Paying more for Internet usage over a certain amount — having a “data cap,” in common parlance — will soon be universal for Comcast users, company executives predict.

Speaking on a call with investors Wednesday, Comcast Executive Vice President David Cohen said, “I would predict that in five years Comcast at least would have a usage-based billing model rolled out across its footprint.”

Data caps are already the norm for Comcast users in Huntsville and Mobile, Alabama; Atlanta, Augusta and Savannah, Georgia; central Kentucky; Maine; Jackson, Mississippi; Knoxville and Memphis, Tennesse; and Charleston, South Carolina.

In those locations, the typical user gets 300 gigabytes per month of data, after which they’re billed an additional $10 for every additional 50 gigabytes of data they use.

Comcast said relatively few customers would actually be affected, because 98 percent of national users never exceed the 300 gigabytes per month, the company told Ars Technica.

The caps probably wouldn’t bite into most people’s wallets, but heavy Internet users should get ready for a sting.
