The Consolidated Omnibus Budget Reconciliation Act (COBRA) is a federal law that allows eligible employees and their dependents to continue their group health insurance coverage for a limited time after leaving a job, experiencing a reduction in hours, or due to other qualifying events. This continuation of coverage is typically the same plan they had while employed.
How are COBRA Rates Calculated?
When you elect COBRA coverage, you are generally responsible for the entire premium, plus a small administrative fee. The law allows employers to charge you up to 102% of the total premium cost. This 102% is made up of:
The full premium: This is the total cost of the health insurance plan, which includes the portion you and your employer used to pay.
The employer's portion: Previously, your employer subsidized a portion of your health insurance premium. Under COBRA, you will now pay this portion.
A 2% administrative fee: This covers the administrative costs your employer incurs to manage the COBRA coverage.
In some rare cases, an administrator may charge up to 150% of the total premium cost (for disability or extended coverage), but the standard rate is 102%.
Understanding Your COBRA Costs
This calculator helps you estimate your potential monthly COBRA premium. By entering your current monthly health insurance premium, the percentage your employer used to contribute, and the standard 2% administrative fee, you can get a clear picture of your out-of-pocket costs.
function calculateCobraRate() {
var monthlyPremium = parseFloat(document.getElementById("monthlyPremium").value);
var employerContribution = parseFloat(document.getElementById("employerContribution").value);
var adminFee = parseFloat(document.getElementById("adminFee").value);
var cobraResultElement = document.getElementById("cobraResult");
// Clear previous results
cobraResultElement.innerHTML = "";
// Validate inputs
if (isNaN(monthlyPremium) || isNaN(employerContribution) || isNaN(adminFee)) {
cobraResultElement.innerHTML = "Please enter valid numbers for all fields.";
return;
}
if (monthlyPremium < 0 || employerContribution 100 || adminFee 100) {
cobraResultElement.innerHTML = "Please enter positive values for premiums and percentages between 0 and 100.";
return;
}
// Calculate the employer's portion of the premium
var employerPortion = monthlyPremium * (employerContribution / 100);
// Calculate the total premium you'll pay (your portion + employer's portion)
var totalPremiumPaidByYou = monthlyPremium + employerPortion;
// Calculate the administrative fee based on the TOTAL premium (100% of premium + employer's portion)
// The standard rate is 102% of the GROUP plan cost.
// The group plan cost is YOUR contribution + EMPLOYER's contribution = monthlyPremium
// So, the employer can charge up to 102% of `monthlyPremium`.
// The calculation needs to reflect what YOU will pay.
// You pay: (Your old share) + (Employer's old share) + (Admin Fee on the WHOLE premium)
// Let's re-evaluate based on the 102% rule.
// The law allows the employer to charge UP TO 102% of the GROUP premium.
// The GROUP premium is the sum of what the employee and employer paid.
// Let's assume `monthlyPremium` is the total group premium cost.
// Your portion under COBRA = (100% of group premium) + (Admin Fee %) of (group premium)
// The employer's contribution percentage tells us how much of the group premium was previously subsidized.
// Your old contribution = monthlyPremium * (1 – employerContribution/100)
// Your new COBRA cost = (monthlyPremium) + (monthlyPremium * (adminFee / 100))
var cobraTotalCostRate = 100 + adminFee; // This is the percentage of the *original* monthly premium
var estimatedCobraPremium = monthlyPremium * (cobraTotalCostRate / 100);
// Display the result
cobraResultElement.innerHTML =
"Your estimated monthly COBRA premium is: $" + estimatedCobraPremium.toFixed(2) + "";
