What Is COBRA and How Does It Work?
COBRA — the Consolidated Omnibus Budget Reconciliation Act — is a federal law that requires employers with 20 or more employees to offer departing workers the option to continue their group health insurance for up to 18 months (or longer in certain circumstances such as disability or a second qualifying event). When you elect COBRA, you keep the exact same plan, network, deductible, and benefits you had as an active employee.
The catch: you now pay the full premium. As an employee, you only saw your share — typically 20%–30% of the premium, with your employer picking up the rest. Under COBRA, you pay 100% plus a 2% administrative fee. That's why COBRA often feels like a shock when you see the actual cost.
The COBRA Premium Reality Check: The average employer contributes about $7,200/year toward a single employee's health premium and over $20,000/year for family coverage. When you elect COBRA, you inherit those contributions yourself. A family plan that cost you $300/month as an employee might now cost $1,800+/month under COBRA.
What Are ACA Marketplace Plans?
ACA marketplace plans (also called Obamacare plans or exchange plans) are private health insurance plans sold on state or federal marketplaces and certified to meet Affordable Care Act standards. They must cover the ten essential health benefits, cannot deny coverage for pre-existing conditions, and are available to anyone who needs individual or family coverage without a limit on annual benefits.
The critical difference from COBRA: marketplace plans come with premium tax credits — federal subsidies based on your income that can dramatically reduce your monthly premium. Since losing a job typically reduces your income (at least temporarily), you may suddenly qualify for subsidies you wouldn't have been eligible for while working.
COBRA vs. Marketplace: A Side-by-Side Comparison
Cost
This is where marketplace plans almost always win. Consider a family of three where one parent earned $70,000 and now leaves their job. Without that income, the family's projected 2026 income might be $30,000 (from a part-time job or savings). At $30,000 for a family of three, they qualify for a substantial ACA subsidy — enough to reduce a $1,500/month Silver plan to perhaps $150–$250/month after the premium tax credit. Their COBRA premium for the same employer family plan might be $1,700–$1,900/month.
The math is stark: marketplace subsidies can save $1,000–$1,500/month for a family in this scenario.
Coverage and Network
COBRA wins here on continuity. Your COBRA plan is literally your same plan — same network, same deductibles already partially met, same prescription coverage. If you've met a significant portion of your deductible, switching to a marketplace plan resets that clock. If you're in the middle of treatment for a chronic condition or recovering from surgery, COBRA may actually save you money overall despite the higher premium.
Flexibility
Marketplace plans offer more choice — you can pick a carrier and plan specifically suited to your situation in 2026. COBRA locks you into the plan your employer offered. If that was a gold-plated PPO that's now overkill for your situation, you're stuck paying for it.
Duration
COBRA lasts up to 18 months (sometimes longer). ACA marketplace coverage renews annually with no time limit — as long as you continue to need individual coverage, you can keep a marketplace plan indefinitely.
The Deductible Reset Calculation: If you've already met $3,000 of a $4,000 deductible and switch to a marketplace plan, you start over at $0 toward a new deductible. That $3,000 credit disappears. Calculate whether the premium savings from the marketplace plan outweigh the deductible reset — for expensive ongoing care, COBRA might temporarily be the better financial choice even with higher premiums.
When COBRA Might Make Sense
COBRA is not always the wrong choice. Consider keeping COBRA if:
- Your income is high enough that you wouldn't qualify for meaningful marketplace subsidies, and your employer plan is excellent
- You've met most of your annual deductible and have significant ongoing medical expenses that would reset under a new plan
- You have a specific specialist or hospital relationship that's in-network on your employer plan but might not be on available marketplace plans
- You expect to quickly transition to a new employer with benefits — COBRA buys time without a network change
- You're within a few months of Medicare eligibility (65) and want continuity
When the Marketplace Almost Always Wins
Choose a marketplace plan over COBRA when:
- Your income drops significantly after job loss, making you eligible for large premium tax credits
- Your COBRA premium is more than $400–$500/month for individual coverage or $1,000+/month for family coverage
- You're healthy and rarely use medical care — a subsidized Bronze plan might cover your needs at a fraction of COBRA's cost
- You're early in your plan year with little deductible progress made
- You want access to local or different carriers with potentially better networks in your new situation
Don't Default to COBRA Out of Fear: Many people elect COBRA automatically because it feels safe and familiar. This is understandable — but it can cost thousands of extra dollars per month. You have 60 days to decide, and the 60-day Special Enrollment Period for marketplace plans runs simultaneously. Use that time to get actual quotes and compare real numbers before deciding.
The 60-Day Window: Don't Miss It
Both your COBRA election period and your marketplace Special Enrollment Period run for 60 days from your loss of employer coverage. These windows overlap completely — you can explore both options in parallel before making a decision. Key deadlines:
- Day 0: Lose employer coverage (or date it ends)
- Day 60: Deadline to elect COBRA OR enroll in a marketplace plan through an SEP
- Act quickly: Marketplace enrollment can take a few days to process; don't wait until day 58
If you want coverage with no gap, the safest strategy is to enroll in a marketplace plan within the first few days of becoming eligible (the SEP), then cancel it if you later decide COBRA is better — or simply let the marketplace plan take effect on the 1st of the following month.
Step-by-Step: Evaluating COBRA vs. Marketplace
- Get your COBRA election notice — it shows your exact COBRA premium cost
- Estimate your projected annual income for the remainder of the year
- Visit HealthCare.gov (or your state's marketplace) and input your income and household size to see your subsidy estimate
- Get marketplace plan quotes for your county — compare premiums, deductibles, networks
- Check whether your current doctors participate in available marketplace plans
- Calculate your deductible progress on your current plan and what it would cost to reset
- Make a fully informed decision with a licensed broker if needed
Frequently Asked Questions
Is COBRA always more expensive than marketplace insurance?
Almost always, yes. COBRA requires you to pay 102% of the full premium — including the share your employer was paying on your behalf, which most employees never see. The average employer pays about 70% of a family plan's premium. Once you have to pay it all yourself, COBRA typically runs $700–$2,000/month for a family. An ACA marketplace plan with subsidies can cost a fraction of that.
How long do I have to decide between COBRA and marketplace?
You have 60 days from losing employer coverage to elect COBRA, and 60 days from losing coverage to enroll in a marketplace plan through a Special Enrollment Period. These windows overlap, so you can compare both options simultaneously before making a decision.
What happens to my doctors if I switch from COBRA to marketplace?
When you switch from COBRA to a marketplace plan, your provider network will change. Before switching, verify that your current doctors, specialists, and preferred hospitals are in-network on the marketplace plan you're considering. If continuity of care with specific providers is critical, this verification must happen before you enroll.
Can I go back to COBRA after enrolling in a marketplace plan?
Generally no — once you've voluntarily declined COBRA or switched away from it to a marketplace plan, you typically cannot go back to COBRA. This is why it's important to make a fully informed comparison before deciding. A licensed broker can help you model both options side by side with real numbers.
