USAA, American General and Kaiser Permanente earned the highest scores from customers in their respective categories in Insure.com's annual customer satisfaction study.

Overall satisfaction with insurers' customer service went up for everyone except auto insurers, where satisfaction levels held steady. And while satisfaction with life insurers went up, they still dropped below health insurers this year for customer service satisfaction.

We asked more than 5,600 insurance customers nationwide to rate their satisfaction with their auto, home, health and life insurance companies. We collected ratings for 20 large companies for four types of insurance. Click on our insurance tool to get detailed customer satisfaction scores.

Here are percentages of customers saying they are "completely" or "somewhat" satisfied with their insurers' customer service:

  • Auto insurance customers: 80% (2012 results: 80%).
  • Home insurance customers: 76% (2012 results: 73%).
  • Life insurance customers: 67% (2012 results: 63%).
  • Health insurance customers: 71% (2012 results: 61%).

For overall scores, companies were judged on five measurements:

  • Customer service.
  • Claims satisfaction.
  • Value for price paid.
  • Percent who plan to renew.
  • Percent who would recommend the company.

(Life insurance scores did not include claims or renewal questions.)
