Direct Primary Care vs Insurance: Annual Math

A direct primary care (DPC) membership costs a single adult roughly $600–$1,200 per year. Add a bare-bones high-deductible health plan, and the combined annual premium can still run $3,000–$5,000 less than the average employer-sponsored PPO worker contribution — before accounting for the health savings account (HSA) tax advantage that kicks in on top. The math is compelling. Whether it holds for a $150k+ household depends entirely on utilization patterns, specialist needs, and how aggressively the HSA is managed.

What the DPC Model Actually Costs

Direct primary care eliminates the insurance billing layer at the primary care level. Members pay a flat monthly fee directly to their physician; the practice drops insurance contracts entirely. According to the American Academy of Family Physicians (AAFP) 2024 DPC Data Brief, monthly membership fees for individual adults range from $50 to $100, with children typically running $20–$49 and family bundles starting at $100 per month. At the median, a dual-adult household pays roughly $150–$200 monthly — $1,800–$2,400 annually — for unlimited primary care visits, same-day access, and extended appointment times averaging 30–60 minutes.

That retainer covers preventive care, chronic disease management, minor procedures, and routine labs at cost. What it does not cover: specialist visits, hospitalizations, imaging at outside facilities, and emergency care. Those exposures require a companion insurance policy — almost universally, an HDHP for anyone pairing DPC with tax-advantaged savings.

For the concierge medicine cost comparison, DPC sits well below the concierge tier. Concierge practices layer a retainer — typically $1,500–$3,000+ annually — on top of normal insurance billing, meaning they generate revenue from both the member fee and the insurer. DPC practices do not bill insurance at all. That distinction matters for both pricing and the HSA compatibility rules described below.

The HDHP Companion Plan: What It Costs and What It Limits

Per the KFF 2025 Employer Health Benefits Survey, employees in HDHP/savings option plans paid average premiums of roughly $8,275 for single coverage and $24,196 for family coverage in 2024, well below the overall averages of $9,325 single and $26,993 family reported in 2025. Worker contributions followed the same pattern: the average employee share for all employer plans ran $1,440 single and $6,850 family in 2025.

The trade-off is front-loaded cost exposure. Under IRS Revenue Procedure 2025-19, an HSA-qualified HDHP must carry a minimum deductible of $1,700 for single coverage and $3,400 for family coverage in 2026. The deductible arrives before the plan pays for most non-preventive services — the gap that DPC retainers are specifically designed to fill at the primary care layer. If the household also carries a DPC membership covering the 80–90% of healthcare encounters that originate in primary care, the deductible risk concentrates in specialist and hospital events rather than routine care.

The HDHP out-of-pocket maximum in 2026 is $8,500 for single coverage and $17,000 for family coverage (IRS Rev. Proc. 2025-19). High earners often treat the OOP max as the worst-case insurance scenario to model around. A family earning $200,000 that hits the full $17,000 out-of-pocket maximum would register a Finluxy Healthcare Spend Index of 8.5% for that year — far above the KFF benchmark of 1.2–2.5% for $150k+ households. That catastrophic scenario is why the HDHP is a companion plan, not a standalone strategy. For out-of-pocket healthcare cost at $200k income, the modeling shows that routine-year HSA contributions offset a significant fraction of that tail risk over time.

The HSA Layer: Where the Real Math Shifts

The HSA’s triple tax benefit — pre-tax contributions, tax-free growth, tax-free qualified withdrawals — converts a high-deductible structure from a liability into a long-term asset for households that can fund it fully and rarely draw it down. Effective January 1, 2026, the HSA-DPC pairing became permanently legal under IRS Notice 2026-5, implementing provisions of the One Big Beautiful Bill Act (H.R. 1, enacted July 2025). Before that change, DPC membership disqualified an HDHP enrollee from contributing to an HSA — a structural barrier that made the DPC + HDHP model financially suboptimal for high earners.

