Buying health insurance without an employer means meeting the sticker price your job used to hide — and for 2026 that sticker moved sharply. This article sets out what coverage on your own actually costs: the published benchmark averages, the age curve that multiplies them, the COBRA comparison, and the subsidy arithmetic that decides what most buyers really pay.

The headline number for 2026

Start with the question behind most searches — how much does it cost to buy health insurance on your own? Its nickname form, how much does obamacare cost per month, has the same answer, and so do the paired forms health insurance costs per month and cost of medical insurance per month: the cleanest published yardstick is the benchmark (second-lowest-cost Silver) premium. KFF’s analysis of the 2026 premiums, published in October 2025, put the average benchmark for a 40-year-old in the states using HealthCare.gov at $625 a month, up from $497 in 2025, after insurers raised benchmark premiums by an average of about 26%. That is the unsubsidised price of the yardstick plan — the obamacare insurance cost figure behind the headlines, and the number every other figure in this article hangs off. It is an average across states, not a quote: aca prices are set rating area by rating area, and your local benchmark can sit well above or below it. Healthcare insurance cost headlines that quote one national figure without that warning are selling certainty the market does not contain.

Age: the multiplier nobody escapes

Federal rules price premiums on a fixed age curve (45 CFR 147.102): the same plan costs a 64-year-old up to three times a 21-year-old’s premium. Applying that curve to KFF’s $625 average shows what how much does health insurance cost a month means at different ages — derived figures, shown to display the shape, not quotes for any individual:

This is why obamacare premiums — obama care prices — quoted by a 60-year-old neighbour sound fictional to a 28-year-old: both are telling the truth about the same plan. It is also why the premium tax credit matters more with age — the credit is benchmark minus an income-set contribution, so a bigger benchmark at the same income means a bigger credit, automatically.

COBRA versus the marketplace: the comparison that decides most exits

Leave a job and two doors open. COBRA continues the employer’s plan for typically 18 months — at the full premium, your old share plus the employer’s, plus up to 2% for administration. The marketplace prices the benchmark as above, minus any credit your new, lower income supports. For most households whose income drops with the job, the marketplace wins on premium; COBRA’s case is continuity — same network, deductible progress preserved — and it must be elected within 60 days. Job loss is itself a qualifying life event that opens a 60-day marketplace window, so the two clocks run together. The priced example in the ACA Subsidy Calculator‘s guide — a single person at $30,000 paying $154.99 a month for the benchmark after credit — is the shape of the usual answer.

What people actually pay after the credit

Unsubsidised prices are the exception in the marketplace, not the rule: most enrollees receive the premium tax credit, which caps their benchmark contribution at 2.10%–9.96% of income on the 2026 schedule. KFF’s enrolment data put the average credit at $550 a month per enrollee in HealthCare.gov states in 2025 — the scale of the difference between the sticker and the bill. (That per-enrollee average is also the honest unit behind how much do aca subsidies cost the government: it is the quantity the Congressional Budget Office’s annual scores are built from, enrollee by enrollee.) Measured per household, the affordable care act cost is never the sticker — it is the capped contribution. Your own number is not an average, though: it is your local benchmark minus your contribution, which the ACA Subsidy Calculator — this site’s obama care cost calculator, running the formula openly — computes exactly.

Self-employed: the same market, one extra wrinkle

How much is health insurance for self employed households is the same question with a different income line: your MAGI starts from net self-employment profit, and the premiums you pay can interact with the self-employed health insurance deduction, which lowers the income the credit is measured on. The marketplace does not price freelancers differently — the benchmark and the age curve are the same — but a volatile income makes the estimate-and-reconcile cycle sharper, and since 2026 there is no repayment cap when an estimate proves low. Conservative estimates, updated as the year firms up, are the working rule — and the starting point of any workable plan for healthcare costs.

Hunting the low end honestly

The searches are understandable — low cost health insurance, low cost health insurance for adults, low cost family health insurance, low premium health insurance, health insurance low cost — and the honest map of the low end has three real territories. Bronze plans price below the benchmark (your credit still applies in full, so a subsidised Bronze premium can reach $0). The lowest price health insurance in the regulated market is the catastrophic tier: for the under-30s and exemption holders, with a deductible equal to the $10,600 federal out-of-pocket maximum for 2026. And low cost medical insurance outside the ACA — short-term plans — prices low precisely because it may exclude the conditions you most need covered; low price health insurance that refuses your medical history is cheap the way a lottery ticket is cheap. Compare low cost insurance plans on total exposure — premium plus deductible plus what is actually covered — never on premium alone; that comparison is the whole discipline of low cost insurance health shopping. The levers that genuinely reduce healthcare costs are structural: the credit, the right metal tier for your usage, and in-network care; a fuller treatment of reducing healthcare costs across a household budget starts with getting the subsidy right, which is what the calculator above is for.

One search that isn’t about premiums

What a family benchmark looks like

Benchmarks are per-person prices summed across the family, which produces numbers that startle people used to group-plan thinking. Build one from the KFF average and the federal age curve — a clearly derived illustration, not a quote: two 40-year-old parents at $625 each, plus two children at the child ratio of 0.765, which works out to roughly $374 per child against the 40-year-old’s factor of 1.278. The family’s benchmark is about $1,998 a month before any credit. Against that, a family of four at $65,000 of income owes an expected contribution of $361.84 a month on the 2026 schedule — the credit absorbs the remaining $1,636 or so of the benchmark. Family coverage “costing” two thousand dollars and a family paying three hundred and sixty-two are both true statements about the same plan; the credit is the distance between them.

The metal tiers around the benchmark

The benchmark is a Silver plan, and Silver is defined by actuarial value: on average across a standard population, Bronze plans cover about 60% of costs, Silver 70%, Gold 80% and Platinum 90%. Premiums step up with the share the insurer carries — which is why the unsubsidised price ladder in any rating area runs Bronze, then the Silver benchmark, then Gold and Platinum above it. The credit, however, is fixed by the benchmark: choose Bronze and the same credit stretches across a cheaper premium; choose Gold and you pay the whole difference yourself. And the cost-sharing reductions quietly rewrite Silver’s 70% into 94%, 87% or 73% for eligible incomes — a richer plan than Gold at the benchmark price, available only if you actually select Silver. Tier choice is therefore a real cost decision, not a quality ranking.

A word for the odd search in this cluster — cost of obamacare website. That one is about the troubled 2013 build of HealthCare.gov itself, a political news story from a decade ago. Whatever that website cost the taxpayer then, it changes nothing about any premium in this article now, so it is noted here — honestly, and without a number this page has not verified — and left there.
