COBRA vs Marketplace Insurance: Which Costs Less When You Lose Your Job

Fact-checked by the Smart Insurance 101 editorial team

When you lose your job, the question of COBRA vs marketplace insurance stops being theoretical. Suddenly you’re looking at a COBRA notice that demands over $792 a month to keep your existing plan, or an invitation to shop the Health Insurance Marketplace, where the same person might get coverage for under $100 a month after subsidies. That gap is real, but the choice isn’t just about the premium sticker. The right call depends on your income, your health, and what you’d have to give up by switching.

In 2026, the math has shifted again. Enhanced premium subsidies that made Marketplace plans extraordinarily cheap for millions of people expired at the end of 2025, reverting the subsidy formula to its pre-2021 structure. Employer health costs have continued their steady climb, with the average single-coverage premium hitting $9,325 a year in 2025, according to the Kaiser Family Foundation’s Employer Health Benefits Survey. For families, that number was $26,993. All of that cost becomes your responsibility under COBRA, plus a 2% administrative fee. But the Marketplace, even without the enhanced subsidies, still offers premium tax credits that cap what you pay based on your income.

What follows draws on federal data from the U.S. Department of Labor, the Centers for Medicare & Medicaid Services, and KFF premium analyses, plus a close reading of how tax rules, HSA eligibility, and state variation tilt the decision. We’ve also included a step‑by‑step action plan built from the contours that most comparison guides miss.

What Happens to Your Health Coverage When You Lose Your Job

COBRA coverage is not automatic: it’s a continuation option. Under federal law, you have 60 days from the date you receive your COBRA election notice to decide whether to keep your group health plan, and you get another 60-day special enrollment period to buy a Marketplace plan from the date you lose job‑based coverage. Those windows can overlap, which is why the smart move is to price both options promptly, not default to one.

The Department of Labor makes it explicit: you can apply for Marketplace coverage even if you are eligible for COBRA, and you are not required to take COBRA first. In fact, HealthCare.gov advises that you weigh the cost of COBRA against Marketplace plans before deciding, because if you enroll in COBRA and later want to switch, you generally can’t move to a Marketplace plan until the next Open Enrollment, unless you wait for COBRA to end and trigger another special enrollment period. The fine print on timing matters.

How Much Does COBRA Actually Cost in 2026

COBRA premiums equal the full cost of the plan, the portion your employer previously paid plus your share, plus an administrative fee of up to 2%. Using KFF’s 2025 employer health benefit averages, that puts the monthly COBRA premium for a single person around $792 (from a $9,325 annual premium, divided by 12 and multiplied by 1.02). For family coverage, the monthly number jumps to roughly $2,294. These are not abstract estimates; they reflect what a worker with an average employer plan would see on a COBRA notice.

No subsidy exists for COBRA. Your income doesn’t matter; if you’re eligible, you pay the full freight. That creates an immediate asymmetry with the Marketplace, where premium tax credits can reduce what you pay to a fraction of the benchmark premium. The contrast is starkest for people with incomes below 400% of the federal poverty level, roughly $60,240 for a single person in 2026, but even those above that threshold often find Marketplace unsubsidized premiums lower than COBRA for comparable plans.

One scenario where COBRA can make sense despite the high premium: you’ve already met a large deductible or out‑of‑pocket maximum for the year. If it’s September and you’ve hit your $3,000 deductible, paying a few months of COBRA at $792 each, $2,376 total, might be cheaper than starting a new Marketplace plan, resetting the deductible, and facing fresh out‑of‑pocket costs before the year ends. The calculation changes once you factor in the timing of medical expenses. Later, we’ll break this down with a worked example that shows the crossover point.

Marketplace Premiums and Subsidies After the Enhanced Credits Expired

In 2026 the national average lowest‑cost silver Marketplace premium for a 40‑year‑old is $611 per month, according to KFF’s state‑by‑state premium tracker. That’s before subsidies, and it reflects double‑digit percentage increases from 2025, roughly 18% on average across many states, as insurers adjusted to the end of the enhanced premium tax credits. Those enhanced credits, which capped what no individual paid at 8.5% of income regardless of income level, expired on December 31, 2025. The original Affordable Care Act subsidy formula is back.

