. Buenos Aires 15%, Madrid 32%. 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.