The 2026 limits under IRS Rev. Proc. 2025-19: $4,400 for self-only coverage, $8,750 for family coverage, plus a $1,000 catch-up contribution for individuals age 55 or older. One constraint: the DPC monthly fee cannot exceed $150 for an individual or $300 for a family to maintain HSA eligibility under the new rules — a ceiling that comfortably accommodates most DPC practices, given the AAFP 2024 data showing the typical adult retainer runs $50–$100 monthly.

At a 37% marginal federal rate, a family maximizing the $8,750 HSA contribution generates a $3,237.50 immediate tax benefit — real after-tax dollars that reduce the effective net cost of the HDHP + DPC model. Invested at an assumed 7% annual return, that same $8,750 grows to roughly $17,200 over 10 years without additional contributions. For full modeling of that compounding effect, the HSA maximization savings analysis runs the 10-year projection across contribution scenarios.

Annual Math: Three Household Scenarios

Scenario modeling requires fixing assumptions explicitly. The following three cases use 2025 KFF employer premium data, 2026 IRS HDHP and HSA figures, and AAFP 2024 DPC retainer ranges. All figures represent employee cost-sharing only; employer premium contributions are excluded. The tax savings column reflects a 37% federal marginal rate for the DPC + HDHP model — applicable to most households in the $150k–$250k+ range.

Sources: KFF 2025 Employer Health Benefits Survey (premium and worker contribution figures); IRS Revenue Procedure 2025-19 (HSA limits); AAFP 2024 Direct Primary Care Data Brief (DPC retainer range). HDHP/SO employee premium for single coverage estimated from 2024 KFF data showing HDHP/SO premiums average approximately 8% below overall single coverage average. Family HDHP/SO premium estimated proportionally. OOP estimates assume healthy adult(s) with 3–5 primary care encounters and 1–2 specialist visits annually. HSA savings reflect tax deduction only, not investment growth.

Scenario B shows a dramatic net-cost reduction versus the PPO — driven almost entirely by the HSA tax offset against a retainer that covers essentially unlimited primary care. Scenario C’s family numbers are less dramatic because the DPC retainer for two adults ($1,800) is a more significant fixed cost, and because the HDHP deductible exposure scales with family size. That said, a family still saves an estimated $2,000–$4,000 annually in routine years compared to a standard PPO structure, before any HSA investment growth is counted.

Break-Even: When the HDHP’s Downside Erases the Gain

The scenario analysis above models routine years — no hospitalizations, no major procedures, no specialist cascade. The model breaks down when utilization spikes. A family with one surgical event can clear $5,000–$10,000 in out-of-pocket costs in a single year under an HDHP, narrowing or eliminating the premium savings advantage over a PPO.

The relevant break-even is between accumulated HSA assets and catastrophic OOP exposure. At $8,750 contributed annually and 7% growth assumed, an HSA reaches approximately $47,500 in five years (assuming modest annual draws of $2,000 for routine medical expenses). That balance covers roughly 2.8 full OOP-max events under the 2026 family HDHP ceiling of $17,000. In other words, the model becomes self-funding against catastrophic events after roughly five years of disciplined HSA accumulation — a timeline well within reach for a $150k+ household that starts the DPC + HDHP transition in its 30s or 40s.

The HSA-eligible plan vs. PPO net annual cost analysis examines this break-even at lower income thresholds where the margin is tighter. At $150k+, the tax benefit per dollar contributed is large enough that the break-even timeline compresses considerably.

The Overlooked Variable: Specialist Access and Referral Friction

Most cost comparisons between DPC and traditional insurance treat specialist visits as a constant — the same frequency, same cost, regardless of primary care model. The AAFP 2024 DPC Data Brief suggests otherwise. DPC practices carry average patient panels of 600–800 patients versus 2,000–2,500 in traditional fee-for-service settings, enabling the kind of care coordination that reduces unnecessary specialist referrals and duplicate testing. If a DPC physician manages a patient’s hypertension, lipid panel, and thyroid function longitudinally without generating cardiology and endocrinology referrals for each, the specialist cost assumption in the HDHP model needs to be revised downward — potentially significantly.

