Losing employer-sponsored health insurance is one of the most common reasons Floridians shop for coverage. When it happens, you typically face two options: elect COBRA to continue your employer plan, or enroll in an ACA marketplace plan. Most people assume COBRA is the safer or simpler choice. Most of the time, they are wrong — and the cost difference can be staggering.
This guide compares both options on cost, coverage quality, enrollment timing, and the specific situations where each actually makes sense in 2026.
The instinct to elect COBRA is understandable. You keep the same doctors, the same network, the same drug formulary. You don't have to research new plans. But COBRA is not subsidized health insurance — it is continuation coverage, and you pay the full unsubsidized cost plus a 2% administrative fee.
When you had employer coverage, your employer was likely paying $600–$1,200 per month toward your premium and you only saw the employee payroll deduction. Under COBRA, that employer contribution disappears. You pay both sides. For a family plan, that can mean a monthly COBRA bill of $1,800–$2,500 or more — for the exact same coverage you thought cost you $300/month.
Meanwhile, the ACA marketplace offers subsidized private health insurance with premiums that, for many Floridians, are dramatically lower than COBRA — and in some cases $0/month after premium tax credits. The trade-off is a potential network or formulary change, which matters in some situations but not in most.
COBRA allows you to continue your employer-sponsored group health plan for up to 18 months (36 months in some circumstances) after losing eligibility. The premium you pay under COBRA is the full group premium — both the portion you paid as an employee and the portion your employer contributed — plus up to 2% for administrative costs.
In practice, this means:
These figures represent actual premium costs for 2026 Florida employer group plans across common industries. High-cost employer plans — common in small-group markets and certain industries — can run even higher.
ACA marketplace premiums are reduced by the Advance Premium Tax Credit (APTC), which is calculated based on your projected annual household income relative to the Federal Poverty Level. The benchmark for subsidy calculation is the second-lowest-cost Silver plan ("benchmark Silver") in your county.
For 2026, the ACA subsidy system works as follows for a single adult in Florida:
A Bronze plan — which has higher deductibles but lower premiums — can often be selected at $0/month or near-$0/month for individuals with incomes below 250% FPL after APTC is applied. Families see proportionally higher subsidies.
The critical point: when you leave employment and your income is reduced (or you project a lower income for the remainder of the year), your eligibility for APTC may be substantially higher than you expect. A person earning $70,000 in the first half of the year who loses their job may have an annualized income well below 400% FPL for the full year, qualifying for meaningful subsidies.
| Factor | COBRA | ACA Marketplace |
|---|---|---|
| Monthly cost (family) | $1,700–$2,400+ (full group premium + 2%) | $0–$600+/month after APTC subsidies (income-dependent) |
| Coverage quality | Same as your employer plan — no change | ACA-compliant; comparable essential health benefits |
| Network continuity | Same network — existing doctors and specialists | New network; may or may not include current providers |
| Drug formulary | Same formulary — existing prescriptions covered as before | Different formulary; verify specific drugs before enrolling |
| Enrollment deadline | 60 days from loss of coverage to elect COBRA | 60 days from qualifying event (job loss) to enroll |
| Coverage start date | Retroactive — no gap if elected within 60 days | Generally first of the following month |
| Maximum duration | 18 months (36 in some cases) | Annual; renews each year during open enrollment |
| Subsidy available | No — full premium plus admin fee | Yes — APTC and CSR based on income |
Despite the cost disadvantage, there are specific situations where COBRA is genuinely the better choice:
Very short gap (under 2 months): If you know you will start a new job with employer coverage in 4–6 weeks, the disruption of switching plans may not be worth it. COBRA allows you to avoid any coverage gap and maintain continuity. Note that you can elect COBRA retroactively if something goes wrong during the gap — you have 60 days to decide whether to elect, and if you need care, you can elect retroactively and pay the premiums owed.
Active complex treatment with in-network specialist: If you are mid-treatment for cancer, a serious chronic condition, or have scheduled surgery with a specific specialist who is not in any ACA marketplace network in your area, COBRA continuity may protect treatment access more reliably than switching networks mid-treatment. Verify whether your specialist is in-network on available marketplace plans before making this determination — many Florida Blue and Ambetter networks do include major hospital systems.