Under that formula, premium tax credits are tied to the second‑lowest‑cost silver plan in your area and lock your required contribution to a percentage of your Modified Adjusted Gross Income (MAGI). For example, a single person earning $30,000, about 200% of the federal poverty level, would pay 6.52% of income toward that benchmark plan, or $1,956 per year. That’s $163 per month. The rest of the $611 premium is covered by the subsidy. Contrast that with the average COBRA premium of $792: the Marketplace plan saves this person over $600 every month.

At $60,000 (roughly 400% FPL), the required contribution rises to 9.83% of income, capping the monthly premium at about $492. That still beats COBRA’s $792. Someone at 401% FPL gets no subsidy at all in most states, which means they’d pay the full $611. In that narrow band, the Marketplace unsubsidized premium is about $180 less than COBRA each month, so Marketplace wins on premium alone. The only groups for whom the math tilts the other way are those who don’t qualify for a subsidy and have an employer plan whose total premium falls below the benchmark silver premium, a small slice, but real in some lower‑cost regions.

Direct Cost Comparison: COBRA vs Marketplace by Scenario

To put the numbers side by side, we modeled a 40‑year‑old single non‑smoker in a county where the benchmark silver plan costs the national average of $611. The table below shows the monthly premium for COBRA versus Marketplace at three income levels, using the post‑enhanced‑subsidy rules. The COBRA premium ($792) is a constant; the Marketplace premium drops sharply as income falls.

The $45,000 example uses the ACA’s sliding scale: at about 300% FPL the contribution is around 8.6% of income, which comes to $3,870 per year, or roughly $325 per month. Even with the original subsidy scales back in place, the Marketplace undercuts COBRA for every income level shown, and the advantage grows dramatically for lower earners. A household of two, with combined income of $55,000, can expect similar proportional savings, though the premiums are higher in absolute dollars.

This is a pure premium comparison. It doesn’t account for the fact that deductibles and out‑of‑pocket maximums often reset when you switch plans, a reality that can erase the premium savings if you have a lot of medical expenses lined up in the remaining months of the year. That’s where the analysis gets personal.

Provider Networks, Benefits, and Continuity Trade‑offs

Money aside, the biggest thing you keep with COBRA is your current network. Same doctors, same hospital system, same drug formulary. With a Marketplace plan, especially a narrow‑network silver or bronze product, you may need to change providers. For someone managing a chronic condition or mid‑treatment, that disruption carries a cost that doesn’t show up on a premium statement.

COBRA also preserves your accumulated deductible and out‑of‑pocket spending for the plan year. If you’ve already spent $2,000 toward your $3,000 deductible, switching to a Marketplace plan throws away that progress. That’s the scenario where COBRA can be the financially smarter move even at a higher monthly premium. The calculation: keep COBRA for the final 4 months of the year, pay $3,168 in premiums (4 × $792), and have a small amount left on your max‑out‑of‑pocket, versus resetting the clock, paying a lower monthly premium of $163 but potentially thousands in new deductibles before the insurer pays a dime.

COBRA is not inherently a comprehensive safety net for benefits like dental and vision, which we address next. And the guarantee of no pre‑existing condition exclusions applies equally to Marketplace plans; the ACA prohibits them. The real “pre‑existing” problem is network, not coverage legality.

The Hidden Cost Differences: Taxes, HSAs, and State Mini‑COBRA Rules

The financial picture gets more complex once you look past the monthly premium. COBRA premiums are paid with after‑tax dollars. While you can deduct health insurance premiums on Schedule A if you itemize and your total medical expenses exceed 7.5% of adjusted gross income (AGI), most recently unemployed individuals don’t itemize. The effective cost of COBRA is what you pay, unreduced by any government offset. In contrast, Marketplace premium tax credits are advanced by the government directly to your insurer based on your estimated income. At tax time, the Internal Revenue Service reconciles those credits against what you actually earned. If you underestimated your income, you may have to repay some of the subsidy. The IRS caps the repayment amount for people under 400% FPL, but it can still run into the thousands of dollars.

