Streaming Netflix alone can cap your bandwidth quickly given the statistics from the Netflix page [1]. I have recently experienced this actually (I do not run torrents from home and during the month of December I did not transfer anything from the remote box). Month of December I used 1022 GB out of 1024 GB over 900 GB was from NetFlix.
Using: 1 terabyte = 8,388,608 megabits
Ultra HD: 25 mbps ~= 93.2 hours
HD: 5 mbps ~= 19.5 days
SD: Would be good but hey I bought an HD TV for a reason so that would not be fair to skimp out on quality just because they don't want to introduce cheaper bandwidth caps.
side note It is $10 per 50 GB once you go over the cap with Comcast which is pretty huge for overhead if a user wasn't even aware of the cap. Thankfully they cap it at $200 over your bill.
side note2 this number will only increase - so really that 1 TB cap already needs to see a lift to 2 TB just to start to fulfill the requirements of the newer age web.
Back when I was on cheap and cheerful, capped internet - if you went over the (paltry 100GB, although this was the best part of a decade ago now...) cap, I'd pay an extra £6 on my bill and that was it, regardless of how much I went over by.
Ironically, the price to remove the data cap as part of your package was more expensive than the over-cap charge.
