The most important thing is to understand what Internet Plan you are on.
ie are you on unlimited data, or say 5GB, 10GB, 20GB etc? Check your bill or call your ISP.

Then determine if your ISP also charges for uploads.

My ISP Telstra charge for downloads and uploads. I receive 25GB of data per month, both Up and Down. Also, when I go over my 25GB, I simply get slowed to dial up speeds, however, some ISP charge you a rate ie say 15c per Megabyte. SO it really pays to check your ISP.

Being on XBL doesn't use much bandwith, until you do something, like play mulitplayer games, or say download data off XBL. Also, hosting matches uses allot of data as well. Typically on most nights of say 3 or so hours of Gears of War, I'd download about 300MB and upload about 400 MB. My total usage that day would be 700MB. But if your ISP doesn't count uploads, then your usage would only be 300MB.

Get what I am saying.

There are infinite answers, you must check your ISP.
