COBRA vs a Marketplace Plan: Which Costs Less After You Leave a Job?

Your COBRA letter just arrived, and the number looks like a car payment. Here's why, and how to decide whether to keep it.

By the Upper Echelon Health advisory team · Updated October 25, 2026

Why COBRA costs so much

COBRA lets you keep your former employer's plan, usually for up to 18 months. It feels expensive because, while you were working, your employer was probably paying most of the premium. On COBRA you pay the whole thing, plus up to 2% for administration. Nothing changed about the plan. You're just seeing the full bill for the first time.

When COBRA is worth it

When a Marketplace plan wins

Note: you can't get a Marketplace tax credit for months you're enrolled in COBRA.

The 60-day election window

You generally have 60 days from your COBRA notice (or the date coverage ended, whichever is later) to elect it, and coverage is retroactive. That gives you time to shop. If you enroll in a Marketplace plan within your 60-day Special Enrollment Period and never need care during the gap, you may never pay for COBRA. If something happens, you can still elect COBRA and pay the premiums back to the start. Read your notice carefully and don't miss the deadline.

The timing trap

Once you elect COBRA, dropping it voluntarily in the middle of the year does not open a new Special Enrollment Period. Your windows to move to the Marketplace are:

  1. Within 60 days of losing your job coverage
  2. During Open Enrollment (starts November 1)
  3. When your COBRA coverage runs out completely

Frequently asked questions

Why is COBRA so expensive?

You're paying the full premium your employer used to share, plus up to 2%.

Can I switch from COBRA to a Marketplace plan?

Yes, within 60 days of losing job coverage, during Open Enrollment, or when COBRA ends. Not by dropping it mid-year.
