COBRA is almost always more expensive than a Marketplace plan, often significantly so. The reason is straightforward: COBRA requires you to pay the full cost of your former employer’s group plan, up to 102% of the total premium, while most people shopping on the Marketplace qualify for subsidies that dramatically reduce their monthly bill.
Why COBRA Costs So Much
When you had employer-sponsored insurance, your company likely covered 70% to 80% of the premium. You only saw the smaller portion deducted from your paycheck. Under COBRA, that employer contribution disappears. You’re suddenly responsible for the entire premium plus a 2% administrative fee.
For context, the average employer-sponsored family plan costs over $23,000 per year in total premiums. If your employer was covering 75% of that, you were paying around $480 a month. On COBRA, you’d owe the full amount: roughly $1,960 a month for the same coverage. Individual plans follow the same pattern at lower dollar amounts, but the sticker shock is real either way. That 102% figure catches many people off guard because they’ve never seen the true cost of their plan before.
How Marketplace Subsidies Change the Math
The Marketplace (also called the ACA exchange or Healthcare.gov) offers premium tax credits that lower your monthly cost based on household income. If your income falls between 100% and 400% of the federal poverty level, you qualify for these credits. For 2021 through 2025, Congress temporarily removed the 400% income cap, meaning even higher earners can get some help. Whether that expansion continues beyond 2025 depends on future legislation.
These subsidies can be substantial. Someone earning $35,000 a year might pay $100 to $200 per month for a silver-tier plan that would otherwise cost over $600. The subsidy is applied directly to your premium each month, so you never have to front the full amount and wait for a tax refund. For comparison, the average benchmark silver plan for a 40-year-old runs about $625 per month before subsidies. After subsidies, many people pay a fraction of that.
If your income is high enough that you wouldn’t qualify for meaningful subsidies, COBRA and an unsubsidized Marketplace plan may land in similar price ranges. In that narrow scenario, COBRA could even come out slightly ahead if your employer’s group plan negotiated particularly good rates. But for the majority of people who’ve just lost a job and seen their income drop, the Marketplace will be cheaper.
When COBRA Might Still Make Sense
Cost isn’t the only factor. There are a few situations where paying more for COBRA is worth considering:
- You’re mid-treatment. COBRA keeps you on the exact same plan with the same doctors and hospitals. Marketplace plans tend to have narrower provider networks. About 20% of Marketplace enrollees reported that a provider they needed wasn’t covered by their plan, compared to lower rates among people with employer coverage. If you’re in the middle of cancer treatment, a complicated pregnancy, or surgery recovery, continuity of care can outweigh cost savings.
- You’ve already hit your deductible. If you’ve spent thousands toward your annual deductible or out-of-pocket maximum, switching plans resets those numbers to zero. A few months of higher COBRA premiums might save you money overall if you’d otherwise face a fresh deductible on a new Marketplace plan.
- Your employer is subsidizing COBRA. Some severance packages include partial or full COBRA premium payments for a set period. If your former employer is covering the cost, COBRA is essentially free insurance, and you should use it for as long as that lasts.
Switching From COBRA to the Marketplace
Here’s a critical detail many people miss: you don’t have to choose one path and stick with it forever. But the rules for switching depend on timing.
When you first lose your job, you have 60 days to enroll in a Marketplace plan through a Special Enrollment Period. You also have 60 days to elect COBRA. These windows run simultaneously, so you can compare costs before committing. If you haven’t yet signed up for COBRA, you’re still eligible for Marketplace subsidies.
If you’ve already enrolled in COBRA, you can still switch to the Marketplace during the annual Open Enrollment Period (typically November through mid-January). Outside of Open Enrollment, your options are more limited. You generally qualify for a Special Enrollment Period to leave COBRA only if your employer stops contributing to your premiums or your COBRA coverage runs out entirely. Simply deciding COBRA is too expensive doesn’t trigger a mid-year switch on its own.
One important note: if you enroll in COBRA and want Marketplace subsidies, you need to drop your COBRA coverage before your Marketplace plan start date. You can’t collect subsidies while maintaining COBRA simultaneously.
How to Compare Your Actual Costs
The best way to answer this question for your specific situation is to get real numbers for both options. Your former employer’s HR department or benefits administrator can tell you the exact COBRA premium. Then visit Healthcare.gov (or your state’s exchange) and enter your expected income for the year to see what subsidized premiums look like.
When comparing, look beyond the monthly premium. Check the deductible, copays, and out-of-pocket maximum on each plan. A Marketplace bronze plan might have a low premium but a $7,000 deductible, which could cost you more overall than a higher-premium COBRA plan if you need frequent care. Silver plans on the Marketplace offer extra cost-sharing reductions for lower-income enrollees, making them particularly good value if you qualify.
Also factor in how long you’ll need coverage. COBRA lasts 18 months in most cases (36 months for certain qualifying events like divorce). If you expect to land a new job with benefits within a few months, a short stretch of COBRA to preserve your current doctors and deductible progress might be the practical choice, even at a higher monthly cost.
