This guide explains exactly how to compare COBRA and Marketplace coverage, what each costs, and which one fits which situation.

What COBRA Actually Costs

COBRA continuation coverage allows you to keep the exact health plan you had as an employee. The catch is the price.

Under federal law, employers can charge up to 102% of the full premium for COBRA. The 2% covers administrative costs. While employed, your employer was likely paying 70% to 80% of the premium. Under COBRA, you pay 100% of the premium plus the 2% administrative fee.

According to the Kaiser Family Foundation 2024 Employer Health Benefits Survey, the average annual premium for employer-sponsored health insurance was $8,951 for single coverage and $25,572 for family coverage. That translates to approximately:

Your specific premium will be on the COBRA election notice your employer or plan administrator sends within 45 days of your last day of work.

What Marketplace Insurance Actually Costs

Marketplace plans, sold through HealthCare.gov or a state-run exchange, are individual policies with prices that depend on your age, location, plan tier, and household income.

The 2025 Open Enrollment data from the Centers for Medicare and Medicaid Services (CMS) shows the median Marketplace premium before subsidies was approximately $477 per month for a Silver plan covering one adult.

The number that matters more than the list price is the premium tax credit. The American Rescue Plan extended through the Inflation Reduction Act caps Marketplace premiums at a percentage of household income through 2025:

For someone whose household income drops sharply because of a layoff, Marketplace coverage with subsidies often costs $0 to $250 per month, even at the Silver plan tier.

How to Compare the Two Plans

Step 1: Get your COBRA premium. The election notice from your employer or its plan administrator will list the exact monthly cost. If you have not received it within 14 days of your last day, contact HR.

Step 2: Get your Marketplace quote. Visit HealthCare.gov and complete the application. Use your projected annual income for the rest of the year, not your prior salary. If your layoff is permanent and you do not yet have new employment, your income for the rest of 2026 may be substantially lower than 2025.

Step 3: Compare on three dimensions, not just price.

The 60-Day Decision Strategy

You have 60 days to elect COBRA. You have 60 days from job loss to enroll in a Marketplace plan under the Special Enrollment Period.

Coverage from COBRA is retroactive to the day your prior coverage ended, even if you wait the full 60 days to enroll and pay. This creates a strategy: if you have no medical care needed in the first 30 to 45 days, you can wait, watch for any urgent medical needs, and decide.

If a major medical event occurs during the gap, you can elect COBRA retroactively and have it cover the event. If no event occurs, you can enroll in a Marketplace plan and skip the COBRA premium entirely.

This is not advice to skip coverage. Going uninsured is a serious financial risk. But the 60-day retroactive window is a real legal feature of COBRA and worth understanding.

State Mini-COBRA for Smaller Employers

Federal COBRA applies to employers with 20 or more employees. If your employer was smaller, federal COBRA does not apply, but most states have a mini-COBRA law for smaller groups.

Coverage periods, premium calculations, and notice requirements vary by state. Common features:

Common Mistakes That Cost Thousands

Mistake 1: Electing COBRA on the day you receive the notice without comparing Marketplace pricing first. Many laid-off workers default to COBRA out of familiarity and pay $400 to $700 more per month than they had to.

Mistake 2: Assuming you cannot get Marketplace subsidies because your prior salary was high. Subsidies are based on projected current-year income. After a layoff, your projected income usually drops significantly.

Mistake 3: Missing the 60-day Marketplace deadline. The Special Enrollment Period for job loss is exactly 60 days. After that, you cannot enroll until the next Open Enrollment Period in November.

Mistake 4: Waiting to compare until you decide on severance. Health coverage decisions and severance negotiations are independent. Get your Marketplace quote in the first week, regardless of how long the severance discussion takes.

Frequently Asked Questions

Can I switch from COBRA to Marketplace later?

Yes. Voluntary loss of COBRA does not trigger a Special Enrollment Period, but Open Enrollment in November allows you to switch. Involuntary loss of COBRA (such as your employer ending the plan) does trigger a Special Enrollment Period.

What if my COBRA election notice is late?

Federal law requires the notice within 45 days of the qualifying event (your last day). If 45 days pass without notice, contact your employer's HR and the plan administrator. The U.S. Department of Labor handles complaints about COBRA notice failures.

Are dental and vision included?

If your employer plan included dental or vision, COBRA can continue them. Marketplace dental is sold separately, and vision is typically not available on the Marketplace.

Can I keep COBRA for the full 18 months?

Yes. The standard period is 18 months, and certain qualifying events extend it to 29 or 36 months. You can also drop COBRA at any time and switch to other coverage.

The Math, in Practice

For a 45-year-old laid off from a tech company with a $180,000 salary, here is a representative example:

The decision is rarely as simple as "pick the cheaper one." Network, deductible, and continuity of care matter. But starting with the math is essential.
