How Much Is COBRA Insurance in California? The Monthly Cost, and How To Find Your Exact Number
Written and reviewed by Dick Tracy, licensed health insurance broker (NPN 20414610) · Published September 23, 2026
Quick answer How much is COBRA insurance in California? At California's average employer premiums, about $779 a month for one person, about $1,600 for employee-plus-one, and about $2,300 for a family. Federal COBRA costs up to 102% of the full premium: your old share, plus the share your employer was quietly paying, plus a 2% fee. If your employer had 2 to 19 employees, Cal-COBRA can charge up to 110%, so about $840, $1,726, and $2,480. Your exact number is on your election notice, and there are three ways to find it sooner.

I'm Dick Tracy, an independent health insurance broker licensed in California and 24 other states, working with 80+ carriers. I came from the healthcare side of this business, so there's no gag clause on me. Most people have never seen the real price of their employer plan until the COBRA notice lands. Here's the California math, the two sets of rules, and the traps.

Cost math: California average annual employer premiums for 2025 of $9,162 single, $18,827 employee-plus-one, and $27,057 family, divided by 12, times 1.02. Source: federal MEPS Insurance Component survey (AHRQ), published by KFF State Health Facts: single, employee-plus-one, family. The 102% rule: U.S. Department of Labor. The 110% Cal-COBRA cap: California Health and Safety Code 1366.26.
| Coverage tier | CA average plan cost per year | Federal COBRA per month (102%) | Cal-COBRA per month (110%) | 18 months at 102% | 36 months at 102% |
|---|---|---|---|---|---|
| One person | $9,162 | about $779 | about $840 | about $14,000 | about $28,000 |
| Employee-plus-one | $18,827 | about $1,600 | about $1,726 | about $28,800 | about $57,600 |
| Family | $27,057 | about $2,300 | about $2,480 | about $41,400 | about $82,800 |
These are averages. Your old plan could be richer or leaner than average, and your notice will have the real figure. The extension months past 18 can run at 110% on an insured plan, so the true 36-month total is usually a bit higher than the table.

