Why 18 is the Best Age to Lock In Low Health Insurance Premiums
At 18, health insurance premiums are at their lowest point in an adult’s life. A healthy 18-year-old buying their own U65 private plan pays $155 to $185 per month. That same person at 45 pays $265 to $380 per month, and at 60 pays $440 to $620 per month. If you need your own coverage at 18, you are starting from the most favorable premium position available.
📊 According to KFF Health Policy, young adults aged 18 to 25 have the lowest uncompensated care costs and the lowest average healthcare utilization of any adult age group, making them the lowest-risk segment of the individual health insurance market. This is directly reflected in their substantially lower premiums compared to older adults.
Do You Need Your Own Health Insurance at 18?
- You are on a parent’s plan: No action needed. Stay on the plan until you turn 26.
- Parents have no health insurance: You need your own coverage. U65 private plans start at $155/month for healthy 18-year-olds.
- You are starting a job with employer coverage: Enroll in the employer plan at your new hire enrollment period.
- You are starting college: Review the school student health plan vs. a private or marketplace plan. School plans often cost more for less coverage.
- Income is very low: Apply for Medicaid through your state. 18-year-olds in expansion states with income below $20,782 typically qualify for free coverage.
The number one piece of advice for 18-year-olds on health insurance is simple: if you have access to a parent’s plan, stay on it. It is free to you, comprehensive, and available until you are 26. The second piece of advice: if you need your own coverage, call us. At 18, premiums are lower than they will ever be again.
