Medicare starts at 65. If you retire early, you could have a 20-year gap with no employer coverage and no guarantee any subsidy program will be there. Here is an honest look at what coverage actually costs in 2026, whether the math on paying for it holds up, and what going uninsured really means.
Retire at 45 and you have 20 years before Medicare. At 50, it is 15 years. Most FIRE writing mentions this briefly, says something optimistic about the ACA marketplace, and moves on. That is not enough anymore. Healthcare is frequently the single largest expense in early retirement, and the landscape just got significantly more expensive.
The right starting point is to figure out what full-price coverage actually costs in your state, build that number into your FIRE calculation, and then decide whether to pay it, find a workaround, or genuinely self-insure. All three are real options. None of them are free.
This question gets skipped in most personal finance writing. A lot of healthy people in their 40s look at $1,500 a month in premiums and ask whether it would be smarter to just pay out of pocket and invest the rest. It is a legitimate question with a real answer.
A healthy year without insurance is cheaper than most people expect. A cash-pay primary care visit runs $75 to $200. Generic prescriptions through GoodRx or a Costco pharmacy are $4 to $20 per month. Standard labs through Labcorp's cash-pay portal cost under $100 for most panels. If you are healthy and just need routine care, you might spend $1,000 to $3,000 in a typical year.
The problem is the years that are not typical.
| Scenario | Estimated cash cost (no insurance) |
|---|---|
| Healthy year, routine care only | $500 - $2,000 |
| Urgent care, minor illness or injury | $150 - $400 |
| ER visit, minor (stitches, infection, sprain) | $1,500 - $5,000 |
| Broken bone requiring surgery | $15,000 - $40,000 |
| Appendectomy | $20,000 - $50,000 |
| Heart attack, hospitalization | $50,000 - $150,000 |
| Cancer treatment (varies widely by type) | $100,000 - $500,000+ |
| Childbirth (natural, no complications) | $10,000 - $30,000 |
One thing that surprises people: cash-paying patients often negotiate meaningful discounts. Hospitals set inflated list prices and negotiate them down with insurers. Cash patients can often do the same directly, sometimes getting 40 to 60 percent off billed rates, particularly for planned or non-emergency procedures. The true cost of a major bill is usually less than the sticker price, though it is still significant.
Before deciding insurance is the safe choice, it is worth being honest about how it actually works. Paying premiums does not mean claims get paid.
According to KFF's 2024 analysis of ACA marketplace data, insurers on HealthCare.gov denied 19% of in-network claims that year, nearly 1 in 5. The range by insurer runs from 3% to 36%, and in 2023 some insurers denied more than half of all claims.
Of the roughly 85 million claims denied in 2024, fewer than 1% of patients appealed. Of those who did appeal, insurers upheld the denial 66% of the time. That means the people who fought back won about a third of the time. Most people never try.
Prior authorization is where the worst outcomes happen. Insurers require pre-approval for many treatments and surgeries before they will pay, a process that can drag on for weeks. According to a 2024 AMA physician survey, 24% of doctors reported that prior authorization delays led to a serious adverse event for a patient, including hospitalization, permanent impairment, or death. 93% said it delays care. 78% said patients abandon treatment entirely because of the process.
The out-of-pocket maximum is the real protection insurance provides: once you hit it, the insurer must legally cover the rest of approved claims for the year. But "approved" is doing a lot of work in that sentence. You are not buying a guarantee your cancer treatment gets paid. You are buying a legal right to fight for it.
According to CMS's 2026 marketplace data, the national average bronze plan for a 60-year-old now runs $969 per month with no subsidy, after the 26% premium increase this year. Younger ages pay less, but the costs scale up quickly. Here is what it looks like across retirement ages, annually.
2026 unsubsidized bronze plan annual premiums. Anchored to CMS national average of $969/month for age 60. State variation is large: the same plan runs $601/month in Maryland and $1,667/month in Wyoming.
Now look at what happens when you run those numbers over a 20-year retirement. A couple paying $1,500/month in premiums spends $360,000 over 20 years. If they had invested that money at a 7% real return instead, it would grow to roughly $780,000. Their average expected medical spending if healthy and uninsured, based on Peterson-KFF out-of-pocket data, would be around $3,000 per year, or $60,000 total over 20 years.
Couple paying $1,500/month in premiums vs. investing those premiums at 7% real return vs. estimated out-of-pocket medical costs if uninsured and healthy ($3,000/year). Assumes no major medical events.
