COBRA Legal Standard: Consolidated Omnibus Budget Reconciliation Act (COBRA) allows workers who lose benefits due to job loss, hours reductions, or transitions to continue employer plans. However, you generally lose all employer subsidies, which explains the high total premium.

The True Cost of a Job Transition

Losing or leaving a job is stressful enough, but navigating health insurance transitions can feel overwhelming. Many workers are shocked to discover how much their health insurance actually costs once they leave their job. While employed, companies subsidize a massive chunk of premium rates (often 70% to 80% or more). When you transition to COBRA, that safety net disappears. Our COBRA Health Insurance Cost Calculator provides immediate transparency, allowing you to estimate your new premium liabilities and evaluate whether a marketplace plan or spousal plan is a more cost-effective alternative.

Understanding the COBRA Cost Formula

Your new monthly COBRA premium is determined by aggregating the full premium cost and adding the administrative fee:

  • Base Premium: Employee Paycheck Contribution ($) + Employer Contribution ($) = Base Premium.
  • Administrative Surcharge: Base Premium × 2% (0.02) = Monthly Administrative Fee.
  • Total COBRA Payment: Base Premium + Administrative Surcharge = Total Estimated Monthly COBRA Liability.

Frequently Asked Questions

What is COBRA continuation coverage?

COBRA (Consolidated Omnibus Budget Reconciliation Act) is a federal law that gives workers and their families who lose their health benefits the right to choose to continue group health benefits provided by their group health plan for limited periods of time under certain circumstances (such as voluntary or involuntary job loss, reduction in hours worked, or transitions between jobs).

Why is COBRA health insurance so expensive?

When you are employed, your employer typically pays a massive portion of your health insurance premium (the employer subsidy), and you only pay a small portion out of your paycheck. Under COBRA, you are responsible for paying the entire cost of the premium (both your previous portion and the employer's portion) plus an additional administrative fee of up to 2%, causing your monthly expense to spike.

How long can I continue coverage under COBRA?

COBRA continuation coverage typically lasts for a maximum of 18 months for qualifying events like voluntary or involuntary termination of employment or reduction in hours. However, coverage can extend up to 29 or 36 months under specific circumstances, such as employee disability, divorce, or death.

How is the COBRA administrative fee calculated?

By law, the administrator of the group health plan can add a surcharge of up to 2% to the base premium cost to cover administrative expenses. Our calculator handles this by applying the 2% fee (e.g. on a base premium of $600, the fee is $12, resulting in a total monthly COBRA cost of $612). You can also customize this percentage in the calculator.

Is my premium data kept secure?

Yes. SnapTool performs all financial calculations, monthly premium aggregations, and lifetime cost projections locally inside your web browser. Your confidential health contributions and employer salary details are never saved or sent to external servers.
