Methodology
Savings rates from BLS Consumer Expenditure Survey 2023 for Boston (United States) and BLS Consumer Expenditure Survey 2023 for San Francisco (United States). Median income is the midpoint of the default income band for each city. Rent burden is annualised rent divided by gross median income. Years to FIRE assumes a 25× annual expenses target, saved at the local benchmark rate, with no investment growth — a deliberately conservative proxy for ordering cities, not a forecast.
Comparisons across different currencies should focus on percentages (savings rate, rent burden), not absolute amounts.
