It varies:
- Airfare depends on country (and is higher than you might expect because of specific ticket requirements)
- Insurance / orientation / blazer
- possibly language school/extra insurance in your host country
- passport and visa
- pins, presents, photos
- spending money / extra trips in your host country/ souvenirs

For most students the cost of the year is between$4,000 - $6,000 ($5,000 - $7,000 $CAD) although this is very much dependent on your spending habits while on exchange.

This does not include what your parents save while you are gone (food, car insurance, etc.)

Rotary provides:
- host families and school
- monthly allowance
- and often lots of extras...
