The activities of Rotaract clubs are meant for young adults, ages 18-30. The purpose of these activities is personal development into responsible adults and leaders. The members of Rotaract clubs decide themselves about their projects and activities. A Rotary club always sponsors and supports their activities.

The activities of Interact clubs are meant for youth, ages 12-18. Also Interact clubs have Rotary clubs as sponsors. In Interact activities the youth get to influence things that are important to them. This happens via annually planned and realised projects. A Rotary club supports the youth in these projects.

Being a member of both Interact and Rotaract, the youth are able to network locally, nationally and internationally. In Finland, there are Rotaract clubs especially in big localities, but not many Interact clubs.
