When pacman shows the total package size and then the total installed size would it also be possible to show how much extra space is used over the amount of space that those packages already use in my system?

Example:
Package 1 = 6mb and package 2 = 4mb so total installed size is 10mb.
I upgrade those packages. Package 1 is now 7mb and package 2 is 5mb. Total installed size is 12mb but it's only using 2mb extra space on my drive.

So, for example, pacman could output: Actual extra space used: 2MB

Or would this be impossible to determine?

Thanks.
This task depends upon

Reason for closing:  Won't fix
Additional comments about closing:  Partition size and layout is different on every system and we already removed the "free disk space" check becuase it was problematic, not to mention very platform-specific. This is not really the job of the package manager.

Good luck with this one...we have multiple levels of complexity here. Not every package/repo currently ships with a total installed size number. What do we do in this case? We already fudge a bit and don't print installed size unless it exceeds compressed package size, which is still a bit of a hack. We'd possibly double our error in this case if we want to do differences between numbers we may or may not have.

Short answer- this would be very difficult to determine, and I'm not completely sure on the purpose.

The purpose is mainly when you are short on space I suppose.
