Choosing Between COBRA and Marketplace Health Insurance

COBRA and marketplace coverage are your two main routes after you lose employer insurance, and they work very differently

COBRA lets you keep your old employer plan for up to 18 months, but you pay the full premium yourself — usually $400 to $800 a month or more. Marketplace coverage is insurance you buy directly from your state's health insurance marketplace, and you may pay less if your income qualifies you for a tax credit that reduces the monthly cost.

The choice depends on three things: whether your old plan was good and affordable enough to keep paying for, whether you have a gap in coverage (COBRA has a 60-day window to enroll), and whether a marketplace plan with a tax credit would cost you less. Most people find marketplace coverage cheaper, but some need COBRA because they have doctors or prescriptions tied to their current plan.

Key Takeaways

• COBRA continues your current employer plan but costs you the full premium plus a 2% administrative fee, while marketplace plans may cost less if you receive a tax credit based on your income.
• You have 60 days from the date you lose coverage to enroll in COBRA, and you must enroll within that window or you lose the option entirely.
• Marketplace open enrollment runs from November 1 to January 15 each year, but losing employer coverage counts as a life event that lets you enroll outside those dates.
• Your choice should factor in whether your doctors and prescriptions are in-network on each plan, because switching plans means switching networks.
• If you cannot afford either option, you may be uninsured for a short time, but you can enroll in marketplace coverage as soon as you lose your job or turn 26.

How COBRA works and what it actually costs

COBRA is a federal law that requires your employer's health plan to let you stay on it after you lose coverage. Your employer must notify you within 14 days of the event that triggers COBRA may be able to access — usually losing your job, having your hours cut below full-time, or aging off a parent's plan. You then have 60 days to decide whether to enroll.

The cost is the full monthly premium your employer was paying, plus the employee share your paycheck was deducting, plus a 2% administrative fee. If your employer was paying $600 and you were paying $200, you now pay $816 per month. Many people are shocked by this number because they only saw their own share on their paystub.

COBRA coverage lasts up to 18 months in most cases. If you lost coverage because you were fired (not for cause), you get the full 18 months. If you quit or were fired for cause, you still get COBRA, but some employers try to argue otherwise — push back if this happens to you. If you turn 26 and age off a parent's plan, COBRA lasts 36 months.

How marketplace coverage works and when you can enroll

Marketplace coverage is health insurance sold through your state's official marketplace — usually Healthcare.gov if your state does not run its own. You browse plans, compare prices and networks, and enroll directly. Open enrollment normally runs November 1 to January 15, but losing employer coverage is a may have access to life event that lets you enroll outside those dates.

When you enroll, you report your expected household income for the year. If your income is between 100% and 400% of the federal poverty line (roughly $14,600 to $58,400 for a single person in 2024, though this changes yearly), you may receive a tax credit that lowers your monthly premium. The credit is applied immediately at the time you enroll, so your monthly bill reflects it right away.

You have 60 days from the date you lose coverage to enroll in marketplace coverage using the life event. After 60 days, you cannot enroll until the next open enrollment period in November, unless another may have access to event happens. This is why timing matters: if you wait too long, you could be uninsured for months.

Comparing costs: COBRA versus marketplace with a tax credit

The real cost comparison is COBRA's full premium against a marketplace plan's premium after your tax credit. If COBRA costs $800 and a marketplace plan costs $600 but you receive a $250 monthly tax credit, your actual marketplace cost is $350 — much cheaper.

However, the tax credit is based on your income estimate. If you report that you will earn $35,000 this year but actually earn $50,000, you will owe back some or all of the credit when you file taxes. Estimate conservatively: if you are between jobs or your income is uncertain, report the lower number and adjust later if you earn more.

Some people find that no marketplace plan is affordable even with a tax credit, especially if their income is just above the threshold for the largest credits. In those cases, COBRA may be the better choice for a few months while you look for new employment with benefits. Others find that COBRA is cheaper because they have a very low income and receive a large tax credit, making the marketplace plan nearly free.

