Health insurance premiums in San Diego depend on your age, plan type, and whether you qualify for ACA subsidies. Many San Diego residents who qualify for premium tax credits pay $0–$100/month for a Silver plan. Without subsidies, individual premiums typically range from $300–$700/month depending on age and plan tier. A licensed CA agent will calculate your exact subsidy amount for free.
Outside of the ACA Open Enrollment Period (November 1–January 15), you can still get coverage if you have a qualifying life event — such as losing a job, getting married, having a baby, or losing other coverage. This triggers a 60-day Special Enrollment Period. A licensed CA agent can confirm whether you qualify and help you enroll quickly.
