U2‘s world tour costs $750,000 a day to stage - even when the band has the day off. Bono, The Edge, Larry Mullen Jr. and Adam Clayton’s current 360 Degree tour - which features a huge stage called “The Claw” - is so expensive to run it is yet to make a profit, even after 33 concerts.

The “Get on Your Boots” rockers have played across Europe and North America since kicking off the run of concerts in Barcelona, Spain, on June 30.

The band’s manager Paul McGuinness estimates the group have spent more than $64 million so far entertaining fans. “The engineering problems are enormous and costly. Whether we’re playing or not, the daily overhead is about £470,000,” he told Britain’s The Sun newspaper. “That’s just to have the crew on the payroll, rent the trucks and everything else. There are about 200 trucks in total, including merchandise and catering.”

But with the group touring until late next year, they are still expected to make a substantial profit by the time the shows come to an end.
