Executive Summary

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 Parameters

Annual Cash Outflows (Moderate Utilization)

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.

Zion Plan Details

• 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

What Zion Doesn't Cover (OOP $800 estimate)

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)

Investment Assumptions

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.

Why HDHP+HSA Still Wins Long-Term Despite Lower Zion Costs

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.

When Zion Wins

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.

The Structural Risk Zion Carries That The Model Cannot Price

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.

Summary

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.
