Not much information on that yet.
There was a special around christmas for German fans who could purchase a team package for all 7 group games of Team Germany in Cologne (only 500 such packages were available). Those cost 133 € (roughly $150 (US) or $200 (CAN)).
The final schedule for the tournament is supposed to come out on August 1st 2016. Some time after that there should be more information available regarding packages, and pricing of tickets.
At least that would be my guess.
EDIT:
Right now team tickets for the games of Germany and France are available. Tickets for single games of the two host nations will become available after the schedule has been announced.
Team packages for the other 14 nations will become available in October 2016. Single game tickets for games not involving Germany and France will be available in spring of 2017.
There are also the following packages available:
Venue package (includes all 34 games in Cologne): Starting at 729 €
Venue package (includes all 30 games in Paris): Starting at 469 €
Group package (includes all 28 group stage games in Cologne): Starting at 426 €
Group package (includes all 28 group stage games in Paris): Starting at 406 €
Finals package (includes 2 QF, 2 SF, Bronze Medal Game and Final in Cologne): Starting at 351 €
Finals weekend package (includes 2 SF, Bronze Medal Game and Final in Cologne): Starting at 267 €
On average the cheapest single tickets for the games are supposesd to cost about 15 €.
