COBRA lets you keep your old employer plan, but you pay the full premium plus a 2% fee — often $600–$700+ a month for one person, because your employer no longer pays its share. A 2026 Marketplace plan is frequently cheaper once your lower income qualifies you for a premium tax credit. The honest trade-off: switching resets your deductible to $0 mid-year, while COBRA keeps the deductible you've already met. Enter your numbers below to see the side-by-side total.

What this is and why it matters

When you leave a job, a federal law called COBRA usually lets you keep your exact employer health plan for up to 18 months — but you pay the whole premium yourself, both your old share and the part your employer used to cover. That's why COBRA feels so expensive: the coverage didn't change, but the bill did.

Your other option is a plan from the government's Health Insurance Marketplace. Losing job coverage opens a 60-day window to enroll, and because your income may have dropped, you might qualify for a subsidy that makes a Marketplace plan much cheaper than COBRA. This tool compares the two over the months you need, and walks you through the timing rules and trade-offs.

Your decision timeline after a job loss

The rules give you a real, usable window — but it closes. Here's the order of operations:

Key COBRA and Marketplace deadlines after losing job-based coverage.
WhatWhen
Special Enrollment Period to pick a Marketplace planUp to 60 days before and 60 days after coverage ends
Deadline to elect COBRA60 days from coverage loss or your election notice (whichever is later)
First COBRA payment dueUp to 45 days after you elect
Standard COBRA durationUp to 18 months

The "wait and see" strategy

Because COBRA can be elected retroactively to the day your coverage ended — any time within the 60-day window — and your first payment isn't due for up to 45 days after that, you have a hidden option. You can decline COBRA at first, stay technically uninsured for a few weeks while you shop, and if you have a medical event, elect COBRA retroactively to cover it. Many people use the window to enroll in a cheaper subsidized Marketplace plan instead, with COBRA as a fallback.

The trap: don't drop COBRA mid-year expecting to switch

This is the mistake that strands people on an expensive plan. Voluntarily dropping COBRA partway through is not a qualifying event for a Marketplace Special Enrollment Period — you'd generally have to wait until the next Open Enrollment to switch. (Letting COBRA run out after the full 18 months does qualify.) So the COBRA-vs-Marketplace choice is best made up front, during your initial 60-day window, not after you've already started COBRA.

Frequently asked questions

Is COBRA or the Marketplace cheaper?
It depends on your income. COBRA is the full group premium plus a 2% fee — often $600–$700+ for one person. A Marketplace plan can be much cheaper if your lower income now qualifies for a premium tax credit; if it doesn't, COBRA can be competitive and keeps your exact plan and met deductible.
How long do I have to decide?
60 days from your coverage loss (or election notice) to elect COBRA, and a 60-day Special Enrollment Period to choose a Marketplace plan. The clocks generally overlap, so you can compare first.
Can I decline COBRA and still get it later?
Effectively yes — COBRA is retroactive to your coverage-loss date within the 60-day window, and the first payment isn't due for up to 45 days after electing. That's a built-in "wait and see."
Does switching reset my deductible?
Yes — a new Marketplace plan resets your deductible and out-of-pocket max to $0 mid-year. COBRA keeps the same plan and your progress.
Can I drop COBRA mid-year and switch?
Usually not until Open Enrollment — voluntarily dropping COBRA isn't a qualifying event. Exhausting COBRA is. Decide up front.
Does being offered COBRA block a subsidy?
No. Being offered COBRA doesn't disqualify you from a premium tax credit; you can decline it and take a subsidized Marketplace plan.
