All premium and contribution figures reflect 2025 KFF employer-plan data and 2026 Marketplace rate filings, the most recent verified figures at publication; subsidy rules are in flux pending Senate action on the enhanced premium tax credit.
TL;DR — Quick Verdict
- COBRA lets you keep your exact employer plan but charges up to 102% of the full premium — that’s the $9,325 single or $26,993 family average annual cost (KFF 2025), plus a 2% administrative fee your employer previously absorbed most of.
- A Marketplace plan can be far cheaper if you qualify for a premium tax credit, but 2026 benchmark premiums rose 21.7% (Urban Institute) and the enhanced credits expired December 31, 2025.
- Comparison result: For a subsidy-eligible single person under roughly $62,750 income, the Marketplace almost always wins on monthly cost; for someone mid-deductible with ongoing treatment, COBRA’s continuity often wins.
- You get one 60-day window to choose — and electing COBRA does not forfeit your Marketplace special enrollment period if you act inside those 60 days.
- Run both numbers on HealthCare.gov before your 60 days lapse; the “right” answer flips entirely on your income and whether you’ve already met your deductible.
Losing job-based coverage forces a decision most people make in a fog, right when a paycheck just disappeared. The math is unforgiving: employer-sponsored family coverage averaged $26,993 per year in 2025, and workers themselves paid only $6,850 of that, according to the KFF Employer Health Benefits Survey. COBRA hands you the other $20,143 your employer used to cover — plus a 2% surcharge. Meanwhile, Marketplace shoppers face a different shock: benchmark premiums climbed 21.7% for 2026 per the Urban Institute, and the enhanced subsidies that made exchange plans cheap for millions lapsed at the end of 2025.
This comparison breaks down what COBRA and Marketplace coverage each actually cost in 2026, who saves money under which option, and the three timing mistakes that quietly cost people thousands. We’ll model real scenarios using KFF and CMS figures, not vague averages — because the decision hinges on numbers specific to your income, your deductible progress, and your ZIP code.
What COBRA Actually Costs in 2026
COBRA continuation coverage isn’t a discount program — it’s the right to keep paying for the exact plan you had, at its full unsubsidized price. Federal law caps what you can be charged at 102% of the total premium: 100% for the coverage itself plus a 2% administrative fee, per U.S. Department of Labor rules. During disability extensions (months 19 through 29), that cap rises to 150%.
The sticker shock comes from a number most employees never see. Your employer paid roughly 84% of your single premium and 74% of your family premium while you worked there. Strip that subsidy away and the true cost surfaces. For a deeper look at how employers price their side of the ledger, see our breakdown of small business health coverage costs across plan types and the tax treatment of employer health contributions.
COBRA cost = total premium × 1.02 (102% cap). Premium source: KFF 2025 Employer Health Benefits Survey. Monthly figures rounded to the nearest dollar.
Those monthly numbers explain why COBRA feels punishing. A family paying $2,294 a month is covering what their employer quietly financed for years. The plan didn’t get more expensive — the subsidy vanished.
What Marketplace Coverage Costs After the 2026 Subsidy Shift
Marketplace pricing works on two levels: the gross premium (the plan’s list price) and the net premium (what you pay after a tax credit). For 2026, both moved against buyers. The Urban Institute found benchmark silver premiums rose an average of 21.7% — far steeper than the 6% employer-plan increase. On top of that, the enhanced premium tax credits from the American Rescue Plan and Inflation Reduction Act expired December 31, 2025.
The expiration reshapes the entire calculation. KFF estimates subsidized enrollees will pay 114% more on average in net premiums — roughly $1,016 more per year — with the original ACA subsidy structure snapping back into place: a hard income cap at 400% of the federal poverty level and higher required contribution percentages below it. A single enrollee earning $28,000 who paid about $325 a year under enhanced credits would owe closer to $1,562, per KFF modeling.

