From where? Google? I just paid $12/yr for a .dev domain on Google Domains.
Here's an unregistered one. "red.dev" is $720/yr from Google:

"god.dev" is cheaper at $180/yr:
https://domains.google.com/m/registrar/search?searchTerm=god...
And, of course asdfasdf.dev is only $12/yr:
https://domains.google.com/m/registrar/search?searchTerm=asd...
Most of the {firstname}.dev domains are in the $300/yr range, but it's uneven. Some names cost more or less than others. I remember seeing one as $1000/yr, but I can't remember what it was.
I double checked my cost. "$180 plus tax"/yr. From Google.
