Why COBRA Is Almost Never the Right Long-Term Answer

When you lose job-based coverage, COBRA lets you stay on the same employer plan, but at a dramatically different price. The employer stops subsidizing your premium, and you pick up the full cost plus a 2% administrative fee. What felt like a $120/month payroll deduction can become an $800+/month bill overnight. That structure is why COBRA is rarely a sustainable long-term answer.

What COBRA actually costs

Under federal COBRA rules, you can be charged up to 102% of the total plan premium, both the employee share and the employer share, plus a 2% administrative fee. In certain disability extension months, that ceiling rises to 150%.

The 2025 national average employer plan premium is $9,325 per year for single coverage and $26,993 per year for family coverage. Workers typically contributed $1,440/year (single) and $6,850/year (family) while employed, because the employer paid the rest.

By comparison, CMS projected that eligible enrollees on HealthCare.gov could access the lowest-cost plan for an average of about $50/month after tax credits in 2026. Even accounting for the expiration of enhanced subsidies, the Marketplace option is frequently far cheaper than COBRA for households with subsidy eligibility.

The structural problems with COBRA long-term

It is time-limited by design

COBRA continuation coverage is available for a maximum of 18 months for the most common qualifying event (job loss or reduction in hours). Some situations extend this to 29 or 36 months. But "available" isn't the same as "financially sustainable", and every COBRA period ends with a forced transition to a new plan.

It depends on your former employer's decisions

You stay on the employer's plan, which means the employer can change the plan design, switch carriers, or, if they stop offering group coverage entirely, end your COBRA early regardless of where you are in the 18-month window. This isn't portable coverage. It's temporary continuation of someone else's plan.

Ending it early creates a trap

If you voluntarily cancel COBRA before it expires, you generally can't enroll in a Marketplace plan outside of Open Enrollment. You'd need to wait for the next Open Enrollment period (November 1 – January 15) or experience another qualifying life event. By contrast, if you exhaust COBRA, let it run to its natural end, and that exhaustion triggers a special enrollment opportunity. The sequence matters.

When COBRA does make sense

There are three narrow scenarios where COBRA is the rational short-term choice:

• You have a new employer plan starting in under 3 months. Paying two or three months of COBRA premiums to bridge the gap, especially if the new plan has the same or better network, is often cleaner than switching plans mid-treatment.
• You are mid-treatment in a specific network. Switching plans mid-episode can disrupt care continuity. If you're in active treatment with a specialist or facility tied to the employer's network, COBRA buys you the time to complete that course of care before transitioning.
• Your former employer is subsidizing the COBRA premium. Some severance packages include employer-paid COBRA for a defined period. That changes the math significantly. Free COBRA is genuinely competitive with most alternatives.

In each case, the key word is "short-term." Set a calendar date to reassess. Don't let COBRA auto-renew simply because it feels easier.

The alternatives to compare

Losing job-based coverage is a qualifying life event that triggers a 60-day special enrollment period on the Marketplace. You can shop and enroll in an ACA plan during those 60 days. If you have a spouse or domestic partner with employer coverage, their plan also triggers a 30-day special enrollment window. Medicaid enrollment is available year-round in expansion states for households up to 138% FPL.

One important tax note: HSA funds can be used to pay COBRA premiums. It's one of the few insurance premium categories the IRS allows. If you have a funded HSA, this can reduce the effective after-tax cost of a short COBRA bridge.

Preexisting conditions: no longer a reason to stay on COBRA

The historical argument for sticking with COBRA, protecting coverage for preexisting conditions, no longer applies. ACA-compliant Marketplace plans are guaranteed issue and can't exclude or limit coverage based on medical history. If your care needs are ongoing, the issue is network continuity and deductible positioning, not whether you can get coverage.

Bottom line

COBRA is a bridge, not a destination. Compute the full COBRA premium (not your old payroll deduction), immediately shop the Marketplace for comparison, check for Medicaid eligibility, and ask about your spouse's employer plan, all before you commit. If your net Marketplace premium is lower and your providers are in-network, there's usually no reason to pay the COBRA rate for more than a month or two.