Critical prescription drug on group formulary: Some specialty drugs — particularly biologic medications — have very different formulary placement and cost-sharing structures between group plans and individual ACA plans. If you take a high-cost specialty drug that is on your employer's formulary at a favorable tier, compare formularies carefully before switching.
Very high income (not subsidy-eligible): If your income is substantially above the subsidy thresholds and your employer plan had a particularly broad network or low deductibles, COBRA might be comparable to unsubsidized marketplace premiums for a similar plan. Run both numbers — but this scenario is relatively uncommon.
Before making the COBRA vs. ACA decision, complete this calculation:
Step 1: Get your COBRA election notice. It will show the full monthly premium for each coverage tier you are eligible to continue (employee only, employee + spouse, family, etc.). This is your COBRA monthly cost.
Step 2: Estimate your projected annual household income for the full calendar year. Include any severance, unemployment benefits, investment income, and any expected income from new employment. Be realistic — underestimating income leads to subsidy repayment at tax time.
Step 3: Go to HealthCare.gov or use a Florida licensed agent's quoting tool. Enter your income and household size. The tool will show you available plans and estimated premiums after APTC. Compare the lowest-cost Silver plan (which triggers the most favorable CSR cost-sharing if your income qualifies) and the lowest-cost Bronze plan.
Step 4: Check whether your current doctors are in-network on the marketplace plans you are considering. Most Florida carriers provide online provider directories. If network continuity is important, verify before switching.
Step 5: Compare the total out-of-pocket exposure. A COBRA plan with a $2,000 family deductible and $6,000 OOP max at $1,900/month versus a marketplace Silver plan with a $3,500 deductible and $8,700 OOP max at $450/month — the math almost always favors the marketplace for anyone who doesn't hit the deductible.
Both your COBRA election window and your ACA marketplace Special Enrollment Period begin on the same date: the day you lose employer coverage. You have 60 days for each. This means you do not have to choose immediately — you can spend time comparing options during the first 30 days.
If you elect COBRA, your coverage is retroactive to the day after your employer coverage ended, as long as you elect within the 60-day window and pay the premiums owed. This retroactive feature is COBRA's main practical advantage: if you wait and then get sick during the 60-day window, you can elect COBRA retroactively and your claims will be covered.
One important caveat: if you enroll in an ACA marketplace plan, your coverage typically starts on the first of the following month — there is a brief gap from your last day of employer coverage. If you need guaranteed zero-gap coverage (for example, you have a scheduled procedure), COBRA's retroactive election feature provides that assurance.
Is COBRA or ACA cheaper in Florida?
For most Floridians, ACA marketplace coverage is significantly cheaper than COBRA — often by hundreds of dollars per month. COBRA requires you to pay 102% of the full group premium (both the employee share and the employer share plus a 2% administrative fee). A typical Florida employer plan costs $600–$800/month for the employee alone, but the total premium including the employer's contribution is often $1,200–$2,200/month or more for a family. ACA marketplace plans offer premium tax credits based on your projected income that can reduce costs to $0–$150/month for many Florida residents.
Can I switch from COBRA to ACA mid-year?
Yes. Voluntarily dropping COBRA coverage is a qualifying life event that triggers a Special Enrollment Period on the ACA marketplace. You have 60 days from the date your COBRA coverage ends to enroll in a marketplace plan. Note that simply losing eligibility for COBRA (e.g., reaching the 18-month maximum) also qualifies. Strategically, some people elect COBRA to maintain continuity with their doctors during an ongoing treatment episode, then switch to a marketplace plan once that treatment concludes.
Does COBRA coverage count as qualifying coverage?
Yes. COBRA is considered qualifying health coverage under federal law, which means it counts as minimum essential coverage. While this is good for avoiding coverage gaps, it also means that if you are enrolled in COBRA, you are not eligible for ACA premium tax credits (APTC) for the same period — you must choose one or the other.
What if I already enrolled in COBRA — can I switch?
Yes, you can drop COBRA at any time. Dropping COBRA voluntarily triggers a Special Enrollment Period for the ACA marketplace — you have 60 days to enroll in a marketplace plan. The new marketplace plan will start on the first day of the following month (in most cases). You will not be able to retroactively receive marketplace subsidies for months you were on COBRA, so the sooner you switch if COBRA is unaffordable, the better.
A licensed Florida health insurance agent can compare your COBRA cost against available ACA marketplace plans side by side — and help you check whether your doctors are in-network. There's no cost to you.
