This report extends the PPO vs HDHP+HSA comparison by adding a third path: Zion Health Share, a health sharing ministry with no regulatory premium floors. For an incredibly healthy family willing to accept the structural risks of a non-insurance product, Zion's $334/month plan dramatically cuts annual outflows — freeing capital to invest in a taxable brokerage account.
The result is a genuine three-horse race. Zion beats the PPO by $677K over 30 years and trails the HDHP+HSA by $271K — but the gap narrows or reverses if you factor in catastrophic risk, claim denial, or shorter time horizons.
| Plan | Premium | OOP | Tax Savings | Net Annual Cost | Invests |
|---|---|---|---|---|---|
| Traditional PPO | $7,312 | $3,500 | — | $10,812 | $0 |
| HDHP + HSA | $5,000 | $6,000 | −$2,298 | $8,702 | $8,750 into HSA |
| Zion ($5k IUA plan) | $4,008 | $800 | — | $4,808 | $6,004 into taxable |
The Zion "investment" is the delta vs what the same family would have paid on the PPO — the money that was freed up by choosing the cheaper plan, redirected into a brokerage account.
- Source: Zion HealthShare 2026 pricing
- Plan selected: $5,000 IUA tier — cheapest option
- Monthly cost (family): $334/month = $4,008/yr
- IUA (Initial Unshareable Amount): $5,000 per incident — Zion's equivalent of a per-incident deductible
- IUA cap: Maximum 3 IUAs in a rolling 12-month period = $15,000 max household exposure
- Scenario assumption: Incredibly healthy family — zero IUA events triggered per year
Health shares are not insurance. The $800 annual OOP allowance covers items Zion typically excludes from sharing:
- Preventive care / annual physicals (not a "medical need")
- Generic prescriptions ($4–10/month for common medications)
- Dental and vision
- Mental health (varies by plan)
| Account | Annual Contribution | Real Return | Tax Treatment |
|---|---|---|---|
| HSA (HDHP path) | $8,750 | 7.0% | Triple tax-free + FICA bypass |
| Taxable brokerage (Zion path) | $6,004 | 6.5% | Dividends taxed annually; LTCG at 15% on liquidation |
The taxable account earns slightly less (6.5% vs 7%) due to dividend tax drag on an S&P 500 index fund (~1.3% yield × 15% = ~0.2% annual drag). Capital gains are deferred until sale, so the account is modeled as a buy-and-hold position with 15% LTCG applied to all gains at Year 30 liquidation.

Zion vs HDHP+HSA: −$271,090 (HDHP+HSA wins at 30 years)
Zion spends $6,462/yr less than the HDHP path. Yet the HDHP+HSA ends $271K ahead. Two compounding effects drive this:
1. Contribution size advantage
The HDHP path forces $8,750/yr into the HSA (including the $1,000 employer match). The Zion path only invests $6,004/yr — the premium savings delta. The HSA contributes $2,746/yr more, compounding at 7% real for 30 years.
2. Tax-free compounding
Every dollar of HSA growth is permanently sheltered. The taxable account loses roughly 15% of all gains to LTCG at liquidation — that's approximately $83K in taxes paid at Year 30 on a $580K gross balance to get to $496K net. The HSA pays nothing.
The crossover point
Zion leads in net advantage vs PPO for the first ~7 years (lower cost, less compounding needed). After Year 8, the HSA's tax-free compounding overtakes and the gap widens permanently.
Short time horizon (under 8 years): The premium savings advantage dominates before compounding kicks in. If you're 5 years from retirement, Zion's cash-flow benefit is immediate and real.
Higher tax bracket: At 37% federal + FICA, the HSA tax savings rise to ~$3,400/yr — but LTCG on the taxable account is also 20%. The relative advantage of HSA grows, but both paths scale up.
If the employer offers no HSA match: Removing the $1,000 employer HSA contribution narrows the gap to ~$230K at Year 30.
This is the critical caveat. Health sharing is not insurance and carries risks that don't show up in a financial model:
- No statutory OOP cap. The $15,000 IUA cap is a guideline, not a legal guarantee. A denied claim doesn't cap your exposure.
- Claim denial risk. Zion and other health shares have discretion to deny claims. Common exclusions: pre-existing conditions (often a 12–24 month waiting period), mental health, substance use, certain preventive procedures.
- Not ACA-compliant. You can use a health share during an ACA open enrollment period without penalty, but it doesn't count as "minimum essential coverage" in states that have their own individual mandates.
- Catastrophic scenario. A major illness or accident in Year 1 — before your taxable account has grown — leaves you with a $15,000 IUA exposure plus potential uncovered costs, vs. the HDHP's hard $16,600 statutory OOP maximum that must be honored by law.
- Solvency risk. Health shares are not backed by state insurance guarantee funds. If the sharing pool runs dry, claims may go unpaid.
The model shows Zion trailing HDHP+HSA by $271K over 30 years on pure math. If you assign even a modest probability to one major denied or uncovered claim, the expected value gap widens further.
For an exceptionally healthy family with a long time horizon, strong liquidity, and comfort with the structural risks of non-insurance products, Zion is a legitimate option that destroys the PPO and comes respectably close to the HDHP+HSA path.
For anyone who wants the wealth-building benefits of tax-advantaged compounding and the legal protections of regulated insurance, the HDHP+HSA remains the dominant long-term choice — by $271K over 30 years even against Zion's rock-bottom premiums.
