You're only worth $1.21 to Facebook

How much does Facebook value its users? In strictly monetary terms, about as much as a bag of chips.

Facebook is raking in a little over $1 billion in sales every three months. That sounds like a big number, but with more than 900 million active users, it means each Facebook user is bringing in just $1.21 a quarter. Facebook's ARPU in the United States and Canada is almost twice its global average, coming in at $2.23 per quarter. Facebook's fastest user growth is coming from developing countries, where the company says the ad market brings in significantly lower sales. Its quarterly ARPU is just 61 cents in those regions.
