COBRA allows you to continue your employer's health plan for 18-36 months after job loss, but at full cost (employer + employee share) plus a 2% admin fee — averaging $650-$750/month for individual coverage. ACA Marketplace plans may cost significantly less with premium subsidies based on income, making them the better choice for most people.
Losing employer health insurance is one of the most stressful aspects of job loss. You have 60 days to make a decision that could cost you thousands of dollars either way. Here is the complete comparison to help you choose wisely.
What Happens to Your Health Insurance When You Lose Your Job
COBRA is a federal law allowing temporary continuation of employer health insurance at full cost after job loss, while the ACA Marketplace is the government exchange offering subsidized health plans.
Your employer health coverage typically ends on the last day of the month in which you separate, though some employers cut coverage on the last day of employment. At that point, you have two primary options: COBRA continuation and the ACA Health Insurance Marketplace. You qualify for a Special Enrollment Period on the marketplace, giving you 60 days to enroll regardless of the annual open enrollment window.
This timing detail matters: you can take the full 60 days to decide on COBRA, and if you get sick during that period, you can elect COBRA retroactively to cover any medical expenses incurred. This makes COBRA a useful safety net during the transition even if you ultimately plan to choose marketplace coverage.
The COBRA Cost Shock
COBRA lets you keep your exact employer plan including the same doctors, network, prescriptions, and deductible progress. The catch: you pay 102% of the full premium. Most employees only see their share of health insurance costs, typically 17-27% of the total premium. Under COBRA, you pay the entire amount plus a 2% administrative fee.
Real numbers: if your employer plan costs $1,800/month total and you were paying $350/month as an employee, your COBRA cost is $1,836/month, a 425% increase from what you were paying. For family coverage averaging $2,200/month total, COBRA costs $2,244/month. Over the full 18-month COBRA period, that is $33,048 for individual coverage or $40,392 for family coverage. Compare your specific costs with our COBRA Cost Calculator.
The ACA Marketplace Alternative
The ACA marketplace often provides significant savings, especially if your income drops after job loss. Marketplace subsidies are based on your projected annual income for the coverage year. If you lose your job in March and expect to earn significantly less for the remaining year, your subsidy could be substantial.
A single individual projecting $40,000 in annual income can expect a Silver plan costing approximately $400-$600/month after subsidies in most markets, compared to $1,836 for COBRA. A family of four at $60,000 projected income might pay $200-$400/month after subsidies. The savings can be enormous: $1,200+ per month less than COBRA.
The trade-off: you may need to change doctors and networks. If your marketplace plan uses a narrower network, your current specialists may not be covered. Check provider directories carefully before enrolling. Also, your deductible resets with a new plan, so if you have already met a significant portion of your employer plan deductible, that progress is lost.
When COBRA Is Actually Worth It
Despite the high cost, COBRA makes financial sense in specific situations. You are mid-treatment: if you are undergoing chemotherapy, physical therapy, or have a scheduled surgery, switching plans mid-treatment can be disruptive and expensive. Keeping your current plan ensures continuity of care with your established providers. You have met your deductible: if you have already spent $4,000 toward a $5,000 deductible and expect more medical expenses, starting over with a new deductible could cost more than the COBRA premium difference.
You are close to Medicare eligibility: if you are 64 and will be eligible for Medicare in a few months, COBRA bridges the gap without disrupting provider relationships. You have a high-risk pregnancy or chronic condition: the predictability of keeping your current plan may be worth the premium, especially if your providers are not in marketplace networks.
The Strategic Approach
The optimal strategy for most people: elect COBRA within the 60-day window but simultaneously shop the marketplace. You can elect COBRA at any point within 60 days and coverage is retroactive, so you are protected during the evaluation period. Compare marketplace plan networks to verify your doctors are covered, calculate the subsidy based on your projected income, and make the final decision before your 60 days expire.
If marketplace coverage is cheaper and your providers are in-network, switch to marketplace. If you are mid-treatment or the cost difference is small, keep COBRA for continuity. Remember that you can switch from COBRA to marketplace during the next open enrollment period. Plan your overall finances during the transition with our Budget Calculator.
Planning Beyond the 18-Month COBRA Window
COBRA coverage has a hard expiration: 18 months for job loss, 36 months for divorce or dependent aging out. Planning for what comes next should begin immediately, not when the deadline approaches. If you have not secured new employer coverage by month 15 of COBRA, start actively shopping the ACA marketplace for the next annual open enrollment period. Many people forget that COBRA expiration itself qualifies you for a Special Enrollment Period, giving you 60 days to enroll in marketplace coverage.
For those approaching age 65 during COBRA, the transition to Medicare requires careful timing. Medicare enrollment begins 3 months before your 65th birthday month and extends 3 months after. Missing this Initial Enrollment Period results in permanent premium penalties on Part B and Part D. Coordinate your COBRA end date with Medicare start date to avoid any coverage gaps. Our Medicare Comparison Calculator helps you evaluate original Medicare versus Medicare Advantage plans.
