Comcast has expanded its data cap to all 39 territories in which it currently offers services.  Comcast Customers now have a 1.2TB data cap on their internet services.  This means that for those that either stream entertainment or upload and download large files via the internet may be hit with additional monthly charges.  Territories that were added in January, 2021 include Connecticut, Delaware, Massachusetts, Maryland, Maine, New Hampshire, New Jersey, North Carolina, New York, Pennsylvania, Vermont, West Virginia and Washington D.C.

Basically, Comcast customers are allowed 1.2TB of data per payment cycle.  If a customer goes over the 1.2TB of data, they will be charged for data at $10 per 50GB of data with a maximum charge of $100 above the customer’s normal monthly bill.  Customers will be given to option to purchase unlimited data for an additional $25/mo.

Comcast claims that this data cap will only effect about 5% of their customers.  They claim that the median amount of data used is around 300GB per month.


Just an example of what would place a customer over this data cap.

If you streamed NetFlix for 4 hours a day at HD you would use roughly 31% of your monthly data allotted at 3GB/hr.  4K Streamed video is 7GB/hr, so that would be roughly 72-73% of your data usage.

If there are more than one person and multiple devices using the data, you can see how easily you would be able to have overages each month.  This estimate does not also include streaming video from other sources such as YouTube, Facebook, Twitter, Snapchat and so on.
