Health Insurance Between Jobs: What COBRA Really Costs

The health plan you paid $160 a month for actually costs about $760. Your employer was paying the rest, and COBRA hands you the whole bill plus a 2% fee — typically $500 to $850 a month for single coverage in 2026, and $1,400 to $2,350 for a family. On a $25,000 cushion, that single line item cuts roughly 38 days off your runway. Here is how to run the real numbers, and when the marketplace beats COBRA outright.

Most people budget for rent and groceries when they imagine life between jobs. Very few budget for the true price of their own health insurance, because they have never seen it. The paycheck deduction hides most of the cost. The layoff letter reveals it — usually a month after you have already made plans based on the wrong number.

Why COBRA is 102% of what you never saw

COBRA (the Consolidated Omnibus Budget Reconciliation Act) is not an insurance company. It is a federal rule that lets you keep your exact employer plan for up to 18 months after job loss. The catch is arithmetic: you now pay the entire premium — your share plus your employer's share — plus up to a 2% administrative fee.

KFF's employer health benefits survey puts the average total premium for single coverage at roughly $8,950 a year, with employers covering about $7,000 of it. That is the money you never saw on a paystub. Run it through the COBRA formula:

Your actual numbers will differ by plan and state, but the pattern does not: COBRA usually costs four to five times what your paycheck deduction was. Typical 2026 ranges land around $500–$850 per month for individual coverage and $1,400–$2,350 for family coverage. Employers with fewer than 20 employees are exempt from federal COBRA — some states run "mini-COBRA" rules instead, often with higher fees.

What $760 a month does to your runway

Here is the part the insurance guides skip. COBRA is not a standalone decision — it is a line item in your monthly burn, and your monthly burn decides how long your money lasts.

Thirty-eight days — more than a month of survival — is the real price of keeping the same plan. And going without coverage is not the alternative it looks like: one ambulance ride can cost more than a decade of premiums. The goal is not to skip insurance. It is to buy equivalent coverage for less, so the runway hit is as small as possible.

COBRA vs. the marketplace: the comparison that saves the most

Losing job-based coverage is a special enrollment event — you get 60 days to buy an ACA marketplace plan outside the normal open-enrollment window. For most people between jobs, this is where the money is:

Two 2026 specifics matter. First, the benchmark silver plan for a 40-year-old runs around $625 a month before subsidies — and with a layoff collapsing your income, many households qualify for credits that bring it to $0–$300. Second, the enhanced federal subsidies that ran from 2021 through 2025 expired at the end of 2025: the "subsidy cliff" is back, and households above 400% of the federal poverty level now pay full marketplace price. If that is you, COBRA's network continuity may be worth the premium after all.

When COBRA is actually the right call

• You are deep into your deductible. Met $2,000 of a $3,000 deductible in October? A marketplace plan resets it on January 1 anyway — COBRA carries your progress through year-end, which can outweigh the premium gap.
• You are mid-treatment. Surgery scheduled, pregnancy in progress, an oncologist who is out-of-network everywhere else: continuity of care is worth real money, and marketplace networks may not include your providers.
• You have a signed start date within a few months. Bridging a two-month gap is what COBRA does best — no new deductible, no new network, no marketplace enrollment to unwind later.
• Your income disqualifies you from subsidies. With the subsidy cliff back in 2026, higher-income households face full marketplace prices, and the premium difference versus COBRA shrinks to something continuity justifies.

The 60-day window most people don't know about

Here is a rule that changes the math for healthy people: COBRA is retroactive. You have 60 days from the election notice to decide, and after electing, 45 more days to pay the first premium. If nothing medical happens during that window, you can simply not elect — and you just navigated two months with $0 in premiums. If something happens on day 40, you elect retroactively, pay the back-premiums, and you were covered the whole time.

The three-step decision, in order

1. Get your real COBRA number — from the election notice, or W-2 Box 12 code DD ÷ 12 × 1.02.
2. Price the marketplace alternative at healthcare.gov using your projected search-period income (not last year's salary) — the subsidy math runs on the year you will actually report.
3. Add the winner to your monthly burn and recalculate your runway. The plan that wins the premium comparison is not always the one that wins the runway comparison — deductibles and your current health fold into that too.

Health coverage is usually the single biggest new line item between jobs — bigger than the gym you should cancel and the subscriptions this site's latte factor calculator will happily shame you for. Price it first, not last.
