COBRA vs ACA Marketplace — when each is the right choice

6 min read · Updated May 2026 · By licensed SilverEdge advisors

Lost your job-based health coverage? You have a 60-day window to either elect COBRA or enroll in an ACA Marketplace plan. They're very different products. For most people, ACA is significantly cheaper. Here's how to choose.

Key takeaways

  • COBRA lets you keep your exact job-based plan for up to 18-36 months — but you pay the full premium plus 2% admin fee.
  • ACA Marketplace qualifies you for premium subsidies based on your new income, often making it dramatically cheaper.
  • Switch: You can switch from COBRA to ACA at next Open Enrollment (or sooner if your COBRA runs out).
  • The math: For most middle-income job losers, ACA is 40-70% cheaper than COBRA after subsidies.

How COBRA works

COBRA (Consolidated Omnibus Budget Reconciliation Act of 1985) lets you continue your former employer's group health plan after losing job-based coverage. Key facts:

  • Same plan, same network: You keep the exact same coverage, doctors, deductibles, and prescription tiers.
  • You pay the full premium: What your employer used to pay PLUS what you used to pay PLUS 2% admin fee. Often 200-400% of what you previously paid.
  • Duration: Up to 18 months for most events (job loss, reduced hours). Up to 36 months for divorce, death of covered employee, or losing dependent status.
  • Election deadline: 60 days from the loss-of-coverage notice OR from coverage end date — whichever is later.

How ACA Marketplace works after job loss

Losing employer coverage triggers a Special Enrollment Period (SEP) to enroll in an ACA Marketplace plan. Key facts:

  • Different plans, possibly different networks: You're choosing from Marketplace plans, not your old employer plan.
  • You pay your share of premium based on income: If your forecast income for the year is lower than employed income, you may qualify for premium tax credits and cost-sharing reductions.
  • Duration: Indefinite — ACA plans renew annually; you can keep coverage as long as you want.
  • Election deadline: 60 days from loss of coverage.

The math — a worked example

Imagine a 45-year-old earning $90,000/year who just lost her job. She's getting severance for 3 months and expects to find new work in 4-6 months. Her old job-based plan was a $600/month family premium ($200 her share, $400 employer).

COBRA option: $600/month employer premium + 2% admin = $612/month. For 6 months: $3,672. She keeps her doctors and her prescription tiers.

ACA option: Forecast income of $40,000 for the year (severance + projected unemployment + part-year new job = much less than $90K full year). At ~210% FPL, she qualifies for ~$700/month subsidy. A comparable Silver plan costing $700/month becomes ~$0/month after subsidy. For 6 months: ~$0.

Difference: ~$3,672 saved by choosing ACA. Network may be different — she'd want to verify her doctors are in the ACA plan's network before committing.

When COBRA actually wins

COBRA is the right choice when:

  • You have ongoing care with specific specialists who are in your current network but not in nearby ACA plans — e.g., mid-cancer-treatment.
  • You've already met your deductible for the year and have major procedures coming up — starting fresh with an ACA plan resets the deductible.
  • Your new job starts in <2-3 months with new coverage starting then — the short-term continuity may not be worth switching plans.
  • You have FSA money tied to the employer plan — some FSA arrangements only work with COBRA continuation.

The hybrid strategy: short-term COBRA → ACA

A common play: elect COBRA for 1-3 months to keep continuity through a known procedure or until a specialist appointment, then switch to ACA at the next opportunity (Open Enrollment if you can wait, or if your job-loss SEP is still open).

Note: Voluntarily dropping COBRA does not trigger an SEP for ACA. The original loss-of-employer-coverage SEP gives you 60 days from the original coverage-loss date — not from when COBRA ends. So if you're going to do hybrid, calculate carefully so your ACA enrollment lands within the 60-day window.

EXCEPTION: COBRA naturally running out (e.g., reaching the 18-month limit) DOES trigger an SEP.

Common questions

Is COBRA cheaper than the ACA Marketplace?
Usually no. COBRA charges 100% of the employer's group rate plus a 2% admin fee — typically $600–$2,000/month for a family. With ACA subsidies, marketplace plans average $200–$600/month for the same household.
How long do I have to enroll in ACA after losing my job?
60 days from the date you lose employer coverage. This is a Special Enrollment Period (SEP) — you must enroll within 60 days or wait until the next Open Enrollment Period (Nov 1–Jan 15).
Can I switch from COBRA to the ACA Marketplace?
Voluntarily dropping COBRA is not a qualifying life event — you'd have to wait for Open Enrollment. But if your COBRA coverage runs out (typically after 18 months), that triggers a 60-day SEP for marketplace enrollment.
Does COBRA count as 'minimum essential coverage'?
Yes. COBRA satisfies ACA's individual mandate (where state mandates exist) and prevents gaps. But choosing COBRA doesn't disqualify you from getting ACA subsidies later if you switch during Open Enrollment.
