Gianni Infantino believes he has majority backing for his biennial World Cup plan.
The financial data forms part of an overall feasibility study, of which FIFA presented a summary on Monday with a full 700-page report set to be published.
There has been opposition from European clubs, the top leagues and European governing body UEFA, whose president Aleksander Ceferin has threatened to boycott any additional tournament.
"If I was going to a vote tomorrow, probably the majority would vote in favor of a World Cup every two years," Infantino told a news conference after the summit.
"But it is not the topic, we are looking at the entire calendar and how we can make football better and how many we can bring on board with a new way of organizing the future in football," he added.