Network and provider differences between the two

Your current employer plan has a specific network of doctors, hospitals, and pharmacies. COBRA keeps you in that exact network. If you switch to a marketplace plan, you get a different network — sometimes completely different, sometimes overlapping.

Before you choose, check whether your current doctors and specialists are in-network on the marketplace plans you are considering. Call your doctor's office and ask which marketplace plans they accept. If your doctor is not in any affordable marketplace plan, COBRA may be worth the cost to avoid switching mid-treatment.

The same applies to prescriptions. If you take a medication that is only covered by your current plan's formulary, switching plans could mean a higher copay or a requirement to try a different drug first. Ask your pharmacy which marketplace plans cover your current medications at the same cost.

What happens if you miss the COBRA deadline

If you do not enroll in COBRA within 60 days of losing coverage, you lose the option permanently. You cannot go back and enroll later. However, you can still enroll in marketplace coverage if you are within 60 days of the life event, or you can wait for open enrollment in November.

If you miss both deadlines and do not enroll in any coverage, you will be uninsured. You can still enroll in marketplace coverage during the next open enrollment period (November 1 to January 15), but you will have a gap in coverage. A gap of a few months usually does not result in a tax penalty, but it does mean you have no insurance if you get sick or injured.

Some people intentionally skip both COBRA and marketplace coverage because they are young and healthy and cannot afford either. This is a real choice some people make, but it is a risk. If you have an accident or unexpected illness, you could face medical debt. A catastrophic marketplace plan, if available in your state, costs less than COBRA and covers emergencies.

When to choose COBRA and when to choose marketplace coverage

Choose COBRA if: you have a plan you love with doctors and specialists you do not want to leave, your income is high enough that you do not receive a large marketplace tax credit, you are only between jobs for a few months and can afford the premium, or you have a chronic condition with medications that are only covered by your current plan's formulary.

Choose marketplace coverage if: the monthly premium after your tax credit is significantly lower than COBRA, your income qualifies you for a substantial tax credit, you do not have strong ties to your current doctors, or you are unemployed and need the lowest possible cost. Marketplace coverage is also the better choice if you are self-employed or starting a business, because you can adjust your income estimate as your earnings change.

If you are unsure, enroll in marketplace coverage first — you have 60 days to change your mind and switch to COBRA if you want to. Once you enroll in marketplace coverage, you can still enroll in COBRA within the 60-day window. But if you enroll in COBRA first and then want to switch to marketplace coverage, you can do so, though you will have paid COBRA premiums in the meantime.

Frequently Asked Questions

Can I enroll in COBRA and marketplace coverage at the same time?

No. You can only be enrolled in one health plan at a time. However, you can enroll in one, then switch to the other within the 60-day window. If you enroll in marketplace coverage and then decide you want COBRA instead, you can cancel the marketplace plan and enroll in COBRA before the 60 days are up.

What if I get a new job with health insurance before my COBRA runs out?

You can cancel COBRA at any time and enroll in your new employer's plan. Your new employer's plan will have its own waiting period or start date — usually the first of the month after you are hired, or 30 to 60 days after your start date. Check your new employer's benefits guide to see when coverage begins.

Do I have to pay back my marketplace tax credit if I get a job mid-year?

Only if your actual income is higher than you estimated. When you enroll, you report your expected income for the full year. If you get a job and your income goes up, you should update your marketplace account to report the new income. This adjusts your tax credit going forward. At tax time, if your actual income was higher than you reported, you may owe back some of the credit.

What if I cannot afford either COBRA or marketplace coverage?

Look for a catastrophic marketplace plan if you are under 30 or have a hardship exemption. Catastrophic plans have lower premiums but higher deductibles. You can also look into whether you may have access to for Medicaid, which is free or very low cost. Call 211 or visit your state's Medicaid website to check.

Can I switch from COBRA to marketplace coverage after I enroll in COBRA?

Yes, but only during marketplace open enrollment (November 1 to January 15) or if you have another may have access to life event, like getting married or having a child. If you enroll in COBRA in March and want to switch to marketplace coverage in June, you cannot do so until November unless something else changes.