It’s worth thinking through the income‑estimation problem carefully. A person who takes on freelance work after a layoff, or picks up unemployment benefits that count as taxable income, can easily land higher than expected. Financial tools from companies like TurboTax or H&R Block can help model projected MAGI mid‑year, but the subsidy repayment risk is real and rarely flagged at enrollment. The Consumer Financial Protection Bureau (CFPB) has published guidance on how tax credit reconciliation works, and it’s worth reading before you accept an advanced credit estimate.

Health Savings Accounts add another layer. If your employer plan was a qualified high‑deductible health plan (HDHP) and you had an HSA, you can continue contributing to that HSA as long as you remain enrolled in an HDHP through COBRA. The moment you switch to a Marketplace plan that is not HDHP‑eligible, you lose the ability to make pre‑tax HSA contributions. That could mean forfeiting up to $4,150 for an individual (2026 IRS limit) in tax‑advantaged savings. For a family, the HSA contribution limit is $8,300. That’s a hidden benefit that vanishes the instant you leave the HDHP world. Many people would be better off paying a higher COBRA premium if it lets them keep maxing the HSA and preserving the triple tax benefit, especially if they’re in a high marginal tax bracket. This trade‑off gets overlooked in almost every comparison.

The picture also shifts depending on your state. Approximately 40 states have mini‑COBRA laws that require insurers to offer continuation coverage to employees of businesses with fewer than 20 workers, the federal COBRA threshold. These laws can extend coverage for 3 to 12 months beyond federal COBRA, giving small‑business employees more runway. Rules differ by state; in California, for instance, Cal‑COBRA can extend coverage for up to 36 months. In New York, state law offers its own continuation rules that can apply even when federal COBRA doesn’t. If you worked for a small firm, your option set may be broader than the federal notice suggests.

Dental, Vision, and Dependents: What Gets Left Out of Standard Comparisons

Most discussions of COBRA vs marketplace insurance ignore dental and vision coverage entirely. Under COBRA, if your employer plan included dental and vision benefits, you can continue those as well, often on the same election form. Marketplace plans, however, treat dental as a standalone product. You must buy a separate dental plan or a health plan with embedded pediatric dental, but adult dental is not guaranteed. Vision coverage is typically not included at all. For a family that needs orthodontia or routine eye exams, the absence of these benefits can add hundreds of dollars a month in out‑of‑pocket expenses on the Marketplace side, narrowing the real cost gap.

Dependents create additional wrinkles. A divorced spouse who was covered under your plan is a qualified beneficiary under COBRA and can elect continuation coverage independently, even if you don’t. The Marketplace, however, does not cover an ex‑spouse who is not a tax dependent. Similarly, a child who leaves college and ages off a parent’s plan at 26 can get COBRA continuation for up to 36 months, while Marketplace options for that young adult may be limited to catastrophic plans or full‑price bronze plans if they have modest income but are not eligible for Medicaid. The interaction of self‑employed health options with dependent coverage is another topic few articles address, but it’s directly relevant when a spouse is picking up freelance work after a layoff.

Your 8‑Step Action Plan to Choose Between COBRA and Marketplace Insurance

This is not the time to guess. The decision has a hard deadline and real financial consequences. Here is a concrete checklist, grounded in the federal eligibility rules and the cost data we’ve just walked through.

1. Open the COBRA election notice immediately. Note the total monthly premium (the full plan cost + the 2% fee) and the deadline date, it’s exactly 60 days from receipt.
2. Download your Summary of Benefits and Coverage from your employer plan. You’ll need your current deductible, out‑of‑pocket maximum, and how much you’ve already spent toward them this year.
3. Visit HealthCare.gov or your state’s exchange within 60 days of your coverage loss. Enter your household income estimate for the rest of the year, your county, and your family size. The system will display premiums for available plans after subsidies.
4. Do the premium math side‑by‑side. Write down the COBRA monthly premium, the Marketplace silver benchmark premium (after subsidy), and also look at a high‑deductible plan if you have an HSA you want to preserve.
5. Estimate the deductible reset cost. If you are mid‑year and have already met a chunk of your deductible, multiply the remaining months of COBRA premiums and compare that total to the Marketplace premium(s) for the same period plus the new plan’s deductible you’d likely pay.
6. Check your HSA status. If you’re on an HDHP via COBRA, determine how much pre‑tax HSA contribution room you’d lose by switching. The IRS sets the 2026 individual limit at $4,150; factor that dollar amount into the annual cost difference.
7. Look up your state’s mini‑COBRA rules. If you worked for a company with fewer than 20 employees, see if your state extends continuation coverage past federal COBRA. California’s Cal‑COBRA, New York’s continuation rules, and similar state programs can buy extra months to land a new job with insurance.
8. Set a calendar reminder for the election deadline. If you miss it, COBRA is gone. And once you choose COBRA, know that you generally cannot switch to Marketplace until Open Enrollment unless you exhaust COBRA or have another qualifying life event.

