Why the HSA beats every other account
A 401(k) is taxed on withdrawal and a Roth is taxed going in. An HSA is never taxed when used for medical costs — and after 65 it works like a traditional IRA for anything else.
The stealth retirement account
Pay medical costs out of pocket, keep the receipts, and let the HSA compound — you can reimburse yourself years later, tax-free. The calculator shows what funding it costs you per paycheck.