If you are self-employed or starting a business after job loss, the ACA marketplace is your long-term health coverage solution. Marketplace premiums are based on projected income, and new business owners with initially low income often qualify for substantial subsidies. A sole proprietor projecting $50,000 in year-one income for a family of four could receive monthly subsidies of $1,000 or more, making comprehensive coverage affordable during the business-building phase. Health coverage should be a line item in every business plan. Factor your full benefits costs with our Health Insurance Calculator.

The 2026 Cost Reality: COBRA vs Marketplace Numbers
COBRA typically costs $500-2,000+ per month because you pay 100% of the premium your employer previously subsidized, plus a 2% administrative fee. The average employer-sponsored family plan costs over $24,000/year — meaning a family on COBRA could pay $2,000+/month for the same coverage that cost them $500/month while employed. ACA Marketplace plans with subsidies can cost $0-500/month, with the average family saving $800-1,200/month compared to COBRA.
A critical 2026 change: enhanced ACA subsidies under the Inflation Reduction Act expired on December 31, 2025. According to KFF, the average subsidized enrollee who paid approximately $888/year in 2025 is now looking at roughly $1,904/year in 2026 — more than double. For moderate-to-high income individuals, marketplace premiums in 2026 may be as expensive as COBRA, making the comparison closer than in previous years. However, for lower-income individuals and families (below 400% of the federal poverty level), subsidies still significantly reduce marketplace costs below COBRA rates.
You have 60 days from losing coverage to elect COBRA or enroll in a Marketplace plan. This is your Special Enrollment Period — do not let it expire without taking action. Both options provide retroactive coverage (COBRA covers you from the date of job loss; Marketplace covers you from the enrollment date), but COBRA gives you 45 days to make your first payment, allowing you to effectively wait and only pay if you need care during the gap period.
The Decision Framework: 5 Questions That Determine Your Best Option
Question 1: Are you mid-treatment? If you are in the middle of cancer treatment, pregnancy, surgery recovery, or managing a complex chronic condition, COBRA preserves your existing doctors, specialists, and treatment continuity. Switching plans mid-treatment risks provider disruption, prior authorization delays, and formulary changes that could interrupt medication. In these situations, COBRA's higher cost is worth the continuity — potentially saving thousands in complications or treatment delays.
Question 2: Have you already met your deductible? If you have met your employer plan's $3,000-6,000 deductible this year, switching to a new Marketplace plan resets it to zero. COBRA preserves your progress toward the deductible and out-of-pocket maximum. If it is October and you have already spent $4,000 toward a $6,000 deductible, COBRA for the remaining 3 months saves you from re-spending that amount on a new plan.
Question 3: What is your projected income for the year? ACA subsidies are based on annual income. If you lost your job in June and expect to earn $50,000 total for the year (half your normal $100,000 salary), your reduced income qualifies you for larger subsidies than if you had worked the full year. Run your projected annual income through the healthcare.gov calculator to see subsidy amounts before deciding.
Question 4: How long will you need coverage? If you expect to start a new job with benefits within 2-3 months, COBRA's simplicity (same plan, same doctors) may be worth the premium for a short bridge period. If you expect to be uninsured for 6-18 months (starting a business, extended job search, early retirement), the Marketplace's lower monthly cost adds up to significant savings: $800/month saved over 12 months = $9,600.
Question 5: Do you have an HSA? If you have a Health Savings Account with a balance, you can use HSA funds tax-free to pay COBRA premiums — one of the few times HSA money can cover insurance premiums. A $10,000 HSA balance could fund 5-10 months of COBRA at $1,000-2,000/month, making COBRA effectively free from your current cash flow.
The COBRA Backdoor Strategy Most People Miss
Here is a sophisticated strategy that gives you the safety net of COBRA without paying unless you need it: elect COBRA but delay payment. You have 60 days to elect COBRA, then 45 days after election to make your first payment. This gives you up to 105 days of "free" coverage — if you need medical care during this window, you pay the premiums retroactively. If you remain healthy and secure new coverage, you simply never pay and COBRA lapses. Meanwhile, also enroll in a Marketplace plan starting the first of the following month.
This strategy works because COBRA is retroactive — if you have a medical emergency during the gap, you can elect COBRA and pay the back premiums to activate coverage for the emergency. You are not gambling with being uninsured; you are deferring the payment decision until you know whether you need it. The risk: if you have a major medical event late in the election window, you will owe several months of premiums all at once. But for healthy individuals in transition, this approach can save $2,000-6,000 in premiums during the gap period.
What Your Result Means
ACA cheaper than COBRA (most situations): If household income is under 400% FPL ($62,400 single / $129,000 family of 4 in 2026): ACA subsidies make marketplace plans significantly cheaper. Switch unless your current doctors are not in any marketplace plan network.
COBRA cheaper (rare — high income, expensive marketplace area): At incomes above subsidy thresholds in expensive ACA markets, COBRA may cost less for the first 18 months. But COBRA expires — have a marketplace transition plan ready at month 15.