What This Means for You

The numbers make one thing clear: for most people who lose job‑based coverage in 2026, the Marketplace comes out ahead on premiums, often by a lot. The expiration of enhanced subsidies hasn’t changed that fundamental dynamic. A single person at average income can still pay less than $200 a month after subsidies versus close to $800 under COBRA. But the decision isn’t just about the sticker price.

If you’re mid‑way through a plan year and have already met a large deductible, the premium savings from the Marketplace can evaporate when you reset that clock. In that case, a short COBRA bridge may cost you more in monthly payments but far less in total healthcare spending. If you have an HSA, the tax‑advantaged contributions you’d lose by leaving an HDHP, up to $4,150 for an individual per IRS rules, can outweigh the premium difference, especially if you’re in a higher tax bracket. And if keeping your current specialists or maintaining seamless cancer care matters, the network continuity of COBRA is not something a subsidy calculator can price.

Your next move should be to run both numbers exactly: the COBRA notice premium multiplied by the months you need coverage, versus the post‑subsidy Marketplace premium plus a realistic estimate of the deductible you’ll incur in a new plan. Then layer on the HSA factor, the network question, and any state mini‑COBRA extension that gives you extra time. The formula is personal, but the data laid out here gives you the raw inputs to solve it.

Frequently Asked Questions

What is the deadline to decide between COBRA and Marketplace insurance after losing my job?

You have 60 days from the date you receive your COBRA election notice to sign up, and a separate 60‑day special enrollment period from the date you lose job‑based coverage to apply for a Marketplace plan. The deadlines can run simultaneously, so you must price both options within that window.

Can I get a subsidy on COBRA premiums?

No. COBRA premiums are not eligible for any government subsidy, no matter your income. You pay the full employer plan cost plus up to a 2% administrative fee.

How does my 2026 income affect Marketplace premium tax credits?

Premium tax credits are based on your projected annual income for the coverage year. For 2026 the credits follow the original ACA formula: your required contribution is a percentage of your Modified Adjusted Gross Income (MAGI) that rises as you approach 400% of the federal poverty level. If your actual income ends up higher than you estimated, the IRS may require repayment of some of the advanced credit at tax time.

Does COBRA let me keep my health savings account (HSA)?

Yes, if your COBRA plan is a qualified high‑deductible health plan (HDHP). You can continue making pre‑tax HSA contributions up to the IRS annual limit. If you switch to a Marketplace plan that is not HDHP‑eligible, you lose your HSA contribution eligibility for that year.

What are mini‑COBRA laws and do they apply to me?

Mini‑COBRA laws are state‑level continuation coverage requirements for employees of small businesses (fewer than 20 workers) that are not covered by federal COBRA. They can extend coverage for 3 to 36 months depending on the state. Check your state’s insurance department website to see if you have extra continuation rights beyond federal COBRA.

Will I lose my dental and vision benefits if I switch from COBRA to a Marketplace plan?

Possibly. COBRA can continue your employer’s dental and vision coverage exactly as before. Marketplace health plans generally do not include adult dental or vision; you would need to buy a separate standalone dental plan with different coverage limits. Vision coverage is often not available at all.

If I have already met my deductible this year, should I stay on COBRA?

Often yes. If you’ve already spent thousands toward your annual deductible and out‑of‑pocket maximum, switching to a Marketplace plan resets those amounts to zero. Paying a few months of higher COBRA premiums can be cheaper than starting over with a new plan and absorbing fresh out‑of‑pocket costs.
