COBRA vs. the marketplace after a job loss

Losing a job means losing employer health coverage, usually at the end of the month. You then face a fork in the road: COBRA, which continues your exact plan at full freight, or an ACA marketplace plan, which is new coverage that may come with big subsidies now that your income has dropped. The right answer depends on math most people never run — and the sticker shock of COBRA scares many into worse choices.

What COBRA actually is

COBRA lets you keep your employer plan for up to 18 months (sometimes 36), but you now pay the entire premium — your old share plus everything your employer was quietly covering — plus a 2% admin fee. Employers pay roughly 70–80% of premiums on average, so your $200/month plan can suddenly cost $700–$800 for an individual or $1,800+ for a family. Same doctors, same deductible progress, same everything — except the bill.

What the marketplace offers

Job loss is a qualifying event, opening a 60-day special enrollment period at HealthCare.gov (or your state's exchange). The crucial detail: premium tax credits are based on your estimated income for this calendar year — and if you just lost your job, that estimate may be low. A family that earned too much for subsidies in January can qualify for hundreds of dollars a month in credits after a mid-year layoff.

When COBRA wins

• You've already hit (or nearly hit) your deductible or out-of-pocket max this year — COBRA preserves that progress; a marketplace plan resets it to zero.
• You're mid-treatment with specialists you can't risk losing to a narrower network.
• Your year-to-date income is high enough that subsidies would be small anyway.
• You expect a new job with benefits within a month or two and just want continuity.
• Your employer subsidizes COBRA as part of a severance package — always check.

When the marketplace wins

• Your income for the calendar year will be modest — subsidies can make coverage dramatically cheaper than COBRA.
• You're healthy, met little of your deductible, and mainly need catastrophic protection.
• The job search could run longer than a few months — COBRA at $1,800/month burns severance fast.
• Your area's marketplace plans include your doctors (check the provider directory before enrolling).

Estimating income for subsidies

Marketplace subsidies use your modified adjusted gross income for the whole calendar year: months already worked, severance, unemployment benefits, spouse's income, and any expected new-job income. Guess honestly — subsidies reconcile on your tax return, so a lowball estimate becomes a repayment bill in April. Update your estimate on the exchange whenever your situation changes.

The bottom line

Get real quotes for both before deciding: your COBRA rate is in your election notice, and HealthCare.gov shows subsidized prices in about ten minutes. COBRA buys continuity; the marketplace usually buys a much lower price after a layoff. Use the 60-day window strategically, and never let a panic decision leave you uninsured.

The decision in one table

The hybrid play most people miss

The two options are not mutually exclusive across the year. A common optimal sequence for someone laid off in October who has met their deductible: ride the 60-day retroactive COBRA window through November and December (electing only if something happens), let the plan year close, then start a subsidized marketplace plan on January 1 when the deductible would have reset anyway. That sequence captures COBRA's free-look protection during the highest-value months and the marketplace's lower premiums for the long haul. The reverse works too: someone laid off in February with an empty deductible has almost nothing to preserve and should usually go straight to the exchange. The variable doing the work is how much deductible and out-of-pocket progress the calendar has banked.

Two final costs to model honestly. First, the family multiplier: COBRA prices scale per person, so covering a spouse and kids triples the pain — but nothing requires the whole family to make the same choice. A common split: the parent mid-treatment keeps COBRA for continuity while the healthy spouse and kids take a cheap marketplace plan. Second, the new-job wrinkle: most employer plans start on the first of the month after hire, sometimes after a 30-90 day waiting period. Ask the new employer about the waiting period before declining COBRA, because a six-week coverage gap with kids in the house is a risk no premium savings justifies. Bridge gaps deliberately — short-term coverage as a last resort is worse than either real option, so plan the handoff dates on a calendar the same week you get the separation notice. Ten minutes of date-mapping prevents both the coverage gap and the double-payment month — and it is the one part of a layoff you can fully control from the kitchen table.