This is the most underreported variable in the DPC cost literature. Premium comparisons are straightforward arithmetic. But the downstream effect of a physician who actually knows the patient — and has 45 minutes to think through a differential rather than 12 — is captured in reduced specialist visits and avoided diagnostic workups. That variable doesn’t appear in an insurance premium schedule, but it does appear in the annual OOP spend line. For annual healthcare spend benchmarks for $150k+ families, the DPC model’s OOP advantage is likely understated in simple premium comparisons.

Finluxy Healthcare Spend Index

The Finluxy Healthcare Spend Index expresses annual out-of-pocket healthcare spend (excluding premiums) as a percentage of gross household income. The KFF benchmark for $150k+ households is 1.2–2.5% of gross income, per Peterson-KFF Health System Tracker data. The table below applies the index to the three scenarios modeled above, using midpoint OOP estimates and a $200,000 gross household income.

Sources: OOP estimates derived from scenario analysis above (KFF 2025, AAFP 2024, IRS Rev. Proc. 2025-19). KFF benchmark: Peterson-KFF Health System Tracker, household health spending calculator (data through 2022–2023 survey cycles). Index = OOP spend ÷ gross income × 100. DPC retainer included in OOP for Index purposes as it is a direct medical membership payment not covered by insurance.

The single adult in the DPC + HDHP model consistently lands below the KFF benchmark in routine years — a meaningful result given that the benchmark already reflects a relatively low OOP burden for high-income households. The family picture is more volatile: routine years stay within benchmark, but any surgical event pushes the index to 4.0% or above, underscoring why HSA accumulation is the critical buffer in this model. For a fuller picture of how premium healthcare costs ladder across plan types, the employer health insurance employee share analysis covers the full cost structure.

What Changes for the $150k+ Household

At this income level, three factors tip the DPC + HDHP math decisively in the right direction. First, the HSA tax savings are maximized at the 35–37% marginal bracket — a $3,237 annual benefit on the family limit is real money, not a rounding error. Second, $150k+ households can typically absorb the HDHP deductible without financial distress, which means the primary risk of the high-deductible structure — the cash-flow shock of a $3,400+ deductible before insurance engages — is manageable. Third, these households are often overinsuring through employer PPOs without recognizing it: paying for rich first-dollar coverage they rarely use, while foreclosing the HSA contribution that would build long-term healthcare reserves.

The model is not suited for households with chronic conditions requiring frequent specialist care, complex medication regimens, or predictable high utilization — situations where the HDHP deductible fills rapidly and the PPO’s lower coinsurance actually wins on total cost. For those cases, the out-of-pocket maximum reality analysis is more relevant than the DPC + HDHP comparison. Similarly, if the employer’s HDHP offering has a high deductible but weak negotiated rates, the OOP risk under a high-utilization year can dwarf the premium savings. Checking the plan’s negotiated rates — not the posted deductible — is the due-diligence step most household budgeters skip.

For households considering the transition, 2026 marks the first plan year where DPC + HDHP + HSA is fully legally integrated without caveats, per IRS Notice 2026-5. The prior barrier — losing HSA eligibility upon joining a DPC practice — no longer applies, provided the monthly DPC fee stays at or below the $150/month individual or $300/month family cap. That legislative change, quietly enacted in July 2025, materially improves the after-tax math of the DPC model for every HDHP-enrolled household earning enough to fully fund the HSA. A review of mental health coverage gaps and fertility treatment cost gaps shows additional areas where the DPC model’s primary care scope leaves meaningful exposure — context worth factoring before finalizing a plan design. The long-term care insurance cost picture and a check of vision insurance value round out the total household healthcare cost framework that DPC alone does not cover.
