I think your answer was correct, I was just expanding a little. It's difficult to put an accurate number on the issue.
Salt acts as a preservative, that's its main purpose (taste augmentation is secondary).
Foil wrappers prevent oxygen from reaching butter better than paper thus extending its useful life. They also help it from picking up odd flavors which it may otherwise do.
Good answer ChefOno! I freeze all my butter except for a .lb, but what does it matter if it's wrapped in paper or foil, or is salted or unsalted? Just curious.

Depends. Salted or unsalted? Wrapped or unwrapped? Wrapped in paper or wrapped in foil?
Best to freeze what you're not going to need for a while.