If you stay healthy for 20 years, you would have come out roughly $700,000 ahead by self-insuring and investing those premiums rather than paying them to an insurer. That is the uncomfortable math that does not fit neatly into "always buy insurance."
So why does anyone pay for coverage? Because of the years that are not healthy. A cancer diagnosis increases average annual medical spending by more than three times, and treatment can run $100,000 to $500,000 without coverage. According to the American Cancer Society, about 39% of Americans will be diagnosed with cancer at some point in their lifetime. A meaningful share of those diagnoses happen between ages 45 and 65. Insurance is not a hedge against routine costs. It is a hedge against that specific, expensive outcome.
Whether self-insuring makes sense depends almost entirely on how large your portfolio is relative to a worst-case medical event. A $200,000 medical bill means something very different depending on where you are financially.
| Portfolio size | $200k event | Verdict |
|---|---|---|
| $500,000 | 40% of portfolio | Do not self-insure |
| $1,000,000 | 20% of portfolio | Risky |
| $1,500,000 | 13% of portfolio | Borderline |
| $2,000,000 | 10% of portfolio | Defensible |
| $3,000,000+ | Under 7% | Real option |
A $200,000 medical event as a percentage of portfolio at different sizes. Assumes event happens in year one of retirement with no recovery time.
The other factor is health history. Self-insuring when you are 45, healthy, and have no family history of major illness is a very different bet than self-insuring with a chronic condition or a family history of cancer. This is not a one-size-fits-all calculation.
A middle path a lot of FIRE people end up using: a Direct Primary Care membership for routine care, plus either a catastrophic-only plan or a genuine cash reserve for major events, rather than a full comprehensive plan. You give up the out-of-pocket maximum protection but avoid paying $15,000 to $20,000 per year in premiums you will likely rarely use.
If paying $15,000 to $25,000 per year in unsubsidized premiums is not workable, here are the legitimate alternatives.
Part-time work for benefits. Certain employers offer health coverage to part-time employees working around 20 hours per week. Starbucks is the most cited example. Trader Joe's, Costco, and REI have similar policies. A 20-hour-per-week job that covers a family's health insurance changes the entire equation. You are not working for the money. You are working for the one benefit that is otherwise $18,000 a year. This is the Barista FIRE strategy applied specifically to healthcare.
Spouse on employer coverage. If your partner continues working and has access to employer-sponsored insurance, being added as a dependent is often the cheapest option available. Employer plans are heavily subsidized by the company. This keeps one person tied to employment, which some couples see as a reasonable hedge and others see as a constraint. It is a real path either way.
Health sharing ministries. These are not insurance. Members pool money to cover each other's medical costs. Monthly contributions are typically $300 to $600 for a couple, significantly less than unsubsidized premiums. They are unregulated, can decline coverage for pre-existing conditions, and several have collapsed in recent years. Worth researching seriously if cost is the binding constraint and you are healthy, but read the full guidelines document before signing up.
Whatever strategy you end up using, if you have access to a high-deductible health plan through an employer right now, max your HSA every year until you retire. The HSA is the best tax-advantaged account available: contributions come out pre-tax, money grows tax-free, and qualified medical withdrawals are also tax-free.
The 2025 limit is $4,300 for individuals and $8,550 for families, with a $1,000 catch-up at age 55. Invest the balance in index funds rather than leaving it in cash and it compounds into a dedicated medical reserve. You cannot contribute new money once you leave employer coverage, so the time to build it is now. Learn more in the HSA retirement guide.
Honestly, I think health insurance in the US is a pretty sketchy product. Premiums have gone up significantly since the ACA subsidies expired. Insurers deny nearly 1 in 5 claims. Prior authorization delays cause real harm. And the whole system proved in 2026 that the rules can change under your feet at any time. That is a lot to trust and pay for simultaneously.
My honest view is that whether you buy insurance should depend on what premiums actually look like when you retire, in your specific state, at your specific age. There is no universal right answer. But one thing is true regardless: a large portfolio gives you optionality that a small portfolio does not. If you retire with $2 million or more, going uninsured is a real and financially defensible choice. You are self-insuring, not gambling. If you are Lean FIRE with a smaller number and a catastrophic event could genuinely derail your retirement, that optionality is not there yet and coverage probably makes sense even if the product is frustrating.
Building toward a large enough portfolio that going uninsured is a real option is, in my opinion, one of the underrated reasons to aim higher than your minimum FIRE number. Healthcare freedom is another form of financial freedom.
