COBRA Insurance Cost: Why It's So Expensive (The 102% Rule)
The federal rule behind why COBRA feels like sticker shock right after a job loss — plus how to calculate your real number and cheaper alternatives.
COBRA lets you keep your exact employer health plan after leaving a job, but you pay the full premium — your old payroll deduction plus the part your employer used to cover — plus up to a 2% admin fee. That's the "102% rule," and it's why COBRA bills often come as a shock: a $150/month paycheck deduction can become a $700+/month bill once the employer's hidden share is added back in.

Losing a job is stressful enough without a health insurance bill that's suddenly 4-5x what you were used to seeing come out of your paycheck. That jump isn't an accident or a penalty — it's the direct, legally-defined result of one thing disappearing the moment you leave: your employer's share of the premium. Here's exactly how that math works, and what your realistic alternatives are.
The 102% Rule
The Consolidated Omnibus Budget Reconciliation Act of 1985 — COBRA — gives eligible employees and their dependents the right to continue their exact group health plan after a qualifying event like job loss, reduced hours, divorce, or a dependent aging out. The law also sets the maximum price the plan administrator can charge:
That extra 2% is the only markup the law allows, meant to cover the administrative cost of running continuation coverage. Everything else in the jump you feel is simply the employer's contribution — often 60-80% of the total premium for employer-sponsored plans — no longer being subsidized.
Worked Example
| Component | Amount |
|---|---|
| Your old monthly payroll deduction | $150 |
| Employer's old monthly contribution | $550 |
| Full group premium | $700 |
| Plus 2% admin fee | $14 |
| Your COBRA premium | $714/month |
That's roughly a $564/month increase from what this person was used to seeing deducted — not because COBRA itself is overpriced, but because $550/month of employer subsidy simply vanished.

Is There a Cheaper Option?
COBRA
- Keeps your exact plan, doctors, and network
- No new waiting period or pre-existing condition exclusion
- Full, unsubsidized premium — often the most expensive option
ACA Marketplace plan
- Different plan and network — may not match your current doctors
- Can qualify for income-based premium tax credits
- Often cheaper, especially at lower post-job-loss income
Because losing job-based coverage is itself a qualifying event, it opens a Special Enrollment Period for ACA Marketplace plans — you're not required to stick with COBRA for the full 18 months if a subsidized Marketplace plan works out cheaper. Run your income through our health insurance subsidy calculator to see whether you'd qualify for a premium tax credit that changes the comparison.
Worth knowing: COBRA eligibility typically runs 18 months after job loss, but certain qualifying events — divorce, or a dependent aging out of the plan — can extend it up to 36 months. Check your COBRA election notice for your specific eligibility window.
Frequently Asked Questions
Why is COBRA insurance so expensive?
Because you go from paying just your share of the premium to paying the full premium — both your old payroll deduction and the part your employer used to cover — plus up to a 2% administrative surcharge. It's not that COBRA is priced differently, it's that you stop getting the employer subsidy.
What is the COBRA 102% rule?
Federal law (COBRA, enacted 1985) caps what employers can charge continuing coverage participants at 102% of the plan's full premium — 100% of the actual cost plus a 2% administrative fee, the only markup allowed.
How long does COBRA coverage last?
Typically 18 months after a qualifying event like job loss or reduced hours. Certain events — such as divorce or a dependent aging out of the plan — can extend eligibility up to 36 months.
Is COBRA cheaper than an ACA Marketplace plan?
Often not — COBRA keeps your exact former plan and network but at full, unsubsidized cost, while an ACA Marketplace plan may qualify for premium tax credits based on your income after job loss, sometimes making it meaningfully cheaper even with a different network.
Can I switch from COBRA to a Marketplace plan later?
Yes — losing job-based coverage (including COBRA running out) is itself a qualifying life event that opens a Special Enrollment Period for ACA Marketplace coverage, so you're not locked into COBRA for its full duration if a cheaper option appears.
Does COBRA cover pre-existing conditions immediately?
Yes — COBRA continues your exact same group health plan with no new waiting period or pre-existing condition exclusion, since it's a continuation of coverage you already had, not a new policy.
