How Does COBRA Insurance Work If You Quit Your Job?

If you quit your job, COBRA lets you keep your employer’s group health plan for up to 18 months, but you pay the full premium yourself plus a small administrative fee. That usually works out to over $700 a month for individual coverage, which is why many people compare it against a marketplace plan before electing. COBRA still wins in specific situations: mid-treatment, close to meeting your deductible, or attached to doctors who aren’t in other networks. Here is how the coverage, the deadlines, and the costs actually work when you’re the one who chose to leave.

Quitting Counts as a Qualifying Event

COBRA doesn’t distinguish between resigning and being laid off. Voluntary resignation is a qualifying event, and you get the same 18-month continuation right as someone who was terminated. The one exception is termination for “gross misconduct,” which federal law leaves undefined but which guidance describes as something well beyond ordinary performance or attendance problems.¹ Since you’re the one quitting, that exclusion isn’t your concern.

To be eligible, you had to be enrolled in the group health plan the day before you left. If you had already dropped your coverage, COBRA isn’t available.² A covered spouse and covered children are also qualified beneficiaries, and they can each elect COBRA independently. Your spouse can pick it up even if you don’t.

Federal COBRA only applies to private-sector employers who had at least 20 employees on more than half of their typical business days the previous year, along with state and local government plans.³ If your former employer was smaller than that, about 44 states have their own continuation laws, sometimes called “mini-COBRA,” with rules and durations that vary.

The Election Timeline

You have 60 days to decide whether to elect COBRA, counted from the later of the date you receive the election notice or the date your employer coverage would end.⁴ COBRA is never automatic. If you miss the 60-day window, the opportunity is gone.

Once you elect, coverage is retroactive to the day your employer plan ended, so there is no gap.⁵ Your first premium isn’t due until 45 days after you elect.²

That timeline creates a legitimate strategy. You can wait through most of the 60-day window to see whether you need expensive care. If nothing goes wrong, you may end up switching to a cheaper option and never electing COBRA at all. If something does go wrong, electing and paying the back premiums activates coverage retroactively. The risk is real: forget the deadline and you have nothing, and if you do need to activate, you owe all the missed premiums at once.

What COBRA Actually Costs

When you were employed, your company was probably paying 70 to 80 percent of your premium. Under COBRA, you pay the entire premium plus an administrative charge of up to 2 percent, for a total of 102 percent of the plan’s cost.⁶

Based on the most recent national employer survey data, average annual premiums for employer-sponsored coverage in 2025 were about $9,325 for individual plans and $26,993 for family plans. At 102 percent, that’s roughly $793 a month for one person or $2,294 a month for a family. Your actual number depends on your specific plan. High-deductible plans run less, and comprehensive PPO plans run more.

The rate is locked to your former employer’s group pricing, which can help if you have serious health conditions that would make individual coverage expensive or hard to underwrite. For a generally healthy person with moderate income, a marketplace plan with premium tax credits is almost always cheaper.

How Long the Coverage Lasts

The standard COBRA period after quitting is 18 months, measured from the day your employer coverage would have ended.² Your benefits stay identical to what active employees receive. If the employer changes its network, raises premiums, or adjusts covered services during that time, those changes apply to you too.

Disability Extension to 29 Months

If you or a covered family member is determined by the Social Security Administration to be disabled at any point during the first 60 days of COBRA coverage, the maximum period stretches from 18 months to 29 months, and it applies to everyone on the plan, not just the person with the disability determination.⁷ You have to notify the plan administrator of the SSA determination before the original 18 months run out. The cost also changes: during months 19 through 29, the plan can charge up to 150 percent of the premium instead of the usual 102 percent.⁶

Second Qualifying Events for Dependents

Dependents already on COBRA can extend their coverage to a total of 36 months if a second qualifying event occurs during the initial period. Second events include your death, divorce or legal separation, your becoming entitled to Medicare, or a dependent child aging out of the plan’s eligibility rules.⁸ The dependent has 60 days from the second event to notify the plan administrator. This extension is only for spouses and dependent children, not for you as the former employee.

Reasons COBRA Can End Early

Several things can cut your coverage short before you reach the maximum:³

Missing a premium. Each monthly payment has a 30-day grace period, but going past that permanently cancels your coverage, and the plan is not required to send reminders.
Becoming eligible for a new employer’s group health plan after you start a new job.
Becoming entitled to Medicare after electing COBRA.
Your former employer dropping its group health plan entirely.
Fraud or misconduct that would justify terminating any participant, such as submitting fraudulent claims.

If You’re Approaching 65, Don’t Rely on COBRA

This is the trap most people don’t know about. If you’re already Medicare-eligible or turn 65 around the time you quit, you have an 8-month Special Enrollment Period to sign up for Medicare Part B without a penalty, counted from when you stop working or lose employer coverage, whichever comes first.⁹ COBRA does not count as active employer coverage for this deadline. Your clock starts the day you leave the job.

Miss the 8-month window and you wait until the next general enrollment period (January through March), with coverage not starting until that July. You’ll also owe a late enrollment penalty of an extra 10 percent added to your Part B premium for every full 12-month period you could have enrolled and didn’t, and that penalty stays with you for life.¹⁰ A three-year delay means paying 30 percent more every month for as long as you have Medicare. If you’re near 65 when you quit, enroll in Medicare on time regardless of what you decide about COBRA.

Cheaper Options Worth Comparing First

COBRA’s real advantage is continuity: same doctors, same plan, same progress toward your deductible. For plenty of people who quit, though, the alternatives are less expensive and just as workable.

A Marketplace Plan

Losing job-based coverage opens a Special Enrollment Period on the federal or state marketplace, giving you 60 days to enroll outside the normal open enrollment window, with coverage usually starting the first of the following month.¹¹ Premium tax credits based on household income can bring the monthly cost far below COBRA, especially if your income dropped when you quit.¹² The enhanced tax credits from the Inflation Reduction Act expired at the start of 2026, so subsidies may be less generous than they were in recent years, but they’re still worth pricing out.

You can’t collect premium tax credits while enrolled in COBRA. To get subsidies, you have to decline COBRA or drop it before the marketplace plan starts.

Your Spouse’s Employer Plan

Your job loss is a qualifying life event for your spouse’s employer plan, and you typically have a 30-day window to enroll.¹³ Because their employer picks up part of the premium, this is almost always cheaper than COBRA. Check the network and deductible before switching.

Medicaid or CHIP

If quitting leaves you with little or no income, you may qualify for Medicaid, which provides comprehensive coverage at little to no cost. Children in families earning too much for Medicaid but too little to afford private coverage may qualify for the Children’s Health Insurance Program.¹⁴ Both accept applications year-round, and Medicaid coverage can begin immediately on approval. Eligibility rules vary by state.

When COBRA Is Actually the Right Call

Elect COBRA if you’re in the middle of expensive treatment, if you’ve already hit or come close to your annual deductible, or if your specific providers aren’t available on any marketplace plan you’d want. Everyone else should price out a marketplace plan first. If you’re healthy and between jobs for a short stretch, use the 60-day election window and the 45-day payment window as a safety net rather than paying premiums you may not need. And if Medicare is anywhere on your horizon, deal with that enrollment deadline before you spend any more time thinking about COBRA.
