Interested in comparing the cost of your different health care options?

You can access the Aon Cost Modeler at the bottom of this page. In order to use the modeler, you will need to enable macros and enter the password. The password can be found on our Documents, Notices, and Forms Insider Page.

Please note that accessing this tool can get tricky. If you are experiencing difficulties, PDF versions of the cost modeler can be found by geographic location on the Documents, Notices, and Forms Insider Page.

When Open Enrollment officially begins on November 5, you will see pricing on the RTI Benefits Portal as part of your enrollment opportunity.

Important: If you are living abroad or in Puerto Rico, you will not be able to use the Aon Cost Modeler.
