These 4 charts show why ridesharing startup BlaBlacar could be worth $1.6 billion

French ridesharing company BlaBlaCar, which lets people book trips between cities and destinations in advance with drivers who already traveling the route, has just raised another $200 million (£127 million) in funding.

That brings its valuation to $1.6 billion (£780 million), which is quite a lot for a company that has just 2 million monthly active users.

But when we did the math with what we considered to be some conservative estimates, we found that the company could already be seeing some solid revenues. BlaBlaCar takes a 12% cut from the fee drivers charge their passengers. Last year the company said that fee averaged out at around $25 (£16) per ride. Assuming each of its 2 million monthly users take one trip a month, the company could already be generating $72 million (£46.8 million) every year.

These four charts from digital analytics firm SimilarWeb - which doesn't have BlaBlaCar as a client - show that the app is seeing steady growth in downloads and active users in its native France, as well as Russia, Poland, Germany and Spain.
