COBRA Health Insurance: How It Works, What It Costs, and When to Use It
What COBRA Is
COBRA — the Consolidated Omnibus Budget Reconciliation Act — allows you to continue your employer’s group health insurance plan after leaving a job, being laid off, having your hours reduced, or experiencing other qualifying events. It gives you the right to keep the exact same plan, same network, same benefits, and same coverage you had as an employee. The catch is you pay the full premium — what you were paying plus what your employer was paying — plus a 2 percent administrative fee.
The Sticker Shock
Most employees pay 20 to 30 percent of their health insurance premium through payroll deductions. The employer covers the other 70 to 80 percent. Under COBRA, you pay 102 percent of the total premium. If your employer was paying $1,200 per month and you were paying $300, your COBRA premium is approximately $1,530 per month. For family coverage, COBRA premiums frequently exceed $2,000 per month.
This is the full cost of your health insurance that was hidden by the employer subsidy. Most people have no idea how expensive their coverage actually is until they see the COBRA price.
When COBRA Makes Sense
COBRA is valuable when you are mid-treatment with a provider who is in your employer plan’s network but might not be in marketplace plan networks. Switching plans mid-treatment can mean finding new doctors, new prior authorizations, and potential gaps in care. COBRA maintains continuity.
It makes sense when you have already met your deductible for the year. If you have met a $3,000 deductible and switch to a new plan, you start from zero. Staying on COBRA through year-end preserves your deductible progress and out-of-pocket accumulation.
It makes sense for short gaps. If you are starting a new job with benefits in two to three months, COBRA bridges the gap with continuous coverage and no network disruption.
When Marketplace Plans Are Cheaper
For most people, ACA marketplace plans are significantly cheaper than COBRA. Losing employer coverage is a qualifying life event that triggers a 60-day Special Enrollment Period on the marketplace. You do not have to wait for open enrollment. Marketplace plans with premium tax credits can cost $100 to $400 per month for the same individual who would pay $1,500+ for COBRA.
Compare COBRA cost against marketplace options immediately after losing coverage. Get marketplace quotes including any subsidy you qualify for. In the vast majority of cases, the marketplace is dramatically cheaper. COBRA’s advantage is continuity, not cost.
Timeline and Deadlines
You have 60 days from the qualifying event to elect COBRA. You do not have to decide immediately. Coverage is retroactive to the date of the qualifying event, so if you elect COBRA on day 59 and had a medical emergency on day 30, COBRA covers it retroactively.
This creates a strategic option: wait to elect COBRA. If nothing happens during the 60-day election period, you can enroll in a marketplace plan instead and never pay COBRA premiums. If something major happens medically during those 60 days, elect COBRA retroactively to cover it. This is not gaming the system — it is using the election period exactly as the law intends.
COBRA coverage lasts 18 months for job loss and reduction in hours. It lasts 36 months for other qualifying events like divorce or dependent aging out. After COBRA expires, you have another Special Enrollment Period to join a marketplace plan.
