COBRA vs. ACA Marketplace: The Real Cost Comparison After Job Loss
When you lose a job, you have 60 days to decide between COBRA and the ACA marketplace. Most people default to COBRA because it's familiar and continues existing coverage. But COBRA often costs 3–5× what an ACA plan costs after subsidies — especially if your income drops. This decision is worth $5,000–$15,000/year. Here's how to compare.
What COBRA actually costs
COBRA allows you to continue your employer-sponsored health insurance after job loss — but you pay the full premium (your share + the employer's share) plus a 2% administrative fee. Most people have no idea how much their employer was subsidizing their coverage until they see the COBRA bill.
| Coverage | You Paid on Job | COBRA Monthly Cost | Annual Difference |
|---|---|---|---|
| Individual (common plan) | $250/mo | $722/mo | +$5,664/yr |
| Employee + spouse | $550/mo | $1,580/mo | +$12,360/yr |
| Family (2 kids) | $700/mo | $2,050/mo | +$16,200/yr |
When ACA marketplace beats COBRA
ACA subsidies (premium tax credits) are based on your projected annual income for the year. After job loss, if your income drops significantly, you may qualify for substantial subsidies that make an ACA plan dramatically cheaper than COBRA.
ACA subsidy eligibility (2026): You qualify for subsidies if your projected income is between 100% and 400% of the Federal Poverty Level. Subsidies phase out above ~$58,320 (individual) or $120,000 (family of 4). At lower income levels, the savings are massive:
| Annual Income | FPL % | ACA Silver Premium Cap | ACA Monthly Premium (est.) | vs. COBRA |
|---|---|---|---|---|
| $25,000 | ~195% | 6.0% of income | ~$125/mo | Save $597/mo vs. COBRA |
| $40,000 | ~311% | 9.0% of income | ~$300/mo | Save $422/mo vs. COBRA |
| $55,000 | ~427% | Full unsubsidized | ~$550/mo | Save $172/mo vs. COBRA |
| $70,000+ | Full premium | Unsubsidized | $500–$700/mo | Similar to COBRA |
The key insight: Estimate your income for the rest of the year — unemployment benefits + severance + any freelance income. If you expect to earn under $55,000 as an individual this year, ACA will almost certainly be cheaper than COBRA. Log in to healthcare.gov and run the numbers with your actual estimated income before making any decision.
When COBRA makes sense
- You're in the middle of expensive treatment — surgeries, chemo, ongoing specialist care. COBRA maintains your exact provider network and plan, with no disruption. Switching ACA plans mid-treatment can mean new deductibles and potential network breaks.
- You expect to get a new job within 1–3 months and want seamless continuity
- Your income won't drop significantly (no ACA subsidy advantage)
- You're near the end of the year and have met your COBRA plan's out-of-pocket maximum
The COBRA backdating trick (rarely known)
You have 60 days to elect COBRA — but COBRA coverage is retroactive to the date your employer coverage ended. This means you can wait up to 60 days to decide. If you stay healthy, don't elect. If you have a medical event within those 60 days, elect COBRA retroactively and pay the back premiums. You get the protection of COBRA without the ongoing cost if you don't need it. Risk: you must pay all premiums if you retroactively elect.
