The world's richest Twenty20 league was approaching its halfway stage before it was suspended indefinitely on Tuesday following bubble breaches in two venues.
"The ballpark figure for revenue loss would be to the tune of 2000 crore rupees (20 billion)," Arun Singh Dhumal, treasurer of the Board of Control for Cricket in India (BCCI), said.
"Given all our contractual obligations, we are yet to find out what would be the actual figure," he said, adding that the governing body's immediate priority was to ensure the league's foreign players returned home safely.
STAR Sports bagged the IPL's television and digital rights for 2018-2022 for 163.48 billion rupees, agreeing to pay about 545 million rupees per game in a 60-match season.
With only 29 games of 60 completed before the pandemic halted this year's IPL, the BCCI could lose a chunk of that pot.
