VIDEO: Manny Pacquiao sings!
Ryan Chang of Island Fire Productions said he stood to lose about $50 000 on the concert, even with late sales and walk-ups.
Only 603 tickets had been sold for the show at the Waikiki Shell just days after more than 45 000 people watched Pacquiao retain his WBO welterweight title against Joshua Clottey in Texas.
It was the largest crowd to see a fight in the United States in 17 years.
Pacquiao was going to earn $100 000 at the "Manny Pacquiao Live In Hawaii Concert Celebration."
He made at least $12 million for last Saturday's fight.
Pacquiao, who intends to run for congress in the Philippines later this year, is also an enthusiastic performer at music concerts.
