You really have to appreciate how Comcast really tries to sound advanced with &quot;World&#x27;s First&quot; in the headline.<p>Assuming the upload will again be 1&#x2F;5th the download speeds, you&#x27;re looking at 1Gbps down &#x2F; 200 Mbps up for a total bandwidth of 1.2 Gbps. That means in a 30 day month you can use up to 388,800 GB of bandwidth. Subtract your 300 GB &quot;courtesy bandwidth&quot; and you&#x27;re at 388,500 GB over your courtesy limit. At $10 per 50GB you&#x27;ll need 7,770 separate 50GB &quot;packages&quot; at $10 each totaling $77,700 per month in overages.
