COBRA health insurance costs the same as the insurance holder's previous health coverage, plus a two percent service charge leveraged by COBRA. The price range of COBRA health insurance is determined by the insurance plan an individual carried prior to switching to COBRA.
COBRA is a health insurance extension plan. Individuals can apply for COBRA coverage after losing their previous coverage due to losing a job, aging out of their parent's coverage or other circumstances. COBRA allows them to keep the same coverage, but they must pay the total cost of the health insurance premium, including any amount a previous employer contributed.
