Navigating the COBRA vs. ACA Special Enrollment Decision

When an employee departs a company, the federal Consolidated Omnibus Budget Reconciliation Act (COBRA) allows them to temporarily continue their existing group health plan. However, because employers typically subsidize 70% to 85% of employee healthcare costs, paying the full 100% premium plus a 2% administrative fee creates severe "sticker shock" for job seekers.

1. The 60-Day Qualifying Life Event (QLE) Window

Losing employer-sponsored health insurance triggers an automatic 60-day Special Enrollment Period (SEP) on HealthCare.gov or state exchanges. Because post-layoff household income is frequently lower, individuals qualify for significant Advance Premium Tax Credits (APTC), drastically reducing monthly expenses compared to COBRA.

2. When Does Keeping COBRA Make Sense?

COBRA is typically mathematically superior only when you have already satisfied a large annual deductible (e.g., $3,000+) late in the calendar year, are currently undergoing active medical treatments with specific out-of-network specialists, or expect to secure a new job with benefits in less than 60 days.

Frequently Asked Questions

Can I drop COBRA and switch to the ACA Marketplace later?

Only during the annual Open Enrollment Period (Nov 1 – Jan 15) or if your COBRA period expires completely (18 months). Voluntarily cancelling COBRA mid-year does NOT qualify as a Special Enrollment Period.

Are my salary and transition numbers stored anywhere?

Never. All calculations execute 100% locally in your device's browser memory (RAM).
