COBRA can cost far more than the old paycheck deduction because the worker may pay both the employee and former employer shares, plus up to a 2% administrative charge. Department of Labor guidance says the maximum is generally 102% of the plan’s total cost for similarly situated participants. Compare the full premium, not the old deduction.
A September 2026 HealthInsurance post described a COBRA premium rising from $610 to $950, while another layoff post said family COBRA cost almost as much as a mortgage. The hidden number is usually the former employer contribution.
Start here: a practical action plan
- Open the cited agency guidance and the actual employer plan document before relying on a deadline or benefit amount.
- Collect termination notices, coverage dates, premium quotes, account statements, tax forms, and dated confirmations.
- Replace the hypothetical figures with actual household costs, income, balances, dates, and plan terms.
- Submit the chosen action before the earliest applicable deadline and save proof that it was completed.
- Treating a forum answer or portal display as a substitute for the governing plan document or agency rule.
- Comparing one monthly price without including deductibles, tax treatment, deadlines, and the cost of a coverage gap.
- Spending a reserve or benefit before eligibility, payment, reimbursement, or tax treatment is confirmed.
Rebuild the premium from both shares
The paycheck showed only the employee contribution. Obtain the prior benefits statement or Form W-2 support showing employee and employer health-plan costs. Add both shares to estimate the full plan cost, then compare the COBRA notice.
Department of Labor guidance says COBRA can generally charge up to 102% of the total plan cost. The additional 2% is not 2% of the employee’s old deduction. It is calculated from the full cost, which is why the quote can look dramatically larger.
Worked example: a $280 payroll deduction becomes $918
Example: the employee paid $280 monthly and the employer paid $620. The full monthly cost was $900. At 102%, the maximum example COBRA premium is $900 x 1.02 = $918.
The increase from the paycheck deduction is $638 monthly. Over six months, COBRA premiums total $5,508, while the old employee deductions would have totaled $1,680. The difference is $3,828 because the employer subsidy ended and the administrative charge was added.
| Component | Calculation | Amount |
|---|---|---|
| Employee share | Old payroll deduction | $280 |
| Employer share | Benefits statement | $620 |
| Full plan cost | $280 + $620 | $900 |
| COBRA at 102% | $900 x 1.02 | $918 |
| Six-month COBRA | $918 x 6 | $5,508 |
Compare total annual exposure, not premium alone
COBRA can preserve the same network and accumulated deductible, which matters during active treatment. A Marketplace plan may have a lower premium but restart the deductible and change prescriptions or providers. A spouse plan may be cheaper yet have a short enrollment deadline.
Build one table with remaining-year premiums, deductible already met, expected care, out-of-pocket maximum, prescription costs, provider access, and start date. Include Marketplace premium-tax-credit eligibility based on estimated annual household income.
Question a quote that does not reconcile
A plan’s underlying cost can change, especially at a new premium cycle. Request the rate sheet, coverage tier, effective date, administrative percentage, and explanation of any retroactive increase. Compare family members and plan options carefully.
Do not withhold a required payment solely because the amount seems wrong. Pay under the notice when necessary to preserve coverage while disputing it, and keep written proof. If the administrator cannot explain the calculation, request the formal review path and contact EBSA for help.
- Find both employer and employee shares.
- Check the 102% calculation.
- Compare full-year exposure across plans.
- Document and challenge unexplained changes.
