What This Analysis Doesn't Include

Your actual tax drag

We assume baseline SWR. Your real post-tax income depends on account mix (Roth/traditional/taxable), Social Security, and where funds are held.

Healthcare pre-Medicare

The healthcare line uses local averages. US expats pre-65 often face much higher costs; EU and Thai retirees often much lower.

Sequence of returns risk

A 4% rule works historically — but not if your first decade has bad returns. See our sequence risk guide.

Currency & visa

FX swings and visa renewal requirements change the math for non-nationals. Research the specific visa pathway to United States before committing.
