One Direction may want to consider changing its name to One Billion.

Because that's apparently how much the boy band will have taken in by the time the end of 2013 rolls around.

Go ahead. We'll give you a second to digest that tidbit of info.

According to Business Insider, more than half of that astronomical number stems from concert ticket sales alone.

Then, of course, there's the 30 million records sold, which have generated $300 million.

Meanwhile, the upcoming release of the group's 3-D movie, This Is Us, is expected to earn approximately $150 million on top of the $15 million that 1D's Up All Night: The Live Tour DVD pulled in.

As for the never-ending merchandise that often features the faces of Harry Styles, Zayn Malik, Louis Tomlinson, Liam Payne and Niall Horan? A cool $67.5 million.

Yeah. You do the math.
