What about cost-of-living adjusted — does San Francisco still win?+
Yes. Savings rate already factors in the local cost of living, because it is calculated as (income − expenses) ÷ income using BLS Consumer Expenditure Survey 2023. San Francisco's 26% rate is the cost-adjusted figure — it already reflects what residents actually save after paying rent and other expenses. The 3 percentage-point lead over London is real, not a currency illusion.
Methodology
Savings rates from ONS Living Costs & Food Survey FYE2024 for London (United Kingdom) 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.
