About this calculator

COBRA lets you keep employer health insurance for up to 18 months after job loss, but you pay full premium + 2% admin (typically $600-1500/mo for individual, $1500-3000 family). ACA marketplace plans are usually cheaper, especially with subsidies — premium tax credits cover much of cost for incomes under 400% federal poverty line ($60k single / $124k family in 2025). Special enrollment period triggered by job loss.
