TL;DR — Quick Verdict
- Short-term plan premiums typically run $100–$400 per month for a healthy adult — often 50–80% cheaper than an unsubsidized ACA plan, per HSA for America and KFF pricing data.
- The catch is exclusions: a 2025 KFF analysis found 98% of short-term products exclude maternity care, 48% exclude outpatient prescription drugs, and 40% exclude mental health services.
- Short-term plans carry no federal out-of-pocket cap; ACA plans cap 2026 in-network cost-sharing at $10,600 for an individual (CMS). One serious hospitalization can erase years of premium savings.
- Comparison result: for a healthy person bridging a 2–4 month gap, short-term wins on price; for anyone with a chronic condition, pregnancy plans, or maintenance drugs, an ACA plan is the cheaper true cost.
- Recommendation: treat a short-term plan as accident-and-emergency insurance only, and price it against a subsidized marketplace plan before you buy.
A three-month short-term policy advertised at $70 a month can quietly become a $100-plus monthly bill once application and administrative fees are stacked on top — a markup the ACA Marketplace legally cannot charge, according to a November 2025 KFF analysis. That gap between the sticker premium and the real cost is the entire story of short-term limited-duration insurance (STLDI). These plans, sold by carriers such as UnitedHealthcare’s Golden Rule and marketed through eHealth and Agile Health Insurance, exist to fill temporary coverage gaps — between jobs, after aging off a parent’s plan, or while waiting for a new employer’s benefits to start. They are cheap for a reason: they can deny you, drop you, and exclude the exact care you end up needing. This article breaks down what short-term plans actually cover, the specific exclusions that catch buyers off guard, the real 2026 cost math against an ACA plan, and the narrow set of people for whom the trade-off makes sense.
What a Short-Term Health Plan Actually Costs in 2026
Premium is where short-term plans win, and it is the only category where they consistently do. A healthy adult can expect monthly premiums roughly in the $100–$400 range depending on age, state, and the deductible chosen, with some healthy young buyers finding policies under $100. That undercuts the unsubsidized ACA benchmark — a figure KFF put at $497 per month for a 40-year-old on the second-lowest-cost Silver plan in 2025, rising toward a $625 average benchmark in 2026.
The premium is not the number that matters, though. Short-term plans layer on costs that comprehensive plans cannot. Understanding how a plan’s deductible and out-of-pocket maximum mechanics interact is the difference between a plan that protects you and one that only looks cheap.

Note the out-of-pocket maximum row. That single line is where the math turns. A short-term plan with no cap means a serious accident can generate unlimited cost-sharing, wiping out every dollar of premium savings in one hospital stay.
The Exclusions That Catch Buyers Off Guard
Short-term plans are exempt from the ACA’s essential health benefit rules, which means they legally omit entire categories of care. KFF reviewed the actual products sold on eHealth and Agile Health Insurance in 2025 and quantified exactly how often each benefit disappears.
Among the short-term products KFF examined, 98% excluded maternity care, 94% excluded adult immunizations, 48% excluded outpatient prescription drugs, and 40% excluded mental health services and substance-use treatment each. Where drug coverage exists at all, it is frequently capped at $1,000 to $5,000 per policy term — often too little to cover a single specialty medication.

Beyond category exclusions, the fine print gets creative. KFF documented plans that refuse to cover hospital stays if the enrollee is admitted on a Friday or Saturday, and others that deny care for injuries tied to certain recreational sports. Pre-existing conditions — diabetes, obesity, depression, anxiety — can be grounds for outright denial or post-claim exclusion. Anyone managing an ongoing diagnosis should read the guidance on plan selection with a chronic condition before assuming a cheap premium is a bargain.
How Post-Claims Underwriting Works — and Why It Matters
Medical underwriting is the mechanism that makes short-term premiums cheap, and post-claims underwriting is the mechanism that makes them risky. Here is the real-world sequence. You apply, answer a health questionnaire, and get approved in 24 to 48 hours. You pay premiums for two months. Then you are hospitalized for chest pain, and you file a claim.
At that point the insurer reviews your full medical history — not before issuing the policy, but after you file. If it finds any record suggesting the condition existed before coverage began, even an undiagnosed abnormality in an old chart, it can classify the claim as a pre-existing condition and deny payment. A 2025 HHS review cited by industry analysts found that more than half of sampled short-term plans contained exclusions broad enough that conditions like asthma, diabetes, or heart symptoms could be denied on this basis.
This is structurally different from an ACA plan, which must accept you and cannot investigate your history to deny a claim. The cost of that difference only appears when you are sick — the worst possible moment to discover your coverage is thinner than the premium implied. Understanding the prior authorization and denial response process becomes far more important on a plan built to scrutinize claims.
Short-Term vs. ACA Marketplace: Which Is Better for a Coverage Gap?
Run the numbers on a healthy 30-year-old bridging a four-month gap between jobs. A short-term plan at $200 per month costs $800 over four months. A subsidized ACA plan, depending on income, might cost less than that after premium tax credits — and it covers the drugs, mental health visits, and maternity care a short-term plan strips out. For many people, the “cheap” short-term option is not even cheaper once subsidies are applied, which is why checking ACA marketplace subsidy eligibility and savings should come first.