Why does COBRA cost so much more than my paycheck deduction?
Because your employer was paying most of it. In the 2025 federal survey, the average California employer paid $7,647 of the $9,162 single premium, and the employee paid $1,515. That's roughly $126 a month out of your paycheck. On COBRA the same coverage is about $779 a month. Same plan, same card, about 6.2 times the price, because the employer's share is now yours, plus the 2% fee. For a family, the average employee share was $7,847 a year, about $654 a month, and the COBRA bill is about $2,300. The math doesn't math for most healthy people.
Here's the part that surprises New Yorkers who move west, and Californians who assume everything costs more here. California's employer plans run close to the national average: $9,162 for single coverage against $9,025 nationally, about 1.5% higher, and $27,057 for a family against $26,281, about 3% higher. New York runs about 21% above the national average for single coverage. In California the shock is not the state. It's the employer share you never saw.
Three ways to find your exact COBRA price
- Ask HR for the total premium. Ask for the full monthly premium for your tier, both shares combined, and multiply by 1.02. If your employer has 2 to 19 employees and you'll be on Cal-COBRA, multiply by 1.10 instead.
- Check your W-2, Box 12, code DD. The IRS says that figure is the total cost of your employer health coverage, both the employer and employee portions. Divide by 12, multiply by 1.02, and you have a close estimate. Employers filing fewer than 250 W-2s aren't required to report it, so a small employer may leave it blank. Source: IRS.
- Read the election notice. It states the exact premium and the deadline. That's the number that counts.
The California rules that change the bill
Two sets of rules, two prices. Federal COBRA applies to employers with 20 or more employees and caps the premium at 102% of the plan's full cost. Cal-COBRA covers insured plans at employers with 2 to 19 employees, so a 6-person shop in Fresno has to offer it too, and the cap is 110% of the group rate. Same coverage, a slightly bigger bill. Sources: U.S. Department of Labor and California Department of Insurance.
36 months is possible, but not free. Federal COBRA gives 18 months after a job loss. On an insured plan, California law then requires the health plan or insurer to offer you more time, up to 36 months counted from the day your COBRA began, under Health and Safety Code 1366.29. The extension months can run at up to 110%. At the family average, 36 months is over $82,000 in premiums before that bump. Longer isn't cheaper.
Self-funded plans don't get the California extras. The Department of Insurance says it flatly: self-insured plans are not eligible for Cal-COBRA. Big employers often self-fund. Ask HR, in writing, whether your plan is insured or self-funded before you count on 36 months.
The clock. Under federal COBRA you have 60 days to elect and then 45 days after electing to make the first payment, and coverage is retroactive to the day your job plan ended. That first payment can cover more than one month, so budget for it. One more trap: if you start COBRA and later just stop paying, that does not open a special enrollment window elsewhere. Decide on purpose, not by default. The full head-to-head on the two programs, deadlines, and the extension is on my COBRA vs Cal-COBRA page.
Is COBRA worth that price in California?
Sometimes, and I'll say it plainly. If you're mid-treatment, pregnant, scheduled for surgery, or you've already met a big deductible this year, the continuity is worth the money. Same if you had a serious diagnosis in the last few years. For a healthy person or family, COBRA is usually the most expensive door in the hallway, because it's one plan at one price and you can't shop it.
California gives healthy people a door most states don't. Private carriers here can medically underwrite, which means a healthy person is priced on their own health instead of the sickest people in a pool, often with a true PPO network. There's also the pre-established ERISA group plan: group rates, a policy you own and take to the next job. Covered California is one more tool, and I'll explain it honestly: subsidies can be real money at lower incomes, but you're guessing at next year's income, the networks tend to be narrow, and a wrong guess gets settled at tax time. Use the 60 days to price every door side by side. Pack the parachute before the plane goes down.
Common questions about COBRA cost in California
How much is COBRA insurance in California?
At California's average employer premiums, federal COBRA runs about $779 a month for one person, about $1,600 a month for employee-plus-one, and about $2,300 a month for a family. COBRA is priced at up to 102% of the full premium, meaning your share plus the share your employer was paying, plus a 2% administration fee. The averages come from the federal MEPS Insurance Component survey for 2025 as published by KFF: $9,162 a year single, $18,827 employee-plus-one, and $27,057 family in California. Cal-COBRA, for employers with 2 to 19 employees, can charge up to 110%, which is about $840, $1,726, and $2,480 a month at the same averages. Your exact price is printed on your election notice.
Why does COBRA cost so much more than what came out of my paycheck?
Because your employer was paying most of the bill. In the 2025 federal MEPS survey, the average California employer paid $7,647 of the $9,162 single premium and the employee paid $1,515, about $126 a month. On COBRA the same coverage costs about $779 a month, roughly 6.2 times as much, because the employer's share is now yours plus a 2% fee. For family coverage the average employee share was $7,847 a year, about $654 a month, against about $2,300 a month on COBRA.
Is COBRA more expensive in California than in other states?
Only slightly. In the 2025 federal MEPS survey, the average California employer plan cost $9,162 a year for single coverage against $9,025 nationally, about 1.5% higher. Family coverage averaged $27,057 in California against $26,281 nationally, about 3% higher. The shock in a California COBRA bill is not the state, it is the employer share you never saw. New York, by comparison, runs about 21% above the national average for single coverage.
How do I find my exact COBRA cost before the notice arrives?
Three places. First, ask HR or the benefits administrator for the total monthly premium for your coverage tier and multiply by 1.02, or by 1.10 if your employer has 2 to 19 employees and you will be on Cal-COBRA. Second, check Box 12 of your last W-2 for code DD, which the IRS says shows the total cost of your employer health coverage, both the employer and employee portions combined; divide by 12 and multiply by 1.02. Employers filing fewer than 250 W-2s are not required to report it, so a small employer may leave it blank. Third, wait for the election notice, which states the exact premium.
How much does COBRA cost for 18 months or 36 months in California?
At the 2025 California averages and the federal 102% rate, 18 months of COBRA totals about $14,000 for one person, about $28,800 for employee-plus-one, and about $41,400 for a family. Thirty-six months roughly doubles that: about $28,000, $57,600, and $82,800. Federal COBRA lasts 18 months after a job loss, and on an insured plan California law lets you extend to 36 months total from the date COBRA began, at up to 110% of the group rate for the extension months.
Does COBRA apply if my California employer has fewer than 20 employees?
Federal COBRA does not, but Cal-COBRA does. Federal COBRA applies to employers with 20 or more employees. California's Cal-COBRA covers insured plans at employers with 2 to 19 employees, lasts up to 36 months, and can charge up to 110% of the group rate under California Health and Safety Code section 1366.26. It does not apply to self-funded plans. The California Department of Insurance says plainly that self-insured plans are not eligible.
Is there anything cheaper than COBRA in California?
Often, yes, for healthy people. COBRA is one plan at one price with no shopping. California allows medically underwritten private plans, so a healthy person or family can often be priced on their own health instead of the whole group, or merge into a pre-established ERISA group plan with group rates and a true PPO network they own and keep through the next job. COBRA is still the right call if you are mid-treatment, pregnant, have already met a large deductible this year, or had a serious diagnosis recently. An independent broker can price the options side by side at no cost.
Thirty minutes, no fee, no hard sell. If COBRA is the right move for you, I'll say so.
