Why the gap is the real danger
The risk is not just the cost of replacement cover, it is the window between your employer plan ending
and your new one starting. A few days uninsured can be uneventful, or it can be the days a hospital bill
or a prescription falls due. The whole point of this checklist is to close that window to zero, so cover
is continuous from your last covered day. That matters most if anyone on the plan has ongoing treatment
or regular medication, where even a short lapse can be costly or disruptive.
Before you resign
Price your options (US)
In the US, do not default to COBRA out of convenience. Price every route, because the cost difference is often large.
Replace cover (outside the US)
With public healthcare, your basic access does not depend on your job. What you replace is the private or supplementary cover your employer funded.
Before your last covered day
Mistakes that cause a lapse
Assuming an unconfirmed grace period
Coverage may end on your last day, not the end of the month. Get the exact date in writing rather than guessing.
Missing the enrollment window
US special enrollment is time-limited, typically 60 days. Miss it and you may be stuck waiting for the next open period.
Defaulting to COBRA
It is the easy option, but often the most expensive. A marketplace or partner plan can cost much less, so always compare.
Under-budgeting the cost
The premium your employer hid is now yours. Put the real figure in your budget so your runway is honest.

Frequently asked questions
How do I avoid a gap in health insurance when I quit?
Confirm the exact date your employer cover ends, in writing, and have a replacement plan arranged to start the same day with no gap. In the US that means electing COBRA or buying a marketplace plan within your special enrollment window; elsewhere it means replacing any private cover your employer provided. Never assume a grace period you have not confirmed.
Is COBRA or a marketplace plan better when quitting?
COBRA keeps your exact plan but you pay the full premium plus a fee, so it is often expensive. A marketplace plan may be cheaper, especially if your lower post-quit income qualifies you for subsidies, and a partner's employer plan can be cheaper still. The right move is to price all three before deciding rather than defaulting to COBRA.
How much should I budget for health insurance after quitting?
In the US, the only reliable figure is a real quote, because it varies widely by age, location, and plan, and it is frequently the single largest new cost after quitting. Get a COBRA and a marketplace quote, then add the real monthly figure to your post-quit budget so your runway reflects it.
