See the real cost of COBRA continuation coverage — your full premium plus the 2% fee — versus an ACA marketplace plan.

Short answer

COBRA Cost Calculator

$918Estimated monthly COBRA premium

Over 6 months COBRA costs $5,508. An ACA plan with a $400 subsidy would run about $500/mo — a potential saving of $2,508. Losing job coverage is a qualifying event for the marketplace, so compare before you elect.

How it's calculated: COBRA = 100% of the group premium plus a 2% admin fee — the jump from $250 to $918/mo surprises most people. Adjust the inputs below to recalculate for your own numbers.

Formula used

COBRA = (your share + employer share) × 1.02

On COBRA you pay the entire premium your employer used to subsidize, plus a 2% administration fee. That's why the typical bill jumps 3–5× overnight — and why an ACA plan with subsidies beats COBRA for most people under 65.

When COBRA is actually worth it

COBRA makes sense mid-deductible (progress carries over), when your doctors are out-of-network on marketplace plans, or when you need a 1–2 month bridge to new employer coverage. Otherwise, ACA plans with subsidies are usually dramatically cheaper.

  • You have 60 days to elect COBRA — it applies retroactively if you do.
  • ACA enrollment from job loss must happen within 60 days of losing coverage.
  • COBRA can be cheaper than ACA without a subsidy if you use little care and want the same network.

FAQ

Why is COBRA so expensive?

You see the full price for the first time: the average employer plan costs ~$750/mo single and ~$2,100/mo family, of which employers pay most. COBRA passes 100% plus a 2% fee to you.

Can I switch from COBRA to an ACA plan later?

Only during open enrollment or if you exhaust COBRA entirely — voluntarily dropping COBRA mid-term is NOT a qualifying event. Choose carefully at the start.

How long does COBRA last?

18 months after job loss or reduced hours, up to 36 months for qualifying family events (divorce, death of the employee, aging off a parent's plan).
