Florida COBRA vs ACA Marketplace — Which Is Cheaper When You Lose a Job?

When a job ends and employer health coverage goes with it, most people assume COBRA is the only option — just keep the same plan and pay a bit more. In reality, COBRA is often significantly more expensive than getting a new plan through the ACA marketplace. Here's a clear framework for making this decision in Florida.

How COBRA Works

COBRA lets you continue your exact employer plan — same network, same doctors, same deductibles — after your job ends. The catch: you now pay the full premium. That means your share plus your employer's share, plus a 2% administrative fee. Most people don't know how much their employer was contributing until they see the COBRA bill.

In Florida, typical COBRA costs look like this:

• Single coverage: $600–$900/month (full group premium + 2%)
• Family coverage: $1,700–$2,600/month

If your employer was paying $500/month toward your premium and you were paying $150, your COBRA payment jumps to roughly $663/month. That $513/month difference is the real cost of COBRA — the price of continuity.

How the ACA Marketplace Works After Job Loss

Losing employer-sponsored health coverage is a qualifying life event that triggers a 60-day Special Enrollment Period (SEP) on the ACA marketplace. You don't have to wait for open enrollment. You can shop, compare, and enroll in a new plan starting the day your employer coverage ends.

With enhanced subsidies (extended through 2025 and still in effect for 2026), marketplace premiums can be dramatically lower than COBRA — especially if your income has dropped since leaving work. A single person earning $35,000/year might pay $0–$80/month for a Silver plan after the premium tax credit. A family of four at $60,000/year could pay $150–$300/month.

How to Calculate Which Is Cheaper

The comparison isn't just about monthly premiums — it's about total out-of-pocket cost. Here's the math to run:

1. Get your full COBRA premium — your HR department or benefits administrator will send this. It's the combined employer + employee cost + 2%.
2. Estimate your annual income — if you're between jobs, project forward. Unemployment benefits count as income for subsidy purposes; severance typically counts too.
3. Check marketplace plan costs — use Florida Plan Finder or HealthCare.gov's preview tool to see plan options and estimated subsidies at your income level.
4. Compare deductibles — if you've already met your deductible on your employer plan mid-year, COBRA preserves that. A new marketplace plan resets your deductible to zero.

When COBRA Makes More Sense

COBRA wins in specific situations:

• You're mid-year and have already met your deductible or out-of-pocket maximum on your employer plan
• You're in active cancer treatment or ongoing specialist care and your providers are only in your current plan's network
• Your income is high enough that marketplace subsidies are minimal or zero
• You're within a few months of turning 65 and transitioning to Medicare — short-term COBRA bridge makes sense
• You expect to return to employer coverage quickly (within 1–3 months) through a new job

When the Marketplace Makes More Sense

The marketplace wins in more situations than most people expect:

• Your income has dropped and you qualify for meaningful ACA subsidies
• You haven't met your deductible yet this year (so there's no sunk cost to preserve)
• You need to reduce your monthly premium spend significantly
• You don't have ongoing specialist care tied to a narrow employer network
• You're starting a new job within 3–4 months but want lower premiums in the meantime

Florida Mini-COBRA: Small Employer Rules

Federal COBRA applies to employers with 20 or more employees. If you worked for a small Florida employer with 2–19 employees, you're covered by Florida's mini-COBRA law instead. Florida mini-COBRA provides the same 18-month continuation period with the same 102% premium rule. You'll receive a notice from your employer's insurance carrier within 14 days of losing coverage.

The Timing Trap to Avoid

Here's the most important thing to understand: if you elect a marketplace plan, your COBRA SEP clock doesn't stop — it continues running. However, you cannot be enrolled in both plans simultaneously for the same coverage period. Once you're actively enrolled in a marketplace plan, COBRA enrollment becomes moot. Conversely, if you elect COBRA first, you can still enroll in a marketplace plan during open enrollment or when COBRA eventually expires (expiration is an SEP-qualifying event).

The practical strategy: don't elect COBRA immediately. Take a few days to price out marketplace options first. If marketplace plans are significantly cheaper and you don't have an in-progress deductible to protect, the choice is clear. If COBRA looks better, elect it — it's retroactive, so no care will go uncovered during the evaluation window.
