How we calculate tax rates: Estimated effective rates assume a $200K/yr retiree drawdown, single filer, all long-term capital gains. US figures include federal LTCG + NIIT + state tax (so Boston shows MA, Miami shows FL, etc.). Your real rate depends on income mix and filing status — run the tax calculator for your numbers.
