Qualifying event and event date
Confirm what event created the COBRA right and when it occurred. Termination, reduction of hours, divorce, death, Medicare entitlement, or loss of dependent status can produce different rights and maximum periods.
A COBRA packet can be several pages long, but the decision usually turns on a small set of dates, people, plan elections, and costs. This guide shows where to look and uses anonymized figures from an actual 2025 election notice to demonstrate why the first bill may not be the long-term bill.
Start here: Do not upload or email an unredacted election notice casually. It can contain names, dependents, addresses, account numbers, QR codes, and portal registration credentials. Work from a redacted copy and verify every deadline directly with the plan administrator.

Eight fields to locate before deciding
Qualified beneficiaries
Check every person listed. Each qualified beneficiary can generally have an independent election right, so the household does not necessarily have to make one all-or-nothing choice.
First day of COBRA coverage
Identify the date continuation begins. Timely elected and paid COBRA is generally retroactive to the loss of coverage, which can make the initial bill include more than one month.
Last day to elect
Use the date printed on the notice. Federal plans generally must provide at least 60 days measured from the later of the notice date or the date coverage would otherwise end, but the administrator's notice should state the operational deadline.
Initial premium and grace period
Find both the amount and deadline. Federal COBRA plans generally must allow at least 45 days after the election for the first payment. Do not assume the plan will send another bill.
Ongoing premium and grace period
Find the normal monthly due date and payment method. Plans generally must provide a 30-day grace period for later monthly payments, but late payment can cause a temporary interruption or termination if the grace period expires.
Full premium versus amount owed
If the notice lists an employer subsidy, record the full premium, the employer contribution, and your amount owed separately. The amount owed today may be temporary.
Subsidy and COBRA end dates
Put both dates on the calendar. A subsidy can end before COBRA eligibility ends, causing a large increase while the underlying continuation right remains available.
A real offer where the first bill hid the long-term cost
The following figures came from an actual 2025 COBRA election notice supplied for educational analysis. Names, employer, administrator, insurer, plan identifiers, addresses, QR codes, credentials, and other identifying details are intentionally omitted. This is not presented as a Douglas Insurance Group client outcome.
$3,083.01Full monthly medical, dental, and vision premium
$2,054.88Temporary monthly employer subsidy
$1,028.13Temporary monthly amount owed by the household
The notice provided 18 months of continuation eligibility but only about 12 months of employer subsidy. If the family continued after the subsidy period, the listed monthly responsibility could rise to the full premium, subject to any plan-rate changes.
Scheduled monthly increase: $2,054.88 more per month - approximately a 199.9% increase over the subsidized amount owed.
The notice also showed a partial first-month bill and stated that projected premiums could change after elections or annual enrollment. That is why the actual notice and later administrator invoices remain controlling.
Compare the post-subsidy cost, not merely the first bill
| Item | During subsidy | After subsidy | What to verify |
|---|---|---|---|
| Full listed premium | $3,083.01/month | $3,083.01/month | Whether the plan rate changes |
| Employer contribution | $2,054.88/month | $0 scheduled | Exact subsidy end date and severance terms |
| Household amount owed | $1,028.13/month | $3,083.01/month | First full-cost invoice and payment deadline |
| Monthly increase | - | +$2,054.88 | Budget impact and available alternatives |
| Coverage design | Same underlying COBRA election | Same unless the plan changes | Benefits, network, formulary, deductible progress |
Marketplace timing matters: HealthCare.gov says having to pay the full COBRA cost because a former employer stops contributing may qualify someone for a Marketplace Special Enrollment Period. Do not cancel COBRA based on this sentence alone. Confirm current eligibility, enrollment timing, effective date, and first payment with the applicable Marketplace before ending existing coverage.