Here’s the catch that changes everything: even with these increases, a subsidized Marketplace plan frequently costs a fraction of COBRA. The tax credit does the heavy lifting COBRA never offers. If you’re weighing exchange plans against an employer group option, our guide to comparing small business health quotes beyond premium covers the network and deductible traps that list prices hide.
COBRA vs Marketplace: Which Is Better for a Recently Unemployed Single Adult?
Take a concrete case. Alex, 45, single, earned $52,000 before a layoff and had a PPO plan. COBRA would cost about $835 a month ($10,014 a year) to keep that exact plan. On the Marketplace, Alex’s $52,000 income sits at roughly 332% of the federal poverty level — under the 400% cap — so a premium tax credit still applies even without the enhanced version.
At that income, the original ACA formula caps Alex’s benchmark-plan contribution at a single-digit percentage of income, landing the net premium in the low-to-mid $300s per month for a benchmark silver plan — often less for a bronze plan. Against COBRA’s $835, the Marketplace saves Alex roughly $450–$500 a month, or $5,400–$6,000 a year, before accounting for deductible differences.
The picture inverts if Alex had already paid down a $4,000 deductible by October. Switching plans resets that to zero, so late-year continuity through COBRA can be worth more than the monthly savings. It also inverts above the subsidy cliff: an identical worker earning $85,000 gets no tax credit, pays full freight on both options, and usually finds the Marketplace bronze plan still cheaper than COBRA’s PPO — but the gap narrows sharply.
Verdict
For a subsidy-eligible single adult below 400% FPL with no large unmet deductible, the Marketplace wins decisively — typically $5,000+ in annual savings. COBRA wins only when you’ve already met most of your deductible for the year or have in-progress specialist care you can’t risk disrupting. Above the subsidy cliff, run both; the Marketplace usually still edges out COBRA, but the margin shrinks to hundreds rather than thousands.
How the 60-Day Window and Subsidy Eligibility Actually Interact
Timing rules trip up more people than pricing does. You have 60 days from losing coverage (or from your COBRA election notice, whichever is later) to elect COBRA, per the Department of Labor. That same job loss opens a 60-day Marketplace special enrollment period. These windows overlap — which is the key strategic opening most people miss.
You can elect COBRA and still switch to a Marketplace plan, provided you do it inside your original 60-day special enrollment period. CMS guidance confirms a consumer who elected COBRA may drop it for a Marketplace plan while that window remains open. Once the window closes, though, you’re generally locked into COBRA until it exhausts (up to 18 months) — and only then does exhaustion trigger a fresh special enrollment period.
One eligibility rule matters enormously: if you are merely eligible for COBRA but haven’t enrolled, you can still claim a premium tax credit on a Marketplace plan. But once you’re enrolled in COBRA, you generally cannot receive that tax credit for any month COBRA is active. That single distinction can be worth thousands. Households juggling coverage for varied staff should also review coverage obligations for part-time and seasonal staff and how ACA employer mandate requirements and compliance costs shape what a former employer offers.
What Most People Get Wrong About This Decision
Three mistakes recur, and each carries a measurable price tag.
Mistake 1: Electing COBRA before checking Marketplace subsidies. The consequence is forfeiting a premium tax credit for every month you stay on COBRA — potentially $400+ monthly for a subsidy-eligible single adult. The correct action is to price a Marketplace plan on HealthCare.gov first, because COBRA can be elected retroactively within your 60-day window anyway; you lose nothing by comparing before committing.
Mistake 2: Assuming your income disqualifies you. Many early retirees and mid-career professionals assume they earn too much. With the 400% FPL cap back for 2026, that’s a real threshold — roughly $62,750 for a single person — but plenty of laid-off workers fall under it precisely because their income dropped. The correct action is to estimate your actual 2026 income, not last year’s salary.
Mistake 3: Ignoring deductible reset timing. Switching plans mid-year zeroes out deductible and out-of-pocket progress. Someone who’s paid $3,000 toward a $4,000 deductible by August can lose that entirely by moving to a Marketplace plan. The correct action is to weigh unmet-deductible dollars against monthly premium savings before switching. For related cost-timing tactics, see how households handle renewal premium increases and negotiation tactics.
