How long do I have to elect COBRA?

Generally around 60 days from the later of your coverage ending or the date you receive the election notice. If you elect within that window, coverage is typically backdated to the day employer coverage ended and you pay the premiums for that period.

Is COBRA retroactive?

Generally yes. Electing within the window backdates coverage to when your employer plan ended, so the election period functions as a decision window rather than a gap. If nothing happens you have paid nothing; if something serious happens you can elect and the claim falls inside covered dates.

Is the marketplace cheaper than COBRA?

Often, because marketplace subsidies are based on expected income for the year rather than last year's salary — and income during a job loss is frequently much lower. People skip it because they remember a quote from a fully employed year, which is the wrong comparison.

Can I switch from COBRA to the marketplace later?

Not freely. Losing job-based coverage opens a special enrollment period, and exhausting COBRA at the end of its term generally does too — but voluntarily dropping it partway through usually does not, which can leave you waiting for open enrollment. Choose deliberately at the start.

What if my spouse has a plan at work?

Losing your own coverage is generally a qualifying event allowing you to join theirs, with its own short deadline. Ask their HR for the exact window as soon as you know your end date, because it is often shorter than the marketplace's.

COBRA or Marketplace: Health Insurance After Losing a Job

Almost nothing about losing a job is urgent. This is the exception.

There is a clock on health coverage, it is short, and the rules contain one piece of good news that is rarely explained.

The two doors

COBRA continues the exact plan you already had. Same doctors, same network, same deductible progress. The catch is the price: your employer stops paying its share, so you now pay the full premium plus up to a small administrative fee. For many people the number is three or four times what was coming out of their paycheck, and the shock is considerable.

The marketplace — healthcare.gov or your state's exchange — is separate coverage, with different networks, and with subsidies based on income.

Losing job-based coverage generally opens a special enrollment period of 60 days for the marketplace, and you can usually apply in the weeks before coverage ends rather than waiting.

The fact almost nobody is told

COBRA is retroactive.

You generally have around 60 days to elect it, and if you do, coverage is backdated to the day your employer coverage ended — you pay the premiums for that gap period.

Which means the 60 days is not dead time. It is a decision window in which you are, in effect, conditionally covered: if nothing happens, you have paid nothing. If something serious happens, you can elect COBRA and the claim falls inside covered dates.

That is a genuinely valuable feature and it is why panicking on day two is unnecessary. Use the window to compare properly.

Why the marketplace is often cheaper than people expect

Subsidies are based on expected income for the year, not last year's salary.

A woman whose income just stopped often has a far lower expected annual income than she is used to reporting — and subsidies can be substantial at those levels. People skip the marketplace because they remember a quote from a year when they were fully employed, which is the wrong comparison.

Run the numbers with your actual expected income for this year. It takes twenty minutes and it is frequently the difference between two plans that looked similar and two that are not remotely.

The trap in the middle

This one leaves people uninsured, so it is worth stating plainly.

Losing job-based coverage triggers a special enrollment period. Voluntarily dropping COBRA partway through generally does not. Exhausting COBRA at the end of its term usually does; quitting it in month four because the premiums became unbearable usually does not — and you may then be waiting for open enrollment.

So the choice between COBRA and marketplace is better made at the start, deliberately, than drifted into and abandoned later.

Things worth checking before choosing

Have you already met your deductible this year? Starting over mid-year on a new plan can outweigh a lower premium.
Is anyone mid-treatment? Continuity of specialist and network matters more than a monthly figure.
Are your prescriptions covered on the new plan's formulary? Check by name.
Could you join a spouse's or partner's plan? Loss of coverage is generally a qualifying event there too, with its own short window — ask their HR for the deadline.

What to do this week

Write down two dates: the day your coverage actually ends, and the day 60 days after it. Put both on a calendar. Then compare, once, properly.

That is the entire urgent list for a job loss. Everything else can wait.

What this article deliberately does not do

It does not tell you which to choose, what any plan will cost you, or what coverage you need. That depends on your health, your family, your state and your income.

What it does is make sure you know the window exists, that it is retroactive, and that the decision is better made once than drifted into twice.
