Insurance
COBRA keeps your exact plan at full unsubsidised cost. Marketplace coverage may cost a fraction of it. The deciding factor is income.

After losing employer coverage you have two main routes: continue the same plan through COBRA, or buy coverage on the health insurance marketplace. COBRA is usually far more expensive because you pay the full premium your employer had been subsidising. Marketplace coverage may be substantially subsidised depending on your income for the year, and that single variable usually decides the answer.
Your payroll deduction was your share. Employers typically pay the larger part of the premium, so COBRA's full cost commonly runs three to five times what appeared on your payslip, plus a small administrative charge the plan is permitted to add. Nothing about the coverage changed; the subsidy disappeared.
The Department of Labor administers COBRA continuation rules, and the entitlement generally runs for a limited period after qualifying employment ends. It matters because COBRA is a bridge with an expiry date, not a long-term arrangement.
| Factor | COBRA | Marketplace |
|---|---|---|
| Premium | Full unsubsidised cost plus admin fee | May be heavily subsidised by income |
| Your plan and network | Identical to before | New plan, network must be checked |
| Deductible already met this year | Carries over | Resets to zero |
| Duration | Limited continuation period | Ongoing, renewed annually |
| Enrolment window | Election period after the qualifying event | Special enrolment period after job loss |
| Best suited to | Mid-treatment, or deductible already met | Most people, especially on reduced income |
Two situations justify the higher cost. First, if you are mid-treatment: switching plans mid-course can change your specialists, your prior authorisations and your formulary tier, and continuity is worth real money in that situation. Second, if you have already met a large deductible this year, since marketplace coverage restarts it at zero.
A household that has already paid $6,000 toward a deductible and expects further care may find COBRA cheaper in total for the remainder of the year despite the much larger premium, purely because the marketplace plan would require meeting a new deductible from scratch.
Same family, two very different answers (2026)
Family of four, employer plan ends 30 June COBRA quote Full monthly premium $1,880 Plus 2% administrative charge $38 Six months of COBRA $11,508 Deductible already met this year $5,200 Marketplace, household income $58,000 Benchmark plan before subsidy $1,640/mo Premium after income-based subsidy $310/mo Six months $1,860 New deductible to meet $3,400 Worst case six-month cost $5,260 Marketplace cheaper by $6,248 Marketplace, household income $185,000 Little or no subsidy applies Six months at full cost $9,840 Plus new deductible $3,400 Worst case $13,240 COBRA cheaper by $1,732 The plan did not change. Income decided it.
That is the practical rule. On a reduced income, marketplace subsidies usually make it the clear choice; on a high income with a large deductible already met, COBRA can win.
Estimate your income for the whole calendar year, not your former salary, since marketplace subsidies are based on annual household income and a mid-year job loss lowers it substantially. Then verify that your doctors and prescriptions are covered under the marketplace plan you are considering.
The Centers for Medicare and Medicaid Services publishes standardised plan information for marketplace coverage, which makes side-by-side comparison of deductibles and cost sharing possible. Get the actual COBRA figure in writing from the plan administrator rather than estimating from your old payslip, because the two bear no relation to each other.
