The counterintuitive result: HDHP wins at both extremes
Very healthy people win on premium savings plus HSA tax breaks. Very heavy users win because both plans hit their out-of-pocket maximums — and the HDHP's max is often similar while its premiums stay lower. PPOs only win in the moderate-spend middle band.
- • Check each plan's out-of-pocket maximum — that's your true worst case.
- • HSA funds roll over forever; FSA funds mostly expire.
- • Employers often seed HSAs with $500–1,000 — free money that tilts the math.
FAQ
Is an HDHP worth it if I rarely go to the doctor?
Almost always yes. A $200/mo premium gap is $2,400/yr saved, plus up to ~$1,300 in HSA tax savings — you'd need to burn through the entire deductible every year just to break even.
What if I have a chronic condition?
Run both plans at your actual spend. Heavy users often still win on HDHP because both plans converge at their out-of-pocket max, but the HDHP premiums and HSA break keep flowing. Compare the maxes, not the deductibles.
Can I invest my HSA?
Yes — after a cash threshold (often $1,000–2,000), most HSA custodians offer mutual funds. Invested HSAs are the only triple-tax-advantaged account in the tax code.
