Group vs Individual Health Insurance

Group vs individual health insurance is the decision that shows up at every job change: keep the employer plan through COBRA, join a new employer's plan, or buy on the marketplace. The three options price the same care very differently. This guide breaks down the COBRA math, when the marketplace wins, and how subsidies change the comparison — with the subsidy checker doing the heavy lifting.

Why group coverage is usually cheaper

Employer group plans spread risk across a large, healthy pool, so members pay average risk rather than individual risk. Employers typically cover 70% to 80% of the premium, and group underwriting is light — the sick and the healthy in the same office pay the same rate. That is why the identical plan is usually 30% to 50% cheaper through an employer than the unsubsidized individual equivalent.

• Group plans rarely ask about your health — individual plans can charge more for pre-existing conditions
• Employer subsidies are untaxed income, effectively boosting your paycheck
• Group plans bundle in services like wellness programs and mental health support
• The downside: your coverage, network, and price all change when you change jobs

The COBRA math

COBRA lets you keep your exact employer plan after leaving, but you pay the full premium — the employer's share disappears — plus a 2% administrative fee. For most people it is the most expensive option on the menu, even though it feels like the safest.

Employer plan total cost: $1,600/mo, employer pays $1,000
COBRA price: $1,600 + 2% admin = $1,632/mo
Marketplace silver plan: $1,150/mo
Income $85,000 (262% FPL for four): expected contribution ~$600/mo
Marketplace net: ~$600/mo — less than half the COBRA price
COBRA wins only if you have met your deductible or need specific doctors

Losing a job: your options in order

1. A new job with employer coverage, within 30 days of the event
2. A spouse's employer plan — a qualifying event opens a special enrollment window
3. Marketplace coverage with premium tax credits, within 60 days of losing coverage
4. COBRA, elected within 60 days and retroactive if you pay
5. Short-term limited plans as a last resort — they do not count as coverage for ACA purposes

The special enrollment window

Losing job-based coverage triggers a 60-day special enrollment period on the marketplace — no waiting for open enrollment. Your subsidy is calculated on your projected income for the full year, so a layoff that halves your income can produce a large credit. A family that earned $150,000 for half the year and $60,000 after a layoff has a blended income near $105,000 — and a subsidy sized to that, not to their old salary.

Decision checklist

• Check your deductible progress on the employer plan — COBRA preserves it
• Verify your doctors are in each network before comparing premiums
• Price the marketplace with your projected year income, not last year's
• Remember COBRA lasts 18 months and marketplace subsidies are income-based

The bottom line

Group coverage is the best deal in health insurance while you have it — the subsidy is hidden in the premium. Once it is gone, do not default to COBRA out of inertia: for most households, the marketplace with a premium tax credit beats COBRA by hundreds of dollars a month.