The comparison flips only for a specific buyer: someone who earns too much for subsidies, is healthy, needs coverage for a genuinely short window, and can absorb the risk of an uncapped bill. For people who lost job-based coverage, the choice usually sits between a short-term plan and continuation coverage — the trade-offs are laid out in this COBRA vs. marketplace coverage comparison. And because losing coverage triggers a special enrollment window, most job-loss situations do not require a short-term plan at all.
Verdict
For a healthy person who does not qualify for subsidies and needs coverage for one to four months, a short-term plan is the lower-cost option and a reasonable accident-and-emergency backstop. For everyone else — anyone subsidy-eligible, anyone with a chronic condition, anyone who might need maternity, mental health, or maintenance-drug coverage — an ACA Marketplace plan is the cheaper true cost despite the higher premium, because the short-term plan’s exclusions and uncapped exposure convert into out-of-pocket bills exactly when you can least afford them.
What Most People Get Wrong About Short-Term Plans
Three mistakes account for most of the regret buyers report after the fact.
Mistake one: treating the premium as the total cost. The consequence is a shattered budget when an uncapped bill lands. The correct action is to add the deductible, the coinsurance, and any application fees to the premium, then compare that full figure — not the sticker price — against an ACA plan, using the framework in comparing plans beyond the monthly premium.
Mistake two: assuming a short-term plan covers prescriptions. The consequence is paying full retail for maintenance medication, or discovering a $1,000 term cap is exhausted by March. The correct action is to confirm drug coverage and its cap in writing before enrolling, since nearly half of products exclude outpatient drugs entirely.
Mistake three: buying a short-term plan after a job loss without checking marketplace options. Losing coverage opens a special enrollment period, so the correct action is to price a subsidized ACA plan first — a step that also protects people considering health coverage options for the self-employed, who often assume short-term is their only affordable route.
A fourth trap is geographic: several states have banned or heavily restricted these plans, so a policy advertised online may not even be legal where you live.
Who Should Actually Buy One — and Where They’re Banned
The honest answer to “is it worth it?” is conditional. A short-term plan makes sense if you are healthy, need coverage for a defined short period, do not qualify for ACA subsidies, take no regular medications, and understand you are buying protection against catastrophic accidents rather than comprehensive care. If any one of those conditions fails, the math tilts toward a marketplace plan.
Geography narrows the field further. The 2024 federal rule capped new short-term policies at a three-month initial term and a four-month total duration (CMS, effective September 1, 2024). Federal regulators announced in August 2025 that they would not prioritize enforcement of that 2024 definition pending future rulemaking, which means state law is now the practical governing standard — and states set stricter limits or outright bans. Illinois banned short-term plans effective January 2025, and several other states plus the District of Columbia do not permit them at all, per GoodRx and KFF tracking. Before buying, confirm availability with your state department of insurance.
Early retirees under 65 are a group frequently steered toward short-term plans, usually mistakenly; the more durable options are covered in this guide to coverage options for early retirees under 65. And anyone whose income might qualify them for public coverage should first check state Medicaid expansion eligibility, which costs far less than any short-term premium.
Frequently Asked Questions
How long can a short-term health plan last in 2026?
Under the 2024 federal rule, new short-term policies are limited to a three-month initial term and four months total including renewals (CMS, effective September 1, 2024). Federal agencies deprioritized enforcement of that definition in August 2025, so your actual limit depends on your state — some allow longer durations, while states like Illinois ban the plans entirely as of January 2025.
Do short-term plans cover pre-existing conditions?
Generally no. Short-term plans are medically underwritten, meaning insurers can deny your application, charge more, or exclude a condition based on your health history. They can also apply post-claims underwriting — reviewing your records after you file a claim to deny it as pre-existing. KFF documents that plans routinely deny coverage for diabetes, obesity, depression, and anxiety.
Is a short-term plan cheaper than an ACA plan?
On premium alone, usually yes — often 50–80% less, with monthly costs frequently in the $100–$400 range. But if you qualify for ACA subsidies, the marketplace plan can cost less after tax credits while covering far more. The short-term plan also carries no federal out-of-pocket cap, unlike the ACA’s $10,600 individual limit for 2026 (CMS), so its true cost in a bad year can be much higher.
How We Researched This Article
This analysis draws on primary federal and institutional sources for every regulatory and cost figure. Coverage exclusion percentages — 98% for maternity, 48% for outpatient prescription drugs, and 40% each for mental health and substance-use services — come directly from KFF’s November 2025 review of short-term products actually sold on eHealth and Agile Health Insurance, the most current product-level dataset available (KFF short-term plan analysis). Federal duration rules and their August 2025 enforcement status were verified against the CMS fact sheet and the joint DOL, HHS, and Treasury statement. The 2026 out-of-pocket maximum of $10,600 for individual coverage was confirmed through HealthCare.gov and CMS cost-sharing guidance.
Premium ranges are modeled, not measured: short-term pricing varies by carrier, age, state, and deductible, so the $100–$400 figure represents a defensible range aggregated from KFF pricing observations and industry brokers rather than a single national average, which no federal agency publishes for short-term products. ACA benchmark premiums are measured figures drawn from KFF’s marketplace analysis. Where sources reported different figures, we used the most recent primary source and labeled its data year inline. Limitations include the absence of a comprehensive federal short-term pricing database and state-by-state variation that a national article cannot fully capture; readers should confirm local availability and pricing with their state department of insurance. This research was last conducted in July 2026. All figures were verified against named primary sources before publication.
