The cost to deliver video is either billed per terabyte (TB) or per gigabyte (GB). To clear up any confusion, some companies charge per TB while others charge per GB. There are 1000 GB in 1 TB. and 1000 TB in a Petabyte.
1000 GB = 1 TB, 1000 TB = 1 PB (petabyte)
So GB charges are quoted at cents/GB:
$0.01/GB which is equivalent to $10/TB. TB charged in dollars per TB.
So, if 1000 viewers watch 2 hours per day on average in a 30 day month at 3 Mbps connection speed the total bandwidth consumed is 77 TB or 77,252 GB.
If you were to stream the same content at 4K, the total TB would be 540 TB or 540,766 GB.
An average starter price for video delivery is $0.02 /GB or $20/TB. So 77 TB would cost $1540. To break it down on a per-subscriber cost basis for the same bandwidth, it costs $0.73 per subscriber.
Understanding CDN costs are key when you price out your subscription fees or calculate the costs for ad-supported (AVOD) content. Beware of OTT platforms bearing gifts with really low costs for middleware and apps, where the cost per GB is $0.06 ($60/TB) or higher.
So as you become more successful, your CDN fees will eat up all of your profits. Not good.
As mentioned, CDN fees are going to be a big line item and your profitability can depend on what you pay at the pump.
In order to manage expenses and your revenue, it is important to contract with an OTT provider or directly with a CDN provider who can deliver your content to your audience’s geographic region and a committed rate card that will allow you to minimize costs and scale. In general, the more you commit to in terms of TB per month, the lower the cost per TB.
