ANSWERED: Comcast's Terabyte Internet Data Usage Plan

The Terabyte Internet Data Usage Plan provides you with 1 TB (1024 GB ) of Internet data usage each month as part of your monthly Xfinity Internet service. If you choose to use more than 1 TB in a month, we will automatically add blocks of 50 GB to your account for an additional fee of $10 each. Your charges, however, will not exceed $200 each month, no matter how much you use. And, we're offering you two courtesy months, so you will not be billed the first two times you exceed a terabyte. This data plan is based on a principle of fairness. Those who use more Internet data, pay more. And those who use less Internet data, pay less.

It is important to know that only a very small percentage of our customers use more than 1 terabyte of data and are not likely to be impacted by this plan, so they can continue to stream, surf, and download without worry. To see your actual usage, sign in to My Account.

A terabyte is a massive amount of data. What can you do with a terabyte each month?
  • Stream between 600 and 700 hours of HD video
  • Play online games for more than 12,000 hours
  • Stream more than 15,000 hours of music
  • Upload or download more than 60,000 hi-res photos



Additional Options

For those who regularly use more than a terabyte in a month, we also offer an Unlimited Data Option.

The Unlimited Data Option costs an additional fee of $50 per calendar month. The fee is independent of actual data usage. The 1 Terabyte Data Usage Plan will not apply to customers who enroll in the Unlimited Data Option.

A Flexible Data Option is also available to our Economy Plus and Performance Starter customers and is specifically designed for casual or light Internet users who typically use 5 GB of data or less each month. Enrollment is optional and provides an automatic $5 credit if your total monthly data usage is less than or equal to 5 GB per month.

However, if you use 6 GB of data or more in any given month, you will not receive the $5 credit and will be charged $1 for each GB of data used over the 5 GB included in the Flexible Data Option (up to $200 per month). These charges would be in addition to the price of your monthly Xfinity Internet service charge.

Available Tools

We offer tools to help you track and manage your usage so there are never any surprises about how much data you use:
  • Data Usage Meter in My Account - Monitor how much data you have used with our Data Usage Meter.
  • Xfinity My Account App - You can also monitor how much data you have used in our mobile app. (Download the Xfinity My Account app.)
  • Notifications - We will send you an "in-browser" notice and an email letting you know when you approach, reach and exceed a terabyte. You can also elect to receive notifications at additional thresholds as well as set up mobile text notifications. Usage notifications will not be sent to customers who enroll in the Unlimited Data Option.
