Understanding WhatsApp's $16 billion price tag
The $16 billion Facebook is paying for WhatsApp may sound absurdly high, but the deal—and the price tag—can be explained as a key way for the social network to expand its global, mobile reach. It's WhatsApp's scale that CEO Mark Zuckerberg is focused on – he predicts it'll hit 1 billion users in just a few years—and he says it'll be key to his vision for "connecting the world"
With WhatsApp, Facebook will become the biggest mobile messaging company in the world—it handles nearly as many text messages as the Telecom industry's entire $100 Billion text messaging business. WhatsApp is quickly expected to surpass the telcos texting volume. And as CFO David Ebersman pointed out on a conference call yesterday, "That's a $100 Billion business for carriers in terms of direct messaging fees. So this is a really valuable service that people are willing to pay for."
And unlike many other high-priced acquisitions—like Instagram, which wasn't making a dime when Facebook bought it—WhatsApp already has a business model and is generating revenue. It's free for the first year, then charges 99 cents annually. There's no word on how many users pay. But Zuckerberg predicts WhatsApp could draw as many as 3 billion people a day, and says he's confident people will be willing to pay for the service.
WhatsApps value for Facebook isn't just its scale—it currently has 450 million monthly active users—but the fact that their engagement is usually high—70 percent use the service every single day. And its growth rate is breaking records: it doubled its user base in the past year and is adding a million new users every day.

Zuckerberg said "services in the world that have 1 billion people using them are all incredible valuable, and from that perspective, we just think that the growth rate that they have today and the monetization model that's early but promising, and in place… We see a pretty clear trajectory ahead."
So how does WhatsApps valuation compare? WhatsApp has nearly twice Twitter's monthly active users, and about THREE times its daily active users; Facebook is paying just about half of Twitter's market cap. And while Facebook is paying 16 times what it paid to buy Instagram, WhatsApp has 15 times Instagram's users at the time Facebook bought it. And unlike Instagram, which is slowly and tenuously rolling out a business model, WhatsApp has already proven how it can make money.
