Producers announced on Monday that the show has turned profitable after just 21 weeks, or "faster than any Tony Award-winning best musical in more than a decade."
The musical starring Steve Kazee and Cristin Milioti is based on the 2006 film about an unlikely romance between a Czech flower seller and an Irish street musician in Dublin.
Like the film, the musical features songs by Marketa Irglova and Glen Hansard, including "Falling Slowly." It won eight Tonys and last week earned an average ticket price of $124.27.
Made for about $150,000, the original film earned $20 million. A national tour of the musical will launch in the summer of 2013.
The musical was an off-Broadway hit and doesn't suffer a bit from moving to a 1,000-seat Broadway theater.
Traditionally, only about 3 in 10 Broadway shows recoup.
