COBRA
0:00 / 0:00

In plain English

COBRA (Consolidated Omnibus Budget Reconciliation Act of 1985) lets former employees keep their employer-sponsored group health coverage for up to 18 months after leaving the job (longer in some circumstances, like disability or divorce). The catch: the former employee pays the full premium, employer-share plus employee-share, plus a 2% administrative fee. COBRA applies to most employers with 20 or more employees. Coverage starts on the day employer coverage would otherwise end; election must happen within 60 days of the qualifying event.

01Why it matters

COBRA is the safety net that prevents a gap in coverage between jobs, but the cost shock can be brutal. The employee's paycheck previously deducted only the employee-share; under COBRA the bill now includes the employer's share too, which is often two to three times higher than what showed up on prior pay stubs. For many ex-employees, comparing COBRA to ACA marketplace plans (which may qualify for income-based subsidies after a job loss) is a cost-saving step worth taking before defaulting to COBRA.

02The math, step by step

An employee leaving a job had a $650 per month payroll deduction for family health coverage. The employer was paying the rest, about $1,300 per month, for a total plan cost of $1,950 per month. Under COBRA, the former employee pays the full $1,950 plus 2% (about $39) = $1,989 per month. After 18 months, that is roughly $35,800 in premiums, paid directly to the plan administrator each month.

03What this is NOT

Do not confuse with the ACA marketplace

COBRA keeps the exact same plan, doctors, and deductible progress at full unsubsidized cost. The ACA marketplace (healthcare.gov) is a different set of plans, often with income-based premium subsidies that kick in after a job loss reduces income. Marketplace coverage is frequently cheaper than COBRA for someone with limited income between jobs; COBRA wins on continuity of care (same provider network, same accumulated deductible).