Who Should Choose COBRA, and Who Should Choose the Marketplace?
The decision resolves cleanly once you sort by three variables: income, deductible progress, and provider continuity. Choose COBRA if you’ve already met most of your annual deductible, you’re mid-treatment with specialists you can’t switch, or your income exceeds 400% FPL and your employer plan is unusually generous relative to available bronze plans.
Choose the Marketplace if your post-layoff income qualifies you for a premium tax credit, you’re early in the plan year with little deductible spent, or you simply can’t absorb COBRA’s $793–$2,294 monthly cost. For most subsidy-eligible people below the cliff, the Marketplace is the clear financial answer even after the 2026 subsidy reductions.
Two groups deserve special attention. Early retirees under 65 often see the widest COBRA-to-Marketplace savings because their taxable income drops the year they stop working — but they’re also the most exposed to the 400% cliff if they draw heavily from taxable accounts. Families with a member undergoing active treatment frequently find COBRA’s continuity worth its premium, since a network change can interrupt care. If you’re a business owner navigating this from the employer side, our comparisons of QSEHRA vs ICHRA cost and administration and PEO group plan cost reduction for small businesses outline alternatives to traditional group coverage.
Frequently Asked Questions
Is COBRA ever cheaper than a Marketplace plan?
Rarely on premium alone, but yes in specific cases. If your income exceeds 400% of the federal poverty level (about $62,750 for a single person in 2026), you get no premium tax credit, and a generous employer PPO can occasionally beat a comparable Marketplace plan on total value. COBRA also wins when you’ve met most of your deductible, since switching plans resets it to zero. Source: Congressional Research Service, KFF.
Can I switch from COBRA to a Marketplace plan mid-year?
Only in two situations. You can switch while your original 60-day special enrollment period is still open, or when your COBRA coverage fully exhausts (up to 18 months), which triggers a new special enrollment period. If you voluntarily drop COBRA or stop paying outside those windows, you must wait for open enrollment. This is confirmed by CMS Marketplace guidance.
Did the enhanced premium tax credits get extended for 2026?
As of the most recent verified data, the enhanced credits expired December 31, 2025. The House passed a three-year extension by a 230–196 vote on January 8, 2026, but the Senate had not enacted it. Because this directly changes Marketplace costs, confirm current status at HealthCare.gov before deciding. Source: Congress.gov, KFF.
Why is COBRA 102% of the premium?
Federal law lets the plan charge 100% of the full premium — both the employee and former-employer portions — plus a 2% administrative fee, for a 102% cap. During a disability extension (months 19–29), that ceiling rises to 150%. The fee is optional for the employer to charge, per U.S. Department of Labor rules, but most apply it.
How We Researched This Article
This comparison draws on primary federal and institutional sources, verified before publication. Employer premium and worker-contribution figures — $9,325 single and $26,993 family, with worker contributions of $1,440 and $6,850 respectively — come from the KFF 2025 Employer Health Benefits Survey, which interviewed 1,862 firms. COBRA’s 102% cap, 2% administrative fee, 60-day election window, and up-to-18-month duration are drawn from U.S. Department of Labor guidance.
Marketplace figures reflect 2026 rate filings and subsidy analysis. The 21.7% benchmark premium increase comes from the Urban Institute; the 114% average net-premium increase and $1,016 estimate come from KFF; the 400% FPL cap reversion and CBO premium projections come from the Congressional Research Service. Special-enrollment interaction rules were confirmed against HealthCare.gov and CMS materials.
The scenario figures (Alex at $52,000, the deductible-reset examples) are modeled illustrations applying the ACA’s original subsidy formula to KFF premium averages — they are calculated estimates, not measured survey results, and individual costs vary by ZIP code, age, and plan. The single largest uncertainty is legislative: the enhanced tax credit’s fate was unresolved in the Senate as of our last verified data, and any extension would materially lower Marketplace net premiums. Research last conducted July 2026. All figures were verified against named primary sources before publication.
